Example 1

The utility model provides a heat exchange member for a moisture removing device, as shown in fig. 1 and fig. 2, comprising a heat exchange member body 20 arranged on the moisture removing device body 1, wherein the heat exchange member body 20 is provided with a cooling part 21 for introducing a cooling medium so as to exchange heat with the damp and hot air contacting the cooling part 21; the cooling part 21 includes a cavity, a baffle 211; the baffle 211 is arranged in the cavity to form a cooling channel 212 for a cooling medium to pass through together with the inner contour of the cavity; wherein,

the baffle 211 is a heat-conducting fin and has heat-conducting property; at least one baffle 211 is obliquely connected to the inner wall of one side of the cavity to increase the contact area between the baffle 211 and the cooling medium contained in the cooling channel 212, thereby improving the heat exchange efficiency between the baffle and the cooling medium and accelerating the absorption of the cooling medium to the heat of the damp and hot air. Specifically, the cooling medium is located in the cooling passage 212, when the hot and humid air in the dehumidifying device body 1 contacts the cooling part 21, the heat of the hot and humid air is transferred to the outer wall of the cooling part 21, and the cooling medium in the cooling passage 212 absorbs the heat of the outer wall of the cooling part 21, so that the heat of the hot and humid air is finally transferred to the cooling medium, thereby cooling the hot and humid air in the cavity 11. In addition, the baffle 211 and the inner contour of the cavity form a cooling channel 212 together, so that the space of the cooling channel 212 is increased, the space occupied by the cooling channel 212 is reduced, the retention time of a cooling medium in the cavity is prolonged, and the cooling performance of the cooling medium in the cooling channel 212 is fully utilized; replace traditional adoption curved shape pipeline structure as cooling channel's scheme, reduced the space that traditional pipeline structure is crooked and the interval between two adjacent pipeline sections that cause occupies, improved the space size of the cooling channel 212 that same appearance chamber space corresponds promptly, improve the quantity of the coolant that cooling portion 21 held for the heat transfer. Through the slope setting of baffle 211, accelerate the speed that the heat transfer of the moist hot air that the cooling portion outer wall was absorbed reaches the coolant in the cooling channel 212, on the heat transfer of the moist hot air that the cooling portion outer wall was absorbed reached the cooling portion inner wall promptly, partial heat directly transmitted for coolant to the cooling portion inner wall, another partial heat transmits again for coolant behind baffle 211. Further, the length of the baffle 211 which can be accommodated by the cavity is ensured by limiting the included angle between the baffle 211 and the inner side wall corresponding to the position of the cavity.

In an embodiment, the number of the baffles 211 is at least two to form a plurality of flow guide channels to guide the cooling medium to the cooling medium outlet 213 of the cooling part.

In an embodiment, as shown in fig. 2, two adjacent baffles 211 are arranged in parallel, and the cross section of the channel formed by two adjacent baffles 211 for accommodating the cooling medium has a uniform profile dimension along the direction perpendicular to the baffles 211, so that the cooling medium flows smoothly in the channel formed by two adjacent baffles 211, and is not easy to cause turbulence and noise due to the change of the inner size of the cooling channel. Further, all the baffles 211 in the housing are arranged at equal intervals. That is, the cross-sectional profile of the channel formed between any two adjacent baffles 211 along the direction perpendicular to the baffles 211 is uniform, so that the flow velocity of the cooling medium flowing in the cooling channel 212 is uniform or the difference between the flow velocities of the cooling medium flowing through the curve and the flow velocity of the cooling medium flowing in the channel formed by the next two adjacent baffles 211 is small, and the noise caused by unstable flowing of the cooling medium is reduced.

In yet another embodiment, two adjacent baffles 211 are inclined away from each other to extend the time for the cooling medium to flow out of the channel formed by the two adjacent baffles, thereby making full use of the cooling medium.

In one embodiment, as shown in fig. 2, two adjacent baffles 211 are respectively connected to two inner walls of the chamber at opposite positions in a staggered manner. Further, the cooling medium inlet end (corresponding to the cooling medium inlet 14 of the housing 10) of the cooling channel 212 and the cooling medium outlet 213 are respectively located at the outer sides of the two baffles 211 arranged at the outermost side, so as to fully utilize the space of the cavity, so that the space of the cavity is only used for accommodating the cooling medium and the baffles 211, and the amount of the cooling medium accommodated by the cavity is increased.

