[0039] Please refer to Figures 1 to 6 , the heat dissipation device 10 of the charging pile in an embodiment is used to dissipate heat from the charging module 20 of the charging pile. The heat dissipation device 10 of the charging pile includes a bracket 100, a liquid cooling mechanism 200 and an air cooling mechanism 300. The bracket 100 is sleeved outside the charging module 20. The bracket 100 has a hollow cavity 101 for accommodating the charging module 20. The cavity wall of the hollow cavity 101 is provided with a cooling flow channel 102 for the cooling medium to flow. The liquid cooling mechanism 200 is connected to the bracket 100 and communicates with the cooling flow channel 102. The air cooling mechanism 300 is connected to the liquid cooling mechanism 200; wherein, the cooling medium can flow between the liquid cooling mechanism 200 and the cooling flow channel 102, and the air cooling mechanism 300 is used to assist in cooling the cooling flow channel 102.

[0040] It should be noted that the charging module 20 is one of the core components of the charging pile, mainly used to convert the input alternating current or direct current into direct current suitable for charging the electric vehicle battery, and can accurately control the charging current and voltage. During the operation of the charging pile, due to the energy conversion and current transmission during the charging process, a large amount of heat will be generated by the charging module 20 of the charging pile. Through the flow of the cooling medium between the liquid cooling mechanism 200 and the cooling channel 102 of the bracket 100, the cooling medium can exchange heat with the liquid cooling mechanism 200 to cool down, and at the same time, the air cooling mechanism 300 can assist the cooling channel 102 to quickly cool down by air cooling.

[0041] For the above-mentioned heat dissipation device 10 of the charging pile, since the bracket 100 is sleeved outside the charging module 20, through the flow of the cooling medium between the liquid cooling mechanism 200 and the cooling channel 102 of the bracket 100, the bracket 100 can continuously absorb the heat emitted by the charging module 20 to cool down the charging module 20; at the same time, the air cooling mechanism 300 can blow a cooling air flow to the bracket 100 to assist the cooling channel 102 to quickly cool down by air cooling, realizing fast and efficient cooling and heat dissipation of the charging module 20, keeping the working temperature of the charging module 20 within the normal range, and facilitating the stable operation of the charging module 20.

[0042] In the embodiment of the present application, the bracket 100 is a component sleeved outside the charging module 20. The bracket 100 has a hollow cavity 101, and the hollow cavity 101 can be in the shape of a hollow cylinder, a hollow elliptical cylinder or other shapes; the cavity wall of the hollow cavity 101 is provided with a cooling channel 102 for the flow of the cooling medium, and the cooling channel 102 can be in the shape of a circular ring, an elliptical ring or other shapes.

[0043] In the embodiment of the present application, the liquid cooling mechanism 200 is a component used to deliver the cooling medium to the cooling channel 102 of the bracket 100 and receive the cooling medium output from the cooling channel 102. The liquid cooling mechanism 200 can adopt various structural forms. For example, the liquid cooling mechanism 200 includes components such as a driving pump and a controller. The driving pump is used to drive the cooling medium to circulate in the system, and the controller is used to distribute and manage the flow of the cooling medium.

[0044] In the embodiment of the present application, the air cooling mechanism 300 is a component used to blow a cooling air flow to the bracket 100 to assist the cooling channel 102 to cool down. The air cooling mechanism 300 can adopt various structural forms. For example, the air cooling mechanism 300 includes components such as a fan and an air duct. The cooling air flow is generated by the rotation of the fan, and the cooling air flow is guided to the position where heat dissipation is required through the air duct.

[0045] Specifically, please refer to Figure 2, the bracket 100 includes a connecting plate 110 and at least two support rings 120. All the support rings 120 are arranged side by side and spaced apart along a first direction, and both sides of all the support rings 120 along a second direction are fixedly connected by a connecting plate 110 respectively, so that all the support rings 120 jointly form a hollow cavity 101. The first direction is the axial direction of the bracket 100, and the second direction is the length direction of the bracket 100.

