ABSTRACT:
An air cooling system having a rotary assembly within a non-circular chamber wherein compression and expansion used in a modified reverse Brayton cycle are provided within the same chamber by the change in volume brought about by vanes sliding within slots in the rotor. Air is supplied to the compressor portion of the chamber from an air-to-air heat exchanger which receives cooled air from the expander. A transfer passage is provided between the output of the compressor and the inlet of the expander. A liquid cooled heat exchanger is provided adjacent the compressor. A second liquid cooled heat exchanger is provided around the transfer passage. Coolant is supplied to the liquid cooled heat exchangers from a radiator.
