Description
Technical Field
[0001] The utility model relates to the field of automobile intake pipes, and particularly relates to an automobile intake pipe with a heat preservation protective layer. Background Art
[0002] Automobile intake pipes. Therefore, it is very necessary to invent an automobile intake pipe with a heat preservation protective layer to solve the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to provide an automobile intake pipe with a heat preservation protective layer to solve the problems put forward in the above background art.
[0004] To achieve the above purpose, the utility model provides the following technical scheme: an automobile intake pipe with a heat preservation protective layer, which includes an intake pipe body. One end of the intake pipe body is an air outlet end, and the other end is an air inlet end. The outside of the intake pipe body is covered with a heat preservation pipe. The heat preservation pipe includes a ceramic fiber layer, a carbon fiber layer, an aluminized fiber cloth layer and a SUS304 embossed plate. The ceramic fiber layer, the carbon fiber layer and the aluminized fiber cloth layer are sleeved on the intake pipe body from the inside to the outside, and the ceramic fiber layer, the carbon fiber layer and the aluminized fiber cloth layer are wound on the intake pipe body with tie straps. The SUS304 embossed plate is welded to the intake pipe body.
[0005] Preferably, the original thickness of the ceramic fiber layer is 10 mm, and it is compressed to 8 mm after being sleeved on the intake pipe body.
[0006] In the utility model, the outside of the intake pipe body is covered with a heat preservation pipe, and the heat preservation pipe aims to increase the heat preservation performance of the intake pipe body.
[0007] The fixing method of the heat preservation pipe in the utility model: first, use tie straps to wind and fix the ceramic fiber layer, the carbon fiber layer and the aluminized fiber cloth layer on the intake pipe body, and weld the SUS304 embossed plate on the intake pipe body to wrap the whole.
[0008] Preferably, the thickness of the carbon fiber layer is 1.5 mm.
[0009] In the present utility model, the original thickness of the ceramic fiber layer is 10 mm. After the ceramic fiber layer is sleeved on the intake pipe body, it is compressed to 8 mm, further enhancing the heat preservation performance of the ceramic fiber layer itself. The ceramic fiber layer serves the purpose of heat insulation, achieving the initial goal of preventing the heat in the intake pipe body from dissipating. The carbon fiber layer aims to enhance the heat preservation performance of the intake pipe body, enabling the outer circle of the ceramic fiber layer to have a heat preservation structure and avoiding the phenomenon of rapid heat dissipation on the ceramic fiber layer. The heat on the ceramic fiber layer will not dissipate quickly, making it difficult for the heat inside the intake pipe body to quickly escape through the intake pipe body and the wall of the ceramic fiber layer. The thickness of the ceramic fiber layer is greater than that of the carbon fiber layer, meeting the initial requirement of high heat insulation.
[0010] Preferably, the thickness of the aluminized fiber cloth layer is 0.25 mm.
[0011] An aluminized fiber cloth layer is further provided outside the carbon fiber layer. On the one hand, the aluminized fiber cloth layer has the effect of heat preservation. On the other hand, it can prevent air from contacting the carbon fiber layer and the ceramic fiber layer, playing a role in preventing the oxidation of the pipeline structure.
[0012] Preferably, the thickness of the SUS304 embossed plate is 0.25 mm.
[0013] The SUS304 embossed plate increases the strength of the overall heat preservation pipe, avoiding the phenomenon that the structure of the heat preservation pipe is easily damaged when being pressed, meeting the strength requirement for pipeline use.
[0014] Preferably, the thickness of the heat preservation pipe is 10 mm.
[0015] The overall heat preservation pipe is 10 mm thick. The heat preservation pipe completely covers the outside of the intake pipe body, with a relatively small overall volume, reasonable design, and is convenient for transportation and storage.
[0016] Preferably, a concave area is provided on the surface of the aluminized fiber cloth layer, and a deformation member that expands when heated is fixedly arranged in the concave area.
[0017] To further enhance the heat preservation effect of the heat preservation pipe on the intake pipe body, a deformation member is arranged in the concave area. The deformation member can use materials such as thermosensitive metals, which are common existing materials and will not be elaborated here. When the deformation member is heated, it can expand and deform, thereby forming a vacuum chamber between the SUS304 embossed plate and the aluminized fiber cloth layer. The vacuum chamber increases the heat preservation effect of the heat preservation pipe on the intake pipe body. At normal temperature, the SUS304 embossed plate can recover its deformation and does not occupy space.
