[0002] With the rapid development of the electric vehicle industry, charging piles, as an important supporting facility for electric vehicles, directly affect the charging speed and user experience. Charging piles generate a significant amount of heat during operation; if this heat is not dissipated in time, it will not only reduce the efficiency of the charging pile but may also pose safety hazards. Traditional charging pile cooling methods mainly employ air cooling, using fans to blow heat off the surface of the charging pile. However, this method suffers from low cooling efficiency, high noise levels, and high maintenance costs, failing to meet the cooling requirements of current high-power charging piles.

[0039] Please refer to Figures 1 to 6 In one embodiment, the heat dissipation device 10 of the charging pile is used to dissipate heat for 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 on the outside of 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 channel 102 for the flow of cooling medium. The liquid cooling mechanism 200 is connected to the bracket 100 and communicates with the cooling channel 102. The air cooling mechanism 300 is connected to the liquid cooling mechanism 200. The cooling medium can flow between the liquid cooling mechanism 200 and the cooling channel 102. The air cooling mechanism 300 is used to assist the cooling channel 102 in cooling down.

[0040] It should be noted that the charging module 20 is one of the core components of the charging pile. It is mainly used to convert the input AC or DC power into DC power suitable for charging electric vehicle batteries, and can precisely control the charging current and voltage. During the operation of the charging pile, the charging module 20 will generate a lot of heat due to energy conversion and current transmission during the charging process. The flow of the cooling medium between the liquid cooling mechanism 200 and the cooling channel 102 of the bracket 100 enables the cooling medium to exchange heat with the liquid cooling mechanism 200 and cool down. At the same time, the air cooling mechanism 300 can assist the cooling channel 102 in rapid air cooling.

[0041] The heat dissipation device 10 of the aforementioned charging pile, since the bracket 100 is sleeved outside the charging module 20, allows the bracket 100 to continuously absorb the heat emitted by 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, thereby cooling the charging module 20. At the same time, the air cooling mechanism 300 can blow out cooling airflow to the bracket 100 to assist the cooling channel 102 in rapid air cooling, thereby achieving rapid and efficient cooling and heat dissipation of the charging module 20, keeping the operating temperature of the charging module 20 within the normal range, which is conducive to the stable operation of the charging module 20.

[0042] In the embodiments of this application, the bracket 100 is a component sleeved outside the charging module 20. The bracket 100 has a hollow cavity 101, which 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 cooling medium, which can be in the shape of a circular ring, an elliptical ring, or other shapes.

[0043] In the embodiments of this application, the liquid cooling mechanism 200 is a component for supplying cooling medium to the cooling channel 102 of the support 100 and receiving 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 drive pump and a controller. The drive 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 embodiments of this application, the air-cooling mechanism 300 is a component used to blow cooling airflow onto the support 100 to assist in cooling the cooling channel 102. 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 fan generates cooling airflow, and the air duct guides the cooling airflow to the location where heat dissipation is required.

[0045] For details, please refer to Figure 2The bracket 100 includes a connecting plate 110 and at least two support rings 120. All support rings 120 are arranged side by side at intervals along a first direction, and all support rings 120 are fixedly connected on both sides along a second direction by a connecting plate 110, so that all support rings 120 together 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 is the axial direction of the bracket 100; the second direction is... Figure 2 The Y direction shown is the length direction of the bracket 100.

[0047] Here, all support rings 120 along Figure 2 As shown, the support rings are arranged side-by-side at intervals along the X direction, with all support rings 120 along... Figure 1 At least one side in the Y direction is fixedly connected by a connecting plate 110, so that all the support rings 120 are sleeved on the outside of the charging module 20, and each pair of adjacent support rings 120 are in... Figure 2 The spacing in the X direction is beneficial for heat dissipation and cooling of the charging module 20.

[0048] In the embodiments of this application, all support rings 120 are arranged side-by-side at intervals along the first direction, and all support rings 120 are equally spaced, so that the distance between any two adjacent support rings 120 is equal, which is beneficial for uniform heat dissipation of the charging module 20. In other embodiments, all support rings 120 may also be non-equally spaced.

