Description

Cooling room heat exchange hot water cooler and its manufacturing method {String Heat Exchanger Water Cooler and Its Fabrication Method}

The present invention relates to a manufacturing technology of a cooling system capable of cooling hot water to an indoor temperature using a ventilator and a seal, and more particularly, by using a characteristic in which water flows down a real surface and has a diameter 1. From 5 to 5mm thick thread is 750 to 2000mm in length at intervals of 3 to 40mm vertically adjoining hundreds to the recommended number of threads and hot water is injected into the upper portion to allow the hot water to flow down the thread surface to reach the lower portion. It relates to a cooling chamber heat exchange hot water cooler manufacturing technology for cooling the hot water by passing the indoor air in a direction perpendicular to the hot water flow until a fan.

1 shows the indoor air (4) flowing horizontally by a fan with hot water (3) flowing down the surface of the cooling chamber (2) hundreds (2,113 yarns 1mm thick per 25x25cm2, 365 yarns 2.5mm) The phenomenon in the normal operation of the hot water cooling module 1 to cool is shown. When cooling the hot water with air, effective cooling is possible by maximizing the contact area between the hot water and the air and maximizing the contact time. In order to maximize the contact area, it is possible to use as many cooling chambers as possible in the cross-sectional area of the hot water cooling heat exchange part 5 of the hot water cooling module (1). As a result, since the hot water is not cooled smoothly by blocking the flow of air, an optimal cooling chamber (2) per unit area of the hot water cooling heat exchange area (50) cross-sectional area should be used in consideration of the proper number and spacing of the cooling chamber. In order to maximize the time, the length of the cooling chamber should be increased. However, since the cooling effect does not have a cooling effect from a certain length while the cooling chamber flows down, an appropriate cooling chamber length should be selected to lower the manufacturing cost.

The cooling system using the current fan is a cooling system in which hot water is sprayed from the upper part and the injected hot water is cooled by the air by the fan, so that water droplets are released to the outside of the device during cooling by the strong wind of the fan. It is possible to replenish the cooling water by accelerating the water leakage due to the external leakage of water droplets, and the injected hot water falls at a high speed, so the cooling time of the hot water is short and the cooling efficiency is low. Operation is a disadvantage. In addition, the chiller cooler uses a refrigerant to cool the hot water is excessive power consumption is the biggest disadvantage. The cooling chamber heat exchange hot water cooler provided through the present invention has the advantage of eliminating the above disadvantages of the present cooling device.

An object of the present invention is to manufacture a high-efficiency hot water cooling heat exchanger using a specially manufactured cooling chamber in response to the demands described above, and can be installed indoors developed by using the same, and cooling the heat generating system by circulating a small amount of cooling water. It is to provide a high efficiency cooling chamber heat exchange hot water cooler that can be made and also to provide a method of manufacturing such a hot water cooler.

Cooling room heat exchange Hot water cooler: A device that cools hot water by using a hot water cooling heat exchanger made of a cooling room as the main core device, which can be installed indoors, and cools the heat generating system by circulating 30 ~ 100kg of cooling water.

In order to achieve the object as described above, according to the embodiment of the present invention, the thickness of the cooling chamber 2 is determined between the adjacent adjacent cooling chamber 2 and the cooling chamber 2 so as to create the maximum cooling efficiency. 3 to 8 times, and the cross-sectional area of the hot water cooling heat exchange part (5) is 250x250mm and the length is 1000mm, 1500mm, 2000mm is provided for the hot water cooling module (1) made to be used properly according to the cooling capacity, Provided are a cooling chamber heat exchange hot water cooler (39) and a method of manufacturing the hot water cooling module (1) manufactured as a basic unit.

The function of the hot water cooling module is that the hot water introduced into the upper hot water inlet 6 passes through the hot water dispersing device 7 and falls evenly on the upper chamber fixing plate 9. The hot water thus distributed comes into contact with the cooling chamber 2 of the upper chamber fixing plate 9, and the hot water flows down the surface of the cooling chamber by gravity and flows down the surface of the cooling chamber 2 while the suction fan ( 36 is cooled by contact with the indoor air 4 flowing in through the cooling chamber 2. The cooled water is collected through the lower chamber fixing plate 10 to the drip tray 12 and then discharged to the outside of the hot water cooling module through the cooling water outlet 13. Hot water absorbing filter (8) is inserted on the upper chamber fixing plate (9) which absorbs the water so that the hot water dropped to the upper chamber fixing plate (9) evenly contact with the chamber.

