PURPOSE:To promote the cooling effect of a base plate and to downsize the construction of the air conditioner by constituting the base plate as a part of a wall surface of a vent passage or a part of a casing constituting a blower. CONSTITUTION:Since a base plate 17 disposed with electronic parts such as a transistor or the like having a large capacitance for driving a motor 13 or the like is constituted as a part of a wall surface 20 of a vent passage 16 and the base plate 17 is faced with the inner part of the vent passage 16, electronic parts and the like are forcibly cooled by an airstream blowing within the vent passage 16. Further, since electronic parts and the like on the base plate 17 are hermetically sealed by an insulating member 18, any protection for the water content and the like within the airstream is carried out sufficiently. On the other hand, the heat radiating effect of the base plate 17 can be improved by heat radiating fins 19 disposed on the front surface of the base plate 17 and projected within the vent passage 16 and at the same time, a smoothing effect for the airstream due to the heat radiating fins 19 can be obtained. |
