Description

Technical Field

[0001] This utility model belongs to the field of energy storage battery pack technology, specifically an energy storage liquid cooling plate that improves load-bearing performance. Background Technology

[0002] Liquid cooling plates are a crucial component of energy storage batteries, serving to support the battery cells and dissipate heat. They are widely used in applications requiring large-scale energy storage and release, such as energy storage power stations, industrial energy storage systems, data center energy storage, and portable energy storage devices. Because liquid cooling plates need to support a large number of battery cells, their structural load-bearing capacity is critical; therefore, optimization of the liquid cooling plate structure is necessary. Currently, most energy storage liquid cooling plates employ a frame-beam structure in conjunction with battery cell modules, resulting in complex manufacturing processes and long lead times.

The front and rear sealing unit modules connect and seal the internal flow channels of the aluminum extruded cooling plate, forming a sealed liquid cooling circuit. The design of the front and rear sealing unit modules meets the installation requirements of the battery pack cover while reducing the amount of aluminum extruded cooling plate material used, thereby lowering manufacturing costs. Two parallel load-bearing base supports are installed at the bottom of the aluminum extruded cooling plate, acting as equivalent external reinforcing beams. The applicability of this invention is not affected by the product's flow channel structure and can be applied to products with different flow channel structures.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] Example:

[0038] A type of energy storage liquid-cooled plate with improved load-bearing capacity, such as Figure 1-12 As shown, it includes an aluminum extruded cold plate 1, a front sealing unit module 3 at the front end of the aluminum extruded cold plate 1, a rear sealing unit module 4 at the rear end of the aluminum extruded cold plate 1, several embedded crossbeams 2 at the top of the aluminum extruded cold plate 1, and several load-bearing base supports 5 at the bottom of the aluminum extruded cold plate 1.

[0039] In one possible implementation, the aluminum extruded cold plate 1 is welded from two symmetrical sub-cold plates, and its top is provided with a CNC-machined embedded crossbeam mounting slot. Both sides of the aluminum extruded cold plate 1 are provided with battery pack cover sealing and fixing holes for installing rivet nuts 35.

[0040] In one possible implementation, the embedded crossbeam 2 has a flow channel groove for connecting and sealing the internal flow channel of the aluminum extruded cold plate 1. The embedded crossbeam 2 also has a battery cell guard plate fixing hole, which is embedded with a steel wire thread sleeve 9.

[0041] In one possible implementation, the embedded crossbeam 2 is an equivalent hidden beam, which is embedded and fixed inside the aluminum extruded cold plate 1 to improve the load-bearing performance of the aluminum extruded cold plate 1.

[0042] In one possible implementation, both the front-end sealing unit module 3 and the rear-end sealing unit module 4 are spliced ​​and welded to the aluminum extruded cold plate 1 and fixed by rivet nuts 35. The front-end sealing unit module 3 includes a front-end sealing unit 31. Both ends of the top of the front-end sealing unit 31 are provided with inlet and outlet water nozzles 32 for injecting and extracting coolant. The inlet and outlet water nozzles 32 are fixed to the front-end sealing unit 31 by welding. The inner sides of both ends of the front-end sealing unit 31 are sealed by inner sealing plates 33, and the outer sides are sealed by outer sealing plates 34. Both inner sealing plates 33 and outer sealing plates 34 are fixed to the front-end sealing unit 31 by welding. The rear-end sealing unit module 4 includes a rear-end sealing unit 41.

[0043] In one possible implementation, the load-bearing base 5 includes a mounting pad 6, the top of which is provided with a supporting sheet metal 7 and fixed by fixing bolts 8. The mounting pad 6 is fixed to the reserved mounting slot of the aluminum extruded cold plate 1 by argon arc welding. The mounting pad 6 is provided with threaded holes, and the supporting sheet metal 7 and the mounting pad 6 are provided with corresponding mounting through holes at the connection point. The mounting pad 6 and the supporting sheet metal 7 are connected by fixing bolts 8.

