[0002] Photovoltaic-thermal (PVT) technology refers to a combined photovoltaic (PV) and solar thermal power generation technology, which integrates PV power generation with solar thermal utilization. PVT achieves dual energy utilization by simultaneously utilizing both solar thermal and photovoltaic effects, further improving the overall efficiency of the PV system. In PVT technology, PV modules not only generate electricity but also transfer heat to thermal energy storage devices or other utilization equipment via heat exchangers behind the modules, achieving the collection and utilization of solar and thermal energy. In this way, PVT systems can simultaneously generate electricity and heat, improving overall energy efficiency.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0028] In order to make those skilled in the art better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] As Figure 1 and Figure 2 ​As shown, a PVT module includes solar modules and water pipe modules. Multiple solar modules are spliced ​​together to form a larger PVT module to meet project requirements. Additionally, multiple water pipe modules are spliced ​​and positioned below the solar modules.

[0030] The solar module includes a first housing 1 and a photovoltaic panel (not shown in the figure). The first housing 1 is mounted using a solar mounting bracket (not shown in the figure), and the photovoltaic panel is disposed on the upper surface of the first housing 1, converting solar energy into electrical energy. Simultaneously, the heat absorbed by the solar energy is transferred to a thermal energy storage device or other utilization equipment through a heat exchanger, thereby realizing the collection and utilization of solar thermal energy.

[0031] like Figure 4 As shown, several water pipe modules are arrayed on the lower surface of the first housing 1. Each solar module can hold up to 5 water pipe modules. The water pipe module includes a second housing 2 and a hot water exchange pipe 3. Several hot water exchange pipes 3 are arranged on the surface of the second housing 2. The hot water exchange pipes 3 are used to transport heat transfer medium. While the photovoltaic power generation panel generates electricity, it can provide users with a certain amount of hot water supply, which is more practical and can maximize the utilization of solar energy.

[0032] In addition, the water pipe module can be detachably installed on the lower surface of the first housing 1. Depending on the usage requirements, it is optional to install the water pipe module. It should be noted that when the user does not need to provide hot water, the water pipe module installed below the solar module is equivalent to an extra layer of insulation. The photovoltaic panel is in a high-temperature state, which will affect the power generation efficiency of the photovoltaic panel. At this time, the water pipe module can be removed to enhance the overall heat dissipation effect of the PVT module and improve the energy utilization efficiency of the photovoltaic panel.

[0033] It should be noted that if the user does not require hot water supply, the water pipe module will not be installed initially, effectively reducing operating costs. When the user needs hot water, a fixed amount of water pipe modules are assembled below the solar module according to the required hot water volume. This allows for flexible adjustment of the overall structure of the PVT module, thereby increasing the flexibility of the PVT system and improving the versatility of its energy combinations.

[0034] During PVT module installation, the second housing 2 is installed on the bottom surface of the first housing 1, following the orientation of the left and right sides of the water pipe module on the first housing 1 as required. This modular design allows for flexible adjustments to the PVT modules from the initial design stage. Furthermore, the modular design allows for the addition or removal of PVT modules as needed during the project. Later maintenance and repairs only require replacing individual damaged solar or water pipe modules, enabling faster and more efficient system maintenance while saving on repair costs.

[0035] As Figure 3 shown, the outer peripheral side surface of the first shell 1 is arranged with a plurality of groups of first fixing holes 101, each group of first fixing holes 101 is provided with two, the outer peripheral side surface of the second shell 2 is arranged with a plurality of groups of second fixing holes 201, each group of second fixing holes 201 is provided with two, the first fixing hole 101 on the first shell 1 is butted against the second fixing hole 201 on the second shell 2, preferably, fixedly connected together through a bolt rod, facilitating disassembly and installation of the second shell 2 in the later period. Of course, riveting can also be selected to fix and connect the second shell 2 to the first shell 1, and the connection mode is not limited.

[0036] Two second shells 2 adjacent to each other are fixedly connected together through a bolt rod, and the two adjacent side surfaces of the two second shells 2 are in close contact with each other, ensuring that the two water pipe modules adjacent to each other can be butted flush, improving the installation accuracy. The inner peripheral side surface of the first shell 1 is in close contact with the outer peripheral side surface of the second shell 2, and the bottom surface of the first shell 1 is in close contact with the top surface of the second shell 2, ensuring that the heat of the photovoltaic power generation panel can be transmitted to the water pipe module as much as possible, improving the heat transfer efficiency.

