Description

Technical Field

[0001] This invention relates to the field of battery liquid cooling plate housing technology, and more particularly to a reinforced frame-type battery liquid cooling plate housing structure and energy storage system. Background Technology

[0002] In containerized energy storage systems, the batteries inside generate heat during operation, which reduces their performance. To protect the batteries and reduce the heat dissipation, containerized energy storage systems provide flat-plate battery liquid cooling plate enclosures. The flat-plate battery liquid cooling plate enclosure consists of a liquid cooling plate surrounded by a frame structure. The frame structure is placed inside the container, and the batteries are housed within the frame structure, with the bottom of the batteries in direct contact with the liquid cooling plate.

[0003] In related technologies, the liquid-cooled plate housing has a crossbeam below the liquid-cooled plate, and the upper protrusion of the crossbeam and the lower protrusion formed by the cooling channel of the liquid-cooled plate are in surface contact, and the two are fixedly connected by rivets. However, such connection of the liquid-cooled plate and the crossbeam will cause leakage of the cooling medium in the liquid-cooled plate. Moreover, when the rivets are connected, the local stress generated around the rivets will cause perimeter deformation or cracking at the contact point between the liquid-cooled plate and the rivets, affecting the cooling effect of the liquid-cooled plate.

[0004] Therefore, there is an urgent need for a reinforced frame-type battery liquid cooling plate housing structure and energy storage system to solve the above problems. Summary of the Invention

[0005] One of the objectives of this invention is to provide a reinforced frame-type battery liquid cooling plate housing structure, which can prevent leakage of the cooling medium in the liquid cooling plate, ensure the cooling effect of the liquid cooling plate, and indirectly increase the contact area between the liquid cooling plate and the pressure-bearing beam, disperse and evenly distribute the stress between the liquid cooling plate and the pressure-bearing beam, reduce stress concentration in the liquid cooling plate, prevent cracking or deformation of the liquid cooling plate, and ensure the structural stability of the liquid cooling plate.

The load-bearing component includes two load-bearing members, which are connected at intervals along the width direction of the liquid cooling plate to the lower end face of the liquid cooling plate. Along the thickness direction of the liquid cooling plate, the thickness of the load-bearing member is greater than the thickness of the front load-bearing beam, the middle load-bearing beam, and the rear load-bearing beam.

[0010] As a preferred embodiment, the reinforced frame-type battery liquid cooling plate housing structure also includes: The upper frame assembly is fixedly connected to the upper end face of the liquid cooling plate.

[0011] As a preferred embodiment, the upper frame assembly has a sealing groove on the end face facing the liquid cooling plate, and a sealant is provided between the wall of the sealing groove and the upper end face of the liquid cooling plate.

[0012] As a preferred embodiment, the liquid cooling plate has a first fixing hole, and the reinforced frame-type battery liquid cooling plate housing structure also includes an electrical component fixing assembly. The electrical component fixing assembly includes an electrical component support and a clamping fixing member. The electrical component support has a second fixing hole with the same diameter as the first fixing hole. The electrical component support can be placed on the liquid cooling plate. The first fixing hole can communicate with the second fixing hole. The first end of the clamping fixing member abuts against the electrical component support, and the second end of the clamping fixing member passes through the first fixing hole and the second fixing hole and abuts against the liquid cooling plate, so that the electrical component support and the liquid cooling plate are clamped in the clamping fixing member.

[0013] As a preferred embodiment, the liquid cooling plate includes an upper plate and a lower plate. The upper plate is a flat plate structure. A portion of the lower plate protrudes downward to form a first flow channel and a second flow channel. The first flow channel is located at the end of the lower plate along its length. The upper plate can cover the lower plate to seal the first flow channel and the second flow channel to form a first liquid flow channel and a second liquid flow channel, respectively. The second liquid flow channel contains a cooling medium. The first liquid flow channel and the second liquid flow channel are not interconnected. A first fixing hole is opened on the upper plate and is connected to the first liquid flow channel.

