Summary

A sound wave cooling system utilizes the local expansion and compression of gas (helium, air, etc.) and the heat transfer between gas and the solid wall of the sound channel. Since the principle of the heat pumping effect involves intrinsically irreversible phenomena, the efficiency of the energy conversion is relatively low. But the main feature of these kinds of devices is the simplicity of the structure and high reliability. An easy explanation of the principle of "heat pumping by sound" is presented and some experimental results gained by authors' group are also shown. This kind of technology is expected to be developed for practical use, in light of the CFC phase-out.
