Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lithium battery accessory manufacturing technology, specifically relating to microchannel cleaning of lithium battery heat exchangers, and particularly to cleaning roller assembly and cleaning system for microchannels in lithium battery heat exchangers. Background Technology
[0002] In lithium-ion battery thermal management systems, microchannels serve as crucial heat exchange components, and their efficient heat conduction performance directly impacts the battery pack's temperature control stability and cycle life. Existing microchannels typically employ a flat, elongated strip structure to maximize heat exchange area within a limited space. However, during the manufacturing and packaging processes, processing debris, lubricating media, or oxidative contaminants can easily remain on their surfaces. Failure to thoroughly remove these contaminants can lead to decreased heat exchange efficiency, increased resistance to media flow, and even corrosion. Therefore, cleaning and impurity removal from the microchannel surface is essential to ensuring its stable performance.
[0003] In microchannel surface treatment processes, drying and secondary cleaning after cleaning are key steps to ensure surface cleanliness. Typically, a cleaning tube-type wiping brush is used to dry the metal surface and remove residues.
[0004] The existing cleaning cylinder adopts an integral installation structure, and its rotating shaft is rigidly connected to the drive device through bolt groups or snap-fit mechanisms. According to the experimental data of "Influence of Fiber Load on Scratch Rate in Microchannel Surface Treatment" published in the Journal of Metal Surface Engineering in 2022, when the fiber adsorbs metal dust ≥50μm, the scratch rate increases by 40%. At this time, the machine must be stopped and the cleaning cylinder must be disassembled for cleaning. The disassembly process requires workers to use special tools to operate on the locking parts one by one, and a single disassembly takes more than 15 minutes. In microchannel continuous processing production lines, such maintenance operations result in system downtime accounting for as much as 18% to 25%, which seriously restricts the overall production efficiency.
[0005] Therefore, how to solve the problem of the need for the cleaning cylinder to pause the microchannel cleaning system for a long time is a technical problem that urgently needs to be solved in this field.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0007] This disclosure provides at least one cleaning roller assembly and cleaning system for microchannels used in lithium battery heat exchangers, to solve the technical problem that cleaning the cleaning roller requires a long-term pause in the microchannel cleaning system.
[0008] In a first aspect, embodiments of this disclosure provide a cleaning roller assembly for a microchannel used in a lithium battery heat exchanger, comprising: a cleaning cylinder mounted on a support rod, wherein a cleaning fiber cleaning structure is provided on the surface of the cleaning cylinder and is mounted on one end of the support rod, and includes a movable ring with an inner diameter smaller than the outer diameter of the cleaning cylinder, wherein a rack is provided on the inner wall of the movable ring; wherein the movable ring is configured to move along the axial direction of the support rod so that the rack combs the fibers and squeezes the cleaning cylinder and the fiber surface.
[0009] In one optional embodiment, elastic bladders are provided on both sides of the moving ring, with their squeezing ends extending toward the center of the moving ring. The elastic bladders are adapted to move with the moving ring to squeeze the cleaning cylinder and the fiber surface, so that the sewage is discharged.
[0010] In one optional embodiment, a water storage cavity is provided inside the moving ring, which is connected to the elastic bladder. A plurality of spray holes are provided on the inner wall of the moving ring. The spray holes are arranged circumferentially along the inner wall of the moving ring and symmetrically arranged along the rack. The spray holes are conical and the diameter gradually increases from the inner wall of the moving ring towards the water storage cavity. When the elastic bladder squeezes the cleaning cylinder and the fiber surface, water in the water storage cavity flows out of the spray holes to clean the cleaning cylinder and the fiber surface.
[0011] In one alternative embodiment, the outer wall of the movable ring is provided with a water inlet, which is suitable for adding water into the water storage chamber.
[0012] In one optional embodiment, scraping rings are provided on both sides of the moving ring, with their squeezing ends extending toward the center of the moving ring. The rack moves with the moving ring to comb the fibers, causing the particles to fall between the two scraping rings.