[0044] Example 2:

[0045] Figure 1 A schematic diagram of an energy storage liquid cooling plate structure with a load-bearing base, an embedded crossbeam structure, and a unitized sealing module, provided for this utility model. (Reference) Figure 1 A liquid-cooled energy storage plate with a load-bearing base, an embedded crossbeam structure and a unitized sealing module specifically includes: an aluminum extruded cooling plate 1, an embedded crossbeam 2, a front sealing unit module 3, a rear sealing unit module 4 and a load-bearing base 5.

[0046] Specifically, such as Figure 1 As shown, the aluminum extruded cold plate 1 is composed of two symmetrical sub-cold plates welded together by friction stir welding. The sub-cold plates are designed with internal flow channels. The combination of extrusion molding and friction stir welding processes can effectively improve the flatness accuracy of the inner cavity of the aluminum extruded cold plate, while simplifying the processing steps, shortening the processing time, and effectively reducing manufacturing costs.

[0047] Specifically, in combination Figure 1 , Figure 3 and Figure 9 As shown, the aluminum extruded cooling plate 1 has a battery pack cover sealing and fixing hole, and a rivet nut 35 is installed in the sealing and fixing hole. The aluminum extruded cooling plate 1 is CNC machined with mounting slots, and the embedded crossbeam 2 is fixed in the mounting slot by welding. The embedded crossbeam 2 is machined with battery guard plate mounting holes, and steel wire thread sleeves 9 are embedded in the mounting holes. The battery guard plate is installed in conjunction to pre-tighten and limit the battery cells. The guard plate is fixed through the fixing holes on the embedded crossbeam 2. The design of the embedded crossbeam 2 reduces the number of parts such as the battery cell module end plate, module fixing beam, and battery steel strip, eliminating the need for a module production line, simplifying the processing steps, and reducing production and processing costs. At the same time, the embedded crossbeam 2 is also equivalent to adding an internal hidden beam to the aluminum extruded cooling plate 1, further improving the overall load-bearing capacity of the liquid cooling plate.

[0048] Specifically, in combination Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, both the front-end sealing unit module 3 and the rear-end sealing unit module 4 are integral extruded profile structures used to connect and seal the internal flow channels of the aluminum extruded cooling plate 1, forming a sealed liquid cooling circuit. The front and rear sealing unit modules are manufactured as follows: Figure 4 and Figure 7 The groove shown is formed by processing aluminum extruded cold plate 1 as follows. Figure 9 The bosses shown are assembled with a clearance fit and then welded together. Inlet and outlet water nozzles 32 are located on both sides of the front sealing unit module 3 for coolant injection and extraction, and are welded to the front sealing unit 31. The front sealing unit module 3 has an internal cavity structure, sealed by welding between an inner sealing plate 33 and an outer sealing plate 34. The front and rear sealing unit modules also have battery pack cover sealing and fixing holes, in which rivet nuts 35 are installed to fix and seal the battery pack cover. The design of the front and rear sealing unit modules, while meeting the battery pack cover installation requirements, significantly reduces the amount of aluminum extruded cold plate used, achieving weight reduction of the liquid cooling plate and lowering manufacturing costs.

[0049] Specifically, such as Figure 2 and Figure 10 As shown, the load-bearing base 5 consists of a mounting plate 6, a supporting sheet metal 7, and fixing bolts 8. The mounting plate 6 is fixed by welding, and the supporting sheet metal 7 is fixed to the mounting plate 6 by the fixing bolts 8. The two load-bearing bases 5 are installed in parallel on the bottom surface of the aluminum extruded cold plate 1, which is equivalent to adding two external reinforcing beams and improving the load-bearing performance of the liquid cooling plate.

[0050] Example 3:

[0051] Unlike Example 2, as follows: Figure 11 and Figure 12 As shown, the load-bearing base 5 in this embodiment is a standard aluminum profile structure. Specifically, two load-bearing bases 5 are evenly distributed parallel to each other on the bottom surface of the aluminum extruded cold plate 1 and are fixed to the aluminum extruded cold plate 1 by welding. The two load-bearing bases 5 are equivalent to adding two external reinforcing beams to the aluminum extruded cold plate 1, improving the load-bearing performance of the liquid cooling plate. The use of welding technology for the load-bearing bases 5 can reduce the number of parts, simplify the production process, and reduce production costs.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
