Problems solved by technology

However, since the outdoor unit is placed outside, there is a risk of rainwater entering the blower chamber and reaching the reactor
As a result, if the reactor contains moisture, it may cause a short circuit, so a reactor with high heat resistance must be used, which will increase the cost

Abstract

The object of the present invention is to provide an air conditioner, which can improve the cooling effect of the heat-generating parts while preventing water from contacting the heat-generating parts. The outdoor unit (2) of this air conditioner (100) is divided into a blower room (S1) equipped with a blower (27) and a mechanical room (S2) other than the blower room (S1), and a heat generating part (52) is provided. , and have a casing (60) and a water shield (91). The casing (60) is arranged in the blower chamber (S1), has an opening (71b), and accommodates a heat-generating component (52) inside. The water shielding plate (91) is arranged between the position where the opening (71b) is provided on the casing (60) and the position where the heating element (52) is accommodated, and adopts a structure that is easy to breathe and difficult to pass water.

Description

technical field [0001] The present invention relates to an outdoor unit of an air conditioner, and more particularly, to an outdoor unit of an air conditioner which is divided into a blower room provided with a blower and a machine room other than the blower room and provided with heat-generating parts. Background technique [0002] In the outdoor unit of the air conditioner, the inside of the casing of the outdoor unit is usually divided into a blower room and a machine room by a partition plate extending in the vertical direction and the front-rear direction when viewed from the front. A heat exchanger, a blower fan, and the like are installed in the air blower room, and a compressor, a reactor, and the like are installed in the machine room. In addition, in the machine room, there is an electrical component unit that houses various electrical components such as power transistors and capacitors. Using the control circuit in this electrical component unit, it is possible t...
