Air conditioner, outdoor machine and electric box of outdoor machine

Abstract

The invention discloses an air conditioner, an outdoor machine and an electric box of the outdoor machine. The electric box comprises a box body of which one side is open to form an opening, and a sealing board which is fixedly connected to the opening of the box body, wherein the sealing board can block off the opening, and a plurality of heat dissipation through holes allowing convex components on a PCB (printed circuit board) to penetrate through are formed in the sealing board; patch components on the PCB in the electric box are encapsulated on the inner side of the sealing board. The patch components on the PCB in the electric box are encapsulated on the inner side of the sealing board, and in this way, the patch components on the PCB are no longer directly exposed, so that the situations that the PCB adsorbs a great deal of dust after the PCB is used for a long term and the PCB is liable to corrode by sulfur ingredients from sound-proof cotton are avoided. The components needing heat dissipation in the convex components on the PCB can penetrate through the heat dissipation through holes, so that the normal heat dissipation of high-power components is guaranteed, and the reliability of the components on the PCB is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and more specifically, to an air conditioner, an outdoor unit and an electrical box thereof. Background technique [0002] There is a PCB board inside the electrical box of the outdoor unit of the air conditioner. There are many components on the PCB, such as the main chip, resistors and other chip components. The PCB is also equipped with electrolytic capacitors, choke coils and other components that need heat dissipation. . The electrical box in the prior art includes a box body, and one side of the box body is opened to form an opening to facilitate heat dissipation or external connection of components such as electrolytic capacitors and choke coils. In this way, the sealing of the electrical box is poor, and a large amount of dust will be absorbed on the PCB board after long-term use, and the sound insulation cotton of the compressor contains sulfur components. After a period of use...
