In general, the welding process in a ship is one of the important processes occupying about 60% of the entire shipbuilding process. In shipbuilding, several shapes of hull blocks are manufactured independently, and then these blocks are combined with each other in a dock . In other words, 250 ~ 400 hull blocks are made to dry one medium and large ship, and there are about 200 welded cells inside the hull block (there are two vertical welds per cell), so one ship is dried In order to do so, many vertical intersections must be welded.

In order to solve this problem, a worker wears a cold air vest using compressed air so that the temperature of the worker's body temperature is increased. .

The cold wind vest is usually manufactured in two types. The first type is a compressed air mass consumption type cold wind vest using only compressed air and a cold wind vest (7 bar based consumption flow rate: about 1050 LPM). Especially, in the case of a cold wind vest using only compressed air, There is a problem that it is difficult to maintain a pleasant feeling when worn. The second type is a cold wind vest using compressed air and a vortex tube (7 bar reference consumption flow rate: about 540 LPM), which allows the flow rate to be adjusted, thereby maintaining a pleasant feeling, but the flow rate is relatively large and the unit price is high.

Here, the vortex tube used in the cold wind vest is more specifically described as a cooling device which is inexpensive, reliable, and requires no maintenance, and is used as a solution to the local cooling problem in various places in an industrial field. Generally compressed air (compressor) used in the industrial field is used as the driving energy source. In addition, the vortex tube produces cold air and hot air at the same time with no mechanical drive, temperature control range is from -46 ° C to + 127 ° C, cold air flow adjustment range is 4248 SLPM at 28 SLPM, Is 2571 Kcal / hr.

These vortex tubes are used for cooling of electronic control and communication equipment, local cooling of machining processes (coolant substitution), cooling of CCTV cameras in high temperature environments, coagulation of the melt, cooling of soldering or welding parts, cooling of large- It is used for the cooling of mechanical seal parts and the production of performance test equipment for severe low temperature environment composition.

The body 110 is formed with a swirl chamber 111 and a compressed air inlet 112. The body 110 has a receiving port 113 formed at one side thereof and a hot air outlet 114 formed at the other side thereof.

At this time, the body 110 may be manufactured by applying MC Nylon having a low thermal conductivity to improve weight and efficiency. That is, it is manufactured by applying MC Nylon which is lighter in weight and superior in cooling power than conventional aluminum or stainless steel.

For reference, the MC nylon is a kind of engineering plastics, which is different from the polymerization and molding methods in comparison with the general NYLON-6. However, as a polymer of a crystalline substance produced by using a chemical component as a catalyst, caprolactam has mechanical strength and self- Is superior in heat resistance and is used for metal substitution. It is a material that can be used continuously at high speed and high temperature.

First, as another embodiment of the present invention, a structure for keeping the airtightness and controlling the flow rate introduced through the compressed air inlet 112 will be described.

As shown in FIGS. 6 and 7, the air cooler 100A has a throttle valve and an inlet side sealing member 127 of the vortex generator 120 configured in an annular shape to maintain the internal airtightness of the vortex generator 120. The sealing member 147 is provided.

The inlet side sealing member 127 of the vortex generator 120 is inserted into the first sealing groove 124 (see FIG. 8) formed on the outer surface of the vortex generator 120 inserted into the body 110 and then the vortex. By being in close contact with the outer surface of the generator 120 and the inner surface of the body 110, it is configured to maintain the airtightness between the outer surface of the vortex generator 120 and the inner surface of the body 110.

The throttle valve sealing member 147 is also inserted into the second sealing groove 144 (see FIG. 6) formed on the outer surface of the throttle valve 140 inserted into the body 110 as shown in FIG. 7. By being in close contact with the outer surface of the throttle valve 140 and the inner surface of the body 110, it is configured to maintain the airtight between the outer surface of the throttle valve 140 and the inner surface of the body 110. The throttle valve 140 is fixed to the fixed vortex chamber 111 by a throttle valve fixing hole 141 inserted through the throttle valve fixing hole 115 formed at the end of the vortex chamber 111.

In addition, the air cooler (100A) is coupled to the compressed air inlet 112 of the body 110, to connect the external air hose, the compressed air inlet to adjust the flow rate of cold air according to the physical condition of the operator ( It further comprises a connector 150 having a valve to adjust the flow rate of air flowing into the 112. 6 and 7 illustrate the connector 150 as a valve nipple having a butterfly valve 153, as shown in FIGS. 6 and 7, having a valve manually controlled or through a cold air outlet 121. Sensing the temperature of the discharged cold air to automatically adjust the flow rate flowing into the compressed air inlet 112 may be configured to be connected to the external air supply means.

