[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Please refer to the appendix. Figures 1-6The present invention provides a liquid cooling device for supercharging piles, including a charging pile shell 1, a controller 2 fixed on the upper front side of the charging pile shell 1, a partition 3 horizontally fixed on the lower inside of the charging pile shell 1, and a liquid cooling component and an air cooling component. The liquid cooling component is fixedly installed in the lower inside of the charging pile shell 1, and the air cooling component is fixedly installed in the upper inside of the charging pile shell 1. Both the liquid cooling component and the air cooling component are electrically connected to the controller 2. The liquid cooling assembly includes an insulation box 4, the bottom of which is fixed to the bottom of the inner wall of the charging pile housing 1. A cooling water tank 5 is fixed inside the insulation box 4. The insulation box 4 effectively prevents the rapid loss of cooling water in the cooling water tank 5. A cooler 6 is also fixed to the bottom of the inner wall of the insulation box 4. It should be noted that the cooler is a miniaturized temperature control device based on the semiconductor thermoelectric effect. It is a device that achieves heat transfer through DC power control. The cooler mainly relies on the thermoelectric effect (Peltier effect) to achieve cooling, that is, when current passes through a semiconductor material, heat is transferred from one end to the other, thus forming a temperature difference. This technology does not require mechanical compression components and has the characteristics of small size, no noise, and fast response. It is widely sold on the market. The cooler 6 is electrically connected to the controller 2. A cooling plate 7 is fixed to the output end of the cooler 6. The cooling plate 7 is fixed inside the cooling water tank 5, that is, on the cooling plate 7 of the cooler 6. Under the cooling effect, it can be used to cool the cooling water added to the cooling water tank 5, thereby ensuring that the cooling water still has a good liquid cooling effect after circulation. A liquid level sensor 8 is fixed at the bottom of the inner wall of the cooling water tank 5 and is electrically connected to the controller 2. A first temperature sensor 9 is fixed on the side of the inner wall of the cooling water tank 5 and is electrically connected to the controller 2. Specifically, under the action of the liquid level sensor 8, it can be used to monitor the cooling water level in the cooling water tank 5 in real time. Under the action of the first temperature sensor 9, it can be used to monitor the cooling water temperature in the cooling water tank 5 in real time. The operator can set the required cooling water temperature through the controller 2. When the cooling water circulation temperature rises, the first temperature sensor 9 detects that the cooling water temperature exceeds the set temperature, and the controller 2 controls the refrigerator 6 to run to cool the cooling water. With the use of the insulation box 4, the cooling effect of the cooling water is guaranteed. A water pump 10 is fixed to the bottom of the inner wall of the insulation box 4. The water pump 10 is electrically connected to the controller 2. The input end of the water pump 10 is fixedly connected to a water suction pipe 11, which is fixedly connected to the bottom side of the cooling water tank 5. The output end of the water suction pipe 11 is fixedly connected to a water delivery pipe 12. That is, when the controller 2 controls the water pump 10 to run, the cooling water in the cooling water tank 5 can be drawn out through the water suction pipe 11 and then delivered through the water delivery pipe 12. The top end of the water delivery pipe 12 passes vertically through the partition 3, and the top end of the water delivery pipe 12 is fixedly connected to a first serpentine cooling pipe 13. The first serpentine cooling pipe 13 is located inside the front side of the charging pile shell 1. The top end of the first serpentine cooling pipe 13 is fixedly connected to a second serpentine cooling pipe 14, which is located inside the upper part of the charging pile shell 1. The end of the second serpentine cooling pipe 14 is fixedly connected to... There is a third serpentine cooling pipe 15, which is located inside the rear side of the charging pile shell 1. The bottom end of the third serpentine cooling pipe 15 is fixedly connected to a return water pipe 16. The bottom end of the return water pipe 16 passes through the partition 3 and is located directly above the cooling water tank 5. Specifically, when the water pump 10 is running, it can draw out the cooling water in the cooling water tank 5, and then pump it into the first serpentine cooling pipe 13 through the water supply pipe 12. Then it enters the second serpentine cooling pipe 14 through the first serpentine cooling pipe 13, and then enters the third serpentine cooling pipe 15 through the second serpentine cooling pipe 14. Finally, it circulates back into the cooling water tank 5 through the return water pipe 16, so as to effectively perform liquid cooling operations on the front, back and top of the charging pile shell 1, thus effectively realizing the function of liquid cooling of the supercharging pile. A water inlet pipe 17 is fixedly connected to the top of the side of the cooling water tank 5. The rear end of the water inlet pipe 17 passes through the rear end of the insulation box 4 and the rear end of the charging pile shell 1. A sealing plug 18 is threaded to the rear end of the water inlet pipe 17. A glass tube level gauge 19 is fixedly connected to the side of the cooling water tank 5. The glass tube level gauge 19 passes through the side of the insulation box 4 and the side of the charging pile shell 1. A drain pipe 20 is also fixedly connected