Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plate trays, and specifically relates to an installation structure of a liquid cooling plate tray. Background Technique

[0002] Compared with traditional fuel vehicles, electric vehicles have the advantages of energy conservation, environmental protection, low use and maintenance costs, and high intelligence. Therefore, they are increasingly favored by consumers. The thermal management of the battery system in electric vehicles is particularly important. For this reason, the industry has adopted the method of liquid cooling plate heat dissipation, and the battery module is dissipated through the liquid cooling plate tray.

[0003] In the patent application with the authorization publication number of CN221304793U, the authorization publication date of July 9, 2024, and the name of "An Installation Structure of a Battery Liquid Cooling Plate", it includes a frame and a pressing strip. A boss is arranged below the inner wall of the frame. The liquid cooling plate is fastened to the boss through the pressing strip. The module end plate is carried on the pressing strip, and the module is carried on the module end plate. A pressing strip with a mountain-shaped structure is installed around the liquid cooling plate, and the liquid cooling plate is fixed on the boss of the frame through the pressing strip. It does not require damaging the liquid cooling plate or drilling holes in the liquid cooling plate for fixation. At the same time, it also reduces the usage amount of bolts and lowers the installation difficulty. The module end plate is carried on the pressing strip, so that the weight of the module end plate and the module is transmitted to the pressing strip and then to the boss of the frame. The liquid cooling plate is not used as a load-bearing component, reducing the damage to the liquid cooling plate. A sponge layer is arranged between the liquid cooling plate and the bottom guard plate to prevent the vibration of the vehicle body from being transmitted to the liquid cooling plate through the bottom guard plate, thereby damaging the liquid cooling plate.

[0004] Although the existing liquid cooling plate installation structure does not use the liquid cooling plate as a load-bearing component and reduces the damage to the liquid cooling plate, it is found in use that since the liquid cooling plate is mainly used to dissipate heat from the battery module, and in the existing liquid cooling plate installation structure, there is a pressing strip between the battery module and the liquid cooling plate, resulting in a gap between the battery module and the liquid cooling plate, making it inconvenient for the battery module to transfer heat to the liquid cooling plate, resulting in poor heat dissipation effect of the battery module and inconvenient use. Therefore, we propose an installation structure of a liquid cooling plate tray to solve the problems raised above. Content of the Utility Model

[0029] Please refer to Figures 1 to 4 , an installation structure of a liquid cooling plate tray, including a frame 1. A boss 2 is fixedly connected to the inner side of the frame 1 near the lower part. A protective bottom plate 3 is arranged at the bottom of the boss 2. Among them,

[0030] A liquid cooling plate 4 is arranged above the boss 2. A sealing gasket 5 is installed at the top of the liquid cooling plate 4 near the side. A battery module 6 is arranged above the sealing gasket 5. The battery module 6 and the liquid cooling plate 4 are detachably connected through a connecting mechanism 7. A coolant groove 10 is opened inside the liquid cooling plate 4;

[0031] A heat-conducting glue injection hole 11 is opened in the middle of one end of the liquid cooling plate 4. Exhaust holes 12 are symmetrically opened at the end of the liquid cooling plate 4 far from the heat-conducting glue injection hole 11.

[0032] When the liquid cooling plate 4 needs to be installed, the gasket 5 is installed on the top of the liquid cooling plate 4. Then, the battery module 6 is fixedly connected to the liquid cooling plate 4 through the connecting mechanism 7. The heat-conducting glue is injected into the gap between the battery module 6 and the liquid cooling plate 4 through the heat-conducting glue injection hole 11, and the air in the gap is discharged through the exhaust hole 12. After the heat-conducting glue solidifies, the protective bottom plate 3 and the liquid cooling plate 4 are installed on the boss 2 through the disassembly and assembly mechanism. Through this installation structure, the weight of the battery module 6 is transmitted to the edge of the liquid cooling plate 4 through the gasket 5, and then transmitted to the boss 2, avoiding using the liquid cooling plate 4 as a load-bearing component of the battery module 6 and preventing the liquid cooling plate 4 from being damaged. At the same time, the heat-conducting glue conducts heat between the battery module 6 and the liquid cooling plate 4, enabling the battery module 6 and the liquid cooling plate 4 to be in close contact, thereby facilitating the battery module 6 to transfer heat to the liquid cooling plate 4 and facilitating heat dissipation of the battery module 6.

