[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Specific Implementation Example 1: Reference Figure 1 , Figure 2 A charging pile with AC / DC integration includes a charging pile body 1. The bottom of the charging pile body 1 is provided with a base 2. The base 2 is provided with a water tank 3 and a water pump 4 connected to the water tank 3. The interior of the charging pile body 1 is provided with a cooler 5, a cold water output pipe 6 and a hot water return pipe 7. The output end of the water pump 4 is connected to the cooler 5. One end of the cooler 5 is connected to the cold water output pipe 6 and the other end is connected to the hot water return pipe 7. The cold water output pipe 6 and the hot water return pipe 7 are distributed on the inner wall of the charging pile body 1. The bottom of the charging pile body 1 is also provided with a fan 8. The air outlet of the fan 8 corresponds to the hot water return pipe 7.

[0019] This utility model discloses an AC / DC integrated charging pile, mainly comprising a charging pile body 1 and a base 2. The base 2 is a cavity structure, inside which a water tank 3, a water pump 4, and a fan 8 are installed. The charging pile body 1 contains a cooler 5, a cold water output pipe 6, and a hot water return pipe 7. The water tank 3 is used for water storage; the water pump 4 is used to input the water from the water tank into the cooler 5; the cooler 5 is used to cool the water, and then the water is transported to various parts inside the charging pile body 1 through the cold water output pipe 6, and finally transported back to the cooler 5 through the hot water return pipe 7 for cooling, forming a circulating cooling system to ensure that the internal components of the charging pile can dissipate heat quickly. In addition, a fan 8 is also installed at the bottom of the charging pile body 1, and the air outlet of the fan 8 corresponds to the hot water return pipe 7, further cooling the hot water return pipe 7 and blowing out the heat generated by the hot water return pipe 7, ensuring that the cooling effect inside the charging pile is not affected.

[0020] Specifically, water tank 3 is connected to water pump 4, and the output pipe of water pump 4 is connected to cooler 5. Water from water tank 3 is pumped into cooler 5, which cools the water and then delivers it to cold water output pipe 6. During the flow of cold water in cold water output pipe 6, the cold water absorbs heat from the charging pile body 1, causing the temperature of the cold water in cold water output pipe 6 to rise slowly. Finally, the heated hot water flows back into cooler 5 through hot water return pipe 7, thus forming a circulating cooling system. In addition, a fan 8 is installed on the side where hot water return pipe 7 is installed. The air outlet of fan 8 corresponds to hot water return pipe 7, and the heat generated by hot water return pipe 7 is blown out through the air outlet on the outside of the charging pile body to further ensure the heat dissipation effect of the charging pile.

[0021] In a preferred embodiment, refer to Figure 2The water tank 3 of the AC / DC integrated charging station has a limiting plate 9 at the bottom and a baffle 91 at the front end of the limiting plate 9. The water tank 3 has a water inlet connector 10 and a handle 11 on the outside. The water tank 3 is filled with 1 / 3 to 2 / 3 coolant, which is water or oil.

[0022] Specifically, a limiting plate 9 is installed at the bottom of the water tank 3 to facilitate its installation and maintenance. The water tank 3 and the limiting plate 9 are detachably connected by screws, and the limiting plate 9 and the base 2 are also detachably connected by screws. The water pump 4 is also mounted on the limiting plate 9. A baffle 91 is installed at the front end of the limiting plate 9 to ensure that the water tank 3 and the water pump 4 do not shift during use, ensuring good stability. Furthermore, a water inlet connector 10 and a handle 11 are installed on the outside of the water tank. The water inlet connector 10 facilitates the addition of coolant to the water tank 3, and the handle 11 facilitates the removal of the water tank 3. The coolant is mainly used to reduce the internal temperature of the charging pile, achieving a cooling effect. It should be noted from the instruction manual that the coolant in the water tank 3 should not be filled to the brim to prevent overflow. The coolant can be water or lubricating oil, and can achieve antifreeze and anti-boiling effects.

[0023] In a preferred embodiment, refer to Figure 2 The base 2 of the AC / DC integrated charging station has a switch door 21 on its outer side, and a door handle 22 on the switch door 21. An air inlet 23 is provided on the lower side and / or outer side of the base 2, and a filter screen 24 is provided on the air inlet 23.

[0024] Specifically, a switch door 21 is provided on the outside of the base 2, allowing for quick installation of the water tank 3 and rapid replenishment of coolant. When coolant needs to be added, simply open the switch door 21 and insert the water pipe into the inlet connector; the operation is simple. A handle 22 is also provided on the switch door 21 for further convenience and to ensure optimal performance. Air inlets 23 are provided on the lower and / or outer side of the base 2, allowing the fan 8 to draw outside air into the charging pile body 1 for heat dissipation. Filters 24 are installed at each air inlet 23 to ensure that the air entering the fan 8 and the charging pile body 1 is filtered, clean, and hygienic.

[0025] In a preferred embodiment, refer to Figure 1 The front side of the charging pile body 1 of the AC / DC integrated charging pile is provided with a display screen 12, a card swiping area 13, an emergency stop button 14, an indicator light 15, a lock 16, a DC charging gun placement slot 17, and an AC charging gun placement slot 18. The outer side of the charging pile body 1 is provided with a cable tray 19 and an air outlet 110.

[0026] Specifically, the display screen 12 is used to display the usage status of the charging pile and can be used for human-machine interaction control of charging and control of the heat dissipation circulation system; the card swiping area 13 is used for manual card swiping for power access and payment; the emergency stop button 14 is used to cut off power in case of emergencies such as leakage or fire; the indicator lights 15 include a power indicator light, which lights up green when powered on; a charging gun indicator light, which lights up yellow when the charging gun is charging; and a fault indicator light, which lights up red when the charging pile malfunctions; the lock 16 is used to lock the opening and closing door of the charging pile body to ensure the sealing and safety of the internal components; the DC charging gun placement slot 17 and the AC charging gun placement slot 18 are used to place the corresponding charging guns. There are two DC charging guns and two AC charging guns respectively.

[0027] In a preferred embodiment, refer to Figure 2 The air outlet pipe of the fan 8 of the AC / DC integrated charging pile is connected to the interior of the charging pile body 1. The air outlet pipe of the fan 8 corresponds to the hot water return pipe 7, which cools the hot water return pipe 7, allowing the heat generated by the hot water return pipe 7 to be quickly blown to the outside, thus achieving the effect of internal cooling.

[0028] In a preferred embodiment, refer to Figure 2 The AC / DC integrated charging pile has one or more cold water output pipes 6 and hot water return pipes 7. The cold water output pipe 6 is arranged in a U-shape around the inner wall of the charging pile body 1. By setting the cold water output pipe 6 in a U-shape and circling the inner wall of the charging pile body 1, all parts of the charging pile body 1 can use cold water circulation for heat dissipation.
