Patent ID: 6877550

Claim:
An air conditioner for a vehicle, comprising: a blower for blowing air; a cooling heat exchanger for cooling air blown by the blower, the cooling heat exchanger being disposed entirely above the blower in such a manner that air blown from the blower is directly introduced to the cooling heat exchanger and passes through the cooling heat exchanger upwardly from below, wherein: the cooling heat exchanger has a bottom heat-exchanging surface and is tilted downwardly in a tilt direction (t 1 ) by a predetermined angle (θ) relative to a horizontal surface; the blower has a centrifugal fan for blowing air, and a scroll casing for accommodating the centrifugal fan; the scroll casing is disposed such that a dimension γ from a center of the centrifugal fan to a radial peripheral surface of the scroll casing is gradually increased from a scroll start portion to a scroll finish portion, and air is mainly blown toward the cooling heat exchanger in a direction substantially parallel to a tangential line (T) at the scroll finish portion; and the blower is disposed such that an extension line of the tangential line (T) intersects the bottom heat-exchanging surface to form an acute angle with respect to the tilt direction.