[0046] It should be noted that the first direction is Figure 2 the X direction shown, that is, the axial direction of the bracket 100; the second direction is Figure 2 the Y direction shown, that is, the length direction of the bracket 100.

[0047] Here, all the support rings 120 are arranged side by side and spaced apart along Figure 2 the X direction shown. At least one side of all the support rings 120 along Figure 1 the Y direction shown is fixedly connected by the connecting plate 110. In this way, it can be ensured that all the support rings 120 are sleeved outside the charging module 20, and there is a spacing between every two adjacent support rings 120 in Figure 2 the X direction shown, which is beneficial to the heat dissipation and cooling of the charging module 20.

[0048] In the embodiment of the present application, all the support rings 120 are arranged side by side and spaced apart along the first direction, and all the support rings 120 are equally spaced, so that the spacing between any two adjacent support rings 120 is equal, which is beneficial to the uniform heat dissipation of the charging module 20. In other embodiments, all the support rings 120 can also be arranged in a non-uniform spacing.

[0049] In the embodiment of the present application, both sides of all the support rings 120 along the second direction are fixedly connected by a connecting plate 110 respectively, that is: one side of all the support rings 120 along the second direction is fixedly connected by a connecting plate 110, or both sides of all the support rings 120 along the second direction are fixedly connected by different connecting plates 110 respectively. All the support rings 120 and the connecting plate 110 can be a split structure. For example, the support ring 120 and the connecting plate 110 are fixed by welding, riveting or other means; all the support rings 120 and the connecting plate 110 can also be an integral structure. For example, the support ring 120 and the connecting plate 110 are integrally formed by injection molding, casting.

[0050] In the embodiment of the present application, in Figure 2 the X direction shown, the size of the connecting plate 110 is equal to the size of the bracket 100, and the connecting plate 110 is provided with heat dissipation grooves. A heat dissipation groove is correspondingly arranged at the spacing between any two adjacent support rings 120, so as to facilitate the heat dissipation of the charging module 20. Among them, the connecting plate 110 can be in the shape of an arc-shaped plate, a flat plate or other shapes.

[0052] It can be understood that the cooling channel 102 is configured as an annular structure surrounding the support ring 120 in the circumferential direction. The liquid cooling mechanism 200 inputs a cooling medium into the cooling channel 102. After the cooling medium exchanges heat with the charging module 20, it is output from the cooling channel 102 to the liquid cooling mechanism 200, so as to cool down the charging module 20 by heat exchange. In this way, the cooling medium can circulate between the liquid cooling mechanism 200 and the cooling channel 102 of the support 100, which is beneficial to the heat exchange and cooling of the charging module 20.

[0053] In the embodiment of the present application, one cooling channel 102 can be provided inside each support ring 120, or at least two cooling channels 102 can be provided. Among them, the support ring 120 can be in a hollow cylindrical shape, a hollow elliptical cylindrical shape or other shapes. Correspondingly, the cooling channel 102 can be in a circular ring shape, an elliptical ring shape or other shapes.

[0054] Please refer to Figure 2 、 Figure 5 and Figure 6 , the liquid cooling mechanism 200 includes a mounting frame 210, a driving assembly 220, a liquid inlet assembly 230 and a liquid discharge assembly 240. The mounting frame 210 is connected to one side of the support 100 along the third direction and forms an accommodating space with the support 100. The driving assembly 220, the liquid inlet assembly 230 and the liquid discharge assembly 240 are all arranged in the accommodating space. The third direction intersects with the first direction and the second direction pairwise and is not coplanar; the liquid inlet assembly 230 is communicated with the inlet ends of the cooling channels 102, the liquid discharge assembly 240 is communicated with the outlet ends of the cooling channels 102, and the driving assembly 220 is respectively connected to the liquid inlet assembly 230 and the liquid discharge assembly 240 and is used to provide power for the flow of the cooling medium.

