Description

BACKGROUND

[0001] (a) TECHNICAL FIELD

[0002] The present disclosure relates to a vacuum thermal insulator capable of being manufactured in a desired component shape to manufacture a vehicle component, a method of manufacturing a vehicle component using the vacuum thermal insulator, and a roof structure including the vehicle component.

[0003] (b) BACKGROUND

[0004] In order to improve fuel efficiency and increase the driving range while driving a vehicle, it is necessary to minimize energy unnecessarily wasted or lost in the vehicle. In particular, for an electric vehicle without an internal combustion engine (ICE), it is considered very important to effectively use electric energy to increase the driving range from the viewpoint of marketability and availability of the vehicle.

[0005] An electric vehicle uses electric energy stored in a battery to perform driving or air conditioning. In addition, during charging of the battery using a fast charging device, the vehicle must be stopped, and it takes a longer time to charge the battery than to refuel a general internal combustion engine vehicle.

[0006] Therefore, it is essential to increase the driving range of an electric vehicle by effectively using energy during operation of the vehicle. In particular, since the proportion of energy consumed for cooling and heating is high in an electric vehicle, it is necessary to improve thermal efficiency through indoor thermal management.

[0007] To this end, it is possible to consider applying a thermal insulation material to a vehicle component. For example, a component shaped in the form of a felt or a plate can be used for a roof (i.e., a ceiling) structure. By attaching a component shaped of such a material to the roof, not only can noise from the outside of the vehicle be blocked from entering the inside, but also thermal insulation between the inside and the outside of the vehicle can be improved.

[0008] Although a conventional roof component material can be said to have good sound absorption or sound insulation performance with respect to noise from the outside of the vehicle, there is a problem in that the thermal insulation effect with respect to heat introduced from the outside of the vehicle or heat escaping from the vehicle is small. SUMMARY

[0009] Therefore, the present disclosure is made in consideration of the problems encountered in the related art, and an object of the present disclosure is to provide a vacuum thermal insulator for a vehicle, which has excellent sound insulation and thermal insulation performance and is easy to process and shape into a component shape.

[0013] Further, the outer shell material can be a metal composite film in which any one metal selected from aluminum, gold, silver, copper, nickel, cobalt, chromium, and tin is stacked on a surface of a film material.

[0014] Further, the support and the outer shell material can be spaced apart from each other by the insulation body interposed therebetween so as not to contact each other.

[0016] Further, the vehicle component can be a roof duct attached to a roof liner and configured to receive heating air for indoor heating or cooling air for indoor cooling from an air conditioning device and guide the air to a roof vent to discharge inwardly.

[0017] It can be provided as a roof duct attached to a roof liner and configured to receive heating air for indoor heating or cooling air for indoor cooling from an air conditioning device and guide the air to a roof vent to discharge inwardly.

[0018] Another embodiment of the disclosure provides a method of manufacturing a vehicle component, including manufacturing a perforated plate in which a plurality of holes are formed by perforating a metal plate, shaping the perforated plate into a predetermined shape according to a shape of the component, applying an adhesive to a predetermined portion including an edge portion of the perforated plate, stacking an insulation body on each of both sides of the perforated plate, and stacking an outer shell material on an outer surface of the stacked insulation body, and performing a vacuum compression process of applying a vacuum pressure between the outer shell materials of both sides and applying heat and pressure to the outer shell material, wherein a support made of the perforated plate can be disposed in the insulation body, and the outer shell material can be configured to surround the insulation body and to be joined to an outer surface of the insulation body in a vacuum compression state to seal and maintain an internal space in which the insulation body and the support are accommodated in a vacuum.

[0019] In some embodiments, the metal plate can be an aluminum alloy plate or a stainless steel plate.

[0020] Further, the outer shell material can be a metal composite film in which any one metal selected from the group consisting of aluminum, gold, silver, copper, nickel, cobalt, chromium, and tin is stacked on a surface of a film material.

[0021] Further, the support and the outer shell material after vacuum compression can be spaced apart from each other by a thermal insulator interposed therebetween, when the vacuum compression process is performed.

[0022] Further, the vehicle component can be a roof duct attached to a roof liner and configured to receive heating air for indoor heating or cooling air for indoor cooling from an air conditioning device and guide the air to a roof vent to discharge inwardly.

