Description

Technical Field

[0001] This application relates to the field of radiator technology, and in particular to an impact-resistant heat dissipation device. Background Technology

[0002] During vehicle operation, the underside of the vehicle is often impacted by objects such as gravel. Furthermore, since the vehicle's radiator is usually located in the chassis, flying gravel can easily puncture the radiator's cooling pipes, causing coolant leakage.

[0003] To solve the above problems, the traditional solution is to install a stone guard on one side of the radiator. However, installing a stone guard not only takes up more vehicle assembly space, but also has a higher manufacturing cost, which is not conducive to reducing vehicle costs. Utility Model Content

[0004] Therefore, it is necessary to provide an impact-resistant heat dissipation device to solve the problems of large assembly space and high cost required by existing impact-resistant cooling pipe solutions.

[0005] The impact-resistant heat dissipation device provided in this application includes a first manifold, a second manifold, and a distribution pipe. Multiple distribution pipes are arranged at intervals. One end of each distribution pipe is connected to the first manifold, and the other end is connected to the second manifold. The two end faces formed by the parallel arrangement of multiple distribution pipes are defined as the front end face and the rear end face of the impact-resistant heat dissipation device. One or both of the ends of each distribution pipe near the front end face and the end near the rear end face are provided with an impact-resistant structure. The impact-resistant structure is formed by bending and stacking the walls of the distribution pipes.

[0006] In one embodiment, the sidewalls of the dispensing tube, positioned opposite each other along a predetermined height, are defined as a first sidewall and a second sidewall. The first sidewall is bent toward the direction closer to the second sidewall to form a first impact-resistant layer, and the second sidewall is bent toward the direction closer to the first sidewall to form a second impact-resistant layer. The first and second impact-resistant layers are stacked along a predetermined thickness direction to form an impact-resistant structure. The end face of the first impact-resistant layer facing the second impact-resistant layer is defined as the first end face, and the end face of the second impact-resistant layer facing the first impact-resistant layer is defined as the second end face. The first end face is attached to and welded to the second end face.

[0007] In one embodiment, a filler gap is provided between the first impact-resistant layer and the second impact-resistant layer. The filler gap is used to fill the gap with solder so that the first impact-resistant layer is brazed to the second impact-resistant layer. The inner wall of the filler gap has a welding surface, and the surface roughness Ra of the welding surface satisfies the condition 1μm≤Ra≤50μm.

[0008] In one embodiment, the thickness C of the first impact-resistant layer satisfies 0.05mm≤C≤0.5mm; and / or, the thickness D of the second impact-resistant layer satisfies 0.05mm≤D≤0.5mm.

[0009] In one embodiment, the sidewalls of the dispensing tube arranged opposite each other along a preset height direction are defined as a third sidewall and a fourth sidewall. The third sidewall is bent toward the direction closer to the fourth sidewall to form a first bent segment. The end of the first bent segment away from the third sidewall is bent toward the direction closer to the third sidewall to form a second bent segment. The fourth sidewall is bent toward the direction closer to the third sidewall to form a third bent segment. The end of the third bent segment away from the fourth sidewall is bent toward the direction closer to the fourth sidewall to form a fourth bent segment. The connection between the first bent segment and the second bent segment is brazed to the connection between the third bent segment and the fourth bent segment. The first bent segment, the second bent segment, the third bent segment, and the fourth bent segment constitute an impact-resistant structure.

[0010] In one embodiment, the sidewalls of the dispensing tube arranged opposite each other along a preset height direction are defined as a fifth sidewall and a sixth sidewall. The fifth sidewall is bent toward the direction close to the sixth sidewall to form a fifth bend segment. The end of the fifth bend segment away from the fifth sidewall is bent toward the direction close to the fifth sidewall to form a sixth bend segment. The connection between the fifth bend segment and the sixth bend segment is brazed to the sixth sidewall. The fifth bend segment and the sixth bend segment constitute an impact-resistant structure.

[0011] In one embodiment, the sidewalls of the liquid distribution tube arranged opposite each other along a preset height direction are defined as the seventh sidewall and the eighth sidewall. One or both of the seventh sidewall and the eighth sidewall are continuously bent and stacked along a preset thickness direction or a preset height direction to form an impact-resistant structure. The seventh sidewall, the impact-resistant structure and the eighth sidewall are integrally formed.

