Abstract:
1. A magnetic refrigerator comprising: a generating unit which generates a magnetic field increased and reduced alternately; a magnetic block including positive and negative magnetic segments which are alternately arranged with gaps and to which the magnetic field is applied, the positive magnetic segments producing heat depending on the increasing of the magnetic field and absorbing heat depending on the decreasing of the magnetic field, and the negative magnetic segments producing heat depending on the decreasing of the magnetic field and absorbing heat depending on the increasing of the magnetic field; and a heat conducting unit configured to conduct heat between the positive and negative magnetic segments, which includes a conducting member which is inserted into the gap and removed from the gap, alternately, in accordance with the increasing or decreasing of the magnetic field, the positive and negative magnetic segments and the conducting member forming a heat conducting path in the magnetic block.
