Description

Technical Field

[0001] The present application relates to the field of new energy, and in particular to a multi-channel liquid cooling plate. Background Art

[0002] In the energy storage industry, especially in the field of electric storage, effective temperature control is a key factor in ensuring the stability of battery performance and extending its life. With the widespread application of renewable energy and the rapid growth of the electric vehicle market, the demand for efficient and reliable battery energy storage systems is increasing. These systems usually include multiple battery modules, which generate heat during operation. If not controlled, overheating may cause battery performance degradation, shortened life, and even safety accidents. Therefore, the development of effective battery module temperature control technology has become an important research direction in this field.

[0003] In recent years, with the advancement of technology and the increase in market demand, the field of power storage has paid particular attention to improving the energy density of battery modules, reducing costs, and ensuring the safety and reliability of the system. In this context, temperature control technology, especially liquid cooling technology, has become the preferred technology in battery thermal management systems (BTMS) due to its efficient heat transfer performance and good temperature balancing ability. Liquid cooling technology can effectively extract heat from battery modules and avoid the formation of hot spots, thereby protecting the battery and improving its performance and safety.

[0004] Although liquid cooling technology has obvious advantages in battery temperature control, the currently commonly used liquid cooling plates have some shortcomings in the design and production process, especially in terms of structural complexity and cost-effectiveness. Although the current liquid cooling plates, especially the versions with complex flow channel designs, perform well in thermal management, their complex structures make the production cost high and not easy for large-scale industrial applications. In addition, these complex designs also pose challenges in maintenance and repair, especially when the liquid cooling plate is damaged due to collision or other reasons, the cost and difficulty of replacement or repair are high.

[0005] Given these limitations of existing liquid cooling plate technology, it is particularly important to develop a new type of liquid cooling plate with a simpler structure, lower cost, and easy maintenance. The harmonica-type liquid cooling plate has become a promising alternative with its relatively simple structure and low cost. This design simplifies the manufacturing process of the liquid cooling plate, helps to reduce production costs, and is suitable for mass production. However, the existing harmonica-type liquid cooling plate adopts a full-channel structure, which simplifies the design but has defects in later maintainability and repairability. Once leakage occurs, repair or replacement work is complicated and costly.

[0006] Therefore, developing a new type of liquid cooling plate that can combine efficient heat dissipation performance with better maintainability and cost-effectiveness is of great significance to promoting technological progress and industrial applications in the field of power storage. Utility Model Content

[0007] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a multi-channel liquid cooling plate that is easy to repair and replace and can quickly handle problems such as leakage even in a tightly integrated battery system, thereby reducing maintenance costs and improving system reliability and safety.

[0008] To achieve the above-mentioned purpose, the present application discloses a multi-channel liquid cooling plate, including a plate body and a plug assembly, wherein the plate body is provided with a plurality of straight flow channels which penetrate along the length direction of the plate body, and each straight flow channel is evenly arranged in the width direction of the plate body; two plug assemblies are detachably fixed on the two end parts of the plate body in the two length directions, and are used to seal the opening of the direct flow channel at the end part of the plate body; the plug assembly is connected and cooperated with at least one straight flow channel; the plug assembly includes a main body and a plug, wherein the main body is provided with a secondary flow channel for cooperating with the straight flow channel, and the main body is provided with a plurality of openings connected to the secondary flow channel and an interface connected to the secondary flow channel; the number and position of the openings are suitable for the direct flow channel, and at least one opening is detachably sealed by the plug; in the two plug assemblies, one of the interfaces in one plug assembly is used as a liquid inlet, and correspondingly, the interfaces in the other plug assembly are used as a liquid outlet, and the liquid inlet and the liquid outlet are respectively connected to an external circulating liquid cooling device to realize circulating liquid supply to the straight flow channel in the plate body.

[0009] Furthermore, the two end faces of the plate body in the length direction are flat, and an annular groove is provided at the opening of each linear flow channel. Correspondingly, a sealing ring that cooperates with the annular groove is provided on the plug assembly. When the plate body and the plug assembly are matched, the sealing ring partially enters the annular groove to achieve connection sealing.

[0010] Furthermore, the main body of the plug assembly is protrudingly provided with a plug portion that is adapted to the number of openings, and the openings of the plug assembly are located on the plug portion. When the plug assembly is matched with the plate body, the plug portion is partially inserted into the straight flow channel, so that the corresponding openings are connected to the straight flow channel, and then the corresponding straight flow channel is connected and matched with the secondary flow channel.

[0011] Furthermore, the plug assembly is detachably fixed to the end of the plate body by bolts.

[0012] In the above structure, by adjusting the sealing state of the opening in the plug assembly, the straight flow channel operation can be selected.

[0013] Compared with the prior art, the application has at least one beneficial effect;

[0014] 1. Improved maintainability and repairability of the system: By adopting a detachable plug assembly and a body designed with a secondary flow channel, this technical solution allows for easy access or closure of the linear flow channel inside the liquid cooling plate, so that when leakage occurs or maintenance is required, the problematic flow channel can be quickly located and handled without replacing the entire liquid cooling plate. This design greatly simplifies the maintenance process, reduces maintenance costs and time, and improves the overall reliability of the battery system.

