[0002] A charging pile, also known as an electric vehicle charging station or an electric vehicle power supply device, is a device that provides electrical energy for electric vehicles, enabling electric vehicles to store sufficient electricity to support their operation. When the charging pile charges the vehicle, a large amount of heat is generated. If the heat cannot be dissipated in time, it will affect the normal use of the charging pile.

By setting heat dissipation openings and corresponding air delivery components on the charging pile, ventilation and heat dissipation are carried out inside the charging pile. However, since the charging pile is mostly used outdoors, ventilating and dissipating heat through the heat dissipation openings allows external dust and moisture to easily enter the interior of the charging pile, thereby causing the electronic components inside the charging pile to be contaminated and corroded, affecting the service life of the charging pile.

[0013] The present invention also discloses a heat dissipation method, and the specific steps are as follows: Drive the air inside the drive cabinet to circulate and be conveyed along the inner heat exchange air duct through the inner air supply assembly, and at the same time drive the outside air to circulate and be conveyed along the outer heat exchange air duct through the outer air supply assembly. At this time, the air in the outer heat exchange air duct cools the air in the inner heat exchange air duct through the heat exchange assembly, thereby dissipating heat inside the cabinet; When the external temperature is high and heat exchange by air alone is insufficient to dissipate heat inside the cabinet, the air inlet end and the air outlet end of the internal heat exchange air duct are sealed off by the sealing partition assembly, and at the same time, the air inlet end and the air outlet end of the external heat exchange air duct are sealed off. Then, through the connecting assembly, the air inlet end of the internal heat exchange air duct can be connected to the air inlet end of the external heat exchange air duct, and at the same time, the air outlet end of the internal heat exchange air duct is connected to the air outlet end of the external heat exchange air duct. At this time, the internal air supply assembly and the external air supply assembly can discharge the air inside the cabinet to the outside through the air outlet end of the internal heat exchange air duct and the air outlet end of the external heat exchange air duct, and at the same time, suck the external air into the cabinet under negative pressure through the air inlet end of the internal heat exchange air duct and the air inlet end of the external heat exchange air duct to directly ventilate and dissipate heat inside the cabinet.

[0014] The present invention has the following beneficial effects: 1. In the present invention, the internal air supply assembly drives the air inside the cabinet to circulate and be transported along the internal heat exchange air duct, and at the same time, the external air supply assembly drives the external air to circulate and be transported along the external heat exchange air duct. At this time, the air in the external heat exchange air duct cools the air in the internal heat exchange air duct through the heat exchange assembly, thereby dissipating heat inside the cabinet. Since the heat dissipation inside the cabinet is achieved through the cooperation of the internal and external air ducts and the heat exchange assembly, the whole cabinet is in a sealed state, so that it can prevent external dust and water vapor from entering the inside of the cabinet, polluting and corroding the electronic components inside the cabinet, and thus can improve the service life of the charging pile.

[0015] 2. In the present invention, when the external temperature is high and the indirect heat dissipation by air alone is insufficient to dissipate heat inside the cabinet, the internal and external air ducts are adjusted through the air duct adjustment mechanism to directly connect the cabinet to the outside. At the same time, through the cooperation of the internal air supply assembly and the external air supply assembly, the air inside the cabinet is discharged to the outside through the air outlet end of the internal heat exchange air duct and the air outlet end of the external heat exchange air duct, and the external air is sucked into the cabinet under negative pressure through the air inlet end of the internal heat exchange air duct and the air inlet end of the external heat exchange air duct to directly ventilate and dissipate heat inside the cabinet, thereby greatly improving the heat dissipation effect on the charging pile; and the situation of high external temperature generally only occurs in summer and when the weather is sunny. At this time, the external air is dry, and directly ventilating and dissipating heat inside the cabinet will not cause water vapor to enter the inside of the cabinet, so that the cabinet can always maintain a good waterproof effect. By setting dust-proof nets on the internal and external air inlet surfaces, dust can be prevented from entering the air ducts and the inside of the cabinet. At the same time, through occasional ventilation and heat dissipation, the waste gas generated during the operation of the electronic components inside the cabinet and the damp water vapor inside the cabinet can be discharged, thereby improving the service life of the electronic components inside the cabinet.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts fall within the scope of protection of the invention.

