Dual-vacuum Solar Tube

We are instrumental in providing to our valuable customers excellent quality Dual-Vacuum Solar Tube which is available with following Features:-

1. Superior thermal conductivity. In the heat tube, the heat is transferred mainly by phase change of the working liquid and the flowing of the steam, the thermal resistance is small, so that the heat tube has quite high heat conducting capability; and compared with the metal with higher heat conductivity such as silver, copper, aluminum, etc., the heat tube with unit weight can transfer more heat;

2. Superior isothermal property. The steam in the inner cavity of the heat tube stays in the saturated state, so when the steam flows from the evaporation section to the condensing section, there is little pressure drop as well as temperature drop;

3. Variable density of heat flow. The density of heat flow in the inner tube can be changed by modifying the heating surface of the condensing section or the evaporation section.
