Title:
MAGNETIC REFRIGERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/199139
Kind Code:
A1
Abstract:
Provided is a magnetic refrigerating device with improved refrigerating capacity and refrigerating efficiency by way of improving the heat exchanging method between a magnetic body and a heat exchanging fluid and devising a magnetic field applying method. The magnetic refrigerating device comprises: a cylindrical active magnetic regenerator (AMR) container that accommodates a refrigerant therein; two magnetic bodies that are disposed in the AMR container in the axial direction, that are configured to be movable in the axial direction of the AMR container, and that are made of material having a magnetocaloric effect; at least two permanent magnets positioned to face the two magnetic bodies in the AMR container; a rotary shaft that is positioned between the two magnetic bodies in the AMR container and that is positioned between the at least two permanent magnets; and a magnetic rotary movement unit that rotationally moves the permanent magnets about the rotary shaft and that repeatedly moves the permanent magnets and the two magnetic bodies closer together and farther apart in association with the rotational movement.
