Heat Pipe Gravity
Heat pipe is a heat transfer element with high thermal conductivity. It transfers heat through the evaporation and condensation of working medium in the fully enclosed vacuum tube shell. It has a series of advantages, such as high thermal conductivity, good isothermal, arbitrary change of heat transfer area on both sides of cold and hot, remote heat transfer, temperature control and so on.
The heat pipe heat exchanger composed of heat pipes has the advantages of high heat transfer efficiency, compact structure, small fluid resistance loss, conducive to controlling dew point corrosion and so on. At present, it has been widely used in metallurgy, chemical industry, oil refining, boiler, ceramics, transportation, light textile, machinery and other industries. As an energy-saving equipment for waste heat recovery and thermal energy utilization in the process, it has achieved remarkable economic benefits.

For a typical gravity heat pipe, a vacuum is first drawn in the closed pipe. In this state, an appropriate amount of working medium is filled and heated at the lower end of the heat pipe. The working medium absorbs heat and vaporizes into steam. Under a small pressure difference, it rises to the upper end of the heat pipe, releases heat to the outside and condenses into liquid.
Under the action of gravity, the condensate returns to the heating section along the inner wall of the heat pipe and is heated and vaporized again. In this way, the heat is continuously transmitted from one end to the other end.

The heat pipe can be used alone or in combination. According to the conditions of users, it is combined with corresponding flow structure into various forms of heatsinks. It has many advantages, such as high heat transfer efficiency, small resistance loss, compact structure, reliable operation and low maintenance cost. It has been widely used in various industries such as space technology, electronics, metallurgy, power, petroleum, chemical industry and so on.
