Description

Technical Field

[0001] This utility model relates to the field of photovoltaic and solar thermal equipment, and in particular to a prefabricated photovoltaic and solar thermal integrated module. Background Technology

[0002] Against the backdrop of a global energy structure transition towards clean and low-carbon energy, and the continued growth in demand for building energy conservation and distributed energy, the combination of photovoltaic (PV) technology and solar thermal (Solar Thermal) technology has become an important direction for improving the comprehensive utilization efficiency of solar energy. Traditional photovoltaic modules can only convert solar energy into electrical energy, with a large amount of solar energy wasted as heat energy. Moreover, deploying photovoltaic and solar thermal systems separately would occupy twice the space, increase installation costs and construction complexity. Although early photovoltaic-thermal integrated (PVT) modules achieved synergy in "power generation + heat generation", they mostly adopted fixed, integrated rigid structures, which had problems such as cumbersome installation processes (requiring on-site pouring or complex splicing), poor adaptability (difficult to flexibly match different building roof / wall sizes and installation scenarios), and high maintenance costs (partial damage requires overall replacement). In particular, they could not meet the construction concept of "factory prefabrication and rapid on-site assembly" for prefabricated buildings and the demand for modular and lightweight components for distributed energy. Meanwhile, with the advancement of building-integrated photovoltaics (BIPV) policies and the increasing demands of users for comprehensive energy utilization efficiency, the shortcomings of traditional PVT modules in terms of space compatibility, installation efficiency, comprehensive energy efficiency, and life-cycle economics are becoming increasingly prominent. There is an urgent need for a prefabricated photovoltaic-thermal integrated module that can be prefabricated in the factory, quickly assembled on-site, and conveniently maintained, while also taking into account both power generation and heating performance, in order to solve the bottlenecks of existing technologies in terms of space occupation, installation adaptation, energy efficiency utilization, and operation and maintenance costs.

[0003] The commonly used PVT (photovoltaic-thermal integrated) modules in existing technologies employ various structures for collectors, including tube sheet, plate-fin, serpentine tube, blown aluminum, stainless steel flow channels, and other profiles. However, these structures require complex connection methods for installation, making quick connection difficult and causing inconvenience during use. Therefore, we propose a prefabricated photovoltaic-thermal integrated module. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated photovoltaic-thermal integrated module, which uses a molded flow channel buckle plate to be assembled and attached to the PVT core to form a medium flow channel. The PVT core and the molded flow channel buckle plate are manufactured independently, which ensures the process stability and quality stability of the PVT core.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A prefabricated photovoltaic-thermal integrated module includes a core panel mechanism, and a flow guiding mechanism is fixedly connected to the lower end of the core panel mechanism;

[0007] The core assembly includes a PVT core assembly. A polymer layer is formed on the inner surface of the PVT core assembly. A transparent adhesive layer is fixedly connected to the lower end of the polymer layer. A battery layer is fixedly connected to the lower end of the transparent adhesive layer. A first adhesive layer is fixedly connected to the lower end of the battery layer. An insulating layer is fixedly connected to the lower end of the first adhesive layer. A second adhesive layer is fixedly connected to the lower end of the insulating layer. A heat exchange plate is fixedly connected to the lower end of the second adhesive layer. A butt joint adhesive layer is fixedly connected to the left and right sides of the outer end of the heat exchange plate. Medium inlets are provided on both sides of the outer end of the heat exchange plate. Branch channels are provided on the outer surface of the heat exchange plate. By designing the PVT core assembly and the forming channel retainer plate to be manufactured independently, the process stability and quality stability of the PVT core assembly are ensured. Furthermore, the risk of equipment damage caused by the large thickness of the module entering the photovoltaic laminator during overall manufacturing is reduced.

[0008] Furthermore, the flow guiding mechanism includes a molded flow channel buckle plate, and the outer end surface of the molded flow channel buckle plate is provided with a second mating adhesive layer. By setting the second mating adhesive layer, the molded flow channel buckle plate can be immediately attached and connected to other components of the assembly without the need for complex mechanical operations such as drilling and screwing on site. This aligns with the concept of rapid assembly of prefabricated buildings, significantly shortens on-site construction time, and reduces labor costs and operational difficulty.

