Description

Technical Field

[0001] This utility model relates to the field of lithium battery production, specifically to an integrated hydrothermal high-temperature water-cooled power supply formation device. Background Technology

[0002] In lithium battery production, environmental control of the formation process is extremely strict. To meet this environmental control standard, both equipment and factory buildings incur significant costs. The industry typically uses environmental control methods, such as high-temperature blowers and pipelines, with negative pressure used to address battery bulging issues and high temperature (45°C) used to reduce charging and discharging time. The power supply unit is placed in a separate room at room temperature (25°C), where cooling is achieved by introducing cold air and expelling hot air.

[0003] High temperature achievement: Hot air pipes are laid out inside the formation machine. The temperature of the formation room is raised and maintained at 45±3℃ through hot air circulation. The formation workshop is a large space. Heating the entire workshop consumes a lot of energy and it is difficult to control the temperature uniformity. It also places extremely high requirements on the plant infrastructure.

[0004] Heat dissipation of the power supply section: The power supply section is a high-power device that generates a lot of heat. If the heat is not dissipated in time, the temperature in the workshop will increase, which will affect the life of the equipment. At present, the industry generally uses air cooling. By supplying cold air to the workshop, the cold air passes through the power supply section and carries away the heat. The workshop collects the hot air and exhausts it outside the factory. This air cooling circulation system is also extremely energy-intensive.

[0005] In summary, the environmental control of the formation process in lithium battery production is extremely strict. To meet this environmental control standard, both equipment and factory buildings incur significant costs. Environmental control places extremely high demands on the lithium battery formation process, and current industry practices are quite complex, involve numerous environmental controls, are difficult to implement, and consume a great deal of energy. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide an integrated hydrothermal high-temperature water-cooled power supply formation device to solve the technical problems of extremely strict and complex external environmental requirements in the traditional lithium battery production process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hydrothermal high-temperature water-cooled power supply integrated formation device, comprising a mechanical part and a power supply part. Hydrothermal components are provided on both sides of the mechanical part for heat exchange. Water-cooled components are provided on both sides of the power supply part for heat exchange. The hydrothermal components include a first heat exchanger, which is connected to an external water storage device and a water heating device via an inlet pipe, a return pipe, and a water pump. The water-cooled components include a second heat exchanger, which is connected to an external liquid storage device and a liquid heat dissipation device via a liquid inlet pipe, a liquid return pipe, and a liquid pump.

[0008] By adopting the above technical solution, this hydrothermal high-temperature water-cooled power supply integrated formation equipment achieves efficient thermal management of the two parts through the independent design of the mechanical part and the power supply part. The hydrothermal components set on both sides of the mechanical part can accurately heat and ensure the temperature environment required for the formation process.

[0009] Furthermore, the two sets of the first heat exchangers are mirror-mounted on both sides of the mechanical part and located inside the cavity of the stainless steel shell, and a stainless steel mesh plate is horizontally installed on the inner side of the cavity.

[0010] By adopting the above technical solution, the first heat exchanger is placed inside the cavity of the stainless steel shell, which ensures the uniform distribution of heat. At the same time, the stainless steel mesh plate installed inside the cavity not only enhances the stability of the structure, but also plays a role in heat conduction and heat equalization.

[0011] Furthermore, several first fans are installed on the stainless steel plates on both sides of the mechanical part, and several second fans are installed on the top of the mechanical part. The multiple first fans and second fans are arranged in a rectangular array.

[0012] By adopting the above technical solution, the first and second fans installed on both sides and above the mechanical part are arranged in a rectangular array to form a powerful airflow circulation system. At the same time, this system can quickly transfer heat and promote air circulation, providing a good environment for the lithium battery formation process.

[0013] Furthermore, the mounting cavity of the first heat exchanger is connected to the inner side of the mechanical part through the first fan mounting location.

[0014] By adopting the above technical solution, direct heat transfer is achieved, reducing heat loss. At the same time, the interconnected structure allows air inside the mechanical part to circulate, further improving heat exchange efficiency.

[0015] Furthermore, the two sets of the second heat exchangers are mirror-mounted on both sides of the power supply section and located inside the cavity of the stainless steel shell, and a stainless steel ventilation plate is horizontally installed inside the cavity.

[0016] By adopting the above technical solution, the two sets of second heat exchangers are mirror-mounted on both sides of the power supply unit and placed inside the cavity of the stainless steel shell, ensuring the effective dissipation of heat from the power supply unit.