The suction fan 36 attached to the rear side of the hot water cooling module allows the indoor air to be constantly introduced under a constant static pressure through the cooling air inlet 43 of the cooling chamber heat exchange hot water cooler 39 so as not to be affected by external weather conditions. It was not.

Perforated stainless steel plates, aluminum or PVC plates. In order to spread the water introduced into the hot water inlet 6 of the hot water cooling module 1 evenly on the upper chamber fixing plate 9, the hot water dispersing apparatus with a stainless steel plate, aluminum or PVC plate with a hole of 1.0 to 5.5 mm in diameter ( 7) is used.

The following describes the manufacturing technology of the cooling chamber heat exchange hot water cooler components.

〈Cooling room production〉

Since the temperature change range of the water handled by the cooling chamber heat exchange hot water cooler 39 of the present invention ranges from room temperature (20 to 30 ° C.) to about 80 ° C., the cooling chamber 2 used in the cooling chamber heat exchange hot water cooler 39 has a temperature. It shall be a flame-resistant thread that is not affected by change and does not change in length, and should be internally decayed to prevent decay by mold or bacteria when wet. The yarn satisfying such conditions is suitable for a polyester yarn made of polyethylene (PE) or PE rope, and a steel rope made of stainless steel can also be used. Since PE also has a slight change in temperature, it was used after boiling at 100 ° C. for 1 to 2 hours before use in order to minimize the change in the thread length according to the change. After boiling at 100 ° C, the length of the dried polyester yarn or PE rope decreased by about 3.8%, and the polyester yarn or PE rope heat-treated in boiling water was 0.2 to 0.5 in elasticity when wet and dried. There was a difference of%. Such changes in the yarn may be so close as to allow the cooling chambers adjacent to each other to cross each other during the cooling of the hot water, and as much as possible when the hot water cooling heat exchanger 16 is manufactured, it is fixed to the upper and lower chamber fixing plates 9 and 10.

<Thread thickness and interval decision between thread and thread>

The maximum cooling efficiency of the cooling chamber heat exchange hot water cooler 39 of the present invention can be obtained by making the contact area between the cooling air and the hot water maximum. In order to maximize the contact area, a large number of cooling chambers 2 should be put in the cross-sectional area of the hot water cooling heat exchanger 16, and when the mistake is determined, the coarse thread should be used. However, in this case, when the cooling chamber 3 uses a dense and coarse thread, the thread and the thread come into contact with each other, which hinders the flow of cooling air and results in a decrease in the cooling effect as a result of reducing the contact area. Therefore, the cooling chamber 3 of suitable thickness should be arrange | positioned at appropriate intervals. The longer the cooling chamber 3 is, the more likely this contact phenomenon occurs. In order to determine the proper spacing of the cooling chamber, a thread with a length of 1500 and 2000 mm and a thickness of 1.5 and 3 mm is used to make a thread hole with different thread hole spacing according to the thread hole manufacturing method described in the production of upper and lower fixing plates. The cooling effect with varying intervals was tested. As a result, if the maximum thread surface area can be obtained without contact between the thread and the thread, the optimal distance between the thread and the thread on the line that is lined up in a straight line is 6 times the thread thickness, and the thread line spacing is It was when. At this time, the closest gap between the thread and the thread and the distance farthest apart can be calculated as shown in Fig. 2, and when the thread thickness is 2.5 mm, the closest gap is 7.8 mm and the longest gap (in the horizontal direction Thread and thread spacing) was 19.5 mm. Therefore, in the present invention, the closest interval between the cooling chamber and the cooling chamber is three times the thickness of the yarn, and the longest interval is eight times. The yarn surface area arranged in this way is constant regardless of the thread thickness. However, in order to lower the manufacturing cost, the number of holes must be reduced, so a thick thread should be selected, but a thick thread should be selected to a suitable thickness that does not interfere with the flow of air. In order to manufacture the upper and lower cooling chamber fixing plates 9 and 10 of the hot water cooling heat exchanger 16 in consideration of the influence of the thread thickness and spacing on the cooling effect, the thickness of the yarn is first determined, and accordingly, the thread hole spacing. And the number of thread holes is determined. In the present invention, when the upper and lower cooling chamber fixing plates 9 and 10 were manufactured according to the results of the examples, the yarns having a diameter of 2.5 mm were used, and the longest intervals and the closest intervals of the yarns and the threads were 20 and 8 mm, respectively.

