Description

Technical Field

[0001] This utility model relates to the field of cooling technology, and in particular to an industrial water chiller for cooling lithium battery production. Background Technology

[0002] The production of lithium batteries involves multiple complex processes, such as electrode manufacturing, cell assembly, formation, and capacity testing. Each of these processes generates a significant amount of heat. For example, during formation, internal chemical reactions produce substantial Joule heat; similarly, the charging and discharging processes during capacity testing release a large amount of heat. If this heat is not dissipated promptly and effectively, it will have a serious negative impact on the performance and quality of the lithium batteries.

[0003] Liquid cooling technology uses a coolant (such as water or ethylene glycol solution) as a heat exchange medium. The coolant absorbs heat generated by the battery through direct contact with the battery surface or by circulating through cooling pipes, and then transfers the heat to external heat dissipation equipment. Compared to air cooling, liquid cooling technology has advantages such as high heat dissipation efficiency and good heat dissipation uniformity, better meeting the heat dissipation requirements of high-energy-density lithium batteries.

[0004] Currently, industrial water chillers are widely used as a typical liquid cooling device in the field of lithium battery production cooling. An industrial water chiller is a cooling water device that can provide constant temperature, constant flow, and constant pressure. It can control the temperature of the cooling water within a certain range and deliver the cooling water to the equipment or parts that need cooling through a circulation system, achieving rapid cooling of the lithium batteries.

[0005] Existing industrial water chillers typically employ fixed cooling structures, such as cooling plates or cooling pipes, in their design and application, resulting in a relatively fixed contact area with lithium batteries. During lithium battery production, due to the significant size variations of batteries of different specifications and shapes, existing water chillers struggle to adjust their cooling structures to suit the actual size and shape of the batteries, leading to a small effective contact area between the cooling water and the battery. This insufficient heat dissipation area severely limits heat transfer efficiency, resulting in unsatisfactory battery cooling performance and failing to meet the requirements for rapid battery cooling during production.

[0006] Most existing industrial water chillers are designed for lithium batteries of specific specifications and shapes, lacking adaptability to batteries of different specifications and shapes. When it is necessary to change to different models of lithium batteries during the production process, existing water chillers are often unusable directly, requiring large-scale modifications or replacements of the cooling structure. This not only increases production costs and timelines but also affects production flexibility and efficiency. Furthermore, with the continuous development of lithium battery technology, the specifications and shapes of new batteries are constantly changing, and existing water chillers struggle to keep pace with these advancements, failing to meet the diverse needs of future lithium battery production. Utility Model Content

[0007] In view of the above situation and to overcome the defects of the prior art, this utility model provides an industrial water chiller for cooling in lithium battery production. This design effectively solves the problems of limited heat dissipation area and poor adaptability of conventional industrial water chillers in lithium battery production cooling applications.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a water-cooling assembly, the top of which is provided with a support plate, the top of which is provided with a first water-cooling plate, the top of which is provided with two second water-cooling plates, the two second water-cooling plates being symmetrically arranged about the center line of the support plate as an axis of symmetry, each second water-cooling plate having an adjustment component on its bottom outer side, the first water-cooling plate having a first circulation pipe inside, and the second water-cooling plate having a second circulation pipe inside.

[0009] Preferably, the bottom of the first circulation pipe is connected to the water cooling assembly.

[0012] Preferably, the outer side of the support frame is provided with a slide rail, and the bottom of the slide rail is connected to the support plate.

[0013] Preferably, the bottom of the second water-cooled plate is provided with a drive shaft, the outer end of the drive shaft is provided with a gear, the bottom of the gear is meshed with a rack, the outer side of the rack is provided with a second electric push rod, and the bottom of the second electric push rod is connected to the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The first water-cooled plate provides basic heat dissipation for the bottom of the lithium battery. Its internal circulation pipe forms a circulation with the water-cooling component to quickly remove heat from the bottom. Two symmetrical second water-cooled plates increase the contact area with the battery and can absorb heat from the sides and other parts to improve heat dissipation efficiency. The first electric push rod in the adjustment component drives the support frame and the second water-cooled plate to move horizontally to adapt to batteries of different widths. The extension and retraction of the second electric push rod drives the rack to move. The relative movement of the rack and gear causes the gear to rotate. The gear drives the second water-cooled plate to rotate through the transmission shaft, realizing angle adjustment. It can change the angle of the second water-cooled plate according to the lithium battery with different tilt angles, so that it fits tightly against the battery surface and improves the heat dissipation effect.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-6 The specific embodiments of this utility model will be described in further detail.

