Abstract:
An air conditioner case comprising:a blower case unit provided with a distended portion formed in a roughly cylindrical shape, an air intake port for taking in air at one side thereof and a blower mounting hole for inserting a blower at another side thereof;a temperature controller case unit located at the downstream side of said blower case unit, in which at least a heat exchanger is housed; anda scroll nose portion located at the boundary of said blower case unit and said temperature controller case unit, which is provided with a cooling air intake chamber, wherein:said blower case unit and said temperature controller case unit are formed by bonding a first case member and a second case member;said first case member includes a semi-circular edge portion for forming said air intake port and a semi-circular edge portion for forming said blower mounting hole and is provided with said cooling air intake chamber;said second case member includes a semi-circular edge portion for forming said air intake port and a semi-circular edge portion for forming said blower mounting hole;said cooling air intake chamber is defined by a partitioning wall standing erect and perpendicular to openings of said blower mounting hole and said air intake port from said scroll nose portion, a barrier wall extending out from a lower edge side of said partitioning wall to constitute a bottom surface thereof and three barrier walls that stand erect and perpendicular to three edge sides of said barrier wall to constitute side surfaces;an opening portion is formed taking up an approximately equal area to the area of a cross section of said cooling air intake chamber at a side opposite from said barrier wall that constitutes said bottom surface of said cooling air intake chamber, and opens in a direction perpendicular to said blower mounting hole;an air inflow port is formed at one of said three barrier walls constituting said side surfaces of said cooling air intake chamber that is located closest to said temperature controller case unit; andan air outflow port is formed at one of said three barrier walls constituting said side surfaces of said cooling air intake chamber that is located at a side where said blower mounting hole is provided.