Both the gasket 5 and the clamping block 9 are made of rubber material, and the gasket 5 and the clamping block 9 are integrally fixedly connected. When placing the gasket 5, the gasket 5 drives the clamping block 9 to insert into the clamping groove 8. Through the clamping connection formed by the clamping block 9 and the clamping groove 8, the gasket 5 is installed on the top of the liquid cooling plate 4, preventing relative movement between the gasket 5 and the liquid cooling plate 4 and avoiding misalignment of the gasket 5.

[0034] Please refer to Figures 1 to 4 , the connecting mechanism 7 includes a first connecting frame 701, a second connecting frame 702 and a bolt 703.

The first connecting frame 701 and the second connecting frame 702 are fixedly connected through the bolt 703. After the gasket 5 is installed on the liquid cooling plate 4, the battery module 6 is placed on the gasket 5. After the first connecting frame 701 and the second connecting frame 702 are aligned, the first connecting frame 701 and the second connecting frame 702 are fixedly connected through the bolt 703, thereby fixedly connecting the battery module 6 and the liquid cooling plate 4.

The disassembly and assembly mechanism includes a first screw hole 13. The bosses 2 are symmetrically penetrated with first screw holes 13 corresponding to the four corners of the liquid cooling plate 4. The protective bottom plate 3 is penetrated with second screw holes 14 corresponding to the positions of the first screw holes 13. A screw 15 is fixedly connected to the bottom of the liquid cooling plate 4 corresponding to the first screw holes 13 and the second screw holes 14. A nut 16 is arranged below the second screw hole 14 corresponding to the protective bottom plate 3. When it is necessary to install the liquid cooling plate 4 and the protective bottom plate 3 on the boss 2, the liquid cooling plate 4 is driven to insert the screw 15 into the first screw hole 13 of the boss 2, and then the protective bottom plate 3 is sleeved on the screw 15 through the second screw hole 14, and then the nut 16 is screwed on, so that the liquid cooling plate 4 and the protective bottom plate 3 can be fixed on the boss 2, so as to install the liquid cooling plate 4 and the protective bottom plate 3, and at the same time facilitate disassembly during later maintenance.

[0036] Working principle: When using the installation structure of the liquid cooling plate tray, as Figures 1 to 4 shown, first, when it is necessary to install the liquid cooling plate 4, the sealing gasket 5 is installed on the top of the liquid cooling plate 4, and then the battery module 6 is fixedly connected with the liquid cooling plate 4 through the connecting mechanism 7. Heat-conducting adhesive is injected into the gap between the battery module 6 and the liquid cooling plate 4 through the heat-conducting adhesive injection hole 11, and the air in the gap is discharged through the exhaust hole 12. After the heat-conducting adhesive solidifies, the protective bottom plate 3 and the liquid cooling plate 4 are installed on the boss 2 through the disassembly and assembly mechanism. Through this installation structure, the weight of the battery module 6 is transmitted to the edge of the liquid cooling plate 4 through the sealing gasket 5, and then transmitted to the boss 2, avoiding using the liquid cooling plate 4 as a load-bearing component of the battery module 6 and preventing the liquid cooling plate 4 from being damaged. At the same time, heat transfer is carried out between the battery module 6 and the liquid cooling plate 4 through the heat-conducting adhesive, so that the battery module 6 and the liquid cooling plate 4 can be in close contact, thereby facilitating the battery module 6 to transfer heat to the liquid cooling plate 4 and facilitating heat dissipation of the battery module 6. When placing the sealing gasket 5, the sealing gasket 5 drives the clamping block 9 to insert into the clamping groove 8, and through the clamping connection formed by the clamping block 9 and the clamping groove 8, the sealing gasket 5 is installed on the top of the liquid cooling plate 4, avoiding relative movement between the sealing gasket 5 and the liquid cooling plate 4 and preventing the sealing gasket 5 from being displaced. And when it is necessary to install the liquid cooling plate 4 and the protective bottom plate 3 on the boss 2, the liquid cooling plate 4 is driven to insert the screw 15 into the first screw hole 13 of the boss 2, and then the protective bottom plate 3 is sleeved on the screw 15 through the second screw hole 14, and then the nut 16 is screwed on, so that the liquid cooling plate 4 and the protective bottom plate 3 can be fixed on the boss 2, so as to install the liquid cooling plate 4 and the protective bottom plate 3, and at the same time facilitate disassembly during later maintenance.
