Abstract

The invention relates to a heat dissipation system of an electric control box, a heat dissipation control method and an air conditioner. The heat dissipation system of the electric control box comprises an air conditioner fresh air section; the first air supply pipeline is connected to the air conditioner fresh air section; an air conditioner air supply section; the second air supply pipeline is connected to the air conditioner air supply section; and an air outlet of the drainage pipeline is connected to the electric cabinet, and an air inlet of the drainage pipeline selectively communicates with the first air supply pipeline and the second air supply pipeline. The heat dissipation control method comprises the steps that the operation mode of the air conditioner is detected; and according to the operation mode, a drainage pipeline for controlling the electric control box to selectively communicate with a first air supply pipeline of the air conditioner fresh air section and a second air supply pipeline of the air conditioner air supply section, so that the electric control box dissipates heat. The air conditioner comprises the heat dissipation system of the electric cabinet. According to the heat dissipation system of the electric control box, the heat dissipation control method and the air conditioner, the air volume of the air conditioner fresh air section or the air conditioner air supply section is distributed to the electric control box, and overall uniform heat dissipation of the electric control box is facilitated.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a heat dissipation system of an electric control box, a heat dissipation control method, and an air conditioner. Background technique [0002] With the continuous development of industrial technology, people have higher and higher requirements for air-conditioning units. The protection level of the electric control box of the air-conditioning unit is getting higher and higher, and the sealing of the electric control box is getting better and better, and the heat dissipation of the electric control box has become the primary problem. In order to solve the heat dissipation problem of the electric control box, the condensed refrigerant pipe is directly attached to the surface of the electrical components to be radiated for heat conduction and heat exchange. Only local heat exchange is possible, and the electric control box is prone to failure due to uneven local h...
