Currently, solar water heaters cannot generate electricity while producing hot water, and solar cells cannot produce hot water while generating electricity, resulting in the underutilization of solar energy.

[0004] To solve the above-mentioned technical problems, this utility model provides a heating structure, including a transparent outer tube assembly, a transparent inner tube assembly, a water inlet pipe, and a water outlet pipe.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] like Figure 1 As shown, this utility model provides a heating structure, including a transparent outer tube assembly 1, a transparent inner tube assembly 2, a water inlet pipe 3, and a water outlet pipe 4. The outer tube assembly 1 is sleeved on the outer periphery of the inner tube assembly 2, and a partition is formed between them to provide a certain heat insulation effect, reduce heat loss, and improve thermal efficiency. The two ends of the outer tube assembly 1 and the inner tube assembly 2 are respectively sealed and connected. The water inlet pipe 3 and the water outlet pipe 4 are respectively connected to the two ends of the inner tube assembly 2 for conveying cold water to be heated into the inner tube 21 and drawing out heated hot water. The outer tube assembly 1 includes an outer tube 11 and a power generation film 12. The power generation film 12 is disposed on the inner surface of the outer tube 11 and is used to absorb the visible light portion of sunlight and convert it into electrical energy. The inner tube assembly 2 includes an inner tube 21 and a light-absorbing heating film. The light-absorbing heating film is disposed on the outer surface of the inner tube 21 and absorbs the infrared portion of sunlight and converts this energy into heat energy for heating the water flowing through the inner tube 21.

[0025] When sunlight shines on the entire structure, the visible light portion first penetrates the transparent outer tube 11 and reaches the power-generating film 12. The power-generating film 12 absorbs this light and converts it into electrical energy for power supply or other purposes. At the same time, the infrared portion of the sunlight penetrates the outer tube 11 and continues forward, where it is absorbed by the light-absorbing heating film on the inner tube 21 and converted into heat energy. This heat energy heats the water flowing through the inner tube 21, thus realizing the water heating process.

[0026] Understandably, the partition between the inner tube 21 and the outer tube 11 serves as insulation, reducing heat loss to the outside and improving the efficiency of thermal energy utilization. Since the power generation film 12 also generates heat during operation, this heat can be transferred to the inner tube 21 through the partition, further assisting in water heating and improving the overall energy conversion efficiency. This achieves full utilization of solar energy, enabling simultaneous hot water preparation and power generation within the same device, solving the problem of traditional equipment only being able to operate with a single function and thus failing to fully utilize solar energy.

[0027] Combined with appendix Figure 2 As shown, the power generation film 12 in region A absorbs sunlight transmitted through region B a second time, improving the utilization rate of sunlight. After passing through the reflector, the sunlight transmitted through region A can be reflected and absorbed a third time by the power generation film 12 in regions A and B, which can increase the light-receiving area and improve the photoelectric conversion efficiency.

[0028] Furthermore, the power-generating thin film 12 includes a first electrode layer 121, a P-type layer 122, an N-type layer 123, and a second electrode layer 124, which are sequentially deposited on the inner surface of the outer tube 11. The first electrode layer 121 serves as an electron-collecting layer, drawing out the generated current, while the second electrode layer 124 collects and draws out the current generated by the P-type layer 122 and the N-type layer 123.

[0029] When sunlight passes through the transparent outer tube 11, photons are absorbed by the P-type layer 122 and the N-type layer 123. After transitioning between the P-type and N-type layers 122 and 123, the photons move to the second electrode layer 124 and are then transmitted through an external circuit. This process creates a continuous current in the external circuit, thus converting light energy into electrical energy. In this embodiment, by placing the power-generating film 12 on the inner surface of the outer tube 11, the visible light portion of sunlight is effectively utilized for power generation, while the infrared portion is absorbed by the light-absorbing heating film on the inner tube 21 for heating. This allows for simultaneous hot water preparation and electricity production in the same device.

[0030] It should be noted that the first electrode layer 121, the P-type layer 122, the N-type layer 123 and the second electrode layer 124 are deposited on the inner surface of the outer tube 11 by chemical vapor deposition (CVD) or evaporation.

[0031] Furthermore, the surface of the power generation film 12 is provided with a plurality of connecting line groups 13 to divide the power generation film 12 into a plurality of sub-cells.

[0032] This embodiment divides the power-generating film 12 into multiple sub-cells, which better adapts to different lighting conditions. Each sub-cell can operate independently, so even if some areas are poorly lit, the sub-cells in other areas can still operate efficiently. In practical applications, the power-generating film 12 may be partially shaded. The multi-sub-cell structure can reduce the impact of local shading on overall performance because the unshaded sub-cells can still function normally.