[0049] In the embodiments of this application, all support rings 120 are fixedly connected to each other on both sides of the second direction by a connecting plate 110. That is, all support rings 120 are fixedly connected to each other on one side of the second direction by a connecting plate 110, or all support rings 120 are fixedly connected to each other on both sides of the second direction by different connecting plates 110. All support rings 120 and connecting plates 110 can be separate structures, for example, the support rings 120 and connecting plates 110 can be fixed by welding, riveting or other methods; all support rings 120 and connecting plates 110 can also be integral structures, for example, the support rings 120 and connecting plates 110 can be integrally formed by injection molding or casting.

[0050] In the embodiments of this application, in Figure 2 In 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 provided at the distance between any two adjacent support rings 120 to facilitate heat dissipation of the charging module 20. The connecting plate 110 can be in the form of an arc plate, a flat plate, or other shapes.

[0051] For more specific details, please refer to Figures 3 to 4 Each support ring 120 has at least one cooling channel 102 inside, and the cooling channel 102 is configured as a ring structure that surrounds the support ring 120 in the circumferential direction.

[0052] Understandably, the cooling channel 102 is constructed as a ring structure surrounding the support ring 120. The liquid cooling mechanism 200 inputs cooling medium into the cooling channel 102. After heat exchange with the charging module 20, the cooling medium is output from the cooling channel 102 back to the liquid cooling mechanism 200, thereby cooling the charging module 20. 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 for the heat exchange and cooling of the charging module 20.

[0053] In the embodiments of this application, each support ring 120 may have one cooling channel 102 inside, or at least two cooling channels 102 may be provided. The support ring 120 may be hollow cylindrical, hollow elliptical cylindrical or other shapes, and correspondingly, the cooling channel 102 may be annular, elliptical annular 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 drive assembly 220, a liquid inlet assembly 230, and a liquid outlet assembly 240. The mounting frame 210 is connected to one side of the support 100 along a third direction and forms an accommodating space with the support 100. The drive assembly 220, the liquid inlet assembly 230, and the liquid outlet assembly 240 are all located within the accommodating space. The third direction intersects with the first direction and the second direction in pairs but are not coplanar. The liquid inlet assembly 230 is connected to the inlet end of each cooling channel 102, and the liquid outlet assembly 240 is connected to the outlet end of each cooling channel 102. The drive assembly 220 is connected to the liquid inlet assembly 230 and the liquid outlet assembly 240 respectively and is used to provide power for the flow of the cooling medium.

[0055] It should be noted that the third party is... Figure 2 The Z direction shown is the thickness direction of the support 100. Driven by the drive assembly 220, the cooling medium is input into the inlet end of each cooling channel 102 through the liquid inlet assembly 230. After heat exchange with the charging module 20, the cooling medium is output from the outlet end of each cooling channel 102 to the drain assembly 240.

[0056] Here, there is an accommodating space between the mounting bracket 210 and the support 100. The drive assembly 220, the liquid inlet assembly 230, and the liquid outlet assembly 240 are all located within the accommodating space, which makes the overall structure of the liquid cooling mechanism 200 more compact and helps to improve space utilization. The liquid inlet assembly 230 is connected to the inlet end of each cooling channel 102, and the liquid outlet assembly 240 is connected to the outlet end of each cooling channel 102, which allows the cooling medium to circulate between the cooling channels 102 of the liquid cooling mechanism 200 and the support 100, which is beneficial for the heat exchange and cooling of the charging module 20.

[0057] In the embodiments of this application, the drive assembly 220 is a component connected to the liquid inlet assembly 230 and the liquid outlet assembly 240 respectively, and is used to provide power for the flow of the cooling medium. The drive assembly 220 can take various structural forms, such as a drive component of the type of motor or lead screw.

[0058] In the embodiments of this application, the liquid inlet assembly 230 is a component that communicates with the inlet end of each cooling channel 102, and the cooling medium is input into the inlet end of each cooling channel 102 through the liquid inlet assembly 230. The number of liquid inlet assemblies 230 is not limited to one.

[0059] In the embodiments of this application, the drain assembly 240 is a component connected to the outlet end of each cooling channel 102, and the cooling medium is output from the outlet end of each cooling channel 102 to the drain assembly 240. The number of drain 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 of pipes 231 and a liquid inlet pipe 232. The first row of pipes 231 connects to the drive 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 spaced apart along a first direction. The other end of the liquid inlet pipe 232 extends through each support ring 120 along the first direction, and each liquid inlet hole 232a is connected to the inlet end of the cooling channel 102 of the corresponding support ring 120. The liquid drain assembly 240 includes a second... The drain pipe 241 and the drain pipe 242 are distributed at intervals in the third direction. The second drain pipe 241 connects the drive assembly 220 and one end of the drain pipe 242. The other end of the drain pipe 242 is provided with at least two drain holes 242a at intervals along the first direction. The other end of the drain pipe 242 passes through each support ring 120 along the first direction, and each drain hole 242a is connected to the outlet end of the cooling channel 102 of the corresponding support ring 120.