[0016] To achieve this objective, the present invention adopts the following technical solution: An energy storage system includes an energy storage box, a support frame, and the aforementioned reinforced frame-type battery liquid cooling plate box structure. The energy storage box has an internal cavity, and the support frame is fixedly connected to the inner wall of the internal cavity. The reinforced frame-type battery liquid cooling plate box structure can be placed on the support frame.

[0017] The beneficial effects of this invention are: This invention provides a reinforced frame-type battery liquid-cooled plate housing structure, including a liquid-cooled plate, a transition fastener, and a pressure-bearing beam assembly. The pressure-bearing beam assembly includes a front pressure-bearing beam, a middle pressure-bearing beam, and a rear pressure-bearing beam. Along the length of the liquid-cooled plate, the middle pressure-bearing beam is located between the front and rear pressure-bearing beams. The front and rear pressure-bearing beams are fixedly connected to the lower end face of the liquid-cooled plate. The middle pressure-bearing beam includes a beam body, a first protrusion, and multiple second protrusions. In the reinforced frame-type battery liquid-cooled plate housing structure, the transition fastener serves as the core connector between the liquid-cooled plate and the middle pressure-bearing beam. It is fixedly connected to the bottom wall of a first groove located in the middle of the lower end face of the liquid-cooled plate. Simultaneously, the first protrusion on the beam body is fixedly connected to the transition fastener, allowing the middle pressure-bearing beam to support the liquid-cooled plate through the transition fastener. The presence of the transition fastener prevents the middle pressure-bearing beam from being directly connected to the liquid-cooled plate, thus preventing liquid... The leakage of cooling medium in the cold plate ensures the cooling effect of the liquid cooling plate and indirectly increases the contact area between the liquid cooling plate and the pressure-bearing beam, dispersing and evenly distributing the stress between the liquid cooling plate and the pressure-bearing beam, reducing stress concentration in the liquid cooling plate, and preventing cracking or deformation of the liquid cooling plate. In addition, multiple second protrusions are bonded to the bottom wall of the first groove corresponding to the lower end face of the liquid cooling plate, which further improves the connection stability between the pressure-bearing beam and the liquid cooling plate, and disperses the stress through multi-point bonding, avoiding stress concentration between the first protrusion and the transition connector, and preventing the liquid cooling plate connected to the transition connector from deforming due to stress concentration, thereby affecting the cooling effect of the liquid cooling plate. At the same time, the fixed connection between the pressure-bearing front beam and the pressure-bearing rear beam and the lower end face of the liquid cooling plate, together with the pressure-bearing beam, forms the bottom support for the liquid cooling plate, reducing stress concentration in the liquid cooling plate and ensuring the structural stability of the liquid cooling plate.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] This embodiment provides a reinforced frame-type battery liquid cooling plate housing structure, such as Figures 1-4 As shown, the assembly includes a liquid-cooled plate 1, a transition fastener 2, and a pressure-bearing beam assembly 3. The lower end face of the liquid-cooled plate 1 has multiple protrusions 11, spaced apart along the width direction and extending along the length direction of the liquid-cooled plate 1. A first groove 12 is formed between two adjacent protrusions 11. The upper end face of the liquid-cooled plate 1 is used to place a battery. The transition fastener 2 is fixedly connected to the bottom wall of the first groove 12 located in the middle of the lower end face of the liquid-cooled plate 1. The pressure-bearing beam assembly 3 includes a front pressure-bearing beam 31, a middle pressure-bearing beam 32, and a rear pressure-bearing beam 33. Along the length direction of the liquid-cooled plate 1, the middle pressure-bearing beam 32 is located between the front pressure-bearing beam 31 and the rear pressure-bearing beam 33. The front pressure-bearing beam 31 and the rear pressure-bearing beam 33 are fixedly connected to the liquid-cooled plate 1. The lower end face of the cold plate 1, the pressure-bearing beam 32 includes a beam body 321, a first protrusion 322 and a plurality of second protrusions 323. The beam body 321 extends along the width direction of the liquid-cooled plate 1, and its two ends are fixedly connected to the lower end face of the liquid-cooled plate 1 by rivets. The first protrusion 322 and the plurality of second protrusions 323 are disposed on the surface of the beam body 321 facing the lower end face of the liquid-cooled plate 1. The first protrusion 322 and the plurality of second protrusions 323 are arranged at intervals along the extension direction of the beam body 321, and the first protrusion 322 is located in the middle of two adjacent second protrusions 323. The first protrusion 322 is fixedly connected to the transition fastener 2, and the second protrusion 323 is bonded to the bottom wall of the corresponding first groove 12.

