Problems solved by technology
Air natural convection cooling and forced air cooling are low in cost, but low in heat dissipation efficiency; heat pipe heat dissipation technology uses phase change and internal capillary action of heat pipe to drive internal working medium flow, which has a good cooling effect, but the complexity of its internal structure makes heat pipe Under the ultra-thin structure, the capillary structure is easily damaged, which affects the heat dissipation capacity, and when the heat flux exceeds the heat capacity limit of the heat pipe, the internal working fluid will evaporate and lose the original heat transfer effect.

Abstract
The invention relates to a liquid-cooling heat radiation system and electronic equipment, and belongs to the technical field of heat radiation. The heat radiation system arranged on a heat source comprises a circulation loop which penetrates the heat source and internally includes liquid metal, a pump arranged in the circulation loop and used to enable the liquid metal in the circulation loop to flow in a cycled manner, and a radiator arranged in the circulation loop. According to the liquid-cooling heat radiation system and electronic equipment, the liquid metal instead of routine fluids as deionized water serves as a circulation medium, the heat conduction coefficient of the liquid metal is much higher than that of the deionized water and the viscosity of the liquid metal is low, so that the heat conduction coefficient and circulation flow of the working medium are improved and further the heat radiation capability of the whole liquid cooling heat radiation system is improved effectively; and the electromagnetic pump drives the liquid metal to flow, the pump structure is compact, miniaturization is easy to realize, rotation parts are not needed, problems as wearing of mechanical pumps is avoided, and the reliability of the heat radiation system is improved.
Description
technical field [0001] The present disclosure relates to the technical field of heat dissipation, and in particular to a liquid cooling heat dissipation system and electronic equipment. Background technique [0002] With the continuous development of electronic technology, the integration of electronic products is getting higher and higher, the frequency is getting faster and higher, and the power is getting higher and higher, which makes the demand for heat dissipation technology with high efficiency and good performance increasingly urgent. [0003] Traditional heat dissipation methods include air natural convection cooling, forced air cooling, heat pipe cooling and liquid cooling. Air natural convection cooling and forced air cooling are low in cost, but low in heat dissipation efficiency; heat pipe heat dissipation technology uses phase change and internal capillary action of heat pipe to drive internal working medium flow, which has a good cooling effect, but the comple...
