[0002] With the rapid growth of the electric vehicle (EV) market, the performance and reliability of charging piles, as a key component of EV charging infrastructure, have received unprecedented attention. During the high-power charging process of the charging pile, especially in fast charging mode, the internal power conversion and control system will generate a lot of heat. If not effectively managed, this heat may cause the internal components of the charging pile to overheat, resulting in performance degradation, equipment damage and even safety hazards. Therefore, the development of an efficient and reliable cooling system has become the key to improving the performance of the charging pile and extending its service life.

[0003] Traditional charging pile cooling methods have certain limitations. For example, although the air cooling system has a fast response speed, its cooling effect is limited under continuous high-load working conditions, and it may increase noise and energy consumption due to long-term operation. On the other hand, although the water cooling system has high cooling efficiency, it is expensive, and has a slow response speed under low load or instantaneous high heat load conditions, which easily leads to waste of resources. In addition, a single cooling system is difficult to cope with the dynamic changes in the working conditions of the charging pile, especially in extreme weather conditions, where the cooling effect and energy consumption issues are more prominent.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] See also Figure 1-3 The present application provides a technical solution: a flexible and efficient charging pile cooling device, comprising a charging pile body 2, an upper cover assembly 1 is arranged on the upper surface of the charging pile body 2, and a charging group 3 is arranged on the front side of the charging pile body 2.

[0017] The upper cover assembly 1 is located on the top of the charging pile body 2 to protect important electronic equipment inside the charging pile from external environment damage, such as rain, dust, etc. The upper cover assembly 1 usually has vents to facilitate the dissipation of internal heat and prevent moisture and foreign matter from entering.

[0018] The charging group 3 is directly responsible for connecting with the charging interface of the electric vehicle to realize power transmission. The charging group 3 has good compatibility to meet the charging needs of different models. In order to ensure the safety of personnel and equipment during the charging process, the charging group 3 should also be equipped with overload protection, short circuit protection and other functions to prevent accidents.

[0019] The charging pile body 2 is provided with a power connection compartment 12, an electric control compartment 11 and a cooling compartment 7. The cooling compartment 7 includes an air cooling group and a water cooling group. The water cooling group is mainly composed of a circulating pump 9, a guide pipe group 14 and a cooling guide plate 13. The output end of the circulating pump 9 is connected to the guide pipe group 14. The cooling guide plate 13 is located inside the power connection compartment 12 and the electric control compartment 11, and the cooling guide plates 13 are arranged at intervals. A through hole for installing the guide pipe group 14 is provided in the cooling guide plate 13. The guide pipe group 14 passes through the cooling guide plate 13. The upper end of the guide pipe group 14 is connected to an upper support frame 4. The end of the upper support frame 4 is connected to the input end of the circulating pump 9.

[0020] The power connection compartment 12 is responsible for receiving power from the grid and converting it into a form suitable for charging the electric vehicle. Since a large amount of heat is generated during the power conversion process, thermal management of the power connection compartment 12 is critical to avoid performance degradation or safety hazards caused by overheating.

[0021] The electric control compartment 11 houses the control and monitoring system of the charging pile, including a microprocessor, a communication module and various sensors, which operate at a stable temperature to ensure accurate control signals and data processing capabilities.

[0022] The air cooling group and the water cooling group in the cooling chamber 7 work together. When the temperature exceeds the preset threshold, the external controller automatically adjusts the working status of the air cooling group and the water cooling group, gives priority to enabling the air cooling group for rapid cooling, and then calls the water cooling group for deep cooling as needed, to achieve intelligent regulation, effectively control the internal temperature, reduce the damage to components caused by thermal stress, extend the service life of the charging pile, avoid electrical failures caused by overheating, and reduce safety hazards.

[0023] The circulation pump 9 is responsible for driving the coolant to circulate in the system. When the circulation pump 9 is started, the coolant is extracted from the low-temperature end of the water cooling system and transported to the high-temperature area, namely, the inside of the power connection compartment 12 and the electric control compartment 11.

[0024] The guide pipe group 14 is a bridge connecting the circulation pump 9 and the cooling guide plate 13. The heat transfer is achieved through the flow of coolant in the pipe, ensuring that the coolant can be evenly distributed to improve the heat exchange efficiency.

[0025] The cooling guide plate 13 is located inside the power connection compartment 12 and the electric control compartment 11, in direct contact with the heat source, and the guide tube group 14 is installed through the internal through holes to form an efficient heat exchange interface. The interval setting of the cooling guide plate 13 is conducive to air circulation, enhances the effect of natural convection, and further improves the cooling efficiency.

[0026] The upper support frame 4 not only supports the guide pipe group 14 to ensure its stability and structural integrity, but also plays a role in connecting and guiding the coolant to flow back to the circulation pump 9 to form a complete cooling cycle.

