MAGNETIC CALORIFIC REFRIGERATOR Russian patent published in 1995 - IPC

FIELD: cryogenic engineering. SUBSTANCE: refrigerator has rotor 10 with a permanent magnets, device 8 for reverse pumping of heat carrier, loop 1 for heat carrier circulation defined by hollow magnetic conductors 13 and 14 with heat receiver and units 2-5 for working fluid which are made of porous material, cross-shaped, and positioned from outside perpendicular to its axis of rotation, and members for heat withdrawing. Hot faces of the units point to the rotor. Cold ends of opposite units are interconnected through magnetic conductors. The heat receiver connects spaces of two adjacent magnetic conductors. EFFECT: enhanced efficiency. 1 dwg
