However, if a circulation power device, such as a circulating water pump, is used to achieve water circulation, it is necessary to connect the circulation power device to the mains power and add a mains power control device, making the construction and installation process even more cumbersome.

[0031] Please see Figures 1 to 8 This utility model provides a self-driven integrated solar thermal collector, including a shell 100, a heat collection component 200, a circulation component 300, and a photovoltaic component 400. The shell 100 includes a housing 110, a partition plate 120, and a transparent cover plate 130. The housing 110 has an opening 101 and a cavity 102, with the opening 101 communicating with the cavity 102. The partition plate 120 is disposed within the cavity 102, with its two ends abutting against the opposite side walls of the cavity 102 to divide the cavity 102 into a first space 103 and a second space 104. The heat collection component 200 includes a heat absorption plate 210 and a pipe structure 2 20. Insulating side plate 230 and insulating bottom plate 240; heat-absorbing plate 210 is disposed at opening 101 and located in the first space 103; pipe structure 220 is disposed in cavity 102 and located on the side of heat-absorbing plate 210 near the bottom wall of cavity 102; pipe structure 220 abuts against heat-absorbing plate; pipe structure 220 has two circulation ports 221 and 222; both insulating side plate 230 and insulating bottom plate 240 are disposed in the first space 103; multiple insulating side plates 230 are disposed and connected end to end, multiple insulating side plates 230 are disposed along the inner side wall of the first space 103, and insulating bottom plate 240 is located on the side of pipe structure 220 near the bottom wall of cavity.

[0032] The circulation component 300 includes a circulation control component 310 and a circulation power component 320; the circulation control component 310 controls the start and stop of the circulation power component, and the circulation power component 320 is connected to the pipeline structure 220 and can drive the circulation medium inside the pipeline structure 220 to flow; the circulation control component 310 is electrically connected to the circulation power component 320 and is used to control the circulation power component 320; the photovoltaic component 400 includes a photovoltaic panel 410 and a connecting wire 420; the photovoltaic panel 410 is disposed at the opening 101 and is located in the second space 104; the connecting wire 420 is electrically connected to the photovoltaic panel 410, the circulation control component 310 and the circulation power component 320 respectively.

[0033] In this embodiment of the invention, the heat-absorbing plate 210 is disposed at the opening 101. Sunlight shines on the heat-absorbing plate 210, which can convert solar energy into heat energy. The pipe structure 220 is located on the side of the heat-absorbing plate 210 near the bottom wall of the cavity 102 and is in close contact with the heat-absorbing plate 210, so that the heat-absorbing plate 210 can conduct heat energy to the pipe structure 220 to heat the circulating medium inside the pipe structure 220. The circulating medium can enter the pipe structure 220 from the circulation inlet 222. The circulating medium inside the pipe structure 220 can be discharged from the circulation outlet 221; the photovoltaic panel 410 is installed at the opening 101, and sunlight shines on the photovoltaic panel 410, which can convert solar energy into electrical energy; the photovoltaic panel 410 is electrically connected to the circulation control component 310 and the circulation power component 320, and provides power to the circulation control component 310 and the circulation power component 320, so that the circulation control component 310 controls the start and stop of the circulation power component 320, thereby driving the flow of the circulating medium inside the pipe structure 220.

[0034] The partition plate 120 is disposed in the cavity 102 of the housing 110. By disposing of the partition plate 120, the cavity 102 can be divided into a first space 103 and a second space 104, so as to separate the heat collection component 200 in the first space 103 and the circulation component 300 and photovoltaic component 400 in the second space 104, thereby preventing the heat energy of the first space 103 from being conducted into the second space 104.

[0035] This invention controls the circulating power component 320 through the circulation control component 310, thereby driving the flow of the circulating medium inside the pipeline structure 220, resulting in higher circulation efficiency. The electrical energy generated by the photovoltaic panel can supply the circulating power component 310 and the circulation control component 320. The circulation control component 310 can control the start and stop of the circulating power component 320, eliminating the need for connection to mains power and additional mains power control devices. This saves costs, makes the system more compact, aesthetically pleasing, and more rationally integrated with modern architecture, and simplifies construction and maintenance.

