Aluminum liquid cold plates: the core of heat dissipation in new energy vehicles and energy storage

New Energy Vehicles: Aluminum Liquid Cold Plates Support Efficient Battery Operation

Aluminum liquid cold plates have become a mainstream choice for cooling power batteries in new energy vehicles. Leveraging aluminum's excellent thermal conductivity (reaching 160-200W/(m・K)) and molding advantages, they can quickly dissipate heat generated by the battery cells during operation. Industry data shows that battery packs using aluminum liquid cold plates achieve over 40% higher heat dissipation efficiency than traditional air-cooled systems, tightly controlling the temperature difference within the battery module to within ±2°C. This feature effectively prevents capacity degradation caused by localized overheating and extends battery cycle life by over 20%.

Currently, aluminum liquid cold plate technology adapted for 800V high-voltage fast-charging platforms is continuously being upgraded. Using a "microchannel integrated molding" process, dozens of fine flow channels are extruded within the aluminum profile, ensuring uniform coolant distribution. A single liquid cold plate can achieve a heat dissipation output of up to 8kW, meeting the high-volume heat dissipation demands of fast charging within a short period of time. In terms of material selection, 5-series aluminum alloy has become the mainstream. After treatment, its tensile strength can reach 280 MPa. It has passed vibration cycle tests exceeding 100,000 times and fully meets the vehicle's service life standard of 150,000 kilometers. In terms of market application, the installation rate of this type of aluminum extrusion liquid cooling plate in domestic new energy vehicles has exceeded 65%. With the continued popularity of high-voltage fast-charging models, market demand is expected to increase by 30% this year.

In battery pack structural design, the integrated "aluminum extrusion frame + liquid cooling plate" solution is gradually gaining popularity. Combining the liquid cooling plate with the aluminum extrusion frame creates an integrated module that combines structural support and heat dissipation. Compared to traditional split designs, the overall battery pack weight is reduced by 15% and production line assembly efficiency is increased by 25%. Moreover, by adjusting the cross-sectional dimensions and flow channel design of the aluminum extrusion, it can be flexibly adapted to battery packs of varying capacities and layouts. It has now become a standard solution for mid- to high-end new energy vehicles. Energy Storage: Aluminum Liquid Cooling Plates Improve System Safety and Energy Efficiency

As energy storage systems evolve toward higher density and larger capacity, demand for aluminum liquid cooling plates has increased significantly. Energy storage battery compartments utilizing aluminum liquid cooling offer significant advantages in heat dissipation efficiency. Compared to air-cooled solutions, they increase energy density by 20% and accommodate 15% more battery capacity within the same space. Operating noise is also reduced to below 55 decibels, making them ideal for noise-sensitive energy storage environments such as suburban areas, industrial parks, and indoor locations.

The new aluminum liquid cooling plate for energy storage features innovative structural design. Its "zigzag flow guide" structure, formed through an aluminum extrusion process, creates turbulent flow within the coolant, enhancing heat transfer with the plate wall and increasing the heat transfer coefficient by 18%. At only 3mm thick, this liquid cooling plate is 40% lighter than a copper liquid cooling component of the same specification, reducing the load-bearing pressure on the energy storage cabinet and meeting the environmental requirements for long-term outdoor operation of energy storage systems. At the system integration level, aluminum extruded liquid cooling plates utilize a modular design with standardized assembly interfaces with energy storage cabinets. Individual plates can be independently removed and replaced, significantly reducing the difficulty and cost of ongoing maintenance. In practical applications, energy storage systems utilizing this liquid cooling solution have achieved operational efficiency improvements of up to 92%, while energy losses during charging and discharging have been reduced by 15%. Currently, these plates are being deployed in multiple large-scale energy storage power stations.

Industry trends indicate that aluminum extruded liquid cooling plates are evolving toward thinness, integration, and high reliability. While the new energy vehicle sector places increasing demands on lightweight and vibration-resistant liquid cooling plates, the energy storage sector prioritizes heat dissipation uniformity and long-term operational stability. Leveraging its combined advantages in material performance and processing, the application penetration rate of aluminum extruded liquid cooling plates in these two sectors is expected to exceed 70% this year.
