Abstract
Description
Technical Field
[0001] The invention relates to the technical field of heat pipes, and in particular to a wire mesh liquid wick assembly and a forming method thereof, and a heat pipe comprising the same and an assembling method thereof. Background Art
[0002] As an efficient heat transfer element, heat pipes play an important role in many industrial fields. During the evaporation and condensation process of heat pipes, the wick is a key component that promotes the reflux of working liquid and maintains the efficient operation of heat pipes.
[0003] Metal mesh is considered to be an ideal material for making wicks due to its excellent thermal conductivity and good capillary effect. However, in the actual manufacturing process, the hardness of the mesh is relatively high and it is not easy to bend and shape. When rolled into a cylindrical shape, delicate operation is required to maintain the shape and tension of the mesh, and it is not easy to form during rolling. When the rolled mesh wick is inserted into the tube, since the inner diameter of the tube is comparable to the outer diameter of the mesh, the existing mesh wicks often produce friction during assembly, resulting in the mesh being squeezed and deformed, failing to reach the designed length and failing to cover the entire interior of the heat pipe. This deformation destroys the structural integrity of the wick, thereby affecting the heat transfer performance and service life of the heat pipe. In addition, during the process of inserting the mesh wick, the mesh wick is prone to deformation or bending, which makes it inconvenient for operators to complete assembly. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art that the wire mesh wick is not easy to form during rolling, is easily deformed during assembly, and is difficult to assemble, and to provide a wire mesh wick assembly and a forming method thereof, and a heat pipe comprising the same and an assembly method thereof.
[0005] The present invention solves the above technical problems through the following technical solutions:
[0006] A method for forming a wire mesh wick assembly, the method comprising:
[0007] Cutting the wire mesh and preparing mandrels, the mandrels including at least a first mandrel;
[0008] The wire mesh is evenly wound and attached to the outer side of the first core rod, and at least one layer is wound along the first core rod to form a cylindrical wire mesh liquid absorbent core;
[0009] A plurality of fixing belts are used to surround the wire mesh absorbent core, wherein the plurality of fixing belts are arranged at intervals along the length direction of the wire mesh absorbent core, and the wire mesh absorbent core is fixed by the fixing belts to maintain a cylindrical shape;
[0010] The first core rod is separated from the wire mesh absorbent core fixed by the fixing belt, and the wire mesh absorbent core equipped with the fixing belt is used as a wire mesh absorbent core assembly.
[0011] In this solution, the wire mesh is rolled with the help of a mandrel, so that the operator can use the mandrel to more evenly wind the wire mesh into a cylindrical shape. After the rolling is completed, a fixing belt is used to surround the cylindrical ribbon to fix the wire mesh. This solution arranges fixing belts at intervals along the length direction of the wire mesh absorbent core to maintain the tension and shape of the wire mesh absorbent core after rolling, prevents it from deforming during subsequent processing and assembly, and provides a wire mesh absorbent core assembly that maintains structural rigidity and is easy to assemble later.
[0012] Preferably, the core rod further comprises a second core rod, after the wire mesh is cut, and the tube shell and the core rod are prepared, the core rod comprises at least the first core rod; and before the wire mesh is uniformly wound and attached to the outside of the first core rod, and at least one layer is wound along the first core rod to form a cylindrical wire mesh absorbent core; the forming method of the wire mesh absorbent core assembly further comprises the steps of:
[0013] Pre-winding the wire mesh on the second mandrel through auxiliary padding so that the wire mesh is evenly attached to the outer side of the second mandrel and forms a cylindrical shape;
[0014] separating the second mandrel from the wire mesh and forming a pre-rolled wire mesh;
[0015] And, in the step of uniformly winding the wire mesh and attaching it to the outer side of the first core rod, and winding at least one layer along the first core rod to form a cylindrical wire mesh absorbent core, the wire mesh is a pre-rolled wire mesh.
[0016] In this solution, the screen is pre-rolled before rolling to further ensure the accuracy and stability of the screen shape, so that the screen is easy to form during the subsequent secondary rolling, and the rebound during the screen rolling process is reduced. The screen is rolled twice through the core rod, the first time is the preliminary shaping, and the second time is the final shaping. Thus, the shape stability and structural integrity of the screen absorbent core are ensured through the double rolling process, the durability and reliability of the product are improved, and it is convenient for the subsequent installation of the fixing belt and the fixing of the screen. In this solution, auxiliary pads are used during rolling. The operator indirectly rolls and bends the screen through the auxiliary pads during rolling, thereby reducing friction during the screen rolling process, making the screen more evenly stressed, reducing deformation during the screen rolling process, and assisting the operator in rolling, so as to improve the efficiency and effect of rolling and increase the yield rate of the screen.

