Technical Field

[0001] This utility model belongs to the field of corrugated tubes, specifically relating to a stainless steel corrugated tube with strong thermal conductivity. Background Technology

[0002] A corrugated pipe, also known as a bellows pipe, is a cylindrical thin-walled elastic pipe with a periodically corrugated surface. Its core structure consists of alternating straight pipe sections and arc-shaped corrugations, forming a unique flow channel design.

[0003] When installing long corrugated pipes, multiple corrugated pipes are often spliced ​​together. To improve the reusability of the pipes, detachable joints are often used. Chinese utility model patent "CN218179742U" discloses a stainless steel corrugated pipe with good thermal conductivity. By preventing scale residue from remaining on the inner wall, it ensures good heat conduction. It is also convenient to connect and use, and can be assembled without tools, improving installation efficiency. It is also easy to disassemble, which facilitates later maintenance and repair. It avoids the problems of rusting or stripping caused by bolt fixing, ensuring safety and service life.

[0004] However, the excessive number of components at the connection points of the aforementioned corrugated tubes can easily affect the heat exchange at these points, thus impacting the overall thermal conductivity of the corrugated tube. Therefore, there is an urgent need for a stainless steel corrugated tube with high thermal conductivity to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, where too many components are set at the connection of the corrugated tube, which can easily affect the heat exchange at the connection and the overall thermal conductivity of the corrugated tube, thereby realizing a stainless steel corrugated tube with strong thermal conductivity.

[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is: a stainless steel corrugated tube with strong thermal conductivity, comprising a straight tube, wherein a plurality of turbulence protrusions are provided on the straight tube to increase the contact area between the fluid inside the straight tube and the outside, a front connecting tube is integrally formed at the front end of the straight tube, a rear connecting tube is integrally formed at the rear end of the straight tube, and a connecting component is provided between the front connecting tube and the rear connecting tube.

[0007] In the aforementioned stainless steel corrugated tube with high thermal conductivity, the connecting assembly includes an elastic groove formed on the rear connecting tube, supports fixed on both sides of the elastic groove and on the rear connecting tube, two supports arranged in parallel, and a connecting frame arranged in parallel between the two supports, the connecting frame being fixed to the front connecting tube.

[0008] In the aforementioned stainless steel corrugated tube with high thermal conductivity, the connecting bracket has a hole for accommodating the threaded portion of the fixing bolt, and a mounting hole is provided on the bracket parallel to the hole. A fixing nut is threaded onto the threaded portion of the fixing bolt, and two brackets are disposed between the fixing bolt and the fixing nut.

[0009] In the aforementioned stainless steel corrugated tube with high thermal conductivity, slots are provided at both ends of the straight tube. An upper protective shell is provided at the top of the straight tube, and locking strips for locking onto the corresponding slots are fixedly connected to both the front and rear sides of the upper protective shell. Similarly, a lower protective shell is provided at the bottom of the straight tube, and the same locking strips are fixedly connected to both the front and rear sides of the lower protective shell. The upper protective shell and the lower protective shell form a cavity.

[0010] In the aforementioned stainless steel corrugated tube with high thermal conductivity, a protrusion is provided at the lower part of the lower protective shell, and the protrusion is located at the front end of the rear connecting tube.

[0011] In the aforementioned stainless steel corrugated tube with strong thermal conductivity, the front end of the front connecting tube is provided with a ramp, and the ramp is inclined.

[0012] In the aforementioned stainless steel corrugated tube with high thermal conductivity, the upper protective shell has lifting lugs integrally formed at both ends, and similarly, the lower protective shell has the same lifting lugs integrally formed at both ends. Furthermore, the lifting lugs have more than one through hole, and the upper protective shell and the lower protective shell are fixedly connected by bolts and nuts.

