<P>PROBLEM TO BE SOLVED: To provide a thermoacoustic engine capable of effectively recovering heat inputted from a heat source. <P>SOLUTION: The thermoacoustic engine 10 makes an oscillator 12 oscillate and heats cooling water into hot water with heat, by inputting heat to a first hot-side heat exchanger 32 and by inputting cooling water to a first cold-side heat exchanger 33. Then, the heated hot water is inputted to a second hot-side heat exchanger 36, and a second cold-side heat exchanger 37 is cooled. In this condition, a vibration of the oscillator 12 oscillating propagates to a heat storage unit 14, and the hot water inputted to the second hot-side heat exchanger 36 is heated thereby. The thermoacoustic engine 10 includes a cooling water passage 15 guiding cooling water to the first cold-side heat exchanger 33, and further includes a flow controller 16 for controlling a flow rate of the cooling water in the cooling water passage 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
