Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly relates to a charging pile with efficient heat dissipation. Background Art

[0002] New energy charging piles, also known as electric vehicle charging stations or electric vehicle power supply devices, are devices that provide electric energy for electric vehicles, enabling electric vehicles to store sufficient power to support their operation.

[0003] The heat dissipation of new energy charging piles is a key factor to ensure their stable operation and extend their service life. After retrieval, a Chinese patent with the publication number CN218228680U discloses a charging pile with uniform heat dissipation function, including a housing, an operation table is arranged on the outer wall of the housing, the housing is also connected with a charging plug, a core component is arranged inside the charging pile, the core component is connected to the inner wall of the housing, the core component is electrically connected to the operation table and the charging plug respectively, a first ventilation window is opened at the upper end of the housing, a protective net is arranged on the first ventilation window, the four peripheral edges of the protective net are connected to the outer wall of the housing, a blower fan is arranged below the protective net, the blower fan is connected to the inner wall of the housing, a second ventilation window is opened at the lower end of the housing, a protective frame is arranged outside the second ventilation window, an exhaust fan is arranged inside the protective frame, a wire winding component is arranged on the inner wall of the housing, multiple wires are led out from the core component, and the multiple wires are uniformly arranged in the wire winding component. The scheme can improve the problem of low heat dissipation efficiency of electric vehicle charging piles in the prior art. However, when the above scheme is actually used, there are still the following deficiencies.

[0004] During the use of the charging pile, dust in the external environment is likely to adhere to the dust-proof net. The accumulation of dust will cause the dust-proof net to be blocked. The accumulation and blockage of dust on the dust-proof net will hinder the heat dissipation of the internal electrical components of the charging pile. The charging pile will generate a certain amount of heat during operation. If the heat cannot be dissipated in time, it will cause the internal temperature of the charging pile to rise. Long-term high-temperature operation will not only reduce the working efficiency of the charging pile, but may also cause overheating failures and even safety hazards such as fires.

[0063] As a preferred technical solution of the present invention, the current-limiting directions of the two check valves are opposite.

[0064] The present invention has the following beneficial effects:

[0065] 1. During use, the air inside and outside the charging pile dissipates heat through convection. The dust-proof sleeve effectively blocks the intrusion of external dust, ensuring the cleanliness inside the charging pile. At the same time, the synchronous rotation of the motor drives the rotation of the dust-proof sleeve. This dynamic process not only enhances the dust-proof effect but also provides a basis for subsequent dust cleaning work. More importantly, through the cooperation of bevel gears and eccentric wheels, the vibration of the dust cleaning plate is driven, and the bristles on it can continuously brush the surface of the dust-proof sleeve, effectively brushing off the attached dust, avoiding the blockage of the dust-proof sleeve, and thus ensuring the continuous heat dissipation performance of the charging pile. The combination of this rotatable dust-proof sleeve and the vibrating dust cleaning plate not only improves the dust-proof efficiency compared with the traditional fixed dust-proof net structure but also realizes an automated dust cleaning process, ensuring the long-term stable operation of the charging pile;

[0066] 2. A number of axial flow blades provided on the air suction member perform an air extraction action when rotating, effectively extracting the air in the suction pipe connected to the dust suction cylinder. This design enables the suction ports on the two suction pipes to efficiently absorb the dust brushed off by the brush bristles. Subsequently, through the operation of the air suction member, the dust is discharged into the dust collection box for collection. This entire process not only prevents the dust from falling into the interior of the charging pile, effectively preventing the secondary pollution of the dust to the dust-proof sleeve and the internal components of the charging pile but also ensures the cleanliness and safety of the operating environment of the charging pile, further improving the heat dissipation performance and long-term use reliability of the charging pile;

[0067] 3. The air guiding structure integrated inside the dust-proof sleeve, including the air guiding cover, the air guiding pipe, and a number of flow guiding plates inside the air guiding pipe, jointly constructs an S-shaped air flow channel. This design ensures that the air in the external environment can pass through an extended and tortuous path before entering the interior of the charging pile, not only enhancing the stability of the air flow but also improving the heat dissipation efficiency. Furthermore, the cooling pipe fixed on the air guiding pipe cools the gas flowing inside the air guiding pipe by accumulating low-temperature coolant, effectively reducing the temperature of the gas entering the interior of the charging pile. Especially in a high-temperature environment in summer, even when the air inside the charging pile is discharged and the external hot air replenishes, it can be effectively cooled through this cooling mechanism, thus avoiding the overheating problem of the charging pile caused by the high-temperature environment. This comprehensive design not only guarantees the heat dissipation performance of the charging pile but also extends its service life and improves the overall operation stability and reliability;

