ABSTRACT:
A heat transfer system, e.g., refrigeration system or heater, particularly aluable at cryogenic temperatures which comprises a serial arrangement, in abutting contact and connected to the material or device to be cooled or heated, of a thermal reservoir made of a material having a specific heat capacity, a thermal valve made of a thermally-conductive material whose thermal conductivity increases as its temperature increases, e.g., magnesium, a working material whose temperature is periodically varied, e.g., by magnetic or electric fields, and another valve of a thermal-conductive material whose thermal conductivity decreases as its temperature increases, e.g., NaCl. The magnetic refrigeration or heater units may be ganged to increase the cooling or heating ability.
