Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a high-strength HPVC double-wall corrugated pipe with a heat dissipation structure. Background Technology

[0002] In the field of pipeline engineering, especially in scenarios involving the transportation of fluid media, such as water supply and drainage, and chemical raw material transportation, there are many stringent requirements for pipeline performance. Traditional pipelines have many limitations in structure and function, making it difficult to simultaneously meet the demands for high strength, good heat dissipation, and convenient installation and connection.

[0003] In terms of strength and protection: Traditional single-layer pipelines are prone to damage when facing complex operating environments, such as external impacts, compression, and long-term exposure to environmental factors (such as ultraviolet rays and chemical corrosion). This can lead to pipeline rupture, leakage, and other problems, affecting the normal operation and service life of the pipeline, and may even cause safety accidents.

[0004] Regarding heat dissipation performance: When the temperature of the medium transported in the pipeline is high, the pipeline itself will accumulate a large amount of heat. Due to structural limitations, traditional pipelines have poor heat dissipation, and the heat cannot be dissipated in time, causing the internal temperature of the pipeline to continue to rise. This not only increases the risk of pipeline material damage due to thermal expansion, but may also affect the physical and chemical properties of the medium, reduce transportation efficiency, and even cause quality damage to some temperature-sensitive media.

[0005] Regarding installation and connection: Traditional pipelines often involve complex connection methods between adjacent pipes during installation, making the operation difficult and requiring significant manpower and time. Furthermore, the sealing and stability of the connections are difficult to guarantee, easily leading to loose connections, leaks, and other problems, increasing the maintenance costs and safety risks of the pipeline system.

[0006] The purpose of this invention is to provide a high-strength HPVC double-wall corrugated pipe with a heat dissipation structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-strength HPVC double-wall corrugated pipe with a heat dissipation structure, comprising an inner pipe and an HPVC corrugated pipe sleeved on the outside of the inner pipe, wherein a support strip is fixed between the inner pipe and the HPVC corrugated pipe, and multiple sets of reserved openings are opened on the surface of the HPVC corrugated pipe, and metal mesh is fixed inside the reserved openings.

[0008] Preferably, the inner tube and the HPVC corrugated pipe have the same length. One end of the inner tube is integrally formed with an extension socket, and one end of the HPVC corrugated pipe is integrally formed with an extension corrugation. A gap is reserved between the extension socket and the extension corrugation, and a support ring is fixed between the extension socket and the extension corrugation. The outer diameter of the extension socket is greater than the outer diameter of the inner tube, and the outer diameter of the extension corrugation is greater than the outer diameter of the HPVC corrugated pipe.

[0009] Preferably, a plurality of through holes are provided on the surface of the support ring.

[0010] Preferably, there are a plurality of support bars, and the plurality of support bars are circumferentially distributed around the inner tube as the central axis.

[0011] Preferably, the reserved opening is a "convex"-shaped arc groove. There are a plurality of each group of reserved openings, and the plurality of reserved openings are circumferentially distributed around the HPVC corrugated pipe as the central axis. The metal mesh covers the notch at one end of the reserved opening away from the inner tube.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The high-strength HPVC double-wall corrugated pipe with a heat dissipation structure proposed by the present utility model provides an effective channel for the dissipation of heat inside the pipe through multiple groups of "convex"-shaped arc groove reserved openings provided on the surface of the HPVC corrugated pipe. The heat generated during the process of the inner tube transporting the medium can be transferred to the reserved openings through air convection, and then dissipated into the external environment, effectively reducing the temperature inside the pipe and avoiding problems such as damage to the pipe material and change in the properties of the medium caused by heat accumulation.

