[0002] Coal chemical industry refers to the process of using coal as raw material and chemically processing it into gaseous, liquid, and solid fuels and chemicals. In the actual process of coal chemical industry, cooling towers are used to cool the chemical substances in order to better control the reaction rate and product quality. Cooling towers are devices that use water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature.

[0003] This existing technology transports coal chemical fluid media through cooling copper pipes, and water sprayed from spray heads washes the cooling copper pipes and cooling fins. The water absorbs heat from the cooling copper pipes and cooling fins, thereby cooling the coal chemical fluid media. While this existing technology can cool the coal chemical media, it has certain limitations in practical implementation. In practice, the cooling fins are arranged horizontally in sequence, and the large area of ​​the fins obstructs airflow, resulting in slower discharge of the hot air after heat exchange. This affects the rate of heat loss from the tower, thus leading to low heat exchange efficiency. Utility Model Content
