Description

Technical Field

[0001] The utility model relates to the technical field of circulating cold air pipes, in particular to a circulating cold air pipe with a high molecular polymer coated on the inner wall. Background Art

[0002] In many industrial applications, circulating air cooling pipes play a vital role, especially in places where cooling media need to be transferred or circulated. The material and structure of these cooling pipes play a key role in their performance and life. In order to improve their performance, the inner wall of circulating air cooling pipes is often coated with high molecular polymers.

[0003] The main purpose of coating with polymer is to prevent inner wall corrosion. Cooling media, especially certain chemical coolants, may react chemically with pipes, leading to corrosion of the inner wall of the pipe. By coating with polymer, the direct contact between the medium and the pipe can be effectively isolated, thereby slowing down or preventing corrosion.

[0004] However, there are still some problems with the existing circulating air conditioning pipes: first, the traditional pipe connection method may cause leakage at the connection due to wear, aging or improper installation, which not only wastes cooling medium but also may pollute the surrounding environment; second, the existing connection method may not be flexible enough, making it difficult to install or replace under certain specific working conditions or space constraints; finally, traditional pipe connections often require multiple parts and tools, which makes the installation process complicated and time-consuming.

[0008] Preferably, the hard layer is made of polymer ceramic material and is sprayed on the adhesive layer to improve the strength of the polymer coating.

[0009] Preferably, the texture layer is made of high molecular polymer material and is sprayed on the hard layer. The combination of micropores and microgrooves opened inside provides a larger surface area for the fluid, improves the heat transfer effect, and achieves a filtering effect.

[0010] Preferably, a plurality of ball head connecting rods are arranged in an annular array inside the end face sealing groove of the flange, the diameter of the ball head part of the ball head connecting rod is larger than the rod body diameter of the ball head connecting rod, and a plurality of clip-in grooves are opened in an internal circumferential array of the sealing belt, and the number of the clip-in grooves is twice the number of the ball head connecting rods, which are used to clip the sealing belt onto the ball head connecting rod.

[0023] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0024] Reference below Figure 1-5 A circulating cold air pipe with an inner wall coated with a polymer according to an embodiment of the utility model is described, comprising a pipe body 1, a polymer coating 2, a flange 3 and a sealing tape 4, the polymer coating 2 is coated on the inner wall of the pipe body 1, the polymer coating 2 is composed of an adhesive layer 21, a hard layer 22 and a texture layer 23, the adhesive layer 21, the hard layer 22 and the texture layer 23 are all annular, the adhesive layer 21 is connected to the inner wall of the pipe body 1, the hard layer 22 is fixedly connected to the inner wall of the adhesive layer 21, the texture layer 23 is fixedly connected to the inner wall of the hard layer 22, a spiral micro-groove structure is provided at the inner wall of the texture layer 23, and a plurality of micro-pores are longitudinally provided inside the texture layer 23, the micro-pores are connected to the micro-groove structure, the flange 3 is arranged at the end of the pipe body 1, and the flange 3 is integrally connected to the pipe body 1, a connecting hole is provided on the flange 3 for connecting multiple pipe bodies 1, a sealing groove is provided at the end face of the flange 3, and the sealing tape 4 is clamped in the sealing groove to ensure the sealing of the connection.

[0025] Specifically, the inner wall of the pipe body 1 is coated with a polymer coating 2, and the polymer coating 2 is divided into an adhesive layer 21, a hard layer 22 and a texture layer 23. The adhesive layer 21 directly contacts the pipe body 1 and is connected thereto, and the hard layer 22 is connected to the adhesive layer to further fix and enhance the stability of the adhesive layer 21. The texture layer 23 is the innermost layer and is directly in contact with the passing coolant. The texture layer 23 has a spiral microgroove structure and internal micropores. The micropores and microgrooves are connected, so that the passing coolant has a larger contact surface, further enhancing the heat exchange efficiency with the pipe wall. The flange 3 is integrally connected to the end of the pipe body 1, and has a connecting hole on it, which can be docked and connected with other pipe bodies 1. A sealing groove is also provided at the end face of the flange 3, and the sealing belt 4 can be clamped in the sealing groove to ensure the sealing of the connection and prevent coolant leakage. Among them, the contact area between the coolant and the pipe wall is increased through the internal polymer coating 2, especially the spiral microgroove structure and the internal micropores, so that the heat exchange is more sufficient and the cooling efficiency is effectively improved. The setting of the adhesive layer 21 and the hard layer 22 strengthens the strength of the inner wall of the pipe, increases durability, and extends the service life of the product. The hard layer 22 can also protect the adhesive layer 21 to a certain extent and reduce the erosion caused by direct contact with the fluid. The setting of the flange 3 and the sealing belt 4 maintains the sealing of the pipe connection and prevents leakage of the coolant, thereby improving the operation efficiency of the system. Through the setting of the flange 3, one pipe body 1 can be connected to multiple pipe bodies 1, which increases the scalability and flexibility of the system.

