U Pipe Solar Collector
U pipe is formed by a straight copper pipe bent into U shape at a certain position. And one end is higher than another end.
U shape pipe line is composed of 2 two pieces transverse parallel water pipes and many vertical equidistance parallel U shape pipes.
U shape pipe solar collector is composed of U shape water pipe line, humid protection layer, vacuum tube and the frame. It consists of the vacuum solar collection tube, U shape metal tube and the sheet metal. The U shape metal tube is put into the vacuum solar collection tube and the top end of the U shape metal tube extends out of the collection tube nozzle. The sheet metal is put in the vacuum solar collection tube and is fixed with one vertical metal tube. Because of this, it will have the temperature of the water in the vertical tubes at this side higher than that at the other side and it will automatically generate the flow power between the cold water and the hot water. It makes the collector excellence of good water cycle, high heat exchange efficiency, no bursting and no water leakage. At the same time, because of the simple structure of the U shape metal tube, it¡¯s cost is much lower than the heat tube. So it is a cheap product with high quality. It could be united with the water tank together to be a integerated type solar water heater. And it also could be apart from the water tank to form the separate type solar water heater.
The collection tube of the U shape tube solar collector is composed of the vacuum solar collection tubes, heat transferring aluminum vane and the U shape copper tubes. There is the heat transferring medium in the copper tube. It absorbs heat from the vane directly to cycle the heat transferring. Same as the dry evaporating solar collector, even there is the bursting of the tube, but it still could be used because there is no water in the vacuum tube.
U shape tube solar collector is composed of the full glass vacuum solar collection tube, U shape copper tubes, aluminum vane and the bracket. The |