〈Upper and Lower Thread Fixing Plates and Seal Separation / Stainless Steel Sheet Support Plates〉

As shown in FIG. 6, the upper and lower thread fixing plates 9 and 10 and the thread separating holding / stainless steel sheet support plate 11 were made of stainless steel plates, and were 250x250x5mm, respectively. The hole arrangement is arranged in a zigzag method as shown in FIG. 6A to maximize the cooling efficiency by making contact with the hot water going down the thread as the cooling air passes between the threads. The size of the thread hole was determined by changing the size of the thread hole and comparing the state where the thread enters the thread hole with the state where the water passes through the thread hole. The hole was 1.8 times the thread thickness, and the thickness was 1.5mm and 2.0mm. The thread holes of the 2.5 mm and 3.0 mm yarns were made to have diameters of 2.7 mm, 3.6 mm, 4.5 mm and 5.4 mm. In the arrangement of the holes shown in Fig. 6A, the interval between the thread holes along the horizontal thread holes was 6 times the thread thickness, and the distance between the thread hole center and the thread hole center was 6 times the thread thickness and the thread hole size (thread thickness).

Cooling water from the coolant outlet 13 of the cooling water storage tank through the coolant inlet 30 was to be collected directly to the coolant storage tank (28). The coolant collected in the coolant storage tank 28 was connected to the circulation pump 40 at the coolant outlet 31 of the coolant storage tank so that the coolant could be immediately used to cool the heat generating system. Cooling water replenishment inlet 32 that can be connected to the water so as to supplement the cooling water reduced by the steam at any time was installed.

<Ventilation doc production>

The cooling air, which is the indoor air (4) that has passed through the hot water cooling module (1), must be discharged to the outside because it contains water vapor. For this purpose, the cooling air must be discharged to the outside of the hot water cooling module (1). Ventilation duct 33 was produced as shown in Figure 8 so as to pass through the whole. The ventilation duct 33 is made to attach and detach the rear side of the hot water cooling module 1 so that the rear side of the hot water cooling module 1 can be attached and detached, and the flow of cooling air in the hot water cooling module 1 can be made smoothly, and the price is lower. In order to lower the temperature, the ventilation duct 33 may be attached to the center of the upper half of the hot water cooling module 1 by 45 degrees, and the cross-sectional area of the ventilation tube 35 may be 250x250 mm depending on the size of the cooling chamber heat exchange hot water cooler 39.

〈Method of manufacturing hot water cooling device according to cooling capacity〉

On the basis of the hot water cooling module (1), one or more hot water cooling modules (1) are linked to each other according to the cooling capacity of the heat generating system to manufacture a hot water cooling device (38) according to the hot water cooling capacity. The structure of the hot water cooling device 38 produced according to the hot water cooling capacity by allocating the hot water cooling module 1 is shown in FIG. 9. In the case where the hot water cooling module 1 is arranged in a straight line, that is, for example, when the hot water cooling device 38 is manufactured by using three hot water cooling modules 1, a 1 × 3 type is placed in a straight line (FIG. 9A). In case of using 6 pieces, the structure is made of 2x3 formula (2) in 2 lines of 3 pieces each, and in case of 12, 3x4 type (C) of figure 9 is used. Made of structure. In the method of coalescing, in consideration of the optimum cooling efficiency of the cooling air, the cooling air inlet is located in the rectangular side so that the maximum cooling effect can be obtained with the small amount of cooling air inflow. . In this way, the hot water cooling device 38 may be manufactured by combining a suitable number of the hot water cooling modules 1 in various assembling methods in consideration of the cooling capacity of the heat generating system.

When the above-described components are manufactured and installed, the cooling chamber heat exchange hot water cooler 39 of the present invention as shown in FIG. The main components of the cooling chamber heat exchange hot water cooler (39) is a hot water cooling device (38), a cooling water storage tank (28), a circulation pump (40), a suction fan (36) made by coalescing a hot water cooling module (1). , And other auxiliary elements included in the cooling chamber heat exchange hot water cooler (39) include a cooling water bypass valve, a flow meter, a hydraulic pressure gauge, an inlet water temperature thermometer, an outlet coolant temperature thermometer, a coolant supplement control valve, and a fan air flow control inverter. And so on. When the cooling chamber heat exchange hot water cooler (39) of the present invention is used in connection with a heat generating system, the cooling water pump lake (41) of the cooling chamber heat exchange hot water cooler (39) is connected to the cooling water inlet of the heat generating system and the cooling chamber heat exchange hot water cooler (39) of the hot water inlet hose 42 is connected to the hot water outlet of the heat generating system for easy use.