[0012] In one embodiment, the sidewalls of the dispensing tube arranged opposite each other along a preset height direction are defined as a ninth sidewall and a tenth sidewall. The ninth sidewall is bent toward the direction close to the tenth sidewall to form a seventh bend segment. The end of the seventh bend segment away from the ninth sidewall extends toward the direction away from the dispensing tube to form an eighth bend segment. The tenth sidewall is bent toward the direction close to the ninth sidewall to form a ninth bend segment. The end of the ninth bend segment away from the tenth sidewall extends toward the direction away from the dispensing tube to form a tenth bend segment. The eighth bend segment and the tenth bend segment are brazed to form an impact-resistant structure.

[0013] In one embodiment, a filler groove is provided between adjacent bent walls of the impact-resistant structure. The filler groove is used to fill the filler with solder so that the adjacent bent walls of the impact-resistant structure are brazed and fixed.

[0014] In one embodiment, there are multiple packing grooves, each packing groove extends along a preset width direction, and adjacent packing grooves are spaced apart along a preset height direction.

[0015] In one embodiment, a partition is provided inside the separator to divide the inner cavity of the separator into a first cavity and a second cavity arranged in parallel. The partition is formed by bending one side wall of the separator, and the partition and the other side wall of the separator are welded and fixed.

[0016] Compared with existing technologies, the impact-resistant heat dissipation device provided in this application directly utilizes the structural modification of the end of the distributor to form a protective layer, saving the space occupied by the protective mesh while maintaining the same impact resistance, and simplifying the assembly process of the impact-resistant heat dissipation device. Furthermore, the bending and stacking process of the distributor can be carried out simultaneously with the conventional brazing process, requiring no additional processing equipment. In summary, this solution eliminates the need for additional protective components, significantly reducing material costs and space requirements, and is suitable for compact vehicle chassis installation environments.

Detailed Implementation

[0034] Please see Figures 1-15The impact-resistant heat dissipation device is defined to include a preset height direction, a preset width direction, and a preset thickness direction, which are represented by X, Y, and Z in the figure, respectively. Here, X represents the preset height direction, Y represents the preset width direction, and Z represents the preset thickness direction.

[0035] In one embodiment, such as Figure 1 As shown, the impact-resistant heat dissipation device includes a first manifold 100, a second manifold 200, a liquid distribution pipe 300, and heat dissipation fins (not shown). The first manifold 100 and the second manifold 200 are arranged at intervals along a preset width direction and extend along a preset height direction respectively. Multiple liquid distribution pipes 300 are arranged at intervals along a preset height direction. Each liquid distribution pipe 300 is connected to the first manifold 100 at one end and to the second manifold 200 at the other end. Coolant is diverted from the first manifold 100 to each liquid distribution pipe 300 and then converges from each liquid distribution pipe 300 to the second manifold 200. The coolant in the second manifold 200 is cooled by components such as a compressor (not shown) and then re-enters the first manifold 100, thereby completing the heat dissipation cycle of the coolant. Heat dissipation fins are correspondingly arranged at the intervals between adjacent liquid distribution pipes 300 so that the heat in the liquid distribution pipes 300 can be transferred to the external space (which can be an air-cooled atmospheric environment or a liquid-cooled coolant environment) through the heat dissipation fins.

[0036] The impact-resistant heat dissipation device is defined as having two end faces formed by multiple liquid distribution pipes 300 arranged in parallel, namely the front end face 510 and the rear end face (not shown in the figure). The front end face 510 and the rear end face refer to the two exposed end faces formed when the array of liquid distribution pipes 300 is arranged in parallel. Each dispensing tube 300 has an impact-resistant structure 600 at one end near the front end face 510, or each dispensing tube 300 has an impact-resistant structure 600 at one end near the rear end face, or each dispensing tube 300 has an impact-resistant structure 600 at both ends near the front end face 510 and the rear end face. That is, the dispensing tube 300 has an impact-resistant structure 600 at one or both ends along a preset thickness direction. Furthermore, the impact-resistant structure 600 is formed by bending and stacking the wall surface of the dispensing tube 300. That is, the impact-resistant structure 600 and the dispensing tube 300 are integrally formed. Specifically, the wall surface of the dispensing tube 300 is stamped and bent to form a multi-layer stacked impact-resistant structure 600. The bending direction can be determined by mold positioning so that the impact-resistant structure 600 is concentrated in the exposed area most susceptible to external impact.

