Title:
THERMOACOUSTIC PUMP
Document Type and Number:
WIPO Patent Application WO/2013/151089
Kind Code:
A1
Abstract:
In order to obtain a required pressure without using a movable part such as a piston, and with high durability and without increasing the heat source temperature when a thermoacoustic engine is used, this thermoacoustic pump (10) is equipped with: multiple thermoacoustic engines (11) wherein a heating unit (21), a stack (22) and a cooling unit (23) are provided on a resonance tube (20) filled with an operating fluid; a connecting pipe (12) connecting the resonance tubes (20) of the multiple thermoacoustic engines (11) in multiple stages; a suction pipe (13) connected to the resonance tube (20) of the thermoacoustic engine (11) located at the uppermost stage; a suction-use check valve (14) attached to the suction pipe (13); a connection-use check valve (15) attached to the connecting pipe (12); a discharge pipe (16) connected to the resonance tube (20) of the thermoacoustic engine (11) located at the lowermost stage; and a discharge-use check valve (17) attached to the discharge pipe (16). The resonant frequency of the sound waves generated in the resonance tube (20) of the thermoacoustic engine (11) located at a lower stage is set so as to be lower than the resonant frequency of the sound waves generated in the resonance tube (20) of the thermoacoustic engine (11) located at an upper stage.
