Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a water-cooling device. Background Technology

[0002] Currently, lithium battery production equipment, such as that used for coating substrates (substrate being electrodes or separators), generally includes an unwinding mechanism for unwinding the substrate, a coating mechanism for coating the substrate, a winding mechanism for rewinding the substrate, and several rollers for supporting the substrate. The coating mechanism generally includes a coating back roller, a coating motor for driving the coating back roller to rotate, a coating die head arranged opposite to the coating back roller, and a coating cylinder for driving the coating die head to move towards or away from the coating back roller. During the coating process on the substrate using lithium battery production equipment, friction exists between the high-speed rotating coating back roller and the substrate. This friction often generates a large amount of heat, which changes the viscosity of the slurry, causing fluctuations in the coating weight and reducing the coating quality. Furthermore, since the core components, namely the coating back roller and coating die head, are generally made of metal, this heat can also cause thermal expansion and deformation of the core components, thereby reducing the precision of the core components and further reducing the coating quality.

[0003] Therefore, a water-cooled cooling device is urgently needed to solve the above-mentioned technical problems. Utility Model Content

The top of the heat insulation cover is provided with a plurality of exhaust vents connected to the interior of the heat insulation cover. The plurality of exhaust vents are spaced apart along the length of the box structure. Each exhaust vent corresponds to an exhaust fan.

[0037] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0038] Please refer to Figures 1 to 3 An embodiment of this utility model provides a water-cooled cooling device, including two wall panels 10 arranged opposite each other, a heat insulation cover 20 with openings at both ends, a plurality of water-cooled radiators 30, a water inlet pipe 40 and a water outlet pipe 50.

[0039] Two wall panels 10 are respectively disposed at both ends of the heat insulation cover 20. In this embodiment, the two wall panels 10 are respectively disposed inside both ends of the heat insulation cover 20. The two wall panels 10 and the heat insulation cover 20 enclose and form a box structure. The outer side of the wall panel 10, i.e., the side of the wall panel 10 away from the center of the heat insulation cover 20, is provided with multiple mounting holes 11 that communicate with the interior of the heat insulation cover 20. The position and number of mounting holes 11 correspond to the position and number of the rollers and several passing rollers of the coating mechanism of the lithium battery production equipment. The rollers of the coating mechanism include coating back rollers. In actual application, the unwinding mechanism and the winding mechanism of the lithium battery production equipment are respectively set outside the box structure, while the coating mechanism and several passing rollers of the lithium battery production equipment are set inside the box structure. Specifically, the two ends of the rollers of the coating mechanism and the two ends of the passing rollers are respectively rotatably mounted in the corresponding mounting holes 11 of the two wall panels 10 through bearings. The coating motor of the coating mechanism is set on the inner side of one of the wall panels 10, i.e., the side of the wall panel 10 closer to the center of the heat insulation cover 20. The coating die head and coating cylinder of the coating mechanism are both set on the frame, and the frame is connected to the inner side of the two wall panels 10 respectively. The two wall panels 10 can provide mounting support for the coating mechanism and several passing rollers of the lithium battery production equipment. The heat insulation cover 20 is used to isolate the heat inside the enclosure structure from the external environment to prevent burns to operators.

[0040] The heat insulation cover 20 is provided with an inlet opening 21 and an outlet opening 22 communicating with its interior. The unwinding mechanism and the winding mechanism of the lithium battery production equipment correspond to the inlet opening 21 and the outlet opening 22, respectively. The substrate unwound by the unwinding mechanism can enter the box structure through the inlet opening 21. After being coated by the coating mechanism, the substrate can exit the box structure through the outlet opening 22 and be wound up by the winding mechanism. The substrate is an electrode sheet or a separator. In this embodiment, the inlet opening 21 is provided on one side of the heat insulation cover 20, and the outlet opening 22 is provided at the top of the heat insulation cover 20. Both the inlet opening 21 and the outlet opening 22 are elongated strip-shaped holes, which can ensure the low temperature effect inside the box structure. It can be understood that the position and length of the inlet opening 21 and the outlet opening 22 can be set according to the actual situation.

