Abstract
The invention provides a method of making a magnetic regenerator for an active magnetic refrigerator, the method comprising: forming a magnetic regenerator from a slurry or a paste containing a magnetocaloric material the magnetic regenerator being formed to have plural paths therethrough for the flow of a heat transfer fluid; and varying the composition of the magnetocaloric material so that the magnetic transition temperature of the magnetic regenerator varies along the paths.
Claims6
A magnetic regenerator comprising plural paths made of a ceramic material through which in use a heat transfer fluid is made to flow back and forth, wherein the magnetic transition temperature of the magnetic regenerator varies along the paths wherein the channels are between plates of magnetocaloric material, the separation of the plates being between 0.1 mm and 0.5 mm.
