Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling boxes, in particular to a sealed liquid cooling box. Background Art

[0002] With the development of the new energy industry, the demand for battery system energy density is increasing. Developing large-capacity single cells has become one of the most effective means. However, this also brings with it the safety issue of battery thermal runaway. As large-capacity single cells become larger, the heat inside the core cannot be quickly transferred away. This causes heat accumulation in the assembled battery pack, which can easily cause fire and explosion. To address this problem, existing battery boxes are often equipped with liquid cooling systems.

[0003] In the prior art, such as Chinese Patent CN111106268A, a liquid-cooled battery case comprises a case bottom plate and a liquid cooling plate. The liquid cooling plate is provided with a coolant flow channel and a flow channel opening. The liquid cooling plate includes a main body located within the case bottom plate or directly forming the case bottom plate. The main body of the liquid cooling plate is provided with an upwardly folded annular flange around its periphery. The flange contains a curved flow channel that communicates with the coolant flow channel. The flow channel opening is located on the side of the flange and is connected to the coolant flow channel through the curved flow channel. The liquid-cooled battery case also includes an annular outer frame surrounding the flange and clamped to the outside of the flange. Placing the flow channel opening on the flange increases its height and prevents interference with other structures at the bottom of the case. Furthermore, the outer frame clamped around the outer periphery of the flange protects the liquid cooling plate, preventing deformation of the main body of the liquid cooling plate from compression by the battery modules or damage from impact with external structures.

[0004] In the above patent, although an outer frame is provided on the outside of the folded edge to support and protect the liquid cooling plate shape, thereby preventing the main board of the liquid cooling plate from being deformed due to the squeezing of the battery module and improving the overall support strength, due to the sealing requirement, the main board and the outer frame are tightly fixedly connected, and a flow cavity for the liquid cooling medium is formed between the two. After long-term use, impurities are easily accumulated and adhered in the flow cavity of the liquid cooling medium, causing the liquid cooling flow channel to be blocked, which makes it difficult to disassemble and clean it, resulting in inconvenience in later cleaning and maintenance. Therefore, it is necessary to propose a new type of sealed liquid cooling box. Utility Model Content

[0005] The utility model mainly provides a sealed liquid cooling box body which is convenient for quick disassembly and assembly of an outer shell and a liquid cooling plate, and avoids difficulty in cleaning after the two are fixedly connected.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a sealed liquid cooling box, including an outer shell and a liquid cooling plate, the rear surface of the outer shell is symmetrically fixedly connected to the second fixed block, the opposite surfaces of the two second fixed blocks are fixedly connected to the fixing rod, the outer surface of the fixing rod is rotatably connected to the rotating block, the front surface of the rotating block is fixedly connected to the rear surface of the liquid cooling plate, the front surface of the outer shell is fixedly connected to the first fixed block near the top, the inner surface of the first fixed block is threadedly rotatably connected to the threaded rod, the front surface of the liquid cooling plate is fixedly connected to the fixing plate, and a through hole is opened on the top of the fixing plate.

[0007] Preferably, the bottom of the threaded rod is fixedly connected to a butterfly block, and the outer surface of the threaded rod is rotatably connected to the inner surface of the through hole by thread, so that the threaded rod can be driven to rotate and be threadedly connected to the through hole by manually rotating the butterfly block.

[0009] Preferably, a flow groove is opened at the bottom of the liquid cooling plate, and the outer surface of the liquid cooling plate is in contact with the inner surface of the outer shell. The close contact between the liquid cooling plate and the outer shell facilitates the flow of the delayed flow groove to absorb the heat on the surface of the liquid cooling plate when the liquid cooling medium flows.

[0010] Preferably, a mounting groove is provided on the top of the outer shell, and the outer surface of the liquid cooling plate fits with the inner surface of the mounting groove, so that the edge protrusion of the liquid cooling plate is conveniently limited in the mounting groove.

[0011] Preferably, a sealing gasket is provided between the liquid cooling plate and the mounting groove, and the sealing gasket and the liquid cooling plate are matched with each other, so that when the liquid cooling plate and the outer shell are tightly fitted, the sealing gasket between the mounting grooves is squeezed to deform and fill the connection gap between the two to seal.

[0012] Preferably, the front surface of the outer shell is fixedly connected to the liquid inlet pipe, and the front surface of the outer shell is fixedly connected to the liquid outlet pipe at a position away from the liquid inlet pipe, so that the liquid cooling medium can enter the flow groove through the liquid inlet pipe and enter the liquid outlet pipe from the outlet of the flow groove for discharge.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, when in use, through the coordinated arrangement of the outer shell, the liquid cooling plate, the first fixed block, the butterfly block, the threaded rod, the second fixed block, the fixed rod, the rotating block, the flow groove, the sealing gasket, the fixed plate and the hollow block, the liquid cooling plate can be rotated open on the outer surface of the fixed rod by the rotating block, exposing its liquid cooling medium flow cavity and cleaning it, and when the threaded rod is threadedly connected to the through hole and the hollow block, the liquid cooling plate and the outer shell can be tightly fitted and sealed, and the liquid cooling box can be quickly disassembled and cleaned, which solves the problem in the background technology that after long-term use, impurities are easily accumulated and adhered in the flow cavity of the liquid cooling medium, causing the liquid cooling flow channel to be blocked, making it difficult to disassemble and clean it, resulting in inconvenience in later cleaning and maintenance.