[0026] In the reinforced frame-type battery liquid cooling plate housing structure, the transition fastener 2 serves as the core connector between the liquid cooling plate 1 and the pressure-bearing central beam 32. It is fixedly connected to the bottom wall of the first groove 12 located in the middle of the lower end face of the liquid cooling plate 1. Simultaneously, the first protrusion 322 on the central beam body 321 is fixedly connected to the transition fastener 2, allowing the pressure-bearing central beam 32 to support the liquid cooling plate 1 via the transition fastener 2. The presence of the transition fastener 2 prevents the pressure-bearing central beam 32 from being directly connected to the liquid cooling plate 1, thus preventing leakage of the cooling medium in the liquid cooling plate 1 and ensuring the cooling effect of the liquid cooling plate 1. It also indirectly increases the contact area between the liquid cooling plate 1 and the pressure-bearing central beam 32, dispersing and evenly distributing the stress between them, and reducing... This design reduces stress concentration in the liquid cooling plate 1, preventing cracking or deformation. Multiple second protrusions 323 are bonded to the bottom wall of the first groove 12 corresponding to the lower end face of the liquid cooling plate 1. This further enhances the connection stability between the pressure-bearing beam 32 and the liquid cooling plate 1. Furthermore, the multi-point bonding disperses stress, preventing stress concentration between the first protrusion 322 and the transition fastener 2. This prevents deformation of the liquid cooling plate 1 connected to the transition fastener 2 due to stress concentration, thus avoiding any impact on its cooling effect. Simultaneously, the fixed connection between the pressure-bearing front beam 31 and the pressure-bearing rear beam 33 and the lower end face of the liquid cooling plate 1, together with the pressure-bearing beam 32, forms a bottom support for the liquid cooling plate 1, reducing stress concentration and ensuring structural stability. It should be noted that both ends of the pressure-bearing front beam 31, the beam body 321, and the pressure-bearing rear beam 33 are fixedly connected to the lower end face of the liquid cooling plate 1 using first blind rivets.

[0027] Specifically, in this embodiment, four second protrusions 323 are provided. In other embodiments, two, three, five, or six second protrusions 323 are provided, etc. When an even number of second protrusions 323 are provided, the first protrusion 322 is located in the middle position, and the second protrusions 323 on both sides are symmetrically arranged with respect to the first protrusion 322. When an odd number of second protrusions 323 are provided, the first protrusion 322 is located in the middle position, and the number of second protrusions 323 on one side is one less than the number of second protrusions 323 on the other side.

[0028] Specifically, such as Figures 2-4As shown, in this embodiment, the transition fastener 2 is a hollow square tube, and the hollow square tube is adapted to the first groove 12. The hollow square tube not only ensures the connection between the central beam body 321 and the liquid cooling plate 1, but also indirectly ensures the supporting strength of the pressure-bearing central beam 32 on the liquid cooling plate 1. Furthermore, the hollow design enhances the energy absorption and vibration reduction effect of the transition fastener 2. When the battery is placed on the liquid cooling plate 1, the transition fastener 2 can absorb part of the impact force, reducing the rigid impact between the liquid cooling plate 1 and the pressure-bearing central beam 32, and preventing deformation of the liquid cooling plate 1. In other embodiments, the transition fastener 2 is a solid plate or a frame structure, etc. No restrictions are placed here.

[0029] Specifically, such as Figures 2-4 As shown, in this embodiment, the transition fastener 2 is brazed to the lower end face of the liquid cooling plate 1. In other embodiments, the transition fastener 2 is bonded to the lower end face of the liquid cooling plate 1, or snap-fitted, etc. No limitation is made here.

