Abstract

Abstract: The heat transfer process of SZ-spaceship′s radiator was analyzed and optimized for the finwidth of fintube single phase flood-loop radiator,the popular evaluation method of space radiatorsheat rejectionweight（HR/W）ratio equation.Through analytic and numerical method,HR/W ratio equation was introduced and solved and the best fin-width expression for max and microheat rejectionweight ratio were obtained.In the end,The parameters of SZ-spaceship radiator vsthe optimized radiator was compared.It shows that the proposed method provides useful references for radiator optimization design.

Key words: Fin-tube radiator, Fluid-loop, Heat rejection-weight ratio, Optimizing analytic, Spacecraft
