[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a charging pile liquid cooling device, comprising: a charging pile mechanism 1, comprising a charging pile body 11, and a display screen 12 arranged on the charging pile body 11; a charging gun mechanism 2, comprising a charging gun assembly 21 installed on the outside of the charging pile body 11, and a circuit board assembly 22 arranged inside the charging pile body 11, wherein the charging gun assembly 21 and the circuit board assembly 22 are connected to each other; a liquid cooling mechanism 3, comprising a liquid cooling box assembly 31 arranged inside the charging pile body 11, a cooling pipe assembly 32 arranged outside the liquid cooling box assembly 31, and a liquid cooling plate assembly 33 installed outside the cooling pipe assembly 32;

[0022] Among them, when heat dissipation is required, the cooling pipe assembly 32 can dissipate heat for the charging gun assembly 21 by controlling the operation of the liquid cooling box assembly 31, thereby preventing the charging gun assembly 21 from being overheated and damaged. At the same time, when the liquid flows through the cooling pipe assembly 32, it will also drive the liquid cooling plate assembly 33 to work. The operation of the liquid cooling plate assembly 33 can cool down the circuit board assembly 22, thereby preventing the circuit board assembly 22 from being overheated and damaged.

[0023] Specifically, the liquid cooling box assembly 31 includes a liquid cooling box body 311, and a guide plate 312 is fixedly connected to the interior of the liquid cooling box body 311; the cooling pipe assembly 32 includes a liquid pump 321, one end of the liquid pump 321 is fixedly connected to a filter pipe 322, and the other end of the liquid pump 321 is fixedly connected to a liquid cooling pipe 323.

[0024] Specifically, the liquid cooling plate assembly 33 includes a liquid cooling plate body 331 , and a liquid inlet pipe 332 and a liquid outlet pipe 333 are disposed on one side of the liquid cooling plate body 331 .

[0025] Specifically, the liquid inlet pipe 332 and a position on the liquid cooling pipe 323 close to the liquid pump 321 are connected to each other, and the liquid outlet pipe 333 and a position on the liquid cooling pipe 323 far from the liquid pump 321 are connected to each other.

[0026] As can be seen from the above, by controlling the operation of the liquid pump 321, the filter tube 322 can extract the coolant inside the liquid cooling box body 311, and the extracted coolant will pass through the liquid cooling tube 323 and return to the liquid cooling box body 311 again and be guided by the guide plate 312, so that the coolant is gradually mixed with the coolant in the liquid cooling box body 311. When the coolant passes through the liquid cooling tube 323, the interior of the charging gun assembly 21 is dissipated. When the coolant passes through the liquid cooling tube 323, it will also flow into the liquid inlet pipe 332, and after passing through the liquid cooling plate body 331, it will return to the liquid cooling tube 323 again through the liquid outlet pipe 333. The coolant passing through the liquid cooling plate body 331 will dissipate heat for the circuit board assembly 22.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the charging gun assembly 21 includes a rubber tube 211, the end of which is fixedly connected to a charging gun body 212; the circuit board assembly 22 includes a cable 221, one end of which is fixedly connected to a circuit board body 222.

[0028] Specifically, the rubber tube 211 is fixedly connected to the outside of the charging pile body 11, the charging gun body 212 can be embedded in the outside of the charging pile body 11, the circuit board body 222 is fixedly installed on the liquid cooling plate body 331, the cable 221 passes through the rubber tube 211 and is interconnected with the charging gun body 212, and the liquid cooling tube 323 is located inside the rubber tube 211.

[0029] As can be seen from the above, the liquid cooling tube 323 is located inside the rubber tube 211. When coolant flows inside the liquid cooling tube 323, the rubber tube 211 will be quickly cooled down, thereby avoiding overheating of the rubber tube 211 during charging. The circuit board body 222 is fixedly installed on the liquid cooling plate body 331. When coolant flows inside the liquid cooling plate body 331, the circuit board body 222 will be quickly cooled down, thereby avoiding overheating of the circuit board body 222 during charging.