[0026] In a preferred embodiment, a plurality of annular stripe grooves are formed on the inner wall of the pipe body 1, and the adhesive layer 21 is coated on the inner wall of the pipe body 1 and fits with the inner wall of the stripe grooves. The adhesive layer 21 fits with the inner wall of the stripe grooves can increase the contact area with the pipe body 1, thereby improving the connection strength, making the polymer coating 2 and the pipe body 1 more tightly bonded and not easy to fall off. The existence of the stripe grooves provides more supporting points, making the adhesive layer 21 more evenly distributed on the inner wall of the pipe, improving the stability of the coating, and thus helping to extend the service life of the entire pipe system.

[0027] In a preferred embodiment, the hard layer 22 is made of polymer ceramic material and sprayed on the adhesive layer 21 to improve the strength of the polymer coating 2. During operation, the polymer ceramic material not only enhances the physical properties of the coating, but also increases the stability of the coating and the resistance to chemical corrosion. Due to the improvement of the overall strength of the coating, the service life of the polymer coating 2 can be extended, so that the maintenance frequency of related components is reduced.

[0028] In a preferred embodiment, the texture layer 23 is made of a high molecular polymer material and is sprayed on the hard layer 22. The combination of micropores and microgrooves opened inside provides a larger surface area for the fluid, improves the heat transfer effect, and achieves a filtering effect.

[0029] Specifically, the high molecular polymer material can provide a protective layer to prevent the hard layer 22 from being directly exposed to the environment, thereby reducing wear and corrosion. Since the texture layer 23 has a large number of micropores and microgroove structures, it can provide a larger surface area for the fluid, thereby more effectively conducting heat. This is very beneficial for applications that require efficient heat transfer, such as cooling systems, heat exchangers, etc. Moreover, the micropores and microgroove structures can also have a filtering effect. When the fluid passes through the texture layer, larger particles and impurities will be captured by the micropores and microgroove structures, thereby purifying the fluid.

[0030] In a preferred embodiment, a plurality of ball head connecting rods 5 are arranged in an annular array inside the end face sealing groove of the flange 3, the diameter of the ball head part of the ball head connecting rod 5 is larger than the rod body diameter of the ball head connecting rod 5, a plurality of snap-in grooves are arranged in an inner circumferential array of the sealing belt 4, the number of snap-in grooves is twice the number of the ball head connecting rods 5, and the sealing belt 4 is snap-in on the ball head connecting rod 5, and the annular distribution positions of the ball head connecting rods 5 at both ends of the pipe body 1 are equidistantly staggered, and the sealing belt 4 at the connection of the two pipe bodies 1 is sealed and connected with the flanges 3 on both sides. During operation, the equidistantly staggered ball head connecting rods 5 ensure the stability and symmetry of the connection of the pipe body 1, making the connection more stable, the combination of the sealing belt 4 and the flange 3, combined with the setting of the ball head and the snap-in groove, can form an efficient sealing system to prevent fluid leakage, and the setting of multiple ball head connecting rods 5 and the snap-in groove increases the redundancy of the system, and even if a certain part fails, the other parts can still work normally.

[0031] In a specific implementation manner: the inner wall of the pipe body 1 is coated with a polymer coating 2, and the polymer coating 2 is divided into an adhesive layer 21, a hard layer 22 and a texture layer 23. The adhesive layer 21 directly contacts the pipe body 1 and is connected thereto, and the hard layer 22 is connected to the adhesive layer to further fix and enhance the stability of the adhesive layer 21. The texture layer 23 is the innermost layer and is directly in contact with the passing coolant. The texture layer 23 has a spiral microgroove structure and internal micropores. The micropores and microgrooves are connected, so that the passing coolant has a larger contact surface, further enhancing the heat exchange efficiency with the pipe wall. The flange 3 is integrally connected to the end of the pipe body 1, and has a connecting hole on it, which can be docked and connected with other pipe bodies 1. A sealing groove is also provided at the end face of the flange 3, and the sealing belt 4 can be clamped in the sealing groove to ensure the sealing of the connection and prevent coolant leakage. Among them, the contact area between the coolant and the pipe wall is increased through the internal polymer coating 2, especially the spiral microgroove structure and the internal micropores, so that the heat exchange is more sufficient and the cooling efficiency is effectively improved. The setting of the adhesive layer 21 and the hard layer 22 strengthens the strength of the inner wall of the pipe, increases durability, and extends the service life of the product. The hard layer 22 can also protect the adhesive layer 21 to a certain extent and reduce the erosion caused by direct contact with the fluid. The setting of the flange 3 and the sealing belt 4 maintains the sealing of the pipe connection and prevents leakage of the coolant, thereby improving the operation efficiency of the system. Through the setting of the flange 3, one pipe body 1 can be connected to multiple pipe bodies 1, which increases the scalability and flexibility of the system.
