Description

Technical Field

[0001] The present application belongs to the field of low-temperature storage equipment, and in particular, relates to a combined insulation board and an insulation device. Background Art

[0002] Thermal insulation refers to the use of artificial means to create an environment with a different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage device for food, liquids, chemicals, medicines, vaccines, scientific experiments, etc. Cold storage is a type of thermal insulation. The storage space of existing thermal insulation devices is generally a closed space composed of a warehouse roof, a warehouse wall and a warehouse bottom, and the warehouse roof, a warehouse wall and a warehouse bottom are assembled by multiple insulation boards.

[0003] Traditional insulation panels are usually composite insulation panels made by foaming PU and vacuum panels, and a connection structure is embedded in them. When splicing, one insulation panel is connected to another insulation panel to achieve fixed splicing between the two insulation panels. In order to ensure the thermal insulation performance of the vacuum panel, the connection structure needs to be spaced from the vacuum panel to prevent the connection structure from damaging the vacuum panel.

[0004] The traditional connection structure has fins for connecting the foamed PU symmetrically distributed on both sides, which will occupy the space of the vacuum panel, resulting in the vacuum panel occupying too little total volume, causing a large amount of heat to form a heat bridge from the connection structure position and conduct to the outdoors, resulting in poor insulation effect of the cold storage panel.

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] The embodiment of the present application provides a combined insulation board to solve the problem of poor insulation effect of existing cold storage boards, which will be described below with reference to the accompanying drawings.

[0035] The present application embodiment provides a combined heat insulation board. Figure 1 The combined insulation board includes a plurality of insulation boards. For the convenience of description, two adjacent insulation boards are defined as a first insulation board 11 and a second insulation board 13 .

[0036] Please combine Figure 2Any heat insulation board includes a heat insulation member 101 and a vacuum heat insulation member 103 disposed inside the heat insulation member. The heat insulation member 101 has the function of heat insulation and heat insulation, and the vacuum heat insulation member 103 also has the function of heat insulation and heat insulation. Compared with the heat insulation member 101, the vacuum heat insulation member 103 has a better heat insulation and heat insulation effect.

[0037] Among them, the material of the thermal insulation component 101 can be specifically PU (PU is the abbreviation of Polyurethane, and its Chinese name is polyurethane, which is abbreviated as polyurethane. It is a chemical substance, and its characteristic is that different physical properties such as density, elasticity, and rigidity can be obtained by simply modifying the formula). The vacuum insulation component 103 can be specifically a vacuum insulation panel. The vacuum insulation panel (also known as VIP panel) is a type of vacuum insulation material. It is composed of a filling core material and a vacuum protective surface layer. It effectively avoids heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, which can reach 0.002-0.004w / mk, which is 1 / 10 of the thermal conductivity of traditional insulation materials. The vacuum insulation panel is a type of vacuum insulation material that can effectively avoid heat transfer caused by air convection and greatly reduce the thermal conductivity. The vacuum insulation panel is mainly composed of core material, barrier film and getter, and the core material is the key factor that determines the insulation performance of the vacuum insulation panel. Common core materials include particle core material, foam core material, fiber core material and composite core material, among which fiber core material has the advantages of low density, small diameter and low thermal conductivity. The thickness of the vacuum insulation component required to achieve the same energy-saving effect is only 1 / 10-1 / 4 of that of polyurethane foam, which can effectively save space.

[0038] It is easy to understand that since the thermal conductivity of polyurethane foam is about 0.025W / (m·K) to 0.03W / (m·K), if polyurethane foam is used as the entire structure of the insulation board, then in order to achieve a better refrigeration effect, it is necessary to use thicker polyurethane foam with a larger volume, a more bloated overall structure, and a larger loss of cold. Vacuum insulation is a thermal insulation material prepared based on the principle of vacuum insulation. The vacuum degree of the core material in the packaging bag directly affects the thermal insulation performance of the vacuum insulation. However, vacuum insulation is relatively fragile and can be easily damaged or even fail when squeezed or collided.

[0039] Therefore, in order to make the insulation board have an appropriate thickness and to further improve the insulation capacity of the storage board while ensuring that the thickness remains unchanged, PU can be foamed together with the vacuum insulation board to make the insulation board of this application. PU can protect the vacuum insulation board from damage, and the vacuum insulation board can improve the insulation capacity of the insulation board.

