This invention supports and fixes both ends of the support frame between the top and bottom walls. The two ends of the support frame respectively abut against or are directly fixed to the top and bottom walls, which, while supporting the battery modules, also enhances the stability of the container body. Furthermore, in this embodiment, two separate, relatively spaced support frames are used within the energy storage spaces to form a group to support the battery modules, facilitating the installation and fixing of the support frames.

[0003] In the prior art, including the aforementioned patents, the use of refrigerated containers for battery storage requires stable and reasonable battery fixation while also ensuring effective heat dissipation to guarantee safe operation and lifespan. Traditional battery fixing devices suffer from problems such as simple structure, inconvenient installation and adjustment, and poor heat dissipation coordination, making it difficult to meet the fixing and heat dissipation requirements of battery packs in the complex environment of refrigerated containers. Therefore, it is essential to design a battery fixing device that is easy to install, flexibly adjustable, and has good heat dissipation performance. Utility Model Content

[0004] The purpose of this utility model is to provide a battery fixing device for liquid-cooled containers to solve the problems of simple structure, inconvenient installation and adjustment, and poor heat dissipation coordination mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery fixing device for a liquid-cooled container, comprising a container back panel, a side plate engaged with the side of the container back panel, a cover plate engaged with the top of the side plate, a cooling fan mounting groove on one side of the cover plate, an mounting channel fixedly connected to the front of the cover plate, an adjusting support assembly engaged with the inside of the mounting channel, a slide rail engaged with the inside of the container back panel, a pallet assembly engaged with the top of the slide rail, and a partition plate provided on the top of the pallet assembly.

[0006] Furthermore, the internal components of the adjustable support assembly include a support block, a limit buckle, and a telescopic sleeve. The support block is engaged with one side of the side plate, the limit buckle is fixedly connected to one end of the support block, and the telescopic sleeve is installed at the other end of the support block.

[0007] Furthermore, the telescopic sleeve is a two-end telescopic sleeve structure, and both ends of the telescopic sleeve are provided with support blocks and limit buckles.

[0008] Furthermore, the adjustment support assembly is provided in four sets, and the adjustment support assembly is connected to the upper and lower cover plates through four sets of mounting channels.

[0009] Furthermore, the tray assembly includes a base plate, an adjusting tray, a shaft support, a threaded rod, and a connecting sleeve. The top of the slide rail is engaged with the base plate, the top of the base plate is slidably mounted with the adjusting tray, the bottom of the adjusting tray is fixedly connected with the connecting sleeve, the top of the base plate is mounted with the shaft support, and the shaft support is threadedly connected with a threaded rod.

[0010] Furthermore, the adjusting tray is provided with T-shaped guide rails on both sides that are adapted to slide with the base plate, and one end of the threaded rod extends out of the base plate and is connected to a manual knob.