[0021] In this solution, the auxiliary padding is cut so that the size, length and width of the auxiliary padding match the wire mesh and the second core rod. In this solution, the edge of the auxiliary padding is glued and connected to the outside of the second core rod, and the wire mesh is initially rolled and shaped by combining the core rod and auxiliary paper. This process improves the accuracy of wire mesh forming. Compared with the traditional manual rolling method, the method of this solution indirectly rolls and bends the wire mesh through the auxiliary padding, reduces the friction during the wire mesh rolling process, makes the wire mesh more evenly stressed, reduces the deformation during the wire mesh rolling process, assists the operator in rolling, improves the uniformity and consistency of the wire mesh absorbent core, thereby improving the efficiency and effect of rolling and increasing the yield of the wire mesh.
[0022] Preferably, the step of separating the second mandrel from the wire mesh and forming a pre-rolled wire mesh comprises:
[0023] The second core rod, the wire mesh and the auxiliary pad are shaken in the vertical direction, so that the wire mesh falls off from between the second core rod and the auxiliary pad in the vertical direction.

[0030] Preferably, the wire mesh wick in the wire mesh wick assembly is used to be installed in a tube shell of the heat pipe, and the length of the tube shell is 0.2 meters to 13 meters;

The tube shell material is selected according to the compatibility of the working medium of the heat pipe, and the materials that can be used include copper, stainless steel, and nickel-based alloys. The material used for the wire mesh can be selected from various materials according to its working temperature. For heat pipes working at medium and high temperatures, the wire mesh material is preferably stainless steel.

[0061] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.
[0062] like Figure 1 As shown, this embodiment provides a method for forming a wire mesh absorbent core assembly 1, and the method for forming the wire mesh absorbent core assembly 1 includes:
[0063] S100: cutting the wire mesh and preparing the mandrel 2, the mandrel 2 including at least a first mandrel;
[0064] S300: The wire mesh is uniformly rolled up and attached to the outer side of the first core rod, and at least one layer is wound along the first core rod to form a cylindrical wire mesh liquid absorbent core 11;
[0065] S400: using a plurality of fixing belts 12 to surround the wire mesh absorbent core 11, the plurality of fixing belts 12 are arranged at intervals along the length direction of the wire mesh absorbent core 11, and the wire mesh absorbent core 11 is fixed by the fixing belts 12 to maintain a cylindrical shape;
[0066] S500: Separate the first core rod from the wire mesh absorbent core 11 fixed by the fixing belt 12, and use the wire mesh absorbent core 11 equipped with the fixing belt 12 as the wire mesh absorbent core assembly 1.
[0067] In this embodiment, the core rod 2 assists the rolling of the wire mesh, so that the operator can use the core rod 2 to more evenly wind the wire mesh into a cylindrical shape. After the rolling is completed, a fixing belt 12 is used to surround the cylindrical ribbon to fix the wire mesh. By arranging the fixing belts 12 at intervals along the length direction of the wire mesh absorbent core 11, the tension and shape of the wire mesh absorbent core 11 after rolling are maintained to prevent deformation during subsequent processing and assembly, thereby providing a wire mesh absorbent core assembly that maintains structural rigidity and is convenient for subsequent assembly.
[0068] As a preferred embodiment, after the formation and production of the wire mesh absorbent core assembly 1 is completed, the steps further include:
[0069] S600: Perform a final inspection to ensure that the shape, size and number of layers of the screen absorbent core 11 meet the design requirements. Check the screen for damage, wrinkles or uneven areas, and make necessary adjustments.
[0070] The wire mesh wick 11 in the wire mesh wick assembly 1 is used to be installed in the tube shell 3 of the heat pipe.
