[0038] Solar energy is an inexhaustible source of green and clean energy. The rational and effective development and utilization of solar energy resources has become an important way for my country to solve the energy crisis, alleviate climate change and environmental pollution. At present, my country has gradually developed and utilized solar energy, but solar energy devices are usually installed in open suburbs, which requires a large installation area. At the same time, the use of solar energy devices only realizes the full utilization of light energy, but cannot fully utilize heat energy, which results in a waste of solar energy resources.

[0039] The present invention provides a solar-electric-thermal integrated synchronous conversion system. Figures 1 to 6 This is an embodiment of the solar-electric-thermal integrated synchronous conversion system proposed by the present invention.

The electric energy utilization component 3 is used for electrically connecting the photovoltaic component 31.

[0041] In the technical solution of the present invention, the heat pipe 11 absorbs the heat energy of sunlight, and then the heat energy utilization component 2 is used to exchange heat with the heat pipe 11 to realize the utilization of the heat energy of sunlight. The heat pipe 11 has an installation surface facing the sunlight, and a photovoltaic component 31 is provided on the installation surface. The photovoltaic component 31 absorbs the light energy of sunlight and converts the sunlight energy into electrical energy. The solar energy is utilized by the electrical energy utilization component 3 electrically connected to the photovoltaic component 31, thereby realizing the full utilization of both the light energy and the heat energy of the sun, and solving the problem of waste of solar energy resources.

[0042] See also Figure 3 In the present embodiment, the heat pipe 11 comprises a heat pipe body, in which a cavity 111 extending along the length direction thereof is formed, and a plurality of the cavities 111 are arranged at intervals along the width direction of the heat pipe 11. By storing a phase change liquid in the cavity 111 and utilizing the characteristics of the phase change liquid having a low boiling point and being volatile, when the heat pipe 11 is heated, the phase change liquid evaporates and can absorb a large amount of heat energy from sunlight. Furthermore, because there are a plurality of cavities for storing the phase change liquid in the heat pipe body, the ability of the heat pipe 11 to absorb heat energy from sunlight is improved.

[0043] See also Figure 4 In order to make full use of the thermal energy of sunlight, in this embodiment, a plurality of heat pipes 11 can be provided, and a plurality of photothermal absorption components 1 can also be provided.

[0045] See also Figure 2 and Figure 4 Specifically, the heat pipe 11 is extended in the vertical direction, and the heat pipe 11 has an evaporation section 11a located at the upper end of the heat pipe 11; in the evaporation section 11a, the phase change liquid in the cavity 111 evaporates and changes into a gaseous state due to the effect of solar thermal energy. The heat energy utilization component 2 includes a heat exchanger 21, and the heat exchanger 21 includes a heat exchange tube 211 arranged on the evaporation section 11a, and a heat exchange liquid flows in the heat exchange tube 211 for heat exchange with the evaporation section 11a.

[0046] Further, in order to improve the heat exchange efficiency between the heat pipe 11 and the heat exchange pipe 211, please refer to Figure 2 In the present embodiment, the evaporation section 11a of the heat pipe 11 is recessed in a direction pointing toward the mounting surface to form a holding arm 11b, and the holding arm 11b is configured to hold the heat exchange tube 211. The heat exchange tube 211 is held by the holding arm 11b, thereby increasing the contact area between the heat pipe 11 and the heat exchange tube 211, thereby improving the heat exchange efficiency between the heat pipe 11 and the heat exchange tube 211.

[0047] In order to strengthen the connection between the holding arm 11b and the heat exchange tube 211 and enhance the heat transfer between the heat pipe 11 and the heat exchange tube 211, a thermal conductive adhesive 4 is provided between the holding arm 11b and the matching section of the heat exchange tube 211. The heat pipe 11 and the heat exchange tube 211 are bonded together by the thermal conductive adhesive 4. The heat transfer between the heat pipe 11 and the heat exchange tube 211 is enhanced by utilizing the thermal conductive properties of the thermal conductive adhesive 4.

[0048] It should be noted that the thermally conductive adhesive 4 may be composed of a thermally conductive material, an alkane liquid dispersant, an adhesive, an activator, and the like.

[0049] For the heat exchange tube 211, the heat exchange tube 211 includes a plurality of heat exchange tube sections arranged on the evaporation section 11a, and the plurality of heat exchange tube sections are arranged at intervals in the up and down directions. The plurality of heat exchange tube sections are utilized to perform heat exchange with the evaporation section 11a, thereby increasing the contact area between the heat exchange tube and the evaporation section 11a and improving the efficiency of heat exchange.

[0050] In order to reduce heat loss, facilitate installation and reduce installation space, refer to Figure 4 , along the width direction of the heat pipe 11 , the inlet 211 a and the outlet 211 b of the heat exchange tube 211 are arranged on the same side.

[0051] In order to place the heat exchange tube 211 and reduce the heat energy loss during the heat exchange process of the heat exchange tube 211, refer to Figure 2 In this embodiment, the heat exchanger 21 further includes a mounting seat 212 and a thermal insulation filler 213. The mounting seat 212 has a mounting cavity 2121 extending along the width direction of the heat pipe 11, and the mounting cavity 2121 is used to place the heat exchange tube 211. The thermal insulation filler 213 is filled in the mounting cavity 2121, and the thermal insulation filler 213 is arranged to cover the heat exchange tube 211. The thermal insulation effect of the thermal insulation filler 213 is utilized to reduce the heat energy loss of the heat exchange tube 211 during the heat exchange process.