[0068] 4. Through the air duct and several flow deflectors, an S-shaped air flow channel is created. This design not only optimizes the air flow path but also significantly extends the flow duration of the gas in the air duct. Under the precise guidance of the flow deflectors, the gas is forced to travel along a tortuous path. During this process, there is more contact time and heat exchange opportunity between the gas and the low-temperature cooling pipe. This increased heat exchange time ensures that the cooling pipe can fully exert its cooling effect;

[0069] 5. Through the built-in circulating flow structure, the efficient recycling of the coolant is achieved. This structure ensures the continuous circulating flow of the coolant between the cooling pipe and the refrigeration compressor. When the coolant flows through the refrigeration compressor, its temperature is significantly reduced, thus ensuring that the cooling pipe is always filled with low-temperature coolant. This design not only improves the cooling efficiency of the cooling pipe for the gas but also ensures the lasting stability of the cooling effect. Through the circulating flow structure, the coolant can continuously obtain cold energy from the refrigeration compressor and then effectively absorb and carry away the heat of the gas in the air duct in the cooling pipe, realizing the continuous cooling of the gas entering the charging pile. This innovative design significantly enhances the thermal management ability of the charging pile and can ensure the stability of the internal temperature of the charging pile even in extremely high-temperature environments.

DETAILED DESCRIPTION

[0082] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0083] Reference Figures 1-11 A charging pile with efficient heat dissipation comprises a charging pile shell 1; a heat dissipation port 2, which is opened on the side of the charging pile shell 1 and is in the shape of a long strip; two side panels 3, both of which are arranged inside the charging pile shell 1, and the two side panels 3 are arranged opposite to each other; a dustproof net cylinder 4, which is fixed between the two side panels 3, and is a tubular structure with openings 5 ​​at both ends, and the dustproof net cylinder 4 is arranged opposite to the heat dissipation port 2. The air inside and outside the charging pile shell 1 is convected through the heat dissipation port 2, and the dustproof sleeve facing the heat dissipation port 2 can prevent dust in the external environment from entering the interior of the charging pile shell 1, thereby playing a dustproof role; the opening 5 is opened in the middle position of one of the side panels 3; the mounting plate 6 is fixed inside the charging pile shell 1.

[0084] The charging pile also includes a rotating structure, which is arranged on the mounting plate 6, and the rotating structure includes: a motor 71, which is installed on the mounting plate 6; a drive shaft 72, which is fixed on the output shaft of the motor 71, and at least two bearing seats are fixed on the mounting plate 6, and the drive shaft 72 is rotatably installed on the two bearing seats; a rotating rod 73, which is fixed at the middle position of the side surface of one of the side plates 3; a transmission member 74, and the drive shaft 72 and the rotating rod 73 are connected by transmission via the transmission member 74.

[0085] The charging pile further includes a dust cleaning structure, which is arranged on the mounting plate 6. The dust cleaning structure includes: a dust cleaning plate 81, which is arranged below the mounting plate 6 and is directly above the dust-proof net cylinder 4; a plurality of bristles 82, which are all arranged on the bottom surface of the dust cleaning plate 81; a limiting port 83, which is opened on the mounting plate 6; a limiting block 84, which is fixed on the top surface of the dust cleaning plate 81, and the limiting block 84 is slidably arranged in the limiting port 83; a limiting plate 85, which is fixed on the top surface of the limiting block 84, and the bottom surface of the limiting plate 85 is in mutual contact with the top surface of the mounting plate 6; a tension spring 86, one end of which is connected to the limiting plate 85 and the other end of which is connected to the mounting plate 6.

[0086] The charging pile further includes a vibration structure, which is arranged on the mounting plate 6. The vibration structure includes: a fixing frame 101, which is fixed on the side surface of the mounting plate 6, and an assembly port is opened on the fixing frame 101; a rotating shaft 102, which is rotatably installed in the assembly port; an eccentric wheel 103, which is fixedly sleeved on the rotating shaft 102, and the eccentric wheel 103 is eccentrically arranged with respect to the rotating shaft 102; two bevel gears 104, one of the bevel gears 104 is fixedly sleeved on the driving shaft 72, and the other bevel gear 104 is fixedly sleeved on the rotating shaft 102, and the two bevel gears 104 are meshed with each other; a push rod 105, which is fixed on the top surface of the limiting plate 85, and the end of the push rod 105 far from the limiting plate 85 is arranged directly opposite to the eccentric wheel 103.

