| 摘要 |
<p>The present invention embodies a piezo-pyroelectric energy converter (10) and is directed to a method and apparatus for conversion of thermal energy to electrical energy and electrical energy to refrigeration. The present invention utilizes one or more piezo-pyroelectric materials (12, 62, 72) with thermally conductive metal electrodes (14, 64, 68), which resonate at a high frequency and are in thermal communication with a hot heat sink (16) and a cold heat sink (18) to create a thermal gradient and heat flow along the metal electrodes (14, 64, 68) and the piezo-pyroelectric material (12, 62, 72).</p> |
