Heat Pipe Solar Collector Introduction The heat pipe system consists of the glass evacuated tube and a copper heat pipe which is installed within the glass tube. The copper heat pipe conducts heat from within the evacuated tube to its tip (condenser) which is plugged into the header pipe contained in the manifold. As water runs through the header pipe heat is transferred from the heat pipe condenser to the water. 1. High heat conduction coefficient: 2000-5000 times of metal materials. 2.High quantity of heat conduction: 1000 times of metal materials. 3.Low temperature difference: less than 4 difference in 2 meter long pipe. 4. Anti-freeze: can work as low as -40oC Feature 1. Reliable, efficient, twin-glass solar tubes heat pipe. 2. Copper heat pipes for rapid heat transfer. - Low maintenance. - Easy installation of single or multiple units. 3. Corrosion resistant silver brazed copper header.

For solar tubes this is defined as the cross-sectional area of the inner tube (selective coated) measured using the outside diameter. (E.g. 0.047 x 1.72m = 0.08m2)