[0040] Generally, the area of ​​a single insulation board is limited. In most scenarios, such as cold storage, it is often necessary to combine and splice multiple insulation boards to form a combined insulation board for use. Figure 1In the figure, two insulation boards are spliced ​​together. To facilitate splicing of insulation boards, a connection structure is embedded in the insulation boards. Figure 2 The first heat insulation board 11 and the second heat insulation board 13 of the embodiment of the present application are connected by a connecting structure 15. Figure 2 For the connection structure 15, only the first mounting seat 1511 and the first fin 1513 of the lock hook assembly 151, and the second mounting seat 1531 and the second fin 1533 of the lock pin assembly 153 are shown, while other structures of the connection structure 15 are not shown. For other structures of the connection structure 15, please refer to Figure 6 and Figure 7 For an introduction to other structures of the connection structure 15, please see below.

[0041] The connection structure 15 specifically includes: a lock hook assembly 151 and a lock pin assembly 153, and the lock hook assembly 151 and the lock pin assembly 153 can be hung together. The lock hook assembly 151 is installed on the first heat insulation board 11, and the lock pin assembly 153 is installed on the second heat insulation board 13. The lock hook assembly 151 and the lock pin assembly 153 are hung together, so that the first heat insulation board 11 and the second heat insulation board 13 are spliced ​​together.

[0042] Since the lock hook assembly 151 is usually made of metal material, and for reasons such as cost and processing accuracy, there may be burrs or sharp parts on the lock hook assembly 151. If the lock hook assembly 151 contacts the vacuum insulation member 103, it may cause the vacuum insulation member 103 to leak or be damaged, making the vacuum insulation member 103 ineffective. To solve this problem, in some embodiments, the lock hook assembly 151 includes a first mounting seat 1511 and a first fin 1513. The first mounting seat 1511 is at least partially located in the insulation member 101 of the first insulation board 11. The first mounting seat 1511 is installed in the insulation member 101 without causing damage to the vacuum insulation member 103. Furthermore, along the thickness direction of the vacuum insulation member, the first mounting seat 1511 is arranged opposite to the vacuum insulation member of the first insulation board 11, so that the first mounting seat 1511 can be prevented from damaging the vacuum insulation member of the first insulation board 11.

[0043] In a conventional locking hook assembly, fins are usually provided on both sides of the mounting seat. To avoid damage to the vacuum insulation component, the vacuum insulation component can only be placed between the locking hook assembly and the locking pin assembly, resulting in a small volume of the vacuum insulation component and poor insulation effect of the insulation board. In the embodiment of the present application, the first fin is located on the side of the first mounting seat away from the vacuum insulation component of the first insulation board, so that there is a large space on the side of the first mounting seat away from the first fin, and a larger volume of vacuum insulation components can be installed, so that the insulation effect of the first insulation board 11 is better.

[0044] In some embodiments, the locking pin assembly 153 includes a second mounting seat 1531 and a second fin 1533. The first mounting seat 1511 is at least partially located in the insulation component of the second insulation board 13. Along the thickness direction of the vacuum insulation component, the second mounting seat 1531 is arranged opposite to the vacuum insulation component of the second insulation board 13. The second fin 1533 is located on the side of the second mounting seat away from the vacuum insulation component of the second insulation board.

[0045] In a conventional locking pin assembly, fins are usually provided on both sides of the mounting seat. To avoid damage to the vacuum insulation component, the vacuum insulation component is placed on the side away from the extension direction of the fins, which can only reduce the volume of the vacuum insulation component or split the vacuum insulation component into multiple small plates, resulting in poor insulation effect of the insulation board. To solve this problem, in these embodiments, the second fin 1533 is located on the side of the second mounting seat away from the vacuum insulation component of the second insulation board, so that there is a larger space on the side of the second mounting seat away from the second fin, and a larger volume of vacuum insulation components can be installed, so that the insulation effect of the second insulation board is better.

[0046] In the connection structure scheme in the above-mentioned embodiment of the present application, the first fin 1513 is arranged on the side of the vacuum insulation component of the first mounting seat away from the first insulation board, and the second fin 1533 is located on the side of the vacuum insulation component of the second mounting seat away from the second insulation board. This allows the connection structure to maintain the same size of connection force while freeing up more space for the vacuum layer, so that after the warehouse panels are docked, the gap between the vacuum panels is smaller, thereby significantly reducing the thermal bridge effect caused by splicing.