to the side of the cooling water tank 5. The drain pipe 20 passes through the side of the insulation box 4 and the side of the charging pile shell 1. A shut-off valve 21 is fixed to the body of the drain pipe 20. Specifically, the operator can switch the sealing plug 18 and then add the required cooling water to the cooling water tank 5 through the water inlet pipe 17. The operator can also switch the shut-off valve 24 to control the discharge or replacement of the cooling water. Under the action of the glass tube level gauge 19, the cooling water level in the cooling water tank 5 can be monitored in real time again to avoid the cooling water in the cooling water tank 5 being unviewable when the level sensor 8 fails. The air-cooled assembly includes several fan housings 22, which are symmetrically fixed to the top of the charging pile housing 1. Each fan housing 22 has a dust filter 23 fixed to its top. Motor brackets 24 are horizontally fixed to the inner side of each fan housing 23, and motors 25 are fixed to the middle of each motor bracket 24. Each motor 25 is electrically connected to a controller 2. Fan blades 26 are fixed to the bottom of the output shaft of each motor 25. Several air inlets 27 are evenly distributed on the top of the charging pile housing 1, located directly below each fan housing 22. Heat dissipation grilles 28 are fixed to the sides and rear of the charging pile housing 1. Specifically… When the controller 2 controls the operation of several motors 25, the running motors 25 can drive the corresponding fan blades 26 to rotate at high speed, thereby generating wind power. The wind power is blown into the charging pile shell 1 through several air inlets 27, which can cool the supercharging pile. Then it is discharged through the heat dissipation grille 28. When the wind power is blown in, it can first exchange heat through the second serpentine cooling pipe 14, so that the wind power can be cooled to a certain extent. That is, the liquid cooling structure can also cool the wind power, ensuring continuous cold air. Thus, it can achieve dual cooling function, which can well meet the cooling needs of the supercharging pile. It can also recycle cooling water to achieve energy saving. A second temperature sensor 29 is fixed at the top center of the partition 3. The second temperature sensor 29 is electrically connected to the controller 2. Specifically, the second temperature sensor 29 can monitor the internal temperature of the charging pile shell 1 in real time and provide feedback to the controller 2 in real time. Then, the controller 2 can determine whether to simultaneously turn on the water pump 10 for liquid cooling and turn on several motors 25 for air cooling, or only turn on the water pump 10 for liquid cooling or only turn on the motors 25 for air cooling, based on the actual internal temperature of the charging pile shell 1 and the temperature required by the operator through the controller 2. This allows for intelligent use based on the weather temperature, such as summer or winter, thereby achieving a good energy-saving effect.

[0022] The usage process of this invention is as follows: During use, the operator can set the required temperature inside the charging pile shell 1 and the required temperature of the cooling water through the controller 2. Then, the controller 2 can control the operation of the cooler 6, the water pump 10 and several motors 25 through the first temperature sensor 9 and the second temperature sensor 29. When the temperature of the cooling water circulation rises, the first temperature sensor 9 detects that the cooling water temperature exceeds the set temperature, and the controller 2 controls the cooler 6 to run to cool the cooling water. With the use of the insulation box 4, the cooling effect of the cooling water is guaranteed. When the water pump 10 is running, it can draw out the cooling water in the cooling water tank 5, and then pump it into the first serpentine cooling pipe 13 through the water supply pipe 12. Then it enters the second serpentine cooling pipe 14 through the first serpentine cooling pipe 13, and then enters the third serpentine cooling pipe 15 through the second serpentine cooling pipe 14. Finally, it circulates back into the cooling water tank 5 through the return water pipe 16. This can effectively perform liquid cooling operations on the front, back and top of the charging pile shell 1, thus effectively realizing the function of liquid cooling for the supercharging pile. When several motors 25 are running, they can drive the corresponding fan blades 26 to rotate at high speed, thereby generating wind. The wind is blown into the charging pile housing 1 through several air inlets 27, which can cool the supercharging pile. The wind is then discharged through the heat dissipation grille 28. When the wind blows in, it can first exchange heat through the second serpentine cooling pipe 14, so that the wind can be cooled to a certain extent. That is, the liquid cooling structure can also cool the wind, ensuring continuous cold air. Thus, it can achieve dual cooling function, which can well meet the cooling needs of the supercharging pile. It can also recycle cooling water to achieve energy saving. Furthermore, the second temperature sensor 29 can monitor the internal temperature of the charging pile casing 1 in real time and provide feedback to the controller 2 in real time. The controller 2 can then determine, based on the actual internal temperature of the charging pile casing 1 and the required temperature set by the operator, whether to simultaneously turn on the water pump 10 for liquid cooling and several motors 25 for air cooling, or to turn on only the water pump 10 for liquid cooling or only the motors 25 for air cooling. This allows for intelligent use based on weather temperature, such as summer or winter, thereby achieving excellent energy-saving effects.
