SOLAR COLLECTOR

A bank of evacuated tubes with copper core transmitting energy into the header tube coolant.

Evacuated Tubes

Rain, wind and cold have minimal negative effect.
Very strong vacumn.
Solar energy absorbing film.
Silvering is a chemical process to give the vacuum its full strength.
Heat tube.
Partial vacumn.
Fluid evaporates and condenses.
Foil conductor.

Manifold

Conductive paste.
Cold in, hot out
Energy passes from the heat tube and into the coolant of the closed circuit.
