Heat Pipe Solar Collector
The heat pipe solar collector is an important part of a split pressurized solar system. It is made of high efficiency pipe and glass vacuum tubes with a 94% heat absorption factor. This solar collector is separate from the water tank which makes it much lighter, and gives it a more attractive appearance. Split pressurized solar systems are currently very popular in Europe, America and Australia, where they are typically positioned on the roof or in a garden.
The heat pipe solar collector system uses pressurized vacuum tubes which transfer solar energy to a main heating pipe. The vacuum tubes contain a copper pipe which is filled with liquid. When the pipe is heated, the liquid inside it vaporizes and rises up to the condenser at the top, transferring the heat to the water passing through it. The cooled vapor then becomes liquid again, refilling the tube, which restarts the process.
