Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation materials technology, and in particular to a composite vacuum insulation board. Background Technology

[0002] Vacuum insulation panel (VIP panel) is a type of vacuum insulation material. It is composed of a core material and a vacuum protective surface layer. It effectively avoids heat transfer caused by air convection, thus significantly reducing the thermal conductivity. It does not contain any ODS material and has environmentally friendly and energy-efficient characteristics. It is currently the most advanced high-efficiency insulation material in the world.

[0003] Some refrigerator doors are equipped with vacuum insulation panels. In the prior art, the vacuum insulation panels inside the refrigerator doors are usually located close to the condenser pipes. The condenser pipes generate a lot of heat when they are working. The existing vacuum insulation panels inside the refrigerator doors cannot effectively conduct this heat, resulting in poor heat dissipation of the refrigerator doors. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a composite vacuum insulation panel, which, by setting heat dissipation fins and heat dissipation plates, can dissipate the heat generated by the pipes in a timely manner, thereby improving the heat dissipation effect of the refrigerator door.

[0005] The technical solution adopted by this application to solve its technical problem is: a composite vacuum insulation panel, including a vacuum insulation panel, a connecting plate, heat sink, pipes and heat sink;

[0006] One side of the connecting plate is connected to the vacuum insulation plate; the heat sink is connected to the other side of the connecting plate, the heat sink includes a recessed portion, and a groove is formed in the recessed portion; the pipe is disposed in the groove, and the side of the pipe is in close contact with the heat sink; the heat dissipation plate is connected to the heat sink, and the side of the heat dissipation plate is in contact with the pipe.

[0007] Furthermore, a receiving groove is formed on one side of the connecting plate, and the vacuum insulation plate is disposed in the receiving groove.

[0008] Furthermore, the connecting plate is a PU foam board.

[0009] Furthermore, a positioning groove is formed on the other side of the connecting plate, and the recessed part of the heat sink is disposed in the positioning groove.

[0010] Furthermore, the heat sink includes multiple heat dissipation fins, each heat dissipation fin including a first connecting portion, a first guiding portion, a recessed portion, a second guiding portion, and a second connecting portion. The first connecting portion is connected to one side of the first guiding portion and is fixed to a connecting plate. The other side of the first guiding portion is connected to one side of the recessed portion, the other side of the recessed portion is connected to one side of the second guiding portion, the other side of the second guiding portion is connected to the second connecting portion, and the second connecting portion is fixed to the connecting plate.

[0011] Furthermore, the heat dissipation fins, namely the first heat dissipation fin, the middle heat dissipation fin, and the last heat dissipation fin, are arranged side by side on the connecting plate, with the first heat dissipation fin protruding above the middle heat dissipation fin and protruding below the middle heat dissipation fin.

[0012] Furthermore, the heat sink is a single, continuous heat sink.

[0013] Furthermore, the heat sink is a heat-dissipating aluminum foil, and the heat sink plate is a heat-dissipating aluminum foil.

[0014] Furthermore, it also includes a connector, which includes a first connector and a second connector, the first connector being located at one end of the pipe and the second connector being located at the other end of the pipe.

[0015] Furthermore, the connector includes a nut and a locking element. The nut is fitted onto the pipe and has a connecting thread inside. One end of the locking element has an external thread that mates with the connecting thread, and the other end of the locking element has an internal thread.

[0016] The beneficial effects of this application are as follows: Since the side of the pipe is in close contact with the heat sink, the side of the heat sink is in contact with the pipe, and the heat sink and the heat sink are connected together, the pipe is located between the heat sink and the heat sink, and the pipe is in contact with both the heat sink and the heat sink. In this way, part of the heat generated by the pipe is directly dissipated through the heat sink, and the other part of the heat is conducted to the heat sink through the heat sink and then dissipated through the heat sink. This achieves timely dissipation of the heat generated by the pipe, resulting in better heat dissipation of the refrigerator door. Attached Figure Description

Detailed Implementation

[0025] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 6 As shown, a composite vacuum insulation panel of this utility model includes a vacuum insulation panel 1, a connecting plate 2, a heat sink 3, a pipe 4, and a heat sink 5; one side of the connecting plate 2 is connected to the vacuum insulation panel 1; the heat sink 3 is connected to the other side of the connecting plate 2, and the heat sink 3 includes a recessed portion 31, in which a groove is formed; the pipe 4 is disposed in the groove, and the side of the pipe 4 is in close contact with the heat sink 3; the heat sink 5 is connected to the heat sink 3, and the side of the heat sink 5 is in contact with the pipe 4.

[0027] Thus, the composite vacuum insulation plate of this utility model, because the side of the pipe 4 is closely attached to the heat sink 3, and the side of the heat sink 5 is in contact with the pipe 4, and the heat sink 5 is connected to the heat sink 3, the pipe 4 is located between the heat sink 3 and the heat sink 5, and the pipe 4 is in contact with both the heat sink 3 and the heat sink 5. In this way, part of the heat generated by the pipe 4 is directly dissipated through the heat sink 5, and the other part of the heat is conducted to the heat sink 5 through the heat sink 3, and then dissipated through the heat sink 5. This achieves timely dissipation of the heat generated by the pipe 4, making the heat dissipation effect of the refrigerator door better.