[0035] Hereinafter, a detailed description will be given of embodiments of the disclosure with reference to the accompanying drawings. The detailed description of specific structures and functions of the embodiments of the disclosure is merely illustrative for the purpose of explaining embodiments according to the concept of the disclosure, and the embodiments of the disclosure can be implemented in various forms. In addition, the disclosure should not be construed as being limited to the embodiments described in the present specification, but should be understood to include all changes, equivalents, and substitutions included in the spirit and technical scope of the disclosure.

[0036] Meanwhile, it should be understood that although the terms such as "first", "second", etc. can be used herein to describe various elements, the elements are not limited by these terms. These terms are used only to distinguish one element from another element. For example, the "first" element discussed below can be referred to as the "second" element without departing from the scope of the disclosure. Similarly, the "second" element can also be referred to as the "first" element.

[0037] It should be understood that when an element is referred to as being "coupled" or "connected" to another element, it can be directly coupled or connected to the other element, or there can be an intermediate element therebetween. In contrast, it should be understood that when an element is referred to as being "directly coupled" or "directly connected" to another element, there is no intermediate element. Other expressions explaining the relationship between elements, such as "between", "directly between", "adjacent to", or "directly adjacent to", should be interpreted in the same way.

[0038] Throughout the specification, like drawing reference numerals refer to like or similar elements. Also, the terms used in the specification are intended to describe embodiments, and are not intended to limit the present disclosure. As used herein, the singular forms are intended to include the plural forms, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," as used herein, specify the presence of stated elements, steps, operations, and / or apparatus, but do not preclude the presence or addition of other elements, steps, operations, and / or apparatus.

[0039] In an electric vehicle, there is no internal combustion engine that can be used as a heat source and a power source (a driving source such as a compressor or a pump), and an electric heater, an electric compressor, an electric pump, or the like must be used, and thus the use of electric power is very high compared to a general internal combustion engine vehicle.

[0040] In particular, for an electric vehicle, the proportion of energy consumed for cooling and heating is high, resulting in high loss of driving range. Therefore, it is important to improve thermal efficiency through indoor thermal management.

[0041] To this end, it is considered to apply a vacuum thermal insulator to a vehicle component, but when a known vacuum thermal insulator is used, it is difficult to be formed or processed into a desired shape due to initial stiffness.

[0042] Figure 1 To show a cross-sectional view of a component to which a vacuum thermal insulator according to the present disclosure is applied, and a cross-sectional view of a roof structure 9 configured by installing a roof duct 10 to a roof inner liner 2 of a vehicle.

[0043] As shown in the drawing, heat exchange occurs between the inside and the outside of the vehicle through a roof panel 1 of the vehicle, and a roof duct 10 for air conditioning is attached to an outer surface of the roof inner liner, which is a non-exposed surface of the roof inner liner 2.

[0044] The outer surface of the roof inner liner is an upper surface of the roof inner liner 2 in the drawing. If the surface exposed to the inside in the roof inner liner 2 is an inner surface based on the inside of the vehicle, then the opposite surface thereof, that is, an outer surface based on the inside of the vehicle among the two surfaces of the roof inner liner, is the outer surface of the roof inner liner to which the roof duct 10 is installed.

[0045] The roof duct 10 is a component for air conditioning installed to the outside of the roof inner liner 2 in the vehicle, and is a component configured to receive heating air for indoor heating or cooling air for indoor cooling from an air conditioning device (not shown) and guide the air to a roof vent 3 to be discharged inward.

[0046] When the roof duct 10 is installed to the outer surface of the roof liner 2, a flow path space through which air is guided to pass is formed by the outer surface of the roof liner 2 and the inner surface of the roof duct 10, and air supplied from the air conditioning device moves along the flow path space and is guided to the roof vent 3, and then is discharged to the inside of the vehicle from the roof vent 3.

[0047] The internal space of the roof duct 10, which is the flow path space, is communicated with the inside of the vehicle through the opening of the roof liner 2 and the roof vent 3 provided to the opening. Due to this structure, in summer, heat can flow from the outside of the vehicle to the inside of the vehicle through the roof duct 10 and the roof vent 3. On the contrary, in winter, heat can be dissipated from the inside of the vehicle to the outside of the vehicle through the roof vent 3 and the roof duct 10.

[0048] In order to prevent such heat inflow and heat loss, the roof duct 10 must be made of a material having a low thermal conductivity and excellent heat insulation performance. In the present disclosure, the use of the roof duct 10 made of a vacuum heat insulator can improve the roof heat insulation effect and the air conditioning performance. Further, the use of the roof duct 10 made of a vacuum heat insulator makes it possible to improve the thermal efficiency and the comfort of the inside of the vehicle, improve the energy efficiency, and increase the driving range.