[0087] When the charging pile housing 1 operates, the motor 71 operates synchronously, driving the driving shaft 72 to rotate. When the driving shaft 72 rotates, it can drive the rotating rod 73 to rotate through the transmission member 74, and the rotating rod 73 drives the corresponding mounting plate 6 to rotate, which causes the dust-proof sleeve to rotate accordingly. In addition, when the driving shaft 72 rotates, it can also drive the rotating shaft 102 to rotate through the two meshing bevel gears 104, and the eccentric wheel 103 on the rotating shaft 102 will also rotate accordingly. During the rotation of the eccentric wheel 103, it will continuously squeeze the push rod 105. When the eccentric wheel 103 squeezes the push rod 105, the push rod 105 can drive the limiting plate 85 to move. When the eccentric wheel 103 is separated from the push rod 105, the limiting plate 85 will reset under the elastic force of the tension spring 86. Therefore, with the rotation of the eccentric wheel 103, the limiting plate 85 will produce a vibration effect, which causes the dust cleaning plate 81 to vibrate continuously. During the vibration of the dust cleaning plate 81, the bristles 82 on it can continuously brush the dust-proof sleeve directly below the dust cleaning plate 81 and brush off the dust attached to the surface of the dust-proof sleeve, playing a role in cleaning the dust-proof sleeve.

[0088] The charging pile further includes a gas guiding structure disposed inside the dust-proof net cylinder 4. The gas guiding structure includes: a wind guiding cover 121 placed inside the dust-proof net cylinder 4, and an arc surface adapted to the dust-proof net cylinder 4 is provided on the wind guiding cover 121; a wind guiding pipe 122 fixed to the wind guiding cover 121 and communicating with the wind guiding cover 121; a cooling pipe 123 fixedly sleeved on the wind guiding pipe 122, and a coolant is stored inside the cooling pipe 123; a plurality of flow guiding plates 124 are all fixed inside the wind guiding pipe 122, each flow guiding plate 124 is inclined, and the plurality of flow guiding plates 124 and the wind guiding pipe 122 together form an S-shaped air flow channel.

[0089] When the air in the external environment enters the inside of the charging pile housing 1 through the heat dissipation port 2, the air flow will enter the wind guiding cover 121 and enter the wind guiding pipe 122 under the guiding action of the wind guiding cover 121. A plurality of flow guiding plates 124 are arranged inside the wind guiding pipe 122, and the plurality of flow guiding plates 124 and the wind guiding pipe 122 together form an S-shaped air flow channel. The gas passes through this air flow channel and finally enters the inside of the charging pile housing 1. Further, a cooling pipe 123 is fixed to the wind guiding pipe 122, and a low-temperature coolant is stored inside the cooling pipe 123. Therefore, the cooling pipe 123 can cool the gas flowing inside the wind guiding pipe 122, thereby cooling the gas entering the inside of the charging pile housing 1. This design can ensure the heat dissipation performance of the charging pile housing 1. In summer, the ambient temperature around the charging pile housing 1 is very high. Even if the air inside the charging pile housing 1 is discharged, the hot air in the external environment will replenish the inside of the charging pile housing 1. This gas cooling mechanism can effectively solve this problem.

[0090] A dust collection structure is provided on the mounting plate 6. The dust collection structure includes: two dust suction pipes 111, which are respectively fixed on both sides of the mounting plate 6, and the two dust suction pipes 111 are connected and communicated through a U-shaped pipe; several dust suction ports 112, which are respectively opened on the two dust suction pipes 111; a fixing rod 113, which is fixed on the mounting plate 6; a dust suction cylinder 114, which is fixed at one end of the fixing rod 113 away from the mounting plate 6, and through holes are opened at both ends of the dust suction cylinder 114, and the driving shaft 72 passes through the two through holes; an air suction member 115, which is fixedly sleeved on the driving shaft 72, and the air suction member 115 is placed inside the dust suction cylinder 114. The air suction member 115 includes a sleeve and several axial flow blades. The sleeve is fixedly sleeved on the driving shaft 72, and several axial flow blades are all fixed on the sleeve, and several axial flow blades are circumferentially arrayed; a dust collection box 116, which is installed on the side of the mounting plate 6; an air inlet pipe, one end of which is connected and communicated with the dust suction cylinder 114, and the other end of which is connected and communicated with one of the dust suction pipes 111; an air outlet pipe, one end of which is connected and communicated with the dust suction cylinder 114, and the other end of which is connected and communicated with the dust collection box 116. When the driving shaft 72 rotates, it can also drive the air suction member 115 to rotate. There are several axial flow blades provided in the air suction member 115, and when several axial flow blades rotate, they can perform an air extraction action. Therefore, when the air suction member 115 rotates, it can extract the air in the dust suction pipe 111 connected to the dust suction cylinder 114. In this case, several dust suction ports 112 on the two dust suction pipes 111 can absorb the dust brushed off by the bristles 82, and the air suction member 115 discharges the dust into the dust collection box 116, realizing the collection of dust, preventing the dust from falling into the interior of the charging pile housing 1, and at the same time preventing the dust from causing secondary pollution to the dust-proof sleeve.

