Additional Details

In an Evacuated tube collector, the absorber strip is located in an evacuated and pressure proof glass tube. The heat transfer fluid flows through the evacuated tube. Several single tubes, serially interconnected, or tubes connected to each other via manifold, make up the solar collector. A heat pipe collector incorporates a special fluid which begins to vaporize even at low temperatures. The steam rises in the individual heat pipes and warms up the carrier fluid in the main pipe by means of a heat exchanger. The condensed liquid then flows back into the base of the heat pipe.
