Abstract
Description
Technical Field

[0002] With the rapid development of the electric vehicle market, the performance and reliability of charging piles as important facilities for energy supply are crucial. Since charging piles generate a lot of heat during operation, especially charging modules and power electronic devices, effective heat dissipation design is of great significance to ensure the stable operation of charging piles and extend their service life.
[0003] At present, most charging piles use liquid cooling to dissipate heat. Liquid cooling is a process in which coolant circulates in the charging module to take away the heat and discharge it to the outside. However, using only one heat dissipation structure for heat dissipation will result in poor heat dissipation effect. When liquid cooling cannot meet the heat dissipation needs of the charging pile, it will easily cause damage to the charging pile and even the risk of fire, thereby reducing the safety of use.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:
[0019] A liquid-cooled charging device for a charging station comprises a charging pile 1, a cooling unit 2 installed inside the charging pile 1 and an air cooler 3 fixed on the top of the charging pile 1. A working chamber 4 is provided inside the charging pile 1, the cooling unit 2 is installed in the working chamber 4, a temperature sensor 5 is installed on the top of the working chamber 4, a cooling chamber 6 is formed between the outside and an outer shell of the charging pile 1, a cold air nozzle 7 is connected to the cooling chamber 6, a plurality of cold air inlets are provided on the outer surface of the working chamber 4, a cooling chamber 8 separated by a partition is provided below, a cooling mechanism is installed inside the cooling chamber 8, and a plurality of through holes are provided on the partition.
[0020] When the charging pile 1 is in normal use, heat is dissipated through the cooling unit 2 (which is a liquid-cooled charging module in the prior art). During operation, the internal temperature is monitored in real time by the temperature sensor 5. When the internal temperature still rises after liquid cooling, a signal is generated to start the air cooling mechanism to increase the intensity of heat dissipation through air cooling. If the temperature continues to rise, a signal is generated again to start the air cooler 3. The cold air enters the cooling chamber 6 through the cold air nozzle 7, and then enters the working chamber 4 through a number of cold air inlets for cooling and heat dissipation, thereby increasing the contact area and improving the heat dissipation effect.
[0021] A plurality of heat dissipation channels 9 are provided between the outside of the working chamber 4 and the outer shell of the charging pile 1 , through which ventilation and heat dissipation are performed, and at the same time, the heat dissipation channels 9 can cooperate with the air cooling mechanism to speed up the exchange of air inside and outside.
[0022] The air cooling mechanism includes a mounting frame fixed inside the air cooling chamber 8 , a servo motor arranged on the mounting frame, and a fan 10 driven by the servo motor. A control box 11 is installed on the inner wall of the air cooling chamber 8 .
[0023] A sealed door 12 is installed on the outside of the charging pile 1 , and a heat dissipation grille is installed below the sealed door 12 .
[0024] An alarm is installed on the outside of the charging pile 1 and is turned on by the control box 11 .
[0025] The servo motor drives the fan 10 to rotate, thereby speeding up the air circulation. A controller is installed inside the control box 11 to control the servo motor, the air cooler 3 and the alarm. When the air cooler 3 is turned on, the alarm will be turned on at the same time to prompt the staff to detect the reason for the high temperature.
