Abstract

A cooling unit for automobile air conditioners includes a pair of scroll-shaped blower cases each composed of an upper case member integrally formed with the upper case member of a cooling case, a lower neck portion integrally formed with the lower case member of the cooling case, and a removable lower case portion detachably disposed between the upper case member and the lower neck portion. The cooling unit also includes a bracket composed of a bracket body integrally formed with the upper case member of the cooling case, and a retaining member detachably connected to the bracket body for holding a blower motor from the below. With this construction, a blower can readily be removed downwardly from the cooling unit by detaching the removable portion and the retaining member even though the cooling unit is mounted on the ceiling of a vehicle.