[0041] Several water-cooled radiators 30 are arranged sequentially from front to back within the heat insulation cover 20 along the width of the enclosure structure and are connected to the inner sides of two wall panels 10 respectively. The water-cooled radiators 30 are close to the top of the heat insulation cover 20. The two wall panels 10 provide installation support for the water-cooled radiators 30. In this embodiment, the membrane outlet 22 is located behind the water-cooled radiators 30. The inlet pipe 40 and the outlet pipe 50 are both located within the heat insulation cover 20, and parts of the inlet pipe 40 and the outlet pipe 50 extend from the through hole 12 of one of the wall panels 10, for example, the wall panel 10 located on the right, and are respectively used to connect to the outlet and return port of the water-cooled cabinet 100. The inlet end of each water-cooled radiator 30 is connected to the inlet pipe 40, and the outlet end of each water-cooled radiator 30 is connected to the outlet pipe 50.

[0042] A crossbeam 13 is provided between the two wall panels 10. The crossbeam 13 supports the wall panel 10 to prevent deformation. The number of crossbeams 13 can be set according to the actual situation.

[0043] With the above structure, in practical applications, the coating mechanism and several rollers of the lithium battery production equipment are arranged inside the housing structure. The two ends of the coating mechanism's rollers and the two ends of the rollers are rotatably mounted in the corresponding mounting holes 11 of the two wall plates 10 via bearings. The frame of the coating mechanism is connected to the inner sides of the two wall plates 10. Several water-cooled radiators 30 are located above the coating mechanism. During operation, the substrate unwound by the unwinding mechanism first enters the housing structure through the film inlet opening 21, then passes sequentially over the coating mechanism's rollers and several rollers, and finally exits through the film outlet opening 22 and is wound up by the winding mechanism. The coating mechanism can coat the substrate. The heat generated during the coating process is released into the housing structure, turning the room-temperature air inside the housing structure into hot air. During this process, the heat is released through the water-cooled cabinet 100. Cooling water can be introduced into the inlet pipe 40 through the outlet of the water-cooled cabinet 100. The cooling water then enters several water-cooled radiators 30. According to the principle of heat exchange, the cooling water entering the water-cooled radiators 30 can exchange heat with the hot air inside the cabinet structure, turning the hot air into low-temperature air. This removes the heat generated when the lithium battery production equipment coats the substrate, thus cooling the lithium battery production equipment. This prevents changes in slurry viscosity, keeps the coating weight stable, and improves coating quality. It also reduces deformation of core components, improves the precision of core components, and further improves coating quality. The cooling water after heat exchange becomes high-temperature water. The high-temperature water then flows back into the water-cooled cabinet 100 through the outlet pipe 50 and the return port of the water-cooled cabinet 100 for cooling, thus achieving circulation.

[0044] In this embodiment, combined with Figure 4 , Figure 5 and Figure 9 As shown, there are three water-cooled radiators 30, namely the first water-cooled radiator 30a, the second water-cooled radiator 30b, and the third water-cooled radiator 30c. The water inlet pipe 40 includes a main water inlet pipe 41 and a branch water inlet pipe structure. The water inlet ends of the first water-cooled radiator 30a, the second water-cooled radiator 30b, and the third water-cooled radiator 30c are all connected to the branch water inlet pipe structure. The branch water inlet pipe structure is connected to one end of the main water inlet pipe 41, and the other end of the main water inlet pipe 41 extends out from the through hole 12 and is used to connect to the outlet of the water-cooled cabinet 100. The water outlet pipe 50 includes a main water outlet pipe 51 and a branch water outlet pipe structure. The water outlet ends of the first water-cooled radiator 30a, the second water-cooled radiator 30b and the third water-cooled radiator 30b are all connected to the branch water outlet pipe structure. The branch water outlet pipe structure is connected to one end of the main water outlet pipe 51. The other end of the main water outlet pipe 51 extends out from the through hole 12 and is used to connect to the return port of the water-cooled cabinet 100.