[0091] Inside the charging pile housing 1, a refrigeration compressor 13 is installed. A circulating flow structure is provided on the mounting plate 6. The circulating flow structure includes: a connecting rod 141 fixed to the fixing bracket 101; a mounting cylinder 142 fixed to the end of the connecting rod 141 away from the fixing bracket 101. An avoidance opening adapted to the rotating shaft 102 is provided on the bottom surface of the mounting cylinder 142. The top end of the rotating shaft 102 passes through the avoidance opening and extends into the interior of the mounting cylinder 142; a rotating block 143 rotatably installed in the mounting cylinder 142, and the rotating block 143 is fixed to the top end of the rotating shaft 102; a moving block 144 slidably disposed in the mounting cylinder 142; a chute 145 opened on the inner surface of the mounting cylinder 142; a slider 146 fixed to the moving block 144, and the slider 146 slides in the chute 145; a bladder 147, one end of which is connected to the inner top surface of the mounting cylinder 142, and the other end is connected to the moving block 144; two mounting pipes 148, one end of each of which is communicated with the bladder 147. The other end of one of the mounting pipes 148 is communicated with the cooling pipe 123, and the other end of the other mounting pipe 148 is communicated with the refrigeration compressor 13. The refrigeration compressor 13 and the cooling pipe 123 are communicated through a return pipe; two one-way valves 149 are respectively installed on the two mounting pipes 148. The current-limiting directions of the two one-way valves 149 are opposite, aiming to make the coolant circulate in the cooling pipe 123 and the refrigeration compressor 13. When the coolant passes through the refrigeration compressor 13, the temperature of the coolant is reduced, so as to ensure that the cooling pipe 123 always has low-temperature coolant. This design ensures the cooling effect of the cooling pipe 123 on the gas.

[0092] The specific working principle of the present invention is as follows:

[0093] When the charging pile proposed by the present invention is in use, the air inside and outside the charging pile housing 1 convects through the heat dissipation port 2. The dust-proof sleeve facing the heat dissipation port 2 can prevent dust in the external environment from entering the interior of the charging pile housing 1, playing a dust-proof role. In addition, when the charging pile housing 1 operates, the motor 71 rotates synchronously, driving the drive shaft 72 to rotate. When the drive shaft 72 rotates, it can drive the rotating rod 73 to rotate through the transmission member 74, and the rotating rod 73 drives the corresponding mounting plate 6 to rotate, which causes the dust-proof sleeve to rotate accordingly. In addition, when the drive shaft 72 rotates, it can also drive the rotating shaft 102 to rotate through two meshing bevel gears 104, and the eccentric wheel 103 on the rotating shaft 102 will also rotate accordingly. During the rotation of the eccentric wheel 103, it will continuously squeeze the ejector rod 105. When the eccentric wheel 103 squeezes the ejector rod 105, the ejector rod 105 can drive the limit plate 85 to move. When the eccentric wheel 103 separates from the ejector rod 105, the limit plate 85 will reset under the elastic force of the tension spring 86. Therefore, with the rotation of the eccentric wheel 103, the limit plate 85 will produce a vibrating effect, which causes the dust cleaning plate 81 to vibrate continuously. During the vibration of the dust cleaning plate 81, the bristles 82 thereon can continuously brush the dust-proof sleeve directly below the dust cleaning plate 81 and brush off the dust attached to the surface of the dust-proof sleeve, playing a role in cleaning the dust-proof sleeve. Based on the above process, the vibrating dust cleaning plate 81 can comprehensively clean the rotating dust-proof sleeve, avoid dust clogging the dust-proof sleeve, thereby ensuring the heat dissipation performance of the charging pile housing 1. The rotatable dust-proof sleeve replaces the traditional fixed dust-proof net structure, and this dynamic process provides a basis for the dust cleaning work. It should be noted that the transmission member 74 adopts a belt drive transmission method, and the transmission member 74 decelerates the rotation speed of the drive shaft 72, which enables the dust-proof sleeve to rotate slowly and ensures the dust cleaning effect of the dust cleaning plate 81 on the dust-proof sleeve.

