Type of article: Article
Summary
A DETAILED CYCLE ANALYSIS OF A MAGNETIC REFRIGERATOR EQUIPPED WITH NEW HEAT SWITCHES WAS PERFORMED, INCLUDING HEAT LOSSES DUE TO HEAT SWITCHES. THE RESULTS SHOW THAT HEAT LOSS RELATED TO INCOMPLETENESS OF HEAT SWITCHES MAINLY RESULTS IN A REDUCTION OF COOLING POWER. THE EXPERIMENTAL HEAT LOSS IS APPROXIMATELY 8 TIMES LARGER THAN THE CALCULATED VALUE. IT IS BELIEVED THAT THIS LARGE HEAT LOSS MAY BE CAUSED BY UNEXPECTED CONVECTION OF LIQUID HELIUM.