[0047] Please combine Figure 2 In order to make the connection between the first heat insulation board and the second heat insulation board more stable, the extension direction of the first fin 1513 is: extending from the first mounting seat 1511 in a direction away from the first mounting seat 1511 and toward the second fin 1533. In this way, the angle between the first fin 1513 and the first mounting seat 1511 is an acute angle, and the first fin 1513 and the first mounting seat 1511 are firmly connected to the heat insulation component of the first heat insulation board. When the second insulation board pulls the first insulation board, the first fin 1513 and the first mounting seat 1511 are not easily separated from the insulation component of the first insulation board, thereby ensuring the tight connection between the first fin 1513, the first mounting seat 1511 and the insulation component of the first insulation board. The numerical range of the angle between the first fin 1513 and the first mounting seat 1511 can be between 0 degrees and 90 degrees, specifically: 30 degrees, 45 degrees, 60 degrees, 80 degrees, etc. In some specific embodiments, the angle between the first fin 1513 and the first mounting seat 1511 is 45 degrees. At this time, the connection between the first fin 1513, the first mounting seat 1511 and the insulation component of the first insulation board is more secure.

[0048] The second fin 1533 extends in a direction from the second mounting base 1531 away from the second mounting base 1531 and toward the first fin 1513 . In this way, the angle between the second fin 1533 and the second mounting seat 1531 is an acute angle, and the second fin 1533 and the second mounting seat 1531 are firmly connected to the insulation component of the second insulation board. When the first insulation board pulls the second insulation board, the second fin 1533 and the second mounting seat 1531 are not easily separated from the insulation component of the second insulation board, thereby ensuring the tight connection between the second fin 1533, the second mounting seat 1531 and the insulation component of the second insulation board. The numerical range of the angle between the second fin 1533 and the second mounting seat 1531 can be between 0 degrees and 90 degrees, specifically: 30 degrees, 45 degrees, 60 degrees, 80 degrees, etc. In some specific embodiments, the angle between the second fin 1533 and the second mounting seat 1531 is 45 degrees. At this time, the connection between the second fin 1533, the second mounting seat 1531 and the insulation component of the second insulation board is more secure.

[0049] In some embodiments, the first fin 1513 may be configured as only one first sub-fin 15131, that is, the locking hook assembly 151 may include one first sub-fin 15131, and one first sub-fin 15131 is located on the side of the vacuum insulation component of the first insulation board away from the first mounting seat, so that the locking hook assembly 151 is connected to the insulation component through the one first sub-fin 15131. In this case, the vacuum insulation component also has a large installation space, which can enhance the insulation effect of the first insulation board.

[0050] In some embodiments, the second fin 1533 may be configured as only one second sub-fin 15331, that is, the locking pin assembly 153 may include one second sub-fin 15331, and one second sub-fin 15331 is located on the side of the vacuum insulation component of the second insulation board away from the second mounting seat, so that the locking pin assembly 153 is connected to the insulation component through the one second sub-fin 15331. In this case, the vacuum insulation component also has a large installation space, which can enhance the insulation effect of the second insulation board.

[0051] Please combine Figure 2 In order to enhance the connection strength between the locking hook assembly 151 and the first heat insulation board, in some embodiments, the first fin 1513 can be configured to include a plurality of first sub-fins 15131, and the plurality of first sub-fins are fixed to the first mounting seat 1511 at intervals, so that when the locking hook assembly 151 is pulled, it is not easy to be detached from the first heat insulation board, making the first heat insulation board less likely to be damaged and more durable.

[0052] In order to enhance the connection strength between the locking pin assembly 153 and the second thermal insulation board 13, in some embodiments, the second fin 1533 can be configured to include a plurality of second sub-fins 15331, and the plurality of second sub-fins are fixed at intervals on the second mounting seat 1531, so that when the locking pin assembly 153 is pulled, it is not easy to disengage from the second thermal insulation board, making the second thermal insulation board less prone to damage and more durable.

[0053] In some specific embodiments, the lock hook assembly 151 and the lock pin assembly 153 can be configured according to actual needs. For example, only the first fin 1513 can be configured to include a plurality of first sub-fins 15131, and the plurality of first sub-fins are fixed to the first mounting seat 1511 at intervals; or, only the second fin 1533 can include a plurality of second sub-fins 15331, and the plurality of second sub-fins are fixed to the second mounting seat 1531 at intervals; or, the first fin 1513 can be configured to include a plurality of first sub-fins 15131, and the plurality of first sub-fins are fixed to the first mounting seat 1511 at intervals, and the second fin 1533 can include a plurality of second sub-fins 15331, and the plurality of second sub-fins are fixed to the second mounting seat 1531 at intervals.

