PROBLEM TO BE SOLVED: To more efficiently cool heating electronic components installed along a partition plate within an electronic component unit.SOLUTION: In an outdoor unit including a vent hole 50 that communicates an electronic component unit 7 with a blower chamber FC and that is provided in a partition plate 5 that partitions a casing interior into the blower chamber FC including a heat exchanger and a blower fan and a machine chamber MC including a compressor and the electronic component unit 7, a ventilation duct 9 having an open lower end is provided in the electronic component unit 7 so as to cover the vent hole 50 to heating components (an ACTPM 71 and a reactor 72), air in the electronic component unit 7 is attracted from the lower end of the ventilation duct 9 to cool the heating electronic components and then flow into the blower chamber FC from the vent hole 50 in response to a blower fan operation, thereby efficiently cooling the heating electronic components. |
