The heat transfer characteristics of a coupling thermoacoustic sound wave generator is described. When two sound wave generators are combined and operated, the heat transfer characteristics of each of the sound wave generators show results different from those obtained when they are operated independently. The sum of heat transferred by sound wave, Q_<MA>, is the largest for the closed ends connected-type sound wave generator when the stack positions of the two sound wave generators are the same. When frequency, f, is 134Hz, the maximum sum of Q_<MA> is 10% greater than that of two sound wave generators that are independently driven. The stack position where the temperature of hot heat exchanger, T_H, is the lowest does not agree with the optimum stack position in which the sound wave generators are independently operated. It is confirmed that the lowest T_H in the coupling sound wave generator is 50℃ lower than that in the sound wave generators that are independently operated.
