| 摘要 |
The invention is a thermoacoustic engine-generator (1) and heat pump that converts a thermal gradient into electrical energy. Typically encased in a thermoplastic or metal package, it can range in the size from a microchip, upward. The significant embodiment is in the designing of solid-state heat exchangers (2,8) to make them resonate thermally at a desired frequency, thereby improving the specific power of the engine. The invention uses the superior energy density and thermal conductivity of solids.
