DC tube is a concentric small diameter copper tube with a diameter slightly larger concentric brass combination. Two parallel transverse vertical take root and several pipes in parallel, equally spaced concentric arrangement of the DC tube that is composed of concentric tube collector current water way to go. Concentric tube collector DC current by concentric tubes to go water pipeline, insulation, vacuum tube and the collector frame and other components. Concentric tube collector collector current principle: This product is solar-powered vacuum tube absorbs solar energy, heat transfer to go through the aluminum fin copper tube outside the water, the water under the action of the circulation pump from the inlet to enter through the copper tube and then take the water flows through the outer copper tube, into the water, thus taking the heat collector, heat storage tank into. DC concentric tube collector has the following advantages: â–² vacuum tube does not go in water, does not scale, long-term use does not affect the collection efficiency; â–² angle limits are not installed, can also be placed horizontally heel, that the balcony wall; â–² pressure can be used for non-pressure dual-use; â–² concentric tube and aluminum fin heat transfer from the DC tube with the power outages, bad case of the pump hot and cold copper pipes will not impact deformation and bursting tube; â–² tube occasionally damage does not affect the whole operation; â–² steel connection system uses no silicone ring to bring the aging, leaking phenomenon; â–² heat transfer by circulation of liquid forced circulation pump, high efficiency; 8, can be series or parallel into large collector works;
