Self-triggering liquid-gas phase change heat dissipation module

The invention relates to a self-triggering liquid-gas phase change heat dissipation module, and relates to the field of heat dissipation of missile-borne electronic equipment.The self-triggering liquid-gas phase change heat dissipation module comprises a shell, a self-triggering material and a phase change material, the shell is internally provided with a phase change material cavity, the phase change material is located in the phase change material cavity, the outer wall of the shell is provided with an exhaust port, and the exhaust port and the phase change material cavity are communicated through a self-triggering channel; the self-triggering material is blocked in the self-triggering channel, the liquefaction temperature of the self-triggering material is higher than the vaporization temperature of the phase-change material, and the phase-change material is in a liquid state at normal temperature. The high-power phase-change heat dissipation module has the beneficial effects that the long-time rapid therm