[0017] Furthermore, several third fans are installed on the stainless steel plates on both sides of the power supply unit, and several fourth fans are installed on the top of the power supply unit. The multiple third fans and fourth fans are arranged in a rectangular array.

[0018] By adopting the above technical solution, the third and fourth fans installed on both sides and the top of the power supply unit are arranged in a rectangular array to form a powerful airflow circulation system. This system can quickly discharge the heat absorbed by the heat exchanger to the outside of the equipment, ensuring the stable operation of the power supply unit.

[0019] Furthermore, the installation cavity of the second heat exchanger is connected to the installation location of the third fan, the ventilation plate, and the power supply unit through a structure that allows for communication between them.

[0020] By adopting the above technical solution, rapid heat transfer and dissipation are achieved. At the same time, the interconnected structure allows air to circulate inside the power supply unit, further improving heat dissipation efficiency. This not only ensures the temperature stability of the power supply unit during high-load operation but also avoids power supply failures caused by excessive temperature.

[0021] Furthermore, the mechanical part includes a tray assembly, and a suction nozzle mechanism is provided above the tray assembly. The tray assembly and the suction nozzle mechanism are fastened together by a snap-fit.

[0022] By adopting the above technical solution and designing an integrated tray, the suction nozzle mechanism and the tray assembly are integrated together, ensuring that the battery's internal environment is isolated from the external environment throughout the entire process. Since the battery no longer comes into contact with the outside, the control of the dryness of the workshop environment can be relaxed.

[0023] Furthermore, the top of the integrated hydrothermal high-temperature water-cooled power supply formation equipment is equipped with a ventilation opening to balance the internal air pressure of the equipment.

[0024] By adopting the above technical solution, the vent can balance the air pressure inside the equipment, avoiding equipment damage or performance degradation caused by air pressure differences. At the same time, the vent also plays the role of exhaust and air exchange, effectively removing harmful gases and moisture generated inside the equipment, and providing a good environment for the lithium battery formation process.

[0025] Furthermore, a movable door is provided on one side of the mechanical part, and a transparent observation window is provided on the movable door. A maintenance part is provided in the middle of the integrated hydrothermal high-temperature water-cooled power supply formation equipment.

[0026] By adopting the above technical solutions, the movable door facilitates operators to observe and maintain the inside of the equipment. The transparent observation window on the movable door allows operators to understand the internal operating status of the equipment without opening it, improving the safety and convenience of operation. At the same time, the maintenance section in the middle of the integrated hydrothermal high-temperature water-cooled power supply formation equipment provides operators with a spacious maintenance space, facilitating regular maintenance and upkeep of the equipment.

[0027] In summary, the present invention has the following main advantages:

[0028] 1. This utility model uses a hydrothermal component. The inlet pipe introduces hot water as a medium into the first heat exchanger inside the equipment. The hot water releases heat in the first heat exchanger. At the same time, the return pipe is used to discharge the cooled water, forming a circulation. Then, the first and second fans inside the equipment are started to send the heat from the first heat exchanger into the storage area, realizing local heating. This not only ensures the high efficiency of heat transfer, but also takes safety into account, avoiding the safety hazards that may be caused by direct contact between water and electricity. Through the individual action of this hydrothermal component, the temperature inside the storage area can be raised to 45°C without heating the entire workshop. This change significantly reduces the total heating power and has high hydrothermal efficiency, significantly reducing the operating cost of the equipment.

[0029] 2. This utility model incorporates a water-cooling component. The inlet pipe introduces cold water as a medium into the water-cooling component within the equipment. The cold water absorbs heat generated by the power supply within the water-cooling component. Simultaneously, the return pipe discharges the heat-absorbing hot water, forming a circulating heat dissipation system. During this process, the water-cooling component employs a water-air separation design, ensuring the safety of the cooling process and avoiding the risks associated with direct contact between water and electricity. Through the independent action of this water-cooling component, heat within the storage area is effectively removed without requiring heat dissipation for the entire workshop. This modification significantly reduces the total cooling power, as heat dissipation is only needed for localized areas within the equipment, eliminating the need for temperature control of the entire workshop. Furthermore, due to the high thermal efficiency of water, this heat dissipation method significantly reduces the operating costs of the equipment. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Example 1:

