Author(s) : PRENGER F. E.

Type of article: Article

Summary

INITIAL PERFORMANCE TEST RESULTS OF A PROTOTYPE OF A CONDUCTIVE MAGNETIC REFRIGERATOR REJECTING HEAT TO A 4.5 K SINK ARE PRESENTED. THE PROTOTYPE USES GADOLINIUM GALLIUM GARNET AS THE WORKING MATERIAL, OPERATES IN A CARNOT CYCLE, USES NIOBIUM-TITANIUM MAGNETS AND EMPLOYS CONDUCTION HEAT TRANSFER INTERNALLY. THE DATA PRESENTED ARE USED TO VALIDATE AN ANALYTICAL MODEL OF THE DEVICE. PERFORMANCE LIMITATIONS FROM CIRCUMFERENTIAL CONDUCTION AND INTERNAL FRICTION ARE IDENTIFIED AND DISCUSSED.
