Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a liquid-cooled plate flow resistance testing device for power batteries of new energy vehicles. Background Technology

[0002] Against the backdrop of the rapid development of the new energy vehicle industry, in order to achieve efficient heat dissipation of power batteries, liquid cooling systems have become the mainstream solution due to their advantages of uniform heat dissipation and high efficiency. As a key component of the liquid cooling system, the flow resistance performance of the liquid cooling plate directly determines the flow efficiency of the coolant and the heat dissipation effect.

[0003] Current liquid cooling plate flow resistance testing devices on the market have significant shortcomings in their compatibility with liquid cooling plates of different sizes. Most devices have an integrated design for fixing the liquid cooling plate, which can only be matched with liquid cooling plates of specific sizes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a liquid-cooled plate flow resistance testing device for power batteries of new energy vehicles, which aims to improve the problem that the fixed structure of the traditional liquid-cooled plate flow resistance testing device is an integrated design that can only match liquid-cooled plates of specific sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flow resistance testing device for liquid-cooled plates used in power batteries for new energy vehicles includes a workbench. A fixed plate is fixedly connected inside the workbench, and a clamping mechanism is fixedly connected inside the fixed plate. The clamping mechanism includes a first electric push rod, the outer side of which is fixedly connected to the inside of the fixed plate. The output end of the first electric push rod is connected to a first clamping plate. A linkage component is rotatably connected inside the first clamping plate. A second electric push rod is fixedly connected to the top of one side of the workbench. The output end of the second electric push rod is connected to a support plate. A fixed block is fixedly connected to the top of the support plate. A first connecting pipe is fixedly connected to the outer side of the fixed block, and a second connecting pipe is disposed inside the fixed block.

[0007] The above technical solution involves placing the liquid cooling plate on a fixed plate, then activating the first electric push rod to pull the first clamping plate, which in turn drives the linkage components to clamp the liquid cooling plate. Simultaneously, the second electric push rod is activated to push the second connecting pipe at the top of the support plate to test the liquid cooling plate, thereby achieving the effect of adapting to liquid cooling plates of different sizes.

[0008] Preferably, the linkage component includes a connecting rod, one end of which is rotatably connected to the inside of a first clamping plate, the middle part of which is rotatably connected to the inside of a fixed plate, and the end of the connecting rod away from the first clamping plate is rotatably connected to a second clamping plate, the inside of which is slidably connected to the inside of the worktable.

[0009] Preferably, the clamping mechanism further includes a motor, which is externally fixedly connected to the outside of the fixed plate. The output end of the motor is connected to a first gear, and the tooth end of the first gear is meshed with a second gear. A threaded rod is internally fixedly connected to the second gear, and a third clamping plate is externally threadedly connected to the threaded rod. The two ends of the threaded rod are rotatably connected to the inside of the worktable, and the middle part of the threaded rod is rotatably connected to the inside of the fixed plate.

[0010] Preferably, the first clamping plate is slidably connected to the inside of the worktable, and the input end of the first connecting pipe is connected to the top of the worktable.

[0011] Preferably, a fixing tube is fixedly connected inside the fixing block, a spring is provided inside the fixing tube, and a second washer is provided at one end of the spring.

[0012] Preferably, the outer surface of the second gasket is disposed at one end of the second connecting tube, and the outer surface of the second gasket is slidably connected to the inside of the fixed tube.

[0013] Preferably, the top of the workbench is fixedly connected to a track, and the outside of the track is slidably connected to the inside of the support plate.

[0014] Preferably, a first gasket is provided inside the fixing block, and the outside of the first gasket is provided inside the second connecting pipe.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the first clamping plate is slid by the first electric push rod, thereby the first clamping plate drives the linkage component to slide. The two cooperate with each other to stably clamp the liquid cooling plate, thereby adapting to liquid cooling plates of different sizes and improving the convenience of processing.

[0017] 2. In this utility model, by pushing the second connecting tube, the sliders on both sides of the second connecting tube slide, and then rotating the second connecting tube, the spring releases its elastic force to push the second washer, causing the second connecting tube to pop out automatically. This allows for quick replacement of the matching connector, thereby improving the versatility and utilization of the testing device. Attached Figure Description

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1:

[0027] Reference Figure 1 and Figure 2This utility model provides an embodiment of a liquid-cooled plate flow resistance testing device for power batteries of new energy vehicles, including a workbench 1, a fixed plate 2 fixedly connected inside the workbench 1, a clamping mechanism 3 fixedly connected inside the fixed plate 2, the clamping mechanism 3 including a first electric push rod 301, the first electric push rod 301 being fixedly connected to the outside of the fixed plate 2, the output end of the first electric push rod 301 being connected to a first clamping plate 302, the first clamping plate 302 being rotatably connected to a linkage component, a second electric push rod 4 being fixedly connected to the top of one side of the workbench 1, the output end of the second electric push rod 4 being connected to a support plate 5, the top of the support plate 5 being fixedly connected to a fixed block 6, the outside of the fixed block 6 being fixedly connected to a first connecting pipe 7, and the inside of the fixed block 6 being provided with a second connecting pipe 13; the inside of the first clamping plate 302 is slidably connected to the inside of the workbench 1, and the input end of the first connecting pipe 7 is connected to the top of the workbench 1;

[0028] Specifically, the workbench 1 is composed of multiple testing components to facilitate various tests on the liquid cooling plate. The fixing plate 2 is composed of a connecting plate and a sliding rod to support the first clamping plate 302 in slidingly clamping the liquid cooling plate. The first electric push rod 301 is used to drive the first clamping plate 302 to drive the linkage component to clamp and fix the liquid cooling plate. The first clamping plate 302 is composed of a sliding rod and a clamping rod to facilitate clamping the liquid cooling plate. The linkage component is used to cooperate with the first clamping plate 302 to clamp the liquid cooling plate, thereby suppressing the torsion and deformation of the liquid cooling plate during the testing process and ensuring the accuracy of the flow resistance test data. The second electric push rod 4 is used to push the support plate 5 to insert the second connecting tube 13 into the outside of the interface of the liquid cooling plate. The fixing block 6 is used to connect the first connecting tube 7 and the support plate 5. The first connecting tube 7 is a telescopic sealing tube, which allows the second connecting tube 13 to be inserted into the liquid cooling plate after stretching. The fixing plate 2 and the first clamping plate 302 have rectangular grooves inside to facilitate the connection of the linkage component.