[0018] Preferably, when the deformation member expands due to heat, it becomes thicker, and the thicker deformation member pushes the SUS304 embossed plate away from the aluminized fiber cloth layer, forming a vacuum chamber between the SUS304 embossed plate and the aluminized fiber cloth layer.
[0019] It should be noted that welding sealing or glue sealing is required at the joints between the SUS304 embossed plate and the aluminum-coated fiber step layer to ensure that when the SUS304 embossed plate is stretched and deformed, the inside of the vacuum chamber can maintain a vacuum state. The insulation effect of the insulation pipe in this device will increase accordingly under high temperature conditions, and the structural design is reasonable.
[0020] Preferably, the deformable member includes a first deformable layer, a second deformable layer and a heat insulating layer, the heat insulating layer is fixed between the first deformable layer and the second deformable layer, the first deformable layer is fixed on one side of the SUS304 embossed plate close to the aluminum-plated fiber step layer, and the second deformable layer is fixed on the bottom of the recessed area.
[0021] Taking into account that when the temperature of the air intake pipe body and the insulation pipe is high, the heat in the air intake pipe body will be transferred through the deformable part. Therefore, the deformable part is set to have three layers: a first deformation layer, a second deformation layer, and a heat insulation layer. The heat insulation layer is blocked between the first deformation layer and the second deformation layer to block the heat. When the first deformation layer and the second deformation layer expand due to heat, the SUS304 embossed plate will be stretched open.
[0022] Preferably, the deformable member is distributed in a circle around the aluminum-plated fiber layer in an annular structure.
[0023] Because the deformable member is arranged on the air intake pipe body for use, the deformable member can be arranged into a suitable shape according to the actual shape of the air intake pipe body and can be adjusted according to actual use requirements.
[0024] Technical effects and advantages of the utility model:
[0025] 1. In the utility model, the outside of the air intake pipe body is covered with an insulation pipe, and the insulation pipe has the purpose of increasing the insulation performance of the air intake pipe body. The original thickness of the ceramic fiber layer in the utility model is 10mm. After the ceramic fiber layer is sleeved on the air intake pipe body, it is compressed to 8mm, so that the insulation performance of the ceramic fiber layer itself is further increased. The ceramic fiber layer has the purpose of heat insulation, and the purpose of initially avoiding the heat dissipation in the air intake pipe body is achieved. The carbon fiber layer has the purpose of increasing the insulation performance of the air intake pipe body, so that the outer ring of the ceramic fiber layer has an insulation structure to avoid the phenomenon of rapid heat loss on the ceramic fiber layer. The heat on the ceramic fiber layer will not be quickly dissipated, so that the heat inside the air intake pipe body is not easy to be quickly dissipated through the air intake pipe body and the ceramic fiber layer wall. The thickness of the ceramic fiber layer is greater than the thickness of the carbon fiber layer, which meets the purpose of high initial insulation requirements;
[0026] 2. An aluminum-plated fiber layer is also provided outside the carbon fiber layer. The aluminum-plated fiber layer has a heat preservation effect on the one hand, and on the other hand, it can prevent air from contacting the carbon fiber layer and the ceramic fiber layer, thereby preventing the pipeline structure from being oxidized;
[0027] 3. The SUS304 embossed plate increases the strength of the overall insulation pipe, avoiding the phenomenon that the insulation pipe structure is easily damaged when pressed, and meets the strength requirements for pipeline use;
[0028] 4. In order to further increase the insulation effect of the insulation pipe on the intake pipe body, a deformation piece is provided in the recessed area. The deformation piece can be made of materials such as heat-sensitive metals, which are common existing materials and will not be described here. When the deformation piece is heated, the deformation piece can expand and deform, so that a vacuum chamber is formed between the SUS304 embossed plate and the aluminum-plated fiber step layer. The vacuum chamber increases the insulation effect of the insulation pipe on the intake pipe body. At room temperature, the SUS304 embossed plate can restore its deformation and does not occupy space.
