Description
Technical Field
The present application relates to the field of air conditioning technologies, and for example, to a heat sink and an outdoor unit of an air conditioner.
Background
The frequency conversion power device is an important component in the frequency conversion air conditioner, and the higher the frequency of the compressor is, the more the heat productivity of the frequency conversion power device is. In addition, because the design of the frequency conversion power device is compact, the heat flow and the power density of the frequency conversion power device in the working process are continuously increased. Therefore, the cooling performance and reliability of the air conditioner under high-temperature working conditions are seriously affected by the heat dissipation problem of the variable-frequency power device.
For a multi-split air conditioner, a variable frequency power device is mainly packaged by an Insulated Gate Bipolar Transistor (IGBT) array and a rectifier bridge chip, which is called a variable frequency module for short. The frequency conversion module generally carries out heat dissipation and cooling in an air cooling aluminum fin mode. However, under the working condition of high ambient temperature, the temperature of the frequency conversion module is increased sharply because the high heat flux density and high power of the frequency conversion module cannot be effectively dissipated by using an aluminum fin radiator. In order to ensure the safety of the frequency conversion module and avoid the frequency conversion module from being burnt due to overheating, the frequency conversion module is generally prevented from being overhigh in temperature by adopting a compressor frequency reduction mode, but the refrigeration capacity of the air conditioner is greatly reduced in a high-temperature environment.
In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:
the current radiator has insufficient heat dissipation capacity on the frequency conversion module under the high-temperature refrigeration working condition, so that the air conditioner greatly reduces the frequency, and the environment refrigeration effect in high-temperature days is poor.

By adopting the embodiment, the temperature uniformity of the base is improved through the temperature uniformity element, heat is transferred to the blowing plate fins of the blowing plate fin group through the base, and the heat transfer working medium conducts heat in a phase change manner in the blowing channels of the blowing plate fins, so that the blowing plate fins not only can achieve the purpose of efficient phase change heat transfer, but also improve the temperature uniformity and the heat dissipation efficiency of the whole radiator. The radiator realizes the purpose of efficiently radiating the frequency conversion module under the high-temperature working condition, and ensures the refrigeration effect of the air conditioner under the high-temperature working condition.
In practical application, the temperature equalizing element 20 transfers heat of the frequency conversion module to the base 10, the base 10 transfers the heat to the blowing plate fins 30, and a heat transfer working medium on one side of the blowing plate fins 30, which is in heat conduction contact with the base 10, is heated, rises in temperature and changes phase, flows along the blowing channel 301, is mixed with a heat transfer working medium with lower temperature, transfers the heat, reduces the temperature, and improves the heat dissipation efficiency. The external air flow flows through the surface of the blowing plate fins 30, so that the air circulation on the surface of the blowing plate fins 30 is accelerated, the blowing plate fins 30 are cooled, and the heat dissipation efficiency of the radiator is improved.
The temperature equalization member 20 may be welded to the base 10. Therefore, the temperature equalizing element 20 and the base 10 can be fixedly connected, and the fitting degree of the base 10 and the temperature equalizing element 20 is improved, so that the heat transfer efficiency between the base 10 and the temperature equalizing element 20 is improved. Optionally, the base 10 and the temperature equalizing element 20 are bonded by coating a heat conductive silica gel. Optionally, a heat conducting sheet may be disposed between the base 10 and the temperature equalizing element 20. In this way, the heat conduction efficiency between the base 10 and the temperature equalizing element 20 is improved. Optionally, the material of the base 10 is aluminum. In practical applications, the temperature equalizing element 20 can be embedded in the first surface 101 of the base 10, or can be disposed to be attached to the first surface 101 of the base 10.
Optionally, a plurality of blowing plate fins 30 are evenly spaced on the second surface 102 of the base 10. Wherein the fin face of the blow-up plate fin 30 is perpendicular to the second surface 102 of the base 10. The heat transferred by the base 10 is rapidly dispersed by the blowing plate fins 30, and the airflow flows through the gaps between the adjacent blowing plate fins 30 to dissipate heat and cool the blowing plate fins 30. The blowing expansion plate fins 30 enlarge the heat dissipation area of the radiator, and improve the heat dissipation efficiency of the radiator. Optionally, the blow-up plate fins 30 are attached to the second surface 102 of the base 10 or partially embedded in the second surface 102 of the base 10. In practical applications, where the blow-up plate fins 30 are partially embedded in the second surface 102 of the base 10, the depth of the blow-up plate fins 30 embedded in the base 10 is H, H > 5 mm. Thus, the larger the depth of the blowing plate fins 30 embedded in the base 10 is, the larger the contact area between the blowing plate fins 30 and the base 10 is, the better the heat conduction effect is, and the improvement of the heat conduction efficiency between the blowing plate fins 30 and the base 10 is facilitated.