[0013] In one optional embodiment, a dust collection trough is provided inside the moving ring, and two sets of long slots are provided on the inner wall of the moving ring, which are symmetrically arranged along the rack; and the width of the two sets of long slots gradually decreases from the inner wall of the moving ring towards the dust collection trough, wherein the particles that fall between the two scraping rings move with the moving ring and enter the dust collection trough from the long slots.
[0014] In one optional embodiment, the outer wall of the moving ring is provided with a ash discharge port.
[0015] Secondly, this disclosure also provides a lithium battery heat exchanger microchannel cleaning system, including: a conveying device adapted to convey a microchannel cleaning machine, which is disposed on one side of the conveying device; the cleaning machine includes a rotating assembly and a roller assembly, the roller assembly being disposed on the rotating assembly; the roller assembly includes a support rod, which is mounted on the rotating assembly by a locking member; a cleaning cylinder is fitted onto the support rod, and a cleaning fiber cleaning structure is provided on the surface of the cleaning cylinder, which is fitted onto one end of the support rod; the cleaning structure includes a movable ring, the inner diameter of which is smaller than the outer diameter of the cleaning cylinder; and a rack is provided on the inner wall of the movable ring; wherein the movable ring is configured to move along the axial direction of the support rod to cause the rack to comb the fibers and squeeze the cleaning cylinder and the fiber surface.
[0016] In one optional embodiment, elastic bladders are provided on both sides of the moving ring, with their squeezing ends extending towards the center of the moving ring. A water storage cavity is provided inside the moving ring, which communicates with the elastic bladders. A plurality of spray holes are provided on the inner wall of the moving ring, and a water inlet is provided on the outer wall of the moving ring, which is suitable for adding water into the water storage cavity. The spray holes are arranged circumferentially along the inner wall of the moving ring and symmetrically arranged along the rack. The spray holes are conical, and the diameter gradually increases from the inner wall of the moving ring towards the water storage cavity. When the elastic bladder squeezes the cleaning cylinder and the fiber surface, water in the water storage cavity flows out through the spray holes to clean the cleaning cylinder and the fiber surface. The elastic bladder is adapted to move with the moving ring to squeeze the cleaning cylinder and the fiber surface again, so that the sewage is discharged.
[0017] In one optional embodiment, scraping rings are provided on both sides of the moving ring, with their extrusion ends extending towards the center of the moving ring. A dust collection groove is provided inside the moving ring, and two sets of long slots are provided on the inner wall of the moving ring, which are symmetrically arranged along the rack. A dust discharge port is provided on the outer wall of the moving ring. The width of the two sets of long slots gradually decreases from the inner wall of the moving ring towards the dust collection groove. The rack moves with the moving ring to comb the fibers, causing the particles to fall between the two scraping rings. The particles falling between the two scraping rings move with the moving ring and enter the dust collection groove from the long slots.
[0018] The beneficial effects of this utility model are that it provides a microchannel cleaning roller assembly for lithium battery heat exchangers. By setting a movable cleaning structure on the support rod, a moving ring can move back and forth on the cleaning cylinder. The fiber is combed by the rack and the moving ring squeezes the fiber and the surface of the cleaning cylinder, so that the cleaning cylinder in a wet state or a dry cleaning cylinder carrying particulate impurities can be cleaned without being removed from the support rod. This avoids long downtime during cleaning and effectively solves the problem of low production efficiency caused by cleaning the cleaning cylinder.

[0040] Research has revealed that existing cleaning cylinders employ an integral installation structure, with their rotating shaft rigidly connected to the drive unit via bolts or snap-fit mechanisms. When the cleaning cylinder fibers adsorb contaminants (especially ≥50μm metal dust) to a critical load, their wiping efficiency drops by more than 30%, and uneven pressure distribution leads to scratches on the inner wall of the microchannel (experimental data from the Journal of Metal Surface Engineering, 2022). At this point, the machine must be stopped to disassemble the cleaning cylinder for cleaning. The disassembly process requires workers to use specialized tools to operate on each locking component one by one, with each disassembly taking more than 15 minutes. In microchannel continuous processing production lines, such maintenance operations account for as much as 18%-25% of system downtime, severely restricting overall production efficiency.