[0037] A hydrothermal high-temperature water-cooled power supply integrated formation device, such as Figures 1-4 As shown, the device includes a mechanical section 1 and a power supply section 3. Both sides of the mechanical section 1 are equipped with hydrothermal components 2 for heat exchange. Both sides of the power supply section 3 are equipped with water-cooling components 4 for heat exchange. The hydrothermal components 2 include a first heat exchanger 201, which is connected to an external water storage device and a water heating device via an inlet pipe 202, a return pipe 203, and a water pump. The water-cooling components 4 include a second heat exchanger 401, which is connected to an external liquid storage device and a liquid heat dissipation device via an inlet pipe 402, a return pipe 403, and a liquid pump. This integrated hydrothermal high-temperature water-cooled power supply chemical formation equipment achieves efficient thermal management of both parts through the independent design of the mechanical section 1 and the power supply section 3. The hydrothermal components 2 on both sides of the mechanical section 1 can precisely heat the equipment, ensuring the required temperature environment for the chemical formation process. Simultaneously, the water-cooling components 4 on both sides of the power supply section 3 effectively dissipate heat, ensuring stable power supply operation. This design not only improves the overall energy efficiency of the equipment but also reduces energy consumption.

[0038] See Figure 1 , Figure 3 Two sets of first heat exchangers 201 are mirror-mounted on both sides of the mechanical part 1 and located inside the cavity of the stainless steel shell. A stainless steel mesh plate 204 is horizontally installed inside the cavity. The placement of the first heat exchangers 201 inside the cavity of the stainless steel shell ensures uniform heat distribution. At the same time, the stainless steel mesh plate 204 inside the cavity not only enhances the structural stability but also plays a role in heat conduction and heat equalization. This design enables the mechanical part to reach the required temperature in a short time and maintain stability.

[0039] See Figure 1 , Figure 3Several first fans 205 are installed on the stainless steel plates on both sides of the mechanical part 1, and several second fans 206 are installed above the mechanical part 1. The multiple first fans 205 and second fans 206 are arranged in a rectangular array. The first fans 205 and second fans 206 installed on both sides and above the mechanical part 1 form a powerful airflow circulation system through the rectangular array arrangement. At the same time, this system can quickly transfer heat and promote air circulation, providing a good environment for the lithium battery formation process. In addition, the rectangular array arrangement of the fans also optimizes the airflow path and reduces energy consumption and noise.

[0040] See Figure 1 , Figure 3 The mounting cavity of the first heat exchanger 201 is connected to the inner side of the mechanical part 1 through the mounting location of the first fan 205, realizing direct heat transfer and reducing heat loss. At the same time, the connection structure also allows the air inside the mechanical part 1 to circulate, further improving the heat exchange efficiency. This not only ensures the rapid rise and stable maintenance of the temperature of the mechanical part 1, but also avoids the performance differences of lithium batteries caused by uneven temperature. In addition, the connection structure facilitates the maintenance and cleaning of the equipment, improving the reliability and service life of the equipment.

[0041] Example 2:

[0042] See Figure 2 , Figure 4 Two sets of second heat exchangers 401 are mirror-mounted on both sides of the power supply unit 3 and located inside the cavity of the stainless steel shell. A stainless steel ventilation plate 404 is horizontally installed inside the cavity. The mirror-mounted second heat exchangers 401 on both sides of the power supply unit 3 and located inside the cavity of the stainless steel shell ensures effective heat dissipation of the power supply unit 3. At the same time, the stainless steel ventilation plate 404 inside the cavity not only enhances the structural stability but also guides airflow and dissipates heat. This design enables the power supply unit to maintain a low temperature during high-load operation.

[0043] See Figure 2 , Figure 4 Several third fans 405 are installed on the stainless steel plates on both sides of the power supply section 3, and several fourth fans 406 are installed on the top of the power supply section 3. The multiple third fans 405 and fourth fans 406 are arranged in a rectangular array. The third fans 405 and fourth fans 406 installed on the sides and top of the power supply section 3 form a powerful airflow circulation system through the rectangular array arrangement. This system can quickly expel the heat absorbed by the heat exchanger to the outside of the equipment, ensuring the stable operation of the power supply section. At the same time, the operation of the fans also promotes air circulation inside the equipment, effectively reduces the temperature gradient of the power supply section 3, and improves heat dissipation efficiency. In addition, the rectangular array arrangement of the fans also optimizes the heat dissipation performance of the equipment and reduces energy consumption and noise.

