Description

The thermoacoustic engine that can be driven by cold exergy has been designed and constructed. It is composed of a looped tube, a straight tube, two heat exchangers, a regenerator, and a tank. The regenerator is sandwiched by the heat exchangers and is located in the looped tube. When the temperature ratio of the heat exchangers exceeds 1.7, the gas inside the engine spontaneously oscillates. The amplitude of the oscillation increases with increasing the temperature ratio, and the output power of the engine reaches 190 W.