[0049] The portion in which heat inflow and heat loss are large in the vehicle is the glass, and the second is the roof, the door, and the floor. In consideration of the fact that a large amount of heat inflow and heat loss can occur in the roof, in the present disclosure, the roof duct 10, which is the main path of heat inflow and heat loss, is manufactured using a vacuum heat insulator having excellent heat insulation performance. The thermal conductivity of the vacuum heat insulator is much lower than that of PET felt or polyurethane (PU) foam.

[0050] Figure 2 An application state of a vehicle component using a vacuum heat insulator according to the present disclosure is shown, and it is a plan view showing a state in which the roof duct 10, which is a vehicle component to which the vacuum heat insulator is applied, is installed to the roof structure 9. As shown in the drawing, the roof structure includes a roof duct attached to and installed to the outer surface of a predetermined region in the roof liner.

[0051] In Figure 2 , the shape of the roof duct 10 or the roof structure 9 including the same is illustrative, and the present disclosure is not limited to the illustrated example, and the shape of the roof duct 10 or the roof structure 9 can be changed.

[0052] Figure 3 A cross-sectional view showing the configuration of the vacuum heat insulator according to the embodiment of the present disclosure. In Figure 3In the drawings, reference numeral '14' indicates an edge portion of the outer shell material 13 of the vacuum insulation body 10a, which will be described later. The vacuum insulation body 10a can be used as an interior material of a vehicle, or can be used to manufacture a vehicle component having a predetermined shape, such as a roof duct.

[0053] As shown in the drawings, the vacuum insulation body 10a according to the embodiment of the disclosure includes a vacuum insulation layer 11 including an insulator 12, and in which an internal space in which the insulator 12 is located is maintained in a vacuum, and a shape-maintaining support 15 provided in a structure inserted into the insulator 12 of the vacuum insulation layer 11.

[0054] Here, the support 15 is used by being formed and processed to have a predetermined 3D shape, and serves as a fixing layer that maintains the shape of a component in the vacuum insulation body 10a, and supports vacuum pressure while enabling the 3D shape of the component to be implemented. The support 15 can be made of a metal plate that can be formed into a predetermined shape.

[0055] In the disclosure, the support 15 can be made of a metal plate containing aluminum. In the case of using a pure aluminum plate as the support 15, it is difficult to sufficiently play a role of supporting its shape due to insufficient strength, and in particular, shape change can be caused by vacuum.

[0056] Therefore, in the embodiment of the disclosure, the support 15 can be made of an aluminum alloy plate mainly containing aluminum (Al), or can be made of a stainless steel (SUS) plate that is an alloy plate mainly containing iron (Fe) as a light alloy plate.

[0057] Further, the support 15 can be manufactured by press-molding a metal plate into a predetermined 3D shape, considering a desired component shape. Here, the metal plate can be a perforated plate in which a plurality of holes are formed.

[0058] After forming holes in the metal plate at a predetermined size and interval by perforation, the perforated metal plate is press-molded to manufacture the support 15 having a desired shape. In this way, holes can be formed in the metal plate at a regular size and interval.

[0059] The vacuum insulation layer 11 includes the insulator 12 stacked on each of both sides of the support 15, and the outer shell material 13 configured to seal the insulator 12 to surround it in a vacuum. Here, the outer shell material 13 can have gas barrier properties so that an internal space in which the insulator 12 and the support 15 are accommodated can be maintained in a vacuum.

[0060] The vacuum insulation body 10a thus configured can be manufactured by stacking the insulator 12 on each of both sides of the support 15, stacking the outer shell material 13 on the outer surface of the insulator, and then joining the insulator 12, the outer shell material 13, and the support into one body through a vacuum compression process.

[0061] Glass wool can be used as the thermal insulator 12, and fibrous light glass wool is stacked on each of the two sides of the support 15, after which the outer shell material 13 is stacked around the glass wool, followed by vacuum compression, thereby integrating the support 15, the thermal insulator 12, and the outer shell material 13.

[0062] A metal-stacked composite film can be used as the outer shell material 13 bonded to the outer surface of the thermal insulator. Specifically, an aluminum composite film in which aluminum (Al) is stacked to a predetermined thickness on the surface of a film material can be used.

[0063] Here, the aluminum composite film can be manufactured by depositing aluminum (Al) to a predetermined thickness on the surface of a film material through an aluminum deposition process. The outer shell material 13 can be used to seal the thermal insulator 12, maintain the vacuum degree of the vacuum thermal insulation layer 11, and reflect heat transferred from the outside.

