Background
The heat pipe technology is widely applied to the industries of aerospace, military industry and the like, and is introduced into the radiator manufacturing industry, so that people change the design idea of the traditional radiator and get rid of a single heat radiation mode of obtaining a better heat radiation effect by only depending on a high-air-volume motor. The heat transfer of the heat pipe is to utilize the phase change process of the medium after the medium is evaporated at the hot end and condensed at the cold end (namely, the latent heat of evaporation and the latent heat of condensation of the liquid) to quickly conduct the heat. The heat pipe is composed of pipe shell, liquid absorbing core and end cover, the interior of the heat pipe is pumped into negative pressure state and filled with proper liquid, one end of the heat pipe is evaporation end, the other end is condensation end, when one end of the heat pipe is heated, the liquid in the capillary tube is vaporized rapidly, the vapor flows to the other end under the power of heat diffusion and is condensed at the cold end to release heat, and the liquid formed after liquefaction flows back to the evaporation end by capillary action. Because the circulation at the two ends of the heat pipe is performed quickly, the heat can be quickly transmitted to the outside through the heat pipe, and the temperature can be effectively reduced.
However, the continuous update of high-power electronic products has brought about the problem of high heat flux density along with the increase of the operating speed of electronic chips, which has seriously affected the working performance and stability of electronic devices. For high-power electronic products, the heat transfer efficiency of most heat pipes in the current market cannot meet the heat dissipation requirement of the electronic products, so that the products cannot exert the normal working efficiency.
