Description
Technical Field
[0001] This utility model relates to the technical field of heat dissipation fins for charging piles, and in particular to a heat-reducing structure with adjustable heat dissipation fins for split-type DC charging piles. Background Technology
[0002] A DC charging pile is a charging device that provides DC power to electric vehicles. It can directly convert AC power from the power grid into DC power and output high voltage and high current to quickly charge the electric vehicle battery.
[0003] The heat dissipation fins of a charging pile are metal structures used to enhance heat dissipation. They are usually installed inside or outside the charging pile to increase the heat dissipation area and accelerate heat transfer, helping the charging pile maintain a stable temperature when working under high load.
[0004] However, most existing charging pile heat dissipation fins adopt a fixed spacing design. The heat generation of charging piles varies greatly under different power levels (such as 60kW fast charging vs. 200kW supercharging). Fixed fins have the problem of excessive heat dissipation under low load and insufficient heat dissipation under high load. Utility Model Content
[0005] The purpose of this invention is to provide a split-type DC charging pile with adjustable heat dissipation fins to solve the problems mentioned in the background art.
[0006] The technical solution adopted in this utility model is:
[0007] The split-type DC charging station features an adjustable heat dissipation fin structure, including:
[0008] Cooling components;
[0009] The heat-reducing component includes:
[0010] Fixed frame;
[0011] The heat dissipation fins are set with thirteen fins, which slide inside the fixed frame;
[0012] Adjustment component, the adjustment component comprising:
[0013] The limiting groove is located inside the upper part of the fixed frame and extends through the fixed frame;
[0014] The motor is fixed to one side of the fixed frame;
[0015] A rotating column is fixed to the output end of the motor, and the rotating column rotates through the fixed frame.
[0016] There are thirteen adjusting grooves in total, which are evenly distributed on the outer surface of the rotating column. One of them is located in the middle of the rotating column, and the rest are symmetrically distributed outwards.
[0017] There are thirteen limiting posts in total, which are fixed to the rear side of the corresponding heat dissipation fins, and the limiting posts penetrate the limiting groove.
[0018] Optionally, mounting holes are provided on both sides of the fixing frame, and the mounting holes are bolted to the split DC charging pile.
[0019] Optionally, the end of the limiting post is slidably placed inside the corresponding adjustment groove, and sliding holes are provided on the upper and lower sides of the outer surface of the heat dissipation fin.
[0020] Optionally, a fixing platform is fixed to the outer surface of the motor, and one side of the fixing platform is fixed to the outer surface of the fixing frame.
[0021] Optionally, a limiting rod passes through the sliding hole, and the two limiting rods are fixed at the upper and lower ends inside the fixed frame.
[0022] Optionally, the rotating column is located on the outer side of the heat dissipation fins, and the symmetrically opened adjustment slots have the same diffusion angle.
[0023] Optionally, extension components may also be included;
[0024] The extension component includes:

[0028] Optionally, a baffle is fixed to one side of the extension plate, and the diameter of the baffle is larger than the opening diameter of the mounting groove.
[0029] Compared with the prior art, the beneficial effects of this utility model are:
[0030] By using heat dissipation and adjustment components, users can adjust the spacing of the heat sink fins to suit different charging power requirements. During high-power charging, an external controller starts the motor, which drives the rotating column counter-clockwise, causing the adjustment slot to rotate to the side with a larger spacing. Simultaneously, the adjustment slot drives the limiting column to widen the spacing. With the limiting rod in place, the limiting column causes the heat sink fins to widen their spacing outwards. With a wider spacing, fan airflow can more easily penetrate the fin array, reducing wind resistance and eddies, and improving the convective heat transfer coefficient. During low-power charging, the external controller starts the motor, which drives the rotating column clockwise, causing the adjustment slot to rotate to the side with a smaller spacing. Similarly, the rotation of the adjustment slot causes the limiting column to narrow the spacing, and also causes the heat sink fins to narrow their spacing. With a narrower fin spacing, the fan can maintain sufficient heat dissipation even at low speeds, avoiding high-speed noise and reduced energy efficiency. By dynamically adjusting the fin spacing to adapt to different charging power requirements, heat dissipation efficiency can be significantly improved, energy consumption and noise reduced, achieving a precise balance between heat dissipation efficiency and energy consumption, thus solving problems in existing technologies.

Therefore, they should not be construed as limitations on this utility model.
[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0042] Given the current technology, most existing charging pile heat dissipation fins adopt a fixed spacing design. The heat generation of charging piles varies greatly under different power levels (such as 60kW fast charging vs. 200kW supercharging). Fixed fins have the problem of excessive heat dissipation under low load and insufficient heat dissipation under high load.
[0043] like Figure 1-3 As shown, this embodiment of the utility model provides a split-type DC charging pile with adjustable heat dissipation fins for heat reduction, including...
[0044] Cooling component 1;
[0045] Cooling component 1 includes:
[0046] Fixed frame 11;
[0047] The heat dissipation fins 12 are provided in thirteen parts and are slidably placed inside the fixed frame 11;
[0048] Mounting holes 13 are provided on both sides of the fixed frame 11, and the mounting holes 13 are bolted to the split DC charging pile.
[0049] Adjustment component 2, adjustment component 2 includes:
[0050] The limiting groove 21 is opened inside the upper end of the fixed frame 11 and penetrates through the fixed frame 11;
[0051] Motor 22 is fixed to one side of the fixed frame 11;
[0052] The rotating column 23 is fixed at the output end of the motor 22, and the rotating column 23 rotates through the fixed frame 11.
