DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a liquid-cooled charging pile. Figure 1-Figure 2As shown, it includes a charging pile 1, and a charging port 2 is provided on one side outer wall of the charging pile 1 for installing a charging head for charging. A heat sink 3 can be connected to the back of the charging pile 1 by screws. A movable groove 4 is provided in the middle of the surface of the heat sink 3. A movable plate 5 is detachably provided inside the movable groove 4. A cooling fan 6 is installed at the center of the movable plate 5. The cooling fan 6 plays a role of auxiliary heat dissipation and is used to accelerate the heat flow of internal liquid cooling.

[0021] Combination Figure 3-Figure 4 As shown, a heat sink 13 is fixedly installed inside the heat sink 3, and the heat sink 13 fits the inner wall of the charging pile 1 to improve the heat transfer efficiency, and a group of connecting pipes 14 are equidistantly distributed at both ends of the heat sink 13, and one end of the connecting pipe 14 is fixedly connected to a heat sink 8, and the heat sink 8 is distributed at both ends of the heat sink 3 to improve the heat dissipation efficiency, and a liquid cooling pipe 7 is provided at one end of the heat sink 8 away from the connecting pipe 14, and the liquid cooling pipe 7 is set in a U-shape, which expands the overall liquid cooling area;

[0022] In addition, a plurality of shunt pipes 15 are evenly distributed inside the heat dissipation fin 8 away from one end of the connecting pipe 14. One end of the shunt pipe 15 extends into the connecting pipe 14, and the other end of the shunt pipe 15 is fixed to the inner wall of the liquid cooling pipe 7, so that the circulation of the coolant can be realized. One end of the liquid cooling pipe 7 is an integrated structure with a connecting pipe head 9, which is connected to an external coolant pump through the connecting pipe head 9.

[0023] In addition, connecting rods 10 are symmetrically fixed on the surface of the heat dissipation fins 8, and a threaded tube 11 is rotatably installed on the outside of the connecting rod 10. The internal thread of the threaded tube 11 away from one end of the connecting rod 10 is connected with a matching threaded rod 12. One end of the threaded rod 12 is movably connected to the inner wall of the movable plate 5. By rotating the threaded tube 11, the movable plate 5 can be pushed and pulled to move in the movable groove 4 through the threaded rod 12, thereby facilitating the adjustment of the distance between the heat dissipation fan 6 and the liquid cooling pipe 7.

[0024] The implementation principle of a liquid-cooled charging pile in the embodiment of the present application is as follows: when in use, the connecting pipe head 9 is connected to an external coolant pump, so that the coolant can be pumped into the liquid cooling pipe 7, and is diverted to the inside of the heat dissipation fins 8 through multiple shunt pipes 15, and then transported to the heat sink 13 through the connecting pipe 14. Since the heat sink 13 is in contact with the inner wall of the charging pile 1, it can quickly absorb heat and play a good cooling role. At the same time, the heat dissipation fins 8 can increase the heat dissipation area and improve the heat exchange efficiency, thereby promoting heat energy transfer. Through the heat dissipation process of the circulation of the coolant, an efficient, low-noise and safe charging experience is achieved. It has higher heat dissipation efficiency and can effectively reduce the internal temperature of the charging pile 1 during high-power charging, thereby improving the charging efficiency. At the same time, the threaded barrel 11 can be adjusted to drive the threaded rod 12 to contract on its inner wall, thereby pushing the movable plate 5 to move in the movable groove 4, which is convenient for adjusting the distance between the heat dissipation fan 6 and the liquid cooling pipe 7. The operation of the liquid cooling pipe 7 can accelerate the internal heat circulation and further improve the heat dissipation effect.