[0029] 5. Considering that when the temperature of the air intake pipe body and the insulation pipe is high, the heat in the air intake pipe body will be transferred through the deformation part. Therefore, the deformation part is set to have three layers: the first deformation layer, the second deformation layer, and the insulation layer. The insulation layer is blocked between the first deformation layer and the second deformation layer to block the heat. When the first deformation layer and the second deformation layer expand due to heat, the SUS304 embossed plate will be stretched open. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner
[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0042] The present utility model provides an automobile intake pipe with a heat preservation protection layer as Figures 1-10 shown, including an intake pipe body 1. One end of the intake pipe body 1 is an air outlet end 3, and the other end is an air inlet end 4. The outside of the intake pipe body 1 is coated with a heat preservation pipe 2. The heat preservation pipe 2 includes a ceramic fiber layer 21, a carbon fiber layer 22, an aluminized fiber cloth layer 23, and a SUS304 embossed plate 24. The ceramic fiber layer 21, the carbon fiber layer 22, and the aluminized fiber cloth layer 23 are sleeved on the intake pipe body 1 from the inside to the outside, and the ceramic fiber layer 21, the carbon fiber layer 22, and the aluminized fiber cloth layer 23 are wound on the intake pipe body 1 with cable ties. The SUS304 embossed plate 24 is welded to the intake pipe body 1.
[0043] The original thickness of the ceramic fiber layer 21 is 10 mm, and it is compressed to 8 mm after being sleeved on the intake pipe body 1.
[0044] In the present utility model, the outside of the intake pipe body 1 is coated with a heat preservation pipe 2, and the heat preservation pipe 2 aims to increase the heat preservation performance of the intake pipe body 1.
[0045] The fixing method of the heat preservation pipe 2 in the present utility model: first, use cable ties to wind and fix the ceramic fiber layer 21, the carbon fiber layer 22, and the aluminized fiber cloth layer 23 on the intake pipe body 1, and weld the SUS304 embossed plate 24 on the intake pipe body 1 to wrap the whole.
[0046] The thickness of the carbon fiber layer 22 is 1.5 mm.
[0047] In the present utility model, the original thickness of the ceramic fiber layer 21 is 10 mm. After the ceramic fiber layer 21 is sleeved on the intake pipe body 1, it is compressed to 8 mm, further enhancing the heat preservation performance of the ceramic fiber layer 21 itself. The ceramic fiber layer 21 serves the purpose of heat insulation, achieving the initial goal of preventing the heat in the intake pipe body 1 from dissipating. The carbon fiber layer 22 aims to enhance the heat preservation performance of the intake pipe body 1, creating a heat preservation structure on the outer ring of the ceramic fiber layer 21 and preventing the rapid dissipation of heat from the ceramic fiber layer 21. The heat on the ceramic fiber layer 21 will not dissipate quickly, making it difficult for the heat inside the intake pipe body 1 to rapidly escape through the wall of the intake pipe body 1 and the ceramic fiber layer 21. The thickness of the ceramic fiber layer 21 is greater than that of the carbon fiber layer 22, meeting the initial requirement of high heat insulation.
[0048] The thickness of the aluminized fiber cloth layer 23 is 0.25 mm.
[0049] An aluminized fiber cloth layer 23 is further provided outside the carbon fiber layer 22. On the one hand, the aluminized fiber cloth layer 23 has a heat preservation effect. On the other hand, it can prevent air from contacting the carbon fiber layer 22 and the ceramic fiber layer 21, playing a role in preventing the oxidation of the pipeline structure.
[0050] The thickness of the SUS304 embossed plate 24 is 0.25 mm.
[0051] The SUS304 embossed plate 24 increases the strength of the overall heat preservation pipe 2, avoiding the phenomenon that the structure of the heat preservation pipe 2 is easily damaged when being pressed, meeting the strength requirements for pipeline use.
[0052] The thickness of the heat preservation pipe 2 is 10 mm.
[0053] The overall heat preservation pipe 2 is 10 mm thick. The heat preservation pipe 2 completely wraps around the outside of the intake pipe body 1, with a relatively small overall volume, reasonable design, and is convenient for transportation and storage.
[0054] A concave area 231 is provided on the surface of the aluminized fiber cloth layer 23, and a deformation member 5 that expands when heated is fixedly arranged in the concave area 231.
