Abstract
A heat exchanger bed is formed from a cascade of at least three different magnetocaloric materials with different Curie temperatures, which are arranged in succession by ascending or descending Curie temperature and are preferably isolated from one another by intermediate thermal and/or electrical insulators, the difference in the Curie temperatures of adjacent magnetocaloric materials being 0.5 to 6° C.
Claims15
A heat exchanger bed comprising a cascade comprising at least three different magnetocaloric materials having different Curie temperatures, which are arranged in succession by ascending or descending Curie temperature and are optionally insulated from one another by intermediate thermal and/or electrical insulators,
- wherein the difference in the Curie temperatures of adjacent magnetocaloric materials is from 0.5 to 2.5° C.