[0029] Reference Figure 1 and Figure 2 The linkage component includes a connecting rod 303, one end of which is rotatably connected to the inside of the first clamping plate 302, the middle part of which is rotatably connected to the inside of the fixed plate 2, and the end of the connecting rod 303 away from the first clamping plate 302 is rotatably connected to a second clamping plate 304, the inside of the second clamping plate 304 being slidably connected to the inside of the worktable 1.

[0030] Specifically, in this embodiment, the connecting rod 303 consists of a central rotating rod and two rotating rods, which facilitates the adjustment of the second clamping plate 304 according to the state of the first clamping plate 302. The second clamping plate 304 has a hole inside that allows the first electric push rod 301 to slide, so that the first electric push rod 301 can stop moving when the second clamping plate 304 slides, thereby avoiding the deviation of flow resistance test data caused by the change of liquid cooling plate position.

[0031] Example 2:

[0032] Reference Figure 3 The clamping mechanism 3 also includes a motor 305, which is externally fixedly connected to the outside of the fixed plate 2. The output end of the motor 305 is connected to a first gear 306. The tooth end of the first gear 306 is meshed with a second gear 307. The inside of the second gear 307 is fixedly connected to a threaded rod 308. The outside of the threaded rod 308 is threadedly connected to a third clamping plate 309. The two ends of the threaded rod 308 are rotatably connected to the inside of the worktable 1, and the middle part of the threaded rod 308 is rotatably connected to the inside of the fixed plate 2.

[0033] Specifically, in this embodiment, the fixing plate 2 has a hole on its exterior that allows the threaded rod 308 to rotate, and the third clamping plate 309 on one side of the motor 305 has a hole that allows the motor 305 to slide. The motor 305 is used to drive the third clamping plate 309 to clamp the liquid cooling plate. The first gear 306 and the second gear 307 are used to rotate the threaded rod 308. The threaded rod 308 is a bidirectional lead screw to facilitate the central clamping of the third clamping plate 309. Both ends and the center part of the threaded rod 308 are smooth round rods to facilitate only driving the third clamping plate 309 to slide. The motor 305 is started to drive the first gear 306 to rotate, thereby the first gear 306 meshes with the second gear 307 to rotate, and then the second gear 307 drives the threaded rod 308 to rotate. Furthermore, the threaded rod 308 drives the third clamping plate 309 to slide, thereby quickly clamping and fixing the liquid cooling plate on the support frame, achieving the effect of improving testing efficiency.

[0034] Example 3:

[0035] Reference Figure 1 , Figure 4 and Figure 5 Based on the above embodiments, this embodiment is used to solve the problem of incompatibility between the inlet and outlet connectors of the liquid cooling plate and the interfaces of liquid cooling plates of different specifications, and is achieved through the following solution.

[0036] A fixing tube 9 is fixedly connected inside the fixing block 6. A spring 11 is installed inside the fixing tube 9. A second washer 12 is installed at one end of the spring 11. The outer part of the second washer 12 is installed at one end of the second connecting tube 13 and is slidably connected to the inside of the fixing tube 9. A rail 8 is fixedly connected to the top of the workbench 1. The outer part of the rail 8 is slidably connected to the inside of the support plate 5. A first washer 10 is installed inside the fixing block 6 and the outer part of the first washer 10 is installed inside the second connecting tube 13.

[0037] Specifically, the interior of the fixing tube 9 has a U-shaped groove to facilitate fixing the second connecting tube 13. The exterior of the second gasket 12 has a limiting block, and the interior of the fixing tube 9 has a groove that fits the limiting block of the second gasket 12. The two work together to prevent the second gasket 12 from falling out of the fixing tube 9. The second gasket 12 and the first gasket 10 are used to ensure that the airtightness of the second connecting tube 13 meets the standard after installation. The spring 11 is used to prevent the second connecting tube 13 from falling off automatically due to loosening caused by external force, thereby achieving the effect of replacing the interface according to different liquid cooling plates.

[0038] Working principle: When the device is needed, the liquid cooling plate is placed on the top of the fixed plate 2, thereby activating the first electric push rod 301 to pull the first clamping plate 302 to clamp one side of the liquid cooling plate. Then, the first clamping plate 302 drives the connecting rod 303 to rotate and retract. Furthermore, the connecting rod 303 drives the second clamping plate 304 to clamp the other side of the liquid cooling plate, thus adapting to liquid cooling plates of different sizes and improving the convenience of processing.

[0039] When it is necessary to replace the corresponding second connecting pipe 13 according to the nozzle of the liquid cooling plate, the second connecting pipe 13 is pushed to drive the second gasket 12 to slide inside the fixed pipe 9. The second gasket 12 pushes the spring 11 to contract, thereby causing the sliders on both sides of the second connecting pipe 13 to slide to a state where the second connecting pipe 13 can rotate. The second connecting pipe 13 can be rotated further and then taken out for replacement. This allows for quick replacement of the matching connecting pipe, thereby improving the versatility and utilization of the testing device.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