[0094] In addition, when the drive shaft 72 rotates, it can also drive the air suction member 115 to rotate. The air suction member 115 is provided with a plurality of axial flow blades. When the plurality of axial flow blades rotate, they can perform an air extraction action. Therefore, when the air suction member 115 rotates, it can extract the air in the suction pipe 111 connected to the dust suction cylinder 114. In this case, a plurality of dust suction ports 112 on the two suction pipes 111 can absorb the dust brushed off by the bristles 82, and the air suction member 115 discharges the dust into the dust collection box 116, realizing the collection of dust, preventing dust from falling into the interior of the charging pile housing 1, and at the same time preventing the dust from causing secondary pollution to the dust-proof sleeve.

[0095] A gas guiding structure for guiding air flow is also provided inside the dust-proof sleeve. When the air in the external environment enters the inside of the charging pile housing 1 through the heat dissipation port 2, the air flow will enter the air guiding cover 121 and enter the air guiding pipe 122 under the guiding action of the air guiding cover 121. A number of flow guiding plates 124 are arranged in the air guiding pipe 122. The number of flow guiding plates 124 and the air guiding pipe 122 together form an S-shaped air flow channel. The gas passes through this air flow channel and finally enters the inside of the charging pile housing 1.

[0096] Furthermore, a cooling pipe 123 is fixed on the air guiding pipe 122. A low-temperature coolant is stored in the cooling pipe 123. Therefore, the cooling pipe 123 can cool the gas flowing inside the air guiding pipe 122, thereby cooling the gas entering the inside of the charging pile housing 1. This design can ensure the heat dissipation performance of the charging pile housing 1. In summer, the ambient temperature around the charging pile housing 1 is very high. Even if the air inside the charging pile housing 1 is discharged, the hot air in the external environment will supplement the inside of the charging pile housing 1. This gas cooling mechanism can effectively solve this problem. It is worth noting that under the guiding action of a number of flow guiding plates 124, the gas can flow along an S-shaped path inside the air guiding pipe 122. This can extend the flow time of the gas inside the air guiding pipe 122, so that there is more heat exchange time between the gas and the low-temperature cooling pipe 123, ensuring the cooling effect of the cooling pipe 123 on the gas.

[0097] A circulating flow structure for the circulating flow of the coolant is also provided inside the charging pile housing 1. The purpose is to make the coolant circulate between the cooling pipe 123 and the refrigeration compressor 13. When the coolant passes through the refrigeration compressor 13, the temperature of the coolant is reduced, so as to ensure that there is always low-temperature coolant in the cooling pipe 123. This design ensures the cooling effect of the cooling pipe 123 on the gas. Specifically, while the rotating shaft 102 drives the eccentric wheel 103 to rotate, it can also drive the rotating block 143 connected to it to rotate. Since the rotating block 143 and the moving block 144 together form a cylindrical structure, the rotating block 143 and the moving block 144 are of the same size, and inclined surfaces are provided at the opposite ends of the rotating block 143 and the moving block 144. The outer edges of the rotating block 143 and the moving block 144 are in mutual contact with the inner surface of the mounting cylinder 142. Therefore, during the rotation of the rotating block 143, the inclined surface part of it can squeeze the inclined surface part of the moving block 144. Under the limiting action of the sliding groove 145 and the sliding block 146, the moving block 144 cannot rotate following the rotating block 143. Therefore, the moving block 144 will move under the squeezing action of the rotating block 143. At the same time, with the elasticity of the bladder 147 itself, the moving block 144 reciprocates inside the mounting cylinder 142.

[0098] In this process, the bladder 147 is periodically squeezed and stretched. Further, the liquid flow limiting directions of the two one-way valves 149 are opposite. One of the one-way valves 149 limits the liquid to only enter the interior of the bladder 147, and the other one-way valve 149 limits the liquid to only flow out of the bladder 147. Therefore, when the bladder 147 is squeezed, the coolant in the bladder 147 will be pressed into the refrigeration compressor 13. When the bladder 147 resumes its original state, the bladder 147 will perform a pumping action and pump the coolant in the cooling pipe 123 into it. Based on the above process, along with the rotation of the rotating shaft 102, the coolant will circulate between the cooling pipe 123, the bladder 147 and the refrigeration compressor 13, enabling the refrigeration compressor 13 to cool down the coolant.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