[0045] The water inlet branch pipe structure includes a first water inlet branch pipe 42, a second water inlet branch pipe 43, a third water inlet branch pipe 44, and a fourth water inlet branch pipe 45. The water inlet end of the first water-cooled radiator 30a is connected to one end of the first water inlet branch pipe 42 via a T-junction. The water inlet end of the second water-cooled radiator 30b is connected to one end of the second water inlet branch pipe 43 via a T-junction. The other end of the first water inlet branch pipe 42 and the other end of the second water inlet branch pipe 43 are connected to one end of the third water inlet branch pipe 44 via a T-junction. The water inlet end of the third water-cooled radiator 30c is connected to one end of the fourth water inlet branch pipe 45 via a T-junction. The other ends of the third water inlet branch pipe 44 and the other ends of the fourth water inlet branch pipe 45 are connected to one end of the main water inlet pipe 41 via a T-junction. In practical applications, cooling water can be introduced into the water inlet main pipe 41 through the outlet of the water-cooled cabinet 100 and the other end of the water inlet main pipe 41. Subsequently, the cooling water in the water inlet main pipe 41 can enter the third water inlet branch pipe 44 and the fourth water inlet branch pipe 45 respectively. The cooling water entering the third water inlet branch pipe 44 can enter the first water inlet branch pipe 42 and the second water inlet branch pipe 43 respectively. The cooling water entering the first water inlet branch pipe 42 can enter the first water-cooled radiator 30a through the inlet end of the first water-cooled radiator 30a. Within the water-cooled radiator 30a, the cooling water entering the second inlet branch pipe 43 can enter the second water-cooled radiator 30b through the inlet end of the second water-cooled radiator 30b, and the cooling water entering the fourth inlet branch pipe 45 can enter the third water-cooled radiator 30c through the inlet end of the third water-cooled radiator 30c. The cooling water entering the first water-cooled radiator 30a, the second water-cooled radiator 30b, and the third water-cooled radiator 30c can exchange heat with the hot air inside the cabinet structure.

[0046] The water outlet branch pipe structure includes a first water outlet branch pipe 52, a second water outlet branch pipe 53, a third water outlet branch pipe 54, and a fourth water outlet branch pipe 55. The water outlet end of the first water-cooled radiator 30a is connected to one end of the first water outlet branch pipe 52 via a T-junction. The water outlet end of the second water-cooled radiator 30b is connected to one end of the second water outlet branch pipe 53 via a T-junction. The other ends of the first water outlet branch pipe 52 and the second water outlet branch pipe 53 are connected to one end of the third water outlet branch pipe 54 via a T-junction. The water outlet end of the third water-cooled radiator 30c is connected to one end of the fourth water outlet branch pipe 55 via a T-junction. The other ends of the third water outlet branch pipe 54 and the fourth water inlet branch pipe 55 are connected to one end of the main water outlet pipe 51 via a T-junction. In practical applications, the cooling water entering the first water-cooled radiator 30a, the second water-cooled radiator 30b, and the third water-cooled radiator 30c exchanges heat with the hot air inside the casing structure, becoming high-temperature water. The high-temperature water in the first water-cooled radiator 30a can enter the first outlet branch pipe 52 through its outlet end, and the high-temperature water in the second water-cooled radiator 30b can enter the second outlet branch pipe 53 through its outlet end. The high-temperature water entering the first outlet branch pipe 52... The warm water and the high-temperature water in the second outlet branch pipe 53 can enter the third outlet branch pipe 54. The high-temperature water in the third water-cooled radiator 30c can enter the fourth outlet branch pipe 55 through the outlet end of the third water-cooled radiator 30c. The high-temperature water entering the third outlet branch pipe 54 and the high-temperature water entering the fourth outlet branch pipe 55 can enter the outlet branch pipe 51. The high-temperature water entering the outlet branch pipe 51 can flow back to the water-cooled cabinet 100 through the other end of the outlet branch pipe 51 and the return port of the water-cooled cabinet 100 for cooling, so as to achieve circulation.

