[0002] With the large-scale application of high-power electronic devices, its heat dissipation problem has been concerned by everyone. High-power electronic devices are composed of multiple switching tubes, which are limited by the heat transfer performance of metal materials, such as copper (390W / m·k), and there is still a large temperature difference between the shell temperature and the junction temperature of high-power electronic devices. The cold end hopes to have a large temperature difference with the environment temperature to improve the heat exchange performance of the heat sink; and the junction temperature of high-power electronic devices cannot be too high, and for most high-power electronic devices, the junction temperature is limited to 125℃. Therefore, reducing the temperature difference between the die and the shell is the most effective method.
[0003] Missiles and other weapons have many electronic devices, such as radar homing heads, which will generate a large amount of heat during operation. Moreover, the working environment of these electronic devices is particularly harsh, often high-temperature environment, which causes the heat generated by these devices to be unable to exchange with the outside world, and the long-term high-temperature heat exchange causes electronic device failure. The conventional air cooling and water cooling structure is not suitable for use in these missile-borne electronic devices. Therefore, for missile-borne electronic devices such as radar homing heads, a structure is needed to store and transfer heat to electronic devices without relying on external air cooling and water cooling.

[0023] In the above technical solution, the phase change medium paraffin wax is used as a heat storage and heat conduction material, when the electronic device releases a large amount of heat, the paraffin wax absorbs heat and stores heat, and when the temperature decreases, the paraffin wax releases heat again, thereby achieving the effect of heat storage and heat transfer.

[0027] According to a preferred embodiment of the present application, the inner side wall of the heat storage tank is paved with a heat-conducting layer, one end of the main fin close to the outside is connected to the heat-conducting layer, the heat-conducting layer and the heat storage tank are directly in large-area contact, and the heat-conduction efficiency is higher.