[0061] It is understandable that the drain pipe 242 and the inlet pipe 232 are distributed at intervals in the third direction, that is, the drain pipe 242 and the inlet pipe 232 are... Figure 5 and Figure 6The distribution is spaced out along the Z direction as shown.

[0062] Here, driven by the drive assembly 220, the cooling medium enters the inlet pipe 232 from the first pipe 231 and flows into the cooling channel 102 through the inlet hole 232a of the inlet pipe 232. After exchanging heat with the charging module 20, the cooling medium in the cooling channel 102 is output to the drain pipe 242 through the drain hole 242a, and then flows from the drain pipe 242 to the second pipe 241 and the drive assembly 220. In this way, the cooling medium can circulate between the cooling channel 102 of the liquid cooling mechanism 200 and the support 100, which is beneficial to the heat exchange and cooling of the charging module 20.

[0063] In the embodiments of this application, one end of the inlet pipe 232 is connected to the first row of pipes 231, and the other end of the inlet pipe 232 extends through each support ring 120 along the first direction. Since all support rings 120 are along... Figure 1 As shown, the inlet pipes 232 are arranged side by side at intervals along the X direction, with the other end of the inlet pipe along... Figure 1 The X-direction shown penetrates through all support rings 120, so that the other end of the liquid inlet pipe 232 passes through all support rings 120, and the liquid inlet hole 232a on the liquid inlet pipe 232 is connected to the inlet end of the cooling channel 102 of the corresponding support ring 120. The number of liquid inlet holes 232a corresponds to the number of support rings 120, and the shape of the liquid inlet holes 232a can be round, square, or other shapes.

[0064] In the embodiments of this application, one end of the drain pipe 242 is connected to the second drain pipe 241, and the other end of the drain pipe 242 extends through each support ring 120 along the first direction. Since all support rings 120 are along... Figure 1 As shown, the drain pipes are arranged side-by-side at intervals along the X direction, and the other end of the drain pipe 242 is along... Figure 1 The X-direction extends through all support rings 120, so that the other end of the drain pipe 242 passes through all support rings 120, and the drain hole 242a on the drain pipe 242 is connected to the outlet end of the cooling channel 102 of the corresponding support ring 120. The number of drain holes 242a corresponds to the number of support rings 120, and the shape of the drain holes 242a can be round, square, or other shapes.

[0065] Furthermore, please refer to Figure 5 and Figure 6The drive assembly 220 includes a power box 221, a drive component 222, a water suction blade 223, a flow pipe 224, and a return pipe 225. The power box 221 and the first row of pipes 231 are connected through the flow pipe 224, and the power box 221 and the second row of pipes 241 are connected through the return pipe 225. The water suction blade 223 is located inside the power box 221, and the drive component 222 is connected to the water suction blade 223 and is used to drive the water suction blade 223 to rotate.

[0066] It should be noted that, driven by the drive component 222, the water suction blade 223 rotates within the power box 221. The rotation of the water suction blade 223 generates pressure, allowing the cooling medium to flow sequentially through the flow pipe 224, the first row pipe 231, and the liquid inlet pipe 232 before entering the cooling channel 102. The cooling medium within the cooling channel 102 then flows sequentially through the drain pipe 242, the second row pipe 241, and the return pipe 225 to be discharged, thus circulating the cooling medium between the liquid cooling mechanism 200 and the cooling channel 102 of the support 100. This circulation of the cooling medium between the liquid cooling mechanism 200 and the cooling channel 102 of the support 100 facilitates heat exchange and cooling of the charging module 20, and allows for resource reuse.

The fixing part is located outside the power box 221, and the power output shaft passes through the power box 221 and is fixedly connected to the water suction blade 223. The rotation of the power output shaft can drive the water suction blade 223 to rotate. The number of water suction blades 223 is not limited to one.

