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.

Outdoor unit of air conditioner

An air conditioner includes a heat exchanger including a refrigerant tube, a fin assembly, and a fan assembly located at an upper portion of the heat exchanger. The heat exchanger includes a first heat exchanger adjacent to the fan assembly and a second heat exchanger under the first heat exchanger. A density of a fin assembly at the first heat exchanger is larger than that of a fin assembly at the second heat exchanger. The heat exchanger may include a plurality of layers with a refrigerant introduced into each of inlet pipes of the heat exchanger flowing evenly at each of the layers. The refrigerant to be discharged to each of outlet pipes is discharged at the same temperature.