[0037] It should be noted that the preset height direction, preset width direction, and preset thickness direction are mutually perpendicular or approximately perpendicular.

[0038] Specifically, the liquid distribution tube 300 can be made of ductile metal tubing through an extrusion molding process, and its wall thickness can be adjusted according to fluid pressure and impact resistance requirements. While maintaining conventional heat dissipation function, the liquid distribution tube 300 forms an impact-resistant structure 600 through end structural deformation. The liquid distribution tube 300 can be a flat tube, square tube, or round tube, etc.

[0039] The impact-resistant structure 600 refers to a dense area formed by multiple bends and stacking of the pipe wall of the distributor 300. Specifically, a continuous bending process can be used to form multiple overlapping metal layers on the pipe wall, utilizing the plastic deformation of the material itself to absorb impact energy. This structure significantly improves the mechanical strength of the end region of the distributor 300 without adding any additional components.

[0040] Specifically, in one embodiment, both the liquid distribution pipe 300 and the impact-resistant structure 600 are aluminum alloy parts. Specifically, the aluminum plate is processed by a stamping machine and a bending machine to form the liquid distribution pipe 300 with the impact-resistant structure 600.

[0041] However, this is not the only embodiment. In other embodiments, the liquid distribution tube 300 and the impact-resistant structure 600 may also be made of stainless steel or copper alloy, etc., which will not be listed here.

[0042] Specifically, at the end of the distributor pipe 300 near the front face 510 or the rear face, the originally straight pipe wall is continuously bent longitudinally, forming a multi-layered stacked structure of the pipe wall material. During the bending process, by controlling the bending angle and stacking density, a buffer layer with gradient strength is formed in this area. When an external impact force acts on the front face 510 or the rear face, the impact energy is first absorbed and dispersed by the multi-layered bending structure, preventing the distributor pipe 300 from rupturing. Since the impact-resistant structure 600 is formed from the same material as the distributor pipe 300 itself, its connection strength with the main body is guaranteed, while not obstructing the normal flow of coolant within the pipe.

[0043] Compared to existing technologies, this solution directly utilizes the structural modification of the end of the distributor 300 to form a protective layer, saving space occupied by the protective mesh while maintaining the same impact resistance, and simplifying the assembly process of the impact-resistant heat dissipation device. Furthermore, the bending and stacking process of the distributor 300 can be performed simultaneously with conventional brazing, requiring no additional processing equipment. In summary, this solution eliminates the need for additional protective components, significantly reducing material costs and space requirements, making it suitable for compact vehicle chassis installation environments.

[0044] In one embodiment, such as Figure 2 as well as Figures 4-15As shown, a partition 410 is provided inside the liquid distribution tube 300 to divide the inner cavity 420 of the liquid distribution tube 300 into a first cavity 421 and a second cavity 422 arranged in parallel. The partition 410 is formed by bending one side wall of the liquid distribution tube 300, and the partition 410 and the other side wall of the liquid distribution tube 300 are welded and fixed.

[0045] Specifically, such as Figure 2 As shown, one side wall of the liquid separator 300 can be continuously bent to form an approximately U-shaped baffle 410. The two ends of the opening of the U-shaped baffle 410 are integrally formed with the side wall of the liquid separator 300, and the bottom of the U-shaped baffle 410 is welded to the side wall of the other side of the liquid separator 300 (brazing or ordinary flame welding).

[0046] Of course, such as Figure 9 As shown, another option is that after one side wall of the liquid separator 300 is cut off in the middle, the side walls at both ends of the end face are bent toward the adjacent side wall of the liquid separator 300 and welded thereto.

[0047] With this configuration, the partition 410 inside the liquid distribution tube 300 and the side wall of the liquid distribution tube 300 itself are integrally formed. On the one hand, this can reduce the processing difficulty of the partition 410, and on the other hand, it can improve the connection strength and sealing performance between the partition 410 and the liquid distribution tube 300.

