Energy storage liquid cooling plate is a key thermal management equipment, which plays a vital role in the energy storage system. The following is a detailed introduction to the energy storage liquid cooling plate:

First, Basic principles

The energy storage liquid cooling plate absorbs and takes away the heat generated by the energy storage device (such as the battery) during the working process through the liquid circulation. If the heat is not dissipated in time, it may lead to reduced equipment performance and even cause safety problems. Therefore, the role of the energy storage liquid cooling plate is to ensure the normal operation and safety of the equipment.

2. Structure and Design

Material selection: The energy storage liquid cooling plate is usually made of materials with good thermal conductivity, such as copper, aluminum, etc. These materials not only have good thermal conductivity, but also excellent corrosion resistance to ensure long-term stability.

Runner design: The liquid cooling plate is designed with a runner inside so that the coolant can flow and take away heat. The design of the runner needs to consider the flow speed and flow rate of the liquid to ensure the best cooling effect.

Safety performance: In emergency situations such as battery thermal runaway, the liquid cooling plate needs to be able to withstand high temperature and high pressure to avoid causing greater safety accidents. Therefore, the design of the liquid cooling plate usually includes safety measures such as safety valves and pressure sensors.

Types and characteristics

According to the different production process and heat dissipation method, the energy storage liquid cooling plate can be divided into many types, such as blowing, brazing, harmonica and so on. Among them, cold plate liquid cooling (indirect liquid cooling) is a more common type. It dissipates heat by direct contact with the heating element, or uses heat conduction components to conduct heat to the cold plate, and then takes away heat through the liquid circulation inside the cold plate. This kind of technology is relatively mature, and the cost of transformation is low.

In addition, there is an immersion liquid cooling (direct liquid cooling) technology, which completely immersing the cell in an insulating, non-toxic and heat-dissipating liquid. This liquid is able to directly contact the cell and carry away heat, enabling efficient thermal management. Submerged liquid cooling has significant advantages in energy storage systems, such as excellent thermal management, low failure rates, high space utilization, and the ability to adapt to a variety of harsh application environments.

4. Advantages and Applications

Efficient heat dissipation: the specific heat capacity of the liquid is much greater than that of the air, so the liquid cooling technology can reduce the temperature of the energy storage device to below the set value in a short time, improving the heat dissipation efficiency.

Good stability: liquid cooling technology can effectively avoid abnormal operation of equipment caused by changes in the external environment (such as temperature fluctuations), and improve the stability of the energy storage system.

High safety: The liquid cooling system can timely export the heat generated by the energy storage device, reducing the risk of battery overheating or even fire. At the same time, some advanced liquid cooling systems are also equipped with multiple safety precautions.

Small footprint: Compared with the air cooling system, the structure of the liquid cooling system is more compact, the system integration is high, and the footprint is small.

Energy storage liquid cooling plates are widely used in new energy power stations, data centers and other scenarios that require large-scale and long-term energy storage. In these scenarios, the energy storage device needs to run continuously and stably, and the heat generated is large. The traditional air-cooled heat dissipation method is difficult to meet the requirements, but the energy storage liquid cooling plate can solve the heat dissipation problem more effectively and improve the efficiency and reliability of the energy storage system.

V. Development trend

With the continuous development of energy storage technology, the design and manufacturing of energy storage liquid cooling plates are also constantly upgraded and improved. Future trends include efficient cooling, lightweight design and intelligent control. For example, by optimizing the flow path design and using more efficient coolant, the heat dissipation efficiency of the liquid cooling plate can be further improved; By using lightweight materials and innovative design methods, the weight of the liquid cooling plate can be reduced in order to better adapt to different application scenarios; By integrating the intelligent control function, the temperature and pressure of the energy storage equipment can be accurately monitored and controlled, thus optimizing the working performance and service life of the energy storage system.

In summary, the energy storage liquid cooling plate is an indispensable part of the energy storage system. It ensures the normal operation and safety of energy storage equipment through efficient heat dissipation capacity and excellent safety performance. With the continuous progress of technology and the continuous expansion of applications, energy storage liquid cooling plates will play a more important role in the future.