[0036] Specifically, the circulation control component 310 and the circulation power component 320 are located within the second space 104; the heat absorption plate 210 and the pipe structure 220 are welded together to improve the efficiency of heat conduction; the insulation side plate 230 and the insulation base plate 240 can reduce the heat loss of the heat collection component 200. The self-driven integrated solar thermal collector adopts an integrated structure, with the heat collection component 200, circulation component 300, and photovoltaic component 400 all integrated into the shell 100, avoiding excessive pipe installation. This not only reduces heat loss and improves heat collection efficiency, but also reduces leakage points. While saving costs, it makes the system more compact, optimizes or solves many problems encountered by traditional natural circulation systems and traditional forced circulation systems, has an aesthetically pleasing appearance, and is more rationally integrated with modern buildings. Moreover, construction and operation and maintenance are simpler.

[0037] Specifically, the existing household solar energy system has the disadvantage of natural circulation. Natural circulation has requirements on the position of the water tank and the direction of the pipes. The water tank must be higher than the collector, and the pipes cannot have reverse slopes or sharp bends. The self-driven integrated solar collector of this utility model can solve the disadvantages of natural circulation in household solar energy systems. Through the forced circulation starting speed of the circulation power component 320, its efficiency is also higher than that of natural circulation.

[0038] Compared with traditional natural circulation integrated household solar water heaters, the water tank of this utility model's self-driven integrated solar collector does not need to be installed above its own position to achieve circulation. This reduces the load on the mounting bracket used to install the self-driven integrated solar collector, thereby reducing the concentrated load on the floor and making the use of this self-driven integrated solar collector safer. In addition, the self-driven integrated solar collector has a high degree of integration, is convenient for construction and maintenance, has an aesthetically pleasing appearance, operates rapidly with forced circulation, has higher heat collection efficiency, and less heat loss.

[0039] Compared to traditional balcony wall-mounted solar water heating systems, most existing systems rely on natural circulation. The distance between the water tank and the collector should not be too far, and the water tank must be positioned higher than the collector to achieve circulation. Circulation efficiency is affected by various factors, resulting in low efficiency. Furthermore, the water tank is often suspended from the load-bearing wall of the balcony, increasing the wall load, occupying balcony space, and being unsightly. In contrast, this new self-driven integrated solar collector is not subject to these limitations, operates rapidly, has high thermal efficiency, high integration, and reduces heat loss, making construction and maintenance more convenient. Moreover, the circulation outlet uses a back outlet design, making the circulation pipes invisible from the outside and resulting in a more aesthetically pleasing installation.

[0040] Reference Figures 2 to 5 In some embodiments of this utility model, the housing 110 includes a first back plate 111, a second back plate 112, and side plates 113; multiple side plates 113 are provided and connected end to end; a partition plate 120 is connected to two of the side plates 113; the first back plate 111 is connected to the partition plate 120 and part of the side plates 113 respectively, and the first back plate 111 is disposed in the first space 103 and spaced apart from the heat absorption plate 210; the second back plate 112 is connected to the partition plate 120 and part of the side plates 113 respectively, and the second back plate 112 is disposed in the second space 104 and spaced apart from the photovoltaic panel 410.

[0042] When it is necessary to inspect the pipe component 220 (second pipe component), circulation control component 310, and circulation power component 320, the second back plate 112 can be removed. By setting the second back plate 112, it is convenient to operate the structure in the second space 104.

[0043] Specifically, four side panels 113 are provided, and the four side panels 113 are connected end to end to form a frame structure; the four side panels 113 are arranged opposite each other and spaced apart, and the two ends of the partition plate 120 abut against the opposite end faces of two of the side panels 113 respectively; the first back panel 111 is connected to the three side panels 113 and the partition plate 120, and the second back panel 112 is detachably connected to the three side panels 113 and the partition plate 120.

[0044] Reference Figures 5 to 7 In some embodiments of this utility model, a first opening 114 is provided on two side plates 113; one end of the pipe structure 220 with a circulation outlet 221 passes through the first opening 114 on one side plate 113, and one end of the pipe structure 220 with a circulation inlet 222 passes through the first opening 114 on the other side plate 113; the ends of the pipe structure 220 with the circulation outlet 221 and the circulation inlet 222 are located in the cavity 102.

After being heated by the heat absorption plate 210, the hotter circulating medium in the pipe structure 220 can be discharged from the pipe structure 220 from the circulation outlet 221 of the other side plate 113.

