Problems solved by technology
[0004] When the heat collecting pipe of the solar water heater is connected to the water tank, if the connection is improper, it will hinder the convection of cold water and hot water in the water tank and affect the heat collecting performance
At present, generally for convenience, the heat collecting tubes are directly interspersed in the water tank, and then welded together as a whole. In this way, when the heat collecting tubes are exposed to the sun for a long time, they are prone to damage, which will cause the entire heat collecting tubes and the water tank to be replaced, resulting in a great waste

The invention discloses a solar heat collecting tube connecting structure, and belongs to the technical field of solar energy. The solar heat collecting tube connecting structure comprises a water tank and heat collecting tubes; the water tank comprises a water tank inner liner, a water tank outer liner and an insulation layer; the heat collecting tubes consist of inner and outer layers; the inner layer is black plastic tubes; the outer layer is transparent glass tubes; a thread sleeve is mounted on the outer side of the water tank outer liner through a fastening piece; the heat collecting tubes are inserted in the water tank, and communicate with the internal of the water tank; and rectangular sealing rings and trapezoidal sealing rings are mounted between the thread sleeve and the heat collecting tubes. Firstly, the thread sleeve is mounted at the externals of the heat collecting tubes; then, the thread sleeve is mounted at the external of the water tank outer liner through the fastening piece; and the heat collecting tubes and the water tank are connected without using a welding mode, so that the heat collecting tubes are conveniently disassembled and installed; and through settings of the rectangular sealing rings and the trapezoidal sealing rings, the leakage of water in the water tank can be prevented, and the sealing performance between the water tank and the heat collecting tubes is improved.
Description
technical field [0001] The invention relates to the technical field of solar energy, in particular to a connection structure of solar heat collecting tubes. Background technique [0002] A solar water heater is a device that uses the energy of the sun to heat water from a low temperature to a high temperature, and is a thermal energy product. The solar water heater is composed of glass vacuum heat collecting tubes, water tanks, brackets and related accessories. The conversion of solar energy into heat mainly depends on glass vacuum heat collecting tubes. The temperature of the surface of the heat collecting tube exposed to sunlight is high, and the temperature of the back side of the heat collecting tube is low, while the water in the tube produces a temperature difference reaction. Using the principle of hot water floating up and cold water sinking, the water produces microcirculation to achieve the required hot water. [0003] There are many types of solar water heaters. ...
