ACOUSTIC HEATER AND ACOUSTIC HEATING SYSTEM

WIPO Patent Application WO/2005/093339

A1

An acoustic heater capable of heating an object while utilizing thermoacoustic effects and an acoustic heating system. The acoustic heater comprises, at a first tube part (2a), a first stack (3a) held by a high temperature side heat exchanger (4) and a low temperature input side heat exchanger (5) and, at a second tube part (2b), a second stack (3b) held by a low temperature side heat exchanger (6) and a high temperature output side heat exchanger (7). A standing wave and a traveling wave are generated by self-excitation in the first tube part (2a) by cooling the low temperature input side heat exchanger (5) to a negative temperature of 20 to 60°C. By propagating the standing wave and the traveling wave to the second tube part (2b), a temperature gradient is produced in the second stack (3b), and high calorie heat is outputted, by the temperature gradient, from the high temperature output side heat exchanger (7) installed in the second stack (3b).