[0009] Furthermore, the molded flow channel buckle is fixedly connected to the lower end of the heat exchange plate. By setting the molded flow channel buckle to be fixedly connected to the lower end of the heat exchange plate, the molded flow channel buckle is the direct carrier of the medium flow. The fixed connection between the lower ends of the two can achieve a tight surface fit, which greatly reduces the contact thermal resistance caused by the air layer in the traditional non-fixed connection. This allows the heat absorbed by the heat exchange plate to be directly and quickly conducted to the medium in the flow channel, avoiding heat loss in the gap and significantly improving the photothermal conversion and heat exchange efficiency.

[0010] Furthermore, the first mating adhesive layer and the second mating adhesive layer are connected accordingly. By setting the first mating adhesive layer and the second mating adhesive layer to be connected accordingly, the positioning and connection of the core components can be completed by simply aligning and bonding the two adhesive layers on site. No additional calibration tools or complicated adjustment procedures are required, which improves the convenience of using the device.

[0011] Furthermore, the number of medium inlets is four, and the four medium inlets are arranged in pairs on both sides of the outer end of the heat exchange plate.

[0012] Furthermore, the molded flow channel buckle has a W-shaped structure and has two flow channels.

[0013] Furthermore, the number of the branch channels is several, and the several branch channels have a rectangular structure.

[0014] Furthermore, the first adhesive layer and the second adhesive layer are adhesive materials of the same material.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting the PVT core and the molded flow channel buckle to be manufactured independently, the overall process stability and quality stability of the PVT core are guaranteed. It also reduces the risk of equipment damage that may occur when the thick module enters the photovoltaic laminator during the overall manufacturing process. By setting the second bonding layer, the molded flow channel buckle can be attached and connected to other components of the module immediately without the need for complex mechanical operations such as drilling and screwing on site. This fits the concept of rapid splicing of prefabricated buildings, greatly shortens the on-site construction time, and reduces labor costs and operational difficulty.

[0017] 2. By setting a molded flow channel buckle plate to be fixedly connected to the lower end of the heat exchange plate, the molded flow channel buckle plate is the direct carrier of the medium flow. The fixed connection between the two at the lower end can achieve a tight surface fit, which greatly reduces the contact thermal resistance caused by the air layer in the traditional non-fixed connection. This allows the heat absorbed by the heat exchange plate to be directly and quickly conducted to the medium in the flow channel, avoiding heat loss in the gaps and significantly improving the photothermal conversion and heat exchange efficiency. By setting a corresponding connection between the first and second butt adhesive layers, the positioning and connection of the core components can be completed by simply aligning and bonding the two adhesive layers on site. No additional calibration tools or complicated adjustment procedures are required, which improves the convenience of using the device. Attached Figure Description

[0026] Reference Figure 1-5 As shown, in a preferred embodiment of this utility model, a prefabricated photovoltaic-thermal integrated module includes a core plate mechanism 1, and a flow guiding mechanism 2 is fixedly connected to the lower end of the core plate mechanism 1.

[0027] The core plate mechanism 1 includes a PVT core assembly 101. A polymer layer 102 is disposed on the inner surface of the PVT core assembly 101. A transparent adhesive layer 103 is fixedly connected to the lower end of the polymer layer 102. A battery layer 104 is fixedly connected to the lower end of the transparent adhesive layer 103. A first adhesive layer 105 is fixedly connected to the lower end of the battery layer 104. An insulating layer 106 is fixedly connected to the lower end of the first adhesive layer 105. A second adhesive layer 107 is fixedly connected to the lower end of the insulating layer 106. A heat exchange plate 108 is fixedly connected to the lower end of the second adhesive layer 107. Butt joint adhesive layers 109 are fixedly connected to the left and right sides of the outer end of the heat exchange plate 108. Mesh joints are disposed on the left and right sides of the outer end of the heat exchange plate 108. The heat exchange plate 108 has a medium inlet 110 and a branch channel 111 on its outer surface. There are four medium inlets 110, which are arranged in pairs on both sides of the outer end of the heat exchange plate 108. There are several branch channels 111, which are rectangular in structure. The first adhesive layer 105 and the second adhesive layer 107 are adhesive materials of the same material. By setting the PVT core 101 and the molding channel buckle 201 to be manufactured independently, the process stability and quality stability of the PVT core 101 are ensured, and the risk of equipment damage caused by the large thickness of the module entering the photovoltaic laminator during the overall manufacturing process is reduced.