In an embodiment, the ends of two adjacent baffles 211 are staggered in a direction perpendicular to the baffles 211 to form a cooling channel 212 with a curved shape, so as to form a flow path with a curved shape, so that the flow of the cooling medium is stable and the residence time of the cooling medium in the cooling channel 212 is ensured. The cooling medium entering the cavity firstly flows into a first channel connected with the cooling medium inlet end of the cooling channel 212, then flows into a second channel adjacent to the first channel, and then flows into a third channel adjacent to the second channel, and so on, and the plurality of baffles 211 are reasonably arranged to ensure that the cooling medium flows stably. The adjacent two channels formed by the baffles 211 are in a U shape, so that the flowing stability of the cooling medium is further improved.

Further, the distance between two adjacent baffles 211 is equal to the distance between the end of the baffle 211 and the inner wall of the cavity, so as to reduce the influence of the cooling medium flowing to the curve in the cooling channel 212 on the velocity of the cooling medium, thereby avoiding turbulence.

In one embodiment, as shown in fig. 1, 2, 3, and 4, the cooling portion 21 is provided with a cooling medium outlet 213; the cooling medium outlet 213 communicates with the cooling passage 212 and the cavity 11 of the dehumidifying apparatus body 1, respectively. The cooling medium introduced into the cooling passage 212 from the cooling medium inlet 14 of the dehumidifying apparatus body 1 exchanges heat with the hot and humid air in the cavity 11 contacting the cooling portion 21, so that the cooling medium in the cooling passage 212 absorbs the heat of the hot and humid air in the cavity 11, is discharged into the cavity 11 from the cooling medium outlet 213, and is discharged from the water discharge port 15 of the dehumidifying apparatus body 1 together with the condensed water generated during the cooling process of the hot and humid air. The cooling medium outlet 213 is provided on the cooling part 21 but not on the casing 10 to reduce the number of pipes connected to the casing 10 and simplify a pipe arrangement structure when the dehumidifying apparatus body 1 is installed in the dryer body.

Specifically, in one embodiment, the outer wall of the cooling channel 212 contacting the hot and humid air is a heat conducting sheet structure to ensure the heat exchange effect between the cooling medium in the cooling channel 212 and the hot and humid air. In another embodiment, the heat exchanger body 20 is a heat conducting structure to improve the heat exchange effect with the hot and humid air in the cavity 11.

In one embodiment, in order to save cost and simplify the layout of the internal structure of the clothes dryer body, the cooling medium is cooling water which is cheap and convenient to take, the cooling water can be timely provided for the dehumidifying device body 1 through a water path in the clothes dryer body, the cooling medium does not need to be replaced, and the operation is convenient.

In one embodiment, as shown in fig. 2 and 3, the cooling medium outlet 213 corresponds to the drain port 15 of the casing 10 of the dehumidifying apparatus body 1. The water outlet 15 is located on the bottom wall of the shell 10, and condensed water formed by the damp and hot air in the cooling process drops to the bottom wall inside the shell 10 and is discharged from the water outlet 15, so that the condensed water is discharged conveniently, the condensed water is prevented from being accumulated too much in the cavity 11, the humidity inside the cavity 11 is influenced, and the cooling effect of the cooling part 21 is further influenced. After the cooling medium absorbing the heat of the hot and humid air is discharged from the cooling medium outlet 213, the cooling medium can reach the water discharge port 15 to be discharged as soon as possible under the self-gravity, so that the cooling medium cannot be discharged in time in the cavity 11 and is accumulated in the cavity 11, the humidity of the cavity 11 is not affected, and the dehumidification of the hot and humid air is not facilitated.

In an embodiment, as shown in fig. 3 and 4, a stopping portion 2131 is disposed on a back surface of the cooling medium outlet 213 for stopping the cooling medium in the cooling channel 212 from contacting the hot and humid air during flowing out of the cooling medium outlet 213. Since the temperature of the cooling medium after absorbing the heat of the hot humid air is increased, the stopper 2131 is provided to block the contact area between the cooling medium discharged from the cooling medium outlet 213 into the cavity 11 and the hot humid air, so as to prevent the cooling medium after absorbing the heat from being detrimental to the cooling of the hot humid air. In one embodiment, the heat exchanger body 20 includes a plurality of air passages 22 for receiving hot and humid air, and the hot and humid air generated from the drying drum enters the air passages 22 after entering the cavity 11 from the air inlet 12, so as to prolong the time for the hot and humid air to pass through the cavity 11. The stopper 2131 is arranged to block the cooling medium flowing out from the cooling medium outlet 213 from entering the air passage 22, that is, to prevent the cooling medium absorbing heat of the hot and humid air from flowing into the air passage 22 when the cooling medium is discharged from the cooling passage 212, so as to reduce a contact area between the cooling medium and the hot and humid air, which is increased in temperature due to the absorption of the heat of the hot and humid air, and to prevent the cooling medium absorbing heat from being detrimental to the cooling of the hot and humid air. Further, the stopping portion 2131 is bent to form a surrounding wall structure surrounding the cooling medium flowing out from the cooling medium outlet 213 together with the inner walls of the two sides of the cavity 11, and the surrounding wall structure can be completely or partially closed at the surrounding side to guide the cooling medium to flow to the water outlet 15 and simultaneously separate the air passage 22 from the cooling medium flowing out from the cooling medium outlet 213.

