摘要
在各类核电池中,直接接收型核电池的结构最简单,但其效率不高。部分原因在于很多带电粒子反向发射,被发射极自吸收而产生废热。考虑到如何把燃料产生的废热利用起来,设计了一种复合型核电池的结构,即在直接接收型核电池结构的基础上,加上热电转换装置,把直接接收型核电池产生的废热转换为电,进而可以明显地提高整个电池1%左右的效率。
In all types of nuclear battery, the structure of parallel plate direct-collection nuclear cell (DCC) is the simplest. However, this kind of DCC has low energy conversion efficiency, because a considerable part of the charged particles emitted by the radioisotope move reversely into the emitter electrode, producing just waste heat. A novel structure of nuclear battery, which integrates thermoelectric conversion device with the DCC, is designed to make use of the waste heat. In this case, the waste heat generated in DCC can be utilized, and the creative structure of composite nuclear battery can increase about 1% efficiency of DCC.
