DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

The integrated solar thermal collector 5 is arranged on the placement plate 1 through the automatic rotating support structure 2. The integrated solar thermal collector 5 is controlled to rotate automatically in the horizontal direction according to the position of the sun in a day through the automatic rotating support structure 2, so that the working surface of the integrated solar thermal collector 5 always faces the sun; the photovoltaic components of the integrated solar thermal collector 5 are controlled to swing in the vertical direction through the automatic rotating support structure 2; in the summer when the ambient temperature is high, according to the surface temperature detection of the integrated solar thermal collector, before the temperature rises to the set high temperature, the integrated solar thermal collector performs photovoltaic power generation. After the temperature rises to the set temperature, when the photovoltaic power generation efficiency of the integrated solar thermal collector is reduced due to the high temperature, the automatic rotating support structure 2 rotates itself and controls the heat-conducting focusing arc plate 24 to flip to face the sunlight for photothermal conversion. In the winter when the ambient temperature is low, the integrated solar thermal collector 5 generates electricity only through the photovoltaic components and transfers the heat generated by the photovoltaic components to the heat-conducting water tank 31 through the flexible loop heat pipe 4 in the heat-conducting focusing arc plate 24.

[0030] The integrated thermal management system of light, heat and electricity also includes a water supply and power generation structure, which includes a water supply machine 6, a transfer box 8, a generator 12 and a thermoelectric generator 16.

The other end of the rotating rod 9 is connected to a generator 12.

[0032] The adapter box 8 is provided with a water pipe 7, and the direction of the water pipe 7 is the same as the direction of the water flow at the water outlet of the adapter box 8, so as to ensure that the fan blades 11 can effectively push the rotating rod 9 to rotate when water flows through.

[0033] The water conduction water tank 31 is provided with a water outlet pipe 19 through which water is supplied to users.

[0034] The integrated thermal management system of light, heat and electricity also includes a cold water tank 20, on which a cold water inlet pipe 23 and a cold water outlet pipe 22 are provided. The cold water outlet pipe 22 is provided with a solenoid valve 21 and is connected to the water supply pipe 19, so that the hot water in the hot water tank 31 and the cold water in the cold water tank 20 are mixed; the water temperature is adjusted by controlling the amount of water output from the cold water tank 20.

[0037] The integrated solar thermal collector 5 absorbs the heat of sunlight and transfers the heat to the water-conducting water tank 31 through the flexible loop heat pipe 4 to heat the water. Since the flexible loop heat pipe 4 transfers the heat, the photovoltaic module of the integrated solar thermal collector 5 will not be damaged due to excessive temperature, thereby extending the service life. At the same time, the photovoltaic module generates electricity and stores the electricity in the storage battery 17. When water is needed, the water wheel structure is driven to rotate by the flow of water, thereby driving the generator 12 to generate electricity, and the generated electricity is also stored in the storage battery 17. The thermoelectric generator 16 is provided to absorb the heat generated by the integrated solar thermal collector 5, the generator 12 and the storage battery 17, thereby generating electricity and storing it in the storage battery 17. During the day, the water in the water conduction water tank 31 is directly heated by the integrated solar thermal collector 5; when the temperature is low during the day or there is no sunlight at night, the water in the electric water tank 32 is heated by the heater 18 using the electric energy generated by the integrated solar thermal collector 5, the generator 12 and the thermoelectric generator 16 and stored in the storage battery 17. The integrated thermal management system of the utility model can be applied not only to the field of civil water heaters, but also to other thermal management system fields.
