When the solar heat collector is used specifically, sunlight penetrates through the light transmitting layer 5 to irradiate the heat absorbing layer 6, heat of solar energy is absorbed, and because the two layers of glass are vacuum heat insulation, the heat cannot be transmitted outwards and can only be transmitted to water in the heat collecting tube, so that the water in the heat absorbing layer is heated. The heated water is lightened and upwards enters the water tank 4 along the heating surface of the heat collecting pipe, at the moment, the hot water pushes the spiral plate 7 to rotate, and the water with relatively low temperature in the water tank 4 enters the heat collecting pipe along the backlight surface of the heat collecting pipe for supplement. The water in the water tank 4 is continuously heated by the continuous circulation, so that the purpose of heating water is achieved.
When the spiral plate 7 rotates, the water which should be flowing along at this time becomes turbulent, and the combination of the scale is damaged to a great extent. And the arrangement of the calabash-shaped heat collecting pipe and the partition plate 8 separates hot water from cold water as much as possible, thereby effectively avoiding turbulent flow from influencing the circulation of water flow. Compared with the traditional solar water heater, the solar water heater effectively reduces the scale generated on the inner wall of the heat collecting pipe and increases the heating efficiency of hot water.
