Description

Technical Field

[0001] The utility model belongs to the technical field of solar energy new energy, and in particular relates to a solar water heater vacuum tube collector tail frame assembly. Background Art

[0002] Water heaters are an indispensable part of the life of residents. At present, the widely used water heaters on the market include electric water heaters, solar water heaters and gas water heaters. Solar water heaters are a heating device that converts sunlight into heat energy. They can heat water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are mainly composed of heat collecting tubes, water storage tanks and brackets and other related parts. The heat collecting tube is the core component, which is responsible for converting solar energy into heat energy. Under sunlight, the heat collecting tube absorbs the heat of sunlight to increase the water temperature. When hot water is needed, it can be transported to the required place through pipes.

[0003] The solar water heaters currently on the market include: solar water heaters with direct heat exchange through direct insertion of the collector tube; solar water heaters with indirect heat exchange through the collector tube with condensing end and evaporating end, and the water tank with blind pipe, such as all-glass heat pipe vacuum collector tube and metal heat pipe vacuum collector tube.

[0004] For indirect heat exchange solar water heaters, when assembling this type of collector tube with the water tank and bracket, due to structural limitations, the tail bracket where the tail of the collector tube is assembled with the bracket is mostly divided into two parts. One part is to insert the cylindrical hole body with a clip into the collector tube, and then assemble it to the tail seat of the bracket, and then screw the other part of the tail cone with a thread into the cylindrical hole body. This tail bracket is suitable for metal heat pipe vacuum collector tubes with shorter condensation ends and smaller diameters. However, for all-glass heat pipe vacuum collector tubes, since the condensation end is relatively long (the shortest is 120mm), the height between the tail seat of the bracket and the ground must be increased, and the installation must be carried out from the bottom of the cylindrical hole body. This not only increases the cost, but also makes installation more troublesome and the structure more complicated. Utility Model Content
