The heat pipe technology is to transfer the heat of a heating object to the outside of a heat source through a heat pipe by utilizing the heat conduction principle and the rapid heat transfer property of a refrigerating medium. The heat pipe utilizes evaporation refrigeration to make the temperature difference between two ends of the heat pipe great, and then the heat is transferred rapidly. The heat pipe is mainly composed of a pipe shell, a liquid absorption core and an end cover, wherein the interior of the heat pipe is pumped into a negative pressure state and is filled with proper liquid, and the liquid has a very low boiling point and is easy to volatilize. The tube wall has a wick that is constructed of a capillary porous material. When one end of the heat pipe is heated, the liquid in the capillary is quickly evaporated, the steam flows to the other end under a small pressure difference and releases heat to be condensed into liquid again, and the liquid flows back to the evaporation end along the porous material under the action of capillary force.