[0048] Example 1

[0049] In this embodiment, as Figures 2-6 As shown, the impact-resistant structure 600 is a double-layer sidewall structure. The sidewalls of the liquid distribution tube 300, which are arranged opposite each other along the preset height direction, are defined as a first sidewall 310 and a second sidewall 320. The first sidewall 310 is bent toward the direction close to the second sidewall 320 to form a first impact-resistant layer 610, and the second sidewall 320 is bent toward the direction close to the first sidewall 310 to form a second impact-resistant layer 620. The first impact-resistant layer 610 and the second impact-resistant layer 620 are stacked along the preset thickness direction to form the impact-resistant structure 600.

[0050] The first sidewall 310 and the second sidewall 320 refer to the two opposite sidewall surfaces of the liquid distribution pipe 300 in the preset height direction. Specifically, they can be achieved by forming a symmetrical structure through pipe bending. The symmetrical structure is beneficial for evenly dispersing impact stress. The first impact-resistant layer 610 and the second impact-resistant layer 620 refer to the composite structural layers formed by bending the sidewalls. Specifically, they can be achieved by stacking the sidewall materials using a progressive bending process. The stacked structure can absorb impact energy through material deformation.

[0051] Specifically, the first sidewall 310 and the second sidewall 320 of the distribution tube 300 are bent towards each other to form a first impact-resistant layer 610 and a second impact-resistant layer 620, respectively. When an external impact force is applied to the end of the distribution tube 300, the first impact-resistant layer 610 and the second impact-resistant layer 620 are pressed against each other at the overlapping contact surface, absorbing the impact energy through the plastic deformation of the metal material. The increased interlayer friction and contact area of ​​the stacked structure cause the impact kinetic energy to be converted into heat energy and dispersed.

[0052] Furthermore, in one embodiment, the thickness A of the first sidewall 310 satisfies 0.05mm≤A≤0.5mm, preferably A is 0.2mm. Similarly, the thickness B of the second sidewall 320 satisfies 0.05mm≤B≤0.5mm, preferably B is 0.2mm.

[0053] Correspondingly, the thickness C of the first impact-resistant layer 610 satisfies 0.05mm≤C≤0.5mm, preferably C is 0.2mm. Similarly, the thickness D of the second impact-resistant layer 620 satisfies 0.05mm≤D≤0.5mm, preferably D is 0.2mm.

[0054] This design achieves a balance between processing difficulty and structural strength.

[0055] In one embodiment, a filler gap (not shown) is provided between the first impact-resistant layer 610 and the second impact-resistant layer 620. Therefore, the overall thickness of the impact-resistant structure 600 is greater than the sum of the thickness of the first impact-resistant layer 610 and the thickness of the second impact-resistant layer 620. The filler gap is used to fill solder so that the first impact-resistant layer 610 is brazed to the second impact-resistant layer 620.

[0056] It should be noted that the filler gap refers to the void area formed when the first impact-resistant layer 610 and the second impact-resistant layer 620 are stacked. This gap can be achieved by controlling the dimensional tolerances of the bending and stacking. This gap allows the solder to fill evenly and penetrate through capillary action. The solder can be tin-based or silver-based brazing filler metal, which melts and wets the gap surface during heating to form a metallurgical bonding layer.

[0057] Specifically, the first sidewall 310 and the second sidewall 320 at the end of the distributor 300 are bent to form a first impact-resistant layer 610 and a second impact-resistant layer 620, respectively, with a predetermined gap maintained when they are stacked as a filler gap. Solder is applied or pre-placed into the gap, melting and flowing during heating to cover the welding surface of the inner wall of the gap. After the molten solder cools, it forms a brazed joint, creating a rigid connection between the impact-resistant layers while maintaining the integrity of the internal flow channels of the distributor 300. This structure solidifies the impact-resistant layers into a whole through solder filling and brazing processes, preventing a decrease in impact resistance due to interlayer loosening.

[0058] This design integrates impact resistance with heat dissipation by directly forming an impact-resistant layer at the end of the 300-inch distribution tube and filling it with solder. Compared to mechanical riveting or bolting, brazing eliminates the impact of assembly errors on interlayer gaps and prevents connection failure due to vibration.

