Description
Split-type DC charging pile liquid cooling heat reduction structure Technical Field
[0001] This utility model relates to the technical field of split-type DC charging piles, and in particular to the liquid cooling structure for split-type DC charging piles. Background Technology
[0002] A split-type DC charging pile is a DC charging device that separates the power module (rectifier cabinet) from the charging terminal (gun) of a traditional integrated charging pile. It achieves efficient charging through modular structure and flexible layout. When the charging pile is in use, it needs to be cooled by the liquid cooling structure inside the back.
[0003] Liquid cooling structure is a system that achieves efficient heat dissipation through the circulation of liquid cooling medium, mainly used to solve the heat problem generated during high-power charging.
[0004] A search revealed that Chinese patent announcement number CN222116574U discloses a split-type liquid-cooled DC supercharging pile. The pile body contains an insulation plate, dividing the inner cavity into an installation cavity and a heat dissipation cavity. Multiple layers of mounting brackets are fixed within the installation cavity, and the DC supercharging module is mounted on these brackets. The liquid cooling assembly includes cooling pipes, heat dissipation pipes, a circulation pump, and a heat exchange fan. The cooling pipes are mounted at the bottom of each layer of brackets, and the heat dissipation pipes are laid within the heat dissipation cavity. The two are connected end-to-end to form a circulation pipeline. The circulation pump is mounted on the pipeline, and the heat exchange fan is mounted at the air inlet or exhaust outlet. The pile also includes a charging gun and charging cable mounted outside the pile body. This utility model has a reasonable structure, good cooling effect, excellent heat dissipation performance, and strong practicality. It can effectively solve the problems existing in current products and has broad market application prospects.
[0005] In the existing patent literature, the cooling network pipe, heat dissipation network pipe, circulation pump and heat exchange fan are used together to dissipate heat from the charging pile. However, the heat dissipation network pipe needs to be inspected after long-term use. Since the heat dissipation network pipe is fixed in the heat dissipation cavity on the back of the machine, it is difficult for the staff to inspect the heat dissipation network pipe.

[0033] Compared with the prior art, the beneficial effects of this utility model are:
[0034] By setting up convenient maintenance components, pushing the baffle, the thrust pushes the slide bar to move in the slot, causing the baffle to move inside the fixed frame via the slide bar. This causes the baffle to move through the vertical hole, gradually exposing the inside of the fixed frame and exposing the inner heat dissipation pipe to the external environment. This makes it easier for maintenance personnel to maintain and repair the heat dissipation pipe inside the fixed frame, solving the problems in the existing technology. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0046] 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.
[0047] Given that the existing patent literature describes the use of cooling network pipes, heat dissipation network pipes, circulation pumps, and heat exchange fans to dissipate heat from charging piles, the heat dissipation network pipes require maintenance after long-term use. However, since the heat dissipation network pipes are fixed inside the heat dissipation cavity on the back of the device, it is difficult for staff to inspect them.
[0048] As shown in Figures 1-3, this utility model embodiment provides a split-type DC charging pile liquid cooling structure, including:
[0049] Body 11;
[0050] Heat pipe 15 is fixed to the back side of the body 11;
[0051] Also includes:
[0052] Charging gun 12 is located on one side of the body 11;
[0053] Water pump 13 is fixed inside the lower side of the body 11;
[0054] Cooling pipe 14 is located inside the body 11 at the center and above and below;
[0055] The body 11 is used to connect components such as the charging gun 12. The charging gun 12 is used to charge the vehicle. The water pump 13 is used to circulate the coolant inside the cooling pipe 14 and the heat dissipation pipe 15. The cooling pipe 14 and the heat dissipation pipe 15 are used together to dissipate heat from the body 11.
[0056] Convenient repair kit 20;
[0057] Convenient repair component 20 includes:
[0058] The fixing frame 21 is fixed to the back of the body 11;
[0059] Baffle 22 is snapped into the inner side of the fixed frame 21;
[0060] A vertical hole 23 is provided on one side of the fixing frame 21;
[0061] The card slot 24 is located at the bottom inner side of the fixing frame 21;
[0062] The slide bar 25 is fixed to the bottom end of the baffle 22 and slidably connected to the inside of the slot 24;
[0063] The fixed frame 21 is used to connect the baffle 22. The baffle 22 blocks the heat dissipation pipe 15 inside the fixed frame 21. The vertical hole 23 is used for the movement of the baffle 22. The slot 24 is used for the connection and movement of the slide rod 25. The slide rod 25 is used for the movement of the baffle 22.
[0064] One end of the baffle 22 extends to the inner side of the outer end of the vertical hole 23, and the outer end of the baffle 22 is fixedly connected to the limit plate 26.
[0065] A groove 27 is provided at the other end of the inner side of the fixed frame 21. A protrusion 28 is snapped into the inner side of the groove 27. One end of the protrusion 28 is fixedly connected to the other end of the baffle 22.