[0021] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0022] Embodiment 1 See also Figures 1-5 As shown, the present invention is a heat dissipation protection structure, comprising a cabinet 1 and a heat dissipation mechanism 2 fixedly mounted on the cabinet 1, the heat dissipation mechanism 2 comprising a heat dissipation frame 21, a cooling heat exchange component fixedly mounted inside the heat dissipation frame 21, a plurality of staggered internal heat exchange air ducts and external heat exchange air ducts are arranged inside the cooling heat exchange component, the air inlet end and the air outlet end of the internal heat exchange air duct are evenly connected to the inside of the cabinet 1, the air outlet end of the internal heat exchange air duct is equipped with an internal air supply component capable of driving the air inside the cabinet 1 to circulate and transport along the internal heat exchange air duct, the air inlet end and the air outlet end of the external heat exchange air duct are both connected to the outside of the cabinet 1, the air outlet end of the external heat exchange air duct is equipped with an external air supply component capable of driving the outside air to circulate and transport along the external heat exchange air duct, and the air can be heat exchanged through the cooling heat exchange component when circulating in the internal heat exchange air duct and the external heat exchange air duct; An air duct regulating mechanism 3 is also installed inside the cooling heat exchange component. The air duct regulating mechanism 3 includes two groups of sealed partition components and two groups of connecting components. The two groups of sealed partition components can respectively seal and separate the air inlet and air outlet of the inner heat exchange air duct and the air inlet and air outlet of the outer heat exchange air duct. The two groups of connecting components can connect the air inlet of the inner heat exchange air duct with the air inlet of the outer heat exchange air duct, and can also connect the air outlet of the inner heat exchange air duct with the air outlet of the outer heat exchange air duct, so that the inner air supply component and the outer air supply component can discharge the air inside the cabinet 1 to the outside through the air outlet of the inner heat exchange air duct and the air outlet of the outer heat exchange air duct, and at the same time, negative pressure outside air is sucked into the cabinet 1 through the air inlet of the inner heat exchange air duct and the air inlet of the outer heat exchange air duct; During heat dissipation, the internal air supply component drives the air inside the drive cabinet 1 to circulate and be transported along the internal heat exchange air duct, while the external air supply component drives the external air to circulate and be transported along the external heat exchange air duct. At this time, the air in the external heat exchange air duct exchanges heat and cools down the air in the internal heat exchange air duct through the heat exchange component, thereby dissipating heat inside the cabinet 1; when the external temperature is high and heat dissipation inside the cabinet 1 cannot be achieved only by air heat exchange, the air inlet end and the air outlet end of the internal heat exchange air duct are sealed off by the sealing partition component, and the air inlet end and the air outlet end of the external heat exchange air duct are sealed off. Then, through the connection component, the air inlet end of the internal heat exchange air duct can be connected to the air inlet end of the external heat exchange air duct, and the air outlet end of the internal heat exchange air duct can be connected to the air outlet end of the external heat exchange air duct. At this time, the internal air supply component and the external air supply component can discharge the internal air of the cabinet 1 to the outside through the air outlet end of the internal heat exchange air duct and the air outlet end of the external heat exchange air duct, and at the same time, suck the external air into the cabinet 1 under negative pressure through the air inlet end of the internal heat exchange air duct and the air inlet end of the external heat exchange air duct to directly ventilate and dissipate heat inside the cabinet 1; Among them, the cooperation of the internal and external air ducts and the heat exchange component is used to dissipate heat inside the cabinet 1, so that the cabinet 1 is in a sealed state during heat dissipation, thereby preventing external dust and water vapor from entering the inside of the cabinet 1 and polluting and corroding the electronic components inside the cabinet 1, and further improving the service life of the electronic components inside the cabinet 1; in the present invention, when the external temperature is high and indirect heat dissipation only by air heat exchange is not sufficient to dissipate heat inside the cabinet, the internal and external air ducts are adjusted by the air duct adjustment mechanism 3 to directly connect the cabinet 1 to the outside, and then the heat dissipation mechanism 2 is used to ventilate and dissipate heat inside the cabinet 1, thereby greatly improving the heat dissipation effect inside the cabinet 1; and the situation of high external temperature generally only occurs in summer and when the weather is sunny. At this time, the external air is dry, and direct ventilation and heat dissipation inside the cabinet 1 will not cause water vapor to enter the inside of the cabinet 1, so that the cabinet 1 can always maintain a good waterproof effect. At the same time, through occasional ventilation and heat dissipation, the waste gas generated during the operation of the electronic components inside the cabinet 1 and the humid water vapor inside the cabinet 1 can be discharged, which is beneficial to improving the service life of the electronic components inside the cabinet.