[0052] Specifically, see Figure 1-Figure 2 The heat energy utilization component 2 also includes an insulated water tank 22; the inlet 211a of the heat exchange pipe 211 is connected to the heat exchange outlet of the insulated water tank 22, and the outlet 211b is connected to the heat exchange inlet of the insulated water tank 22. The heat exchange pipe 211 is used to exchange heat with the heat pipe 11, and the low-temperature water flowing out of the heat exchange outlet of the insulated water tank 22 is input into the heat exchange pipe 211 for heat exchange heating, and then the high-temperature water heated by the heat exchange pipe 211 is input into the heat exchange inlet of the insulated water tank 22 and enters the insulated water tank 22, so that the water in the insulated water tank 22 is circulated and heated for use, thereby realizing full utilization of solar thermal energy.

[0053] It should be noted that the heat exchange tube 211 is provided with multiple sections; the inlet 211a and the outlet 211b of the heat exchange tube 211 are provided on the same side; the heat exchanger 21 also includes a mounting seat 212 and a thermal insulation filler 213; the heat energy utilization component 2 also includes an insulated water tank 22, and the water inlet and the water outlet of the insulated water tank 22 are both connected to the heat exchange tube; the evaporation section 11a of the heat pipe 11 is recessed to form the holding arm 11b extending in the left and right directions, and other features can be selected to be set one by one, or both can be set at the same time.

[0054] To convert light energy into electrical energy, see Figure 3 The photovoltaic module 31 includes a photovoltaic cell 311 bonded to the heat pipe 11. Furthermore, because the photovoltaic module 31 is arranged on the installation surface facing the sunlight, the absorption of solar energy by the photovoltaic cell 311 is increased, thereby improving the utilization of solar energy.

[0055] It should be noted that, in the present embodiment, the photovoltaic cell 311 is a photovoltaic cell 311 of flexible thin film EVA. Since the photovoltaic cell 311 of flexible thin film EVA is less affected by temperature and can withstand high and low temperature differences, the photothermal absorption component 1 can be applied to various environments. In addition, even in weak light conditions, the photovoltaic cell 311 of flexible thin film EVA can convert light energy into electrical energy, so that the use of the photovoltaic component 31 is no longer restricted by weather.

[0056] In order to convert the direct current generated by the photovoltaic cell 311 into alternating current for use by electrical equipment, specifically, refer to Figure 1 The electric energy utilization component 3 includes an inverter 32 , and the inverter 32 is electrically connected to the photovoltaic cell 311 .

[0057] In order to prevent the light-heat absorption component 1 from being exposed to wind and rain and shortening its service life, please refer to Figure 6 The solar thermal electric integrated synchronous conversion system also includes a light-transmitting mounting member 5, which includes a first glass plate 51 and a second glass plate 52. A clamping cavity 53 is formed between the first glass plate 51 and the second glass plate 52. By installing the light-heat absorption component 1 in the clamping cavity 53, the light-heat absorption component 1 is prevented from being exposed to the natural environment, which reduces the service life of the light-heat absorption component 1 and reduces the cost of maintaining the light-heat absorption component 1.

[0058] It should be noted that, in this embodiment, the light-transmitting mounting member 5 is composed of a glass plate, and the light transmittance of the glass plate is utilized so that the light energy of sunlight can be fully utilized. In other embodiments, the light-transmitting mounting member 5 can also be a transparent rubber plate, etc.

[0059] In addition, the heat pipe 11 includes a heat pipe body, in which a plurality of cavities 111 are arranged at intervals, and the solar thermal electric integrated synchronous conversion system also includes a light-transmitting mounting component 5, in which a clamping cavity 53 is formed. Either one of them can be selected or both can be possessed.

[0060] Specifically, a support plate 54 is arranged between the first glass plate 51 and the second glass plate 52, and the first glass plate 51 and the second glass plate 52 are separated by the support plate 54 to form a clamping cavity 53 for installing the light heat absorption component 1. A partition 55 is arranged at the lower end of the clamping cavity 53, and the partition 55 includes a base 551, a desiccant 552 and a sealing member 553. The base 551, the desiccant 552 and the sealing member 553 are arranged in sequence along the upper and lower directions. The base 551 is used to install the light heat absorption component 1, and the desiccant 552 is used to absorb water vapor in the clamping cavity 53. The clamping cavity 53 is sealed by the sealing member 553, and a cushion block 56 is further arranged in the clamping cavity 53. The cushion block 56 is clamped between the second glass plate 52 and the light heat absorption component 1, and the light heat absorption component 1 is supported by the cushion block 56 to prevent the light heat absorption component 1 from shaking when installed in the clamping cavity 53.

[0061] In order to increase the area of ​​the photothermal absorption component 1 receiving sunlight, in this embodiment, the solar thermal electric integrated synchronous conversion system also includes a frame structure 6, which is used to install the photothermal absorption component 1 so that the photothermal absorption component 1 is tilted in a direction away from the sunlight.

[0062] It should be noted that the frame structure 6 can be a building curtain wall frame. By fixing the photothermal absorption component 1 on the building curtain wall frame, the solar thermal integrated synchronous conversion system is combined with the building. Of course, the frame structure 6 can also be a door and window frame, and the photothermal absorption component 1 is fixed on the doors and windows.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
