Abstract:The running conditions of the space-borne Stirling convertor is rigorous,such as high temperature and
pressure from inner working fluid. To ensure long longevity and high efficiency heat transfer of the heater head, the
materials,structure and so on are need to be analyzed and optimized. In this paper, the structure design principle,analysis,
demands for the heater head of space-borne Stirling convertor are introduced. The difficulty of the heater head
structure is also analyzed in this paper. The heater head optimistic design combined with stress analysis produced by
both temperature and pressure were carried out with the aid of commercial finite element method,the finial heater head
structure design was completed and fabricated,the hardware was integrated on the Stirling engine,the heater head performance
is satisfied with the experiment demands.
