Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, and in particular to an arch-bridge type reinforced wide-channel finned liquid cooling plate. Background Technology

[0002] A liquid cooling plate is a thermal management system component used in batteries, battery packs, or electronic devices. It is typically made of metal and contains a coolant. Its main function is to remove heat generated by the device or battery through liquid circulation, maintaining the temperature within a safe range and effectively preventing overheating. It is widely used in electric vehicles, energy storage systems, and high-performance electronic devices, and is a key component for ensuring stable operation and extending the lifespan of these devices.

[0003] In actual use, the internal strength of existing liquid cooling plates is relatively weak. During long-term heat exchange and circulation, problems such as deformation, expansion or cracking may occur, affecting the normal operation of the liquid cooling system and potentially threatening the overall safety of the equipment. At the same time, the liquid cooling plate cannot effectively withstand the internal pressure changes, which may lead to battery bulging. Utility Model Content

[0004] Based on the technical problem of low internal structural strength of existing liquid cooling plates, this utility model proposes an arch-bridge type reinforced wide-channel finned liquid cooling plate.

[0005] This utility model proposes an arch-bridge type reinforced wide-channel finned liquid cooling plate, comprising a liquid cooling plate, a lower substrate welded to the top of the liquid cooling plate, and an upper substrate welded to the bottom of the liquid cooling plate. The liquid cooling plate, the lower substrate, and the upper substrate form an integral body with a pre-reserved flow channel cavity inside. Fins are fixedly installed inside the flow channel cavity. Horizontal beams are evenly spaced in the horizontal direction of the flow channel cavity, and the horizontal beams enhance the horizontal stress strength of the battery pack. Vertical beams are alternately spaced in the vertical direction of the flow channel cavity, and the vertical beams enhance the vertical stress strength of the battery pack.

[0006] Preferably, the top surface of the transverse beam is provided with an arc-shaped groove, and there is a protrusion between the two arc-shaped grooves.

[0007] The above technical solution utilizes the protrusions on the transverse beam to support the lower substrate, and the bottom of the transverse beam to support the lower substrate, thereby strengthening the interior of the flow channel cavity, improving the overall structural strength, and reducing battery bulging.

[0008] Preferably, the arc-shaped groove has a first transition section in the liquid inlet direction, and the coolant flows in along the arc surface of the first transition section.

[0009] Through the above technical solution, the coolant can circulate normally when it flows through the transverse beam by opening the arc groove, and the flow of coolant can be guided. The first transition section can buffer and stabilize the incoming coolant.

[0010] Preferably, the arc-shaped groove has a second transition section in the liquid outlet direction, and the coolant flows out along the inclined surface of the second transition section.

[0011] The above technical solution utilizes a second transition section to prevent air bubbles from forming when the coolant flows out, thereby reducing noise generated during liquid cooling and minimizing material corrosion.

[0012] Preferably, an inlet and an outlet are respectively provided on one side of the upper substrate, and both the inlet and the outlet are in communication with the flow channel cavity.

[0013] The above technical solution allows coolant to be introduced through the inlet and discharged through the outlet, facilitating heat exchange and cooling of the battery pack. It also makes it easy to replace and collect the coolant used to cool the battery pack, enabling its recycling.

[0014] Preferably, one end of the vertical beam closest to the liquid inlet and the liquid outlet is fixedly connected to the inner wall of the liquid cooling plate on the side closest to the liquid inlet, and the other end of the vertical beam closest to the liquid inlet and the liquid outlet is spaced apart from the inner wall of the other side of the liquid cooling plate by a certain distance.

[0015] The above technical solution utilizes the top and bottom of the vertical beams to support the lower substrate and the lower plate, respectively. The alternating vertical beams allow the coolant to flow along the vertical beams within the gap between the vertical beams and the cooling plate, forming an overall "bow"-shaped circulation flow, which facilitates more comprehensive cooling of one side of the battery pack.

[0016] Preferably, the two ends of the fin are in contact with the bottom surface of the lower substrate and the top surface of the upper substrate, respectively, and the fin is disposed in the partition between the transverse beam and the vertical beam.

[0017] By using the above technical solutions, the heat exchange area is increased by utilizing fins, thereby improving the efficiency of heat exchange and making the coolant more evenly distributed in the cooling system, thus improving the cooling efficiency.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By setting up horizontal beams and staggered vertical beams, the lower and upper substrates are supported, thereby strengthening the interior of the flow channel cavity, improving the overall structural strength, and reducing battery bulging.

