Application of a heat pipe on the thermal module
 

A heat pipe is an efficient heat transfer device commonly used for cooling an electronic component. A heat pipe is essentially closed, evacuated tube lined with a porous structure called "wick structure" (for CCI by screen wick). The wick is saturated with a proper amount of working fluid (for CCI by pure water).

The liquid phase of the working fluid contained in the wick structure absorbs thermal energy from the heated scetion and becomes vapour filling the heat pipe chamber. Then the dissipation of the thermal energy at the condensing section causes the vapour to release the latent heat and condense. The condensed working fluid is then sucked back to the evaporating section along the wick structure through the capillary force.

This thermodynamic cycle continues as the thermal energy is transformed from one section of the heat pipe to another. It is noted that the temprature will remain constant as the working fluid goes through the phase change inside the heat pipe chamber. This phenomenum makes the heat pipe a very efficient heat transfer device. Under the same thermal load conditions, the thermal conductivity of a heat pipe can be a hundred times higher than that of a copper rod with the same cross-sectional area and length.

With it;s excellent performance and superior thermal characteristics, a CCI haet pipe will keep your CPU or the device you want to protect cool and running smoothly.