[0033] Furthermore, the connecting line group 13 includes a first connecting line 131, a second connecting line 132, and a third connecting line 133 etched on the surface of the power generation thin film 12. The first connecting line 131 is located at least in the P-type layer 122, the N-type layer 123, and the second electrode layer 124, and the end of the first connecting line 131 away from the second electrode layer 124 is connected to the first electrode layer 121. The main function of the first connecting line 131 is to connect the first electrode layer 121, the P-type layer 122, the N-type layer 123, and the second electrode layer 124 to form a current loop.

[0034] The second connection line 132 is located between the P-type layer 122 and the N-type layer 123, and its two ends are connected to the first electrode layer 121 and the second electrode layer 124, respectively. The main function of the second connection line 132 is to effectively separate the electron-hole pairs between the P-type layer 122 and the N-type layer 123, guide electrons from the N-type layer 123 to the second electrode layer 124, and guide holes from the P-type layer 122 to the first electrode layer 121, thereby ensuring efficient transmission of electrons and holes and improving photoelectric conversion efficiency.

[0035] The third connection line 133 is located in the first electrode layer 121, and one end of the third connection line 133 is connected to the P-type layer 122. The main function of the third connection line 133 is to ensure that holes in the P-type layer 122 can be effectively transported to the first electrode layer 121. In this way, carrier losses during the transport process can be reduced, and the overall performance of the system can be improved.

[0036] In this embodiment, the first connecting line 131, the second connecting line 132, and the third connecting line 133 are drawn on the surface of the power generation film 12 by a laser scribing machine, and the first connecting line 131 and the third connecting line 133 are light-transmitting.

[0037] Furthermore, the first electrode layer 121 and the second electrode layer 124 are made of transparent conductive material. In this embodiment, by using transparent conductive material, most of the sunlight can be allowed to pass through, ensuring that photons can reach the P-type layer 122 and the N-type layer 123 for photoelectric conversion.

[0038] Furthermore, both the inner tube 21 and the outer tube 11 are made of glass to allow most of the sunlight to pass through, which is crucial for photoelectric conversion and heat absorption. In addition, glass has good heat resistance and can remain stable at high temperatures without deforming or being damaged.

[0039] Furthermore, the inner tube 21 and the outer tube 11 are longitudinally cylindrical, which allows sunlight to be irradiated more evenly on the surface of the entire tube, reducing the impact of uneven illumination, improving light utilization, and helping to improve the light energy utilization of the power generation film 12 and the light-absorbing heating film, ensuring that each part can efficiently perform photoelectric conversion and heat absorption.

[0040] Furthermore, the light-absorbing heating film is made of graphite-based materials or polyurethane foam. Graphite-based materials (such as graphite and carbon nanotubes) have very high light absorption rates, allowing them to efficiently absorb the infrared portion of sunlight and convert it into heat energy. In addition, graphite-based materials have good thermal conductivity, enabling them to quickly transfer the absorbed heat to the water in the inner tube 21, improving the water heating efficiency. Polyurethane foam, on the other hand, can have high light absorption rates, especially in the infrared spectrum, allowing it to effectively absorb the infrared portion of sunlight and convert it into heat energy.

[0041] Furthermore, the two ends of the outer tube assembly 1 and the inner tube assembly 2 are sealed together with butyl rubber and double sealant. In this embodiment, the double sealing design of butyl rubber and double sealant ensures that the two ends of the outer tube assembly 1 and the inner tube assembly 2 are completely sealed, preventing moisture from entering the system and avoiding moisture or damage to the internal components. In addition, the sealed connection also ensures the airtightness of the system, prevents gas leakage, maintains the stable operation of the system, and saves materials (EVA film and backplate encapsulation glass) without the need for lamination encapsulation process.

[0042] Furthermore, the interlayer is filled with an inert gas (such as argon, helium, krypton, etc.), which has a low thermal conductivity and can effectively reduce the transfer of heat through the gas, thus achieving a good heat insulation effect. At the same time, it protects the outer tube 11 lined with the power generation film 12 and the inner tube 21 lined with the light-absorbing heating film.

[0043] In summary, this utility model embodiment provides a heating structure in which, when sunlight shines on the entire structure, the visible light portion first penetrates the transparent outer tube 11 and reaches the power generation film 12. The power generation film 12 absorbs this light and converts it into electrical energy for power supply or other purposes. Simultaneously, the infrared portion of the sunlight penetrates the outer tube 11 and continues forward, where it is absorbed by the light-absorbing heating film on the inner tube 21 and converted into heat energy. This heat energy heats the water flowing through the inner tube 21, realizing the water heating process and achieving full utilization of solar energy. It simultaneously performs hot water preparation and power generation functions in the same device, solving the problem that traditional equipment can only operate with a single function and cannot fully utilize solar energy.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