[0023] Embodiment 2 Please refer to Figures 2-5As shown in the figure, the difference between this embodiment and the above embodiment is that the cooling and heat dissipation component includes a plurality of heat exchange plates 28. Inner and outer heat exchange air ducts are respectively arranged on both sides of the heat exchange plate 28. The plurality of heat exchange plates 28 are tightly installed inside the heat dissipation frame 21 in sequence from top to bottom to form a staggered inner heat exchange air duct and outer heat exchange air duct structure; the inner heat exchange air duct includes a plurality of inner air inlet ducts 29, inner diversion ducts 210 and a plurality of inner air discharge ducts 211. The plurality of inner air inlet ducts 29 and the plurality of inner air discharge ducts 211 are respectively opened at both ends of the same side of the heat exchange plate 28, and the plurality of inner air inlet ducts 29 and the plurality of inner air discharge ducts 211 are communicated through the inner diversion ducts 210; the outer heat exchange air duct includes a plurality of outer air inlet ducts 212, outer diversion ducts 213 and a plurality of outer air discharge ducts 214. The plurality of outer air inlet ducts 212 and the plurality of outer air discharge ducts 214 are respectively opened at both ends of the same side of the heat exchange plate 28, and the plurality of outer air inlet ducts 212 and the plurality of outer air discharge ducts 214 are communicated through the outer diversion ducts 213; The inner air supply component includes an inner dust-proof net 27, an inner air guide cover 25 and an inner fan 26. The inner dust-proof net 27 is installed on the inner air inlet surface of the heat dissipation frame 21 to separate the inlet of the inner air inlet duct 29 from the inside of the cabinet 1. The inner air guide cover 25 is installed on the inner air discharge surface of the heat dissipation frame 21 and covers the outlet of the inner air discharge duct 211. The inner fan 26 is fixedly installed inside the outlet of the inner air guide cover 25; the outer air supply component includes an outer dust-proof net 24, an outer air guide cover 22 and an outer fan 23. The outer dust-proof net 24 is installed on the outer air inlet surface of the heat dissipation frame 21 to separate the inlet of the outer air inlet duct 212 from the outside. The outer air guide cover 22 is installed on the outer air discharge surface of the heat dissipation frame 21 and covers the outlet of the outer air discharge duct 214. The outer fan 23 is fixedly installed inside the outlet of the outer air guide cover 22; During heat dissipation, the inner fan 26 sucks air into all the inner heat exchange air ducts through the inner air guide cover 25, so as to generate a negative pressure suction force in the inner heat exchange air ducts. At this time, the air inside the cabinet 1 enters the inner air inlet duct 29 through the inner dust-proof net 27, and is transported from the inner air inlet duct 29 to the inner air discharge duct 211 through the inner diversion duct 210, and finally is transported back to the inside of the cabinet 1 through the inner air guide cover 25 and the inner fan 26, so that the air inside the cabinet 1 is circulated and transported through the inner heat exchange air duct on one side of the heat exchange plate 28. Correspondingly, the outer fan 23 sucks air into all the outer heat exchange air ducts through the outer air guide cover 22, so as to generate a negative pressure suction force in the outer heat exchange air ducts. At this time, the relatively cold air outside enters the outer air inlet duct 212 through the outer dust-proof net 24, and is transported from the outer air inlet duct 212 to the outer air discharge duct 214 through the outer diversion duct 213, and finally is discharged through the outer air guide cover 22 and the outer fan 23, so that the outside air is circulated and transported through the outer heat exchange air duct on the other side of the heat exchange plate 28. At this time, the relatively cold air in the outer heat exchange air duct exchanges heat with the relatively hot air in the inner heat exchange air duct through the heat exchange plate 28, so that the temperature of the air inside the inner heat exchange air duct is reduced, thereby dissipating heat for the inside of the cabinet 1.