Further, the height of the stopper 2131 is greater than the height of the side wall of the air passage 22 to further ensure that the cooling medium flowing out of the cooling medium outlet 213 does not enter the air passage 22.

Furthermore, the stopping portion 2131 is a heat conducting sheet, the cooling medium discharged from the cooling medium outlet 213 is left along the inner wall of the stopping portion 2131, the hot and humid air in the cavity 11 contacts the outer wall of the stopping portion 2131, and the cooling medium discharged from the cooling medium inlet 14 absorbs part of the heat of the hot and humid air contacting the outer wall of the stopping portion 2131 through the heat transfer function of the stopping portion 2131 which is a heat conducting sheet structure, so that the cooling medium is fully utilized, and the cooling speed of the hot and humid air in the cavity 11 is increased.

In one embodiment, as shown in fig. 2 and 3, the cooling medium outlet 213 is disposed near the air inlet 12 of the housing 10. The damp and hot air generated by the clothes drying cylinder enters the cavity 11 from the air inlet 12, at this time, the humidity of the damp and hot air is high, that is, the humidity and the temperature of the air in the cavity 11 near the air inlet 12 are the highest, and the cooling medium outlet 213 is arranged near the air inlet 12, so that the temperature and the humidity of the damp and hot air at the air inlet 12 are not greatly influenced by the cooling medium discharged from the cooling medium outlet 213. Furthermore, the cooling medium outlet 213 corresponds to the position of the water outlet 15, when the cooling medium and the condensed water formed in the cooling process of the hot and humid air flow toward the water outlet 15, the humidity in a certain space around the water outlet 15 is affected to a certain extent, the temperature and humidity of the hot and humid air at the air inlet 12 are not greatly affected by the temperature and humidity in a certain space around the water outlet 15, and even if the temperature and humidity of the hot and humid air at the air inlet 12 are affected to increase, the hot and humid air at the air inlet 12 exchanges heat with the cooling medium to reduce the temperature and dehumidify in the process of flowing toward the air outlet 13 of the housing 10, so as to ensure that the temperature and humidity of the air discharged from the air outlet 13 meet the limited requirement.

As shown in fig. 2, the stopper 2131 provided on the back surface of the cooling medium outlet 213 is shifted from the air inlet 12 to prevent the hot and humid air introduced from the air inlet 12 from contacting the cooling medium flowing out of the cooling medium outlet 213. Specifically, the air inlet 12 is disposed on one side of the housing 10 close to the water outlet 15, the cooling medium outlet 213 corresponds to the water outlet 15, and when the hot and humid air introduced into the air inlet 12 flows into the air passage 22 of the heat exchange member body 20, the stop portion 2131 is shifted from the air inlet 12, so that a contact area between the hot and humid air introduced into the air inlet 12 and the cooling medium discharged from the cooling medium outlet 213 is reduced, and an influence of the cooling medium discharged from the cooling medium outlet 213 on humidity of the hot and humid air introduced into the air inlet 12 is reduced. If a small part of the hot and humid air contacts the cooling medium, the part of the hot and humid air has a small amount of air, and thus can exchange heat with the cooling medium in the cooling part 21 to remove moisture when passing through the air passage 22.

