Description
Technical Field
[0001] This utility model relates to the field of solid-state battery technology, specifically to a liquid cooling component for solid-state batteries. Background Technology
[0002] Liquid cooling components for solid-state batteries mainly include liquid cooling plates, coolant, pumps, and piping networks. These components together form a highly efficient liquid cooling system that uses circulating coolant to transfer and remove excess heat generated by the battery during charging and discharging, thereby ensuring the safe and stable operation of the battery.
[0003] Conventional liquid cooling components have a relatively small contact area between their pipe network and solid-state batteries, resulting in limited heat dissipation. At the same time, the pipe network itself lacks a certain degree of structural protection, making it susceptible to unnecessary damage from external factors, thereby affecting the cooling effect on the battery.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a liquid cooling component for solid-state batteries. Utility Model Content
[0005] The purpose of this invention is to provide a liquid cooling component for solid-state batteries to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid cooling assembly for solid-state batteries, comprising a liquid cooling structure and a heat-conducting structure. The top of the liquid cooling structure is equipped with a heat-conducting structure, and a stabilizing frame is installed on the top of the heat-conducting structure. The bottom of the liquid cooling structure is equipped with a base structure, and heat dissipation fins are provided on the bottom of the base structure. Protective structures are provided on both the left and right sides of the base structure. The heat-conducting structure includes an upper heat-conducting plate, an upper direct cooling plate, mounting holes, and anti-slip textures. The upper direct cooling plate is attached to the surface of the upper heat-conducting plate near the liquid cooling structure. Mounting holes are provided at one end of the upper direct cooling plate and the upper heat-conducting plate. Anti-slip textures are provided on the surface of the upper heat-conducting plate away from the upper direct cooling plate.
[0007] Furthermore, the liquid cooling structure includes an input quick connector, a manifold, a refrigerant pipe, a return pipe, and an output quick connector. One end of the input quick connector is connected to the manifold, and the end of the manifold away from the input quick connector is connected to the refrigerant pipe. The end of the refrigerant pipe away from the manifold is connected to the return pipe, and the middle of the return pipe is connected to the output quick connector.
[0008] Furthermore, the output quick connector and the input quick connector adopt the same structure. The shunt pipe, refrigerant pipe and return pipe are welded to each other. The shunt pipe is connected to the input quick connector through a quick connector structure, and the output quick connector is connected to the shunt pipe through a quick connector structure.
[0009] Furthermore, the upper direct cooling plate and the upper heat-conducting plate are fixedly connected, and the upper direct cooling plate has a groove structure on the side surface near the liquid cooling structure that is the same as the side surface structure of the liquid cooling structure.
[0010] Furthermore, the base structure includes a lower heat-conducting plate, a lower direct-cooling plate, a protective frame, and thermal grease. The lower direct-cooling plate is installed on the side of the lower heat-conducting plate closest to the liquid cooling structure, and protective frames are provided on both the left and right sides of the lower heat-conducting plate. The side of the lower direct-cooling plate closest to the heat dissipation fins is coated with thermal grease.
[0011] Furthermore, the lower heat-conducting plate has a groove structure on the side surface near the heat dissipation fins that matches the top surface structure of the heat dissipation fins, and the lower direct cooling plate has a groove structure on the side surface near the liquid cooling structure that is the same as the side surface structure of the liquid cooling structure.
[0012] Furthermore, the protective structure includes a protective grille, a heat dissipation plate, and a thermal insulation pad. The heat dissipation plate is connected to one side of the protective grille, and the surface of the heat dissipation plate away from the protective grille is covered with a thermal insulation pad.
[0013] Furthermore, the protective structure is simultaneously fixedly installed on the left and right sides of the heat-conducting structure and the base structure, and the heat insulation pad is attached to the side surface of the heat-conducting structure and the base structure.
[0014] This invention provides a liquid cooling component for solid-state batteries, which has the following advantages:
[0015] 1. This utility model, by setting a heat-conducting structure and a stabilizing frame on the top of the liquid-cooled structure, allows for the rapid conduction of heat generated during battery operation through the cooperation of the upper heat-conducting plate and the upper direct cooling plate. The circulating coolant inside the liquid-cooled structure transfers and removes the conducted heat. Meanwhile, the anti-slip texture on one side of the upper heat-conducting plate ensures that the battery can adhere to the surface of the upper heat-conducting plate while preventing unnecessary slippage. The structure of the stabilizing frame provides a certain degree of structural restraint for the series-connected solid-state batteries, helping to ensure the structural stability of the batteries. At the same time, the stabilizing frame itself can also provide shock absorption protection for the batteries, reducing the impact of external forces on the batteries.
