Description

Technical Field

[0001] This utility model relates generally to the technical field of containers, and more specifically to a partition wall assembly and a liquid-cooled energy storage box. Background Technology

[0002] Liquid-cooled energy storage boxes typically consist of a battery compartment, a liquid-cooling compartment, and an equipment compartment, with each part separated by partition walls. These partition walls are required to provide thermal insulation, waterproofing, and dustproofing.

[0003] To ensure heat dissipation, the liquid cooling chamber is usually not sealed to the outside world. Rainwater can enter the liquid cooling chamber, but water is not allowed to enter the battery chamber and equipment chamber. Therefore, the partition walls between the liquid cooling chamber and the battery chamber, and between the liquid cooling chamber and the equipment chamber, have particularly high requirements for waterproofing.

[0004] Currently, existing container sheet metal partitions are composed of multiple sheet metal parts. The joints between the sheet metal parts are sealed by welding and glue, which is not airtight and the sealing performance is easily affected by glue delamination after long-term use. Utility Model Content

[0005] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0008] An outer sealing plate is arranged on one side of the bent plate along the thickness direction. Along the splicing direction of the wall panel component perpendicular to the thickness direction, the first side of the outer sealing plate protrudes from the first bent edge, and the second side of the outer sealing plate overlaps with the second bent edge and forms a stepped groove with the second bent edge.

[0009] In this arrangement, at least two of the wall panel components are arranged along the splicing direction, and the first side of the outer sealing plate of at least one of the wall panel components is fitted to the stepped groove formed by the adjacent wall panel component.

In adjacent wall panel components, the first side edge of the outer sealing plate of one wall panel component is fitted to the stepped groove formed by the other wall panel component, thereby causing the gap between the bent plates and the gap between the outer sealing plates to be staggered along the splicing direction, improving the sealing performance of the partition wall assembly. When the partition wall assembly is used in a liquid-cooled energy storage tank, it makes it difficult for moisture in the liquid-cooled cavity to enter the closed cavity through the partition wall assembly, improving the waterproof performance of the liquid-cooled energy storage tank. In addition, the mechanical fitting method improves the sealing performance of the partition wall assembly, making it less prone to aging and failure, with a long service life and easy maintenance.

[0014] For the positions between adjacent wall panel components, the first connecting part and the second connecting part are spliced ​​together to form a first joint, and two adjacent outer sealing panels are spliced ​​together to form a second joint; along the splicing direction, there is no overlap between the first joint and the second joint, and the first joint overlaps with the outer sealing panel.

[0015] Optionally, the dimension of the first seam along the splicing direction is the same as the dimension of the second seam along the splicing direction.

[0016] Optionally, the dimensions of the first seam and the second seam along the splicing direction are no greater than 3 mm.

[0017] Optionally, the first side of the outer sealing plate protrudes from the bent plate by 4mm to 8mm along the splicing direction.

[0018] Optionally, an insulation chamber for accommodating insulation material is formed between the outer sealing plate and the bent plate.

[0019] Alternatively, adjacent wall panel components may be connected by welding.

[0020] Optionally, adjacent wall panel components are connected by fasteners and / or adhesives.

[0022] A first floor, wherein the first floor is disposed in the liquid cooling cavity;

[0023] A second floor, disposed in the enclosed cavity, connected to the first floor, with the top surface of the second floor higher than the first floor; and

[0024] According to the above-described partition wall assembly, the partition wall assembly includes at least two wall panel members, the bottom end of the wall panel members being connected to the top surface of the first floor, and the side wall of the wall panel members adjacent to the enclosed cavity being connected to the side wall of the second floor.

[0053] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0054] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0055] Figures 1 to 5 A partition wall assembly 120 according to the present invention is shown for a liquid-cooled energy storage box 100, the liquid-cooled energy storage box 100 including a liquid-cooled cavity 101 and a closed cavity 102.

[0056] The partition wall assembly 120 includes at least two wall panel members 121, each wall panel member 121 including a bent plate 130 and an outer sealing plate 140. The two sides of the bent plate 130 are bent along the thickness direction D4 of the wall panel member 121 toward the side closer to the liquid cooling cavity 101 to form a first bent edge 131 and a second bent edge 132.

[0057] The outer sealing plate 140 is arranged along the thickness direction D4 on the side of the bent plate 130 near the liquid cooling cavity 101. Along the splicing direction D5 of the wall panel member 121 perpendicular to the thickness direction D4, the first side 141 of the outer sealing plate 140 protrudes from the first bent edge 131, and the second side 142 of the outer sealing plate 140 overlaps with the second bent edge 132 and forms a stepped groove 150 with the second bent edge 132.

[0058] In this arrangement, at least two wall panel components 121 are arranged along the splicing direction D5, and the first side 141 of the outer sealing plate 140 of at least one wall panel component 121 is fitted to the stepped groove 150 formed by the adjacent wall panel component 121.

