Description

Technical Field

[0001] This utility model relates to the field of new energy charging, specifically to a new energy charging pile device that integrates antifreeze and heat dissipation. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging piles are divided into public and private charging piles, and from a charging method perspective, they are divided into AC charging piles and DC charging piles. Currently, the temperature control method used inside charging piles is mainly liquid temperature control. Some units use tap water directly to save costs, which can easily lead to safety accidents. Using dedicated non-conductive coolants is more expensive and not conducive to widespread use.

[0003] In summary, traditional charging pile thermal management solutions have the following drawbacks:

[0004] 1. The separate design of the antifreeze and heat dissipation systems results in low space utilization and thermal conflicts.

[0005] 2. Low-temperature heating relies on heating wires, which consumes a lot of energy and poses a risk of localized overheating. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-4 As shown, this utility model provides a new energy charging pile device with integrated antifreeze and heat dissipation, including a charging pile shell 1, a heat dissipation hole on the charging pile shell 1, an antifreeze and heat dissipation component 2 inside the charging pile shell 1, an intelligent control component 3 on one side of the antifreeze and heat dissipation component 2, and a slot antifreeze component 4 on the periphery of the charging pile shell 1.

[0028] According to the embodiment of the present utility model, the antifreeze and heat dissipation integrated new energy charging pile device includes an antifreeze and heat dissipation component 2, which includes a component mounting plate 201. The component mounting plate 201 is installed inside the charging pile shell 1. Heat exchange fins 212 are installed around the component mounting plate 201. Heat exchange tubes 202 are installed inside the heat exchange fins 212. One end of the heat exchange tubes 202 is connected to a heat exchange mechanism 203. The heat exchange mechanism 203 is embedded inside the charging pile shell 1.

[0029] Example 1

[0030] The heat exchange mechanism 203 can be an air conditioner, which has the function of supplying cold and hot air. The cold or hot air is supplied to the heat exchange tube to deliver cold or hot air to the heat exchange fins 212 to ensure the normal temperature of the gas mounting plate 201, so that the internal components can maintain normal operation and are not easily affected by the external environment.

[0031] Example 2

[0032] Because the air conditioner is large, it increases the usable area. When in use, one air conditioner can supply hot or cold air to multiple charging stations.

[0033] Example 3

[0034] In this embodiment, the heat exchange mechanism 203 is equipped with a first thermoelectric cooler 204 and a second thermoelectric cooler 205. The working surface of the first thermoelectric cooler 204 is the cold surface, and the working surface of the second thermoelectric cooler 205 is the hot surface. A mounting housing is appropriately configured to install the thermoelectric coolers into the housing. A connecting pipe 206 is connected to one side of the heat exchange mechanism 203. One end of the connecting pipe 206 is connected to the output end of a conveying fan 207, and the input end of the conveying fan 207 is connected to the end of the heat exchange tube 202 furthest from the heat exchange mechanism 203. An isolation valve 208 is installed inside the heat exchange tube 202. A ventilation inlet pipe 209 and a ventilation outlet pipe 210 are connected to one side of the heat exchange pipe 202. The ventilation inlet pipe 209 and the ventilation outlet pipe 210 penetrate the outer shell 1 of the charging pile. A ventilation installation valve 211 is installed inside the ventilation inlet pipe 209 and the ventilation outlet pipe 210. The cold end of the first semiconductor refrigeration chip 204 and the hot end of the second semiconductor refrigeration chip 205 are located inside the heat exchange mechanism 203, respectively. The hot end of the first semiconductor refrigeration chip 204 and the cold end of the second semiconductor refrigeration chip 205 are located in the outside air, respectively. A dust filter 5 is connected to one side of the ventilation inlet pipe 209. The dust filter 5 achieves the function of air intake and dust prevention.

[0035] Through the above technical solution, the component mounting plate 201 installs the components of the charging pile. When the temperature sensor 301 detects that the temperature of the charging pile shell 1 is too high, the controller 302 starts the conveying fan 207, closes the isolation valve 208, opens the ventilation mounting valve 211, starts the first semiconductor refrigeration chip 204, and closes the second semiconductor refrigeration chip 205. At this time, under the isolation of the isolation valve 208, the external air enters the connecting pipe 206 through the ventilation inlet pipe 209 and the heat exchange pipe 202. Then, the external air enters the heat exchange mechanism 203 through the external air inlet pipe 206. The first semiconductor refrigeration chip 204 cools the external air into cold air. The cold air cools the heat exchange fins 212 through the heat exchange pipe 202. The heat exchange fins 212 can then cool the component mounting plate 201. The air after heat exchange is discharged through the ventilation outlet pipe 210.

[0036] When the temperature sensor 301 detects that the component mounting plate 201 is too cold, the controller 302 starts the conveyor fan 207, opens the isolation valve 208, closes the ventilation mounting valve 211, closes the first semiconductor refrigeration chip 204, and starts the second semiconductor refrigeration chip 205. At this time, the air circulates in the heat exchange tube 202. When the air in the heat exchange tube 202 passes through the heat exchange mechanism 203, the second semiconductor refrigeration chip 205 heats the air in the heat exchange tube 202, so that the hot air heats the heat exchange fins 212 through the heat exchange tube 202, and the heat exchange fins 212 can heat the component mounting plate 201.

