Title:
MAGNETO-CALORIC ELEMENT AND MAGNETIC HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163365
Kind Code:
A1
Abstract:
[Problem] To provide: a magneto-caloric element with which heat exchange efficiency, such as refrigeration capacity, can be further improved by a simple design; and a magnetic heat pump device using the same. [Solution] This magneto-caloric element 20 for magnetic heat pumps has a plurality of magnetic bodies having different Curie temperatures and arranged sequentially along an axial direction, in the order of the Curie temperatures thereof. If the magnetic body having a lower Curie temperature among adjacent magnetic bodies is referred to as a low-side magnetic body and the magnetic body having a higher Curie temperature among the adjacent magnetic bodies is referred to as a high-side magnetic body, the intersection point P between the entropy variation curve of the material constituting the low-side magnetic body and the entropy variation curve of the material constituting the high-side magnetic body is located at a position at which the entropy variation value is higher than the half-value width 9 of the entropy variation distribution of the material constituting the low-side magnetic body.