[0047] Combination Figures 4 to 8As shown, the water-cooled radiator 30 includes a serpentine heat pipe 31, which is made of copper. Using the serpentine heat pipe 31 increases the heat exchange area and improves heat transfer efficiency. Several L-shaped mounting members 32 are fitted onto the serpentine heat pipe 31. These mounting members 32 are spaced apart from left to right along the length of the casing structure. A fixing bracket 33 is provided at the top of each mounting member 32. The two ends of the fixing bracket 33 are connected to the inner sides of two wall panels 10, respectively. The serpentine heat pipe 31 and the two wall panels 10 are thus fixed together using the mounting members 32 and the fixing brackets 33. In this embodiment, each water-cooled radiator 30 has four mounting members 32 and two fixing brackets 33. Understandably, the number of mounting members 32 and fixing brackets 33 can be adjusted according to actual conditions. The first end of the serpentine heat pipe 31 is connected to an inlet pipe 311. The end of the inlet pipe 311 (the end furthest from the serpentine heat pipe 31) forms the inlet of the water-cooled radiator 30. The second end of the serpentine heat pipe 31 is connected to an outlet pipe 312. The end of the outlet pipe 312 (the end furthest from the serpentine heat pipe 31) forms the outlet of the water-cooled radiator 30. Cooling water can enter the serpentine heat pipe 31 through the end of the inlet pipe 311. The cooling water entering the serpentine heat pipe 31 can exchange heat with the hot air inside the casing structure. After the cooling water in the serpentine heat pipe 31 becomes high-temperature water, it can enter the outlet pipe 312 through the serpentine heat pipe 311, and then enter the outlet pipe 50 through the end of the outlet pipe 312.

[0048] Furthermore, the serpentine heat pipe 31 is fitted with several heat dissipation fins 34. The heat dissipation fins 34 are made of the same material as the serpentine heat pipe 31, and the several heat dissipation fins 34 are arranged alternately from left to right along the length of the casing structure. The heat dissipation fins 34 are rectangular in shape. The arrangement of several heat dissipation fins 34 can increase the heat exchange area and improve the heat transfer efficiency. The number of heat dissipation fins 34 can be set according to the actual situation.

[0049] In this embodiment, the serpentine heat dissipation pipe 31 includes multiple U-shaped pipes 313, which are distributed sequentially from front to back along the width direction of the casing structure. The first end of the first U-shaped pipe 313 is connected to the water inlet pipe 311, and the second end of the last U-shaped pipe 313 is connected to the water outlet pipe 312. In adjacent U-shaped pipes 311, the second end of the preceding U-shaped pipe 313 is connected to the first end of the following U-shaped pipe 313 via a bend 314. The number of U-shaped pipes 313 can be set according to actual conditions. This structure facilitates the manufacture of the serpentine heat dissipation pipe 31. The mounting component 32 and the heat dissipation fins 34 are fitted onto the U-shaped pipes 313.