[0024] Embodiment Three See also Figure 2 , Figures 4-8 As shown, the difference between this embodiment and the above embodiment is that the sealing partition assembly includes a plurality of sealing grooves 310, which are respectively opened on both sides of a plurality of heat exchange plates 28 and communicated with the outer guide channel 213 or the inner guide channel 210 on the heat exchange plate 28, a sealing plug 32 is slidably installed in the sealing groove 310, one end of the sealing plug 32 is threadedly installed with a screw 311 through an internal threaded hole, and the screw 311 is rotatably installed in the interior of the sealing groove 310, and a driven bevel gear 314 is fixedly installed at one end of the screw 311; a driving shaft 312 connected to the heat exchange plate 28 is rotatably installed in the interior of the heat dissipation frame 21, a motor 31 connected to the driving shaft 312 is fixedly installed at the top of the heat dissipation frame 21, the driving shaft 312 passes through the inner end of the sealing groove 310, and a plurality of active bevel gears 313 are fixedly installed on the driving shaft 312, and the plurality of active bevel gears 313 are respectively meshed and transmission-connected with the driven bevel gears 314 in the corresponding sealing groove 310; The connecting component includes a plurality of groups of regulating guide grooves, each group of regulating guide grooves includes an upper air inlet guide groove 33, a lower air inlet guide groove 35, an upper air exhaust guide groove 34 and a lower air exhaust guide groove 36. The upper air inlet guide groove 33 and the upper air exhaust guide groove 34 are arranged on the side of the heat exchange plate 28 having the inner heat exchange air duct, and are respectively connected to the two ends of the inner guide channel 210. The lower air inlet guide groove 35 and the lower air exhaust guide groove 36 are arranged on the side of the heat exchange plate 28 having the outer heat exchange air duct, and are respectively connected to the two ends of the outer guide channel 213.

When ventilation and heat dissipation are required, the motor 31 drives the drive shaft 312 to rotate, so that the drive shaft 312 drives a plurality of driving bevel gears 313 thereon to rotate synchronously. At this time, the driving bevel gear 313 meshes with and drives the driven bevel gear 314 to rotate, thereby driving the screw 311 to rotate. When the screw 311 rotates, it drives the corresponding sealing plug 32 outwards into the outer flow channel 213 and the inner flow channel 210 through thread transmission, so that the sealing plug 32 seals and partitions the outer flow channel 213 and the inner flow channel 210 from the middle, and divides both the outer flow channel 213 and the inner flow channel 210 into left and right parts. At the same time, the screw 311 drives the lead screw 318 to rotate synchronously through the meshing transmission of the transmission bevel gear 315 and the synchronous bevel gear 316, so that the lead screw 318 drives the sealing valve core 37 to slide and contract into the side chute 317, thereby opening the upper air inlet guide groove 33, the lower air inlet guide groove 35, the upper air exhaust guide groove 34, and the lower air exhaust guide groove 36.

At the same time, the outside air enters the inside of the cabinet 1 through the outer air inlet duct 212, the left side of the outer flow channel 213, the lower air inlet guide groove 35, the air inlet through hole 38, the upper air inlet guide groove 33, the left side of the inner flow channel 210, and the inner air inlet duct 29, thereby ventilating and dissipating heat in the cabinet 1. By directly ventilating and dissipating heat, the heat dissipation effect on the inside of the cabinet 1 is improved.

At this time, the air in the outer heat exchange air duct exchanges heat and cools the air in the inner heat exchange air duct through the heat exchange component, thereby dissipating heat inside the cabinet 1; When the external temperature is high and heat exchange by air alone is insufficient to dissipate heat inside the cabinet 1, the air inlet end and the air outlet end of the internal heat exchange air duct are sealed off by the sealing partition assembly, and at the same time, the air inlet end and the air outlet end of the external heat exchange air duct are sealed off. Then, through the connecting assembly, the air inlet end of the internal heat exchange air duct can be connected to the air inlet end of the external heat exchange air duct, and at the same time, the air outlet end of the internal heat exchange air duct is connected to the air outlet end of the external heat exchange air duct.
