Description

Technical Field

[0001] This utility model relates to a vacuum insulation panel, specifically a vacuum insulation panel with a replaceable core, belonging to the field of vacuum insulation panel technology. Background Technology

[0002] Vacuum insulation panels (VIP panels) are a new type of high-efficiency thermal insulation material, mainly composed of a core material, a barrier membrane, and a getter. The core material is the key factor determining the insulation performance of the vacuum insulation panel. Common core materials include granular core materials, foam core materials, fiber core materials, and composite core materials. Among them, fiber core materials have advantages such as low density, small diameter, and low thermal conductivity. Vacuum insulation panels create a vacuum environment by removing internal air, effectively avoiding heat transfer caused by air convection, thus significantly reducing the thermal conductivity. This design can achieve a thermal conductivity of 0.002-0.004 W / mK, which is 1 / 10 of the thermal conductivity of traditional insulation materials. Vacuum insulation panels are widely used in thermal insulation fields, such as household refrigerators, yacht refrigerators, mini-fridges, vehicle refrigerators, deep freezers, electric water heaters, vending machines, freezers, refrigerated containers, building wall insulation, and LNG storage and transportation.

[0003] Currently, most existing vacuum insulation panels require tools such as screwdrivers and wrenches to replace the core. Using these tools to remove the old core may require unscrewing some fixing screws, which can limit the range and efficiency of disassembly. To address these issues, we provide a vacuum insulation panel with a replaceable core. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a vacuum insulation panel with a replaceable core, the specific technical solution of which is as follows:

[0005] A vacuum insulation panel with replaceable core includes a first support frame, a second support frame, and a core body. A support column is provided at the top of the first support frame, and a rotating plate is rotatably provided at the top of the support column. An installation hole is provided at the top of the rotating plate, and a spring is provided inside the installation hole. A positioning frame is provided at the top of the spring, and the positioning frame movably passes through the bottom end of the rotating plate.

[0006] Preferably, the top of the first support frame is provided with a joint groove, and the joint groove is rectangular in shape. The bottom of the second support frame is provided with a joint frame, and the joint frame is inserted into the joint groove.

[0007] Preferably, the interior of the second support frame has four through slots, and the rotating plate can be movably inserted into the through slots.

[0008] Preferably, the second support frame has a slot inside, and the slot is a circular hole that communicates with the inside of the through groove. A column cover cap is movably installed inside the slot.

[0009] Preferably, the slot has two sets of positioning holes inside, and the positioning frame is movably inserted into the positioning holes.

[0010] Preferably, the core body is disposed inside the first support frame and the second support frame. The core body is made of fiber core material. The outer side of the first support frame and the second support frame is provided with a packaging layer, and the packaging layer is made of a material with low air permeability and high strength, such as polyimide film.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

In this utility model, by setting up components such as a rotating plate and a positioning frame, during the assembly of the second support frame and the first support frame, the rotating plate is inserted into the through groove, and the rotating plate is rotated 90 degrees inside the positioning groove, so that the positioning frame that moves through the rotating plate is inserted into the positioning hole, thereby realizing the assembly and positioning of the first support frame and the second support frame. During the replacement of the core body of the vacuum insulation panel, it is only necessary to pull the positioning frame out of the positioning hole and adjust the rotating plate inside the positioning groove to adapt to the through groove. Without the need to use external tools to remove the screws, the first support frame and the second support frame can be disassembled and the core body replaced, effectively improving the disassembly efficiency of the vacuum insulation panel.

[0013] 2. In this utility model, by providing components such as a joint frame and a joint groove, the joint frame can be inserted into the interior of the joint groove during the assembly of the first support frame and the second support frame, thereby increasing the stability of the assembly of the first support frame and the second support frame.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A type of vacuum insulation panel with replaceable core;

[0023] The system includes a first support frame 1, a second support frame 3, and a core body 14. The first support frame 1 has a support column 9 at its top, and a rotating plate 10 is rotatably mounted on the top of the support column 9. The top of the rotating plate 10 has a mounting hole 11, and a spring 12 is installed inside the mounting hole 11. A positioning frame 13 is installed on the top of the spring 12 and moves through the bottom end of the rotating plate 10. The second support frame 3 has four through slots 5 inside, and the rotating plate 10 can be movably inserted into the through slots 5. The second support frame 3 has a locking slot 6 inside, and the locking slot 6 is a round hole that communicates with the inside of the through slots 5. A column cover cap 7 is movably mounted inside the locking slot 6, and two positioning holes 8 are opened inside the locking slot 6. The positioning frame 13 is movably inserted into the positioning holes 8.

[0024] The through groove 5 inside the second support frame 3 has the same shape as the rotating plate 10, but the size of the through groove 5 is larger than that of the rotating plate 10. The through groove 5 is connected to the inside of the locking groove 6. After the core body 14 is assembled inside the first support frame 1, during the assembly of the second support frame 3 and the first support frame 1, the rotating plate 10 is adjusted to the same angle as the through groove 5 and inserted into the through groove 5 until the rotating plate 10 passes through the through groove 5 and is located in the circular locking groove 6. The length of the support column 9 is equal to the locking height inside the through groove 5. At this time, the support column 9 is located in the through groove 5 and is rotatably connected to the top of the support column 9 by the rotating plate 10. The rotating plate 10 rotates 90 degrees inside the slot 6, causing the positioning frame 13, which moves through the rotating plate 10, to insert into the positioning hole 8. The spring 12 inside the mounting hole 11 is used to elastically stretch the positioning frame 13, so that the positioning frame 13 is elastically stretched and inserted into the positioning hole 8, thereby realizing the assembly and positioning of the first support frame 1 and the second support frame 3. During the replacement of the core body 14 of the vacuum insulation panel, it is only necessary to pull the positioning frame 13 out of the positioning hole 8 and adjust the rotating plate 10 inside the slot 6 to adapt to the angle of the through groove 5. The core body 14 can be replaced without the need to use external tools to remove the screws, which effectively improves the disassembly efficiency of the vacuum insulation panel.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A type of vacuum insulation panel with replaceable core;

[0026] The top of the first support frame 1 is provided with a joint groove 2, which is rectangular in shape.

The outer side of the first support frame 1 and the second support frame 3 is provided with a packaging layer 15, which is made of a material with low air permeability and high strength, such as polyimide film.

[0027] Support frame 1 and support frame 3 are the main internal support frame structures of the vacuum insulation panel. Both support frame 1 and support frame 3 are made of plastic. Support frame 1 and support frame 3 can be used to limit the installation of the core body 14. During the assembly of support frame 1 and support frame 3, the connecting frame 4 can be inserted into the connecting groove 2 to increase the stability of the assembly of support frame 1 and support frame 3. Support frame 1 and support frame 3 can limit the outer side of the core body 14, which can effectively increase the overall strength of the vacuum insulation panel.