[0059] Furthermore, in one embodiment, the inner wall of the filler gap is provided with a welding surface (not shown in the figure), that is, the two end faces of the first impact-resistant layer 610 and the second impact-resistant layer 620 are provided with welding surfaces, and the surface roughness Ra of the welding surface satisfies 1μm≤Ra≤50μm.

[0060] The welding surface refers to the area where the inner wall of the filler gap contacts the solder. Surface roughness can be controlled through sandblasting, chemical etching, or machining. Surface roughness Ra refers to the arithmetic mean deviation of the profile. This range ensures that the solder forms a uniform filling layer within the gap, avoiding insufficient solder adhesion due to excessively low roughness, and preventing gap blockage or solder flow obstruction due to excessively high roughness.

[0061] However, this is not the only possibility. In other embodiments, the inner wall of the packing gap may be a smooth inner wall.

[0062] In another embodiment, such as Figure 3 As shown, the end face of the first impact-resistant layer 610 facing the second impact-resistant layer 620 is defined as the first end face 611, and the end face of the second impact-resistant layer 620 facing the first impact-resistant layer 610 is defined as the second end face 621. The first end face 611 is attached to the second end face 621. That is, without considering assembly tolerances, the overall thickness of the impact-resistant structure 600 is equal to the sum of the thickness of the first impact-resistant layer 610 and the thickness of the second impact-resistant layer 620. One or both of the first end face 611 and the second end face 621 are provided with a filler groove 630. The filler groove 630 is used to fill solder so that the first impact-resistant layer 610 is brazed to the second impact-resistant layer 620.

[0063] The filler groove 630 refers to a groove structure provided on the first end face 611 or the second end face 621. Specifically, it can be formed into regularly arranged grooves on the end face by machining or stamping. The function of the filler groove 630 is to contain the solder and guide the solder to be evenly distributed during the brazing process, thereby improving the welding strength.

[0064] Specifically, at the overlapping contact end faces, by providing continuously extending filler grooves 630 on one or both sides, when the solder is filled into the groove, the molten solder can spread evenly along the length of the groove during heating, forming a continuous welding interface. This structure allows the first impact-resistant layer 610 and the second impact-resistant layer 620 to effectively disperse stress at the welded joint when subjected to external impact, avoiding cracking problems caused by local stress concentration.

[0065] It should be noted that this application includes multiple embodiments of the impact-resistant structure 600. In other embodiments, a filler groove 630 may also be provided between adjacent bent walls of the impact-resistant structure 600 to allow the adjacent bent walls of the impact-resistant structure 600 to be brazed and fixed.

[0066] Furthermore, in one embodiment, as Figure 3 As shown, there are multiple packing grooves 630, each packing groove 630 extends along a preset width direction, and adjacent packing grooves 630 are spaced apart along a preset height direction.

[0067] Specifically, the distribution pipe 300 forms a stacked impact-resistant structure 600 near its end by bending its sidewall. Laterally extending strip-shaped filler grooves 630 are provided on the stacked contact surface, and these grooves are arranged at equal intervals in the vertical direction. During brazing, molten solder preferentially fills the filler grooves 630, forming multiple transverse reinforcing ribs after cooling and solidification. The gaps between adjacent filler grooves 630 allow the solder to form continuous welds in the vertical direction, creating a crisscrossing weld network. This structure allows the impact energy to be dispersed and transferred through the transverse reinforcing ribs when subjected to gravel impacts, while the vertical welds effectively inhibit interlayer delamination.

[0068] In one embodiment, such as Figure 5 and Figure 6 As shown, the second impact-resistant layer 620 extends a certain distance along the inner side of the first sidewall 310 and is bent toward the second sidewall 320 and supported on the inner side of the second sidewall 320 to enhance the structural strength inside the liquid distribution tube 300.

[0069] Furthermore, in one embodiment, as Figure 6 As shown, the first impact-resistant layer 610 extends a certain distance along the outer surface of the second sidewall 320 and covers the outer surface of the second sidewall 320 to enhance the overall strength of the impact-resistant structure 600.

