Heat pipe ?

[vnyeu]

would you please tell me what liquid inside the copper tube.... of course it is not solid copper. right?

We provide orignial designed Sydney tubes collectors, running directly with water. EN-12975-1&2 (Solarkeymark) tests made by TÜV Rheinland passed

SUNSHORE = No wasted copper, no pressure, no antifreeze fluid, needed. Just vacuum + H2O = pure energy

etha 0 = 0,76

a1= 1,67

a2= 0,00

Forget heatpipes in sysdney tubes. Its too expensive (copper), reduces general efficiency, due to 4 times dry conduction for heat transfer, aluminium fins contact points on the glas is lower than 1% of surface -> heat transfer from absorber (on glas) to medium only on few spots -> causing hard thermic tension to glas -> microfractures and loss of vacuum -> absorber film vaporates without vacuum to invisibility -> reduces lifetime of the "sydney" glasstube" (normaly ~20 years) to < 3-5 years

Is it still working well.? Looks amazing.

si, it is the condenser portion of the heat pipe. liquid inside the heat pipe heats up and boils, rises to the condenser, where it releases its heat into the manifold (top part of the frame).
