Comparison of air cooling and liquid cooling in energy storage systems With the acceleration of the global energy transition and the promotion of the "dual carbon" strategy, the energy storage industry, as a key component of the national energy revolution, is ushering in unprecedented development opportunities. With the increase of the proportion of new energy storage in China, the economy of industrial and commercial energy storage is gradually emerging, and the importance of sodium-ion batteries and all-vanadium flow batteries is growing. New trends such as independent energy storage and virtual power plants have also injected new vitality into the development of new energy storage industry. In the design and application of energy storage systems, the total heat dissipation technology of energy storage systems is a key factor to ensure the stable operation of the system. At present, air cooling and liquid cooling are the two most mainstream methods of heat dissipation. Compare from the following six dimensions: Liquid cooling mode Ⅰ: the heat dissipation principle is different Air cooling relies on air flow to take away heat, so that the surface temperature of the equipment is reduced, and the heat dissipation effect will be affected by factors such as ambient temperature and air circulation. Air cooling requires that there be a certain gap between the components of the equipment as an air duct, so the volume of the air-cooled cooling equipment is often larger. Liquid cooling is to reduce the internal temperature of the equipment through liquid circulation, requiring that the heating equipment components need to have good contact with the heat dissipation plate, and at least one side of the heat dissipation device is smooth and regular; The heat exchange of liquid cooling temperature control is ultimately lost to the outside world through the liquid cooling machine, because the equipment itself is equipped with liquid, so the liquid cooling equipment can achieve a relatively high level of protection. Ⅱ：Different application scenarios Air cooling is the most widely used cooling technology at present, and its technical maturity and reliability have been widely verified, especially in low and medium power scenarios, air cooling still occupies a mainstream position. Liquid cooling is more suitable for large-scale, high energy density energy storage projects. The advantages of liquid cooling are particularly obvious when the battery pack energy density is high, the charge and discharge speed is fast, and the ambient temperature changes are large. Ⅲ：Different heat dissipation effect The heat dissipation effect of air cooling is easily affected by the external environment, such as ambient temperature and air flow, so the heat dissipation demand for high-power equipment may not be met. Liquid cooling has good heat dissipation effect, can effectively control the internal temperature of the equipment, improve the stability of the equipment and exten...

As a noble social welfare cause, blood donation is a red bond that transmits the true feelings of the human world. Manufacturers of surge protectors Anhui Jinli actively responded to the call of the Party branch and Changning Center, and organized employees to participate in the high-tech Zone 2024 centralized blood donation activity. The early season has arrived, the summer heat, so hot weather did not resist the enthusiasm of Anhui Jinli employees to donate blood. At 8 o 'clock in the morning, the colleagues who signed up for blood donation came to the central blood donation point early, and under the guidance of the community staff, they orderly filled in the unpaid blood donation registration form. After blood pressure measurement and preliminary blood test, everyone rolled up their sleeves, stepped on the blood donation car in turn, donated their own blood, and demonstrated the strong sense of social responsibility and selfless dedication of Anhui Jinli employees with practical actions! Blood donation is not terrible, it only needs us a little courage and love, the lightning  SPD protection problem encountered in the process of enterprise electricity is not terrible, JINLI escort for everyone!

  On June 13th, the 17th (2024) International Solar Photovoltaic and Smart Energy (Shanghai) Conference was grandly held at the National Convention and Exhibition Center. This time, SNEC attracted more than 3600 companies from around the world to participate. As a long-time exhibitor of SNEC, Anhui Jinli made a grand debut with its photovoltaic storage products, solutions, and related technologies.   Jinli Electric has been rooted in the photovoltaic industry for more than ten years, and brought new products (DC2000V modular SPD, DC2000VPCBSPD, line lightning arrester acquisition terminals and collection units) to shine on the 6.1H-D520,whichreceiving numerous inquiries from photovoltaic storage enthusiasts and international friends. DC 2000V modular SPD and PCB SPD   With the continuous innovation of photovoltaic technology and material technology, the efficiency of batteries, insulation level of materials, and manufacturing process technology have made rapid progress, making higher system voltages possible. At the same time, the increase in system power density is conducive to reducing the cost ofPV systems, making the 2000V photovoltaic power station systemto bethe current development trend. The 2000V modular SPD used in combiner boxes and thePCB SPD used in inverters have emerged, and Jinli has mature SPD products supporting the DC2000VPVsystem. Energy storage lightning protection boxes and intelligent lightning protection systems lead the new trend of lightning protection   The energy storage dedicated intelligent lightning protection box is a high-end lightning protection unit that uses high current and low residual voltage functions internally, and utilizes modern power electronics technology to monitor the operation status of the lightning protection unit, store and analyze lightning data, and provide a human-machine friendly interface. The intelligent lightning protection box for energy storage is called the "reliable nanny" of the battery compartment, which integrates "high current", "low residual voltage", and "intelligence" technology. It is installed on the side of the junction box in the battery prefabricated compartment to achieve the best lightning overvoltage protection for the battery prefabricated compartment.   The intelligent lightning protection system is a solution that integrates advanced technology and intelligent management methods, aiming to provide comprehensive lightning protection measures for photovoltaic power stations and provide non periodic operation and maintenance guidance suggestions for the site. The system utilizes key technologies such as SPD online monitoring, lightning warning online monitoring, and grounding resistance online monitoring to monitor and analyze equipment status, lightning activity, and grounding system conditions in real time. Through intelligent algorithms and models, the system is able to predict the trend of lightning risk and the trend of SPD th...