[0027] Through the synergistic effect of the circulation pump 9, the guide pipe group 14 and the cooling guide plate 13, not only the thermal management efficiency is improved, but also the maintenance cost is reduced and the service life of the charging pile is extended.

[0028] The air cooling group consists of a fan group 5 and a fan mounting frame 15 . The fan mounting frame 15 is mounted inside the charging pile body 2 through fasteners. The fan mounting frame 15 is connected to the fan group 5 .

[0029] The air cooling group uses forced air convection to quickly remove the heat generated by the power conversion and control process inside the charging pile, thereby keeping the equipment running within an appropriate temperature range and ensuring the stability and safety of the charging pile.

[0030] The fan group 5 generates a strong airflow by rotating at high speed, which can quickly remove the heat around the internal components of the charging pile and achieve rapid cooling.

[0031] The function of the fan mounting frame 15 is to fix the fan group 5 and ensure its stable position inside the charging pile body 2. It is firmly connected to the internal structure of the charging pile body 2 through fasteners (such as screws or buckles) to ensure that the fan group 5 will not be displaced due to vibration during operation, affecting the cooling effect or generating noise.

[0032] When the charging pile is in operation, the heat generated during the power conversion and control process will cause the internal temperature of the charging pile to rise. At this time, the fan group 5 is started under the instruction of the controller, and the high-speed rotating fan generates a strong airflow to quickly discharge the hot air inside the charging pile and introduce cooler external air to form effective air convection, thereby quickly reducing the temperature inside the charging pile and protecting the internal electronic components from overheating damage.

[0033] Furthermore, a temperature sensor 16 is disposed inside the upper cover assembly 1, and a signal output end of the temperature sensor 16 is connected to an input end of an external controller, and an output end of the external controller is connected to a signal input end of the fan group 5 and a water cooling group.

[0034] The temperature sensor 16 can monitor the temperature inside the charging pile body 2 in real time and can accurately capture the slight changes in the internal temperature. Once the temperature is detected to exceed the set safety range, the temperature sensor 16 will immediately send a signal to trigger subsequent cooling measures.

[0035] When the internal temperature of the charging pile is too high, the external controller will activate the fan group 5 to accelerate the heat dissipation by increasing air flow; if the temperature continues to rise or is in a continuous high-load working state, the external controller will further start the water cooling group to utilize the high heat capacity characteristics of the liquid to absorb and transfer heat at a deeper level to achieve a more effective cooling effect.

[0036] Furthermore, the lower surface of the electric control compartment 11 is provided with support guide columns 10 , and four of the support guide columns 10 are located around the lower surface of the power connection compartment 12 .

[0037] The four support guide columns 10 ensure the stable support of the electric control compartment 11 , and also effectively prevent deformation or damage caused by gravity by dispersing the weight and load, thereby enhancing the stability and durability of the overall structure of the charging pile body 2 .

[0038] Furthermore, a support back plate 6 is provided on the rear side of the charging pile body 2, and the support back plate 6 is connected to an air cooling group.

[0039] Furthermore, the output end of the circulation pump 9 is connected to a nozzle connection seat 8 , and the upper end of the nozzle connection seat 8 is provided with a flange group connected to the guide pipe group 14 .

[0040] The nozzle connection seat 8 is the transition node of the coolant from the circulation pump 9 to the guide pipe group 14. The nozzle connection seat 8 can evenly distribute the coolant to each guide pipe according to the needs to ensure the consistency and maximization of the cooling effect. Through the flange group, a tight sealing connection is formed between the nozzle connection seat 8 and the guide pipe group 14 to prevent the leakage of the coolant, while ensuring the stability of the internal pressure of the system to avoid affecting the cooling efficiency due to pressure loss.

[0041] When in use: the temperature sensor 16 monitors the internal temperature in real time. Once the preset threshold is exceeded, the external controller automatically activates the cooling system. The air cooling group is activated first for rapid cooling. At this time, the fan group 5 is activated under the command of the controller, and the high-speed rotating fan generates a strong airflow, which quickly discharges the hot air inside the charging pile and introduces cooler external air to form effective air convection, thereby quickly reducing the temperature inside the charging pile and protecting the internal electronic components from overheating damage.

[0042] If the internal temperature of the charging pile body 2 continues to rise, the temperature sensor 16 exceeds the set threshold value. At this time, when the circulating pump 9 is started, the coolant is extracted from the low-temperature end of the water cooling system, and the circulating pump 9 transports the coolant along the guide pipe group 14 to the cooling guide plate 13. The heat transfer is achieved through the flow of coolant in the pipeline; the cooling guide plate 13 is located inside the power connection compartment 12 and the electric control compartment 11, in direct contact with the heat source, and the guide pipe group 14 is installed through the internal through hole to form an efficient heat exchange interface. At the same time, the upper support frame 4 guides the coolant to flow back to the circulating pump 9, forming a complete cooling cycle, further improving the cooling effect.

[0043] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