Next, the configuration of the air cooler 100A that allows the coolant discharge flow rate to be structurally increased or decreased in comparison with the structures of Figs. 3 to 5 will be described.

FIG. 8 is a cross-sectional view of the vortex generator 120 reduced or enlarged according to the flow rate of the cooling air in the configuration of FIG. 6, and FIG. 9 is the orifice sleeve 130 reduced or enlarged according to the flow rate of the cooling air in the configuration of FIG. 6. 10 is a partial cross-sectional view of the vortex chamber 111 showing an internal configuration including a throttle valve 140 and a coupling portion of the vortex chamber 111 that is reduced or enlarged according to the flow rate of cooling air in the configuration of FIG. 6. to be.

6 to 8, the variable structure of the vortex generator 120 in the case where the size of the air cooler 100A is varied for varying the cool air flow rate will be described.

6 to 7, the vortex generator 120 includes a chamber 125 (see FIG. 4) on the side of the vortex generator inlet a (see FIG. 4) to form a swirling vortex of air introduced through the compressed air inlet 112. And the other end is positioned in the interior of the chamber 125 in the form of a turbo-wing having a large interval so as to be located inside the chamber 125. The outer circumferential surface of the chamfer 125, (126) are arranged at predetermined angular intervals.

In this case, the size of the air cooler 100A varies according to the flow rate, and accordingly, the size of the vortex generator 120 also varies. In this case, the nozzle inner diameter 125b (see FIG. 8) connecting the ends of the nozzles 126 located inside the chamber 125 is adjusted to the nozzle inner diameter 125b (see FIG. 8) 125c, see Fig. 8) is formed to have a ratio of 2.5 to 1.8: 1.

8 shows an example of a vortex generator 120 of an air cooler 100A having a maximum flow rate of 600 L (600 L / min), wherein the nozzle inner diameter 125b is 13 mm in diameter and the chamber depth is 7 mm . That is, the ratio between the nozzle inner diameter 125b and the chamber depth 125c is 1.86 to 1, and the nozzle inner diameter 125b, which is variable in size according to the flow rate, is the nozzle inner diameter of the vortex generator 120 125b and the chamber depth 125c and the ratio.

 In addition, the ratio of the nozzle outer diameter 125a to the chamber depth 125c is formed to have a ratio in the range of 6 to 7: 4 to 3. 8, the nozzle outer diameter 125a is 20 mm, the chamber depth 125c is 7 mm, and the ratio of the nozzle outer diameter 125a and the chamber depth 125c is about 600 mm / 2.86: 1, it can be understood that the above condition is satisfied.

The reason why the nozzle outer diameter 125a or the nozzle inner diameter 125b and the chamber depth 125c have a certain ratio is that the air introduced through the compressed air inlet 112 flows into the nozzle 126 according to the flow rate, To establish the volume and cylindrical structure within the chamber 125 to form an optimal condition for stagnation within the chamber 125 so as to form a swirling flow of the maximum velocity as it is being rotated by the chamber 125. [

That is, the chamber depth 125c, the nozzle outer diameter 125a, and the nozzle inner diameter 125b (see FIG. 8) of the vortex generator 120 have a maximum vortex when the size of the vortex generator 120 changes according to the required cold air flow rate. It is enlarged or reduced to have a certain ratio to form.

Next, the variable structure of the orifice sleeve 130 when the size of the air cooler 100A for varying the cold air flow rate is changed will be described.

The orifice sleeve 130 is approximately 1: 1.5 to 1: 3.5 ratio of the inner diameter of the orifice sleeve inlet 130a and the inner diameter of the orifice sleeve outlet 130b for energy separation by optimal separation between the outer vortex and the inner vortex. It is formed to have a ratio between.

And the inner diameter of the orifice sleeve 130b and the length of the orifice sleeve 130 is formed to have a ratio of approximately 1: 2.5 to 1: 3.5.

As described above, the ratio of the inner diameter of the orifice sleeve inlet 130a and the inner diameter of the orifice sleeve outlet 130b is approximately 1: 1.5 for the orifice sleeve 130 to separate energy by the optimal separation between the outer vortex and the inner vortex. And the ratio between 1 to 3.5 and the inner diameter of the orifice sleeve 130b and the length of the orifice sleeve 130 are approximately 1: 2.5 to 1: 3.5. By increasing the diameter of the vortex at a constant rate so that the vortices formed by the nozzle 126 and the chamber 125 of the 120 are maximally transferred from the inner vortex to the outer vortex according to the angular kinematic preservation law. In order to ensure that the cold air discharged through the cold air outlet 121 has the lowest temperature.

