Heat collecting and transferring apparatus and systems adapted for use with solar energy

摘要

Heat energy as from solar rays is collected by units including transparent plates covering a completely liquid filled chamber which has a heat absorbing layer as the internal surface of the chamber. The liquid is transparent and capable of absorbing, storing and/or transporting the heat energy. In one embodiment, the heat is removed to a storage tank from many such collector units by pumping. The system can allow draining of the collector when heat collection conditions do not prevail. In another embodiment of collector, the heat is transferred through the heat absorbing walls and the liquid medium acts mainly as a heat receiver and storing facility. A compartmentalized tank can be employed to enhance heat collection efficiency.