[0055] It should be noted that the third direction is the Figure 2 Z direction shown, that is, the thickness direction of the support 100. Driven by the driving assembly 220, the cooling medium is input into the inlet ends of the cooling channels 102 by the liquid inlet assembly 230. After the cooling medium exchanges heat with the charging module 20, it is output from the outlet ends of the cooling channels 102 to the liquid discharge assembly 240.

[0056] Here, there is a receiving space between the mounting frame 210 and the support frame 100. The driving assembly 220, the liquid inlet assembly 230, and the liquid discharge assembly 240 are all arranged in the receiving space, which can make the overall structure of the liquid cooling mechanism 200 more compact and is conducive to improving the space utilization rate. The liquid inlet assembly 230 is communicated with the inlet ends of the respective cooling channels 102, and the liquid discharge assembly 240 is communicated with the outlet ends of the respective cooling channels 102, which can enable the cooling medium to circulate between the liquid cooling mechanism 200 and the cooling channels 102 of the support frame 100, facilitating the heat exchange and temperature reduction of the charging module 20.

[0057] In an embodiment of the present application, the driving assembly 220 is a component that is respectively connected to the liquid inlet assembly 230 and the liquid discharge assembly 240 and is used to provide power for the flow of the cooling medium. The driving assembly 220 can adopt various structural forms. For example, the driving assembly 220 is a driving component such as a motor or a lead screw.

[0058] In an embodiment of the present application, the liquid inlet assembly 230 is a component that is communicated with the inlet ends of the respective cooling channels 102, and the cooling medium is input into the inlet ends of the respective cooling channels 102 by the liquid inlet assembly 230. Among them, the number of the liquid inlet assemblies 230 is not limited to one.

[0059] In an embodiment of the present application, the liquid discharge assembly 240 is a component that is communicated with the outlet ends of the respective cooling channels 102, and the cooling medium is output from the outlet ends of the respective cooling channels 102 to the liquid discharge assembly 240. Among them, the number of the liquid discharge assemblies 240 is not limited to one.

[0060] Further, please refer to Figure 5 and Figure 6 , the liquid inlet assembly 230 includes a first row pipe 231 and a liquid inlet pipe 232. The first row pipe 231 communicates with the driving assembly 220 and one end of the liquid inlet pipe 232. The other end of the liquid inlet pipe 232 is provided with at least two liquid inlet holes 232a at intervals in the first direction. The other end of the liquid inlet pipe 232 penetrates through each support ring 120 in the first direction, and each liquid inlet hole 232a is communicated with the inlet end of the cooling channel 102 of the corresponding support ring 120. The liquid discharge assembly 240 includes a second row pipe 241 and a liquid discharge pipe 242. The liquid discharge pipe 242 is spaced from the liquid inlet pipe 232 in the third direction. The second row pipe 241 communicates with the driving assembly 220 and one end of the liquid discharge pipe 242. The other end of the liquid discharge pipe 242 is provided with at least two liquid discharge holes 242a at intervals in the first direction. The other end of the liquid discharge pipe 242 penetrates through each support ring 120 in the first direction, and each liquid discharge hole 242a is communicated with the outlet end of the cooling channel 102 of the corresponding support ring 120.

[0061] It can be understood that the liquid discharge pipe 242 and the liquid inlet pipe 232 are spaced from each other in the third direction, that is, the liquid discharge pipe 242 and the liquid inlet pipe 232 are in Figure 5 and Figure 6Are spaced apart in the Z direction as shown.

[0062] Here, driven by the driving component 220, the cooling medium can enter the liquid inlet pipe 232 from the first row of pipes 231, and flow into the cooling channel 102 through the liquid inlet holes 232a of the liquid inlet pipe 232; after the cooling medium in the cooling channel 102 exchanges heat with the charging module 20, it is output to the liquid discharge pipe 242 through the liquid discharge holes 242a of the liquid discharge pipe 242, and flows from the liquid discharge pipe 242 to the second row of pipes 241 and the driving component 220. In this way, the cooling medium can be circulated between the liquid cooling mechanism 200 and the cooling channel 102 of the bracket 100, which is beneficial to the heat exchange and cooling of the charging module 20.