FIG. 9 shows an example of an orifice sleeve 130 of an air cooler 100A having a maximum flow rate of 600 L (600 L / min), and the inner diameter of the orifice sleeve inlet 130a is 8 mm and the inner diameter of the orifice sleeve outlet 130b. Silver 10mm, the length of the orifice sleeve 130 was configured to have a 30.8mm.

In this case, the ratio of the inner diameter of the orifice sleeve inlet 130a: the inner diameter of the orifice sleeve 130b is 1: 1.25, and the ratio of the length of the orifice sleeve 130b to the inner diameter of the orifice sleeve 130b is It turns out that it has the said range as an internal diameter 1: 3.08.

Next, the variable structure inside the swirl chamber 111 when the size of the air cooler 100A for varying the cool air flow rate is variable will be described.

As shown in FIG. 10, when the throttle valve 140 is inserted into the vortex chamber 111 and screwed together, an end of the throttle valve 140 is throttled at a coupling position in close contact with the inner surface of the vortex chamber 111. The tab portion 111c is formed to prevent the over-insertion of the valve 140 as well as to convert the outer vortex into the inner vortex while losing energy and discharging the thermal energy of the outer vortex through the throttle valve 140. .

At this time, regardless of the change of the size of the air cooler 100A according to the variation of the cool air flow rate, the tab portion angle 111d between the tab portions 111c forming the truncated conical shape is formed to be in a range between 45 ° and 70 ° .

The inner diameter of the vortex chamber outlet 111a formed by the minimum inner diameter of the tab portion 111c increases with a value within a range of about 0.5 mm to 1.5 mm per 200 L / min cool air flow rate.

FIG. 10 shows the engagement position with the throttle valve 140 inside the vortex chamber 111 mounted on the air cooler 100A having a size configured to discharge the maximum air flow rate of 600 L / min, and the vortex chamber outlet 111a. The inner diameter of) is formed to 5.5mm, and the tab buoyancy angle 111d is configured to have 60 °.

That is, in the case of the swirl chamber 111 mounted on the air cooler 100A of a size configured to discharge a cool air flow rate of up to 400 L / min, the tab angle of incidence 111d forming the vortex chamber outlet 111a of the swirling indoor part is Is formed to have a specific angle among the angles in the range of 45 to 70 degrees, but the inner diameter of the vortex chamber outlet 111a is formed to be approximately 4.5 mm.

As described above, varying the size of the tab buoyancy angle 111d and the vortex chamber outlet 111a according to the size of the air cooler 100A is such that when the outer vortex including heat of the outer vortex is discharged to the throttle valve, This is to discharge the heat so that heat exchange does not occur.

Hereinafter, the operation of the air coolers 100 and 100A using compressed air according to the present invention will be described.

The compressed air supplied through the compressed air inlet 112 of the body 110 is injected into the swirl chamber 111 while rotating at high speed through the vortex generator 120. The compressed air injected here is moved to the end of the vortex chamber 111 while causing a vortex such as whirlwind, and the heated air is discharged to the outside through the hot air outlet 114 and the remaining air is not discharged. It turns back and hits the wall, forming a vortex and flowing back. The cool air generated in the backwashing process is discharged to the outside through the cool air discharge port 121.

The reason why the internal vortex loses heat is that the air that swirls on the inner wall of the swirling chamber 111 flows into one side in a high temperature state and part of the air is discharged and the other swirls in the same direction in the inside of the high temperature vortex, When it is discharged to the opposite side and discharged, the two vortices rotate in the same direction and at the same speed.

However, due to the law of conservation of angular momentum (rotational momentum) in the law of mechanics, the gas which rotates the outer periphery with large turning radius must flow into the narrow radius of rotation and circulate, and the rotation speed must be increased. However, 100, 100A) In (100), the rotation angular velocity of the circulating air is not accelerated, but is the same as when the outer periphery is turned, because the air inside has lost angular momentum.

The internal air that lost the angular momentum soon lost energy, and as a result, the temperature dropped. The energy lost inside the air is transferred to the rotating air and the air that rotates the outside gets hot.

As a result, the compressed air is vortexed so that the inner air is cold and the outer air is separated by hot air.

In addition, when the sizes of the air coolers 100 and 100A are varied to change the flow rate of the cold air, as illustrated in FIGS. 6 to 10, the tab portion 111c and the nozzle outer diameter 125a of the vortex generator 120 and Nozzle inner diameter 125b (see FIG. 8), inner diameter of the orifice sleeve inlet 130a of the orifice sleeve 130, inner diameter of the orifice sleeve outlet 130b, length of the orifice sleeve 130, tab portion inside the vortex chamber 111 By varying the tab side angle 111d of the 111c and the vortex chamber exit 111a so as to satisfy a predetermined condition, an optimum cooling effect can be obtained even when the size of the air cooler is varied.
