摘要
Abstract
The phased array antenna of missile-borne radar needs to work long hours in experimental tests and maintenance, and provide short-time reliable work performance without any cooling measure on the missile. According to the requirement,a structure design method for antenna front-end is presented,with which cooling elements can be replaced quickly based on wedge locking device. The method utilizes liquid cooling and thermal storage based on paraffin/graphite composite phase-change material ( PCM ) as the means of cooling to achieve steady-state cooling and transient thermal control respectively. The mathemati-cal models and simulation methods during the calculation of thermal storage based on PCM are described. Simulations and experiments show that the proposed front-end design of phased array antenna meets the re-quirements for stable work in thermal environments of both steady state and transient state( multiple work-ing conditions) . The heat sink effect of thermal storage based on paraffin/graphite PCM is superior to that of the tradition.关键词