[0071] As a preferred embodiment of the fixing belt 12, the fixing belt 12 in this embodiment is a rubber band. In other embodiments, the fixing belt 12 can be made of other materials including rubber bands, iron wires, thin ropes, and plastic tie bands as needed. Among them, the spacing between multiple fixing belts 12 is 5-10cm. Those skilled in the art can determine the specific number of fixing belts 12 and the appropriate spacing between fixing belts 12 according to the length of the wire mesh wick 11. As a preferred embodiment, in the above step S100, the core rod 2 also includes a second core rod. After the above step S100; and before the above step S300, the forming method of the wire mesh wick assembly 1 also includes the steps of:
[0072] S210: pre-winding the wire mesh on the second mandrel through an auxiliary pad (not shown in the figure) so that the wire mesh is evenly attached to the outer side of the second mandrel and forms a cylindrical shape;
[0073] S220: separating the second mandrel from the wire mesh to form a pre-rolled wire mesh;
[0074] Furthermore, in the above step S300, the wire mesh is a pre-rolled wire mesh.
[0075] By pre-rolling the wire mesh before rolling, the accuracy and stability of the wire mesh shape can be further ensured, the wire mesh can be easily formed during the subsequent secondary rolling, the rebound during the wire mesh rolling process can be reduced, and the subsequent installation of the fixing belt 12 and the fixation of the wire mesh can be facilitated; by using auxiliary padding during rolling, the operator can indirectly roll, press and bend the wire mesh through the auxiliary padding during rolling, thereby reducing friction during the wire mesh rolling process, making the wire mesh more evenly stressed, reducing deformation during the wire mesh rolling process, and assisting the operator in rolling, so as to improve the efficiency and effect of rolling and increase the yield of the wire mesh.
[0076] Wherein, step S210 further includes:
[0077] S211: Prepare and cut auxiliary padding;
[0078] S212: bonding the edge of the auxiliary gasket to the outer side of the second core rod;
[0079] S213: placing the wire mesh between the second core rod and the auxiliary padding material, and rolling the wire mesh and the auxiliary padding material around the second core rod so that the wire mesh and the auxiliary padding material are evenly attached to the outer side of the second core rod and form a cylindrical shape.
[0080] In this embodiment, the auxiliary pad is cut so that the size, length and width of the auxiliary pad match the wire mesh and the second core rod. The method of this embodiment pastes and connects the edge of the auxiliary pad to the outside of the second core rod, combines the size cutting of the auxiliary pad and aligning the wire mesh and the auxiliary pad, so that it is convenient for the operator to align the wire mesh with the auxiliary pad during the process of rolling the wire mesh, so as to maintain the winding alignment of the wire mesh and adjust the deviation generated during the rolling process in time, thereby increasing the accuracy of the wire mesh shape. By indirectly rolling, pressing and bending the wire mesh with the auxiliary pad, the friction during the wire mesh rolling process is reduced, the wire mesh is subjected to more uniform force, and the deformation during the wire mesh rolling process is reduced, and the operator is assisted in the rolling process to improve the efficiency and effect of the rolling and increase the yield rate of the wire mesh.
[0081] In this embodiment, the auxiliary padding is cut so that the size, length and width of the auxiliary padding match the screen and the second core rod. The method of this embodiment pastes the edge of the auxiliary padding to the outside of the second core rod, and uses the method of combining the core rod 2 with the auxiliary paper to perform preliminary rolling and shaping of the screen. This process improves the accuracy of screen forming. Compared with the traditional manual rolling method, this method indirectly rolls and bends the screen through the auxiliary padding, reduces the friction of the screen rolling process, makes the screen more evenly stressed, reduces the deformation of the screen rolling process, assists the operator in rolling, improves the uniformity and consistency of the screen absorbent core 11, thereby improving the efficiency and effect of rolling and increasing the yield rate of the screen.
[0082] As an implementation mode, a transparent tape or adhesive may be used to connect the edge of the auxiliary gasket to the outer side of the second core rod by gluing. In other implementation modes, a gluing method or no gluing method may be selected as required.
[0083] As an implementation manner, the above step S220 further includes:
[0084] S221: shaking the second core rod, the wire mesh and the auxiliary pad in the vertical direction, so that the wire mesh falls off from between the second core rod and the auxiliary pad in the vertical direction.
[0085] As an embodiment of the auxiliary padding material, the material of the auxiliary padding material includes any one of coated paper, synthetic paper, and matte paper. In other embodiments, those skilled in the art can select other materials as needed.