[0070] Example 2

[0071] In this embodiment, as Figure 7As shown, the sidewalls of the separator 300, positioned opposite each other along a preset height direction, are defined as a third sidewall 330 and a fourth sidewall 340. The third sidewall 330 is bent towards the fourth sidewall 340 to form a first bent segment 641. The end of the first bent segment 641 away from the third sidewall 330 continues to bend towards the third sidewall 330 to form a second bent segment 642. That is, the first bent segment 641 and the second bent segment 642 are continuous bent structures formed by the third sidewall 330, and the overall shape is approximately U-shaped. The fourth sidewall 340 is bent towards the third sidewall 330 to form a third bent segment 643. The end of the third bent segment 643 away from the fourth sidewall 340 continues to bend towards the fourth sidewall 340 to form a fourth bent segment 644. That is, the third bent segment 643 and the fourth bent segment 644 are continuous bent structures formed by the fourth sidewall 340, and the overall shape is also approximately U-shaped. The connection between the first bending segment 641 and the second bending segment 642 is brazed to the connection between the third bending segment 643 and the fourth bending segment 644. The first bending segment 641, the second bending segment 642, the third bending segment 643 and the fourth bending segment 644 constitute an impact-resistant structure 600. Thus, the overall shape of the impact-resistant structure 600 is similar to two back-to-back C-shaped structures connected together.

[0072] Specifically, the third sidewall 330 of the distributor 300 first bends inward to form the first bent section 641, and then bends back in the opposite direction to form the second bent section 642. Simultaneously, the fourth sidewall 340 bends to form the third bent section 643 and the fourth bent section 644. The ends of the two sets of bent sections are brazed together, creating a locally thickened area at the end of the distributor 300 composed of two layers of metal. When gravel impacts the end face of the distributor 300, the impact force is dispersed and absorbed by the multi-layered bending structure. Simultaneously, the brazed connection prevents separation or misalignment between the bent sections, thereby improving impact resistance within a limited space.

[0073] Furthermore, in one embodiment, the opposite sides of the first bending segment 641 and the second bending segment 642 are brazed together, and similarly, the opposite sides of the third bending segment 643 and the fourth bending segment 644 are brazed together.

[0074] Example 3

[0075] In this embodiment, as Figure 8As shown, the sidewalls of the separator 300, positioned opposite each other along a predetermined height, are defined as a fifth sidewall 350 and a sixth sidewall 360. The fifth sidewall 350 is bent towards the direction closer to the sixth sidewall 360 to form a fifth bent segment 651. The end of the fifth bent segment 651 away from the fifth sidewall 350 is further bent towards the direction closer to the fifth sidewall 350 to form a sixth bent segment 652. The connection between the fifth bent segment 651 and the sixth bent segment 652 is brazed to the sixth sidewall 360, and the fifth bent segment 651 and the sixth bent segment 652 constitute an impact-resistant structure 600.

[0076] The fifth bending segment 651 refers to the folded portion formed by bending the fifth sidewall 350 into the liquid distribution pipe 300. This can be achieved by continuously bending the metal sheet using a stamping process. Its function is to increase the local thickness through a layered structure to resist external impacts. The sixth bending segment 652 refers to the folded portion formed by further bending the end of the fifth bending segment 651 in the opposite direction. This can be formed using a secondary bending process. Its function is to create a closed cavity through the fold to improve resistance to deformation.

[0077] Specifically, the fifth sidewall 350 is first bent to a position close to the sixth sidewall 360 to form the fifth bent segment 651. Then, the end of the fifth bent segment 651 is bent again towards the fifth sidewall 350 to form the sixth bent segment 652, creating a multi-layered impact-resistant area between the fifth bent segment 651 and the sixth bent segment 652. The connection between the fifth bent segment 651 and the sixth bent segment 652 is fixed to the sixth sidewall 360 by brazing, making the impact-resistant structure 600 and the main body of the distribution pipe 300 an integrated structure. This design eliminates the need for additional external protective components; the layered structure formed by bending absorbs impact energy through metal deformation, while the brazing connection ensures the overall strength of the multi-layered structure.

[0078] Furthermore, in one embodiment, the fifth bend segment 651 and the sixth bend segment 652 are brazed together on opposite sides.

