[0018] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 and attached Figure 2As shown, an improved liquid-cooled charging pile includes a charging pile 1. The front of the charging pile 1 has hinged doors on both the upper and lower sides. The lower door is designed to be open to dissipate heat. A charging gun 11 is installed on one side of the charging pile 1. An installation frame 12 is fixedly installed on the upper side of the inside of the charging pile 1. A DC charging module 13, an input circuit breaker 14, an AC contactor 15, and a charging control module 16 are installed on the front of the installation frame 12. A liquid cooling plate 2 is installed on the rear side of the installation frame 12. The liquid cooling plate 2 is fixedly installed on the charging pile 1. A condenser 3 and a coolant storage tank 4 are arranged side by side on the lower side of the inside of the charging pile 1. A bidirectional filter tube assembly 5 is also installed inside the charging pile 1.
[0019] In this implementation plan, in conjunction with the appendix Figure 3 and attached Figure 4 As shown, the bidirectional filter tube assembly 5 includes an inlet pipe 51 and an outlet pipe 52. Inlet valves 54 are installed at the two outlets of the inlet pipe 51, and each inlet valve 54 is connected to a filter tube 53 at its other end. A threaded cap 57 is threaded to the other end of the filter tube 53. An outlet valve 55 is integrated into the upper end of the filter tube 53 and connected to one of the two outlet valves 55 at the two inlets of the outlet pipe 52. A filter element is fixedly installed on the left side of the threaded cap 57. The filter cartridge 58 is a metal mesh filter cartridge. A rubber ring 56 is installed inside the end of the filter tube 53 near the liquid inlet valve 54. The coolant enters the two filter tubes 53 through the liquid inlet pipe 51. The coolant filtered by the filter cartridge 58 enters the liquid cooling plate 2 through the liquid outlet pipe 52 to filter the coolant. When cleaning the filter cartridge 58, close the liquid inlet valve 54 and the liquid outlet valve 55 corresponding to the filter cartridge 58, rotate and open the threaded cover 57 to remove the filter cartridge 58. At this time, the other filter cartridge 58 can continue to filter.

[0021] In this embodiment, specifically, the outlet of the liquid outlet pipe 52 is connected to the inlet of the liquid cooling plate 2.
[0022] In this embodiment, specifically, the outlet of the liquid cooling plate 2 is connected to the inlet pipe of the coolant storage tank 4.
[0023] In this embodiment, specifically, the outlet end of the coolant storage tank 4 is connected to the inlet end pipe of the condenser 3.

[0025] Working principle
[0026] In this utility model, the DC charging module 13, the input circuit breaker 14, the AC contactor 15, and the charging gun 11 are all electrically connected to the charging control module 16, realizing the function of charging the device that needs to be charged through the charging gun 11. The liquid cooling plate 2 cools the inside of the charging pile 1, realizing the function of liquid cooling heat dissipation. The coolant in the coolant storage tank 4 enters the condenser 3 for cooling. The cooled coolant is filtered through the bidirectional filter tube assembly 5 and then enters the liquid cooling plate 2 to exchange heat with the internal environment of the charging pile 1, thus achieving liquid cooling heat dissipation inside the charging pile 1.
