Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, and more specifically, to an energy storage liquid cooling plate device with an integrated flanged box structure. Background Technology

[0002] With the rapid development of new energy technologies, the power density and integration of energy storage devices are constantly improving. The large amount of heat generated during their operation has become a key factor affecting the performance and lifespan of the equipment. As a highly efficient heat dissipation component, liquid cooling plates are widely used in the thermal management system of energy storage devices. They remove heat through the circulation of coolant in the flow channels, thereby achieving temperature control of the core components of energy storage.

[0003] Existing liquid-cooled plate devices mostly adopt a structure with fins built into the lower cover plate. The fins are arranged along the flow channel and guide fins are set at the turning points to ensure the flow efficiency and heat dissipation uniformity of the coolant. However, in practical applications, the operating environment of energy storage devices is complex. The liquid-cooled plate not only needs to meet the requirements of efficient heat dissipation, but also needs to withstand the installation stress during equipment assembly, the vibration and impact during operation, and the internal pressure generated by the circulation of coolant. The structural strength of existing liquid-cooled plate devices is often difficult to achieve simultaneously. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose an energy storage liquid cooling plate device with an integrated flanged box structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An energy storage liquid-cooled plate device with an integrated flanged box structure includes fins and a lower cover plate. The fins are disposed inside the lower cover plate and are neatly arranged along the flow channel of the lower cover plate. Guide fins are provided at the position where the flow channel changes direction to form a liquid-cooled plate. An upper cover plate is assembled and fitted on the upper part of the liquid-cooled plate. A connector connected to the water inlet of the liquid-cooled plate is provided on the upper part of the upper cover plate. Multiple sets of crossbeams are also provided on the upper part of the upper cover plate, and the crossbeams are also connected to the liquid-cooled plate. A support plate is provided below the liquid-cooled plate. The surface of the support plate is connected to the liquid-cooled plate. A flange is formed around the perimeter of the support plate, which wraps around the liquid-cooled plate and is connected to both.

[0007] Furthermore, the above solution includes a space between two adjacent flanges to promote air circulation, aid heat dissipation, and reduce the overall structural weight, thereby improving the ease of assembly and performance of the device.

[0008] Furthermore, in the above solution, the liquid cooling plate is connected and fixed to the crossbeam by a press-fitting method through the preset mounting holes. The crossbeam is matched with the press-fitting parts reserved on the upper cover plate through the opened fixed holes and is installed by pre-tightening screws.

[0009] Furthermore, the above solution involves integrally welding the liquid cooling plate, top cover plate, crossbeam, and support plate using a tunnel furnace brazing method to ensure a firm weld for each component.

[0010] Furthermore, the above solution includes four sets of crossbeams arranged along the width of the upper cover plate, with two sets arranged side by side in the middle of the upper cover plate and the other two sets symmetrically arranged at the edge of the upper cover plate. This further enhances the structural strength and deformation resistance of the device, ensuring that all components remain firmly connected during use.

[0011] Furthermore, the above solution involves using a smooth plate or forming a textured structure on the pallet to ensure product strength.

[0012] Furthermore, the above solution includes openings around the pallet for easy maintenance.

[0013] Furthermore, the above solution includes a reinforcing rib at the bottom of the tray and a drainage hole at the position of the reinforcing rib to facilitate the cleaning of water accumulation between the tray and the liquid cooling plate caused by water testing. It can also reduce product weight and heat penetration during welding.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, through the combined design of the top cover plate, crossbeam and flanged support plate, enhances the structural strength and deformation resistance while ensuring basic heat dissipation function, improves assembly reliability and sealing, achieves optimized heat dissipation efficiency and lightweight design, and is easy to assemble, highly adaptable, and takes into account both functionality and economy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0022] See attached document Figure 1 - Appendix Figure 4 As shown, an energy storage liquid cooling plate device with an integrated flanged box structure includes fins 1 and a lower cover plate 11. The fins 1 are disposed inside the lower cover plate 11 and are neatly arranged along the flow channel direction of the lower cover plate 11. Guide fins 12 are provided at the position where the flow channel changes direction to form a liquid cooling plate. This structural method is a conventional technical means, and therefore will not be described in detail here. The improvement of this utility model lies in that an upper cover plate 2 is assembled and fitted above the liquid cooling plate, and an inlet for the liquid cooling plate is provided above the upper cover plate 2. Connected joint 3; In addition, multiple sets of crossbeams 4 are provided above the upper cover plate 2, and the crossbeams 4 are also connected to the liquid cooling plate; Among them, a support plate 5 is provided below the liquid cooling plate, the surface of the support plate 5 is connected to the liquid cooling plate, and a flange 51 is formed around the perimeter of the support plate 5. The flange 51 wraps around the liquid cooling plate and is connected to both of them, and a gap space 52 is formed between two adjacent flanges 51 to promote air circulation, assist heat dissipation, and reduce the overall structural weight, further improving the ease of assembly and performance of the device.

[0023] In the implementation of the above scheme, the liquid cooling plate is based on the conventional lower cover plate 11 with built-in forward flow channel fins 1 (including flow guide fins 12 at the turning point). The core improvement is that the upper cover plate 2 is aligned and fitted with the liquid cooling plate and a connector 3 connecting the water inlet is set. At the same time, multiple sets of crossbeams 4 connected to the liquid cooling plate are added above the upper cover plate 2 to enhance the structural stability. A support plate 5 is configured below. The surface and surrounding flanges 51 of the support plate 5 are connected to the liquid cooling plate. The overall design of the upper and lower cover plates 11, crossbeams 4 and support plate 5 with flanges 51 improves the structural strength and assembly reliability of the device while retaining the basic liquid cooling function.

[0024] Specifically, regarding the connection method of the liquid cooling plate, the upper cover plate 2, the crossbeam 4 and the support plate 5;

[0025] The liquid cooling plate is connected and fixed to the crossbeam 4 through the preset mounting holes using a press-fit method. The crossbeam 4 is matched with the pre-reserved press-fit parts of the upper cover plate 2 through the fixed holes and is installed using screws. Before installation, welding plates are placed between the crossbeam 4 and the upper cover plate 2. Finally, the liquid cooling plate, upper cover plate 2, crossbeam 4 and support plate 5 are welded together by tunnel furnace brazing to ensure that each component is firmly welded.

[0026] Among them, refer to the appendix Figure 3 As shown, there are four sets of crossbeams 4, which are arranged along the width of the upper cover plate 2. Two sets are arranged side by side in the middle of the upper cover plate 2, and the other two sets are symmetrically arranged at the edge of the upper cover plate 2. This design allows the force to be transmitted more evenly in the structure, greatly enhancing the overall stability of the connection between the upper cover plate 2 and the liquid cooling plate. At the same time, the connection methods of riveting, screw pre-tightening and tunnel furnace brazing further improve the structural strength and deformation resistance of the device, ensuring that all components are always firmly connected during use.

[0027] In addition, during implementation, the pallet 5 is made of a smooth plate or has a textured structure to ensure product strength; the pallet 5 has openings around its perimeter for easy maintenance (not shown in the figure); the bottom of the pallet 5 has reinforcing ribs (not shown in the figure), and drainage holes (not shown in the figure) are provided at the position of the reinforcing ribs, which facilitates the cleaning of water accumulation between the pallet 5 and the liquid cooling plate caused by water testing, and can also reduce product weight and heat penetration and expansion during welding.
