A thermal insulation panel assembly having a vacuum insulation structure

Abstract

This utility model proposes a thermal insulation board assembly with a vacuum insulation structure, which includes a support cover component, a vacuum wrapping component, a thermal insulation filling component, a transition positioning component, a bolted connection component, an expansion locking component, and a shielding and protective component. The thermal insulation board assembly has several wrapping bags, each of which is formed by heat-sealing the edges of two cooperating wrapping sheets, so that each wrapping bag can form an independent vacuum space. Multiple wrapping bags cooperate with each other to cover different areas of the thermal insulation board assembly, forming all-round thermal insulation protection. When a single wrapping bag leaks air, the leakage is limited to the interior of that single wrapping bag and will not affect the vacuum state of other wrapping bags. Other wrapping bags can still maintain a good vacuum environment, ensuring that the overall thermal insulation performance of the thermal insulation board assembly will not be significantly reduced due to leakage of individual bags, thus ensuring the reliability and stability of the thermal insulation board assembly during use.

Description

Technical Field

[0001] This utility model relates to thermal insulation and energy-saving materials, and more particularly to a thermal insulation board assembly with a vacuum insulation structure. Background Technology

[0002] Patent document CN202831269U discloses a composite vacuum insulation board, which includes an airtight wrapping bag and a core board. The airtight wrapping bag vacuum-seals the core board, and protective plates are provided on both surfaces of the airtight wrapping bag. By providing protective plates on both sides of the airtight wrapping bag, the outer surface of the airtight wrapping bag can be protected, reducing the possibility of the airtight wrapping bag being punctured during the installation of the composite vacuum insulation board, ensuring the reliable installation of the composite vacuum insulation board, guaranteeing its insulation performance, and improving its reliability. However, the airtight wrapping bag in this vacuum insulation board is an integral structure. If a part of it is damaged, the vacuum environment of the entire core board will fail, resulting in a significant decrease in insulation performance, and there is no possibility of repair or replacement. Therefore, it is necessary to optimize the structure of this insulation board to overcome the above-mentioned defects. Utility Model Content

[0003] The purpose of this invention is to provide a thermal insulation board assembly with a vacuum insulation structure to improve the stability of its thermal insulation state.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An insulation panel assembly with a vacuum insulation structure, comprising:

[0006] A support cover assembly having a support space;

[0007] A vacuum-wrapped component, comprising several parts, each vacuum-wrapped component being installed on a support and cover component, forming a vacuum environment inside, with the support and cover component supporting and covering the vacuum-wrapped component.

[0008] The thermal insulation filling component comprises several parts, each of which is installed in a vacuum-wrapped component and is wrapped and positioned by the vacuum-wrapped component.

[0009] A transition positioning component is installed in the carrier cover component and forms a positioning space between the transition positioning component and the carrier cover component;

[0010] A bolted connection component is installed in the support cover component and cooperates with the vacuum wrapping component and the transfer positioning component. The bolted connection component connects the support cover component, the vacuum wrapping component and the thermal insulation filling component to the wall, and the transfer positioning component connects to the support cover component.

[0011] An expanding locking member is installed in a bolted connection member. The expanding locking member radially expands the bolted connection member to lock it in place with the wall.

[0012] A shielding and protective component is installed in the positioning space between the transition positioning component and the support cover component, which can shield and protect the joint between the bolted connection component and the transition positioning component.

[0013] Specifically, the support cover components include:

[0014] The carrier substrate is cut and shaped from a calcium silicate board.

[0015] An inner coating layer, made of epoxy resin, is attached to the inner wall of the substrate and bonded to the vacuum-wrapped component.

[0016] An exterior coating, made of polyurethane coating, is attached to the outer wall of the substrate.

[0017] Vacuum-wrapped components include:

[0018] The wrapped bag body consists of several pieces, each formed by heat-sealing the edges of two matching wrapped sheets. After being wrapped around the outside of the thermal insulation filling component, a vacuum is drawn to place the thermal insulation filling component in a vacuum environment.