[0015] 2. Optimized thermal management efficiency: By precisely controlling the flow path of the liquid, that is, selectively using specific linear channels for cooling, more refined temperature control can be achieved according to the specific heat load requirements of the battery module. This flexible channel management not only improves the cooling efficiency, but also helps to maintain the uniformity of the temperature inside the battery module, thereby improving battery performance and extending its service life. In addition, by adjusting the sealing state of the opening in the plug assembly, a specific linear channel can be flexibly selected for operation, allowing the liquid cooling plate to adjust the cooling strategy according to different working conditions and requirements. This improvement in adaptability and flexibility enables the liquid cooling plate to better meet the changing application scenarios and environmental requirements, further expanding its scope of application.

[0016] 3. Reduced production and operating costs: The structure of the liquid cooling plate is simplified. Compared with the traditional complex flow channel design, this simplified design helps to reduce manufacturing costs. At the same time, due to its optimized maintainability and repairability, the operating cost is also reduced accordingly. This improvement in cost-effectiveness makes this technical solution more suitable for large-scale industrial applications.

[0028] Figure 1-3 An exemplary structure for achieving the technical purpose of the present application is shown. As shown in the figure, in this embodiment, it is a multi-channel liquid cooling plate, which is designed to provide an efficient, reliable and easy-to-maintain battery module cooling solution. This embodiment mainly consists of two parts, a plate body 1 and a plug assembly 2.

[0029] Specifically, the plate body 1 is the main part of the liquid cooling plate, and is provided with a plurality of straight flow channels 3 running through the length direction of the plate body 1, and these flow channels 3 are evenly arranged in the width direction of the plate body 1. The straight flow channels 3 are to allow the cooling medium to flow efficiently, thereby taking away the heat generated by, for example, a battery module or a battery pack.

[0030] More specifically, both end surfaces of the plate body 1 are flat, and an annular groove 8 is provided at the end surface at the opening of each linear flow channel 3 for cooperating with the sealing ring 9 of the plug assembly 2 to achieve a sealed connection.

[0031] In this embodiment, the plug assembly 2 is detachably mounted at both ends of the plate body 1, and is used to seal the opening of the linear flow channel 3 at the end of the plate body 1. Each plug assembly 2 can be connected and matched with at least one linear flow channel 3 to ensure the smooth flow of the cooling medium. The plug assembly 2 is composed of a body 4 and a plug 5, wherein the body 4 is provided with a secondary flow channel matched with the linear flow channel 3, and a plurality of openings 6 and an interface 7 connected to the secondary flow channel.

[0032] More specifically, the number of the plug parts 10 protruding from the body 4 matches the number of the openings 6. When the plug assembly 2 is matched with the plate body 1, part of the plug part 10 enters the linear flow channel 3, thereby achieving an effective connection between the linear flow channel 3 and the secondary flow channel.

[0033] In this embodiment, the plug 5 is used to detachably seal the opening 6 on the body 4. By adjusting the number of the plugs 5 and the matching relationship with different openings 6, the operation of a specific linear flow channel 3 can be selectively controlled, thereby increasing the flexibility of the system.

[0034] It should be understood that the plug assembly 2 is detachably fixed to the end of the plate body 1 by bolts, which is easy to install and disassemble, and convenient for future maintenance and repair.

[0035] As a further description of this embodiment, in the two plug assemblies 2, the interface 7 of one is used as a liquid inlet, and the interface 7 of the other is used as a liquid outlet. The liquid inlet and the liquid outlet are respectively connected to an external circulating liquid cooling device to realize circulating liquid supply to the linear flow channel 3 in the plate body 1, so as to efficiently cool the battery module.

[0036] On the basis of the above structure, when part of the straight flow channel 2 is damaged or leaking, the above structural design allows the operator to quickly switch the flow channel to maintain the normal operation of the cooling system, while improving the flexibility and maintainability of use.

[0037] Specifically, first, the operator needs to identify which one or several linear flow channels 2 are damaged or leaking. This can be done through observation, pressure testing, or system monitoring software. Once the damaged flow channels are identified, the operator will take measures to isolate these flow channels to prevent the cooling medium from continuing to pass through these damaged parts.

[0038] More specifically, each plug assembly 2 includes a plurality of detachable plugs 5, which can close the opening 6 provided on the body 4, and further close the corresponding linear flow channel 3 in the secondary flow channel. When the linear flow channel 3 is found to be damaged, the operator can add or adjust the plugs 5 by disassembling the corresponding plug assembly 2, and install or adjust the position of the plug 5 corresponding to the damaged flow channel to achieve the closure of the damaged flow channel.

[0039] Once the damaged linear flow channel is successfully isolated, the operator can reconfigure the fluid supply path of the remaining normal flow channel according to the cooling needs of the system. This is achieved by adjusting the unsealed openings in the plug assembly to ensure that the cooling medium circulates through the undamaged linear flow channel, thereby maintaining normal cooling of the battery module.

[0040] Through the above steps, even if part of the straight flow channel 2 is damaged, the liquid cooling plate can quickly switch the flow channel to achieve rapid recovery of the cooling function. This design not only reduces the system downtime caused by the damaged flow channel, but also improves the reliability and service life of the entire cooling system.

[0041] It is understandable that the detachable design of the plug assembly 2 makes it easier and faster to repair and replace the damaged flow channel. Maintenance personnel can easily remove the plug assembly 2 and repair or replace the damaged linear flow channel 3 without large-scale disassembly of the entire liquid cooling plate system, which greatly reduces maintenance costs and time.

[0042] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
