Solar Water Heater Generally information:
1. LUCKY - Solar Water Heater working principle:
The vacuum tube absorb the solar ray and conduct the heat to heat-pipe (inside) by the aluminum slice, because the heat-pipe is connected with the copper connector which in the water tank, so there exists heat exchanging between the heat- pipe and copper connector, when the heat exchanging goes on, the water in the tank will be heated and become hot water.
2. Advantage of LUCKY - Solar Water Heater:
1. Pressurized system ensure to provide strong water flow for shower
2. This type doesn’t need any controller, circulation pump, expansion pump. Feeder tank, it also can supplement cold water automatic
3. We use the advanced ring-argon arc welding .ensure the high quality.
4. Thickness of inner tank: 1.2mm-2.0mm food grade SUS304 stainless steel
5. Even there is a tube broken; the system can work in a good condition
6. This type is cheaper and easy install than the separated pressurized solar water heater. i think it will popular and have a good market .
3. The Heat pipe - Evacuated tube:
A heat pipe works as a solar energy absorber inside the evacuated tube and transfers the absorbed solar energy to a working vaporizable fluid. When the heat pipe reaches 30ºC, the fluid will vaporize. This vapor rapidly rises to the top of the heat pipe transferring heat to the condenser. As the heat is lost at the condenser, the vapor condenses to form a liquid and returns to the bottom of the heat pipe. Then the evaporating-condensing cycle process starts again.
4. Solar evacuated tube heat pipe internals:
A further, very important factor in selecting your evacuated tube collector is the quality of the internal heat-transfer-fin as this is often overlooked and generally very thin or poorly formed to cut costs, or is even 2 or 4 separate pieces. All this will ultimately reduce the efficiency of your collector, and as such your electricity saving.
