Electric controller based on heat-superconducting cooling plate, and outdoor unit of air conditioner

Abstract

The invention provides an electric controller based on a heat-superconducting cooling plate, and an outdoor unit of an air conditioner. The electric controller based on the heat-superconducting cooling plate comprises an electric controller body and the heat-superconducting cooling plate. The electric controller body comprises a printed circuit board (PCB) and electronic components. The electronic components include a power device high in heating capacity and the electronic components small in heating capacity. The power device high in heating capacity is located on a first surface of the PCB, and the electronic components small in heating capacity are located on a second surface of the PCB. The heat-superconducting cooling plate is attached to the surface of the power device high in heating capacity. The power device high in heating capacity is arranged on the first surface of the PCB, and the electronic components small in heating capacity are arranged on the other surface of the PCB, so that installation of the heat-superconducting cooling plate and the power device high in heating capacity and protection of the other electronic components are facilitated, and the reliability of the outdoor unit of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an electric controller and an air-conditioning outdoor unit based on a thermal superconducting cooling plate. Background technique [0002] With the development of technology, people have higher and higher requirements for the quality of life. Air conditioners with high efficiency, quietness, frequency conversion, energy saving and intelligent control have become indispensable equipment in people's daily life. As the functions of air-conditioning electric controllers become more and more powerful, the heat generated by power modules such as IGBT, MOSFET, Diode, and IPM in the electric controllers is increasing, and the requirements for heat dissipation are also getting higher and higher, making air-conditioning manufacturers more and more demanding. More and more attention has been paid to the thermal design of air conditioner electric controllers. [0003] Fo...