[0068] In the embodiments of this application, one end of the flow tube 224 is fixedly connected to the power box 221, and the other end of the flow tube 224 is fixedly connected to the first row of pipes 231. Optionally, one end of the flow tube 224 is fixedly connected to the power box 221 by welding, riveting, or other methods, and the other end of the flow tube 224 is fixedly connected to the first row of pipes 231 by welding, riveting, or other methods.

Figure 6 As shown, the two sides in the Y direction. In this way, the cooling medium can be diverted from one first distribution box 231a to each of the first heat exchange tubes 231b, and then converge to another first distribution box 231a to flow out, which can increase the delivery area of ​​the cooling medium and help improve the cooling efficiency.

[0072] In the embodiments of this application, each first heat exchange tube 231b along Figure 6 The first heat exchange tubes 231b are arranged side-by-side at intervals along the Y direction, with each tube equally spaced to ensure that the distance between any two adjacent tubes is equal, which facilitates uniform heat dissipation of the charging module 20. In other embodiments, all the first heat exchange tubes 231b may also be arranged with non-equal spacing.

[0073] In the embodiments of this application, the first distribution box 231a is fixedly connected to the first heat exchange tube 231b, for example, by welding, riveting, or other means. The first distribution box 231a has an inner cavity that communicates with the first heat exchange tube 231b. The first distribution box 231a can be rectangular, cylindrical, or other shapes.

[0074] For a specific embodiment, please refer to Figure 6 The second row of pipes 241 includes two second distribution boxes 241a and at least two second heat exchange tubes 241b.

[0075] It is understandable that each of the second heat exchange tubes 241b along Figure 6 As shown, the two second distribution boxes 241a are arranged side-by-side and spaced apart along the Y direction, respectively located along the second heat exchange tubes 241b. Figure 6As shown, the two sides in the Y direction. In this way, the cooling medium can be diverted from one second distribution box 241a to each of the second heat exchange tubes 241b, and then converge to another second distribution box 241a to flow out, which can increase the delivery area of ​​the cooling medium and help improve the cooling efficiency.

[0076] In the embodiments of this application, each second heat exchange tube 241b along Figure 6 The second heat exchange tubes 241b are arranged side-by-side at intervals along the Y direction, with each tube equally spaced to ensure that the distance between any two adjacent tubes is equal, which facilitates uniform heat dissipation of the charging module 20.

The fixed plate 310 is fixed in the accommodating space, and the first air delivery blade 330 is fixed to one end of the first transmission assembly 320. The other end of the first transmission assembly 320 passes through the fixed plate 310 and is connected to the drive member 222. Under the drive of the drive member 222, the first transmission assembly 320 drives the first air delivery blade 330 to rotate, so as to generate an airflow to assist the cooling channel 102 in cooling down.

[0079] Understandably, driven by the drive component 222, the first transmission assembly 320 drives the first air delivery blade 330 to rotate, thereby generating airflow to assist in cooling the cooling channel 102. In this way, the air-cooling mechanism 300 can dissipate the heat of the cooling channel 102, thereby improving the cooling capacity of the cooling medium.

[0080] In the embodiments of this application, the fixing plate 310 is a component fixed within the accommodating space, providing installation space for the installation of other components. The fixing plate 310 may be a circular plate, a rectangular plate, or other shaped structures.

[0081] In the embodiments of this application, the first transmission assembly 320 is a component that drives the drive member 222 and the first air delivery blade 330. The first transmission assembly 320 can adopt various structures. For example, the first transmission assembly 320 is a transmission assembly including components such as a lead screw, a slider, and gears.

[0082] In the embodiments of this application, the first air delivery blade 330 is a component for generating airflow to cool the auxiliary cooling channel 102, and the first air delivery blade 330 is connected to the first transmission assembly 320. The number of first air delivery blades 330 is not limited to one.

[0083] For details, please refer to Figure 6 and Figure 8 The first transmission assembly 320 includes a transmission shaft 321, a connecting shaft 322, a driving bevel gear 323, a driven bevel gear 324, a connecting bevel gear 325, and a drive bevel gear 326. The first air delivery blade 330 is fixed to one end of the connecting shaft 322, and the other end of the connecting shaft 322 is provided with a drive bevel gear 326. The two ends of the transmission shaft 321 are respectively provided with a driven bevel gear 324 and a connecting bevel gear 325. The connecting bevel gear 325 meshes with the drive bevel gear 326, the driven bevel gear 324 meshes with the driving bevel gear 323, and the driving bevel gear 323 is connected to the drive member 222.