[0037] As Figure 4 shown, specifically, two heat exchange water pipes 3 are symmetrically arranged on the surface of the second shell 2, and the two heat exchange water pipes 3 are not connected to each other. The two heat exchange water pipes 3 in the same water pipe module can simultaneously transport two different heat conducting media, providing different temperature requirements for subsequent projects. Of course, the same heat conducting medium can also be transported according to the requirements.

[0038] As Figure 5 and Figure 6 shown, the first end of the heat exchange water pipe 3 is provided with a first water inlet and outlet 4, and the second end of the heat exchange water pipe 3 is provided with a second water inlet and outlet 5. The first water inlet and outlet 4 and the second water inlet and outlet 5 are arranged on the two sides of the second shell 2. In the same water pipe module, the first ends of the two heat exchange water pipes 3 are arranged at the middle positions of the side surfaces of the second shell 2, and the second ends of the two heat exchange water pipes 3 are arranged at the edge positions of the side surfaces of the second shell 2, respectively, for distinguishing the first water inlet and outlet 4 and the second water inlet and outlet 5 of the water pipe module. Users can determine the orientation of the water pipe assembly according to the positions of the first water inlet and outlet 4 and the second water inlet and outlet 5, and provide users with a variety of connection modes of the water pipe assembly, improving the flexibility of the PVT assembly installation.

[0039] The first side of the first shell 1 and the second side of the first shell 1 are provided with a first assembly slot 6 and two second assembly slots 7, wherein the two second assembly slots 7 are symmetrically arranged on the two sides of the first assembly slot 6, and the two second assembly slots 7 are arranged between the two first fixing holes 101. When the first assembly slot 6 located on the first side of the first shell 1 is connected to the first ends of the two heat exchange water pipes 3, the two second assembly slots 7 located on the second side of the first shell 1 are respectively connected to the second ends of the two heat exchange water pipes 3. When the first assembly slot 6 located on the second side of the first shell 1 is connected to the first ends of the two heat exchange water pipes 3, the two second assembly slots 7 located on the first side of the first shell 1 are respectively connected to the second ends of the two heat exchange water pipes 3. That is, the placement direction of the water pipe module can be flexibly adjusted according to user needs, because the reserved slot on the first shell 1 is compatible in two directions, thereby further improving the flexibility of the PVT assembly installation.

[0040] It should be noted that the first water inlet and outlet 4 and the second water inlet and outlet 5 of different water pipe modules and the same water pipe module can be connected together by a hose according to user needs, and when the first water inlet and outlet 4 and the second water inlet and outlet 5 in multiple water pipe modules are connected in series, different user needs are met.

[0041] As shown in Figure 7 The corner position of the second shell 2 is symmetrically provided with a plurality of waterless pipe areas 202, and the overall projection of the waterless pipe area 202 is in a rectangular shape, preferably, the overall projection of the waterless pipe area 202 is in a square shape, and the side length of the square waterless pipe area 202 is between 40-50mm, and a second fixing hole 201 is arranged at the position of two side lengths of the waterless pipe area 202. The two second fixing holes 201 on the second shell 2 located at the edge position are used to connect the first fixing hole 101 on the first shell 1. One of the second fixing holes 201 on the second shell 2 located at the middle position is used to connect the first fixing hole 101 on the first shell 1, and the other second fixing hole 201 is used to connect the second fixing hole 201 on the adjacent second shell 2.

[0042] When the application is used, according to the needs, the orientation of the left and right sides of the water pipe module on the first shell 1 is selected, the first fixing hole 101 on the first shell 1 is connected to the second fixing hole 201 on the second shell 2, and the second shell 2 is fixed and connected together through the bolt rod. By modular design, the PVT assembly can be flexibly adjusted in the initial design of the overall design.

[0043] In conclusion, the application can effectively reduce the use cost by modularizing the design of the PVT system, increasing or reducing the PVT components according to the requirements in the project process, flexibly adjusting the overall structure of the PVT system, and without replacing all the PVT components in the later PVT system maintenance and maintenance, the system maintenance task can be completed faster and more efficiently, the maintenance cost is reduced, and the maintenance efficiency is improved.
