Description

technical field

[0001] The invention relates to a radiator for an air conditioner, in particular to an aluminum radiator for an air conditioner. Background technique

[0002] At present, the air-conditioning power supply modules, high-power variable frequency compressor drive modules and high-power variable frequency fan drive modules on the market usually use toothed aluminum heat sinks for heat dissipation. The tooth-shaped aluminum heat sink is installed outside the air conditioner electrical box. In order to facilitate heat dissipation, the tooth-shaped aluminum heat sink must be exposed to the external environment to ensure direct contact with the flowing air to improve heat dissipation efficiency. Therefore, the installation and use of the tooth-shaped aluminum heat sink requires complex waterproof measures for the air-conditioning electrical box, and also puts forward high requirements for the installation process of the air-conditioning electrical box in the air-con...
