In order to improve employees' awareness of fire safety, create a safe production environment for surge protection device, and enhance employees' rescue organization ability and emergency escape ability for fire and other safety accidents, on August 6, 2024, Anhui Jinli organized all employees to participate in fire safety training and emergency drills. Before the drill, the teachers of the Fire Education Center analyzed the recent fire accidents. These bloody lessons remind us that we must always stay vigilant, master the necessary fire knowledge and put out small fires in a safe situation can save our own lives and the lives of others. Then Mr. Jiao explained the professional knowledge of fire safety and the precautions for exercise. The fire drill activity simulated fire emergency escape and work area fire drill and other links. The drill started from the surge protector workshop. After the smoke filled and the fire alarm was triggered, all employees quickly switched to the emergency state and efficiently and orderly escaped and evacuated to the designated safe area. After all the staff arrived at the safe area, Teacher Jiao evaluated the performance of the staff observed during the escape process, pointed out the problems in the escape drill, and further improved the staff's emergency handling ability in the face of emergencies. And make detailed demonstration and professional guidance on the use of fire extinguishers that need to be used in the next step. Subsequently, under the command of the person in charge of the on-site command, the fire fighting drill in the working area officially began. The crew lit the barrel and the fire caught fire in the wind. The team members cooperated and skillfully used fire extinguishing equipment, and the "fire" was extinguished in less than one minute. Through this fire safety training and actual combat exercise, the fire safety awareness of employees has been further enhanced, and the emergency escape ability and self-protection ability of employees in emergency situations have been improved, so that employees have been well trained and educated in the exercise, so that the policy of prevention first and combination of prevention and elimination can be better implemented in Jinli . In the follow-up, Anhui Jinli will gradually strengthen the safety education and training of employees, make corresponding safety plans, and ensure that the safety production of the SPD workshop is effectively guaranteed!

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.
