Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water circulation cooling tower. Background Art

[0002] A cooling tower is a cooling device. The cooling tower uses water as a circulating refrigerant, absorbs heat from a system and discharges it into the atmosphere. The water is used to absorb the heat and turn it into hot water. The hot water is then brought into contact with the air flow to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve the purpose of heat dissipation. Announcement No.: CN215295881U discloses a water circulation cooling tower, including a cooling tower body. The top of the cooling tower body is provided with an exhaust port for discharging hot air. The cooling tower body is equipped with a suction structure for extracting hot air. The outside of the exhaust port is surrounded by a retaining structure for blocking droplet splashing. The present application has the effect of reducing the occurrence of droplet splashing and contaminating the equipment. However, the above technology does not filter the discharged water during use, so that the particulate impurities and ionic impurities in the water will form scale in the cooling tower, which affects the use of the cooling tower, so it needs to be improved.
