Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cooling tower with an automatic cleaning device. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate excess heat generated in industry or refrigeration and air conditioning to lower the water temperature by using water as a circulating coolant and dissipating it into the atmosphere to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] During daily use, cooling towers are exposed to the air, which contains a lot of suspended matter, dust, and impurities that adhere to the air filter. As the amount of debris attached to the air filter increases, the air volume at the air inlet decreases, affecting the cooling effect of the cooling tower. A cleaning device for a cooling tower and a cooling tower with authorization publication number CN base 219483490 U are described. Cleaning members are installed at the air inlet and outlet, and a driving mechanism drives the cleaning members to reciprocate between the air inlet and outlet. This allows the cleaning members to absorb debris at the air inlet and remove it at the air outlet, thereby achieving the cleaning purpose.

[0004] However, the above-mentioned cleaning device is entirely covered at the air inlet and outlet positions, which inevitably affects the air circulation efficiency of the air inlet and outlet, and affects the overall cooling effect of the cooling tower; in addition, if the debris is only desorbed by the air circulation at the air outlet, there is a possibility that the debris will be stuck in the pores of the cleaning part and fail to be desorbed, resulting in poor cleaning effect.
