PURPOSE:To provide an automobile air-conditioning device which is thin and which has a high durability against vibration and variation in temperature, by bulging a casing so that the middle part thereof is higher than both end parts thereof, and by inclining the upper end part of an evaporator toward a cylindrical impeller while bulging the casting along the inner surface of the casing. CONSTITUTION:Upper and lower casings 1, 6 having opposite side surfaces one of which is formed therein with a suction port 12 and the other one of which is formed therein with a blow-off port 13 are stored therein with an evaporator 8 and a cylindrical impeller 2a. The cylindrical impeller 2a is disposed downstream of the evaporator 8, and the direction of rotation of the impeller 2a is set so as to be downward as view from the blow-out port 13. Further, the upper and lower casings 1, 6 are bulged so that the middle part thereof is higher than that of the lines connecting between both ends thereof. Further, the upper end part of the evaporator 8 is inclined toward the cylindrical impeller 2a, and the evaporator 8 is bulged along the inner surfaces of the casings. With this arrangement, the evaporator 8 serves as a frame for the upper and lower casings 1, 6 in order to enhance the rigidity of the casing in its entirety, and to make the thickness of the device thin. |
