Abstract
An outdoor unit includes a heat exchanger, a blower fan, an electronic board on which a heat-generating element is mounted, a housing, and a heatsink. The housing includes a partition plate partitioning the inside of the housing into a heat exchanger chamber in which the heat exchanger and the blower fan are placed and a machine chamber in which the electronic board and a compressor are placed, and a portion of the partition plate has an opening. The heatsink includes a main plate placed to cover the opening from the heat-exchanger-room-side of the partition plate and heat-releasing fins projecting from the main plate to the blower fan side, and a portion of the main plate comes into contact with the heat-generating element via the opening. The greater the amounts of heat transferred from the heat-generating element the heat-releasing fins, the larger the heat-releasing fins.
