Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically to a cooling tower with a de-icing structure. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere in order to lower the water temperature.

[0003] When the cooling tower is in use, cold air enters through the air inlet to exchange heat with the water sprayed by the spray pipes, thereby cooling the hot water.

[0004] Because some cold water or moisture adheres to the louvers inside the cooling tower, ice easily forms on the louver surface when the weather is cold and the outside temperature is low. If the ice is not removed in time, large areas of ice can block the air inlet. When the air inlet is blocked by ice, the air intake area is affected, the amount of air entering is reduced, and the cooling effect is poor. Therefore, it is urgent to design a cooling tower with an ice removal structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling tower with a de-icing structure to overcome the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:
