<P>PROBLEM TO BE SOLVED: To provide a thermoacoustic refrigeration device that effectively improves output of a refrigerator. <P>SOLUTION: The thermoacoustic refrigeration device 1 includes: a gas column 2 in which gas is sealed; a motor 3 having a heated-part heat exchanger 5, a regenerator 7, and an ordinary-temperature-part heat exchanger 6 arranged in the gas column 2; a refrigerator 4 having a cooler-part heat exchanger 8, a regenerator 10, and an ordinary-temperature-part heat exchanger 9 arranged in the gas column 2; and a bulkhead 13 arranged in the gas column 2 to prevent circulation flow of the gas sealed in the gas column 2. In a position where the regenerator 10 of the gas column 2 is arranged, a large-diameter part 11 with an inner diameter larger than the gas column 2 is formed. The outer diameter of the regenerator 10 is as large as the inner diameter of the large-diameter part 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