[0053] There are thirteen adjusting grooves 24, which are evenly distributed on the outer surface of the rotating column 23, with one groove in the middle of the rotating column 23 and the rest symmetrically distributed outwards.
[0054] There are thirteen limiting posts 25, which are fixed to the rear side of the corresponding heat dissipation fins 12, and the limiting posts 25 penetrate the limiting grooves 21.
[0055] The fixing frame 11 serves as a support frame for the heat dissipation fins 12, providing structural stability. The heat dissipation fins 12 are core heat dissipation components that accelerate heat dissipation by increasing their surface area. The mounting holes 13 are used to bolt the fixing frame 11 onto the charging pile housing, ensuring the overall structural stability of the heat dissipation components and the charging pile.
[0056] The limiting groove 21 provides a sliding track for the limiting post 25, limiting its range of motion and ensuring that the adjustment direction of the heat dissipation fins 12 is controllable. The motor 22 provides a power source to drive the rotating post 23 to rotate clockwise and counterclockwise, thereby realizing the adjustment of the spacing of the heat dissipation fins 12. The rotating post 23 transmits the rotational power of the motor 22 to drive the adjustment groove 24 to rotate, and then drives the heat dissipation fins 12 to expand or contract through the limiting post 25. The adjustment groove 24 is a key transmission structure. Through the rotation of the rotating post 23, the limiting post 25 is driven to slide along the limiting groove 21, thereby realizing the adjustment of the spacing of the heat dissipation fins 12. The limiting post 25 connects the heat dissipation fins 12 and the adjustment groove 24, converting the rotational motion into the linear sliding of the fins.
[0057] The end of the limiting post 25 is slidably placed inside the corresponding adjustment slot 24. Sliding holes 26 are opened on the upper and lower sides of the outer surface of the heat dissipation fin 12. A fixed platform 221 is fixed on the outer surface of the motor 22, and one side of the fixed platform 221 is fixed on the outer surface of the fixed frame 11. A limiting rod 27 passes through the sliding hole 26, and the two limiting rods 27 are fixed on the upper and lower ends inside the fixed frame 11. The rotating post 23 is located on the outer side of the heat dissipation fin 12, and the symmetrically opened adjustment slots 24 have the same diffusion angle.
[0058] The sliding hole 26 provides guidance for the limiting rod 27, ensuring that the fins move in parallel during adjustment. The limiting rod 27 is fixed at the upper and lower ends of the fixed frame 11 to limit the sliding range of the fins and prevent derailment. The fixed platform 221 enhances the installation stability of the motor 22.
[0059] During use, users can adjust the spacing of the heat dissipation fins 12 to suit different charging power levels. For high-power charging, the external controller starts the motor 22, which drives the rotating column 23 to rotate counter-clockwise, causing the adjustment slot 24 to rotate to the side with the larger spacing. Simultaneously, the adjustment slot 24 drives the limiting column 25 to widen the spacing. With the connection of the limiting rod 27, the limiting column 25 drives the heat dissipation fins 12 to widen the spacing outwards. After the spacing widens, the fan airflow can more easily penetrate the fin array, reducing wind resistance and eddies, and improving the convection heat transfer coefficient. For low-power charging, the spacing is adjusted by... The external controller starts the motor 22, which drives the rotating column 23 to rotate clockwise, causing the adjustment slot 24 to rotate to the side with a smaller spacing. Similarly, the rotation of the adjustment slot 24 drives the limiting column 25 to reduce the spacing, and also drives the heat dissipation fins 12 to reduce the spacing. After the heat dissipation fins 12 reduce the spacing, the fan can maintain sufficient heat dissipation even when running at low speed, avoiding high-speed noise and reducing energy efficiency. By dynamically adjusting the fin spacing to adapt to different charging power requirements, the heat dissipation efficiency can be significantly improved, energy consumption and noise can be reduced, and a precise balance between heat dissipation efficiency and energy consumption can be achieved, solving the problems in the existing technology.
[0060] Specifically, such as Figure 1-4 As shown,
[0061] Extension component 3;
[0062] Extension component 3 includes:
[0063] The mounting slot 31 is located inside the heat dissipation fin 12, and the mounting slot 31 is convex in shape.
[0064] There are seven springs 32 in total, which are fixed at equal intervals inside the mounting slots 31.
[0065] An extension plate 33 is fixed to one end of a spring 32, and one end of the extension plate 33 is inserted into the mounting groove 31.
[0066] A baffle 34 is fixed on one side of the extension plate 33, and the diameter of the baffle 34 is larger than the opening diameter of the mounting groove 31.
[0067] The mounting groove 31 serves as the mounting carrier for the spring 32 and the extension plate 33, providing fixation and guidance. The spring 32 provides elastic force to push the extension plate 33 outward, increasing the surface area of the heat dissipation fins 12. The extension plate 33 directly expands the effective surface area of the heat dissipation fins 12, enhancing the contact area with air and improving heat dissipation efficiency. The baffle 34 limits the maximum extension stroke of the extension plate 33, preventing it from coming out of the mounting groove 31.
[0068] In use, regardless of the type of charging station the heat sink 12 is installed on, the spring 32 will push the extension plate 33 to move outward under the action of the spring force. The expansion of the extension plate 33 increases the effective heat dissipation area of the heat sink 12, accelerates heat transfer, and improves the heat dissipation and cooling effect. The spring force of the spring 32 can automatically adjust the maximum extent to which the extension plate 33 can be expanded. The design of expanding the surface area of the heat sink 12 by pushing the extension plate 33 with the spring 32 dynamically increases the surface area and improves the convective heat transfer efficiency.
[0069] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