[0041] Therefore, how to solve the problem of the need for the cleaning cylinder to pause the microchannel cleaning system for a long time is a technical problem that urgently needs to be solved in this field.
[0042] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0044] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0045] Example 1
[0046] like Figures 2 to 3As shown, this embodiment provides a cleaning roller assembly for microchannels used in lithium battery heat exchangers, including: a support rod 5 for supporting a cleaning cylinder 6; the cleaning cylinder 6 is fitted onto the support rod 5 and is used to clean the surface of the microchannel 8; the surface of the cleaning cylinder 6 is provided with cleaning fibers 61, and the cleaning cylinder 6 includes a sponge layer and a fabric layer, with the fibers 61 sewn onto the fabric layer; a cleaning structure 7 is fitted onto one end of the support rod 5. Specifically, when the cleaning cylinder 6 continuously cleans the surface of the microchannel 8, the cleaning structure 7 is fitted onto the support rod 5. When the cleaning cylinder 6 stops cleaning the surface of the microchannel 8, the cleaning structure 7 can be pushed to move from the support rod 5 onto the cleaning cylinder 6 and move back and forth on the cleaning cylinder 6 to achieve the cleaning purpose.
[0047] The cleaning structure 7 includes a moving ring 71, the inner diameter of which is smaller than the outer diameter of the cleaning cylinder 6. The inner wall of the moving ring 71 is provided with a rack 72. The moving ring 71 is configured to move along the axis of the support rod 5 so that the rack 72 combs the fibers 61 and squeezes the surface of the cleaning cylinder 6 and the fibers 61. The moving ring 71 can squeeze and rub the surface of the cleaning cylinder 6, and the rack 72 can comb the fibers 61 as the moving ring 71 moves.
[0048] Both sides of the moving ring 71 are provided with elastic bladders 73a, the squeezing ends of which extend toward the center of the moving ring 71. The inner diameter of the moving ring 71 is larger than the outer diameter of the cleaning cylinder 6, and the inner diameter of the elastic bladder 73a is smaller than the inner diameter of the moving ring 71 and the outer diameter of the cleaning cylinder 6. That is, the inner side of the elastic bladder 73a extends into the inner wall of the moving ring 71. The elastic bladder 73a is adapted to move with the moving ring 71 to squeeze the surface of the cleaning cylinder 6 and the fiber 61, so that the sewage is discharged. When the cleaning cylinder 6 is used to clean the microchannel 8 with water on the surface, the elastic bladder 73a has the effect of continuously squeezing out the water, so that the sewage absorbed by the cleaning cylinder 6 and the fiber 61 can be squeezed out.
[0049] The movable ring 71 has a water storage cavity 74a, which is connected to the elastic bladder 73a. The inner wall of the movable ring 71 has a plurality of spray holes 75a. The spray holes 75a are arranged circumferentially along the inner wall of the movable ring 71 and symmetrically arranged along the rack 72. The spray holes 75a are conical and the diameter gradually increases from the inner wall of the movable ring 71 toward the water storage cavity 74a. When the elastic bladder 73a squeezes the surface of the cleaning cylinder 6 and the fiber 61, water in the water storage cavity 74a flows out of the spray holes 75a to clean the surface of the cleaning cylinder 6 and the fiber 61. The outer wall of the moving ring 71 is provided with a water inlet 76a, which is suitable for adding water into the water storage chamber 74a. That is to say, when the elastic bladder 73a continuously squeezes the surface of the cleaning cylinder 6 and the fiber 61, the clean water inside will also be continuously sprayed from the spray hole 75a onto the cleaning cylinder 6 and the fiber 61, achieving a continuous cleaning effect. After the moving ring 71 leaves the cleaning cylinder 6, the elastic bladder 73a will rebound and maintain its initial state. At this time, water can be added to the water storage chamber 74a through the water inlet 76a. When the moving ring 71 moves back onto the cleaning cylinder 6, the elastic bladder 73a is squeezed again. While the spray hole 75a sprays water, the elastic bladder 73a squeezes out the water. Repeating this cycle several times can achieve a good cleaning effect. Finally, there is no need to add clean water to the water storage chamber 74a. It is only necessary to squeeze the water out of the cleaning cylinder 6 and the fiber 61 by the elastic bladder 73a.
