Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a blower-type cooling tower with a whitening device. 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 to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus dissipating the waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] Most existing cooling towers place the fan at the top, drawing air from inside the tower to create negative pressure, thus allowing the air to come into contact with the liquid to be cooled. However, due to the multiple air intakes inside the cooling tower, the amount of air in contact with the liquid is limited, resulting in a generally poor cooling effect.

[0004] The fan is placed on top of the cooling tower, which is inconvenient to maintain. Moreover, the high center of gravity can easily cause the cooling tower to be unstable. A large-power fan is required to generate negative pressure inside the cooling tower, resulting in high energy consumption. In addition, the amount of air in contact with the liquid to be cooled is limited, so the cooling effect is generally average. Utility Model Content
