Title:
MAGNETOCALORIFIC MATERIAL BED AND MAGNETIC REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/052960
Kind Code:
A1
Abstract:
The present invention obtains a magnetocalorific material bed in which a heat-storing member is provided to a flow path within which a plurality of types of magnetocalorific materials are provided so that the Curie temperatures thereof sequentially increase from one end toward the other end, thereby making it possible to cause the magnetocalorific materials to swiftly reach the respective Curie temperatures when a device is started up, and making it possible to improve the operation efficiency. This magnetocalorific material bed (10) comprises: a flow path (20) through which a heat exchange fluid (9) flows in a circulatory manner between one end and the other end; a plurality of types of magnetocalorific materials (21) that are provided within the flow path (20) such that the Curie temperatures of the magnetocalorific materials (21) sequentially increase from the one end to the other end, the magnetocalorific materials (21) undergoing heat exchange with the heat exchange fluid (9); and a plurality of types of heat-storing members (22) that are provided to the flow path (20) so that the phase transition temperatures of the heat-storing members (22) sequentially increase from the one end to the other end.
