Disclosed are air conditioner electric cabinet heat dissipation structure and air conditioner

Abstract

The invention provides an air conditioner electric control box heat dissipation structure and an air conditioner, the air conditioner electric control box heat dissipation structure comprises a heat exchanger and an electric control box, a shell of the electric control box is provided with a radiator with a closed heat dissipation loop, and the closed heat dissipation loop extends into a heat dissipation air duct of the air conditioner. The invention provides an air conditioner electric cabinet heat dissipation structure and an air conditioner. A radiator of the air conditioner electric cabinet is connected with the last section of U-shaped pipe of the condenser to form a closed radiating loop filled with a refrigerant; the section of U-shaped pipe is independent from other pipelines of the condenser; a refrigerant releases heat in a U-shaped pipe in an upper-layer condenser of the pipeline system and dissipates heat through condenser fins, and absorbs heat in a pipeline in a radiatorof a lower-layer electric cabinet; the electric cabinet heat dissipation system is separated from the complete machine refrigeration and heating system without heat dissipation through a refrigerant pipeline of the complete machine system, so that the electric cabinet heat dissipation system is not influenced by the working state of the complete machine system, and the cost of the complete machineis reduced; meanwhile, the structure needs fewer pipelines, and is simpler in structure and higher in reliability and practicability.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of an air conditioner electric control box, and more specifically relates to a heat dissipation structure of an air conditioner electric control box and an air conditioner. Background technique [0002] At present, the heat dissipation scheme of the electric control box of the air conditioner is mainly air-cooled heat dissipation or system refrigerant pipe heat dissipation. The use of air-cooled heat dissipation can satisfy the electric control box with low heat generation. For the frequency conversion unit industry, the system refrigerant pipe heat dissipation is generally used. Through the main road or bypass pipe of the system to the radiator of the electric control box, the refrigerant flows through the pipe to dissipate heat. This structural design makes the heat dissipation of the electric control box highly dependent on the refrigerant circulation of the whole system. Once the refr...

[0003] The present invention solves the problem that the heat dissipation structure of the existing air-conditioning electric control box is highly dependent on the refrigerant cycle of the whole machine system through the main circuit of the system refrigerant pipe or the refrigerant flowing through the electric control box, and is easily affected by the blockage of the system refrigerant pipe. The life of control box components, complex pipeline arrangement, high demand for component types and quantities lead to technical problems that increase the cost of the whole machine, and propose a heat dissipation structure of the air conditioner electric control box and air conditioner with a simplified structure and low cost.