[0059] According to the partition wall assembly 120 of this utility model, the partition wall assembly 120 includes at least two wall panel members 121, which are arranged along the splicing direction D5. In adjacent wall panel members 121, the first side 141 of the outer sealing plate 140 of one wall panel member 121 is fitted to the stepped groove 150 formed by the other wall panel member 121, thereby causing the gap between the bent plates 130 and the gap between the outer sealing plates 140 to be misaligned along the splicing direction D5, which improves the sealing performance of the partition wall assembly 120. When the partition wall assembly 120 is used in the liquid-cooled energy storage tank 100, it makes it difficult for moisture in the liquid-cooled cavity 101 to enter the closed cavity 102 through the partition wall assembly 120, thus improving the waterproof performance of the liquid-cooled energy storage tank 100. In addition, the mechanical fitting method improves the sealing performance of the partition wall assembly 120, making it less prone to aging and failure, with a long service life and easy maintenance.

[0060] Figure 1 A liquid-cooled energy storage box 100 according to the present invention is shown. The liquid-cooled energy storage box 100 includes a base frame 105, a top frame 106, corner posts 107, a box door 108, box wall panels 109, and a partition wall assembly 120 as described above. Along the height direction D3 of the liquid-cooled energy storage box 100, the base frame 105 is arranged below the top frame 106. The corner posts 107 extend along the height direction, with their top ends connected to the corners of the top frame 106 and their bottom ends connected to the corners of the base frame 105. The corner posts 107 are arranged at the four corners of the top frame 106 or the base frame 105 (the two ends of the length direction D1 of the liquid-cooled energy storage box 100 and the two sides of the width direction D2 of the liquid-cooled energy storage box 100), thereby constructing the main frame structure of the liquid-cooled energy storage box 100. Figure 2 As shown, the box door 108 and the box wall panel 109 are arranged on the side of the main frame, thereby forming a liquid cooling chamber, a battery chamber 103 and an electrical chamber 104 together with the partition wall assembly 120 arranged in the main frame mechanism. The battery chamber 103 and the electrical chamber 104 serve as the closed chamber 102 of the liquid cooling energy storage box 100 and need to be sealed and isolated from the liquid cooling chamber 101 and the outside of the liquid cooling energy storage box 100.

[0061] Reference Figure 2 The two partition wall components 120 are arranged perpendicularly to each other, thereby forming a liquid cooling cavity 101 with the corner structure of the main frame of the liquid cooling energy storage box 100. In other words, the liquid cooling cavity 101 is separated from the electrical cavity 104 and the battery cavity 103 by the two partition wall components 120 respectively.

[0062] The following is combined Figures 3 to 5 The specific structure of the partition wall component 120 is described.

[0063] In some embodiments of this utility model, reference is made to Figure 4Taking the partition wall assembly 120 between the battery cavity 103 and the liquid cooling cavity 101 as an example, for the position between adjacent wall panel components 121, along the splicing direction D5, the splice between the first bending edge 131 and the second bending edge 132 is staggered from the splice between the outer sealing plates 140, so that the water on the side of the liquid cooling cavity 101 cannot directly enter the battery cavity 103 through the gap between the outer sealing plates 140.

[0064] In some embodiments of this utility model, reference is made to Figure 4 The first bent edge 131 includes a first connecting part 134 and a first bent part 136. The first connecting part 134 is parallel to the thickness direction D4, and the first bent part 136 is connected to the first connecting part 134 and is parallel to the splicing direction D5, so that the cross section of the first bent edge 131 perpendicular to the height direction is L-shaped.

[0065] The second bent edge 132 includes a second connecting portion 135 and a second bent portion 137. The second connecting portion 135 is parallel to the thickness direction D4, and the second bent portion 137 is connected to the second connecting portion 135 and is parallel to the splicing direction D5, so that the cross section of the second bent edge 132 perpendicular to the height direction is L-shaped.

[0066] The arrangement of the first bending edge 131 and the second bending edge 132 not only gives the bending plate 130 a certain thickness, but also gives the bending plate 130 and the outer sealing plate 140 a sufficient contact area, which helps to ensure the structural strength of the wall panel component 121.

[0067] For adjacent wall panel components 121, the first connecting portion 134 and the second connecting portion 135 are spliced ​​together to form a first joint 138, and two adjacent outer sealing plates 140 are spliced ​​together to form a second joint 143. Along the splicing direction D5, there is no overlap between the first joint and the second joint, and the first joint overlaps with the outer sealing plate 140. This allows the gap between the first bent edge 131 and the second bent edge 132 (i.e., the first joint) to be blocked by the outer sealing plate 140, thereby preventing moisture from the liquid cooling cavity 101 from entering through the outer sealing plate 140 and improving the sealing performance of the partition wall assembly 120.

