Abstract Directed energy weapons work for intermittent warfare, it produces more than million watt heat during the few seconds of emission, which would result in bringing a great lot of thermal load and high heat flux on the surface。 Currently, spray cooling is a promising cooling method to the relatively high heat flux in the field of electronics。 However, although the relevant institutions abroad have done a certain degree of research on the spray cooling system, there is a little research of thermal system on directed energy weapons, especially to the question of liquid cooling spray system terminal。 In this paper, we aim at addressing the needs of demand heat load of high energy weapons。 We have done some work such as the selection of efficient heat storage material , design of heat storage structure, the proposed strengthened method of heat storage or dissipated, and the creation of thermal storage scheme simulation model。 At the same time, based on the above thermal storage system studies, it has been done to the design and research of 600kW thermal energy weapon system 。And it is formed to meet the thermal
management of high energy weapon system integration solutions。 This research results provide technical support of high energy weapons cooling system。