[0037] The first thermoelectric cooler 204 (hot end) and the second thermoelectric cooler 205 (cold end) can be connected to a fan mounted on the outer surface of the charging pile housing 1, depending on the actual situation. When the fan blows air onto the hot end of the first thermoelectric cooler 204 and the cold end of the second thermoelectric cooler 205, they exchange heat with a large amount of external air, ensuring the normal cooling of the first thermoelectric cooler 204 and the normal heating of the second thermoelectric cooler 205. The working principle of the thermoelectric cooler is conventional technology and is not detailed here. The cost of thermoelectric coolers is relatively low; their effectiveness should be considered when selecting a model to ensure heating and cooling performance.

[0038] Example 4

[0039] like Figure 3As shown, the intelligent control component 3 in this embodiment includes a temperature sensor 301, a controller 302 is provided on one side of the temperature sensor 301, the temperature sensor 301 and the controller 302 are mounted on one side of the component mounting plate 201, a smoke sensor 303 is installed on the inner wall of the charging pile housing 1, a buzzer 304 is provided on one side of the smoke sensor 303, and the first semiconductor cooling chip 204, the second semiconductor cooling chip 205, the conveying fan 207, the isolation valve 208, the ventilation mounting valve 211, the temperature sensor 301, the smoke sensor 303 and the buzzer 304 are electrically connected to the controller 302 respectively.

[0040] Through the above technical solution, by setting a temperature sensor 301, the temperature of the component mounting plate 201 can be easily detected. After the smoke sensor 303 is triggered, the controller 302 will sound an alarm through the buzzer 304, thereby achieving the function of fire warning.

[0041] Example 5

[0042] like Figure 4 As shown, the slot antifreeze component 4 in this embodiment includes a charging slot 401, which is symmetrically installed on both sides of the charging pile housing 1. A coil mounting slot 402 is provided inside the charging slot 401, and an annular eddy current heating coil 403 is installed inside the coil mounting slot 402. The annular eddy current heating coil 403 is electrically connected to the controller 302.

[0043] Through the above technical solution, the controller 302 activates the annular eddy current heating coil 403 inside the coil mounting slot 402 and maintains it at 5℃-7℃, thereby achieving the effect of preventing the charging gun inserted into the charging slot 401 from freezing.

[0044] The working principle of the ring heating coil 403 utilizes the electromagnetic induction effect. First, current flows through a finely wound ring-shaped or specifically shaped copper tube coil. This coil serves as the current transmission path. When the current flows through the coil, a powerful, rapidly changing magnetic field is generated within it. This magnetic field is characterized by its rapidly changing polarity. When metal or other materials to be heated are placed inside the coil, the magnetic field penetrates these materials, inducing eddy currents within the material in the opposite direction to the heating current. These eddy currents, generated within the material, act like an internal generator. Due to the material's own resistance, the eddy currents convert electrical energy into a large amount of heat energy, i.e., Joule heating. This heat energy causes the material's temperature to rise rapidly, thus heating the metal material. The ring heating coil 403 utilizes the coil's action to generate eddy currents, which rapidly inductively heat the metal inside the charging gun. The controller 302 controls the ring heating coil 403 to heat at a certain frequency, preventing overheating of the charging port and also preventing the charging gun from freezing.

[0045] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0046] In summary, with the help of the above-mentioned technical solution of this utility model, the component mounting plate 201 installs the components of the charging pile. When the temperature sensor 301 detects that the temperature of the charging pile shell 1 is too high, the controller 302 starts the conveying fan 207, closes the isolation valve 208, opens the ventilation mounting valve 211, starts the first semiconductor cooling chip 204, and closes the second semiconductor cooling chip 205. At this time, under the isolation of the isolation valve 208, the external air enters the connecting pipe 206 through the ventilation inlet pipe 209 and the heat exchange pipe 202. Then, the external air connecting pipe 206 enters the heat exchange mechanism 203. The external air is cooled into cold air by the first semiconductor cooling chip 204. The cold air is cooled by the heat exchange fins 212 through the heat exchange pipe 202. The heat exchange fins 212 can then cool the component mounting plate 201. The air after heat exchange is discharged through the ventilation outlet pipe 210.

[0047] When the temperature sensor 301 detects that the component mounting plate 201 is too cold, the controller 302 starts the conveyor fan 207, opens the isolation valve 208, closes the ventilation mounting valve 211, closes the first semiconductor refrigeration chip 204, and starts the second semiconductor refrigeration chip 205. At this time, the air circulates in the heat exchange tube 202. When the air in the heat exchange tube 202 passes through the heat exchange mechanism 203, the second semiconductor refrigeration chip 205 heats the air in the heat exchange tube 202, so that the hot air heats the heat exchange fins 212 through the heat exchange tube 202, and the heat exchange fins 212 can heat the component mounting plate 201.

[0048] By setting a temperature sensor 301, the temperature of the component mounting plate 201 can be easily detected. After the smoke sensor 303 is triggered, the controller 302 will sound an alarm through the buzzer 304, thereby achieving the function of fire warning.

[0049] The controller 302 activates the annular heating coil 403 inside the coil mounting slot 402, maintaining it at 5℃-7℃, thereby preventing the charging gun inserted into the charging slot 401 from freezing.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