[0064] The film material of the outer shell material 13 can be a polyolefin film, and when using an outer shell material in which metal is deposited on a polyolefin film, the gas barrier property of the outer shell material can be additionally improved, so that the vacuum state of the vacuum thermal insulation layer 11 can be maintained for a long time.

[0065] Although the above describes using an aluminum composite film in which aluminum is deposited on the surface of a film material as the outer shell material 13, a metal composite film in which any one metal selected from gold, silver, copper, nickel, cobalt, chromium, and tin is deposited on the surface of a film material instead of aluminum can be used as the outer shell material.

[0066] Thereby, a vehicle component can be provided, which is formed of the above-described vacuum thermal insulator 10a, so that a change in thermal characteristics can be minimized, and an excellent thermal insulation effect between the inside and the outside of a vehicle can be exhibited, for example, a thermal insulating roof duct installed to the roof of a vehicle to reduce heat inflow and heat loss between the inside and the outside can be provided.

[0067] Figure 4 A schematic view of an arrangement of supports in a vacuum thermal insulator according to an embodiment of the disclosure, and Figure 5 An arrangement of supports in a vacuum thermal insulator according to a comparative example is schematically shown.

[0068] As Figure 4 As shown, after the thermal insulator 12 is stacked on each of the two sides of the support 15, the outer shell material 13 is vacuum-compressed to completely surround the stacked thermal insulator 12, thereby completely integrating the support 15 and the thermal insulator 12. Thereby, a plate-shaped vacuum thermal insulator 10a having a predetermined thickness can be manufactured.

[0069] In the vacuum insulation body 10a according to the embodiment of the present disclosure, the support 15 and the outer shell material 13 do not directly contact each other. Specifically, the support 15 is located in the inner space of the vacuum insulation layer 11 and is inserted in the substantially middle position between the outer shell materials 13 and the insulation 12 on both sides in the thickness direction of the vacuum insulation body, and the support 15 and the outer shell material 13 are spaced apart from each other as a whole with the insulation 12 interposed therebetween, even in the vacuum compressed state.

[0070] However, as in the comparative example of Figure 5 , when the support 15 and the outer shell material 13 in the vacuum insulation body 10a directly contact each other, a problem can occur in which the outer shell material 13 is torn at the corners of the support 15.

[0071] Therefore, the insulation 12 is preferably interposed between the support 15 and the outer shell material 13. In this way, the support 15 is preferably located in the middle position between the outer shell materials 13 on both sides in the vacuum insulation layer 11.

[0072] Figure 6 A process of manufacturing a vehicle component according to the embodiment of the present disclosure is shown, including a step of manufacturing a roof duct made of a vacuum insulation body according to the present disclosure.

[0073] As shown in Figure 6 , first, forming of a metal plate serving as a support is performed (①). Here, after a perforated plate is manufactured by perforating a metal plate, the perforated plate is pressed and formed into a predetermined shape according to the shape of the roof duct.

[0074] Next, external trimming to remove unnecessary portions from the formed metal plate is performed (②), and a sealing process for applying an adhesive for bonding to the insulation, such as a heat-resistant hot melt, etc., to predetermined portions such as an edge portion, etc., of the metal plate (perforated plate) 15a subjected to external trimming is performed (③).

[0075] Next, the insulation 12 having a predetermined thickness is cut into a desired size and shape (④), and the insulation 12 is stacked on each of both sides of the metal plate 15a (⑤). In addition, in the case where the insulation is stacked on the metal plate, the outer shell material is stacked on the outer surface of the insulation. Here, the outer shell material having a size that can completely cover the insulation on each side is stacked.

[0076] Next, the stacked metal plate 15a, which is a support, the insulation 12, and the outer shell material are placed in a vacuum exhaust device to have a vacuum of a predetermined pressure level, and all gases and moisture contained in the inner side sealed with the outer shell material and the insulation are exhausted to the outer side, and the outer shell material is sealed (⑥).

[0077] In this way, each shell material is vacuum compressed into the insulation by performing a vacuum compression process that applies vacuum pressure between the shell materials on both sides and applies heat and pressure to the shell materials, thereby integrating the support, insulation and shell materials.

[0078] Here, the stacked support, insulation, and outer shell material are formed into plates of a predetermined thickness, and at the edges of the outer shell material on both sides ( Figure 3 The figures (reference numeral '14') are fixed together in a state of thermal bonding. Next, by cutting and removing unnecessary parts of the outer shell material 13, external finishing is performed to change the incomplete shape of the appearance into a predetermined shape (⑦).

