In addition, the equipment using this solution has a relatively large amount of refrigerant filling, and the evaporated cooling water is not collected, which causes a waste of water resources.

[0013] Beneficial effects:

[0014] 1. The novel evaporative heat exchange device is provided with a corrugated tube and the heat exchange tube is distributed with a slope of 4%. The corrugated tube can make the condensed liquid generate a small vortex at the arc-shaped bend of the heat exchange tube, so that the condensed liquid forms a jet effect and a throttling effect; the heat exchange tube is distributed with a slope of 4%, so that the inertial force of the fluid will increase due to the gravity, thereby increasing the flow rate of the refrigerant in the tube, that is, the Reynolds number of the heat exchange medium increases, and the overall heat transfer coefficient of the heat exchange component will also increase accordingly. At the same time, the liquid flows along the slope direction due to the gravity, which can reduce the thickness of the liquid film in part of the heat exchange tube, reduce the heat transfer resistance of the heat exchange tube, and enhance the heat exchange. Under the premise of the same heat exchange amount, the area of ​​the heat exchange tube can be reduced, and the manufacturing cost of the heat exchange component can be effectively reduced. In addition, the use of the 4% slope heat exchange tube can reduce the refrigerant filling amount by about 7% to 13%, and the refrigerant filling amount of the ammonia refrigeration system is effectively reduced, which can fundamentally reduce the danger of using the refrigerant.

The fan assembly discharges the evaporated gas into the interior of the gas delivery pipe, and then enters the interior of the cylinder, and then passes through the horizontal perforations of the circular honeycomb heat exchange block. During the spraying assembly, the cooling water is delivered to the connecting pipe. The cooling water then enters the interior of the cylinder, and then passes through the vertical perforations of the circular honeycomb heat exchange block. In this way, the cooling water cools the circular honeycomb heat block, so that the evaporated gas in the horizontal perforations condenses into water. Finally, the cooling water and the condensed water enter the delivery pipe, and then enter the interior of the water collection assembly from the delivery pipe, thereby improving the utilization rate of water resources.
