ABSTRACT:
Improved cooling of electronic heat loads aboard aircraft is achieved in a system including a sealable aircraft cabin (10), first and second electronic heat loads (38), (40) and a means (42) for maintaining a desired pressure within the cabin (10). A rotatable turbine wheel (16) is associated with an overboard dump port (32) such that air being dumped overboard from the cabin is expanded to rotate the turbine wheel (16). A mechanical load (20) is connected to the turbine wheel (16) for harnessing the rotation thereof and means (24), (60) are employed for using the air expanded by the turbine wheel (16) for cooling at least one of the loads (38), (40).
