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 solar collector is apart from the water tank and the solar radiant energy will be translated into heat energy by the heat transferring medium in the U shape copper tubes and be transferred to the water tank by the heat exchanger. Parallel connection or series-wound connection may be applied to form the solar collection system with? different daylighting area.? To work with other general energy, it can make the water heating system work all the day. Even there is no water in the vacuum tube, if there is the bursting of the tube, the solar collection system still will work as usual. The heat transferring medium could be antifreeze. It could work in very cold area in different seasons. The solar collection tubes could be installed in series or in parallel connection. The working pressure of the system is up to 6kg f/stere. There is no direction limitation for arranging the tubes. It is easy to install and maintain. If fixed with controller, auto running of the system could be carried out.
