[0028] With reference to the drawings and specific embodiments, the technical solutions in the embodiments of the present application will be described in detail below, obviously, the described embodiments are only a 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 labor are within the scope of protection of the present application.

[0029] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0030] As shown in FIG. 1 and FIG. 2, a PVT assembly includes a solar module and a water pipe module, wherein a plurality of solar modules are spliced to form a larger PVT assembly to meet project requirements. In addition, a plurality of water pipe modules are spliced and arranged below the solar module.

[0031] The solar module includes a first shell 1 and a photovoltaic panel (not shown in the figure), wherein the first shell 1 is installed by a solar mounting rack (not shown in the figure), the photovoltaic panel is arranged on the upper surface of the first shell 1, and the solar energy is converted into electric energy by the photovoltaic panel. At the same time, the heat absorbed by the solar energy is transferred to a heat energy storage device or other utilization equipment through a heat exchanger, so as to realize the collection and utilization of light and heat energy.

[0032] As shown in FIG. 4, a plurality of water pipe modules are arranged on the lower surface of the first shell 1, wherein one solar module can place up to 5 water pipe modules, and the water pipe module includes a second shell 2 and a heat exchange pipe 3, the surface of the second shell 2 is provided with a plurality of heat exchange pipes 3, and the heat exchange pipe 3 is used for conveying heat conducting medium. At the same time of generating electricity by the photovoltaic panel, a certain amount of hot water supply can be provided for users, and the practicability is better, and it can maximize the utilization of solar energy.

[0033] In addition, the water pipe module can be detachably installed on the lower surface of the first shell 1, and whether to install the water pipe module is selected according to the use requirement. 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 adding a layer of heat preservation, and the photovoltaic panel is in a high temperature state, which affects the power generation efficiency of the photovoltaic panel. At this time, the water pipe module can be detached to enhance the overall heat dissipation effect of the PVT assembly and improve the energy utilization efficiency of the photovoltaic panel.

[0034] It needs to be explained that when the user does not need hot water supply all the time, then the water pipe module is not installed at the initial installation, effectively reducing the use cost. When the user needs to provide hot water, according to the required amount of hot water provided, the quantitative water pipe module is spliced and assembled below the solar module, flexibly adjusting the overall structure of the PVT assembly, thereby increasing the flexibility of the PVT system and improving the universality of the PVT system energy combination.

[0035] When the PVT assembly is installed, according to the needs, the orientations of the water pipe modules on the left and right sides of the first shell 1 are selected in sequence to install the second shell 2 on the bottom surface of the first shell 1. Through the modular design, the PVT assembly can be flexibly adjusted at the initial stage of the overall design. Moreover, through the modular design, the PVT assembly can be increased or decreased at any time according to the needs during the project process. When the PVT assembly is maintained and maintained later, only the single damaged solar module or water pipe module needs to be replaced, which can complete the system maintenance task faster and more efficiently, while saving maintenance cost.

[0036] As shown in Figure 3, the outer peripheral side surface of the first shell 1 is arrayed with several groups of first fixing holes 101, each group of first fixing holes 101 has two, and the outer peripheral side surface of the second shell 2 is arrayed with several groups of second fixing holes 201, each group of second fixing holes 201 has two. The first fixing hole 101 on the first shell 1 is butted with the second fixing hole 201 on the second shell 2, and preferably, they are fixedly connected together through a bolt rod, which is convenient for disassembling and installing the second shell 2 later. Of course, the second shell 2 can also be fixedly connected to the first shell 1 by riveting with rivets, and the connection mode is not limited.

[0037] The two second shells 2 adjacent to each other are fixedly connected together by a bolt rod, and the two adjacent side surfaces of the two second shells 2 are in close contact with each other, so that the two water pipe modules adjacent to each other can be butted and flush, improving the installation precision. 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, so that the heat of the photovoltaic panel can be transmitted to the water pipe module as much as possible, improving the heat transfer efficiency.

[0038] As shown in Figure 4, 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 needs.

[0039] As shown in FIG. 5 and FIG. 6, 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 respectively 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 respectively arranged at the edge positions of the side surfaces of the second shell 2, so as to distinguish the first water inlet and outlet 4 and the second water inlet and outlet 5 of the water pipe module. The user 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 multiple connection modes of the water pipe assembly are provided for the user, thereby improving the flexibility of the PVT assembly installation.

[0040] The first side surface of the first shell 1 and the second side surface of the first shell 1 are respectively provided with a first assembly slot 6 and two second assembly slots 7. 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 surface 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 surface 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 surface 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 surface of the first shell 1 are respectively connected to the second ends of the two heat exchange water pipes 3. That is, the arrangement direction of the water pipe module can be flexibly adjusted according to the user's needs, because the reserved slots on the first shell 1 are compatible in two directions, thereby further improving the flexibility of the PVT assembly installation.

[0041] 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 the user's needs. 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 use requirements of the user are met.

[0042] As shown in FIG. 7, a plurality of water pipe-free areas 202 are symmetrically arranged at the corner positions of the second shell 2. The water pipe-free area 202 is in a rectangular shape as a whole, and preferably, the projection surface of the water pipe-free area 202 is in a square shape. The side length of the square water pipe-free area 202 is between 40-50 mm, and a second fixing hole 201 is arranged at each of the two side length positions of the water pipe-free area 202. The two second fixing holes 201 on the second shell 2 located at the edge positions are both 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.

[0043] In use, the water pipe module is selected according to the requirement, the orientation of the left and right sides of the first shell 1 is selected, the first fixed hole 101 on the first shell 1 is butted against the second fixed hole 201 on the second shell 2, and the first shell 1 and the second shell 2 are fixed and connected together through a bolt rod, the second shell 2 is sequentially installed on the bottom surface of the first shell 1, and two adjacent second shells 2 are fixed and connected together through a bolt rod. Through the modular design, the PVT assembly can be flexibly adjusted in the initial stage of overall design.

[0044] To sum up, through the modular design of the PVT system, the PVT assembly can be increased or reduced at any time according to the requirement in the project process, the overall structure of the PVT system is flexibly adjusted, the use cost is effectively reduced, in the later PVT system maintenance and maintenance, the whole PVT assembly does not need to be replaced, the system maintenance task can be completed faster and more efficiently, the maintenance cost is reduced, and the maintenance efficiency is improved.
