Abstract

The invention provides an electrical box and an outdoor unit of an air conditioner. The electrical box includes a main body of the electrical box, a PCB board and a radiator. The PCB board and the radiator are installed in the main body of the electrical box. One end of the device is mounted on the surface of the PCB, and the other end is in contact with the heat sink. There is a preset gap between two adjacent power dissipation devices on the PCB, and between the power consumption device and the electrical box body, and the airflow passes through the preset gap. Provide gaps for heat dissipation. Its air-conditioning outdoor unit contains the above-mentioned electrical box. The electrical box and the air conditioner outdoor unit of the present invention have a simple and reasonable structural design. By setting a preset gap between the power consumption devices in the electrical box body, the air flow is facilitated, the natural convection of the power consumption devices is enhanced, and the work of the power consumption devices is reduced. The surface temperature at the time, thereby improving the reliability of the electrical box.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an electrical box and an air conditioner outdoor unit containing the electrical box. Background technique [0002] The controller is the center of a machine's operation, similar to the brain function of the human body. The electrical box is the main structure to ensure the normal and reliable operation of the motherboard. Whether the electrical box can work reliably will directly affect whether the entire machine works normally. The current electrical box is constantly improving with the progress of technology and technology, and the integration of both key components and circuit systems. critical issue for proper functioning. [0003] The main idea of ​​the existing heat dissipation method is to conduct heat conduction heat dissipation for key power consumption devices (such as IGBTs, diodes, IPMs, etc.). The heat of the device is transferred to the radiator, and...