Since all the support rings 120 are Figure 1 Spaced apart side by side in the X direction as shown, the other end of the liquid inlet pipe 232 is along Figure 1 The X direction shown penetrates through all the support rings 120, so that the other end of the liquid inlet pipe 232 penetrates through all the support rings 120, and the liquid inlet holes 232a on the liquid inlet pipe 232 communicate with the inlet ends of the cooling channels 102 of the corresponding support rings 120.

[0079] It can be understood that under the drive of the driving member 222, the first transmission assembly 320 drives the first air supply blade 330 to rotate to generate an air flow for assisting in cooling the cooling channel 102. In this way, the heat of the cooling channel 102 can be dissipated by the air cooling mechanism 300, thereby improving the ability to cool the cooling medium.

[0080] In the embodiment of the present application, the fixing plate 310 is a member fixed in the accommodating space and can provide an installation space for the installation of other components.

[0084] It should be noted that, driven by the driving member 222, the driving bevel gear 323 rotates. Under the meshing transmission between the driving bevel gear 323 and the driven bevel gear 324, the transmission shaft 321 is driven to rotate. Under the meshing transmission between the connecting bevel gear 325 and the driving bevel gear 326, the connecting shaft 322 is driven to rotate, thereby driving the first air supply blade 330 to rotate to generate an air flow for cooling the auxiliary cooling channel 102. In this way, the first air supply blade 330 can be smoothly driven to rotate through the first transmission assembly 320, and the heat of the cooling channel 102 can be dissipated by the air cooling mechanism 300, so as to improve the ability to cool the cooling medium.

[0085] In an embodiment of the present application, the first air supply blade 330 and the driving bevel gear 326 are respectively provided at both ends of the connecting shaft 322. The connecting shaft 322, the first air supply blade 330 and the driving bevel gear 326 can be of a split structure. For example, the connecting shaft 322, the first air supply blade 330 and the driving bevel gear 326 are fixed by welding, riveting and other methods; or, the connecting shaft 322, the first air supply blade 330 and the driving bevel gear 326 can also be of an integral structure. For example, the connecting shaft 322, the first air supply blade 330 and the driving bevel gear 326 are integrally formed by injection molding, casting and other methods.

[0086] In an embodiment of the present application, driven bevel gears 324 and connecting bevel gears 325 are respectively provided at both ends of the transmission shaft 321.

[0088] Please refer to Figure 6 and Figure 7 , the air cooling mechanism 300 further includes at least two rotating shafts 340, a second transmission assembly 350, and second air supply blades 360. At least one second air supply blade 360 is respectively provided at one end of each rotating shaft 340, and the other end of each rotating shaft 340 is rotatably arranged on the fixing plate 310; all the rotating shafts 340 are spaced apart and symmetrically distributed on both sides of the connecting shaft 322 along the second direction, and each rotating shaft 340 is drivingly connected to the connecting shaft 322 through a second transmission assembly 350.

[0089] It can be understood that when the connecting shaft 322 rotates, the second transmission assembly 350 drives each rotating shaft 340 to rotate, thereby driving the second air supply blades 360 on each rotating shaft 340 to rotate, so as to generate an air flow for assisting in cooling the cooling channel 102. In this way, the second transmission assembly 350 can smoothly drive the second air supply blades 360 to rotate, and the air cooling mechanism 300 can blow away the heat of the cooling channel 102, thereby improving the ability to cool the cooling medium.

[0090] In an embodiment of the present application, at least one second air supply blade 360 is respectively provided at one end of each rotating shaft 340. The rotating shaft 340 and the second air supply blade 360 may be of a split structure.

For example, a fixing hole is formed on the fixed plate 310, and the rotating shaft 340 is inserted into the fixing hole and can rotate relative to the fixing hole.

[0092] In an embodiment of the present application, all the rotating shafts 340 are spaced apart and symmetrically distributed on both sides of the connecting shaft 322 along the second direction, that is, the rotating shafts 340 are symmetrically distributed on both sides of the connecting shaft 322 along the second direction, and the number of rotating shafts 340 on each side of the connecting shaft 322 along the second direction is not limited to one.