[0030] Specifically, such as Figure 4 As shown, in this embodiment, the central beam body 321 and the transition fastener 2 are fixedly connected by a second pop rivet 7. In other embodiments, the central beam body 321 and the transition fastener 2 are fixedly connected by a first fastening bolt, etc. No limitations are imposed here.

[0031] Optionally, such as Figure 2 As shown, multiple pressure-bearing beams 32 are provided, spaced apart along the length of the liquid-cooled plate 1. The arrangement of multiple pressure-bearing beams 32 evenly distributes the weight of the battery placed on the liquid-cooled plate 1 from the center of its lower end face, avoiding concentrated stress and bending that could cause deformation of the liquid-cooled plate 1. This reduces the risk of localized deformation and ensures the supporting and cooling effect of the liquid-cooled plate 1 on the battery. In this embodiment, three pressure-bearing beams 32 are provided. In other embodiments, one, two, four, or five pressure-bearing beams 32 may be provided, etc. No limitation is made here.

[0032] Optionally, such as Figures 2-5As shown, the central beam body 321 is in the shape of a corrugated steel tile, so that the central beam body 321 forms a third protrusion 3211 and a second groove 3212 arranged at intervals and connected along the length direction of the liquid cooling plate 1. The bottom wall of each second groove 3212 forms a first protrusion 322 and a plurality of second protrusions 323 facing the lower end face of the liquid cooling plate 1. The extension length of the transition fastener 2 in the first groove 12 is the same as the extension length of the central beam body 321 along the length direction of the liquid cooling plate 1. The corrugated steel tile-shaped central beam body 321 is composed of alternating third protrusions 3211 and second grooves 3212. Compared with a flat structure of the same thickness, the alternating concave-convex structure of the central beam body 321 reduces material costs and improves the deformation resistance of the central beam body 321, thus enhancing its support performance for the liquid cooling plate 1. Simultaneously, first protrusions 322 and multiple second protrusions 323 are provided on the bottom walls of the multiple second grooves 3212 of the alternating concave-convex structure of the central beam body 321, increasing the support capacity of the central beam body 321 and the liquid cooling plate 1. The contact area allows the central beam body 321 to switch from linear support to surface support of the liquid cooling plate 1, avoiding deformation of the liquid cooling plate 1 due to stress concentration in a single contact area. At the same time, the extension length of the transition fastener 2 in the first groove 12 is the same as the extension length of the central beam body 321 along the length direction of the liquid cooling plate 1, so that the first protrusions 322 on the bottom wall of the multiple second grooves 3212 are indirectly fixed to the liquid cooling plate 1 through the transition fastener 2, and support the weight of the liquid cooling plate 1 and the battery placed on it.

[0033] Optionally, in this embodiment, the middle beam body 321 is composed of four third protrusions 3211 and three second grooves 3212. In other embodiments, the middle beam body 321 is composed of three third protrusions 3211 and two second grooves 3212, or the middle beam body 321 is composed of five third protrusions 3211 and four second grooves 3212, etc. No limitation is made here.

[0034] Optionally, such as Figures 5-7As shown, the reinforced frame-type battery liquid cooling plate box structure also includes a load-bearing component 4, which is located between the pressure-bearing front beam 31 and the pressure-bearing middle beam 32 and / or between the pressure-bearing rear beam 33 and the pressure-bearing middle beam 32 and / or between two adjacent pressure-bearing middle beams 32. The load-bearing component 4 includes two load-bearing members 41, which are connected at intervals along the width direction of the liquid cooling plate 1 to the lower end face of the liquid cooling plate 1. Along the thickness direction of the liquid cooling plate 1, the thickness of the load-bearing member 41 is greater than the thickness of the pressure-bearing front beam 31, the thickness of the pressure-bearing middle beam 32 and the thickness of the pressure-bearing rear beam 33. Two spaced-apart load-bearing members 41 are connected to the lower end face of the liquid-cooled plate 1. Along the thickness direction of the liquid-cooled plate 1, the thickness of the load-bearing members 41 is greater than the thickness of the front load-bearing beam 31, the middle load-bearing beam 32, and the rear load-bearing beam 33. This ensures that when the liquid-cooled plate 1 is placed on the load-bearing platform, the load-bearing members 41 preferentially contact the load-bearing platform, avoiding wear on the middle load-bearing beam 321 caused by rigid contact between the middle load-bearing beam body 321 and the load-bearing platform. When the liquid-cooled plate 1 and the battery placed on it are placed flat... When stable, due to gravity, the liquid cooling plate 1 will cause slight deformation of the front pressure beam 31, the middle beam body 321, and the rear pressure beam 33 toward the bearing platform. This will eliminate the thickness difference between the load-bearing component 41 and the front pressure beam 31 and / or the middle beam body 321 and / or the rear pressure beam 33. The load-bearing front beam 31, the middle beam body 321, and the rear pressure beam 33 will still hold the battery in place with the bearing platform, providing support and ensuring the support strength of the liquid cooling plate 1 and the battery. It should be noted that the thickness of the front pressure beam 31, the middle beam body 321, and the rear pressure beam 33 are the same.

