Problems solved by technology

[0002] In the related art, due to the low surface temperature of the heat exchanger during the operation of the heat exchange system, condensed water may be generated on the surface when the temperature is lower than the dew point, and frost may even form on the surface, which will affect the heat exchange efficiency of the heat exchanger. The heat exchanger requires dehumidification treatment. In related technologies, lithium salt desiccants or silica gel hygroscopic materials are used for the moisture absorption treatment on the surface of the heat exchanger, but lithium salt desiccants are not friendly to metal surfaces, and silica gel hygroscopic materials are not sticky, so additional The adhesive makes it bond to the surface of the heat exchanger. In summary, the heat exchanger in the related art needs to be improved

Abstract

The invention discloses a micro-channel heat exchanger comprising heat exchange tubes and fins, wherein at least a part of the surface of each heat exchange tube and / or a part of the surface of each fin are / is covered with hygroscopic colloid, the pH of the hygroscopic colloid ranges from 6 to 8, the hygroscopic colloid has adhesion to the metal surface, the hygroscopic colloid can directly cover at least a part of the surface of the heat exchanger, and the hygroscopic colloid comprises zinc oxide gel.

Description

technical field [0001] The present application relates to the field of heat exchange, in particular to a heat exchanger. Background technique [0002] In the related art, due to the low surface temperature of the heat exchanger during the operation of the heat exchange system, condensed water may be generated on the surface when the temperature is lower than the dew point, and frost may even form on the surface, which will affect the heat exchange efficiency of the heat exchanger. The heat exchanger requires dehumidification treatment. In related technologies, lithium salt desiccants or silica gel hygroscopic materials are used for the moisture absorption treatment on the surface of the heat exchanger, but lithium salt desiccants are not friendly to metal surfaces, and silica gel hygroscopic materials are not sticky, so additional The adhesive makes it adhere to the surface of the heat exchanger. In summary, the heat exchanger in the related art needs to be improved. Conte...