[0023] This utility model includes a water-cooling assembly 101, which is the core cooling source of the entire water chiller. It integrates key components such as a refrigeration system, a water pump, and a water tank. The refrigeration system cools the water in the water tank, maintaining it at a set low temperature. The water pump draws the low-temperature cooling water from the water tank and delivers it to other components through pipelines. The water tank stores the cooling water, ensuring a continuous supply. The water-cooling assembly 101 provides stable and continuous cooling for the entire water chiller, forming the basis for cooling the lithium battery. A support plate 102 is located on top of the water-cooling assembly 101, serving to support and bear the load of the upper structure. It possesses sufficient strength and rigidity to stably support the first water-cooled plate 103 and the second water-cooled plate 104 on top of it, ensuring the structural stability of the entire water chiller during operation. It will not deform or be damaged due to the weight of the upper components or the impact force when the battery is placed. The first water-cooled plate 103 is located on the top of the support plate 102, and two second water-cooled plates 104 are located on the top of the first water-cooled plate 103. The two second water-cooled plates 104 are symmetrically arranged about the center line of the support plate 102. Each second water-cooled plate 104 has an adjustment component on its bottom outer side. The first water-cooled plate 103 has a first circulation pipe 105 inside, and the bottom of the first circulation pipe 105 is connected to the water-cooling assembly 101. The second water-cooled plate 104 has a second circulation pipe 106 inside, and the bottom of the second circulation pipe 106 is connected to the water-cooling assembly 101. The bottom of the first circulation pipe 105 is also connected to the water-cooling assembly 101, forming a cooling water circulation channel. Cooling water enters the first circulation pipe 105 from the water-cooling assembly 101. During its flow inside the first water-cooling plate 103, it absorbs heat from the area in contact with the first water-cooling plate 103, and then flows back to the water-cooling assembly 101 for cooling. This cycle repeats continuously, achieving heat dissipation in the area where the first water-cooling plate 103 is located. The first water-cooling plate 103 provides a basic heat dissipation surface for the bottom of the lithium battery, quickly removing heat generated at the bottom of the battery. The design of the second water-cooling plate 104 increases the contact area between the water chiller and the lithium battery, enabling it to absorb heat from more parts of the battery, such as the sides, further improving heat dissipation efficiency.

[0024] Each second water-cooled plate 104 has an adjustment component on its bottom outer side. The adjustment component is a key component for adjusting the position and angle of the second water-cooled plate 104, enabling the second water-cooled plate 104 to move in position and rotate in angle. The design of the adjustment component allows the second water-cooled plate 104 to be flexibly adjusted according to lithium batteries of different sizes and tilt angles, ensuring that the second water-cooled plate 104 can fit tightly against the battery surface and improve the heat dissipation effect.

[0025] The adjustment assembly includes a first electric push rod 201. The bottom of the first electric push rod 201 is connected to the support plate 102. A support frame 202 is provided on the outer side of the first electric push rod 201. The extension and retraction of the first electric push rod 201 can drive the support frame 202 to move inward or outward. The inner side of the support frame 202 is rotatably connected to the bottom of the corresponding second cold water plate, thereby realizing the initial adjustment of the horizontal position of the second water-cooled plate 104.

[0026] The outer side of the support frame 202 is provided with a slide rail 203. The bottom of the slide rail 203 is connected to the support plate 102. The slide rail 203 can support the horizontal movement of the support frame 202.

[0027] The bottom of the second water-cooled plate 104 is provided with a drive shaft 207, and the outer end of the drive shaft 207 is provided with a gear 206. The bottom of the gear 206 is meshed with a rack 205. The outer side of the rack 205 is provided with a second electric push rod 204. The bottom of the second electric push rod 204 is connected to the support plate 102. The extension and retraction of the second electric push rod 204 can drive the rack 205 to move. The rack 205 can drive the gear 206 to rotate. The gear 206 realizes the angle adjustment of the second water-cooled plate 104 through the drive shaft 207.

[0028] When the position of the second water-cooling plate 104 needs to be adjusted according to lithium batteries of different widths, the control component simultaneously controls the first electric push rod 201 and the second electric push rod 204 to move inward or outward with the same extension length. The first electric push rod 201 drives the support frame 202 to move horizontally on the slide rail 203, and the support frame 202 drives the second water-cooling plate 104 to move synchronously, thereby realizing the vertical movement of the second water-cooling plate 104. This ensures that the distance between the two second water-cooling plates 104 adapts to the width of the battery, ensuring that the battery can be smoothly placed between the first water-cooling plate 103 and the second water-cooling plate 104.

[0029] When the angle of the second water-cooling plate 104 needs to be changed to accommodate lithium batteries at different tilt angles, the control component controls the extension length of the second electric push rod 204 to be different from that of the first electric push rod 201. At this time, the second electric push rod 204 drives the rack 205 to move, and relative movement occurs between the rack 205 and the gear 206, causing the gear 206 to rotate. The gear 206 transmits this rotation to the second water-cooling plate 104 via the transmission shaft 207, thereby changing the angle of the second water-cooling plate 104. This allows the second water-cooling plate 104 to fit tightly against the tilted surface of the battery, improving heat dissipation.

[0030] After the second water-cooling plate 104 is adjusted to the appropriate position and angle, the water-cooling assembly 101 begins to operate. The refrigeration system cools the water in the tank to a low temperature, and the water pump delivers the low-temperature cooling water to the first circulation pipe 105 of the first water-cooling plate 103 and the second circulation pipe 106 of the second water-cooling plate 104. As the cooling water flows through the circulation pipes, it absorbs the heat generated by the battery and then flows back to the water-cooling assembly 101 for further cooling. This cycle repeats continuously, achieving efficient heat dissipation for the lithium battery.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
