COMPACT THERMOELASTIC COOLING SYSTEM
First Claim
1. A cooling system, comprising:
- a pair of rollers driven by a motor, the pair of rollers facing each other with a prescribed gap therebetween;
a looped solid refrigerant belt that is sandwiched by the pair of rollers at the prescribed gap in such a stressed and compressed state that a portion of the solid refrigerant belt that comes out from the gap between the rollers transits to a colder thermodynamic state; and
a cold reservoir containing a cooling medium, continuously receiving the portion of the solid refrigerant belt that comes out from the gap between the rollers so as to cool the cooling medium by said portion of the solid refrigerant belt,wherein the pair of rollers also receive heat from the solid refrigerant belt when the solid refrigerant belt is at the gap so as to act as a heat sink that is directly contacting the solid refrigerant belt, andwherein the solid refrigerant belt is made of a material capable of exhibiting thermoelastic effect.

Abstract
A compact cooling system based on thermoelastic effect is provided. In one embodiment, the system comprises a pair of rollers serving as a heat sink, stress applicator and belt drive, a cold reservoir and a solid refrigerant belt coupled to the cold reservoir and to the heat sinks to pump heat from the cold reservoir to the heat sink. The refrigerant belt comprises solid thermoelastic materials capable of thermoelastic effect. The refrigerant material is mechanically compressed when entering the gap of the roller and subsequently released after passing through. When compressed the refrigerant material transforms to martensite phase and releases heat to the roller and neighboring materials. After released by the rollers, the refrigerant material transforms back to austenite and absorbs heat from the ambient atmosphere.
