What is the working principle of heat pipe
Heat pipe heat transfer element, this can be single use, can also be combined, according to customer's site conditions, with corresponding circulation structure assembled into various forms of heat exchanger, heat pipe heat exchanger has high heat transfer efficiency, small resistance loss, compact structure, reliable operation and maintenance costs less, and other advantages, it is in space technology, electronics, metallurgy, power, petroleum, chemical industry and other industries widely used.
Typical gravity heat pipe, as shown in the airtight tube first into a vacuum, filling the appropriate working medium under this state, on the lower end of the heat pipe heating, laser vaporization heat absorption for steam, under the small pressure difference, up to the upper heat tube, and gives off heat to the outside world, condenses into liquid. Condensate in under the action of gravity, along the heat pipe wall returns to the heating period, and once again heated vaporization, cycling, continuous heat from one end to the other end. Because is phase change heat transfer, heat pipe heat resistance is very small,
Heat pipe is a kind of high heat conduction performance of the heat transfer element, it through the closed tube shell substance in evaporation and condensation heat transfer, high thermal conductivity, excellent isothermal property, heat transfer area on either side of the hot and cold can be arbitrary change, heat transfer and temperature can be controlled and a series of advantages over a long distance. Made up of heat pipe heat pipe heat exchanger has high heat transfer efficiency, compact structure, small fluid resistance loss, is helpful to control the dew point corrosion, etc.
