The extended external rack 111 and the liquid cooling flow rack 110 and the flow guide rack 112 provided inside the cooling box 106 are channels for the circulation of the coolant, so that the heat can be taken away and dissipated by the flow of the coolant, thereby realizing the cooling and heat dissipation of the entire device. The liquid cooling flow rack 110 and the flow guide rack 112 are connected through the connecting channel 117, and a plurality of external heat sinks 118 are fixedly installed on the outside of the connecting channel 117. By connecting the liquid cooling flow rack 110 and the flow guide rack 112 with the external connecting channel 117, the heat can be dissipated through the connecting channel 117 and the external heat sink 118 provided on the outside of the connecting channel 117 during the transmission and flow of the coolant, thereby enhancing the heat dissipation effect of the entire circulating water cooling system.

[0034] In addition, the two water tanks 113 are fixedly installed on both sides of the fixed frame 107 respectively; the access frame 114 is connected to the two water tanks 113 at the same time and is installed on one side of the fixed frame 107; the export frame 115 is connected to the two water tanks 113 at the same time, and is connected to the liquid-cooled flow frame 110, and is installed on one side of the fixed frame 107; one side of the circulating water pump 116 is connected to the access frame 114, and the other side of the circulating water pump 116 is connected to the flow guide frame 112, and the circulating water pump 116 is installed on one side of the fixed frame 107, and the driving frame 121 is slidably connected to the fixed frame 107 and is located in the fixed frame 107; the upper baffle plate 119 is connected to the access frame 114 and is fixedly installed on one side of the driving frame 121;The lower baffle plate 120 is connected to the lead-out frame 115 and fixedly mounted on one side of the driving frame 121. Two water tanks 113 are arranged in the fixed frame 107. The top and bottom of the two water tanks 113 are respectively connected to the access frame 114 and the lead-out frame 115. The access frame 114 is connected to the liquid outlet end of the circulating water pump 116 through the corresponding inlet pipe, and the lead-out frame 115 is connected to the joint of the liquid-cooled flow frame 110 through the corresponding connecting pipe. At the same time, the water inlet end of the circulating water pump 116 is connected to the flow guide frame 112 through the corresponding conduit. The access frame 114 and the lead-out frame 115 are both provided with two corresponding interfaces to facilitate communication with the two water tanks 113. At the same time, the access frame 114 and the lead-out frame 115 are both provided with an upper shielding plate 119 or a lower shielding plate 120 at the interface connected with the two water tanks 113.

In this way, the connecting cable 104 in the working state can be cooled down by the flow of the coolant in the corresponding guide rack and the setting of the cooling box 106 and the extended external rack 111. At the same time, when the coolant continues to flow and absorb heat, once the operation time is longer than the whole The coolant inside the circulation system will begin to heat up. At this time, the upper baffle plate 119 and the lower baffle plate 120 provided on the access frame 114 and the output frame 115 are driven by the control component, so that the low-temperature coolant inside the other water tank 113 can enter the corresponding cooling circulation system. When the coolant inside the other water tank 113 is circulated and cooled, the coolant with a higher temperature before can be dissipated accordingly, so that the same replacement can be performed later when the temperature of the coolant inside the other water tank 113 begins to rise. The use of an external liquid cooling device can reduce the size of the charging terminal, greatly reduce noise, and extend its service life. In addition, the liquid cooling device can simultaneously cool the liquid cooling gun line and the terminal input cable, thereby reducing the outer diameter of the input cable and the amount of cable used, thereby minimizing the cost of equipment use.

Then, when the driving motor 205 drives the driving gear 204 in reverse to rotate, the connection relationship between the two water tanks 113 and the circulation system can be converted. The driving motor 205 is connected to the adapter controller 202 through a corresponding operating circuit. When the adapter controller 202 receives the coolant temperature in the corresponding water tank 113 sensed by the temperature sensor 201 that is too high, the driving motor 205 can be controlled to drive the driving gear 204 in the corresponding direction, so as to block the water tank 113 with too high temperature, and then connect the other water tank 113 to the corresponding cooling circulation system.

[0040] When using a single-gun liquid-cooled charging terminal and charging method of the present embodiment, the temperature sensor 201 provided on the sides of the two water tanks 113 can be used to monitor the temperature of the coolant in the corresponding water tank 113. When the detected coolant temperature is higher than the set value and the setting range, the adapter controller 202 can drive the drive motor 205 through the signal transmitted by the temperature sensor 201, and then drive the drive frame 121 and the corresponding baffle plate provided on the drive frame 121 through the drive motor 205 in cooperation with the drive gear 204 and the connecting rack 203, so as to complete the conversion of the two water tanks 113, so that in the actual operation process, the connection conversion of the two water tanks 113 can be automatically judged and completed according to the actual situation, which greatly enhances the practicality of the entire device.

[0044] When using a single-gun liquid-cooled charging terminal and charging method of the present embodiment, the heat dissipation fan 302 can be used in conjunction with the barrier filter plate 301 to accelerate the airflow conversion inside the entire pile body, thereby achieving rapid and stable heat dissipation of the pile body and the internal system as a whole. In addition, by arranging a plurality of heat dissipation wing plates 303 on the outside of the water tank 113 in conjunction with the heat dissipation fan 302, the coolant inside the water tank 113 can be dissipated and cooled more quickly and stably, thereby ensuring the stable operation of the entire circulation system and greatly enhancing the practicality of the entire device.