[0086] As an implementation manner, step S100 further includes:
[0087] S101: determining the required size of the wire mesh according to the predetermined length and inner diameter of the tube shell 3 of the heat pipe and the number of layers of the wire mesh liquid wick 11, and cutting the wire mesh to obtain a wire mesh of a corresponding size;
[0088] S102: preparing a core rod 2 according to a predetermined length and inner diameter of the tube shell 3 of the heat pipe, wherein the diameter of the core rod 2 is smaller than the inner diameter of the tube shell 3, wherein the core rod 2 includes a first core rod and a second core rod.
[0089] The size of the required wire mesh is determined according to the predetermined length, inner diameter and number of layers of the wire mesh wick 11 of the tube shell 3, and the wire mesh of the corresponding size is cut to make the wire mesh meet the requirements, which is convenient for rolling the wire mesh wick 11; the core rod 2 is prepared according to the size of the tube shell 3, so that the core rod 2 cooperates with the wire mesh to assist in rolling the wire mesh to form a wire mesh wick 11 of a suitable size, and the first core rod and the second core rod are prepared for standby, which is convenient for multiple rolling. The diameter of the core rod 2 is 2 to 10 mm smaller than the inner diameter of the tube shell 3, so that the rolled wire mesh can be inserted into the heat pipe during assembly.
[0090] In the specific implementation process, those skilled in the art may adjust the order of S101, S102 and S211 as needed, or perform the above three steps simultaneously. In other embodiments, those skilled in the art may design the diameter of the mandrel 2 as needed.
[0091] As a preferred embodiment, the length of the tube shell 3 is preferably within 3 meters; the number of layers of the wire mesh winding of the wire mesh liquid wick 11 is preferably 2 to 3 layers; the mesh number of the wire mesh is within 150 meshes, and the wire mesh within 150 meshes has a thicker wire diameter, higher hardness, and greater tension; the mesh number of the wire mesh used in the wire mesh liquid wick assembly 1 is the same. Among them, the material of the tube shell 3 is selected according to the compatibility of the working medium of the heat pipe, and the materials that can be used include copper, stainless steel, and nickel-based alloys. The material used for the wire mesh can be selected from various materials according to its working temperature. For heat pipes working at medium and high temperatures, the wire mesh material is preferably stainless steel.
[0092] In the specific implementation process, those skilled in the art can determine the length of the tube shell 3, the number of winding layers, material, mesh number of the wire mesh, and the material of the tube shell 3 and other process parameters or material selection according to actual needs.
[0093] like Figure 4 and Figure 5 As shown, this embodiment further provides a wire mesh absorbent core assembly 1, the wire mesh absorbent core assembly 1 comprises a wire mesh absorbent core 11 and a fixing belt 12, and the wire mesh absorbent core assembly 1 is manufactured by the forming method of the wire mesh absorbent core assembly 1 as described above.
[0094] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, this embodiment also provides a method for assembling a heat pipe, the heat pipe comprises a tube shell 3 and a wire mesh wick 11 in a wire mesh wick assembly 1, the wire mesh wick assembly 1 is made by the forming method of the wire mesh wick assembly 1 as described above;
[0095] The assembly method comprises the following steps:
[0096] S1: prepare tube shell 3;
[0097] S2: align one end of the wire mesh wick assembly 1 with the inlet of the tube shell 3, and gradually insert the wire mesh wick assembly 1 into the tube shell 3 along the length direction of the tube shell 3;
[0098] S3: After partially inserting the wire mesh wick assembly 1, before one of the fixing belts 12 of the tube shell 3 is inserted into the tube shell 3 along with the wire mesh wick assembly 1, remove a fixing belt 12 closest to the entrance of the tube shell 3;
[0099] S4: Continue to insert the wire mesh wick assembly 1 into the tube shell 3;
[0100] S5: Repeat S3-S4 until all the fixing tapes 12 are removed and the entire wire mesh wick 11 is completely inserted into the tube shell 3;
[0101] S6: Check the wire mesh wick 11 to ensure that the wire mesh wick 11 is evenly distributed in the entire tube shell 3, and the surface of the wire mesh wick 11 has no obvious ripples, wrinkles or deviations;
[0102] S7: After the assembly is completed, the tube shell 3 is sealed and tested to ensure that its performance and reliability meet the requirements.
