Magnetic heat exchanging unit for magnetic refrigerator

Abstract

A magnetic refrigerator includes a magnetic heat exchange unit including a magnet.

1 . A magnetic heat exchange unit, comprising:
 a container including an inlet port, an outlet port and a magnetic heat exchange chamber;   a magnetocaloric material contained in the magnetic heat exchange chamber, the magnetocaloric material exchanging heat by allowing a flow of a heat transfer fluid to pass through; and   a magnet for applying an attractive force to the magnetocaloric material.   
   
   
       2 . The magnetic heat exchange unit in accordance with  claim 1 , wherein the magnet is attached to the container. 
   
   
       3 . The magnetic heat exchange unit in accordance with  claim 1 , wherein the magnet is disposed in the magnetocaloric material. 
   
   
       4 . The magnetic heat exchange unit in accordance with  claim 1 , further comprising a mesh disposed at the inlet port and the outlet port, respectively. 
   
   
       5 . The magnetic heat exchange unit in accordance with  claim 4 , wherein the magnetocaloric material comprises gadolinium.
