Problems solved by technology

[0003]1. The tooth-shaped aluminum heat sink is large in size, requiring a large installation space for the air conditioner electrical box. Good heat dissipation, so the location of the air-conditioning electrical box to install the tooth-shaped aluminum heat sink must consider ventilation and waterproofing, which increases a lot of process steps and material costs;
[0004]2. The heat dissipation effect in summer is not ideal, especially in the hot summer in the southern region, when the air conditioner is frequently used to cool down, the power module of the air conditioner unit and the high-power inverter compressor drive The heat dissipation effect of the module and the high-power variable frequency fan drive module is not good, which affects the normal operation of the air conditioner. In severe cases, it will cause the air conditioner to malfunction, reduce the stability of the air conditioner and shorten the service life.

Abstract

The invention provides a flat-pipe microchannel aluminum radiator which comprises an aluminum plate and a thermal insulation layer fixed on an air conditioner box, wherein a flat-pipe microchannel heat exchanging pipe is arranged between the aluminum plate and the thermal insulation layer and is of a hollow pipe structure; and the cavity of the flat-pipe microchannel heat exchanging pipe is internally provided with a heat exchange grill. The flat-pipe microchannel aluminum radiator disclosed by the invention is reasonable in structure design, reduces radiator volume while enhancing heat radiating area, effectively controls and recycles heat and improves radiating efficiency during air conditioner running.

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...