[0035] Specifically, such as Figure 5 and Figure 7 As shown, load-bearing components 4 are provided between the front load-bearing beam 31 and the middle load-bearing beam 32, between the rear load-bearing beam 33 and the middle load-bearing beam 32, and between two adjacent middle load-bearing beams 32. This arrangement, with load-bearing components 4 between adjacent load-bearing beams, can simultaneously prevent wear on the front load-bearing beam 31, the middle load-bearing beam 32, and the rear load-bearing beam 33.

[0036] Optionally, such as Figure 8 As shown, the reinforced frame-type battery liquid cooling plate housing structure also includes an upper frame assembly 5, which is fixedly connected to the upper end face of the liquid cooling plate 1. The upper frame assembly 5 and the liquid cooling plate 1 enclose a battery receiving cavity 51, in which the battery is placed. The upper frame assembly 5 and the battery receiving cavity 51 provide a stable installation position and foundation for the battery, ensuring the stability of the battery within the battery receiving cavity 51. Furthermore, the upper frame assembly 5, fixed to the upper end face of the liquid cooling plate 1, secures the liquid cooling plate 1 from above, improving the deformation resistance of the liquid cooling plate 1 and preventing deformation of the liquid cooling plate 1 due to the battery's own weight. Specifically, as... Figure 8As shown, the upper frame component 5 is a square frame structure formed by connecting two first rods and two second rods in sequence.

[0037] Specifically, the upper frame assembly 5 has a sealing groove on its end face facing the liquid cooling plate 1, and a sealant is provided between the wall of the sealing groove and the upper end face of the liquid cooling plate 1. The sealant allows it to be evenly filled in the gap between the upper frame assembly 5 and the liquid cooling plate 1 through the sealing groove, forming a sealing structure and improving the assembly sealing and fitting stability of the upper frame assembly 5 and the liquid cooling plate 1.

[0038] Optionally, such as Figures 8-11 As shown, the liquid cooling plate 1 has a first fixing hole 131. The reinforced frame-type battery liquid cooling plate housing structure also includes an electrical component fixing assembly 6. The electrical component fixing assembly 6 includes an electrical component support 61 and a clamping fixing member 62. The electrical component support 61 has a second fixing hole 611. The diameter of the second fixing hole 611 is the same as that of the first fixing hole 131. The electrical component support 61 can be placed on the liquid cooling plate 1. The first fixing hole 131 can communicate with the second fixing hole 611. The first end of the clamping fixing member 62 abuts against the electrical component support 61. The second end of the clamping fixing member 62 passes through the first fixing hole 131 and the second fixing hole 611 and abuts against the liquid cooling plate 1, so that the electrical component support 61 and the liquid cooling plate 1 are clamped in the clamping fixing member 62. The electrical component support 61 and the liquid cooling plate 1 are clamped together at both ends by the clamping fastener 62, without the need for additional welding or bonding. The assembly is convenient and detachable, and the operation is more efficient when replacing the electrical component support 61 during maintenance. Furthermore, the electrical component support 61 is directly integrated on the liquid cooling plate 1, without the need for additional mounting base, which simplifies the overall layout and improves the integration of the reinforced frame battery liquid cooling plate box structure.

