Abstract

The present invention is a cooling device, wherein cooling is effected by enclosing a working fluid in a conduit, which is formed by providing a looped tube formed by interconnecting both respective ends of a stack combining a hot heat exchanger with a cold heat exchanger and a stack combining a cooling heat exchanger with a cooling output heat exchanger and by providing at least one or more acoustic wave generators outside or/and inside the looped tube, and then generating a standing wave and traveling wave in the working fluid, with the present cooling device being primarily capable of markedly shortening the time until the start of generation of the standing wave and traveling wave and providing stable control.
