Description

BACKGROUND OF THE PRESENT INVENTIONField of Invention[0001]The present invention relates to the technical field of air conditioning devices, and in particular, to an electric controller based on a thermally superconducting heat dissipation plate, and an air conditioner outdoor unit.Description of Related Arts[0002]With the development of technology, people have higher requirements on quality of life, high-efficient, silent, variable-frequency, and energy-saving air conditioners with intelligent control have become indispensable in daily life. As function of the electric controller of an air conditioner becomes stronger, power modules such as an insulated gate bipolar transistor (IGBT), a metal-oxide semiconductor field-effect transistor (MOSFET), a diode, and an intelligent power module (IPM) in the electric controller generate more heat, and a heat dissipation requirement becomes higher. Therefore, air conditioner manufacturer pays more attention to thermal designs of electric cont...

AI Technical Summary

Benefits of technology

The present invention is an electric controller and an air conditioner outdoor unit that use a thermally superconducting heat dissipation plate to resolve issues in the prior art, such as complexity, increased refrigerant amount and compressor load, additional leakage points, and reduced system reliability when liquid cooling is used for heat dissipation. The technical effect is the improved efficiency and reliability of the electric controller and air conditioner system.

Problems solved by technology

For a high-performance variable-frequency heat pump air conditioner, the conventional radiator made of extruded aluminum can no longer meet the heat dissipation requirement.

However, refrigerant inlet and outlet pipes need to be disposed in this heat dissipation method, which will make the refrigerant pipeline system of the entire air conditioner complex, and increase the amount of the refrigerant and the load of the compressor.

Moreover, adding refrigerant branch requires joint connections and new pipes, not only costs but also leakage points of the refrigerant system are increased, which will lower the reliability of the system.
