[0030] In the embodiment: water tank 2 is used as the storage unit of coolant, is connected with charging module 1 by pipeline, forms a closed loop coolant circulation loop;Water pump 3 is responsible for driving coolant to circulate in pipeline, removes heat from charging module 1, and exchanges heat with external environment through heat exchanger 4, realizes effective heat dissipation;At the same time, the speed and operating state of fan are controlled using intelligent control system, to achieve the best heat dissipation effect;At the same time, in order to monitor the state of coolant in real time, pressure transmitter 6, water supply temperature transmitter 7 and flow transmitter 8 are installed on circulation pipeline, the data collected by these sensors are transmitted to cooling system controller 15, which is comprehensively analyzed by controller and makes corresponding adjustment decision, to ensure that charging pile can still maintain stable and efficient heat dissipation performance under high load operation;Not only improve the heat dissipation efficiency, but also realize intelligent management, provide strong technical support for fast charging of electric vehicles;

[0031] Liquid circulation system selects high-efficiency, low-noise water pump 3 and corrosion-resistant water tank 2, and the coolant is delivered to the inside of liquid cooling charging pile through pipeline, the pipeline is made of high-temperature-resistant and corrosion-resistant material to ensure safety and reliability;Heat exchanger 4 and cooling fan 5 are selected to dissipate heat from the hot liquid in the circulation through heat exchanger 4;Cooling system controller 15 adopts high-performance single-chip microcomputer controller, has multiple protection functions and fault diagnosis functions, is connected with the signals of key components in circulation cooling assembly and heat dissipation assembly, sets corresponding control strategy, and supports multiple communication protocols and interfaces, to facilitate linkage control with other devices.

[0032] As a preferred embodiment, ball valves 9 are arranged between water pump 3 and charging module 1 and between charging module 1 and heat exchanger 4, and filter 10 is installed on the coolant circulation pipeline between charging module 1 and heat exchanger 4.

[0033] In this embodiment: by adding ball valves 9 on the cooling liquid circulation pipelines between the water pump 3 and the charging module 1 and between the charging module 1 and the heat exchanger 4, not only the flexibility and controllability of the system are enhanced, so that the operating personnel can quickly cut off or adjust the flow path of the cooling liquid when necessary, thereby effectively dealing with various emergency situations or maintenance work, but also more safety is provided for the daily operation of the system; the filter 10 installed on the pipeline between the charging module 1 and the heat exchanger 4 can intercept and remove impurities and particulate matter in the cooling liquid, ensuring the cleanliness of the cooling liquid during circulation, thereby protecting the key components in the system from wear and blockage, and prolonging the service life of the entire heat dissipation cooling system.

[0034] As a preferred embodiment, on the basis of the above-mentioned mode, further, a backwater temperature transmitter 11 is installed on the cooling liquid circulation pipeline between the charging module 1 and the heat exchanger 4.

[0035] In this embodiment: by adding the backwater temperature transmitter 11 on the cooling liquid circulation pipeline between the charging module 1 and the heat exchanger 4, the system can more comprehensively monitor the temperature change of the cooling liquid during circulation, not only paying attention to the supply water temperature, but also accurately mastering the backwater temperature, thereby realizing real-time evaluation of the heat exchange efficiency of the cooling liquid; the backwater temperature transmitter 11 accurately transmits the collected temperature data to the cooling system controller 15, providing more abundant decision basis for the controller, so that it can more accurately adjust the water pump 3 speed, heat dissipation fan 5 working state, etc., to achieve the best heat dissipation effect and energy efficiency ratio. This improvement not only improves the intelligent level of the system, but also further ensures the stable operation of the liquid-cooled charging pile under high temperature and high load conditions.

When the cooling liquid level is too low and is about to reach the minimum working liquid level of the water pump 3, the liquid level switch 12 will immediately issue an alarm to the cooling system controller 15 and trigger the corresponding protection measures, such as suspending the operation of the water pump 3, to prevent equipment damage due to lack of liquid. Not only the self-protection ability of the system is enhanced, but also the risk of equipment failure due to operation errors or accidents is greatly reduced, thereby ensuring the long-term stable operation and safety of the liquid-cooled charging pile heat dissipation cooling system.

[0038] As a preferred embodiment, on the basis of the above-mentioned mode, further, an exhaust valve 13 is arranged at the top of the water tank 2 and can automatically separate steam and water and exhaust, reducing liquid leakage.

[0039] In the present embodiment: the exhaust valve 13 is arranged at the top of the water tank 2, which can automatically separate steam and water and effectively discharge the gas in the system. During the cooling liquid circulation process, due to temperature changes and pressure differences, bubbles or air may be generated in the system. If these gases are not discharged in time, not only will they affect the flow efficiency and heat exchange performance of the cooling liquid, but they may also cause unnecessary pressure and damage to the system. The introduction of the exhaust valve 13 can continuously monitor and exclude the gas in the system, effectively reduce the risk of liquid leakage, and at the same time maintain the purity of the cooling liquid and the stability of the circulation system, thereby further improving the overall performance and reliability of the liquid-cooled charging pile cooling system.

[0040] As a preferred embodiment, on the basis of the above-mentioned mode, further, the bottom of the water tank 2 is provided with a drain valve 14, which facilitates the reservation of sufficient space for maintenance, maintenance and maintenance.

[0041] In the present embodiment: by arranging the drain valve 14 at the bottom of the water tank 2, the operator can easily discharge the cooling liquid from the system when the system needs to be overhauled, maintained or maintained, which provides great convenience for subsequent maintenance work. By opening the drain valve 14, the cooling liquid in the water tank 2 and the cooling circulation pipeline can be quickly emptied, reserving sufficient space for entering the water tank 2 or the pipeline system for inspection, cleaning or replacement of components and other operations.

[0042] Specifically, the working principle of the present scheme is:

[0043] When the charging pile starts to work, the cooling system controller 15 detects that the supply liquid temperature and the return liquid temperature in the pipeline reach the set temperature, and controls the water pump 3 to start. The water pump 3 draws the cooling liquid from the water tank 2, which is distributed to each high-heat component of the liquid-cooled charging pile through the cooling liquid distribution unit for cooling. The cooled cooling liquid returns to the water tank 2 through the return pipeline to form a closed loop circulation. At the same time, the heat exchanger 4 dissipates the heat in the cooling liquid to the air, and the cooling fan 5 adjusts different operating states according to the cooling liquid temperature to assist in heat dissipation and maintain the low temperature state of the cooling liquid.
