一种复合型核电池的理论设计
首发时间:2009-04-16
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。

Theoretical Design of A Direct-Collection Integrating Thermoelectricity Nuclear Cell
Abstract:In all types of nuclear battery,the structure of direct-collection nuclear cell(DCC) is simplest,but DCC has low efficiency.Partly because many charged particles emitted by radioisotope reversely emit into emitter electrode converting waste heat.Considering how to make use of the waste heat,a composite nuclear battery is designed,which integrates thermoelectric conversion device based on the structure of DCC.In this case,the waste heat generated in DCC can be utilized, and the creative structure of composite nuclear battery can increase 1% efficiency of DCC.
Keywords: nuclear battery thermoelectric conversion waste heat utilizing composite nuclear battery
