Description
Technical Field
The invention relates to the technical field of thermal control of aerospace devices, in particular to a multi-stage energy storage device.
Background
In recent years, micro-nano electronic technology in the field of thermal control of aerospace devices is rapidly developed, and the integration level of various photoelectric chips and devices is rapidly improved. The improvement of the integration level causes the rapid increase of the heating power of the unit area of the chip, and the problem of thermal barrier is caused by the rapid increase of the heating power.
For example, the thermal management problem of the missile-borne seeker becomes a key technical problem for the performance development of high-end equipment, taking a gallium nitride TR transceiver component widely used in the missile-borne seeker as an example, the heat flux density of a single-channel chip is approximately 100W/cm 2, the heating power consumption of the module is hundreds of watts to kilowatts, during the flying and cruising process of the missile, the temperature of the shell of the missile is usually more than 200 ℃ due to the pneumatic heating caused by high-speed flying, and the heating of the internal chip cannot be emitted to the outside, and certain heat insulation measures are required to prevent the pneumatic heating of the outside from affecting the normal operation of an internal single machine. At this time, it is an ideal solution to store the heat generated by the internal chip temporarily.
The energy storage type heat control device can absorb a large amount of heat in the solid-liquid phase change process through the working medium in the cavity, so that the heat which cannot be dissipated is temporarily absorbed and stored in a short time or periodically. Common energy storage materials such as alkanes, crystalline hydrated salts, fatty acids and polyols have good phase change latent heat, but all have the problem of poor heat conduction capacity, and the problems of low heat absorption speed, slow energy storage response and insignificant temperature inhibition effect are brought. The metal phase-change material has the advantages of high heat conductivity, good heat conduction capacity and response rate, but small phase-change latent heat, generally only 20-80KJ/kg, and the problems of high heat absorption capacity, small capacity and high material weight.