[0016] 2. This utility model, by setting a base structure and heat dissipation fins at the bottom of the liquid cooling structure, utilizes the structure of the lower heat-conducting plate and the lower direct cooling plate to absorb and conduct heat that has not been removed from the liquid cooling structure in time. Combined with thermal grease and heat dissipation fins, it can provide maximum heat dissipation assistance, thereby ensuring the effectiveness of the liquid cooling structure. Simultaneously, because the upper and lower direct cooling plates have grooves on one side surface that are identical to the side surface of the liquid cooling structure, the heat-conducting structure and the base structure can enclose the entire liquid cooling structure, maximizing the contact surface area between the structures to ensure heat conduction and heat dissipation, while also providing good structural protection for the liquid cooling structure. Furthermore, the protective structures on the left and right sides, using heat dissipation plates and thermal insulation pads, prevent external heat from being transferred to the heat-conducting structure and the base structure, while also providing heat dissipation assistance. The protective grille serves to protect the side structure of the entire device, ensuring its service life. Attached Figure Description

The heat-conducting structure 2 includes an upper heat-conducting plate 201, an upper direct cooling plate 202, mounting holes 203, and anti-slip textures 204. An upper direct cooling plate 202 is attached to the surface of the liquid cooling structure 1, and an assembly hole 203 is provided at one end of the upper direct cooling plate 202 and the upper heat-conducting plate 201. Anti-slip texture 204 is provided on the surface of the upper heat-conducting plate 201 away from the upper direct cooling plate 202. The upper direct cooling plate 202 and the upper heat-conducting plate 201 are fixedly connected. A groove structure identical to the side surface of the liquid cooling structure 1 is provided on the surface of the upper direct cooling plate 202 closest to the liquid cooling structure 1. The liquid cooling structure 1 includes an input quick connector 10. 1. A manifold 102, a refrigerant pipe 103, a return pipe 104, and an output quick connector 105. One end of the input quick connector 101 is connected to the manifold 102, and the end of the manifold 102 furthest from the input quick connector 101 is connected to the refrigerant pipe 103. The end of the refrigerant pipe 103 furthest from the manifold 102 is connected to the return pipe 104, and the middle of the return pipe 104 is connected to the output quick connector 105. The output quick connector 105 has the same structure as the input quick connector 101. The manifold 102... 2. The refrigerant pipe 103 and the return pipe 104 are welded together, and the branch pipe 102 is connected to the input quick connector 101 through a quick connector structure. The output quick connector 105 is connected to the branch pipe 102 through a quick connector structure. With the cooperation of the upper heat conduction plate 201 and the upper direct cooling plate 202, the heat generated during battery power operation can be conducted quickly to the maximum extent. The coolant circulating inside the liquid cooling structure 1 is used to transfer and remove the conducted heat.
[0025] like Figures 1 to 5As shown, the base structure 4 includes a lower heat-conducting plate 401, a lower direct-cooling plate 402, a protective frame 403, and thermal grease 404. The lower direct-cooling plate 402 is mounted on the side of the lower heat-conducting plate 401 closest to the liquid-cooling structure 1, and protective frames 403 are provided on both the left and right sides of the lower heat-conducting plate 401. The side of the lower direct-cooling plate 402 closest to the heat dissipation fins 5 is coated with thermal grease 404. The side of the lower heat-conducting plate 401 closest to the heat dissipation fins 5 has a groove structure that matches the top surface structure of the heat dissipation fins 5, and the side of the lower direct-cooling plate 402 closest to the liquid-cooling structure 1 has a groove structure that is the same as the side surface structure of the liquid-cooling structure 1. The protective structure 6 includes a protective grille 601, a heat sink, and a heat sink. The heat plate 602 and the heat insulation pad 603 are connected to one side of the protective grille 601.

With the help of the heat dissipation grease 404 and the heat dissipation fins 5, the heat dissipation assistance can be maximized to ensure the heat dissipation effectiveness of the liquid cooling structure 1.
[0026] In summary, as Figures 1 to 5 As shown, the liquid cooling component for solid-state batteries is used by first arranging the solid-state batteries that need to be connected in series inside the stable frame 3 using the structure of the stable frame 3, so as to ensure the overall structural stability of the battery. Then, the liquid cooling structure 1 is connected to the external coolant circulation supply equipment through the input quick connector 101 and the output quick connector 105 to ensure the subsequent coolant delivery.
[0027] When the coolant is delivered, it enters the interior of the entire liquid cooling structure 1 from the input quick connector 101, and flows through the branch pipe 102, refrigerant pipe 103 and return pipe 104 in sequence, and finally flows back into the coolant circulation supply equipment from the output quick connector 105, thus forming a reciprocating liquid cooling path.
[0028] During this process, the heat generated by the battery operation will be quickly conducted into the interior of the liquid cooling structure 1 by the upper heat conduction plate 201 and the upper direct cooling plate 202. The heat will be transferred and removed by the coolant circulating inside the liquid cooling structure 1. The heat that is not transferred and removed in time will be quickly transferred by the lower heat conduction plate 401 and the lower direct cooling plate 402. Some of the heat will be quickly dissipated by the heat dissipation fins 5 attached to it using the thermal grease 404. The rest will be absorbed and dissipated to the outside by the heat dissipation plate 602 on one side of the protective grille 601. The thermal insulation pad 603 reduces the amount of external heat entering the interior of the heat conduction structure 2 and the base structure 4.
