ABSTRACT:
A cooling device for an enclosure, specifically parked automotive vehicles, mountable in a window comprising an air channel for introducing normally cool ambient air from outside the vehicle into the vehicle passenger compartment. The atmospheric air channel is positioned so as to cause the ambient air to be forced to the bottom of the vehicle compartment. This introduction of new atmospheric air increases the internal pressure of the vehicle compartment causing the interior air to seek escape by the easiest means possible, such as, the open portion of the window surrounding the inlet of the device. Additionally during days of cooler ambient temperatures the device has a heating member (52) such that it can perform area heating. Further a coanda nozzle (16) is attached to the outlet (14) of the air channel which acts to speed the velocity of the air being forced to the bottom of the vehicle. This increase in air velocity is then utilized to impart some of its energy to the still air at the outside exit of the nozzle thereby increasing the overall exhaust air flow.