In an embodiment, as shown in fig. 2, 3 and 4, the cooling medium outlet 213 provided in the cooling portion 21 is disposed on the bottom wall of the cavity. The cooling medium can directly fall to the inner bottom wall of the cavity 11 after flowing out from the cooling medium outlet 213 under the self gravity, so as to reduce the probability of the contact between the cooling medium and the peripheral side contour of the cavity 11, and avoid the increase of the humidity in the cavity 11 caused by the accumulation of the cooling medium on the peripheral side contour surface of the cavity 11, which is not beneficial to the dehumidification of the damp and hot air.

the damp and hot air generated by the drying drum of the clothes dryer body enters the cavity 11, the cooling medium in the cooling channel 212 absorbs the heat of the damp and hot air, the damp and hot air is cooled and condensed to be dehumidified, and the dehumidified air is discharged out of the clothes dryer body from the air outlet of the dehumidifying device body 1. Specifically, as shown in fig. 2, 3 and 5, the casing 10 is provided with an air inlet 12 and an air outlet 13, the air inlet 12 is communicated with the drying cylinder, and the air outlet 13 is communicated with the external environment of the drying machine body. After a drying program of the clothes dryer body is started, the heater of the clothes dryer body heats air entering the clothes drying cylinder, the heated air enables moisture contained in clothes contained in the clothes drying cylinder to be heated and evaporated to form air flow containing water molecules, the air flow containing the water molecules is mixed into hot air in the clothes drying cylinder under the guidance of a fan of the clothes dryer body to form damp and hot air with higher temperature and humidity, the damp and hot air generated by the clothes drying cylinder enters the cavity 11 through the air inlet 12 and contacts the cooling part 21 of the heat exchange part body 20 positioned in the cavity 11 to be cooled, the damp and hot air forms condensed water in the cooling process to be dehumidified, the air after being cooled and dehumidified is discharged into the external environment of the clothes dryer body, the influence on the temperature and the humidity of the environment where the clothes dryer body is positioned is reduced, and environmental pollution is avoided; and the damp and hot air in the clothes drying cylinder is discharged in time, so that the drying procedure of the clothes dryer body is accelerated. Further, the temperature and humidity of the air exhausted into the external environment of the dryer body after being processed by the dehumidifying device body 1 can be controlled by limiting the heat absorption performance of the cooling portion 21, for example, the temperature of the air exhausted by the dryer body can be controlled to be slightly lower than the room temperature, the humidity is a humidity standard comfortable for life, and when the temperature is in a hot season, the temperature of the environment around the dryer body can be properly adjusted, so as to improve the user experience. The cooling medium inlet 14 of the casing 10 communicates with the cooling passage 212 to introduce the cooling medium.

In one embodiment, the dehumidifying apparatus body 1 is provided with a partition for dividing the cavity 11 into two regions; the cooling portion 21 and the hot and humid air are respectively located in the two separating members, so that the cooling portion 21 and the hot and humid air entering the cavity 11 are respectively located in two relatively independent spaces, and the hot and humid air is prevented from forming condensed water in the cooling process to cause the outer wall of the cooling portion 21 to contact with more moisture, which is not beneficial for the cooling portion 21 to absorb heat of the hot and humid air. Further, in an embodiment, the heat exchanger body 20 includes a plurality of air channels 22 for receiving hot and humid air, and the cooling portion 21 and the air channels 22 are respectively located at two sides of the partition, so that the cooling portion 21 and the air channels 22 are respectively located in two relatively independent spaces.

Further, the heat exchange member body 20 includes an air passage 22 for receiving hot and humid air, and the cooling part 21 is located above the air passage 22.

In one embodiment, as shown in fig. 2 and 3, the cooling portion 21 is provided with an opening; opening into the curved cooling channel 212. Because of the moisture removal device body 1 is used for the dryer body, in order to practice thrift the cost and simplify the layout of dryer body inner structure, coolant is the cooling water, and the cooling water is cheap and take the convenience, can in time provide the cooling water to moisture removal device body 1 through this internal water route of dryer, need not to change coolant, simple operation. The cooling water absorbs heat and the temperature rises, because clothes dryer body water usually contains easy scale deposit ions such as calcium ion, magnesium ion, and the scale deposit can be produced to the in-process that the cooling water temperature rises, and the open-ended setting of cooling portion can be used to look over the condition that the scale deposit formed and in time clear up the scale deposit.

Further, the outer contour of the opening of the cooling portion 21 abuts against the inner wall of the housing 10 to form a closed cooling channel 212, so as to prevent the cooling medium inside the cooling channel 212 from leaking. Furthermore, the cooling part 21 is open to form the opening, and the opening has a large outline, so that scale in the cooling channel can be observed and cleaned conveniently; when the heat exchange element body 20 is installed, the open end of the cooling portion 21 abuts against the inner wall of the casing 10, and the cooling medium in the cooling channel 212 does not overflow the cooling channel 212. It should be understood that when a gap is left between the outer contour of the opening of the cooling portion 21 and the inside of the housing 10, the cooling portion 21 is placed in an opening direction in order to prevent the cooling medium in the cooling passage 212 from leaking from the opening thereof.