[0079] Example 4

[0080] In this embodiment, as Figures 9-13 As shown, the sidewalls of the liquid distribution tube 300 arranged opposite each other along the preset height direction are defined as the seventh sidewall 370 and the eighth sidewall 380. One or both of the seventh sidewall 370 and the eighth sidewall 380 are continuously bent and stacked along the preset thickness direction or the preset height direction to form the impact-resistant structure 600. The only difference between the two is the stacking direction. When stacked along the preset thickness direction, the bent section mainly extends along the preset height direction. When stacked along the preset height direction, the bent section mainly extends along the preset thickness direction. Furthermore, the seventh sidewall 370, the impact-resistant structure 600 and the eighth sidewall 380 are integrally formed.

[0081] It should be noted that adjacent bending sections can be fixed by brazing.

[0082] Continuous bending refers to the formation of a layered structure by bending metal sheets multiple times. Specifically, it can be achieved by continuous bending process using stamping dies. This process can form a multi-layered structure without cutting the material.

[0083] Among them, the one-piece molding structure refers to the impact-resistant structure 600 and the side wall of the liquid distribution pipe 300 being formed as a whole through a single processing flow. Specifically, it can be achieved by sheet metal stamping forming process, which can eliminate the structural fragility caused by welding seams.

[0084] The stacking direction is selected according to the preset thickness direction or height direction. Specifically, the stacking direction can be controlled by adjusting the bending angle. For example, when the preset thickness direction is the preset width direction, the bending trajectory will be perpendicular to the fluid channel axis.

[0085] Specifically, the metal sheets of the seventh sidewall 370 and the eighth sidewall 380 are continuously bent to form a wavy or stepped layered structure. When the end of the distributor 300 is impacted by gravel, the impact energy is gradually absorbed through the plastic deformation of the layered structure, while the multiple metal sheets support each other to form a rigid barrier. During the manufacturing process, the sidewalls of the distributor 300 are bent more than twice using a stamping die, so that the metal sheets form an interlocking layered shape in the width or height direction.

[0086] Specifically, such as Figure 9 and Figure 10 As shown, the shape of the impact-resistant structure 600 can be similar to the structure of Embodiment 2 or Embodiment 3. The difference is that in Embodiment 2 and Embodiment 3, the opposite sidewalls of the liquid distribution tube 300 are split structures at the impact-resistant structure 600, while in Embodiment 4, the opposite sidewalls of the liquid distribution tube 300 are integral structures at the impact-resistant structure 600.

[0087] In other embodiments, such as Figures 11-13 As shown, the shape of the impact-resistant structure 600 can also be composed of multiple parallel bent segments. It should be noted that the connection between adjacent bent segments has a certain curvature.

[0088] Example 5

[0089] In this embodiment, as Figure 14 and Figure 15As shown, the sidewalls of the separator 300, positioned opposite each other along a predetermined height, are defined as a ninth sidewall 390 and a tenth sidewall 400. The ninth sidewall 390 is bent towards the tenth sidewall 400 to form a seventh bend segment 661. The end of the seventh bend segment 661 away from the ninth sidewall 390 extends away from the separator 300 to form an eighth bend segment 662. The eighth bend segment 662 is parallel to the ninth sidewall 390. The tenth sidewall 400 is bent towards the ninth sidewall 390 to form a ninth bend segment 663. The end of the ninth bend segment 663 away from the tenth sidewall 400 extends away from the separator 300 to form a tenth bend segment 664. The tenth bend segment 664 is parallel to the tenth sidewall 400. Furthermore, the eighth bend segment 662 and the tenth bend segment 664 are brazed to form an impact-resistant structure 600.

[0090] The seventh bending segment 661 refers to the curved structure formed by bending from the ninth sidewall 390 to the tenth sidewall 400, and the eighth bending segment 662 is a flat plate segment extending outward from the end of the seventh bending segment 661. Together, they form an outwardly expanding protective layer. The ninth bending segment 663 and the tenth bending segment 664 are formed in the same manner on the tenth sidewall 400 and are arranged symmetrically with the eighth bending segment 662.

[0091] Specifically, when the gravel impacts the end of the separator 300, the impact-resistant structure 600 disperses the impact energy through the synergistic effect of multiple bending sections. Furthermore, the seventh bending section 661 and the ninth bending section 663 can serve as buffer layers to absorb the initial impact force through elastic deformation.

[0092] Furthermore, in one embodiment, as Figure 15 As shown, the tenth bending segment 664 continues to bend and wraps around the outer periphery of the eighth bending segment 662, so that the impact-resistant structure 600 forms a three-section structure.
