A144 Enhancement of apparent thermal conductivity or magnetocaloric material for magnetic refrigeration

Abstract

A magnetic refrigerator system without a refrigerant in which heat is transported from the cold to the hot side through well-controlled thermal switches is proposed. For the purpose of fast heat transfer between neighboring magnetocaloric material slabs, the effect of configuration of magnetocaloric material slab comprised of high thermal conductivity material and magnetocaloric material on apparent thermal conductivity is evaluated under ideal condition by numerical simulation. It is clarified that the configuration affects the apparent thermal conductivity. The specifications to enhance thermal conductivity are also shown.