[0046] The end of the pipe structure 220 with the circulation inlet 222 is located at the first opening 114 of the cavity 102, which facilitates the connection of the cold circulation medium pipe to the pipe structure 220. The end of the pipe structure 220 with the circulation outlet 221 is located at the first opening 114 of the cavity 102, which facilitates the connection of the hot circulation medium pipe to the pipe structure 220.

[0047] Specifically, two side plates 113 with first openings 114 are arranged opposite each other, and the ends of the pipe structure 220 with circulation outlets 221 and circulation inlets 222 extend from the side plates 113 on both sides to improve the convenience of accessing the pipe structure 220.

[0049] The cooler circulating medium can enter the pipe structure 220 from the circulation inlet 222 of the second back plate 112. After being heated by the heat absorption plate 210, the hotter circulating medium in the pipe structure 220 can be discharged from the circulation outlet 221 of the second back plate 112 to the pipe structure 220.

[0050] Specifically, the end of the pipe structure 220 with the circulation outlet 221 and the end with the circulation inlet 222 are both located at the second port 115. Through the back outlet, the circulation pipe is not visible from the outside, making the installation more aesthetically pleasing.

[0052] By setting up the insulation side plate 230 and the insulation base plate 240, the heat loss of the pipe structure 220 can be reduced, ensuring the efficiency of the heat absorption plate 210 in heating the pipe structure 220; the connection of multiple insulation side plates 230 end to end can reduce the gaps between them and improve the insulation effect.

[0053] Specifically, the insulation base plate 240 abuts against the end of the plurality of insulation side plates 230 away from the heat absorption plate 210. The insulation base plate 240 is located between the pipe structure 220 and the first back plate 111, so as to reduce the gap between the insulation base plate 240 and the insulation side plates 230, thereby improving the insulation effect.

[0054] Reference Figure 2 and Figure 3In some embodiments of this utility model, multiple heat-insulating side plates 230 are disposed on the inner wall of the first space 103, and the heat-insulating bottom plate 240 is disposed on the bottom wall of the first space 103 and located below the heat-absorbing plate 210, fully filling the first space 103, thereby reducing heat convection and heat radiation, and thus reducing heat loss.

[0055] The insulation base plate 240 and the heat absorption plate 210 are spaced apart, and the pipe structure 220 is located between the insulation base plate 240 and the heat absorption plate 210.

[0056] Specifically, four side panels 113 are provided, and the four side panels 113 are connected end to end. Four insulation side panels 230 are provided, and the four insulation side panels 230 are respectively connected to the partition plate 120, three of the side panels 113 and the insulation bottom plate 240, so that the four insulation side panels 230 enclose to form a frame structure.

[0058] By setting a transparent cover plate 130, the heat absorption plate 210 can be protected, preventing external impurities from directly contacting the heat absorption plate 210, protecting the heat collection component 200, and ensuring the heat absorption effect of the heat absorption plate 210. In addition, the transparent cover plate 130 is transparent and has light transmittance; specifically, the transparent cover plate 130 can have as high light transmittance as possible to maximize the light transmittance, thereby reducing the impact on the absorption of sunlight by the heat absorption plate 210.

[0059] Reference Figure 1 and Figure 4 In some embodiments of this utility model, the periphery of the transparent cover plate 130 abuts against the side wall of the first space 103 and is firmly sealed to protect the heat absorption plate 210 and the pipe structure 220 of the first space 103.

[0061] The circulation control unit 310 is electrically connected to the photovoltaic panel 410. After receiving sunlight, the photovoltaic panel 410 converts solar energy into electrical energy to power the circulation control unit 310 and the circulation power unit 320. The circulation control unit 310 can control the start and stop of the circulation power unit 320. The circulation control unit 310 includes a circulation control structure and a temperature sensing structure that are interconnected. The circulation control structure is electrically connected to the circulation power unit 320. Part of the temperature sensing structure is located in the cavity 102 and can sense the temperature of the pipe structure 220. When the temperature of the heat generated by the heat collection component 200 is compared with the temperature in the heat storage device (heat exchange device), the circulation power unit 310 starts when the temperature difference reaches a set value, and the system operates normally. When the temperature difference is lower than the set value, the circulation power unit 310 stops working (even with sufficient sunlight, the system will not operate normally at this time).

[0062] In some embodiments of this utility model, the pipe structure 220 includes a first pipe and a second pipe; the first pipe participates in the heat collection of the heat collection component 200, and the second pipe participates in the circulation of the circulation component 300.