[0044] See Figure 2 , Figure 4 The installation cavity of the second heat exchanger 401 is connected to the installation position of the power supply unit 3 through the installation location of the third fan 405 and the ventilation plate 404, realizing rapid heat transfer and dissipation. At the same time, the connection structure also allows the air inside the power supply unit 3 to circulate, further improving the heat dissipation efficiency. This not only ensures the temperature stability of the power supply unit 3 during high-load operation, but also avoids power failure caused by excessive temperature. In addition, the connection structure facilitates the heat dissipation maintenance and cleaning of the equipment, improving the reliability and service life of the equipment.

[0045] See Figure 1 , Figure 2 , Figure 3 The mechanical section 1 includes a tray assembly 101, with a suction nozzle mechanism 102 mounted on top of the tray assembly 101. The tray assembly 101 and the suction nozzle mechanism 102 are fastened together by a snap-fit. By designing an integrated tray, the suction nozzle mechanism 102 and the tray assembly 101 are integrated together, ensuring that the battery's internal environment is isolated from the external environment during the entire circulation process. Since the battery no longer comes into contact with the outside, the dryness control of the workshop environment can be relaxed. When the tray is put into the mechanical section 1, the suction nozzle mechanism 102 is automatically connected to the negative pressure device on the mechanical section 1 to ensure the normal operation of the negative pressure function.

[0046] See Figure 1 The top of the hydrothermal high-temperature water-cooled power supply integrated formation equipment has a ventilation port 7, which is used to balance the internal air pressure of the equipment. The ventilation port 7 can balance the internal air pressure of the equipment and avoid equipment damage or performance degradation caused by air pressure differences. At the same time, the ventilation port 7 also plays the role of exhaust and ventilation, effectively removing harmful gases and moisture generated inside the equipment, providing a good environment for the lithium battery formation process. This not only ensures the stable operation of the equipment, but also extends the service life of the equipment. In addition, the design of the ventilation port 7 also facilitates the heat dissipation and maintenance of the equipment, improving the reliability and safety of the equipment.

[0047] See Figure 1 , Figure 2A movable door 6 is provided on one side of the mechanical part 1, and a transparent observation window is provided on the movable door 6. A maintenance part 5 is provided in the middle of the integrated hydrothermal high-temperature water-cooled power supply formation equipment. The movable door 6 facilitates the operator's observation and maintenance of the equipment's interior. The transparent observation window on the movable door 6 allows the operator to understand the internal operating status of the equipment without opening it, improving the safety and convenience of operation. At the same time, the maintenance part 5 in the middle of the integrated hydrothermal high-temperature water-cooled power supply formation equipment provides the operator with a spacious maintenance space, facilitating regular maintenance and upkeep of the equipment. This not only improves the maintainability of the equipment but also reduces maintenance costs and time. In addition, the movable door 6 and the maintenance part 5 enhance the overall aesthetics and practicality of the equipment.

[0048] The implementation principle of this utility model is as follows:

[0049] Achieving a 45℃ environment: Using hot water as the medium, heat is introduced into the first heat exchanger 201 inside the equipment through the inlet pipe 202 and the return pipe 203. Then, the heat is delivered into the storage area by the first fan 205 and the second fan 206 inside the equipment. The water-air separation design takes into account both safety and efficiency. Through this hydrothermal component 2, the temperature inside the storage area is raised separately, avoiding heating the entire workshop. Instead, heating is changed from heating the entire workshop to local heating inside the equipment, which greatly reduces the total heating power and has high hydrothermal efficiency, thereby reducing the operating cost of the equipment.

[0050] Improved power supply heat dissipation: Using cold water as the medium, the heat from the power supply unit 3 is carried out of the storage location through the liquid inlet pipe 402 and the liquid return pipe 403. The water-air separation design takes into account both safety and efficiency. Through this water-cooling component 4, the heat in the storage location can be carried away separately, eliminating the need to dissipate heat for the entire workshop. The temperature control of the entire workshop is changed to local heat dissipation inside the equipment, which greatly reduces the total cooling power and has high water thermal efficiency, thereby reducing the operating cost of the equipment.

[0051] By adopting the above technical approach, the requirements for factory buildings can be reduced, and factories that require strict environmental control can be changed to ordinary factories, which greatly reduces the construction and operating costs of the workshop.

[0052] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
