Abstract
Description
Technical Field
[0001] This utility model belongs to the field of charging pile technology, specifically relating to an immersion liquid-cooled charging pile. Background Technology
[0002] A charging station is a device that provides charging services for electric vehicles. Its function is similar to a gas pump at a gas station, supplying electrical energy to electric vehicles so that they can store enough electricity to power their operation.
[0003] Charging modules in charging stations generate a significant amount of heat during operation. If this heat is not dissipated promptly, it can lead to overheating, damaging internal electronic components and affecting the charging station's normal operation and lifespan. A cooling system effectively reduces the charging station's operating temperature, keeping it within its optimal operating range, thereby improving charging efficiency and speed. This is especially crucial for high-power charging stations, as it ensures stability and safety under prolonged, high-load operation, reducing safety hazards caused by overheating. Furthermore, the sealed environment of the liquid cooling system enhances protection against external environmental corrosion.
[0004] However, most charging modules in the current technology contain a protective aluminum shell for protection. While this does enhance the protection, it also isolates the heat dissipation to some extent. Therefore, it is often necessary to remove and replace the module or disassemble it for maintenance, which is a waste of manpower. If it is not maintained for a long time, the charging effect will be weakened. Therefore, it is necessary to optimize the heat dissipation of the charging module. Utility Model Content
[0005] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide an immersive liquid-cooled charging pile.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0007] An immersion liquid-cooled charging pile includes a cabinet, the cabinet being divided into a lower chamber and an upper chamber. A liquid storage tank is installed at the bottom of the lower chamber, and multiple charging modules are installed inside the liquid storage tank. The multiple charging modules are electrically connected in series and parallel. The liquid storage tank is equipped with a liquid discharge mechanism and a liquid inlet mechanism. A main control mechanism is installed inside the lower chamber on the upper side of the liquid storage tank.
[0008] A radiator is installed in the upper chamber. The input end of the radiator is connected to the output end of the liquid outlet mechanism by a pipeline. The output end of the radiator is connected to the input end of the liquid inlet mechanism by a pipeline. A fixing plate is installed in the upper chamber. A compressor is installed on the upper side of the fixing plate. A fan is installed on the radiator. The fan is located between the radiator and the compressor.
[0009] The cabinet is equipped with an inlet filter and an outlet filter at the front and rear positions of the fan, respectively.
[0010] Furthermore, the top of the liquid storage tank is equipped with a cover plate, and a rubber sealing ring is installed between the cover plate and the liquid storage tank. This design not only protects the internal liquid from dust but also prevents the liquid from atomizing and evaporating, and also prevents external temperature from interfering with the internal liquid stability.
[0011] Furthermore, the liquid outlet mechanism is equipped with a charger liquid cooling pipe interface. This design is used to connect the liquid cooling pipe of the liquid-cooled charging gun to realize the circulation of coolant.
[0012] Furthermore, the main control mechanism includes an electricity meter, a power distribution unit, an AC contactor, a circuit breaker, an emergency stop button, and copper busbars. This design ensures the normal operation of the charging pile.
[0013] Furthermore, the air inlet filter and the air outlet filter are composed of a honeycomb-shaped dustproof outer layer and a louvered inner layer. This design provides good dust filtration and prevention.
[0014] The beneficial effects of using this utility model are as follows:
[0015] This invention directly integrates the liquid-cooled equipment into the liquid-cooled charger of the charging pile, and then directly immerses the charging module assembly (with the outer protective aluminum shell removed) completely in the cooling and cleaning liquid. This greatly increases the heat exchange efficiency and reduces the complicated operation of disassembling the charging module inside the charger for independent cleaning and then reinstalling it into the charger. The immersion liquid-cooled charging pile can maintain high-efficiency output for a long time, avoiding problems such as overheating or dust accumulation of the charging module, and also facilitates the maintenance and replacement of the charging module.

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides an immersion liquid-cooled charging pile, including a cabinet 1. The cabinet 1 is divided into a lower chamber 2 and an upper chamber 3. A liquid storage tank 4 is installed at the bottom of the lower chamber 2. Multiple charging modules 5 are installed inside the liquid storage tank 4. The multiple charging modules 5 are electrically connected in series and parallel. The liquid storage tank 4 is equipped with a liquid discharge mechanism 6 and a liquid inlet mechanism 7. A main control mechanism 8 is installed on the upper side of the liquid storage tank 4 inside the lower chamber 2.
[0026] A radiator 9 is installed in the upper chamber 3. The input end of the radiator 9 is connected to the output end of the liquid outlet mechanism 6 by a pipeline. The output end of the radiator 9 is connected to the input end of the liquid inlet mechanism 7 by a pipeline. A fixing plate 10 is installed in the upper chamber 3. A compressor 11 is installed on the upper side of the fixing plate 10. A fan 12 is installed on the radiator 9. The fan 12 is located between the radiator 9 and the compressor 11.
[0027] The cabinet 1 has an inlet filter 13 and an outlet filter 14 installed at the front and rear positions of the fan 12, respectively.
[0028] In this implementation case, when using an immersion liquid-cooled charging pile, when the main control mechanism 8 receives a signal that the temperature of the cleaning fluid in the storage tank 4 exceeds the set temperature, it starts the compressor 11. The cleaning fluid in the storage tank 4, which is heated and floating upward due to the operation of the charging module, is output to the radiator 9 through the upper liquid outlet mechanism 6 for internal heat exchange. Then, the cooled cleaning fluid is returned to the storage tank 4 through the lower liquid inlet mechanism 7. The cycle repeats until the monitored temperature is lower than the set temperature, at which point it is turned off.
[0029] In summary, while achieving liquid cooling, the charging module 5 is located inside the liquid storage tank 4, which protects the charging module 5. Therefore, the charging module 5 no longer needs a protective aluminum shell, which facilitates subsequent replacement and maintenance.
[0030] The preferred liquid storage tank 4 is equipped with a cover plate 41 on top, and a rubber sealing ring 42 is installed between the cover plate 41 and the liquid storage tank 4. This design not only protects the internal liquid from dust, but also prevents the liquid from atomizing and evaporating. It also prevents external temperature from interfering with the internal liquid stability. In fact, the sealing protection structure of the liquid storage tank 4 can also be considered according to the specific situation.
[0031] Preferably, the liquid outlet mechanism 6 is equipped with a charger liquid cooling pipe interface 61. This design is used to connect the liquid cooling pipe of the liquid cooling charging gun to realize the circulation of coolant. In fact, the structure of the liquid outlet mechanism 6 can also be considered according to specific circumstances.
[0032] The preferred main control mechanism 8 includes an electricity meter 81, a power distribution unit 82, an AC contactor 83, a circuit breaker 84, an emergency stop button 85, and a copper busbar 86. This design ensures the normal operation of the charging pile. In fact, the structural units included in the main control mechanism 8 can also be considered according to specific circumstances.
[0033] The preferred design of the inlet filter 13 and the outlet filter 14 consists of a honeycomb-shaped dustproof outer layer and a louvered inner layer. This design provides good dust filtration. In fact, the structure of the inlet filter 13 and the outlet filter 14 can also be considered according to specific circumstances.
[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