Optionally, the blow-up plate fins 30 comprise opposing first and second faces, with the blow-up channels 301 disposed on the first and/or second faces. Wherein the surface of the inflation channel 301 is convex. The surface where the inflation channel 301 is not provided is a plane. Under the condition that the surface of the blowing channel 301 is a convex surface, the heat dissipation area of the blowing plate fins 30 can be further enlarged, and the heat dissipation efficiency is further improved. Under the condition that the inflation channel 301 is arranged on both the first face and the second face, the inflation channel 301 arranged on the first face and the inflation channel 301 arranged on the second face are the same inflation channel; or the first face is provided with a first inflation channel, and the second face is provided with a second inflation channel. Wherein, the first inflation channel and the second inflation channel are respectively of a closed structure.
Optionally, the blown sheet fin 30 includes a plurality of discrete nip points. The channels 201 between adjacent nips communicate with each other to form a blow channel 301. Alternatively, the shape of the cross-section of the nip may be circular, elliptical or polygonal. Wherein, under the condition that the cross section of the rolling point is polygonal, the edge of the rolling point is rounded.

In practical application, as shown in fig. 2, the first row of rolling points includes a first rolling point 306 and a second rolling point 307 which are alternately arranged. Wherein the cross-sectional area of the first rolling point 306 is smaller than the cross-sectional area of the second rolling point 307. The second row of nips includes a plurality of third nips 308 arranged in sequence. Wherein the cross-sectional area of the third rolling point 308 is equal to the cross-sectional area of the second rolling point 307. In the embodiment of the present disclosure, the number of the first rolling point 306, the second rolling point 307, and the third rolling point 308 is not limited. In addition, the rows of the rolling points of the blown sheet fins 30 are N rows, and N is more than or equal to 2.
Alternatively, as shown in connection with FIG. 3, the second surface 102 of the base 10 is provided with a mounting plate 40, the mounting plate 40 being provided with a plurality of mounting slots into which the blow-up plate fins 30 are mounted. Wherein the mounting plate 40 is in heat conducting contact with the base 10. Alternatively, the mounting plate 40 may be welded to the base 10. In this way, not only can the connection and fixation between the mounting plate 40 and the base 10 be realized, but also the fit degree between the base 10 and the mounting plate 40 can be improved, so that the heat transfer efficiency between the base 10 and the mounting plate 40 can be improved. Optionally, the base 10 and the mounting plate 40 are bonded by coating a heat conductive silicone. Optionally, a heat conducting sheet may be further disposed between the base 10 and the mounting plate 40. Thus, the efficiency of heat conduction between the base 10 and the mounting plate 40 is advantageously improved. Optionally, the mounting plate 40 is made of aluminum. In practical applications, the mounting plate 40 may be embedded in the second surface 102 of the base 10, or may be disposed to be attached to the second surface 102 of the base 10.
Optionally, the blow-up plate fins 30 are inserted into the mounting slots. The blowing plate fins 30 are removably attached or fixedly attached to the mounting plate 40. Optionally, the depth of the mounting groove is greater than 5 mm. Like this, the larger the depth that the inflation plate fin 30 is embedded in the mounting plate 40, the larger the contact area of the inflation plate fin 30 and the mounting plate 40 is, the better the heat conduction effect is, and the improvement of the heat conduction efficiency of the inflation plate fin 30 and the mounting plate 40 is facilitated. Optionally, the mounting groove is a through groove. The mounting plate 40 constrains and secures the blowing plate fins 30 by the mounting slots. The end faces of the blowing plate fins 30 are in direct heat conducting contact with the base 10. Alternatively, the blow-up plate fins 30 may be welded to the mounting plate 40. Optionally, the blowup plate fins 30 and the mounting plate 40 are bonded by coating a thermally conductive silicone. Optionally, the blow-up plate fins 30 snap into the mounting slots of the mounting plate 40.
