The invention discloses a phase change heat storage radiator utilizing the thermal expansion of phase change materials, comprising a top cover, a negative pressure area, a package base, a composite channel tube, an organic phase change material and a cold plate, and the cold plate is arranged on the package base The bottom of the package base is provided with a composite channel tube surrounded by heat pipes and heat insulation tubes. The heat pipe is arranged in the inner layer of the heat insulation tube. Organic phase change material; the invention uses the high pressure generated by the thermal expansion of the phase change material to release the high temperature liquid phase change material near the bottom heat source to the top position, which can effectively improve the efficiency of phase change energy storage, improve heat dissipation performance, and prolong the bomb load Effective protection time of special electronic equipment. And it effectively solves the serious consequences of the failure of electronic equipment due to the leakage of the phase change material due to the expansion of the expansion volume and the rapid increase of the internal pressure after the phase change material is melted.
Description
technical field [0001] The invention relates to the technical field of heat dissipation of electronic equipment, in particular to a phase change heat storage radiator utilizing thermal expansion of phase change materials. Background technique [0002] With the rapid development of society, electronic circuits become more complex, and the operating load continues to increase and develop towards miniaturization. The local heat flux density of equipment during work becomes larger and larger with the increase of integration, and heat dissipation problems are becoming more and more serious. protrude. For missile-borne electronic equipment, it will release more heat in a short period of time. If the heat dissipation cannot be optimized reasonably, the temperature of electronic devices will rise rapidly, causing certain damage to the missile-borne system and seriously affecting the missile-borne electronic equipment. of normal operation. When the temperature exceeds a certain cri...