[0028] Traditionally, the side of the pipe directly contacts the heat dissipation surface material, with the pipe tangentially positioned to the surface material. However, a large area on the other side of the pipe remains uncontacted, resulting in a small contact area and poor heat dissipation. To address this, this application incorporates a heat sink 3, with a large area of ​​the other side of the pipe contacting the heat sink 3. Furthermore, the heat sink 3 is mounted on a heat dissipation plate 5, significantly increasing the contact area and effectively improving heat dissipation.

[0029] Optionally, a receiving groove 21 is formed on one side of the connecting plate 2, and the vacuum insulation board 1 is disposed in the receiving groove 21. By providing the receiving groove 21, it is easy to fix the vacuum insulation board 1 in the receiving groove 21, so that the surface of the vacuum insulation board 1 is flush with the surface of the connecting plate 2. The connecting plate 2 is preferably a PU foam board.

[0030] Furthermore, a positioning groove 22 is formed on the other side of the connecting plate 2, and the recessed portion 31 of the heat sink 3 is disposed in the positioning groove 22. By providing the positioning groove 22, the recessed portion 31 of the heat sink 3 is easily fixed in the positioning groove 22, so that the heat sink 3 is firmly connected to the connecting plate 2.

[0031] In a preferred embodiment of this utility model, the heat sink 3 includes multiple heat dissipation plates, such as... Figure 3 As shown, each heat dissipation fin includes a first connecting portion 32, a first guiding portion 33, a recessed portion 31, a second guiding portion 34, and a second connecting portion 35. The first connecting portion 32 is connected to one side of the first guiding portion 33 and is fixed to the connecting plate 2. The other side of the first guiding portion 33 is connected to one side of the recessed portion 31, and the other side of the recessed portion 31 is connected to one side of the second guiding portion 34. The other side of the second guiding portion 34 is connected to the second connecting portion 35, and the second connecting portion 35 is fixed to the connecting plate 2. The first guiding portion 33 and the second guiding portion 34 are provided with guiding arc surfaces. By providing the first guiding portion 33 and the second guiding portion 34, it is easy for the pipe 4 to be quickly placed into the recessed portion 31. By providing the first connecting portion 32 and the second connecting portion 35, it is easy for the heat dissipation fin to be fixed to the connecting plate 2.

[0032] Different types of pipes 4 have different diameters and lengths. This application can set multiple heat dissipation plates according to the type of pipe 4, so that each heat dissipation plate can make good contact with the pipe 4. At the same time, there is a gap between two adjacent heat dissipation plates. When the heat dissipation plate 5 is fixed on the connecting plate 2, the heat dissipation plate 5 can be fixed to the connecting plate 2 through the gap, so that the heat dissipation plate 5 is firmly fixed on the connecting plate 2.

[0033] Furthermore, the heat dissipation fins—first heat dissipation fin 36, middle heat dissipation fin 37, and tail heat dissipation fin 38—are arranged side-by-side on the connecting plate 2. The first heat dissipation fin 36 protrudes above the middle heat dissipation fin 37 and also protrudes below the middle heat dissipation fin 37. The first heat dissipation fin 36, middle heat dissipation fin 37, and tail heat dissipation fin 38 can be arranged in parallel to each other, thus adapting to the corresponding pipes 4.

[0034] like Figure 5As shown, in this embodiment of the present invention, the heat sink 3 is a single heat sink 39. Preferably, the heat sink 3 is a heat-dissipating aluminum foil, and the heat sink 5 is a heat-dissipating aluminum foil. The heat-dissipating aluminum foil has good thermal conductivity and can conduct the heat generated by the pipe 4 to the plate in a timely manner.

[0035] In a preferred embodiment of this invention, a connector 6 is further included. The connector 6 includes a first connector 6 and a second connector 6. The first connector 6 is disposed at one end of the pipe 4, and the second connector 6 is disposed at the other end of the pipe 4. By providing the connector 6, the connecting pipe can be directly connected to the pipe 4 through the connector 6, which is convenient to use.

[0036] Specifically, the connector 6 includes a nut 61 and a locking member 62. The nut 61 is fitted onto the pipe 4, and a connecting thread 611 is provided inside the nut 61. One end of the locking member 62 has an external thread 621 that mates with the connecting thread 611, and the other end of the locking member 62 has an internal thread 622. The end of the pipe 4 forms an outward protrusion. During use, the nut 61 is fitted onto the pipe 4, and the outward protrusion prevents the nut 61 from detaching from the pipe 4. After the locking member 62 is connected to the nut 61, the end of the locking member 62 tightly abuts against the outward protrusion, resulting in a good seal. The connecting thread 611 and the external thread 621 facilitate the secure fixing of the locking member 62 to the nut 61, while the internal thread 622 facilitates connection with a connecting pipe.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
