Abstract: An outdoor unit of an air conditioner includes a compressor that compresses a first refrigerant introduced from an indoor unit of the air conditioner and a condenser that condenses the first refrigerant compressed by the compressor. A first driving circuit drives the compressor and a second driving circuit regulates a voltage of the first driving circuit. A cooling unit includes: a heat dissipation member that comes into thermal contact with the first driving circuit and the second driving circuit, and a refrigerant pipe that is provided in the heat dissipation member, and has a path along which a second refrigerant moves through the first driving circuit and the second driving circuit. As a result, it is possible to efficiently cool the first driving circuit and the second driving circuit.

Abstract: An outdoor unit of an air conditioner includes a housing including an outlet, a fan disposed inside the housing, and a guide guiding air flowing by the fan, wherein the guide includes an inflow portion provided to guide air introduced into the housing to the fan and a diffuser extending from the inflow portion to guide air passing through the fan to the outlet. The inflow portion includes a duct connected to the diffuser, a bell mouth disposed on an upstream side further than the duct and configured such that a width of an inlet end of the bell mouth is wider than a width of an outlet end of the bell mouth, and a guide vane formed on the bell mouth and configured to guide air introduced into the fan.