Next, a method of using the cooling chamber heat exchange hot water cooler 39, a performance, a cooling efficiency, a cooling capacity determining method, and the like will be described through examples.

<Example 1: How to use>

The cooling water pump hose 41 and the hot water inlet hose 42 of the cooling chamber heat exchange hot water cooler 39 are respectively connected to the cooling water inlet and the hot water outlet of the heat generating system, and the cooling water of the cooling water storage tank 28 is circulated pump (40). ), Remove the air in the cooling water circulation system of the heat generating system and start the heat generating system. In order to control the cooling rate of the heat generating system, the cooling water bypass valve connected to the outlet of the circulation pump 40 bypasses a part of the cooling water from the circulation pump 40 directly to the hot water inlet hose 42 and exits the heat generating system. After diluting with hot water, it is introduced into the warm water cooling device 38. The temperature of the hot water passing through the heat generating system is 50 to 80 ℃ and the inlet hot water of the hot water cooling device 38 diluted with cooling water is 40 to 45 ℃.

The purpose of the cooling water bypass is to control the amount of cooling water flowing into the heat generating system, and to minimize the cooling water loss due to the evaporation of water vapor during the hot water cooling process. While the hot water passes through the hot water cooling heat exchange part 5 of the hot water cooling device 38, it comes into contact with the indoor air 4 introduced by the suction fan 36 through the cooling air inlet 43 to which the air filter screen is attached. As it cools down, the cooling water becomes about the same as the room temperature and flows into the cooling water storage tank 28. Since the cooling water is evaporated into water vapor and discharged to the outside while the cooling chamber heat exchange hot water cooler 39 is operated, the amount of cooling water decreases according to the operating time, and the amount of cooling water is supplemented to the cooling water level in the cooling water storage tank 28. It is detected by the water control valve to allow the coolant to be automatically supplied to the coolant storage tank 28 through the coolant supplement water inlet 32, the coolant of the coolant storage tank 28 is generated again by the circulation pump 40 It enters the system and cools the heat generating system. As the circulation of the cooling water continues, the heat generating system is appropriately cooled to prevent damage to the heat generating system due to heat or to stop operation. <Example 2: Determination of the number and size of injection holes of the hot water dispersing device> Hot water cooling heat exchanger 16 and hot water shown in FIGS. 3 and 4 using acrylic plates and PVC hole plates to determine the number and size of distribution per unit area of the hot water dispersion plate dispersion holes of a hot water dispersing device 7 An experimental apparatus such as a dispersing apparatus 7 is manufactured, and a hot water dispersing experiment apparatus is installed on the hot water cooling heat exchange experiment apparatus. The flow rate through the hole and flowing into the upper portion 14 of the hot water cooling heat exchanger was observed to determine the distribution number and size of the hole. In order to determine the number of hole distribution of the hot water dispersing plate 21, each PVC hole plate having 4, 8, 12, 14, 20 holes per unit area of 2.5 mm in diameter was used. 21), and observed the dispersion of water introduced into the hot water dispersion tester. As a result, the hot water dispersing device having a small number of holes per unit area, that is, a small hot water dispersing plate attached to the hot water dispersing device does not flow out of the hot water dispersing device to the upper portion 14 of the hot water cooling heat exchanger. This is a phenomenon (meaning that more holes are required), and the hot water dispersing device with the hot water dispersing plate with a large number of holes has flowed into the upper part of the hot water cooling heat exchanger through a portion of the hot water dispersing plate. This phenomenon is inefficient for the hot water treatment because it exhibits a phenomenon of not evenly dispersing in the upper part of the cooling heat exchanger. Therefore, the water passing through the hot water dispersion plate 21 at a constant flow rate should be spread evenly over the top of the hot water cooling heat exchanger and flow out without accumulation. Therefore, in order to satisfy these dispersion conditions, a suitable water per unit area of the hot water dispersion plate 21 is required. The hot water dispersion hole is required, and the proper number determined through this experiment was 8 per 25cm ² . In the case of dispersing hot water using such a hot water dispersion plate, if the flow rate is changed, an inefficiency phenomenon as described above may occur. Thus, by adjusting the size of the