[0084] It should be noted that, driven by the drive component 222, the active bevel gear 323 rotates. The active bevel gear 323 meshes with the driven bevel gear 324, driving the transmission shaft 321 to rotate. The meshing of the connecting bevel gear 325 and the drive bevel gear 326 drives the connecting shaft 322 to rotate, thereby driving the first air delivery blade 330 to rotate, generating airflow to assist in cooling the cooling channel 102. Thus, the first transmission component 320 smoothly drives the first air delivery blade 330 to rotate, and the air-cooling mechanism 300 dissipates the heat from the cooling channel 102, thereby improving the cooling capacity of the cooling medium.

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

[0086] In the embodiments of this application, the two ends of the drive shaft 321 are respectively provided with a driven bevel gear 324 and a connecting bevel gear 325. The drive shaft 321, the driven bevel gear 324 and the connecting bevel gear 325 can be a split structure. For example, the drive shaft 321, the driven bevel gear 324 and the connecting bevel gear 325 can be fixed by welding, riveting or other methods; or, the drive shaft 321, the driven bevel gear 324 and the connecting bevel gear 325 can also be an integral structure. For example, the drive shaft 321, the driven bevel gear 324 and the connecting bevel gear 325 can be integrally formed by injection molding, casting or other methods.

[0087] In the embodiments of this application, the active bevel gear 323 is connected to the drive member 222. The active bevel gear 323 and the drive member 222 are separate structures. For example, the active bevel gear 323 and the power output shaft of the drive member 222 are fixed by welding, riveting or other methods.

[0088] Please refer to Figure 6 and Figure 7 The air-cooling mechanism 300 also includes at least two rotating shafts 340, a second transmission assembly 350, and a second air delivery blade 360. Each rotating shaft 340 has at least one second air delivery blade 360 ​​at one end, and the other end of each rotating shaft 340 is rotatably mounted on the fixed plate 310. All rotating shafts 340 are spaced apart and symmetrically distributed on both sides of the connecting shaft 322 along the second direction. Each rotating shaft 340 is connected to the connecting shaft 322 through a second transmission assembly 350.

[0089] Understandably, when the connecting shaft 322 rotates, the second transmission assembly 350 drives each rotating shaft 340 to rotate, thereby causing the second air delivery blades 360 on each rotating shaft 340 to rotate, generating airflow to assist in cooling the cooling channel 102. Thus, the second transmission assembly 350 can smoothly drive the second air delivery blades 360 to rotate, and the air-cooling mechanism 300 can dissipate the heat from the cooling channel 102, thereby improving the cooling capacity of the cooling medium.

[0090] In the embodiments of this application, each rotating shaft 340 is provided with at least one second air delivery blade 360 ​​at one end. The rotating shaft 340 and the second air delivery blade 360 ​​can be a separate structure, for example, the rotating shaft 340 and the second air delivery blade 360 ​​can be fixed by welding, riveting or other methods; or, the rotating shaft 340 and the second air delivery blade 360 ​​can also be an integral structure, for example, the rotating shaft 340 and the second air delivery blade 360 ​​can be integrally formed by injection molding, casting or other methods.

[0091] In the embodiments of this application, the other end of each rotating shaft 340 is rotatably disposed on the fixing plate 310. The rotating shaft 340 and the fixing plate 310 can be rotatably connected by various structural forms. For example, a fixing hole is opened on the fixing plate 310, and the rotating shaft 340 is inserted into the fixing hole and can rotate relative to the fixing hole.

[0092] In the embodiments of this application, all rotating shafts 340 are spaced apart and symmetrically distributed on both sides of the connecting shaft 322 along the second direction. That is, 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] For details, 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 on 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. Each rotating shaft 340 and the second air delivery blade 360 ​​rotate to generate airflow for assisting the cooling channel 102 in cooling down.

[0094] Understandably, driven by the drive component 222, the connecting shaft 322 rotates, which in turn drives the first synchronous pulley 351 and the second synchronous pulley 352 to rotate synchronously. Simultaneously, this drives each rotating shaft 340 to rotate, thereby causing the second air-blowing blades 360 on each rotating shaft 340 to rotate, generating airflow to assist in cooling the cooling channel 102. Thus, the second transmission assembly 350 smoothly drives the second air-blowing blades 360 to rotate, and the air-cooling mechanism 300 dissipates the heat from the cooling channel 102, thereby enhancing the cooling capacity of the cooling medium.

