[0027] Please refer to Figures 1 to 4The utility model provides a kind of high-efficiency heat exchange tube device for coil evaporative condenser, including placing box 1, fixedly connected with installation frame 2 on the inner wall of placing box 1, array fixedly connected with coarse diameter evaporative condensing coil 3 on installation frame 2, fixedly connected with fine diameter evaporative condensing coil 4 at the end of coarse diameter evaporative condensing coil 3, one end fixedly connected with refrigerant air inlet 5 of coarse diameter evaporative condensing coil 3 and extending to the outside of placing box 1, fixedly connected with refrigerant drop liquid outlet 6 of fine diameter evaporative condensing coil 4 and extending to the outside of placing box 1, fixedly connected with spraying mechanism 7 at the position of placing box 1 above coarse diameter evaporative condensing coil 3, fixedly connected with circulation mechanism 8 at the position of placing box 1 inner wall away from coarse diameter evaporative condensing coil 3.

[0028] High-temperature refrigerant gas enters coarse diameter evaporative condensing coil 3 by refrigerant air inlet 5, and the spraying mechanism 7 is arranged to spray cooling water on coarse diameter evaporative condensing coil 3, heat exchange is carried out, so that the phase change condenses into refrigerant liquid, and the flow rate is increased in fine diameter evaporative condensing coil 4, so that the refrigerant liquid rapidly passes through fine diameter evaporative condensing coil 4, and then returns to the evaporator through refrigerant drop liquid outlet 6, the spraying mechanism 7 is arranged to spray cooling water on most parts of coarse diameter evaporative condensing coil 3, the contact area of cooling water and coarse diameter evaporative condensing coil 3 is increased, so that the high-temperature refrigerant gas in coarse diameter evaporative condensing coil 3 can exchange heat with cooling water more quickly, so as to accelerate the efficiency of refrigeration, and the circulation mechanism 8 is arranged to enable the sprayed cooling water to be sprayed on coarse diameter evaporative condensing coil 3 again through the spraying mechanism 7, so as to improve the utilization rate of cooling water.

[0029] Please refer to Figure 2 and Figure 3 , the spraying mechanism 7 includes a first spray pipe 9 fixedly connected to the inner wall of the placing box 1, a first spray head 10 is fixedly connected to the first spray pipe 9, a water storage tank 11 is arranged at the position of the placing box 1 below the fine diameter evaporative condensing coil 4, a water inlet pipe 12 is fixedly connected to one end of the first spray pipe 9 extending to the outside of the placing box 1, a pump 13 is fixedly connected to the water inlet pipe 12, the other end of the pump 13 is connected to the water storage tank 11 through a pipeline, and a spraying assembly 14 is fixedly connected to the inner wall of the placing box 1 for spraying below the coarse diameter evaporative condensing coil 3.

[0030] Please refer to Figure 3 , the spraying assembly 14 includes a fixed pipe support 15 fixedly connected to the inner wall of the placing box 1, a second spray pipe 16 is rotatably connected to the fixed pipe support 15, a second spray head 17 is fixedly connected to the second spray pipe 16, and the spraying direction of the second spray head 17 is inclined to the second spray pipe 16.

[0031] The cooling water in the water storage tank 11 is pumped by the pump 13 through the pipeline into the water inlet pipe 12, and flows into the first spray pipe 9 through the water inlet pipe 12, and is sprayed from the first spray head 10 to cool the high-temperature refrigerant gas in the continuous wave-shaped thick-diameter evaporative condensing coil 3, and to speed up the heat exchange efficiency of the high-temperature refrigerant gas. At the same time, the cooling water flows from the first spray pipe 9 into the fixed pipe support 15, and then is sprayed from the second spray head 17 on the second spray pipe 16. The pipe diameter of the second spray pipe 16 is smaller than that of the first spray pipe 9, so that the flow rate of the cooling water through the second spray pipe 16 is faster, and the flow rate of the cooling water sprayed from the second spray head 17 is faster. The cooling water can be sprayed onto the thick-diameter evaporative condensing coil 3 below the first spray head 10, so as to increase the contact area of the cooling water and the thick-diameter evaporative condensing coil 3, increase the heat exchange speed, and thus speed up the refrigeration efficiency. At the same time, the water sprayed from the second spray head 17 contacts the thick-diameter evaporative condensing coil 3, and generates a reaction force on the second spray pipe 16, so that the second spray pipe 16 rotates relative to the fixed pipe support 15, thereby increasing the spraying range of the cooling water, further increasing the contact area of the cooling water and the thick-diameter evaporative condensing coil 3, and increasing the heat exchange speed.

[0034] The cooling water falling from above the placing box 1 will fall on the partition plate 18, the partition plate 18 blocks the falling cooling water and falls into the water storage tank 11 through the through port, for recycling of the cooling water, at the same time, the partition plate 18 separates the fine-diameter evaporative condensing coil 4 and the coarse-diameter evaporative condensing coil 3, the temperature of the cooling water after heat exchange will rise, and the temperature of the fine-diameter evaporative condensing coil 4 is relatively low, so as to avoid the cooling water after heat exchange from contacting the fine-diameter evaporative condensing coil 4 and prevent the cooling water after heat exchange from transferring heat to the fine-diameter evaporative condensing coil 4, thereby ensuring the refrigeration effect, at the same time, the motor 22 is started, the motor 22 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the fan blade 21 to rotate, the air in the placing box 1 flows faster, the heat is taken out of the placing box 1, thereby improving the heat exchange effect, and the fan blade 21 drives the air flow to increase the residence time of the cooling water on the partition plate 18, so as to cool the cooling water and ensure the subsequent use effect.

[0035] Please refer to Figure 3 , the fixed pipe support 15 is hollow and connected with the first spray pipe 9, the fixed pipe support 15 is connected with the second spray pipe 16, the cooling water in the first spray pipe 9 flows into the second spray pipe 16 through the fixed pipe support 15, and then flows out of the second spray head 17.

[0036] Please refer to Figure 1 , the placing box 1 is fixedly connected with the air outlet pipe 23 at the upper end, so that the cooling water vapor evaporated on the coarse-diameter evaporative condensing coil 3 can flow out of the air outlet pipe 23, thereby enabling the heat to flow out of the air outlet pipe 23.

[0037] Please refer to Figure 2 , the placing box 1 is fixedly connected with the air inlet pipe 24 at the side wall, the air inlet pipe 24 is located below the partition plate 18, the external air flows into the air inlet pipe 24, thereby ensuring that the air in the placing box 1 can circulate, and the location below the partition plate 18 can avoid the falling cooling water from flowing out of the air inlet pipe 24.

[0038] Please refer to Figure 2 , the coarse-diameter evaporative condensing coil 3 is provided with a refrigerant gas collecting bag 25 between the refrigerant gas inlet 5, the high-temperature refrigerant gas reaches the refrigerant gas collecting bag 25 from the refrigerant gas inlet 5 and is uniformly distributed into the coarse-diameter evaporative condensing coil 3.

[0039] Please refer to Figure 2 , the fine-diameter evaporative condensing coil 4 is fixedly connected with a refrigerant liquid collecting bag 26 between the refrigerant liquid inlet 6, so that the refrigerant liquid rapidly passes through the fine-diameter evaporative condensing coil 4, flows into the refrigerant liquid collecting bag 26, and then flows out through the refrigerant liquid inlet 6.
