Electric control heat dissipation structure, air conditioner outdoor unit and air conditioner

Abstract

The invention discloses an electric control heat dissipation structure, an air conditioner outdoor unit and an air conditioner. The electric control heat dissipation structure comprises a heat dissipation piece, a refrigerant pipe and a cover plate, wherein the heat dissipation piece is provided with a mounting side and a heat conduction side which are opposite, and a leading-in end and a leading-out end which are located between the mounting side and the heat conduction side and are oppositely arranged; the mounting side is provided with a mounting groove; the mounting groove penetrates through the leading-in end and / or the leading-out end; a first containing groove is formed in the bottom wall of the mounting groove; the heat conduction side is used for being in heat conduction connection with an electric control element; the cover plate is arranged in the mounting groove and provided with a second containing groove; a mounting hole is defined by the second containing groove and the first containing groove jointly; and the refrigerant pipe is arranged in the mounting hole and used for conducting heat exchange with the heat dissipation piece. The heat of the electric control element is transmitted to the mounting hole through the heat conduction side of the heat dissipation piece, so that the refrigerant pipe exchanges heat with the heat dissipation piece so as to take away the heat of the heat dissipation piece, and meanwhile, the refrigerant pipe is kept in contact with the heat dissipation piece through the cover plate so as to prevent the refrigerant pipe from being separated from the heat dissipation piece.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an electronically controlled heat dissipation structure, an air conditioner outdoor unit and an air conditioner. Background technique [0002] There are multiple electronic components on the electric control board of the outdoor unit of the air conditioner, including many heat-generating components with large heat generation, such as frequency conversion modules, etc. If these heating components cannot be cooled, it will cause the heating components themselves and even surrounding electronic components to The failure rate is greatly increased. At present, there are two commonly used heat dissipation technologies: natural heat dissipation and refrigerant heat dissipation. Among them, the disadvantage of natural heat dissipation is that the effect is poor, and the temperature rise of the heating device causes the device to be easily damaged and the life is short; while the ...
