Description

Technical Field

[0001] This utility model relates to the field of heat dissipation liquid cooling plates, and more particularly to a heat dissipation liquid cooling plate for automobiles. Background Technology

[0002] Liquid cooling plates are a type of cooling material widely used in high-power electronic devices. Their main function is to remove heat generated inside the device through flowing coolant, keeping the system temperature within a safe operating range and preventing overheating that could lead to performance degradation or damage.

[0003] Existing technologies, such as the utility model with publication number CN111354719, disclose an optocoupler. This patent employs a first substrate with multiple rows and columns of pins formed on its first surface. The first surface also has longitudinally spaced inlet and outlet ends for coolant flow. A second surface of the first substrate has multiple mounting areas spaced laterally. At least one set of baffles is included, each baffle inserted into the gap between the pins corresponding to a spaced area. The spaced area is the region between adjacent mounting areas. Each set of baffles includes multiple longitudinally spaced baffles, each baffle having a notch facing the outlet end to prevent coolant from entering the gap between the pins within the notch. A second substrate is connected to the first surface of the first substrate, and a groove is formed on the second substrate, with inlet and outlet holes. This utility model's liquid-cooled heat sink improves heat dissipation efficiency and increases reusability.

[0004] The inventors discovered in daily use that while existing liquid cooling plates are very effective at heat dissipation, they cannot physically isolate heat sources within the battery pack. Liquid cooling plates essentially remove heat through conduction, rather than blocking heat generation. Therefore, heat from the battery pack continues to transfer to the liquid cooling plate, making overall heat control difficult. As the heat dissipation process continues, the coolant gradually heats up during its flow. If the coolant temperature becomes too high, it will be unable to effectively remove heat, leading to heat accumulation and a negative effect. This, in turn, affects the heat dissipation performance of the liquid cooling plate, further exacerbating the heat transfer problem.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

A limiting groove is formed on the inner wall of the heat dissipation plate, and the limiting groove is adapted to the limiting plate.

[0022] This invention provides a liquid cooling plate for automobiles. While existing liquid cooling plates are highly effective at heat dissipation, they cannot physically isolate heat sources within the battery pack. Liquid cooling plates essentially remove heat through conduction, rather than blocking heat generation. Therefore, heat from the battery pack continues to transfer to the liquid cooling plate, making overall heat control difficult. As the heat dissipation process continues, the coolant gradually heats up during flow. If the coolant temperature is too high, it cannot effectively remove heat, leading to heat accumulation and a negative effect.

The screw 308 abuts against the cooling plate 1. A sliding plate 303 is slidably connected to the inner wall of the sleeve plate 302. Several springs 311 are provided inside the sleeve plate 302. The two ends of the springs 311 are fixedly connected to the sleeve plate 302 and the sliding plate 303, respectively. When the battery pack needs to be isolated, the sleeve plate 302 is pulled to move, which drives the slider 304 to move. The slider 304 slides on the inner wall of the groove 301. The sleeve plate 302 drives the connecting plate 307 to move, and the connecting plate 307 drives the screw 308 to move. Then the battery pack is placed between the two sleeve plates 302. Then the slide plate 303 abuts against the contact surface. The slide plate 303 drives the spring 311 to contract. Then the rebound force of the spring 311 drives the slide plate 303 to abut against the contact surface. Then the sleeve plate 302 and the slide plate 303 isolate the battery pack. An auxiliary rod 310 is fixedly connected inside the sleeve plate 302. The auxiliary rod 310 is slidably connected to the slide plate 303. The spring 311 is sleeved on the arc surface of the auxiliary rod 310. The auxiliary rod 310 can limit the spring 311 to prevent deformation during use and improve its service life. A limiting rod 306 is fixedly connected inside the slide groove 301, and the limiting rod 306 is slidably connected to the slider 304. The limiting rod 306 can limit the slider 304 to prevent it from shifting when sliding on the inner wall of the slide groove 301. Several levers 309 are fixedly connected to the arc surface of the screw 308, and these levers 309 are evenly distributed on the screw 308. When it is necessary to rotate the screw 308, the levers 309 can be rotated directly, causing the screw 308 to move. The levers 309 make rotating the screw 308 more convenient. Isolation pads 305 are fixedly connected to both sides of the sleeve plate 302. The isolation pads 305 have a rectangular cross-section.

A limiting groove 44 is formed on the inner wall of the heat dissipation plate 41, and the limiting groove 44 is adapted to the limiting plate 45. When the heat dissipation plate 41 needs to be installed and used, it is pulled to move, causing the elastic block to move. Then, the heat dissipation plate 41 is aligned with the connecting groove 46, and then inserted into the connecting groove 46. The connecting groove 46 then compresses and contracts the extrusion block 42. After moving to the appropriate position, the extrusion block 42 is locked into the slot 43 for fixation.

[0036] The working principle of the liquid cooling plate for automobiles provided by this utility model is as follows: When the battery pack needs to be isolated, the sleeve plate 302 is pulled to move, which drives the slider 304 to move. The slider 304 slides on the inner wall of the groove 301. The sleeve plate 302 drives the connecting plate 307 to move, and the connecting plate 307 drives the screw 308 to move. Then, the battery pack is placed between the two sleeve plates 302. Then, the sliding plate 303 abuts against the contact surface. The sliding plate 303 drives the spring 311 to contract. Then, the rebound force of the spring 311 drives the sliding plate 303 to abut against the contact surface. The sleeve plate 302 and the slide plate 303 isolate the battery panel. The auxiliary rod 310 can limit the spring 311 to prevent deformation during use and improve the service life of the spring 311. The limiting rod 306 can limit the slider 304 to prevent the slider 304 from deviating when sliding on the inner wall of the slide groove 301. When it is necessary to rotate the screw 308, the handle 309 can be rotated directly. The handle 309 drives the screw 308 to move, making it easier to rotate the screw 308. The isolation pad 305 can isolate heat to prevent heat diffusion when a single battery pack is heated.

[0037] When the heat sink 41 needs to be installed and used, pull the heat sink 41 to move it. The heat sink 41 drives the elastic block to move. Then, align the heat sink 41 with the connecting groove 46 and insert the heat sink 41 into the connecting groove 46. Then, the connecting groove 46 squeezes and shrinks the pressing block 42. After moving to the appropriate position, the pressing block 42 is locked into the slot 43 for fixation. The limiting plate 45 is inserted into the limiting groove 44 for limiting. The aluminum material can increase the heat dissipation efficiency of the heat sink 41. The aluminum plate has strong thermal conductivity.