hot water dispersion hole to avoid inefficiency distribution according to the flow rate. To this end, the hole size was changed from a diameter of 1mm to 5mm, the inflow of water was increased from a low flow rate, the dispersion phenomenon was well observed, and the results are shown in FIG. 11. When the water flowing into the hot water dispersing device 7 passes the entire area of the hot water dispersing plate 21, the minimum water pressure was 0.03 to 0.05 kgf / cm ² , and the flow rate at this time is the total area of the hot water dispersing device 7. Since the minimum flow rate of the flow rate passes, the flow rate when such a condition is reached is determined as the minimum applicable flow rate of the hot water distribution plate 21 and is shown in FIG. According to Figure 11 in the case of hot water dispersion plate 21 punched in a diameter of 1.5mm, the minimum flow rate is 1ℓ / min, so that the flow rate must be applied more than this flow rate, even if 2mm / 2ℓ / min or more, 3mm or more, 5mm / min or more, 5.5mm or more, 14l / min or more, respectively, the maximum flow rate flowing into the hot water dispersing device (7) is the water pressure required by the application system ( In case of high temperature sintering furnace, it can be used up to 3kgf / cm ² ). Dispersing a large amount of hot water using a small hole hot water distribution plate should be avoided because unnecessary water pressure increases to increase the load on the circulation pump, in consideration of this phenomenon, the hole size of the hot water distribution plate 21 The condition for determining the size should be determined by the hole size of the hot water distribution plate 21 capable of efficiently processing the lowest flow rate. For example, when the minimum flow rate is 9 l / min, the hole size of the hot water dispersion plate 21 may be determined to be 4 mm from Fig. 11. <Example 3: Cooling effect by thread thickness> In order to grasp the cooling effect by thread thickness Experiment using hot water cooling module (1) shown in Figure 1 on the scale of 250x250x1500mm using the conditions (8 holes of 2.5mm diameter per 25cm ² ) of the hot water dispersion plate 21 determined through Example 2 Was performed. The upper and lower thread fixing plates (9, 10) of the hot water cooling module (1) having a thickness of 1.8, 2.5, and 3.5 mm are made and replaced, and the hot water cooling rate in each case, that is, the difference between the inflow water temperature and the outflow water temperature The results are shown in FIG. At this time, the inflow amount was 5 L / min, the air flow was 10 and 35 m ³ / min. As can be seen from FIG. 12, the cooling rate is better than that of the other 2.5 mm thick yarns among the three yarn thicknesses tested. This phenomenon is because the thin thread (1.8mm thick) has less surface area than 2.5mm thread, so the contact area between air and water is less and the cooling effect is small.In the case of 3.5mm thread, the thread is thick It is believed that this is because the spacing is small so that contact between adjacent threads may occur, thereby preventing air flow or reducing the contact area between air and water. Therefore, the thickness of the thread used in one hole should be used of the appropriate thickness, in the present invention, the thickness of the thread is 2.5mm in diameter and the thread hole of the upper and lower fixing plates (9, 10) is 1.8 times the diameter of the thread 4.5 Example 4 Cooling Effect According to Length of Hot Water Cooling Heat Exchange Site The cooling chamber heat exchange hot water cooler according to the present invention has a contact time with cooling air when hot water is cooled while flowing down the hot water cooling heat exchange site (5). The longer the cooling effect, the better the cooling effect, but because it is cooled by the air around the indoor air or the hot water cooling system, it cannot be cooled below the air temperature around the indoor air or the cooler. Therefore, the cooling effect is more than the proper length of the hot water cooling heat exchange part (5). It is not big. Therefore, in order to lower the manufacturing cost of the cooling chamber heat exchanger hot water cooler 39, it is necessary to determine the appropriate length. To this end, the experimental apparatus used in Example 3 was used, and the thread thickness was 2.5 mm in diameter, the inflow amount was 5 l / min, and the air volume was 10 and 36 m ³ / min. The inlet water was cooled while changing. The temperature gradient according to the length of the hot water cooling heat exchange part 5 is shown in FIG. 13 by measuring temperatures at positions of 50, 100, and 150 cm from the top of the hot water cooling heat exchange part. As can be seen from FIG. 13, the inflow of hot water is rapidly cooled to 50 cm, and then the cooling degree is weak until 100 cm, and after 100 cm, the cooling degree is gentle. Therefore, the length of the hot water cooling heat exchange part 5 required to cool the hot water below 50 ° C. is sufficient to be 100 cm, and 150 cm is required to cool the hot water further.

