HEAT EXCHANGE APPARATUS USING MAGNETIC MATERIALS WITH DIFFERENT CURIE TEMPERATURES

摘要

PURPOSE: A heat exchange device using different kinds of magnetic refrigerating materials is provided to have favorable heat exchange efficiency and the smooth movement of thermal media by heat-exchanging the thermal media and the magnetic refrigerating materials while moving the thermal media from a low-temperature part to a high-temperature part. CONSTITUTION: A heat exchange device using different kinds of magnetic refrigerating materials comprises a magnet(100), a housing(200), a cold end(300), a hot end(350), and a heat exchange member. The magnet generates a magnetic field toward an internal space. The housing is received in the internal space. The cold is coupled to one side of the housing. The hot end is coupled to the other side of the housing. The heat exchanging member is received inside the housing. The magnetic refrigerating materials are deposited on a substrate.
