Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to an antifreeze type cooling tower. 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 reduce the water temperature. It produces steam by exchanging heat between water and air flow, and the steam evaporates and takes away the heat, thereby achieving 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 and reduce the water temperature. A cooling tower is a comprehensive product that integrates aerodynamics, thermodynamics, fluid mechanics, chemistry, biochemistry, materials science, processing technology, and other disciplines.

[0003] In some high-latitude cold areas, due to the low external ambient temperature, the internal water circulation system of the cooling tower is prone to freezing when it is working. After the water freezes, it will cause the water pump to be blocked, the inside of the cooling tower to freeze, and even further cause the water pump to burn out, which will cause the cooling tower to be unusable, causing irreparable economic losses to users. Therefore, we propose an antifreeze cooling tower to solve the above-mentioned problems. Utility Model Content
