Air conditioner electric control module cooling device and air conditioner outdoor unit

Abstract

The invention belongs to the field of air conditioners, particularly relates to a cooling device of an air conditioner electronic control module and an air conditioner outdoor unit, and aims at solving the problem that in the prior art, because of hindering of an air duct of a cooler, heat exchanging is not sufficient. In order to solve the problem, in the cooling device of the air conditioner electronic control module, the electronic control module is arranged in the air conditioner outdoor unit; the cooling device comprises a cooler arranged in the electronic control module in a matched manner; the cooling device further comprises a bypass air duct communicating an air outlet of the air conditioner outdoor unit with the cooler; and in the air conditioner running process, at least part of airflow at the position of the air outlet of the air conditioner outdoor unit can enter the bypass air duct, so that the cooler can be cooled. Due to the arrangement of the bypass air duct, according to the technical scheme, the cooler can be cooled by means of the airflow at the position of the air outlet of the outdoor unit, and the cooling effect of the air conditioner electronic control module is substantially improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a cooling device for an electric control module of an air conditioner and an outdoor unit of the air conditioner. Background technique [0002] With the development of power electronics technology, more and more circuits are integrated on unit components, and the corresponding heat flux increases rapidly. In order to ensure the normal working efficiency of components, it is necessary to improve and improve their cooling methods. It poses new challenges for its efficient heat dissipation. In the field of air-conditioning technology, the heat dissipation problem of the electronic control module on the air-conditioning has become more and more severe, and has become a problem restricting the development of the air-conditioning industry. For the heat dissipation problem of the air conditioner electronic control module, the current main solutions are as follows: ...