[0020] 2. By setting up an arc-shaped groove, the coolant can circulate normally when flowing through the transverse beam and the flow of the coolant is guided. The first transition section can buffer and stabilize the coolant, and the second transition section can prevent air bubbles from being generated when the coolant flows out, thereby reducing the noise generated during liquid cooling and reducing material corrosion.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-7An arch-bridge type reinforced wide flow channel finned liquid cooling plate includes a liquid cooling plate 1, a lower substrate 2 welded to the top of the liquid cooling plate 1, an upper substrate 3 welded to the bottom of the liquid cooling plate 1, and a flow channel cavity 4 reserved inside the integral formed by the liquid cooling plate 1, the lower substrate 2 and the upper substrate 3, and fins 5 fixedly installed inside the flow channel cavity 4.

[0031] To enhance the lateral strength of the battery pack, transverse beams 6 are provided at equal intervals in the lateral direction of the flow channel cavity 4. The transverse beams 6 strengthen the lateral force strength of the battery pack. Vertical beams 7 are provided alternately at equal intervals in the vertical direction of the flow channel cavity 4. The vertical beams 7 strengthen the vertical force strength of the battery pack.

[0032] The top surface of the transverse beam 6 is provided with an arc-shaped groove 8, and there is a protrusion 61 between the two arc-shaped grooves 8. The protrusion 61 on the transverse beam 6 supports the lower substrate 2, and the bottom of the transverse beam 6 supports the upper substrate 3, thereby strengthening the interior of the flow channel cavity 4, improving the overall structural strength, and reducing battery bulging.

[0033] To reduce the flow resistance of the coolant from the transverse beam 6, a first transition section 11 is provided in the inlet direction of the arc-shaped groove 8. The first transition section 11 is preferably arc-shaped, but can also be a slope. The coolant flows in along the arc surface of the first transition section 11, allowing it to be guided along this surface and avoiding the resistance of the cross-section formed by the perpendicular angle between the transverse beam 6 and the substrate. The arc-shaped groove 8 ensures normal circulation of the coolant as it flows through the transverse beam 6 and guides its flow. The first transition section 11 buffers and stabilizes the incoming coolant.

[0034] To prevent cavitation when the coolant flows through the arc-shaped groove 8 at high speed, a second transition section 12 is provided in the outlet direction of the arc-shaped groove 8. The second transition section 12 is preferably a trapezoidal block, with its long side aligned with the right-angle side of the transverse beam 6 and its short side aligned with the thickness of the bottom edge of the fin 5. The coolant flows out along the arc surface of the second transition section 12. The second transition section 12 prevents air bubbles from forming when the coolant flows out, thereby reducing noise generated during liquid cooling and reducing material corrosion. Because high-speed water flow can cause local pressure to fall below the saturated vapor pressure, cavitation bubbles can collapse and impact the substrate. Especially when the transverse beam 6 is used upside down with the substrate or as a vertical side plate, bubbles will form at the right-angle side of the connection between the transverse beam 6 and the substrate. This will not only cause cavitation on the substrate, but also generate pulsating pressure due to turbulence, which may cause structural resonance of the entire battery pack.

[0035] The upper substrate 3 has an inlet 9 and an outlet 10 on one side, both of which are connected to the flow channel cavity 4. Coolant is introduced through the inlet 9 and discharged through the outlet 10, facilitating heat exchange and cooling of the battery pack. This also allows for easy replacement and collection of the coolant for recycling. One end of the vertical beam 7 closest to the inlet 9 and outlet 10 is fixedly connected to the inner wall of the liquid cooling plate 1 near the inlet 9, while the other end of the vertical beam 7 is spaced apart from the inner wall of the other side of the liquid cooling plate 1. A vertical beam 7 supports the lower substrate 2 and the upper substrate 3 at its top and bottom, respectively. The alternating vertical beams 7 allow the coolant to flow along the vertical beams 7 within the gap between the vertical beams 7 and the cooling plate, forming an overall "bow"-shaped circulation flow. This facilitates more comprehensive cooling of one side of the battery pack. The two ends of the fins 5 are in contact with the bottom surface of the lower substrate 2 and the top surface of the upper substrate 3, respectively. The fins 5 are disposed in the partition between the horizontal beam 6 and the vertical beam 7. The fins 5 increase the heat exchange area, thereby improving the heat exchange efficiency and allowing the coolant to be distributed more evenly in the cooling system, thus improving cooling efficiency.

[0036] By setting up horizontal beams 6 and staggered vertical beams 7, the lower substrate 2 and upper substrate 3 are supported, thereby strengthening the interior of the flow channel cavity 4, improving the overall structural strength, and reducing battery bulging. By setting up arc-shaped grooves 8, the coolant can circulate normally when flowing through the horizontal beams 6, and the flow of the coolant is guided. By setting up the first transition section 11, the coolant can be buffered and stabilized. By setting up the second transition section 12, air bubbles are prevented when the coolant flows out, thereby reducing the noise generated during liquid cooling and reducing material corrosion.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