[0050] Example 2
[0051] like Figures 2 to 4 As shown, this embodiment provides a cleaning roller assembly for microchannels used in lithium battery heat exchangers, including: a support rod 5 for supporting a cleaning cylinder 6; the cleaning cylinder 6 is fitted onto the support rod 5 and is used to clean the surface of the microchannel 8; the surface of the cleaning cylinder 6 is provided with cleaning fibers 61, and the cleaning cylinder 6 includes a sponge layer and a fabric layer, with the fibers 61 sewn onto the fabric layer; a cleaning structure 7 is fitted onto one end of the support rod 5. Specifically, when the cleaning cylinder 6 continuously cleans the surface of the microchannel 8, the cleaning structure 7 is fitted onto the support rod 5. When the cleaning cylinder 6 stops cleaning the surface of the microchannel 8, the cleaning structure 7 can be pushed to move from the support rod 5 onto the cleaning cylinder 6 and move back and forth on the cleaning cylinder 6 to achieve the cleaning purpose.
[0052] The cleaning structure 7 includes a moving ring 71, the inner diameter of which is smaller than the outer diameter of the cleaning cylinder 6. The inner wall of the moving ring 71 is provided with a rack 72. The moving ring 71 is configured to move along the axis of the support rod 5 so that the rack 72 combs the fibers 61 and squeezes the surface of the cleaning cylinder 6 and the fibers 61. The moving ring 71 can squeeze and rub the surface of the cleaning cylinder 6, and the rack 72 can comb the fibers 61 as the moving ring 71 moves.
[0053] Scraping rings 73b are provided on both sides of the moving ring 71, with their squeezing ends extending towards the center of the moving ring 71. The inner diameter of the moving ring 71 is larger than the outer diameter of the cleaning cylinder 6, and the inner diameter of the scraping rings 73b is smaller than the inner diameter of the moving ring 71 and the outer diameter of the cleaning cylinder 6. Thus, when the scraping rings 73b move back and forth along the cleaning cylinder 6 with the moving ring 71, they can squeeze the surface of the cleaning cylinder 6 and the limiting 61. It should be further explained that the cleaning cylinder 6 in this embodiment is used to clean the dried microchannels 8. The rack 72 moves with the moving ring 71 to comb the fibers 61, causing particles to fall between the two scraping rings 73b. When the rack 72 cleans the surface of the cleaning cylinder 6 and the limiting 61, particles and dust will fall off under the combing and friction of the rack 72 and fall between the two scraping rings 73b.
[0054] Additionally, a dust collection trough 74b is provided inside the moving ring 71, and two sets of elongated slots 75b are provided on the inner wall of the moving ring 71, symmetrically arranged along the rack 72; the width of the two sets of elongated slots 75b gradually decreases from the inner wall of the moving ring 71 towards the dust collection trough 74b. This design facilitates the entry of particles and prevents particles from being discharged. Particles falling between the two scraping rings 73b move with the moving ring 71 and enter the dust collection trough 74b through the elongated slots 75b. A dust discharge port 76b is provided on the outer wall of the moving ring 71. Dust and particles that fall off during combing and friction will enter the dust collection trough 74b through the elongated slots 75b as the moving ring 71 moves, and finally the dust can be discharged from the dust discharge port 76b, which can be sealed with a rubber plug.
[0055] Example 3
[0056] like Figures 1 to 3 As shown, this embodiment provides a microchannel cleaning system for a lithium battery heat exchanger, including: a conveying device 1, adapted to convey microchannels 8; a cleaning machine 2, disposed on one side of the conveying device 1; the cleaning machine 2 includes a rotating assembly 3 and a roller assembly 4, the roller assembly 4 being disposed on the rotating assembly 3; the cleaning machine 2 can clean the moving microchannels 8, the roller assembly 4 including a support rod 5, which is mounted on the rotating assembly 3 by a locking member; a cleaning cylinder 6, which is fitted onto the support rod 5, and the surface of the cleaning cylinder 6 is provided with cleaning fibers 61; a cleaning structure 7, which is fitted onto one end of the support rod 5; the cleaning structure 7 includes a moving ring 71, the inner diameter of which is smaller than the outer diameter of the cleaning cylinder 6, and the inner wall of the moving ring 71 is provided with a rack 72; wherein, the moving ring 71 is configured to move along the axial direction of the support rod 5 so that the rack 72 combs the fibers 61 and squeezes the cleaning cylinder 6 and the surface of the fibers 61.
