Abstract

PURPOSE: To obtain a magnetic refrigeration cycle in which refrigeration efficiency is enhanced while suppressing vibration and noise by arranging heat pipes between a magnetic body and a high temperature part and between the magnetic body and a low temperature part and then turning a field being applied to the magnetic body on/off electrically. CONSTITUTION: When a strong field is applied to a magnetic body 1 from an electromagnet 2 in a superconducting cooler 27 by turning a switch 25 on, internal magnetic entropy is decreased and the temperature rises instantaneously to a specified level from room temperature. Consequently, the vapor 5 of refrigerant liquid 4 in a heat pipe 3a ascends to heat a heat exchanger 6a but heat is not transmitted to a lower heat exchanger 6b. When the switch 25 is turned off upon elapsing some time, temperature of the magnetic body 1 decreases and the heat exchanger 6a is sustained at high temperature and heat is transmitted from the heat exchanger 6b to the magnetic body 1 through a heat pipe 3b. Consequently, low temperature can be obtained from a lower heat exchanger 7b when upper fins 7a are cooled with room temperature air and a high refrigeration efficiency is attained while suppressing vibration and noise.
