摘　　要：近年来,随着弹载电子设备集成度越来越高,内部热耗不断增加,如何实现设备的高效热管理,成为制约弹载电子设备进一步发展的重大难题。该文提出了一种应用于大功率弹载微波组合的相变储热模块,通过仿真分析手段研究了储热模块主体结构对储热模块整体储热性能的影响。综合考虑可制造性、质量、储热能力等多方面因素后,确认了储热模块的结构形式和最终选用的相变介质材料。利用增材制造技术加工出储热模块样品,并搭建热测试平台完成了该样品的散热效果评估。实验表明,在60℃环境下,模块总热耗为211 W,工作10 min后,模块表面最高温度为104.1℃,满足组合使用要求。该储热设计技术有效地解决了模块短时大功率下温升过高的问题,在弹载电子设备热管理领域有着广阔的应用前景。In recent years,with the increasing integration of missile-borne electronic equipment and the increasing internal heat consumption,how to achieve efficient thermal management of equipment has become a major challenge restricting the further development of missile-borne electronic equipment.In this paper,a phase change heat storage module applied to high-power missile-borne microwave combination is proposed Through simulation analysis,the influence of the main structure of the thermal storage module on the overall heat storage capacity of the heat storage module is studied.After comprehensively considering various factors such as manufacturability,quality,heat storage capacity,the structural form of the heat storage module and the final phase change medium material has been confirmed.A sample of heat storage module was processed by using the additive manufacturing technology,and a thermal test platform was built to evaluate the heat dissipation effect.The experiment shows that the total heat consumption of the module is 211 W at 60 ℃,and the maximum surface temperature of the module is 104.1 ℃ after 10 min of operation,which meets the operating conditions of the microwave combination.The heat storage design technology can effectively solve the problem of high temperature rise under the conditions of short-time and high power of the module,and has broad application prospects in the field of thermal management of missile-borne electronic equipment.
