Evaporative cooling system

摘要

An evaporative cooling unit is mounted on the roof of a vehicle wherein a plurality of air blowers are arranged in tendem to deliver cooled air through discharge ducts communicating with the interior of the motor vehicle. The cooling components are mounted in an improved housing of elongated low-profile configuration to extend lengthwise of the vehicle roof and has a base panel conforming to the contour of the roof including ribs defining raised mounting pads projecting upwardly from the base to form interruptions therein. Blowers include ribs with attachments for mounting in spaced relation to the roof, and internal frames in the housing define supports cooperating with the ribs to rigidly mount the blowers in the housing.
