To dispense with a moving component such as a piston, achieve high durability, and obtain a necessary pressure without increasing a heat source temperature during use of a thermoacoustic engine.
A thermoacoustic pump 10 includes: a plurality of thermoacoustic engines 11, in each of which a heating part 21, a stack 22 and a cooling part 23 are disposed in a pipe part 20 filled with a working fluid; a connection pipe 12 connecting the pipe parts 20 of a plurality of thermoacoustic engines 11 in multiple stages; a suction pipe 13 connected to the pipe part 20 of the thermoacoustic engine 11 positioned in the uppermost stage; a check valve 14 for suction attached to the suction pipe 13; a check valve 15 for connection attached to the connection pipe 12; a discharge pipe 16 connected to the pipe part 20 of the thermoacoustic engine 11 positioned in the lowermost stage; and a check valve 17 for discharge attached to the discharge pipe 16. The stacks 22 are set so that the thermal relaxation time of the working fluid in the stack 22 of the thermoacoustic engine 11 positioned in the lower stage is shorter than that of the working fluid in the stack 22 of the thermoacoustic engine 11 positioned in the upper stage.