[0013] Compared with the prior art, the stainless steel corrugated tube with strong thermal conductivity of this invention has at least the following beneficial effects: This invention relates to a stainless steel corrugated tube with high thermal conductivity. By setting the connecting assembly, the front and rear connecting pipes are connected to form a continuous pipe. The connection point has a shape similar to the turbulence protrusion, which disrupts the fluid boundary layer at the pipe connection, enhances turbulence intensity, and improves the thermal conductivity at the pipe connection, thereby improving the overall thermal conductivity of the pipe. At the same time, the connection between the two corrugated tubes is a direct connection between the front and rear connecting pipes, avoiding the use of excessively thick connecting parts that would hinder heat exchange of the fluid flowing through the corrugated tube connection.

[0014] This invention relates to a stainless steel corrugated tube with strong thermal conductivity. By setting the lower protective shell and the protrusion, some substances that can react with the fluid in the corrugated tube are pre-placed inside the protrusion. When it is necessary to determine whether there is a leak between the front connecting pipe and the rear connecting pipe, it is only necessary to observe the reaction of the substances inside the protrusion. The operation is simple.

[0015] This utility model features a stainless steel corrugated pipe with strong thermal conductivity. By setting the upper and lower protective shells to form a cavity, the hot air is retained inside the cavity formed by the upper and lower protective shells, reducing the flow of hot air and ensuring the temperature stability at the corrugated pipe connection, thereby ensuring heat exchange at the corrugated pipe connection.

Detailed Implementation

[0018] The stainless steel corrugated tube with strong thermal conductivity of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] This embodiment discloses a stainless steel corrugated pipe with strong thermal conductivity. By setting the connecting assembly 11, the front connecting pipe 3 and the rear connecting pipe 4 form a connected pipe. The connection point has a shape similar to the turbulence protrusion 1, allowing the corrugated pipe connection point to disrupt the fluid boundary layer at the pipe connection point, enhancing turbulence intensity and improving the thermal conductivity at the pipe connection point, thereby increasing the overall thermal conductivity of the pipe. Simultaneously, the connection between the two corrugated pipes uses a direct connection between the front connecting pipe 3 and the rear connecting pipe 4, avoiding the use of excessively thick connecting parts that could hinder heat exchange of the fluid flowing through the corrugated pipe connection point. (Refer to...) Figures 1-7 It mainly includes a straight pipe 2, on which several turbulence protrusions 1 are provided to increase the contact area between the fluid inside the straight pipe 2 and the outside. The front end of the straight pipe 2 is integrally formed with a front connecting pipe 3, and the rear end of the straight pipe 2 is integrally formed with a rear connecting pipe 4. The fluid flowing in the corrugated pipe enters the corrugated pipe through the front connecting pipe 3 and finally flows out of the corrugated pipe through the rear connecting pipe 4. A connecting component 11 is provided between the front connecting pipe 3 and the rear connecting pipe 4.

[0021] like Figure 7 As shown, the connecting assembly 11 includes an elastic groove 113 formed on the rear connecting pipe 4. Supports 111 are fixed to both sides of the elastic groove 113 on the rear connecting pipe 4. The two supports 111 are arranged in parallel, and a connecting frame 116 is arranged in parallel between the two supports 111. The connecting frame 116 is fixed to the front connecting pipe 3. The rear connecting pipe 4 is movably sleeved on the corresponding rear connecting pipe 3, and the relative movement of the two supports 111 causes the corresponding elastic groove 113 to contract, achieving a tight seal between the rear connecting pipe 4 and the outer surface of the front connecting pipe 3.

[0022] like Figure 7As shown, the connecting bracket 116 has a hole for accommodating the threaded portion of the fixing bolt 112, and a mounting hole 114 is provided on the bracket 111 parallel to the hole. A fixing nut 115 is threaded onto the threaded portion of the fixing bolt 112, and two brackets 111 are positioned between the fixing bolt 112 and the fixing nut 115. By using an external tool to move the fixing nut 115 toward the fixing bolt 112, relative movement is caused between the two brackets 111, thereby causing the elastic groove 113 to contract. Ultimately, this causes the rear connecting pipe 4 to tightly fit against the front connecting pipe 3, achieving a sealed installation between the corrugated pipes.

