Electrical box and air conditioner outdoor unit

Abstract

The invention provides an electrical box and an air conditioner outdoor unit. The electrical box comprises a box body, a PCB, and a radiator. The PCB and the radiator are mounted inside the box body. The electrical box further comprises power-consuming devices which generate heat. One end of every power-consuming device is mounted on the surface of the PCB; the other end of every power-consuming device contacts with the radiator. A preset gap is arranged between each two power-consuming devices on the PCB, and another preset gap is arranged between each power-consuming device and the box body; air flow passes the preset gaps to dissipate the heat. The air conditioner outdoor unit comprises the electrical box. The electrical box and the air conditioner outdoor unit have the advantages that the structural design is simple and reasonable, the preset gaps between the power-consuming devices in the box body allow flowing of air, natural convection is enhanced for the power-consuming devices, surface temperature of the power-consuming devices during operation is lowered, and reliability of the electrical box is improved.

Description

Technical field [0001] The present invention relates to the technical field of electrical appliances, in particular to an electrical box and an outdoor unit of an air conditioner containing the electrical box. Background technique [0002] The controller is the center of the operation of a machine, similar to the brain function of the human body. The electrical box is the main structure that guarantees the normal and reliable operation of the motherboard. The reliability of the electrical box will directly affect the normal operation of the entire machine. With the progress of the process and technology, the integration of the current electrical box has been continuously improved. There are not only the integration of key devices, but also the integration of circuit systems. The energy consumption density of the devices is getting higher and higher, and the heat dissipation will affect the ability of electronic devices. The key issue for normal work. [0003] The existing heat dis...
