A Solar Super heat pipe employs an evaporating-condensing cycle, which accepts heat from an external source, uses this heat to evaporate the liquid (latent heat) and then releases latent heat by reverse transformation (condensation) at a heat sink region. This process is repeated continuously by a return feed mechanism of the condensed fluid back to the heat zone. In the solar collector, the condensation zone is at a higher level than the evaporation zone. The transport medium condensed (in the condensation zone) returns to the evaporation zone under the influence of the gravity. Then, there is no need of capillary wick structure.
The maximum operating temperature of a heat pipe is the critical temperature of the used heat transfer medium. Since no evaporation/condensation above the critical temperature is possible, the thermodynamic cycle interrupts when the temperature of the evaporator exceeds the critical temperature.
1. High Heat Conduction Coefficiency is 2000-5000times of metal materials
2. High Quality of Heat Conduction is 1000times of metal materials
3.Lower Temperature Difference: less than 2C difference in 2Meters long heat pipe.