[0023] like Figures 3-5 As shown, the straight pipe 2 has slots 12 at both ends. The upper protective shell 6 has clips 8 fixedly connected to its front and rear sides for locking onto the corresponding slots 12. The upper protective shell 6 is located at the top of the straight pipe 2. Similarly, the lower protective shell 7 has clips 8 fixedly connected to its front and rear sides. The lower protective shell 7 is located at the bottom of the straight pipe 2. The upper protective shell 6 and the lower protective shell 7 form a cavity to reduce the flow of hot air and ensure the heating temperature of the fluid flowing through the cavity.

[0024] The lower part of the lower protective shell 7 is provided with a protrusion 10, such as Figure 6 As shown, the protrusion 10 is located at the front end of the rear connecting pipe 4, allowing fluid leaking between the front connecting pipe 3 and the rear connecting pipe 4 to better enter the interior of the protrusion 10 and react with the substance placed inside. This allows maintenance personnel to directly observe the reaction of the substance inside the protrusion 10 to confirm whether there is a leak between the front connecting pipe 3 and the rear connecting pipe 4. It should be noted that both the lower protective shell 7 and the upper protective shell 6 are made of transparent material. By setting the lower protective shell 7 and the protrusion 10, and pre-placing some substances that can react with the fluid in the corrugated pipe inside the protrusion 10, it is only necessary to observe the reaction of the substance inside the protrusion 10 when it is necessary to determine whether there is a leak between the front connecting pipe 3 and the rear connecting pipe 4, which is simple to operate.

[0025] like Figure 6As shown, the front end of the front connecting pipe 3 is provided with a ramp 5. The ramp 5 is inclined to facilitate the smooth flow of fluid entering the front connecting pipe 3 through the turbulence protrusion 1. That is, when the fluid transitions into the front connecting pipe 3, the direction of the scouring force on the front connecting pipe 3 changes from a single straight line to a force perpendicular to the fluid flow direction after contacting the ramp 5. This force can increase the outward expansion of the front connecting pipe 3, thereby making it fit more closely to the rear connecting pipe 4. Thus, the force of the fluid scouring the front connecting pipe 3 is converted and applied between the front connecting pipe 3 and the rear connecting pipe 4, improving the tightness between the front connecting pipe 3 and the rear connecting pipe 4.

[0026] The upper protective shell 6 has integrally formed lifting lugs 9 at both ends, and similarly, the lower protective shell 7 has integrally formed lifting lugs 9 at both ends. Furthermore, each lifting lug 9 has more than one through hole. The upper protective shell 6 and the lower protective shell 7 are fixedly connected by bolts and nuts. By creating a cavity between the upper protective shell 6 and the lower protective shell 7, hot air is retained inside the cavity, reducing the flow of hot air and ensuring temperature stability at the corrugated pipe connection, thereby guaranteeing heat exchange at the corrugated pipe connection.

[0027] The working principle of this novel stainless steel corrugated tube with strong thermal conductivity is as follows: When it is necessary to connect two corrugated tubes; First, the straight pipe 2 is moved by an external force. The movement of the straight pipe 2 causes the corresponding front connecting pipe 3 to move into the interior of the rear connecting pipe 4 corresponding to the other straight pipe 2. The bracket 111 and the connecting frame 116 are arranged parallel to each other. Then, the fixing bolt 112 and the fixing nut 115 are installed on the rear connecting pipe 4 and the front connecting pipe 3 by using external tools.

[0028] Secondly, the upper protective shell 6 and the lower protective shell 7 are moved, and the movement of the upper protective shell 6 and the lower protective shell 7 causes the corresponding card strip 8 to move into the corresponding card slot 12.

[0029] It should be noted that, in actual implementation, the structure depicted in the accompanying drawings is not a fixed or unchanging embodiment. The components of the embodiments of this invention described and shown in these drawings can typically be arranged and designed in various different configurations. Furthermore, the accompanying drawings and abstract drawings are merely illustrative and do not represent the specific structure or actual quantity in a concrete implementation.