[0015] 2. In the utility model, when in use, by fixing the butterfly block at the bottom of the threaded rod, it is convenient for personnel to manually rotate the threaded rod without the aid of tools, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] See also Figure 1-5 The utility model provides a technical solution: a sealed liquid cooling box, including an outer shell 1 and a liquid cooling plate 2, the rear surface of the outer shell 1 is symmetrically fixedly connected to the second fixed block 6, the opposite surfaces of the two second fixed blocks 6 are fixedly connected to the fixing rod 7, the outer surface of the fixing rod 7 is rotatably connected to the rotating block 8, the front surface of the rotating block 8 is fixedly connected to the rear surface of the liquid cooling plate 2, the front surface of the outer shell 1 is fixedly connected to the first fixed block 3 near the top, the inner surface of the first fixed block 3 is threaded and rotatably connected to the threaded rod 5, the front surface of the liquid cooling plate 2 is fixedly connected to the fixing plate 11, and a through hole 15 is provided on the top of the fixing plate 11.

[0025] like Figure 1 -and Figure 3-4 As shown, the bottom of the threaded rod 5 is fixedly connected to the butterfly block 4, and the outer surface of the threaded rod 5 is threadedly connected to the inner surface of the through hole 15, so that the threaded rod 5 can be rotated and threadedly connected to the through hole 15 by manually rotating the butterfly block 4.

[0026] like Figure 1-4 As shown, the top of the fixed plate 11 is fixedly connected to the hollow block 12, and the hollow block 12 is connected to the through hole 15. The inner surface of the hollow block 12 is threadedly connected to the outer surface of the threaded rod 5, so that when the threaded rod 5 is threadedly connected to the fixed plate 11, the threaded contact surface of the threaded rod 5 can be increased by setting the hollow block 12.

[0027] like Figure 5 As shown, a flow groove 9 is opened at the bottom of the liquid cooling plate 2, and the outer surface of the liquid cooling plate 2 is in contact with the inner surface of the outer shell 1. The close contact between the liquid cooling plate 2 and the outer shell 1 facilitates the flow of the delayed flow groove 9 to absorb the heat on the surface of the liquid cooling plate 2 when the liquid cooling medium flows.

[0028] like Figure 4 As shown, a mounting groove 16 is provided on the top of the outer shell 1 , and the outer surface of the liquid cooling plate 2 fits with the inner surface of the mounting groove 16 , so that the edge protrusion of the liquid cooling plate 2 is conveniently limited in the mounting groove 16 .

[0029] like Figure 4 As shown, a sealing gasket 10 is provided between the liquid cooling plate 2 and the mounting groove 16. The sealing gasket 10 and the liquid cooling plate 2 are matched with each other so that when the liquid cooling plate 2 and the outer shell 1 are tightly fitted, the sealing gasket 10 between the mounting grooves 16 is squeezed to deform and fill the connection gap between the two for sealing.

[0030] like Figure 1-2 and Figure 4 As shown, the front surface of the outer shell 1 is fixedly connected to the liquid inlet pipe 13, and the front surface of the outer shell 1 is fixedly connected to the liquid outlet pipe 14 at a position away from the liquid inlet pipe 13, so that the liquid cooling medium can enter the flow groove 9 through the liquid inlet pipe 13 and enter the liquid outlet pipe 14 from the outlet of the flow groove 9 for discharge.

[0031] The method of use and working principle of this device: When the sealed liquid cooling box is used, the second fixing blocks 6 are symmetrically fixedly connected to the rear surface of the outer shell 1, and a fixing rod 7 is fixedly connected between the two second fixing blocks 6. The liquid cooling plate 2 is rotatably connected to the outer surface of the fixing rod 7 through the rotating block 8. When the butterfly block 4 is held and rotated counterclockwise to drive the threaded rod 5 to rotate the internal thread of the first fixing block 3, the threaded rod 5 will gradually be screwed out from the through hole 15 and the internal thread of the hollow block 12 until it is separated from the fixing plate 11. The personnel can flip the liquid cooling plate 2 upward to make it rotate. The fixing rod 7 is pivoted and opened, thereby exposing the bottom of the liquid cooling plate 2 and the interior of the outer shell 1, making it easier for personnel to clean the flow groove 9 and the impurities and sludge accumulated inside the outer shell 1. The installation 16 is opened at the top of the outer shell 1, making it easier to place the sealing gasket 10 on its top. After the liquid cooling plate 2 is cleaned and the threaded rod 5 is threadedly connected to the through hole 15 and the hollow block 12, the raised edge of the liquid cooling plate 2 will tightly squeeze the sealing gasket 10, causing it to deform and fill the space between the outer shell 2 and the liquid cooling plate 2, thus achieving a good sealing effect. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention in any other form. Anyone skilled in the art may use the above-disclosed technical content to modify or modify it into an equivalent embodiment with equivalent variations and applications in other fields. However, any simple modification, equivalent variation, and modification of the above embodiment based on the technical essence of the present invention that does not depart from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