[0019] The wrapped sheet includes:

[0020] An outer wrapping layer is formed by cutting and covering fiberglass woven fabric;

[0021] The middle layer is made of aluminum foil and is attached to the inner wall of the outer layer.

[0022] The inner layer is made of polyethylene film and is attached to the inner wall of the middle layer.

[0023] Insulation filling components include:

[0024] The filling core consists of several parts, each filling the covering bag and formed by stacking several layers of filling sheets. Each filling sheet is made of glass fiber, and the glass fibers in adjacent filling sheets are arranged in a cross direction.

[0025] The adapter positioning components include:

[0026] The adapter end plate is a circular sheet structure cut from a spherical shell. A cylindrical positioning notch is opened on the outer wall of the support base plate. The adapter end piece is placed in the positioning notch, and a positioning space is formed between the positioning notch and the adapter end piece. A set of adapter ports are provided on the edge of the adapter end plate. Each adapter port is arranged sequentially along the circumference of the adapter end plate and penetrates both sides of the adapter end plate, so that the positioning spaces on both sides of the adapter end plate are interconnected.

[0027] Bolted connection components include:

[0028] The bolted cylindrical shell extends from between adjacent covering bags after passing through the transition end plate and the support base plate. Its inner end extends into the interior of the wall, and its outer end extends outward from the transition end plate. The inner end of the bolted cylindrical shell is also provided with an anchoring step, which protrudes radially outward from the bolted cylindrical shell and abuts against the inner wall of the wall, applying anti-detachment resistance between the bolted cylindrical shell and the wall. The bolted cylindrical shell is also provided with a collapse gap, which passes through the anchoring step, allowing the anchoring step to expand outward or collapse inward.

[0029] Bolted end cap, which is formed on the outer end of the bolted cylinder shell and fits against the outer wall of the transition end plate, and is used to axially position the bolted cylinder shell.

[0030] The diameter expansion locking component includes:

[0031] An expanding mandrel, installed in the bolted shell, allows for radial expansion of the bolted shell, causing the anchoring protrusion to expand outwards.

[0032] The shielding and protective components include:

[0033] The shielding end cap is made of sealant and fills the positioning space on both sides of the adapter end plate. The shielding end cap covers and protects the adapter end plate and the bolt end cap.

[0034] The advantages of this utility model are:

[0035] The insulation panel assembly comprises several wrapping bags, each formed by heat-sealing the edges of two mating wrapping sheets. This allows each wrapping bag to create an independent vacuum space. Multiple wrapping bags work together to cover different areas of the insulation panel assembly, providing comprehensive thermal insulation protection. The wrapping bags in different areas can provide targeted insulation based on actual heat transfer conditions. If a single wrapping bag leaks, due to its independent structure, the leakage is confined to that single bag and does not affect the vacuum state of other wrapping bags. The other wrapping bags maintain a good vacuum environment and continue to provide efficient insulation, ensuring that the overall thermal insulation performance of the insulation panel assembly does not significantly decrease due to leakage in a single bag, thus guaranteeing the reliability and stability of the insulation panel assembly during use.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0040] like Figures 1-3As shown, the insulation board assembly with a vacuum insulation structure proposed in this utility model includes a support cover component, a vacuum wrapping component, an insulation filling component, a transition positioning component, a bolted connection component, an expansion locking component, and a cover protection component. The support cover component has a support space. Several vacuum wrapping components are provided, each installed on the support cover component, creating a vacuum environment inside. The support cover component supports and covers the vacuum wrapping components. Several insulation filling components are provided, each installed in the vacuum wrapping component, where the vacuum wrapping component wraps and positions it. The transition positioning component is installed in the support cover component. A positioning space is formed between the transition positioning component and the support cover component. The bolted connection component is installed in the support cover component and cooperates with the vacuum wrapping component and the transition positioning component. The bolted connection component connects the support cover component, the vacuum wrapping component, and the thermal insulation filling component to the wall and connects the transition positioning component to the support cover component. The diameter expansion locking component is installed in the bolted connection component. The diameter expansion locking component performs a radial expansion operation on the bolted connection component to lock its connection with the wall. The cover and protective component is installed in the positioning space between the transition positioning component and the support cover component to cover and protect the joint between the bolted connection component and the transition positioning component.