[0103] In this embodiment, the tube shell 3 is prepared first to ensure that the interior of the heat pipe tube shell 3 is clean and free of foreign matter, and that the inner diameter and length of the tube shell 3 meet the design requirements. Figure 5 As shown, first align one end of the wire mesh wick assembly 1 with the inlet of the tube shell 3, and then Figure 6 As shown, the wire mesh absorbent core assembly 1 is inserted into the wire mesh absorbent core assembly 1 in sections, and the fixed tapes 12 distributed at intervals are removed in sections until the wire mesh absorbent core assembly 1 is inserted into the wire mesh absorbent core assembly 1 in sections. Figure 7 As shown, the entire wire mesh wick 11 is completely inserted into the tube shell 3. During the assembly process, the tension and shape of the wire mesh are maintained by the fixing belt 12, which increases the overall structural rigidity and reduces the deformation of the wire mesh wick 11 caused by the friction of the tube shell 3 during the insertion process. In this embodiment, the original whole section of the assembly is disassembled by removing the fixing belt 12 in sections, which reduces the difficulty of the assembly process and the stability and accuracy requirements for the operator, and reduces the friction deformation and damage risk of the heat pipe wire mesh wick 11 during the assembly process.
[0104] After the wire mesh wick 11 is fully inserted, as a preferred embodiment, a final inspection can be performed as needed to ensure that the wire mesh wick 11 is evenly distributed throughout the tube shell 3 without obvious ripples, wrinkles or offsets. The two ends of the heat pipe tube shell 3 are then closed and air tightness and integrity testing is performed. This includes leak testing and thermal cycling testing of the heat pipe to verify the overall performance and reliability of the heat pipe.
[0105] A heat pipe is manufactured by the above heat pipe assembly method.
[0106] As a specific implementation method, Figure 3 As shown, the present invention also discloses a method for forming and assembling a wire mesh wick 11 and its application, that is, a heat pipe including the wire mesh wick 11 and a method for assembling the heat pipe. The process from forming the wire mesh wick 11 to assembling the heat pipe is as shown in FIG. Figure 3 As shown, the following steps are included in sequence:
[0107] (1) Cutting the wire mesh: Use precision cutting tools to cut the wire mesh of appropriate size according to the length, inner diameter and number of layers of the required wire mesh wick 11 of the heat pipe shell 3. For example, if the heat pipe shell 3 is 1 meter long and has an inner diameter of 26 mm, and 3 layers of wire mesh are required, the length of the cut wire mesh should be slightly less than 1 meter, and the width should be such that the total diameter after the 3 layers are stacked is slightly less than 26 mm.
[0108] (2) Fixing auxiliary materials: Align one edge of the cut screen with an auxiliary pad of appropriate size and fix it with tape. As an implementation method of the auxiliary pad, the auxiliary pad is paper, which helps the screen to remain flat during the rolling process and be pulled out in the subsequent steps.
[0109] (3) Preliminary rolling: Use a second mandrel with a diameter of 16 mm to roll the screen around the mandrel 2 for preliminary shaping. During the rolling process, it is necessary to apply force evenly to ensure that the screen fits tightly to the mandrel 2 to form a uniform cylindrical shape.
[0110] (4) Pull out the auxiliary paper: After the screen is initially shaped, carefully pull out the auxiliary paper. This step requires careful operation to avoid deformation of the screen when pulling out the paper.
[0111] (5) Secondary rolling: Use the first mandrel to roll the initially shaped screen for the final shape. This step further ensures the accuracy and stability of the screen shape.
[0112] (6) Fixing the wire mesh: Use rubber bands and thin ropes as fixing belts 12 and fix them at appropriate distances (for example, every 5 cm) on the wire mesh to enhance the structural stability of the wire mesh absorbent core 11.
[0113] (7) Final inspection: Ensure that the shape, size and number of layers of the wire mesh wick 11 meet the design requirements. Check the wire mesh for damage, wrinkles or uneven areas, and make necessary adjustments.
[0114] Through the above steps, we can obtain a wire mesh wick 11 with a stable structure and precise shape, and the wick can be directly used for assembling the heat pipe.
[0115] Those skilled in the art can adjust the material, mesh number or number of layers of the wire mesh to adapt to different heat pipe designs and application requirements. For example, a wire mesh made of 304 stainless steel or 316L stainless steel can be selected, the mesh number of the wire mesh can be 30 mesh, 50 mesh, 150 mesh or 400 mesh, and the number of layers can be single layer or multi-layer (such as 3 layers). In addition, the outer diameter of the core rod 2 and the spacing distance of the fixed wire mesh can also be adjusted according to actual needs to optimize the performance and adaptability of the wire mesh liquid absorbent core 11.
