ABSTRACT:
A compressor-expander type cooling, or heating system, is incorporated into a heel of a shoe, and is powered by reciprocal gravity pressures upon the shoe which occur naturally during walking. The cooling system functions through a bellows compressor chamber and a separate bellows expander chamber. The movable walls of the expander and the compressor are placed opposite each other, and transmit opposing vector forces to each other. A movable heel portion at the bottom of the shoe transmits movement to the movable walls of the compressor and the expander whenever the person wearing the shoes steps on the heel. This expands the expander and compresses the compressor. A network of heat exchange coils, containing a low boiling point liquid, communicates with the expander, and functions as heat absorbing evaporator. Another network of heat exchange coils communicates with the compressor chamber, and functions as a heat delivering condenser. Depending on the locations the evaporator and the condenser networks, the shoe can serve as a foot cooler or a foot warmer.