[0068] In some embodiments of this utility model, reference is made to Figure 5 The bending plate 130 is also provided with a third bending edge 133. The third bending edge 133 is L-shaped and is arranged at the top and bottom of the bending plate 130 along the height direction D3 of the liquid-cooled energy storage box 100, thereby further increasing the connection contact area between the bending plate 130 and the outer sealing plate 140, which is conducive to ensuring the structural strength of the wall panel component 121.

[0069] The outer sealing plate 140 is connected to the portion of the bent plate 130 perpendicular to the thickness direction D4, such as the first bend 136 of the first bend 131, the second bend 137 of the second bend 132, and the outer wall of the third bend 133, so that there is a fitting portion between the outer sealing plate 140 and the bent plate 130, thereby providing sufficient support for the outer sealing plate 140, making the outer sealing plate 140 less prone to deformation, and thus making the connection between the outer sealing plate 140 and the bent plate 130 less prone to deformation and damage, thereby improving the sealing performance of the wall panel component 121.

[0070] In some embodiments of this utility model, reference is made to Figures 3 to 5 An insulation chamber 160 is formed between the bent plate 130 and the outer sealing plate 140 of the wall panel component 121 to accommodate the insulation material, thereby giving the wall panel component 121 insulation performance and improving the thermal insulation performance of the liquid-cooled energy storage box 100. Insulation chambers 160 can also be formed within the box wall panel 109 and the box door 108 of the liquid-cooled energy storage box 100, further ensuring the thermal insulation performance of the liquid-cooled energy storage box 100.

[0071] In some embodiments of this utility model, reference is made to Figure 4 The dimensions of the first joint 138 along the splicing direction D5 are the same as those of the second joint 143 along the splicing direction D5, thereby making the splicing between the wall panel components 121 more stable and preventing one of the first joint 138 and the second joint 143 from being too large and affecting the sealing between the wall panel components 121.

[0072] In some embodiments of this utility model, reference is made to Figure 4 The dimensions h1 of the first joint 138 along the splicing direction D5 and h2 of the second joint 143 along the splicing direction D5 are both no greater than 3mm. This prevents excessively large dimensions of the first joint 138 and the second joint 143 from allowing moisture to easily pass between the wall panel components 121, further ensuring the airtightness between the wall panel components 121. Generally, the dimensions h1 of the first joint 138 along the splicing direction D5 and h2 of the second joint 143 along the splicing direction D5 can be 2mm. This ensures the airtightness between the wall panel components 121 and also facilitates welding (or glued connection) between the bent plates 130 and between the outer sealing plates 140.

[0073] In some embodiments of this utility model, reference is made to Figure 4The first side 141 of the outer sealing plate 140 protrudes from the bending plate 130 by a dimension h3 of 4mm to 8mm along the splicing direction D5, so that the outer sealing plate 140 can extend to the stepped groove 150 and cover the first joint 138, making it difficult for moisture from the liquid cooling cavity 101 to enter the first joint 138, thereby ensuring the airtightness of the partition wall assembly 120.

[0074] The liquid-cooled energy storage box 100 according to this utility model further includes a first floor 110 and a second floor 111. The first floor 110 is disposed in the liquid-cooled cavity 101 and connected to the base frame 105. The second floor 111 is disposed in the enclosed cavity 102 (to... Figure 5 For example, the enclosed cavity 102 is the battery cavity 103 and is connected to the base frame 105. The second floor 111 is connected to the first floor 110, and the top surface of the second floor 111 is higher than the first floor 110.

[0075] The bottom end of the wall panel member 121 of the partition wall assembly 120 is connected to the top surface of the first floor 110, and the proximal end of the wall panel member 121 is connected to the enclosed cavity 102 (i.e., Figure 5 The sidewall of the battery cavity 103 is connected to the sidewall of the second floor 111.

[0076] According to the liquid-cooled energy storage box 100 of this utility model, a high-low step structure is formed between the first floor 110 and the second floor 111, and the partition wall assembly 120 is connected to the high-low step structure, thereby making the bottom of the partition wall assembly 120 more waterproof, and the sealing structure of the liquid-cooled energy storage box 100 is not prone to aging and failure, has a long service life, and is easy to maintain.

[0077] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The adjacent wall panel components 121 are connected by welding, resulting in a stable structure. Preferably, the outer sealing plates 140 and the bent plates 130 of adjacent wall panel components 121 are fully welded together for better sealing. The wall panel components 121 and the first floor 110 can also be connected by welding, and the full welding connection between the wall panel components 121 and the first floor 110 can further improve the sealing performance of the liquid-cooled energy storage tank 100.

[0078] In some other embodiments of this utility model, adjacent wall panel components 121 are connected by fasteners, such as riveting and bolting between wall panel components 121, or adhesive can be used for connection. Due to the structural design of the partition wall assembly 120, the basic waterproof performance requirements of the liquid-cooled energy storage box 100 can also be met.
