company news about How to improve the heat dissipation efficiency and extend the service life of commercial batteries through liquid cooling plates

In the development of modern new energy vehicles, commercial batteries such as lithium-ion batteries are favored by energy vehicle owners and companies because of their high energy density and long cycle life. However, with the iteration of new energy technology and the increase in load-carrying coefficient, the degree of temperature control has gradually become higher. Especially under complex working conditions of high current and high power, the problem of battery heat dissipation is particularly important. To this end, Trumony has produced a liquid-cooled plate with high heat dissipation performance. The liquid-cooled plate can realize disguised storage and effective use of energy by dissipating heat and insulating equipment, thus helping commercial batteries to be effectively used when they are put into formal use. Sex and science. Today, we will explain to you how to use liquid cooling plates to improve the heat dissipation efficiency and extend the life of commercial batteries!

How liquid cooling plates work

A liquid cooling plate is a device that uses liquid as a cooling medium to take away the heat generated by the battery. Compared with traditional air cooling systems, liquid cooling has a higher heat transfer coefficient and specific heat capacity, and can take away heat from the battery surface more quickly. Specifically, liquid cooling plates are usually composed of microchannel structures that can Allow the coolant to flow evenly within it to achieve efficient heat dissipation.

Adjustment and optimization of heat dissipation performance of commercial batteries

In order for commercial batteries to have higher heat dissipation effects, scientific adjustments and optimization must be carried out through a series of measures.

Optimize flow channel structure

Usually, different flow channel structures have a significant impact on the cooling performance of the liquid cooling plate. For example, the serpentine flow channel microchannel liquid cooling plate has proven to be an ideal choice for prismatic battery thermal management due to its compact structure and good heat dissipation effect. In addition, the flow channel structure can be further optimized through numerical simulation methods to improve its cooling performance.

Use related materials (PCM)

Relevant materials are introduced into liquid cooling systems because of their high latent heat properties. When the battery temperature rises, the PCM will absorb and store a large amount of heat, and release this heat when the temperature drops, thereby keeping the temperature of the battery stable. However, a single PCM system often cannot effectively suppress battery temperature rise. Therefore, some researchers have filled PCM with expanded graphite and constructed relevant materials to increase thermal conductivity and improve temperature uniformity.

Temperature control

Under normal circumstances, the operating temperature of the battery can be controlled within the optimal range, which is between 20°C and 50°C, through an effective liquid cooling system, thereby avoiding battery performance degradation and reduced safety caused by high temperatures. For example, commercial batteries produced by CATL can use double-sided liquid cooling plate technology to effectively and scientifically control the temperature, thereby successfully controlling the battery temperature within a reasonable range.

Continuous improvement and innovation

With the continuous advancement of technology, the design and application of liquid cooling plates are also constantly innovating with the advancement of technology. For example, the micro-channel cold plate structural design based on V-shaped grooves can greatly improve the heat dissipation capacity, making it reach 500W/cm² s level. In addition, some new liquid cooling tray and side plate structures are also being developed and applied to further improve heat dissipation efficiency and system stability when they are put into formal use.

As an indispensable and decisive material for commercial batteries, liquid cooling plate technology has profoundly affected commercial batteries and their energy storage systems. This material can not only significantly improve the heat dissipation efficiency of commercial batteries, but also effectively extend their service life. In the future, with the continuous development and innovation of liquid cooling technology, its application in the field of battery thermal management will become more extensive and in-depth. This will not only help improve the overall performance and safety of commercial batteries, but will also provide more reliable thermal management solutions for other high-energy-density equipment in new energy vehicles!
