Abstract

The invention discloses a split type frequency-variable air conditioner outdoor machine which comprises a casing, a chassis, a compressor, a condenser, a fan motor, an outdoor fan, a baffle plate, a liquid storage tank and a control box. The control box crosses the upper part of the baffle plate, and the interior of the control box is provided with a control circuit board PCB. One side of the lower part of the bottom of the control box is provided with heat radiating fins for radiating the heat generated by the PCB. A suction fan which penetrates through the bottom of the control box is positioned on the side of the heat radiating fins under the bottom of the control box. The exterior of the suction fan is provide with an air guide plate of an air duct for connecting the heat radiating fins and the suction fan, and then the sucked air is blown to the heat radiating fins after cooling the PCB. As the control box of the frequency-variable air condition outdoor machine is additionally provided with the fan and the air passage structure, when the PCB is mounted, the fan works, the cool air decreases the temperature of the PCB through the air duct, and enables the heat to be sufficiently radiated after blowing through the heat radiating fins, therefore the PCB is stable to work, and is favorable for the service life.
