Title:
回転磁石式磁気冷凍機
Document Type and Number:
Japanese Patent JP4908469
Kind Code:
B2
Abstract:
A magnetic refrigeration apparatus has an annular container including a plurality of magnetic regenerator compartments containing magnetocaloric material, and a magnet mounted for rotation around the annular container, whereby the motion of the magnet produces a variation of magnetic field strength in the magnetic regenerator compartments, which in term leads to a variation in temperature of the magnetocaloric material in the magnetic regenerator compartments. Heat transfer fluid is propelled by a pump, and directed to and from the regenerator compartments and hot and cold heat exchangers by valves. Each valve includes an axial port and a plurality of radial ports.