[0028] Reference Figure 1-3As shown, the flow guiding mechanism 2 includes a forming flow channel buckle plate 201. The outer end surface of the forming flow channel buckle plate 201 is provided with a second bonding layer 202. The forming flow channel buckle plate 201 has a W-shaped structure and two flow channels. By setting the second bonding layer 202, the forming flow channel buckle plate 201 can be immediately attached and connected to other components of the assembly without the need for complex mechanical operations such as drilling and screwing on site. This fits the concept of rapid assembly of prefabricated buildings, greatly shortens on-site construction time, and reduces labor costs and operational difficulty.

[0029] Reference Figure 2-5 As shown, the molded flow channel buckle 201 is fixedly connected to the lower end of the heat exchange plate 108. By setting the molded flow channel buckle 201 to be fixedly connected to the lower end of the heat exchange plate 108, the molded flow channel buckle 201 is the direct carrier of the medium flow. The fixed connection between the lower ends of the two can achieve a tight surface fit, which greatly reduces the contact thermal resistance caused by the air layer in the traditional non-fixed connection. This allows the heat absorbed by the heat exchange plate 108 to be directly and quickly conducted to the medium in the flow channel, avoiding heat loss in the gap and significantly improving the photothermal conversion and heat exchange efficiency.

[0030] Reference Figure 2-5 As shown, the first mating adhesive layer 109 and the second mating adhesive layer 202 are connected accordingly. By setting the first mating adhesive layer 109 and the second mating adhesive layer 202 to be connected accordingly, the positioning and connection of the core components can be completed by simply aligning and bonding the two adhesive layers on site. No additional calibration tools or complicated adjustment procedures are required, which improves the convenience of using the device.

[0031] Specific implementation process: During use, align the molded flow channel buckle 201 and the second mating adhesive layer 202 with the first mating adhesive layer 109 on the outer end of the heat exchange plate 108, precisely aligning them with the second mating adhesive layer 202 on the outer end of the molded flow channel buckle 201. Directly adhere the two mating adhesive layers to complete the connection, ensuring the molded flow channel buckle 201 is tightly fixed to the lower end of the heat exchange plate 108. Connect the external medium circulation system to the four medium inlets 110 on both sides of the outer end of the heat exchange plate 108, creating a channel for subsequent heat exchange medium flow. Natural light first illuminates the entire PVT plate core. The PVT core 101, along with the inner polymer layer 102, filters stray light and optimizes light transmission efficiency, ensuring effective light penetration. The optimized light passes through the transparent adhesive layer 103 and directly reaches the underlying battery layer 104. The battery layer 104 absorbs the light energy and converts it directly into electrical energy through the photovoltaic effect, completing the power generation process. The lower end of the battery layer 104 is connected to an insulating layer 106 via a first adhesive layer 105, which isolates the battery layer 104 from the heat exchange plate 108, preventing leakage risks and ensuring power generation stability and heat generation. Initial Heat Transfer: During the absorption of light energy, the PVT core 101, polymer layer 102, and battery layer 104 simultaneously generate heat, which is transferred to the heat exchange plate 108 below. The heat exchange plate 108 acts as a heat transfer hub, rapidly accumulating heat. Because the molded flow channel plate 201 and the heat exchange plate 108 are in close planar contact, contact thermal resistance is significantly reduced. The heat from the heat exchange plate 108 is directly and rapidly transferred to the W-shaped dual flow channels of the molded flow channel plate 201, preparing for subsequent medium heating. Medium Intake and Distribution: External heat exchange media such as clean water and antifreeze... The medium enters the module through the medium inlets 110 on both sides of the heat exchange plate 108, and then flows into several branch channels 111 in the middle of the outer end of the heat exchange plate 108. The medium absorbs heat: the medium entering the branch channels 111 directly contacts the channel wall of the formed channel plate 201, and quickly absorbs the heat in the channel. The medium temperature rises, and the high-temperature medium after absorbing heat flows out of the module along the channel and is transported to heat utilization systems such as domestic hot water supply and underfloor heating. At the same time, the medium flow carries away some of the heat from the battery layer 104, avoiding overheating of the battery layer 104 and affecting photovoltaic efficiency, thus achieving synergistic optimization.
