Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger drying, in particular to a drying device for an air-conditioning heat exchanger. Background Art

[0002] An air conditioning heat exchanger is a device used to transfer heat, usually used to cool indoor air or objects. It works by establishing heat exchange between refrigerants. During use, the heat exchanger will frequently come into contact with water and moisture. First, the heat exchanger is usually located at the inlet and outlet of the indoor air circulation, and these locations usually have high humidity. Secondly, due to the working principle of the air conditioning system, the refrigerant releases heat when flowing in the heat exchanger, which will cause the temperature of the surrounding air to increase, thereby increasing the humidity. If the drying operation is not performed during the production process, moisture and humidity may remain on the surface of the heat exchanger, causing the heat exchanger to rust;

[0003] Most of the drying of heat exchangers is done by blowing hot air onto the surface of the heat exchanger. Some areas may receive too much heat while other areas receive insufficient heat, causing uneven heating of the heat exchanger and affecting the drying effect.

[0004] In order to solve the above problems, the present application proposes a drying device for an air conditioner heat exchanger. Utility Model Content
