Abstract

The invention discloses a PCB assembly and an air-conditioner outdoor unit provided therewith. The PCB assembly includes a PCB, a fixing piece assembly and a heating element. The fixing-piece assembly is arranged on the upper surface of the PCB. The fixing-piece assembly is metal parts. The heating element is arranged on the upper surface of the fixing-piece assembly. According to the PCB assembly, through arrangement of the fixing-piece assembly made of a metal and direct arrangement of the heating element on the fixing-piece assembly, part of heat generated during work of the heating element can be transmitted to the PCB through the fixing-piece assembly and dissipated by the PCB. Therefore, the cooling effect of the heating element is improved and reduction of the temperature of the heating element during work is facilitated and damage of the heating element because of overly high temperature is prevented; and through adoption of the fixing-piece assembly made of the metal, the fixing installation strength of the heating element can also be improved significantly.

Description

technical field [0001] The invention relates to the field of air conditioner structures, in particular to a PCB board assembly and an air conditioner outdoor unit having the same. Background technique [0002] The PCB board (Printed Circuit Board, printed circuit board) of the electric control box of the traditional air conditioner outdoor unit can be equipped with multiple heating elements, such as IPM modules, diodes, IGBT modules or rectifier bridges, etc. These heating components are passed through the plastic card The buckle structure is fixed on the PCB board. Since these heating elements will generate a large amount of heat during operation, the temperature of these heating elements will be high during operation, and they will be easily damaged. Moreover, the thermal resistance of the plastic buckle is relatively large, which will affect the heat dissipation to a certain extent. In addition, when the plastic buckle is fixed by wave soldering, the plastic buckle will ...
