Abstract

The aim of the invention is to provide an miniaturization outdoor machine of air conditioner which protects the electric components from physical load of the exterior. The electric components include: a circuit board back case; a circuit board for the electric components making the circuit board back fixed opposite to the circuit board back case while in the another region of the circuit board is disposed with accumbent frequency converter module etc.; a supporting part fixed on the circuit board back case, namely, a supporting part for supporting and fixing another end side of the circuit board through a way of connecting the circuit board back case and the circuit board using the bridge, supporting a part disposed with frequency converter module; and a circuit board top case for covering the top side of the circuit board. The electric component box is fixed on the clapboard, thereby the gauge of another side for the circuit board top case is smaller than that in the nearer side, and the part with smaller gauge is faced with the blower.

Description

technical field [0001] The present invention relates to an outdoor unit of an air conditioner. Background technique [0002] A general split air conditioner consists of an indoor unit and an outdoor unit. The indoor unit is equipped with the minimum equipment for delivering the predetermined air-conditioned air, and the outdoor unit is equipped with a heat exchanger, a blower, a compressor for delivering refrigerant, and an electrical component box (electrical parts box) for operation control. part housing). [0003] The inverter module installed in the electrical parts box generates a particularly large amount of heat, so it is important to dissipate heat from the module, and it is also important to dissipate heat from other components such as diodes for rectification that convert AC power into DC power. Critical. As a method of heat dissipation, a method of either installing a heat sink or ventilating to improve the heat dissipation effect is widely used. [0004] Exam...