<Example 5: Cooling efficiency of hot water cooling module>

The cooling efficiency of the hot water cooling module 1 was determined by installing the 250x250x1500 mm hot water cooling module 1 produced by combining the results of the above examples in conjunction with a 650 liter hot water storage tank and a cooling water collection tank. 500 liters of hot water in the hot water storage tank was introduced into the hot water cooling module with a circulation pump at a flow rate of 5 and 8 l / min, and the cooling water passing through the hot water cooling module was collected in the cooling water collection tank. The temperature of the injection hot water was 24 ° C. to 60 ° C. to determine the cooling efficiency of the hot water cooling module 1 by the temperature difference between the hot water temperature and the cooling water temperature. The flow rate of cooling air for cooling hot water was divided into upper and lower loads to check the effect on the air inflow rate. The inflow amount of the cooling air used was 4, 20 and 24㎥ per minute, respectively. The results are shown in FIG. When the coolant inflow temperature of the hot water cooling module 1 is 44 ° C., the hot water passing through the hot water cooling module 1 is cooled to 22 ° C. from FIG. 14 when the air volume of 4 m 3 / min and the cooling water flow rate of 5 l / min are used. It can be seen that, when the flow rate is the same and the air flow rate of 24㎥ / min using 44 ℃ hot water is cooled to 18 ℃. It can be seen that the cooling water temperature is 25 ° C. when the cooling water flow rate is increased to 8 L / min and the air volume is maintained at 24 ㎥ / min. Therefore, it can be seen from FIG. 14 that the hot water cooling module 1 of the present invention has a cooling efficiency of 42 to 75% because the hot water that is 24 to 60 ° C. is cooled to 10 to 39 ° C. FIG.

At this time, the room temperature was 21 ℃, and the coolant temperature cooled by the cooling air at room temperature was different from the room temperature. The coolant itself maintained a temperature lower than the room temperature (when the room temperature is 21 ℃, the coolant temperature is 18 ° C.), due to the chilling effect when blowing air. As a result of the test of the chilling effect of the air, when the indoor air is 28 ℃, the temperature of the indoor water was 25.2 ℃, when the water was passed through the hot water cooling module (1) without operating the ventilator temperature was 24.0 ℃, The outflow water temperature at the time of cooling by the air volume of 24m <3> / min was cooled to 20.0 degreeC. That is, the chilling effect of the room air of 28 degreeC was 4 degreeC.

<Example 6: Relationship between cooling capacity of hot water cooling module and cooling chamber heat exchange hot water cooler>

Cooling water inflow of the hot water cooling module (1) of the present invention to use 3 to 15ℓ / min, the optimum inflow is 10ℓ / min, the air flow of the indoor air flowing into the hot water cooling module (1) is 4 to 24㎥ / min can be used, the optimum air volume is 15㎥ / min, when the room temperature is 21 ℃ can cool the hot water of 48 ℃ to 18 to 22 ℃.

Based on the cooling efficiency of the hot water cooling module 1 as described above, the number of hot water cooling modules 1 according to the cooling capacity of the cooling chamber heat exchange hot water cooler can be determined. As the hot water inflow increases, the number of the hot water cooling modules 1 increases in proportion, and the air volume is proportional to the area of the cooling air inlet 43 of the hot water cooling module 1. Therefore, when six hot water cooling modules 1 are united in two rows of three (B) in FIG. 10, the optimum amount of hot water is 60 L / min, and can be processed up to 90 L / min. Since the indoor air inlet corresponds to twice as much as the cooling air inlet 43 of the hot water cooling module 1, the air flow rate is 8 to 48 ㎥ / min. When 12 hot water cooling modules (1) are united in 3x4 (FIG. 10 (C)), the hot water inflow area is 12 times higher than that of the hot water cooling module (1), and the area of the cooling air inlet is 3 times the maximum. It is 180 L / min, and air volume is 12-72m <3> / min.

Since the cooling chamber heat exchange hot water cooler provided by the present invention can be manufactured in various sizes, it can be attached to various heat generating systems requiring mathematical cooling, so the installation cost is low and a separate outdoor installation place is unnecessary, and the indoor installation is possible. As a result, it is possible to operate continuously in winter, and also to reduce the additional operation cost according to the special operation for preventing the freezing and freezing of the existing cooling tower and the replacement operation of other cooling systems. 30 to 100kg), less than 1 ton of cooling water is used, and only the quantity reduced to steam to replenish the water saving effect is great.
