Title:
MAGNETIC REFRIGERATION HEAT PUMP DEVICE
Document Type and Number:
Japanese Patent JP2019117027
Kind Code:
A
Abstract:
To restrict loss in flow of heat conduction medium caused by an increase viscosity of the heat conduction medium at a low temperature taking-out side even if it is constituted to have several kinds of magnetic materials laminated up at a working room.SOLUTION: This invention relates to a magnetic refrigeration heat pump device in which a permanent magnet 3 rotatable around a central shaft and several working chambers 2 arranged at an outer peripheral side of said permanent magnet 3 in a circular form and each of said working chambers 2 has several magnetic materials having different Curie points laminated.along an axial direction. At least one of a sectional area of said working chamber 2 and a density of the magnetic material is adjusted in such a way that a pressure loss at a part storing the magnetic material having a low Curie point becomes lower than a pressure loss at a port storing the magnetic material having a high Curie point along an axial direction when the heat conduction medium is press fed to said working chamber 2 under a state where the permanent magnet 3 is not present.SELECTED DRAWING: Figure 2