[0079] Next, finishing work is performed, such as additional molding, to attach the roof ducts (described later) to the roof liner. Figure 7 and 8 The edge of the figure mark '10' in the figure ( Figure 7 and 8 The shape of the part (represented by reference numeral '10b') or the bend is formed into a predetermined shape, or the individual shell material is attached to some parts to finally complete the part (⑧).

[0080] Figure 7 and 8 The process of attaching a roof duct made of vacuum insulation according to this disclosure to the roof liner is shown.

[0081] In the roof duct 10, an edge portion 10b is formed along the entire circumference of the edge of the roof duct. This edge portion has a shape that can be adhesively and fixedly disposed on the outer surface of the roof liner 2, and the edge portion 10b is adhesively bonded and fixed to the outer surface of the roof liner 2. Here, the roof liner 2 may be made of polyurethane sheet (PU sheet).

[0082] If the roof tube is made of polyurethane as is the conventional case, then a heat-resistant hot melt material can be applied as an adhesive to the edge of the roof tube, and then the edge of the roof tube can be bonded to the outer surface of the roof liner by applying heat and pressure, thereby fixing the edge of the roof tube to the outer surface of the roof liner by the hot melt material.

[0083] However, in this disclosure, a vacuum insulation material including an aluminum composite film as the outer shell material 13 is used. Figure 3 The roof pipe 10 is manufactured using reference numeral '10a' in the attached drawings. Therefore, taking this into consideration, in this disclosure, as... Figure 7As shown, a silicone adhesive is applied to the edge portion 10b of the roof duct 10 made of the vacuum thermal insulator, and then the edge portion 10b of the roof duct 10 can be adhered and fixed to the outer surface of the roof liner 2 by the silicone adhesive. Here, the silicone adhesive can be sufficiently cured at room temperature, so that the roof duct 10 is firmly adhered to the outer surface of the roof liner 2.

[0084] Alternatively, as shown, a heat-resistant tape, for example, a heat-resistant tape made of silicone, glass fiber, or polytetrafluoroethylene, can be adhered and fixed to the edge portion 10b of the roof duct 10, a heat-resistant hot melt, which is an adhesive, can be applied to the heat-resistant tape, and then the edge portion 10b of the roof duct 10 can be bonded to the roof liner 2 by simultaneously applying heat and pressure, thereby adhering and fixing the edge portion 10b of the roof duct 10 to the surface of the roof liner 2 by the heat-resistant hot melt. Figure 8

[0085] As described above, according to the present disclosure, a vacuum thermal insulator vehicle roof duct having excellent thermal insulation performance can be manufactured compared to a conventional roof duct made of a polyurethane board (PU board).

[0086] Further, a vacuum thermal insulator having excellent sound and thermal insulation performance and being easily shaped or processed into a desired part shape can be provided. In particular, even when a vacuum thermal insulator that is difficult to shape due to initial rigidity is used, a vehicle part having a desired shape can be manufactured.

[0087] The vacuum thermal insulator according to the present disclosure can be applied to manufacture a roof duct for air conditioning of a roof installed into a vehicle part, and when applied, it becomes possible to form a desired roof duct shape.

[0088] Further, according to the present disclosure, the range of application of the vacuum thermal insulator to vehicle parts can be increased and expanded, and when applied, the thermal management efficiency of the vehicle can be improved, and the driving range of the vehicle can also be increased.

[0089] Further, in the present disclosure, the thickness and size of the roof duct can be optimized by applying the vacuum thermal insulator, so that the vehicle interior space on the roof side can be sufficiently secured and expanded.

[0090] Further, when the present disclosure is applied, even when the roof panel is heated by external heat, the heat can be effectively blocked in the roof duct region to which the vacuum thermal insulator is applied, so the inside comfort can be improved.

[0091] As is apparent from the above description, according to the present disclosure, a vacuum thermal insulator having excellent sound and thermal insulation performance and being easily shaped or processed into a desired part shape can be provided. In particular, even when a vacuum thermal insulator that is difficult to shape due to initial rigidity is used, a vehicle part having a desired shape can be manufactured.​

[0092] A vacuum insulation body according to the present disclosure can be applied to manufacture a roof duct for air conditioning of a roof mounted into a vehicle part, and when applied, it becomes possible to form a desired roof duct shape.

[0093] Furthermore, according to the present disclosure, the range of application of a vacuum insulation body to a vehicle part can be increased and expanded, and when applied, the thermal management efficiency of a vehicle can be improved, and the driving range of the vehicle can also be increased.