[0066] The limiting plate 26 and the protruding rod 28 are used together to prevent the baffle 22 from separating from the fixed frame 21. The groove 27 is used to engage the protruding rod 28. When the baffle 22 and the inner side of the fixed frame 21 are closed, the limiting plate 26 is in contact with the outer side of the body 11, and the protruding rod 28 is engaged with the groove 27. When the baffle 22 is pushed, the baffle 22 pushes the limiting plate 26 away from the fixed frame 21, so that the protruding rod 28 leaves the groove 27 and engages with the fixed frame 21 next to the vertical hole 23, thereby preventing the baffle 22 from separating from the fixed frame 21.
[0067] A connecting plate 29 is fixedly connected to the upper and lower sides of one side of the limiting plate 26. The connecting plate 29 is attached to one side of the body 11, and a limiting rod 291 passes through the attachment point.
[0068] A limiting hole 292 is provided at the through point of the connecting plate 29, the body 11 and the limiting rod 291, and the limiting rod 291 is threadedly connected to the limiting hole 292;
[0069] The connecting plate 29 is used to open the limiting hole 292, the limiting rod 291 is used to limit the baffle 22 when closed, and the limiting hole 292 is used for the insertion and rotation of the limiting rod 291. When the baffle 22 is closed with the inner side of the fixed frame 21, the limiting plate 26 is in contact with the outer side of the machine body 11, so that the limiting holes 292 on the surfaces of the two are aligned. The limiting rod 291 is rotated and inserted into the limiting hole 292, so that the limiting rod 291 limits the baffle 22 when closed.
[0070] Before use, the baffle 22 and the inner side of the fixed frame 21 are in a closed state, and the limiting rod 291 and the limiting hole 292 are in a tight connection state. When the component is used, the limiting rod 291 is rotated with a tool so that the limiting rod 291 is separated from the limiting hole 292 through the thread. The baffle 22 is pushed by hand, and the thrust pushes the slide rod 25 to move in the slot 24 through the baffle 22, so that the baffle 22 moves inside the fixed frame 21 through the slide rod 25, causing the baffle 22 to move through the vertical hole 23. At the same time, the baffle 22 drives the protrusion 28 to leave the groove 27, and the protrusion 28 is engaged with the fixed frame 21 on the side of the vertical hole 23 to prevent the baffle 22 from separating from the fixed frame 21, so that the inner side of the fixed frame 21 is gradually exposed, thereby exposing the inner heat dissipation pipe 15 to the external environment, which makes it easier for maintenance personnel to maintain and repair the heat dissipation pipe 15.
[0071] Specifically, as shown in Figures 1-2 and 4-5, it also includes an auxiliary limiting component 30;
[0072] The auxiliary limit component 30 includes:
[0073] The fixing rod 31 is fixed to the middle of the outer end of the fixing frame 21;
[0074] The slot 32 is formed on the inner side of the fixing rod 31;
[0075] The connecting block 33 is fixed to the center of one side of the outer side of the baffle 22 and is slidably connected to the slot 32;
[0076] The fixing rod 31 is used to open the slot 32, the slot 32 is used to connect and move the connecting block 33, and the connecting block 33 is used to open the insertion hole 35.
[0077] A set of square holes 34 are provided on the upper and lower sides of the inner side of the slot 32, and a plug-in hole 35 is provided on the surface of the connecting block 33;
[0078] The insertion hole 35 is aligned with the square hole 34, and an insertion plate 36 is inserted between the inner sides of the two. A limit block 37 is fixedly connected to the top of the insertion plate 36.
[0079] The square hole 34 and the insertion hole 35 are used together for the insertion of the insertion plate 36. The insertion plate 36 can limit the movement of the baffle 22. The limiting block 37 limits the insertion of the insertion plate 36 to prevent the insertion plate 36 from separating from the square hole 34 and the insertion hole 35. Pushing the baffle 22, the baffle 22 drives the connecting block 33 to move within the slot 32. When the baffle 22 moves to the appropriate position, the insertion hole 35 and the square hole 34 are aligned. The insertion plate 36 is then inserted into the insertion hole 35 and the square hole 34, thereby limiting the movement of the baffle 22 and preventing the baffle 22 from causing injury to maintenance personnel due to random movement.
[0080] Before use, the baffle 22 is not moved. When using the component, push the baffle 22 by hand. The baffle 22 drives the connecting block 33 to move in the slot 32 through the slide rod 25. When the baffle 22 moves to the appropriate position, the insertion hole 35 and the square hole 34 are aligned. Insert the insertion plate 36 into the insertion hole 35 and the square hole 34 by hand, so that the insertion plate 36 and the limiting block 37 limit the baffle 22 after it has moved, preventing the baffle 22 from causing injury to the maintenance personnel due to random movement.
[0081] 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.
