Sound-Fueled Electrical and Cooling System

Thermoacoustic heat exchangers use sound waves to cool heat energy and can provide an efficient way to provide refrigeration in loud environments. In the global transition to cleaner energy, thermoacoustics can supplement existing refrigeration and fueling units for aircraft, ships, engine rooms, server farms, and off-grid power stations.

The U.S. Coast Guard (USCG) saw an opportunity to better harness thermoacoustic technology with a precise, 3D-printed, low-heat conducting stack that allows for sound waves to compress gases and create a cooling system with low-cost additive manufacturing.