[0039] Specifically, in this embodiment, the electrical component support 61 is a support plate. In other embodiments, the electrical component support 61 is a support frame, etc. No limitations are imposed here.

[0040] Optionally, such as Figures 7-11As shown, the liquid cooling plate 1 includes an upper plate 13 and a lower plate 14. The upper plate 13 is a flat plate structure. A portion of the lower plate 14 protrudes downward to form a first flow channel groove 141 and a second flow channel groove 142. The first flow channel groove 141 is located at the end of the lower plate 14 along its length. The upper plate 13 can cover the lower plate 14 so that the first flow channel groove 141 and the second flow channel groove 142 are respectively sealed to form a first liquid flow channel and a second liquid flow channel. Cooling medium is provided in the second liquid flow channel. The first liquid flow channel and the second liquid flow channel are not connected to each other. A first fixing hole 131 is opened in the upper plate 13 and is connected to the first liquid flow channel. The clamping and fixing member 62 is a U-shaped clamp. The electrical component support member 61 and the upper plate 13 can be clamped in the U-shaped clamp. In the above configuration, the first flow channel 141 is arranged at the end of the lower plate 14 and communicates with the first fixing hole 131. The second liquid flow channel is provided with cooling medium. The two channels do not interfere with each other, which not only ensures the independence of the cooling function, but also achieves the connection and adaptation with the electrical component support 61 through the U-shaped clamp in conjunction with the first fixing hole 131 and the second fixing hole 611, thus avoiding the airtightness problem of the liquid cooling plate 1.

[0041] Optionally, such as Figure 10 and Figure 11 As shown, the electrical component fixing assembly 6 also includes a locking member 63. One end of the locking member 63 passes sequentially through the first end of the clamping fixing member 62, the electrical component support member 61, the upper plate 13, and the second end of the clamping fixing member 62, and is fixedly connected to the second end of the clamping fixing member 62. The other end of the locking member 63 can abut against the first end of the clamping fixing member 62. When the U-shaped clamp abuts against and clamps the electrical component support member 61 and the upper plate 13, the locking member 63 fixes the position of the clamping fixing member 62 on the upper plate 13, thereby ensuring the position of the electrical component support member 61 on the upper plate 13.

[0042] Specifically, in this embodiment, the locking element 63 is a second fastening bolt. In other embodiments, the locking element 63 is a rivet or a pin, etc. No limitation is made here.

[0043] Specifically, such as Figures 8-10 As shown, the upper plate 13 has three first fixing holes 131, which are spaced apart along the width direction of the liquid cooling plate 1. The electrical component support 61 has three second fixing holes 611, which are also spaced apart along the width direction of the liquid cooling plate 1. The electrical component fixing assembly 6 includes three clamping fixing members 62, which abut against and clamp the electrical component support 61 and the upper plate 13 through the corresponding first fixing holes 131 and second fixing holes 611. The arrangement of multiple clamping fixing members 62 improves the reliability and stability of the connection between the electrical component support 61 and the upper plate 13.

[0044] This embodiment also provides an energy storage system, which includes an energy storage box, a support cluster, and a reinforced frame-type battery liquid-cooled plate box structure. The energy storage box has an internal cavity, and the support cluster is fixedly connected to the inner wall of the internal cavity. The reinforced frame-type battery liquid-cooled plate box structure can be placed on the support cluster. When the reinforced frame-type battery liquid-cooled plate box structure and the battery housed thereon are placed on the support cluster, the load-bearing component 41 first contacts the support cluster. Then, due to the gravity of the battery, the front beam 31, the middle beam body 321, and the rear beam 33 undergo slight deformation towards the bearing platform. This eliminates the thickness difference between the load-bearing component 41 and the front beam 31, the middle beam body 321, and the rear beam 33, providing stable support for the liquid-cooled plate 1 and the battery housed thereon, and enabling stable cooling and heat dissipation of the battery, thus improving the stability and reliability of the energy storage system.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