[0041] In this embodiment, the carrier cover component includes a carrier substrate 110, an inner covering layer 120, and an outer covering layer 130. The carrier substrate is cut and shaped from a calcium silicate board. The inner covering layer is made of epoxy resin adhesive, which is attached to the inner wall of the carrier substrate and bonded to the vacuum wrapping component. The outer covering layer is made of polyurethane coating, which is attached to the outer wall of the carrier substrate.

[0042] The vacuum-wrapped component includes a wrapping bag, which consists of several parts. Each wrapping bag is formed by heat-sealing the edges of two wrapping sheets that cooperate with each other. After wrapping the outside of the thermal insulation filling component, a vacuum is drawn to place the thermal insulation filling component in a vacuum environment.

[0043] The wrapping sheet includes an outer wrapping layer 210, a middle wrapping layer 220, and an inner wrapping layer 230. The outer wrapping layer is formed by cutting fiberglass woven fabric, the middle wrapping layer is formed by cutting aluminum foil paper and is attached to the inner wall of the outer wrapping layer, and the inner wrapping layer is formed by cutting polyethylene film and is attached to the inner wall of the middle wrapping layer. In this embodiment, the heat-sealed connection portion at the edge of the wrapping sheet forms a sealing ring 240, which is bent to one side and extends into the inner wrapping layer.

[0044] The thermal insulation filling component includes a filling core 300, which is provided in several parts. Each filling core is filled into a covering bag and is formed by stacking several layers of filling sheets. Each filling sheet is made of glass fiber, and the glass fiber arrangement direction in adjacent filling sheets crosses each other.

[0045] The adapter positioning component includes an adapter end plate 400, which is a circular sheet structure cut from a spherical shell. A cylindrical positioning recess 111 is provided on the outer wall of the support substrate. The outer decorative layer has an opening of the same shape at the positioning recess. The adapter end plate is placed in the positioning recess, and a positioning space is formed between the positioning recess and the adapter end plate. A set of adapter through-holes 410 are provided on the edge of the adapter end plate. Each adapter through-hole is arranged sequentially along the circumference of the adapter end plate and penetrates both sides of the adapter end plate, so that the positioning spaces on both sides of the adapter end plate are interconnected.

[0046] The bolted connection component includes a bolted shell 510 and a bolted end cap 520. The bolted shell extends through the transition end plate and the support base plate, and then extends between adjacent covering bags. Its inner end extends into the wall, and its outer end extends outward from the transition end plate. The inner end of the bolted shell is also provided with an anchoring step 530, which protrudes radially outward from the bolted shell and abuts against the inner wall of the wall, applying anti-detachment resistance between the bolted shell and the wall. The bolted shell also has a collapse gap 511, which penetrates the anchoring step, allowing the anchoring step to expand outward or collapse inward. The bolted end cap is formed at the outer end of the bolted shell and fits against the outer wall of the transition end plate, providing axial positioning for the bolted shell. In this embodiment, the transition end plate has a transition slot 420, and the bolted end cap is placed in the transition slot, with its outer wall flush with the outer wall of the transition end plate. In one embodiment, the bolted shell can also penetrate through the covering bag and the filling core. Since the covering bag and the filling core are provided with multiple parts, the number of bolted shells is much less than the number of covering bags and the filling core, and has little impact on the overall thermal insulation performance of the insulation board assembly.

[0047] The expansion locking component includes an expansion core rod 600, which is installed in the bolted shell and can perform radial expansion operation on the bolted shell, so that the anchoring protrusion is in an outward expansion state.

[0048] The shielding and protective component includes a shielding end cap 700, which is made of caulking compound and fills the positioning spaces on both sides of the adapter end plate. The shielding end cap shields and protects the adapter end plate and the bolted end cap. In this embodiment, the outer wall of the bolted end cap is also provided with positioning protrusions 521. The shielding end cap engages with the positioning protrusions, which assist in positioning the bolted end cap.
