Description

Technical Field

[0001] The invention relates to the field of cooling towers, in particular to a high-efficiency cooling tower with uniform water distribution and steady flow. 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 heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] The existing cooling tower generally includes a tower body, a water distributor, a water collection tank and a water spray filler. The high-temperature water with a lot of heat is sprayed on the water spray filler through the water distributor to exchange heat with the air. The low-temperature cooling water after heat exchange enters the water collection tank, and the humid hot air is discharged from the tower body. The above conventional cooling tower has the following problems in actual application:

[0004] 1. The water distributor can only ensure that the top of the water filling can be sprayed evenly. Once the water filling is too high, it is difficult to ensure that the middle and lower parts can also receive uniform spraying;

[0005] 2. After long-term use, scale easily accumulates on the surface of the water-spraying filler;

[0006] The above problems will seriously affect the uniformity of water distribution and the stability of water flow, thereby affecting the cooling effect.