[0011] Furthermore, the partition has a pre-embedded liquid-cooled copper pipe, and both ends of the copper pipe extend out of the partition and are equipped with quick-connect connectors. The surface of the partition has a guide groove adapted to the heat dissipation fins of the battery module, and the partition is made of aluminum alloy composite thermally conductive plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the battery fixing device for liquid-cooled containers is reasonable and has the following advantages: (1) The adjustment support component of the device adopts a modular design. Its core component, the telescopic sleeve, achieves length adjustment through a three-level nested structure. The sleeve has a built-in high-precision hydraulic locking mechanism. After the adjustment is completed, the conical wedge block can be locked by rotating the external knob to ensure the axial bearing error of the support structure under full load conditions. The bottom of the adjustment tray of the pallet assembly is equipped with a threaded rod. The operator can drive the threaded rod to rotate by hand using a torque wrench. With the help of the dial displacement indicator, the X / Y axis can be finely adjusted in both directions. This composite adjustment mechanism enables the device to accurately adapt to the full range of battery modules. By replacing the special positioning clamp, it can also be compatible with battery products of different packaging forms such as square, soft pack, and cylindrical, effectively improving the engineering application versatility of the equipment. (2) The components of the device are connected by snap-fit ​​and meshing, which reduces the use of bolts and other connecting parts. The installation and disassembly process is simple and convenient, which reduces the installation difficulty and labor intensity and improves the installation efficiency. The four sets of adjustment support components support and limit the battery module from multiple directions. The T-shaped guide rail of the tray assembly ensures the stability of the sliding of the adjustment tray, so that the battery module can be stably fixed in the device, effectively avoiding the shaking and displacement of the battery module. (3) The utility model forms a highly efficient and coordinated heat dissipation system by using a heat dissipation fan and liquid-cooled copper pipe installed later. The heat dissipation fan adopts an axial flow fan structure and is equipped with a variable frequency speed control module. The dual air intake design accelerates air convection and forms a stable heat dissipation air duct inside the device. The liquid-cooled copper pipe adopts a serpentine layout with built-in spiral guide vanes. Combined with low viscosity coolant, it effectively improves heat exchange efficiency. The surface of the separator is precisely machined with honeycomb-shaped guide grooves. This biomimetic structure greatly optimizes the heat exchange path. At the same time, the separator is made of aluminum alloy composite thermally conductive plastic material. The aluminum alloy thermally conductive layer is combined with high-strength engineering plastic through a special co-extrusion process. Compared with traditional plastic separators, the heat transfer efficiency is improved by many times. Through this heat dissipation system, the heat generated by the battery module during operation can be quickly discharged, ensuring that the battery operating temperature is always maintained in the ideal range, significantly reducing the risk of battery capacity decay due to overheating, and effectively extending the service life of the battery module.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , 5 The present invention provides a technical solution as follows: Example 1: A battery fixing device for a liquid-cooled container includes a container back panel 1, a side panel 2 that is snapped onto the side of the container back panel 1, a cover plate 3 that is engaged with the top of the side panel 2, a cooling fan mounting groove 4 that is opened on one side of the cover plate 3, an mounting channel 5 that is fixedly connected to the front of the cover plate 3, an adjusting support assembly 6 that is snapped onto the inside of the mounting channel 5, a slide rail 7 that is snapped onto the inside of the container back panel 1, a pallet assembly 8 that is engaged with the top of the slide rail 7, and a partition 9 that is provided on the top of the pallet assembly 8. Furthermore, the adjusting support assembly 6 consists of a support block 601, a limiting buckle 602, and a telescopic sleeve 603. The support block 601 is engaged with one side of the side plate 2, providing support and positioning for the entire adjusting support assembly 6. One end of the support block 601 is fixedly connected to the limiting buckle 602, which restricts the telescopic range of the telescopic sleeve 603 to prevent excessive extension. The other end of the support block 601 is fitted with the telescopic sleeve 603, which is a two-end telescopic sleeve structure, with support blocks 601 and limiting buckles 602 at both ends. The adjusting support assembly 6 has four sets, connected to the upper and lower cover plates 3 via four sets of mounting channels 5. These four sets of adjusting support assemblies 6 support the internal structure of the device from different directions, improving the overall stability of the device. Furthermore, a slide rail 7 is engaged with the inner side of the container back panel 1. The slide rail 7 provides guidance for the movement of the pallet assembly 8. The top of the slide rail 7 is engaged with the pallet assembly 8, which is used to carry the battery module. The pallet assembly 8 includes a base plate 801, an adjusting tray 802, a shaft support 803, a threaded rod 804, and a connecting sleeve 805. The top of the slide rail 7 is engaged with the base plate 801, which provides the mounting base for the other components of the pallet assembly 8. The adjusting tray 802 is slidably mounted on the top of the base plate 801. The adjusting tray 802 is used to directly place the battery module. T-shaped guide rails are provided on both sides of the adjusting tray 802 to slide smoothly on the base plate 801. The T-shaped guide rails can ensure the stability of the adjusting tray 802 when sliding on the base plate 801 and prevent deviation.

[0017] Furthermore, a connecting sleeve 805 is fixedly connected to the bottom of the adjusting tray 802, and a shaft support 803 is installed on the top of the base plate 801. A threaded rod 804 is threadedly connected inside the shaft support 803. One end of the threaded rod 804 extends out of the base plate 801 and is connected to a manual knob. By rotating the manual knob, the threaded rod 804 can be rotated inside the shaft support 803. Since the threaded rod 804 cooperates with the connecting sleeve 805, it drives the adjusting tray 802 to slide on the base plate 801, thereby adjusting the position of the adjusting tray 802 to adapt to the placement requirements of battery modules of different sizes. Furthermore, a partition 9 is provided on the top of the tray assembly 8. Liquid-cooled copper pipes are pre-embedded inside the partition 9. Both ends of the copper pipes extend out of the partition 9 and are equipped with quick-connect fittings. The quick-connect fittings facilitate the connection between the partition 9 and the liquid cooling system. Through the flow of coolant in the liquid-cooled copper pipes, the heat generated by the battery module can be quickly removed.

[0018] The surface of the separator 9 is provided with a flow channel that is compatible with the heat dissipation fins of the battery module. The flow channel can guide the flow path of the coolant and improve the heat dissipation efficiency. The separator 9 is made of aluminum alloy composite thermally conductive plastic. This material not only has good thermal conductivity, which can quickly transfer the heat of the battery module to the liquid cooling copper pipe, but also has a certain structural strength, which can provide a certain support for the battery module.

[0019] Working principle: In use, firstly, during the operation of the battery fixing device for the liquid-cooled container, the battery module is placed on the adjusting tray 802 of the tray assembly 8. By turning the manual knob, the threaded rod 804 is driven to rotate. Under the action of the threaded transmission, the adjusting tray 802 slides along the T-shaped guide rail of the bottom plate 801, thereby realizing the fine adjustment of the position of the battery module to ensure good contact between the battery module and the separator 9. Secondly, the telescopic sleeve 603 of the adjusting support component 6 can be extended and retracted according to the size of the battery module and the installation requirements. The four sets of adjusting support components 6 support and limit the battery module from different directions to prevent the battery module from shaking and shifting during transportation or use, thus ensuring the stable fixation of the battery module. Finally, the cooling fan operates in the cooling fan mounting slot 4, accelerating the airflow inside the container. At the same time, the liquid-cooled copper pipe inside the partition 9 is connected to the liquid cooling system. The coolant circulates in the liquid-cooled copper pipe and exchanges heat with the heat dissipation fins of the battery module through the guide groove on the surface of the partition 9, quickly removing the heat generated by the battery module during operation, thus achieving efficient heat dissipation of the battery module.