[0054] Please combine Figure 2 It has been explained in the above embodiments that the first fin 1513 can be configured to include a plurality of first sub-fins 15131, and the plurality of first sub-fins are fixed to the first mounting seat 1511 at intervals. On this basis, the plurality of first sub-fins 15131 can be further configured to be installed in parallel on one side of the first mounting seat, so that the volume occupied by the plurality of first sub-fins 15131 is smaller and the force is more concentrated.

[0055] Please combine Figure 2 In the above embodiment, it has been explained that the second fin 1533 includes a plurality of second sub-fins 15331, and the plurality of second sub-fins are fixed to the second mounting seat 1531 at intervals. On this basis, the plurality of second sub-fins 15331 can be further configured to be installed in parallel on one side of the second mounting seat, so that the volume occupied by the plurality of second sub-fins 15331 is smaller and the force is more concentrated.

[0056] Please combine Figure 3 and Figure 4In the combined insulation board, the insulation board can be spliced ​​with other insulation boards. In order to facilitate the splicing between insulation boards, at least one insulation board includes a locking hook assembly 151 and a locking pin assembly 153. In this way, the insulation board can be spliced ​​with the other two insulation boards through the locking hook assembly 151 and the locking pin assembly 153. The locking hook assembly 151 and the locking pin assembly 153 in one insulation board are located at different ends of the insulation board, so that the insulation board can be spliced ​​with other insulation boards at different ends. For example, the locking hook assembly 151 is hung at one end of the insulation board, and the locking pin assembly 153 is hung at another end of the insulation board. The locking hook assembly and the locking pin assembly in one insulation board are located on the same side of the vacuum insulation component 103. In this way, the vacuum insulation component 103 can have a larger installation space, so that the insulation board has a better insulation effect.

[0057] Please combine Figure 3 and Figure 4 , Figure 4 For the connection structure 15, only the lock hook assembly 151 and the lock pin assembly 153 are specifically shown, and other specific structures of the connection structure 15 are not shown. For other specific structures of the connection structure 15, please refer to Figure 6 and Figure 7 Since the first mounting seat has the first fin 1513 mounted on only one side, in order to prevent the first fin 1513 from contacting the vacuum insulation member 103 and thus causing damage to the vacuum insulation member 103, the vacuum insulation member 103 is mounted on the side of the first mounting seat 1511 away from the first fin 1513, and the second mounting seat 1531 has the second fin 1533 mounted on only one side, in order to prevent the second fin 1533 from contacting the vacuum insulation member 103 and thus causing damage to the vacuum insulation member, the vacuum insulation member 103 is mounted on the side of the second mounting seat 1531 away from the second fin 1533.

[0058] As mentioned in the above embodiments, the lock hook assembly and the lock pin assembly in a heat insulation board are located on the same side of the vacuum insulation component. Figure 4 , Figure 5 The first mounting seat and the second mounting seat in the same insulation board are arranged to be located in the same plane, and the vacuum insulation member is parallel to and spaced from the first mounting seat. In this way, the vacuum insulation member can be designed as a plate body and can have a larger volume, thereby improving the insulation effect of the insulation board.

[0059] Please combine Figure 3 and Figure 4In any insulation board, the vacuum insulation component is embedded in the thermal insulation component, and the thermal insulation component can protect the vacuum insulation component. The insulation board can be made by foaming the vacuum insulation component and PU together, so that the foamed PU can be located around the vacuum insulation component to protect the vacuum insulation component. In addition, it can also have a certain insulation effect. In order to prevent the vacuum insulation component from contacting or being damaged by the connecting structure, specifically, in order to prevent the first fin 1513 of the locking hook assembly 151 and the second fin 1533 of the locking pin assembly 153 from contacting the vacuum insulation component and puncturing it, the first fin 1513 is installed on the thermal insulation component of the first insulation board 11, and the second fin is installed on the thermal insulation component of the second insulation board 13.

The heat insulation board includes four mutually connected side walls, and the side wall of one heat insulation board can be spliced ​​with the side wall of another heat insulation board.

In addition, the locking hook assembly 151 of the second side wall 107 of one insulation board can be hung with the locking pin assembly 153 of the first side wall 105 of another insulation board, so that the insulation board can be spliced ​​with another insulation board. In this embodiment, the two sides of an insulation board, namely the first side wall 105 and the second side wall 107, can be spliced ​​with other insulation boards.
