Title:
MAGNETIC HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/088168
Kind Code:
A1
Abstract:
Provided is a magnetic heat pump device (1) comprising: magnetic working bodies (11A-11D); a permanent magnet (6); a circulation pump (24); rotary valves (8, 9); and heat exchangers (21, 28). Ducts (12) in the magnetic working bodies are filled from a low-temperature end (16) to a high-temperature end (14) with a plurality of types of magnetic working substances (13A-13C) in order of how low the Curie points thereof are, the magnetic working substances are thereby connected in cascade, and the dimensions of the areas filled with each of the magnetic working substances are made to correspond to predetermined specific temperature ranges in which there is a large change in temperature in each of the magnetic working substances. Effectively connecting a plurality of types of magnetic working substances in cascade makes it possible to obtain the necessary cooling and heat discharge temperatures.