[0095] In the embodiments of this application, a first synchronous wheel 351 is provided on the connecting shaft 322. The connecting shaft 322 and the first synchronous wheel 351 can be a separate structure. For example, the connecting shaft 322 and the first synchronous wheel 351 can be fixed by welding, riveting or other methods. Alternatively, the connecting shaft 322 and the first synchronous wheel 351 can also be an integral structure. For example, the connecting shaft 322 and the first synchronous wheel 351 can be integrally formed by injection molding, casting or other methods.

[0096] In the embodiments of this application, each rotating shaft 340 is provided with a second synchronous wheel 352. The rotating shaft 340 and the second synchronous wheel 352 can be a separate structure, for example, the rotating shaft 340 and the second synchronous wheel 352 can be fixed by welding, riveting or other methods; or, the rotating shaft 340 and the second synchronous wheel 352 can also be an integral structure, for example, the rotating shaft 340 and the second synchronous wheel 352 can be integrally formed by injection molding, casting or other methods.

[0097] For more specific details, please refer to Figure 6 The air-cooling mechanism 300 also includes a guide plate 370. The first row of pipes 231 and the second row of pipes 241 are distributed at intervals in the third direction. The guide plate 370 is located on the side of the second air delivery blade 360 ​​away from the fixed plate 310. The guide plate 370 is located between the first row of pipes 231 and the second row of pipes 241 and is used for air guidance.

[0098] Understandably, driven by the drive component 222, the active bevel gear 323 rotates. The meshing of the active bevel gear 323 and the driven bevel gear 324 drives the drive shaft 321 to rotate. The meshing of the connecting bevel gear 325 and the drive bevel gear 326 drives the connecting shaft 322 to rotate, thereby driving the first air delivery blade 330 to rotate. Simultaneously, the rotation of the connecting shaft 322 drives the first synchronous pulley 351 and the second synchronous pulley 352 to rotate synchronously, which in turn drives each rotating shaft 340 to rotate, thereby driving the second air delivery blades 360 on each rotating shaft 340 to rotate. Thus, guided by the guide plate 370, the airflow rate around the first row of pipes 231 and the second row of pipes 241 can be increased, thereby dissipating the diffused heat and improving the cooling capacity of the cooling medium.

[0099] In the embodiments of this application, the guide vane 370 is disposed on the side of the second air delivery blade 360 ​​away from the fixed plate 310, and the guide vane 370 has a flow path along... Figure 6 The first and second sides are arranged opposite to each other in the Z direction. The first side faces the first pipe 231 and has a first flow guide gap with the first pipe 231. The second side faces the second pipe 241 and has a second flow guide gap with the second pipe 241. Under the guidance of the flow guide plate 370, the airflow can be guided to the first flow guide gap and the second flow guide gap to quickly dissipate heat and cool down the first pipe 231 and the second pipe 241.

[0100] For example, the guide plate 370 includes a first guide portion 371 and a second guide portion 372. One end of the first guide portion 371 and one end of the second guide portion 372 are fixedly connected, and the other ends of the first guide portion 371 and the second guide portion 372 are... Figure 6 As shown, the components are spaced apart along the Z direction. The first side is the side of the first guide section 371 facing the first pipe 231, and the second side is the side of the second guide section 372 facing the second pipe 241. Optionally, the first guide section 371 and the second guide section 372 can be in the form of a curved plate or a straight plate structure.

[0101] Please refer to Figure 1 In one embodiment, the charging pile includes a charging module 20 and a heat dissipation device 10 for the charging pile, wherein the heat dissipation device 10 is used to dissipate heat from the charging module 20.

[0102] It should be noted that the charging pile also includes a cable 30 and a plug 40. The two ends of the cable 30 are connected to the charging module 20 and the plug 40, respectively. When the plug 40 is plugged into the electric vehicle, the charging pile can charge the electric vehicle.

[0103] In the aforementioned charging pile, the heat dissipation device 10 of the charging pile has a bracket 100 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 out cooling airflow to the bracket 100 to assist the cooling channel 102 in rapid air cooling, thereby achieving rapid and efficient cooling and heat dissipation of the charging module 20, keeping the operating temperature of the charging module 20 within the normal range, which is conducive to the stable operation of the charging module 20.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
