Abstract

The invention discloses an electric control component, an outdoor unit and an air conditioner. The electric control component includes a main controller, a rectifier bridge, a PFC circuit, a DC bus capacitor and a compressor IPM module, and the rectifier bridge, the PFC circuit and the compressor IPM module in sequence connection, the DC bus capacitor is connected in parallel to the output end of the PFC circuit, the main controller is connected to the PFC circuit and the IPM module of the compressor respectively; Tank contact heat dissipation; the first circuit board, rectifier bridge, compressor IPM module, PFC circuit and DC bus capacitor are all set on the first circuit board, and the first circuit board is set in the box body; the second circuit board, the main controller is set on the second circuit board. The invention utilizes the low-temperature working environment of the liquid storage tank to improve the heat dissipation rate of the electric control component.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to an electric control component, an outdoor unit and an air conditioner. Background technique [0002] In air conditioners, refrigerators and other electrical equipment equipped with frequency converters, PFC, IPM and other circuits are generally installed, and these circuit components will generate heat during work. If they are not dissipated in time, it is likely to affect the electrical equipment. work performance. For this reason, it is necessary to cool down the heating elements such as PFC and IPM to ensure their reliability and service life. [0003] At present, most of the above-mentioned heating elements adopt the method of connecting an external metal radiator. For example, in an air conditioner, it is also possible to dissipate heat through an outdoor unit fan. This method needs to increase the power of the fan and increase the volume of the radiator,...

Problems solved by technology

[0003] At present, most of the above-mentioned heating elements adopt the method of connecting an external metal radiator. For example, in an air conditioner, it is also possible to dissipate heat through an outdoor unit fan. This method needs to increase the power of the fan and increase the volume of the radiator, resulting in The heat dissipation cost has increased, but the heat dissipation efficiency is still low, and the temperature of heating elements such as PFC and IPM is still above 100 degrees