[0050] Furthermore, this utility model also includes several intake fans 60 and several exhaust fans 70. One side of the heat insulation cover 20 is provided with several air inlets connected to the interior of the heat insulation cover 20. These air inlets are spaced apart along the length of the housing structure, with each air inlet corresponding to one intake fan 60, which is disposed within its respective air inlet. The top of the heat insulation cover 20 is provided with several exhaust vents connected to the interior of the heat insulation cover 20. These exhaust vents are spaced apart along the length of the housing structure, with each exhaust vent corresponding to one exhaust fan 70, which is disposed within its respective exhaust vent. The intake fans 60 can deliver ambient temperature air from outside the housing structure into the housing structure, while the exhaust fans 70 can exhaust hot air from inside the housing structure, thereby achieving heat exchange with the air outside the housing structure and removing the heat generated during the coating process of the lithium battery production equipment on the substrate. In this embodiment, there are four air inlets and four exhaust vents, therefore, there are also four intake fans 60 and four exhaust fans 70. Understandably, the number of air inlets, air outlets, intake fans 60, and exhaust fans 70 can be set according to actual conditions. In practical applications, when the lithium battery production equipment is coating the substrate, if the equipment generates excessive heat, the intake fans 60, exhaust fans 70, and several water-cooled radiators 30 will work together to quickly remove the heat generated during the coating process. When the equipment generates less heat, the intake fans 60 and exhaust fans 70 can be deactivated, saving energy and reducing the risk of external dust and other contaminants entering the enclosure structure.

[0051] The top of the heat insulation cover 20 is equipped with an exhaust duct 23, which is open at both the top and bottom. Several exhaust fans 70 are located inside the exhaust duct 23. The exhaust duct 23 can exhaust hot air inside the housing structure upwards, thus preventing operators from being burned due to proximity to lithium battery production equipment.

[0052] Furthermore, the intake fan 60 is an intake fan with a filter, and the exhaust fan 70 is an exhaust fan with a filter, which can reduce the risk of external dust and other pollutants entering the enclosure structure.

[0053] Furthermore, one of the wall panels 10, for example, the right-side wall panel 10, is provided with a first temperature sensor 81, a second temperature sensor 82, and a third temperature sensor 83 on its inner side. The first temperature sensor 81 is close to several air intake fans 60. The first temperature sensor 81 is used to monitor the temperature of the air entering the enclosure structure in order to control the operation of the several air intake fans 60. Specifically, during the operation of the several air intake fans 60, when the temperature of the air entering the enclosure structure is detected by the first temperature sensor 81 as being greater than the temperature inside the enclosure structure, the several air intake fans 60 are controlled to stop working. The second temperature sensor 82 is located below several water-cooled radiators 30. In practical applications, the second temperature sensor 82 corresponds to the position of the core component of the lithium battery production equipment. The second temperature sensor 82 is used to monitor the temperature at the location of the core component to control the operation of the water-cooled cabinet 100 or the operation of the water-cooled cabinet 100, the intake fan 60, and the exhaust fan 70. Specifically, when the temperature at the location of the core component detected by the second temperature sensor 82 is greater than a first predetermined temperature, the water-cooled cabinet 100 is started. Cooling water can be introduced into the several water-cooled radiators 30 through the outlet and inlet pipes 40 of the water-cooled cabinet 100, thereby removing the coating work of the lithium battery production equipment on the substrate. The heat generated during the coating process can be used to cool the lithium battery production equipment. When the temperature at the location of the core component is detected by the second temperature sensor 82 to be higher than the second predetermined temperature, the water-cooled cabinet 100, the intake fan 60, and the exhaust fan 70 are activated. Cooling water is introduced into the water-cooled radiators 30 through the water-cooled cabinet 100 outlet and the water inlet pipe 40. The intake fan 60 sends ambient air from outside the cabinet structure into the cabinet structure, and the exhaust fan 70 exhausts the hot air from inside the cabinet structure to the outside. This quickly removes the heat generated during the coating process of the lithium battery production equipment, thereby achieving rapid cooling of the lithium battery production equipment. The third temperature sensor 83 is located close to the top of the heat insulation cover 20 and behind the water-cooled radiators 30. The third temperature sensor 83 is used to monitor the temperature of the low-temperature air after heat exchange, so that operators know whether the lithium battery production equipment has cooled down. If the lithium battery production equipment has not cooled down, it is necessary to stop the machine for inspection.
