Heat pipe is a new heat transfer element with high thermal conductivity. It transfers heat through the evaporation and condensation of the liquid in the fully closed vacuum tube. It uses the fluid principle such as siphoning to play a good cooling effect. It has the characteristics of high thermal conductivity, good isotherm, heat transfer area on both sides of cold and hot can be changed arbitrarily, heat transfer can be conducted from a distance, and the temperature can be controlled.

Heat pipe has the following advantages:

● Heat pipe cooling technology has the advantages of good cooling effect, relatively small thermal resistance, long service life, fast heat transfer. The thermal conductivity of heat pipe is more than 100 times that of common metal.

● Reversible heat transfer direction, no matter any end can become the evaporation end and condensation end;

● Excellent thermal responsiveness. The steam vaporized in the heat pipe can be transmitted close to the speed of sound, so as to effectively improve the thermal conductivity.

● Simple and compact structure, light weight, small volume, easy maintenance;

No power consumption, no noise, in line with the requirements of industrial "green";

● Can be used in the environment without gravity field.
