Description

Technical Field

[0001] This utility model relates to the field of new energy application technology, specifically to a high-efficiency photovoltaic thermal heat collection device. Background Technology

[0002] Energy issues are becoming increasingly prominent, posing a major challenge to all of humanity. Solar energy is a renewable resource that is pollution-free and has vast reserves. However, its application is not yet widespread. Currently, the most widely used, technologically mature, and economically viable application is solar water heaters.

[0003] For example, the Chinese authorized patent with announcement number CN220711408U, entitled "(Heat Collection Device for Photovoltaic Thermal Integrated Panel)," includes: a solar panel and a solar thermal component mounted on top of the solar panel. Adjustment components are provided on both sides of the solar thermal component. Each adjustment component includes an iron side plate fixed to the solar panel, a connecting plate at the bottom of the iron side plate, and two guide rods fixed at the top of the connecting plate. This invention uses the spring force to push the connecting plate upwards, thereby pushing the guide rods and maintaining a certain distance between the solar thermal component and the solar panel. The greater the distance between the solar thermal component and the solar panel, the lighter the shadow cast by the solar thermal component on the solar panel, and the smaller the impact on the solar panel. This reduces the shading of the solar panel by the solar thermal component and avoids affecting the power generation efficiency of the solar panel.

[0004] However, existing photovoltaic thermal heat collection devices suffer from limited heat conduction due to impurities in the internal water, which affects the heat transfer of the heat conveying pipes. Therefore, they do not meet current requirements. To address this, we propose a high-efficiency photovoltaic thermal heat collection device. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency photovoltaic thermal heat collection device to solve the problem mentioned in the background art that, during use, impurities in the internal water of existing photovoltaic thermal heat collection devices restrict heat conduction and affect the heat conduction of the heat conveying pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency photovoltaic thermal heat collection device, comprising: a heat collection plate body, wherein a heat conveying and conducting pipe is provided on the rear end face of the heat collection plate body, and a plurality of heat conveying and conducting pipes are provided, wherein both ends of the plurality of heat conveying and conducting pipes are connected by curved pipes.

[0007] Also includes:

[0008] An inlet end is installed at one end of the leftmost of several heat conveying pipes. The inlet end has two ends, and a first sealing plate is provided on one side of each of the two ends. There are two first sealing plates, and both first sealing plates are threaded to the ends. The inlet end has an inner cavity. Filter covers are provided on both sides of the inner cavity. There are two sets of filter covers. Filter screens are provided inside each set of filter covers. C-shaped filter covers are provided between each set of filter covers. There are two C-shaped filter covers, and both C-shaped filter covers are installed behind the position of the first sealing plate.

[0009] Preferably, the inner wall of the leftmost end of one of the plurality of heat conveying pipes is provided with a threaded inner wall, and the lower end of the inlet head is provided with a connecting end head, the connecting end head being integrally formed with the inlet head, and the connecting end head being threadedly rotatably connected to the threaded inner wall.

[0010] Preferably, each of the two ends is provided with a second sealing plate, and the second sealing plate is threadedly connected to the inlet end. The rightmost one of the plurality of conveying heat conduction pipes is provided with an outlet pipe.

[0011] Preferably, insulation clips are provided on both sides of the outer wall of the plurality of heat conveying pipes, and there are several sets of insulation clips. An embedded cavity is provided between the several sets of insulation clips, and there are several embedded cavities. The several embedded cavities respectively wrap the plurality of heat conveying pipes.

[0012] Preferably, the outer wall of several sets of the heat insulation buckle strips is provided with connecting blocks, and there are several connecting blocks. All of the several connecting blocks are fixedly connected to the outer wall of the heat insulation buckle strips, and all of the several connecting blocks are threadedly connected to the heat collection plate body by bolts.

[0013] Preferably, limit fastening posts are provided on both sides of the outside of the curved pipe, and there are several groups of limit fastening posts, the lower ends of the several groups of limit fastening posts are fixedly connected to the main body of the heat collection plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the design of the inlet end, allows external water interfaces to be connected to both ends of the inlet end. When one end fails, the other end can be connected to prevent the equipment from becoming unusable. The filter cover, filter screen, and C-shaped filter cover installed inside the inlet end can maximize the filtration of the water entering the heat transfer pipe, effectively removing impurities from the water. This maximizes the heat transfer from the heat collector plate to the water in the heat transfer pipe, preventing impurities from adsorbing onto the inner wall of the heat transfer pipe, which would restrict heat transfer and affect the heat transfer of the heat transfer pipe.

[0016] 2. By setting two ends on the inlet end, when replacing or cleaning the C-type filter cover and filter cover in one end, the C-type filter cover and filter cover in the other end can be used, thereby maximizing the convenience of using the equipment. Attached Figure Description