[0014] The extension socket integrally formed at one end of the inner tube and the extension corrugation integrally formed at one end of the HPVC corrugated pipe facilitate the connection of two adjacent inner tubes. During the installation process, only need to insert the extension socket of one pipe into the extension corrugation of another pipe to achieve the pre-connection of two adjacent inner tubes. The operation is simple and fast, greatly improving the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a high-strength HPVC double-wall corrugated pipe with a heat dissipation structure, including an inner pipe 1 and an HPVC corrugated pipe 2 sleeved on the outside of the inner pipe 1. A support bar 3 is fixed between the inner pipe 1 and the HPVC corrugated pipe 2. The pipe bodies of the inner pipe 1 and the HPVC corrugated pipe 2 are of equal length. An extension sleeve 6 is integrally formed at one end of the inner pipe 1, and an extension corrugated pipe 7 is integrally formed at one end of the HPVC corrugated pipe 2. A gap is reserved between the extension sleeve 6 and the extension corrugated pipe 7, and a support ring 8 is fixed between the extension sleeve 6 and the extension corrugated pipe 7. The outer diameter of the extension sleeve 6 is larger than the outer diameter of the inner pipe 1, and the outer diameter of the extension corrugated pipe 7 is larger than the outer diameter of the HPVC corrugated pipe 2. Multiple support bars 3 are provided, and the multiple support bars 3 are circumferentially distributed with the inner pipe 1 as the central axis. Multiple through holes 9 are opened on the surface of the support ring 8.

[0024] In use, the inner pipe 1 and the HPVC corrugated pipe 2 form a double-layer pipe structure. The HPVC corrugated pipe 2 protects the inner pipe 1 and also acts as an anti-impact buffer for the inner pipe 1. A support strip 3 is installed between the inner pipe 1 and the HPVC corrugated pipe 2 to connect the inner pipe 1 and the HPVC corrugated pipe 2. The reason for setting the extension sleeve 6 and the extension corrugated pipe 7 at the ends of the inner pipe 1 and the HPVC corrugated pipe 2 respectively is to facilitate the pre-connection of two adjacent inner pipes 1 by sleeve.

[0025] Multiple sets of pre-drilled openings 4 are formed on the surface of the HPVC corrugated pipe 2, and a metal mesh 5 is fixed inside the pre-drilled openings 4. The pre-drilled openings 4 are convex arc grooves, and each set of pre-drilled openings 4 has multiple openings. The multiple pre-drilled openings 4 are distributed circumferentially around the central axis of the HPVC corrugated pipe 2. The metal mesh 5 covers the end of the pre-drilled opening 4 that is away from the inner pipe 1. The reason for forming pre-drilled openings 4 on the outer wall of the HPVC corrugated pipe 2 is to dissipate the heat emitted from the surface of the inner pipe 1 without affecting the protective effect of the HPVC corrugated pipe 2 on the inner pipe 1.

[0026] Instructions for using high-strength HPVC double-wall corrugated pipes with heat dissipation structure: During installation, adjacent pipes need to be connected. Since the inner pipe 1 has an extension sleeve 6 at one end and the HPVC corrugated pipe 2 has an extension corrugated pipe 7 at the other end, the extension sleeve 6 of one pipe can be inserted into the extension corrugated pipe 7 of the other pipe to achieve a pre-connection of the two adjacent inner pipes 1. This pre-connection method facilitates subsequent sealing and fixing operations, ensuring the integrity and stability of the pipe connection. After pre-connection, the connection area needs to be sealed to prevent media leakage. Special sealant or sealing kits can be used to seal and fill the gap between the extension sleeve 6 and the extension corrugated pipe 7 to ensure a good seal. Simultaneously, depending on the actual project requirements, clamps, bolts, and other fasteners can be used to reinforce the connection area, enhancing the reliability of the pipe connection and preventing loosening or separation due to external forces during use. The inner pipe 1 generates heat during media transport, which is conducted through the inner pipe 1 wall to the space between the inner pipe 1 and the HPVC corrugated pipe 2. Because of the gaps between the support bars 3, air can flow through them, forming air convection, which helps with heat transfer. Simultaneously, the reserved opening 4 on the surface of the HPVC corrugated pipe 2 communicates with the external environment. Heat emitted from the inner pipe 1 is transferred to the reserved opening 4 through air convection, and then dissipated into the external environment via the metal mesh 5. The through holes 9 on the surface of the support ring 8 further promote airflow within the pipe, enhancing heat dissipation. The metal mesh 5 covers the end of the reserved opening 4 furthest from the inner pipe 1, ensuring airflow while effectively preventing dust and debris from entering the pipe, avoiding damage to the internal structure and ensuring that the pipe's normal operation and service life are not affected by debris during heat dissipation. Furthermore, the "convex" shaped arc groove design of the reserved opening 4 increases the contact area with the outside air, further improving heat dissipation efficiency, allowing the heat generated by the inner pipe 1 to dissipate more quickly and effectively, maintaining a stable internal temperature and ensuring the normal operation of the pipe.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