[0055] In order to further enhance the heat preservation effect of the heat preservation pipe 2 on the intake pipe body 1, a deformation member 5 is arranged in the concave area 231. The deformation member 5 can be made of materials such as thermosensitive metal, which are common existing materials and will not be elaborated here. When the deformation member 5 is heated, it can expand and deform, thereby forming a vacuum chamber 6 between the SUS304 embossed plate 24 and the aluminized fiber cloth layer 23. The vacuum chamber 6 enhances the heat preservation effect of the heat preservation pipe 2 on the intake pipe body 1. At normal temperature, the SUS304 embossed plate 24 can recover its deformation and does not occupy space.
[0056] When the deformable part 5 expands due to heat, it becomes thicker. The thicker deformable part 5 pushes the SUS304 embossed plate 24 away from the aluminized fiber layer 23, creating a vacuum chamber 6 between the SUS304 embossed plate 24 and the aluminized fiber layer 23.
[0057] It should be noted that at the joints at both ends of the SUS304 embossed plate 24 and the aluminized fiber layer 23, welding or glue sealing treatment is required to ensure that when the SUS304 embossed plate 24 is deformed by being pushed open, the inside of the vacuum chamber 6 can maintain a vacuum state. In this device, the heat insulation effect of the heat insulation pipe 2 will increase correspondingly under high-temperature conditions, and the structural design is reasonable.
[0058] The deformable part 5 includes a first deformable layer 51, a second deformable layer 52, and a heat insulation layer 53. The heat insulation layer 53 is fixed between the first deformable layer 51 and the second deformable layer 52. The first deformable layer 51 is fixed on the side of the SUS304 embossed plate 24 close to the aluminized fiber layer 23, and the second deformable layer 52 is fixed at the bottom of the recessed area 231.
[0059] Considering that when the temperature of the intake pipe body 1 and the heat insulation pipe 2 is high, the heat in the intake pipe body 1 will be transferred through the deformable part 5. Therefore, the deformable part 5 is set to three layers: the first deformable layer 51, the second deformable layer 52, and the heat insulation layer 53. The heat insulation layer 53 blocks between the first deformable layer 51 and the second deformable layer 52 to block the heat. When the first deformable layer 51 and the second deformable layer 52 expand due to heat, they push the SUS304 embossed plate 24 open.
[0060] The deformable part 5 is distributed in a circular structure around the aluminized fiber layer 23.
[0061] Since the deformable part 5 is used on the intake pipe body 1, the deformable part 5 can be set into a suitable shape according to the actual shape of the intake pipe body 1 and adjusted according to actual use requirements.
[0062] Working principle: In the present utility model, the outside of the intake pipe body 1 is covered with a heat insulation pipe 2, and the heat insulation pipe 2 aims to increase the heat insulation performance of the intake pipe body 1.
[0063] The fixing method of the heat insulation pipe 2 in the present utility model: First, use cable ties to wind and fix the ceramic fiber layer 21, the carbon fiber layer 22, and the aluminized fiber layer 23 on the intake pipe body 1, and weld the SUS304 embossed plate 24 to the intake pipe body 1 to cover the whole.
[0064] In the present utility model, the original thickness of the ceramic fiber layer 21 is 10 mm. After the ceramic fiber layer 21 is sleeved on the intake pipe body 1, it is compressed to 8 mm, which further enhances the heat insulation performance of the ceramic fiber layer 21 itself. The ceramic fiber layer 21 serves the purpose of heat insulation, achieving the initial goal of preventing the heat in the intake pipe body 1 from dissipating. The carbon fiber layer 22 serves the purpose of enhancing the heat insulation performance of the intake pipe body 1, creating a heat insulation structure on the outer ring of the ceramic fiber layer 21 and preventing the phenomenon of rapid heat dissipation on the ceramic fiber layer 21. The heat on the ceramic fiber layer 21 will not dissipate quickly, so that the heat inside the intake pipe body 1 is not easily dissipated quickly through the wall bodies of the intake pipe body 1 and the ceramic fiber layer 21. The thickness of the ceramic fiber layer 21 is greater than that of the carbon fiber layer 22, meeting the initial requirement of high heat insulation.
