HEAT ACOUSTIC DEVICE AND HEAT ACOUSTIC SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a heat acoustic device capable of rapidly and efficiently performing heat exchange by rapidly generating standing waves and traveling waves in the heat acoustic device using a loop tube.

SOLUTION: A first stack 3a held by a first high temperature side heat exchanger 4 and a first low temperature side heat exchanger 5 and a second stack 3b held by a second high temperature side heat exchanger 6 and a second low temperature side heat exchanger 7 are installed in the loop tube 2. Sound waves by excitation are generated by heating the first high temperature side heat exchanger 4, and the second low temperature side heat exchanger 7 is cooled by the standing waves and the traveling waves thereof. The loop tube comprises a plurality of straight tube parts 2a along a vertical direction and a connecting tube part 2b formed shorter than the straight tube parts 2a. The first stack 3a is installed in the longest straight tube part 2a.