[0057] To clean the microchannels 8 with wastewater on their surfaces, elastic bladders 73a are provided on both sides of the moving ring 71, with their extrusion ends extending towards the center of the moving ring 71. A water storage chamber 74a is provided inside the moving ring 71, which communicates with the elastic bladders 73a. Several spray holes 75a are provided on the inner wall of the moving ring 71, and a water inlet 76a is provided on the outer wall of the moving ring 71, which is suitable for adding water into the water storage chamber 74a. The spray holes 75a are arranged circumferentially along the inner wall of the moving ring 71 and symmetrically arranged along the rack 72. The spray holes 75a are conical, and their diameter gradually increases from the inner wall of the moving ring 71 towards the water storage chamber 74a. When the elastic bladders 73a extrude water from the cleaning cylinder 6 and the fiber 61, the water in the water storage chamber 74a flows through the spray holes 75a to clean the surface of the cleaning cylinder 6 and the fiber 61. The elastic bladders 73a are adapted to move with the moving ring 71 to extrude water from the cleaning cylinder 6 and the fiber 61 again, so that the wastewater is discharged.
[0058] Example 4
[0059] like Figures 1 to 2 and Figure 4 As shown, this embodiment provides a microchannel cleaning system for a lithium battery heat exchanger, including: a conveying device 1 adapted to convey microchannels 8; a cleaning machine 2 disposed on one side of the conveying device 1; the cleaning machine 2 includes a rotating assembly 3 and a roller assembly 4, the roller assembly 4 being disposed on the rotating assembly 3; the roller assembly 4 includes a support rod 5, which is mounted on the rotating assembly 3 by a locking member; a cleaning cylinder 6 fitted onto the support rod 5, the surface of the cleaning cylinder 6 being provided with cleaning fibers 61; a cleaning structure 7 fitted onto one end of the support rod 5; the cleaning structure 7 includes a moving ring 71, the inner diameter of which is smaller than the outer diameter of the cleaning cylinder 6, the inner wall of the moving ring 71 being provided with a rack 72; wherein, the moving ring 71 is configured to move along the axial direction of the support rod 5, so that the rack 72 combs the fibers 61 and squeezes the cleaning cylinder 6 and the surface of the fibers 61.
[0060] To clean the microchannels 8 with dry surfaces containing particulate impurities and dust, scraping rings 73b are provided on both sides of the moving ring 71, with their extrusion ends extending towards the center of the moving ring 71. A dust collection groove 74b is provided inside the moving ring 71, and two sets of elongated slots 75b are provided on the inner wall of the moving ring 71, which are symmetrically arranged along the rack 72. A dust discharge port 76b is provided on the outer wall of the moving ring 71. The width of the two sets of elongated slots 75b gradually decreases from the inner wall of the moving ring 71 towards the dust collection groove 74b. The rack 72 moves with the moving ring 71 to comb the fibers 61, causing particles to fall between the two scraping rings 73b. The particles falling between the two scraping rings 73b move with the moving ring 71 and enter the dust collection groove 74b from the elongated slots 75b.
[0061] In summary, by setting a movable cleaning structure 7 on the support rod 5, the moving ring 71 can move back and forth on the cleaning cylinder 6. The fiber 61 is combed by the rack 72, and the moving ring 71 squeezes the fiber 61 and the surface of the cleaning cylinder 6. This allows the cleaning cylinder, whether wet or dry but carrying particulate impurities, to be cleaned without being removed from the support rod 5. This avoids long downtime during cleaning and effectively solves the problem of low production efficiency caused by cleaning the cleaning cylinder.
