With the popularization of electric vehicles, charging piles, as an important facility for their energy supply, have attracted more and more attention for their performance and stability. Among them, heat dissipation technology, as an important part of the performance of charging piles, has also become the focus of the industry. At present, the heat dissipation technology of charging piles is mainly divided into three types: air cooling, liquid cooling and natural heat dissipation.
Comparison of heat dissipation technologies.
First, let's take a look at air-cooled technology. Air cooling technology mainly uses equipment such as fans to draw air into the charging pile, and then exhaust the heat through heat exchange. The advantages of this technology are simple structure and low cost, so it is widely used in some small charging piles. However, due to the relatively low heat dissipation efficiency of air cooling, air cooling technology may face the problem of insufficient heat dissipation for high-power charging piles.
Next up is liquid cooling. Liquid cooling technology mainly uses liquid coolants, such as water or oil, to take away the heat inside the charging pile. At the same time, liquid cooling technology can also dissipate heat to the outside through a recirculating system, avoiding heat accumulation. However, liquid cooling technology is relatively expensive and requires more complex maintenance and servicing.
Finally, there is the natural heat dissipation technology. Natural heat dissipation technology mainly uses the principle of natural convection to transfer heat into the air through heat sinks. The advantages of this technology are its simple structure, low cost, and the fact that it does not require additional energy consumption. However, the heat dissipation efficiency of natural heat dissipation technology is also relatively low, and it may face the problem of insufficient heat dissipation for high temperature and high humidity environments.
Advantages of charging pile cooling fan.
Efficient heat dissipation: The cooling fan of the charging pile can quickly take away the heat inside the charging pile and dissipate it into the environment. This is due to its excellent air flow performance and efficient heat dissipation design, which can quickly dissipate heat in a short time and ensure the stability of the internal temperature of the charging pile.
Long life and stability: The high-quality charging pile cooling fan adopts high standard materials and manufacturing technology, which has a long service life and stability. This means that during long-term use, the cooling fan of the charging pile can always maintain good heat dissipation performance, providing a strong guarantee for the stable operation of the charging pile.
Strong adaptability: The charging pile cooling fan has strong environmental adaptability and can work normally in different climatic conditions and environments. Whether it is a high-temperature, low-temperature, humid or dry environment, the cooling fan of the charging pile can maintain good heat dissipation performance and ensure the normal operation of the charging pile.
Energy saving and environmental protection: The cooling fan of the charging pile adopts a high-efficiency and low-noise design, which can not only meet the heat dissipation needs, but also will not produce excessive noise pollution. In addition, the cooling fan of the charging pile also has the advantages of energy saving and environmental protection, which can effectively reduce energy consumption and reduce the impact on the environment.
Easy maintenance: The design of the cooling fan of the charging pile fully considers the needs of maintenance. Its simple structure and easy disassembly and assembly make maintenance work easy and fast, and greatly reduce operating costs and maintenance difficulties.

EBMPAPST's Radical centrifugal fans R2E225 and R3G225 series have low power consumption, high efficiency and more energy saving; With a diameter of 225 mm, the compact design makes it suitable for use in narrow installation spaces; The large air volume of up to 1300m3 h makes the charging pile more efficient and has stronger heat dissipation capacity. EBMPAPST cooling fans can also operate normally in environments from -25 to 65, which greatly extends the service life of the charging station. It can be seen that the advantages of EBMPAPST charging pile cooling fan in charging pile are vividly exerted.
The ebmpapst axieco and axiforce series of fans are also proven in a wide range of e-mobility applications. Axieco's compact design, powerful performance and high efficiency enable users to optimize the final system design. The fan diameter is 200 mm and the air flow is 1,820 m h. It can be adjusted by PWM or analogue signals to suit the required cooling capacity, which minimizes operating noise. It can also be easily customized for specific applications, such as modifying electrical connections or the length of stranded plugs.
Ideal for high back pressure applications, the EBMPAPST AxiForce series of fans is available in sizes 80, 120 and 172 mm for pressures of up to 1,200 Pa. They have a steep air performance curve and are ideal for cooling needs in dense fast-charging stations. Despite the high back pressure, the airflow of up to 650 m h is achieved, which significantly improves the performance of the application.
To sum up, the heat dissipation advantages of the charging pile cooling fan are mainly reflected in the aspects of efficient heat dissipation, long life and stability, environmental adaptability, energy saving and environmental protection, and convenient maintenance. It is the existence of these advantages that makes the cooling fan a key factor to ensure the stable operation of new energy vehicles. In today's rapid development of the new energy vehicle industry, the selection of EBMPAPST charging pile cooling fans is very important to improve the use experience and life of new energy vehicles.
