Specifications
heat pipe solar collector being described belows:
The heat pipe solar water collector series are always connected with
existing heating supply device.The selective coating on the inner cover or the
evacuated tubes converts solar energy into heat energy and transfers heat the
heat pipes by aluminum finsl.
