COOLING SYSTEM UTILIZING A RECIPROCATING PISTON

摘要

Cooling in the supersonic region of a compressible fluid is disclosed. The fluid is accelerated by a reciprocating piston to a velocity equal to or greater than the speed of sound in the fluid in an evaporator. No conventional mechanical pump is required to accelerate the fluid. A phase change of the fluid due to a pressure differential may be utilized to transfer heat from an element to be cooled.