[0093] Specifically, please refer to Figure 7 , the second transmission assembly 350 includes a first synchronous pulley 351, a second synchronous pulley 352 and a synchronous belt 353. The first synchronous pulley 351 is provided on the connecting shaft 322, and the second synchronous pulley 352 is provided on each rotating shaft 340. The synchronous belt 353 is sleeved outside the first synchronous pulley 351 and the second synchronous pulley 352; under the drive of the driving member 222, the connecting shaft 322 rotates, which can drive the first synchronous pulley 351 and the second synchronous pulley 352 to rotate synchronously, and each rotating shaft 340 and the second air supply blade 360 rotate to generate an air flow for assisting in cooling the cooling channel 102.

[0094] It can be understood that under the drive of the driving member 222, the connecting shaft 322 rotates, which can drive the first synchronous pulley 351 and the second synchronous pulley 352 to rotate synchronously, and at the same time drive each rotating shaft 340 to rotate, so as to drive the second air supply blades 360 on each rotating shaft 340 to rotate to generate an air flow for assisting in cooling the cooling channel 102. In this way, the second air supply blade 360 can be smoothly driven to rotate through the second transmission assembly 350, and the heat of the cooling channel 102 can be dissipated by the air cooling mechanism 300, thereby improving the ability to cool the cooling medium.

[0095] In an embodiment of the present application, the first synchronous pulley 351 is provided on the connecting shaft 322. The connecting shaft 322 and the first synchronous pulley 351 can be of a split structure. For example, the connecting shaft 322 and the first synchronous pulley 351 are fixed by welding, riveting and other methods; or, the connecting shaft 322 and the first synchronous pulley 351 can also be of an integral structure. For example, the connecting shaft 322 and the first synchronous pulley 351 are integrally formed by injection molding, casting and other methods.

[0096] In an embodiment of the present application, the second synchronous pulley 352 is provided on each rotating shaft 340.

[0097] More specifically, please refer to Figure 6 , the air-cooling mechanism 300 further includes a deflector 370. The first row of pipes 231 and the second row of pipes 241 are spaced apart in the third direction. The deflector 370 is provided on the side of the second air supply blade 360 away from the fixing plate 310. The deflector 370 is located between the first row of pipes 231 and the second row of pipes 241 and is used for guiding the flow.

[0098] It can be understood that, driven by the driving member 222, the driving bevel gear 323 rotates. Under the meshing transmission of the driving bevel gear 323 and the driven bevel gear 324, the transmission shaft 321 is driven to rotate. Under the meshing transmission of the connecting bevel gear 325 and the driving bevel gear 326, the connecting shaft 322 is driven to rotate, thereby driving the first air supply blade 330 to rotate. At the same time, when the connecting shaft 322 rotates, it can drive the first synchronous pulley 351 and the second synchronous pulley 352 to rotate synchronously, and at the same time drive each rotating shaft 340 to rotate, thereby driving the second air supply blades 360 on each rotating shaft 340 to rotate. In this way, under the guidance of the deflector 370, the air flow rate around the first row of pipes 231 and the second row of pipes 241 can be increased, so as to blow away the diffused heat, thereby enhancing the ability to cool the cooling medium.

[0099] In the embodiment of the present application, the deflector 370 is provided on the side of the second air supply blade 360 away from the fixing plate 310. The deflector 370 has a first side and a second side that are arranged opposite to each other along the Figure 6 Z direction shown. The first side faces the first row of pipes 231 and there is a first guiding gap with the first row of pipes 231. The second side faces the second row of pipes 241 and there is a second guiding gap with the second row of pipes 241. Under the guidance of the deflector 370, the air flow can be guided to the first guiding gap and the second guiding gap to quickly dissipate heat and cool down the first row of pipes 231 and the second row of pipes 241.

Optionally, the first guiding portion 371 and the second guiding portion 372 can be in the shape of a zigzag plate or a straight plate structure.