Further, the height of the baffle 211 is smaller than the height of the contour of the peripheral side of the receiving cavity, so that the processing of the cooling portion 21 is facilitated, the requirement for the processing accuracy of the baffle 211 is reduced, and the requirement that the height of the baffle 211 is higher than the height of the contour of the peripheral side of the receiving cavity when the processing is performed, so that the outer contour of the opening of the cooling portion 21 abuts against the inner wall of the housing 10 is influenced, and the cooling channel 212 cannot be closed, and when the cooling medium in the cooling channel 212 is more or flows more rapidly, the cooling medium in the cooling channel 212 is prone to leaking from a gap between the outer contour of the opening of the cooling portion 21 and the inner wall of the housing 10.

In one embodiment, as shown in fig. 1 and 2, the cooling medium outlet 213 corresponds to the position of the drain 15 of the housing 10.

As shown in fig. 1, the stopper 2131 provided on the back surface of the cooling medium outlet 213 is shifted from the air inlet 12 to prevent the hot and humid air introduced from the air inlet 12 from contacting the cooling medium flowing out of the cooling medium outlet 213. Specifically, the air inlet 12 is disposed on one side of the housing 10 close to the water outlet 15, the cooling medium outlet 213 corresponds to the water outlet 15, and when the hot and humid air introduced into the air inlet 12 flows into the air passage 22 of the heat exchange member body 20, the stop portion 2131 is shifted from the air inlet 12, so that a contact area between the hot and humid air introduced into the air inlet 12 and the cooling medium discharged from the cooling medium outlet 213 is reduced, and an influence of the cooling medium discharged from the cooling medium outlet 213 on humidity of the hot and humid air introduced into the air inlet 12 is reduced. If a small part of the hot and humid air contacts the cooling medium, the part of the hot and humid air has a small amount of air, and thus can exchange heat with the cooling medium in the cooling part 21 to remove moisture when passing through the air passage 22.

In one embodiment, as shown in FIG. 2, a distance is provided between the cooling medium outlet 213 and the end of the cooling channel 212. When the cooling medium flows to the cooling medium outlet 213 in the cooling channel 212, part of the cooling medium flows from the cooling medium outlet 213 to the water outlet 15 after flowing into the cavity 11, and part of the cooling medium continues to flow to the end of the cooling channel 212 in order to achieve a certain flow splitting effect, so as to avoid that the cooling medium flowing to the end of the cooling channel 212 cannot be discharged from the cooling medium outlet 213 in time to form turbulence and cause noise when the cooling medium outlet 213 is arranged at the end of the cooling channel 212.

In one embodiment, as shown in fig. 2, 3 and 4, the heat exchange body 20 includes an air passage 22 for receiving hot and humid air. The air passage 22 is used to guide the flow of hot and humid air, so that the hot and humid air entering the air passage 22 contacts the cooling part 21 for cooling. Further, the air channel 22 is formed by a plurality of fins 23 or a plurality of ejector pins, and the fins 23 have certain thermal conductivity and function to assist heat dissipation of the hot and humid air in the air channel 22. When the cooling portion 21 is located above or beside the air channel 22, the opening below the air channel 22 formed by the fins 23 or the ejector pins is beneficial to removing condensed water formed by condensing the damp-heat air in the air channel 22 in the cooling process, and the condensed water falls onto the inner wall of the casing 10 from the opening below the air channel 22 and is discharged out of the dehumidifying device body 1 from the water outlet 15 on the casing 10 corresponding to the position.

In one embodiment, as shown in fig. 3, the space occupied by the cooling portion 21 in the cavity 11 is one third to one half of the space occupied by the air channel 22 in the cavity 11, so as to increase the height of the air channel 22 and increase the amount of the hot and humid air contained in the air channel 22, and the hot and humid air can be dispersed in the air channel 22, so as to prevent the hot and humid air from being gathered in the air channel 22 due to too small space of the air channel 22, which is not beneficial to the heat transfer of the hot and humid air.

In one embodiment, as shown in fig. 2, 3, 5, the housing 10 includes a first housing 16, a second housing 17; the first housing 16 and the second housing 17 together sandwich the cavity 11. The first housing 16 is detachably connected to the second housing 17 to facilitate attachment and detachment of the heat exchange body 20.
