The process of the heat pipe: heat pipe is generally a hollow cylindrical tube, which part of the space is filled with an easily evaporating liquid. Always maintain the vacuum state in the tube, while similar among the evaporation of the liquid temperature and ambient temperature. When heat is absorbed volatilization layer, liquid is rapidly heated to the boiling point, and then began to boil, to generate steam, the vapor rises to the cooling layer, when the heat is released, the vapor re-condenses into droplets due to gravity, or other internal role droplets back volatilization layer continues to be evaporated, and then was cooled, which formed one cycle of the loop, to push this cycle is the heat source, that is, the heat pipe where the process principles.

The heat pipe has a very high thermal conductivity, good temperature, hot and cold on both sides of the heat transfer area can arbitrarily change, long-range heat transfer, can control the temperature, etc., was born early are mainly used in the aerospace, military and other industries, and later in metallurgy, chemical industry, transport, machinery and electronic technology industry has a wide range of applications. The heat pipe is now available in the market of high-end PC cooling mainstream configuration components, compared to traditional metal radiator heat pipe radiator with low noise, high-performance technical superiority, as technology continues to mature and large-scale production applications, the price of the heat pipe is also getting easier to accept.
