Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a novel phase change energy storage plate. Background Technology

[0002] Phase change energy storage building materials consist of phase change substances and a building substrate, possessing excellent energy storage and release capabilities; compared to ordinary building insulation materials, they have higher heat capacity and thermal inertia. When the microenvironment temperature of the phase change substance is below its phase change point, the substance condenses from a liquid to a solid state, releasing heat; when the microenvironment temperature is above its phase change point, the substance melts from a solid to a liquid state, absorbing heat. Through this energy storage and release, the goal of maintaining room temperature and achieving energy conservation and emission reduction is achieved.

[0003] For example, a phase change energy storage composite heating wall panel disclosed in Chinese utility model patent (authorization announcement number: CN206840852U) includes a base plate, an insulation plate, a phase change energy storage plate, and a surface decorative plate arranged sequentially from bottom to top. The upper and lower ends of the insulation plate are sealed and bonded to the base plate and the phase change energy storage plate, respectively, and the upper end of the phase change energy storage plate is sealed and bonded to the surface decorative plate. The phase change energy storage plate includes a lower plate, a high thermal conductivity upper plate, and a metal honeycomb core layer plate sandwiched between the lower plate and the upper plate. The lower plate, the upper plate, and the honeycomb core layer plate are sealed and bonded together, forming a plurality of independent and sealed phase change units within the honeycomb core layer plate. Each phase change unit is wholly or partially filled with phase change energy storage material.

[0004] However, the phase change energy storage composite heating wall panel disclosed in the above-mentioned prior art has two defects: First, the wall panel is arranged from bottom to top as a base plate, an insulation plate, a phase change energy storage plate, and a surface decorative plate. The phase change energy storage plate includes a lower plate, an upper plate, and a metal honeycomb core layer sandwiched between the lower plate and the upper plate. The composite heating wall panel has a large number of plate layers, which makes the process complicated and increases the production cost. Second, the lower plate, the upper plate, and the honeycomb core layer are sealed and bonded together. When the phase change material undergoes a solid-liquid phase change, leakage is likely to occur, which will then escape from the matrix material and pollute the surrounding air environment.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a new type of phase change energy storage plate, which adds a frame around the grid and seals the frame with the base plate and the panel, effectively preventing leakage of the phase change thermal storage material during the solid-liquid phase change process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A novel phase change energy storage plate includes a base plate, a support frame, and a panel arranged sequentially from bottom to top. The support frame includes a grid and a frame surrounding the grid. The lower end of the support frame is sealed and bonded to the base plate, and the upper end is sealed and bonded to the panel to form several independent cavities. At least a portion of the cavities are filled with phase change thermal storage material.

[0009] Furthermore, the wall thickness of the frame is greater than the wall thickness of the grille.

[0010] Furthermore, the frame is made of aluminum, plastic, or stone-plastic composite material.

[0011] Furthermore, the cross-section of the cavity is polygonal.

[0012] Furthermore, the phase change temperature of the phase change thermal storage material is 5℃~35℃.

[0013] Furthermore, the base plate, grille, and panel are made of aluminum, stainless steel, copper, plastic, or stone-plastic composite materials.

[0014] Furthermore, the thickness of both the base plate and the panel is 0.1mm to 3mm.

[0015] Furthermore, the thickness of the supporting frame is 3mm to 30mm.

[0016] Furthermore, the wall thickness of the frame is greater than 3mm.

[0017] Furthermore, the left and right sides of the support frame are respectively provided with protrusions and grooves, and the shape of the protrusions matches the shape of the grooves.

[0018] The beneficial effects of this utility model after adopting the above structure are as follows:

[0036] Example 1

[0037] like Figures 1 to 3 As shown, a novel phase change energy storage plate includes a base plate 1, a supporting frame 2, and a panel 3 arranged sequentially from bottom to top. The supporting frame 2 includes a grid 21 and a frame 22 disposed around the grid. The lower end of the supporting frame 2 is sealed and bonded to the base plate 1, and the upper end is sealed and bonded to the panel 3 to form several independent cavities. At least a portion of the cavities are filled with phase change thermal storage material 4. The thickness of the base plate 1 and the panel 3 is 0.1 mm to 3 mm, and the thickness of the supporting frame 2 is 3 mm to 30 mm.

[0038] Based on the above embodiments, this utility model provides a novel phase change energy storage plate, comprising a base plate 1, a supporting frame 2, and a panel 3 arranged sequentially from bottom to top. The supporting frame 2 includes a grid 21 and a frame 22 disposed around the grid. The lower end of the supporting frame 2 is sealed and bonded to the base plate 1, and the upper end is sealed and bonded to the panel 3 to form several independent cavities. At least a portion of the cavities are filled with phase change thermal storage material 4. This utility model simplifies the production process, reduces production costs, and improves production efficiency by reducing the number of plate layers. Simultaneously, the addition of a frame 22 around the grid 21, with the frame 22 sealed to the base plate 1 and the panel 3, effectively prevents leakage of the phase change thermal storage material 4 during the solid-liquid phase change process.

[0039] In this embodiment, the support frame 2 includes a grid 21 and a frame 22 arranged around the grid. The support frame 2, together with the base plate 1 and the panel 3, forms several independent cavities. At least a portion of the cavities are filled with phase change thermal storage material 4. That is, the phase change thermal storage material 4 is divided into numerous smaller phase change units in the support frame 2 through the grid 21 structure. These phase change units are actually numerous independent small heat sinks. Each heat sink can quickly transfer phase change heat to the panel 3 and exchange heat with the environment through the panel 3. Together, they accelerate the heat absorption and release rate of the phase change thermal storage material 4, effectively improving the phase change rate and heat utilization rate of the phase change thermal storage material 4. This slows down the fluctuation of indoor temperature, prolongs the time of maintaining a comfortable indoor temperature, reduces the number of times the air conditioning or heating system runs, and achieves the purpose of automatically regulating indoor temperature and reducing energy consumption.

[0040] In this embodiment, when installing the energy storage panel, the base plate 1 is attached to the wall, and the panel 3 faces the interior to facilitate heat exchange between the energy storage panel and the interior environment. In a further preferred embodiment, a decorative film (not shown in the figure) is also provided on the upper surface of the panel 3 to enhance the aesthetics of the energy storage panel.

[0041] As another preferred embodiment of this utility model, the frame 22 is made of aluminum, plastic, or stone-plastic composite material. The wall thickness of the frame 22 is greater than the wall thickness of the grille 21. The wall thickness of the frame 22 is greater than 3mm. In this embodiment, the frame 22 is made of plastic. Because plastic has a low density, much lower than metal, it can reduce the weight of the frame 22, thereby reducing the overall weight of the energy storage panel. Furthermore, plastic has a simple processing technology, low production cost, and strong chemical stability. The frame 22 is made of aluminum, which balances high strength and lightweight. A dense aluminum oxide protective film easily forms on the aluminum surface, making it less prone to corrosion and reducing maintenance costs. The frame 22 is made of stone-plastic composite material. Stone-plastic composite material integrates the advantages of stone and plastic through composite technology, achieving a balance in performance, environmental protection, and economy, making it particularly suitable for the multi-functional and low-maintenance needs of modern building decoration. In this embodiment, the wall thickness of the frame 22 is greater than the wall thickness of the grille 21. Figure 3 As shown, the wall thickness of the frame 22 is W1, and the wall thickness of the grille 21 is W2, where W1 > W2. The thinner wall thickness of the grille 21 reduces its weight and increases its thermal conductivity. Conversely, the thicker wall thickness of the frame 22 (greater than 3mm) provides better rigid support for the grille 21, extending its service life. Furthermore, during production, the frame 22 is sealed to the base plate 1 and the panel 3, effectively preventing leakage of the phase change thermal storage material 4 during the solid-liquid phase change process.

[0042] In another preferred embodiment of this utility model, the cross-section of the cavity is polygonal. In this embodiment, the cross-section of the cavity is polygonal, specifically it can be triangular, quadrilateral, pentagonal, or hexagonal, but is not limited to these. This structural design utilizes the close-packing, mechanical stability, and ease of processing of polygons to improve energy storage efficiency and the practicality of the sheet material. In a further preferred embodiment, such as... Figure 3 As shown, the cross-section of the cavity is quadrilateral, specifically rectangular. The rectangular cavity structure helps to reduce processing costs and allows for flexible adjustment of the length-to-width ratio of the energy storage plate to adapt to standardized installation on building walls.

[0043] As another preferred embodiment of this utility model, the phase change thermal storage material 4 has a phase change temperature of 5℃ to 35℃. In this embodiment, the phase change temperature setting of 5℃ to 35℃ combines environmental adaptability and energy efficiency, covering the human comfort zone and the daily ambient temperature fluctuation range, making the energy storage panel an ideal temperature control solution in fields such as construction.

[0044] As another preferred embodiment of this utility model, the base plate 1, the grille 21, and the panel 3 are made of aluminum, stainless steel, copper, plastic, or stone-plastic composite materials. In this embodiment, aluminum, stainless steel, copper, plastic, or stone-plastic composite materials have excellent impermeability, which can effectively prevent the penetration and migration of phase change substances during long-term use, ensuring the safety of indoor air quality.

[0045] Example 2

[0046] This embodiment provides a novel phase change energy storage plate, whose main structure and related principles are the same as those in Embodiment 1, except that:

[0047] The left and right sides of the support frame 2 are respectively provided with protrusions 23 and grooves 24, and the shape of the protrusions 23 matches the shape of the grooves 24.

[0048] In this embodiment, as Figure 4 and Figure 5As shown, adjacent energy storage panels are quickly positioned and reliably spliced ​​through protrusions 23 and grooves 24, avoiding any height difference between adjacent panels after splicing. Specifically, both protrusions 23 and grooves 24 are provided on the frame 22. In a further embodiment, the base plate 1 is provided with a first notch 11, and the panel 3 is provided with a second notch 31. When the first notch 11 is located on the left side of the first base plate 1, the second notch 31 is located on the right side of the panel 3; when the first notch 11 is located on the right side of the first base plate 1, the second notch 31 is located on the left side of the panel 3. This achieves a staggered fit between the base plate 1 and the panel 3. When adjacent energy storage panels are spliced ​​through protrusions 23 and grooves 24, the panel 3 and the base plate 1 provide support at the splicing point to improve the strength of the splicing point.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
