Эволюция технологии охлаждения пластин: белая книга 2026 года по штампованию, пачке и жидкому охлаждению для электромобилей и BESS

The Evolution of Cooling Plate Technology: A 2026 Whitepaper on Stamping, Brazing, and Liquid Cooling for EV and BESS

1. Market Data Overview: The Thermal Management Imperative

The thermal management component market, with cooling plates as a critical segment, was valued at approximately USD 8.5 billion in 2025. It is forecast to reach USD 28 billion by 2035. The EV battery cooling plate segment alone accounts for nearly 45% of this market, followed by the energy storage system cooling plate segment at 30%. The transition to 800V vehicle architectures and the deployment of gigawatt-scale BESS are the primary catalysts for this expansion, necessitating more efficient and reliable heat dissipation solutions than traditional air cooling can provide.

2. Industry Definition and Core Technologies

A cooling plate is a key component in liquid cooling systems designed to transfer heat away from high-heat-generating sources like lithium-ion battery cells. In applications such as EV battery cooling plates and BESS cooling plates, a coolant circulates through internal channels within the plate, absorbing and carrying away heat. The core manufacturing technologies defining the industry in 2026 are:

• Stamping Technology: Used for producing stamped cooling plates. This method involves pressing aluminum sheets into shape, offering high-volume production capabilities and cost-effectiveness.
• Brazing Technology: Used to create complex internal flow channels in brazing cooling plates by joining multiple aluminum layers, allowing for optimized thermal performance.
• CNC Machining: A traditional method for prototyping or low-volume, highly customized aluminum liquid cooling plates.

The primary driver for innovation is the need to balance performance (heat transfer efficiency, pressure drop) with manufacturability and cost, especially for mass-market EVs and large-scale BESS projects.

3. Regional Market Analysis

Asia-Pacific (The Manufacturing and Adoption Leader)

This region dominates both the production and consumption of cooling plates, holding over 65% of the global market share. China is the epicenter, home to leading manufacturers like Trumony Aluminum Limited, Sanhua, and Yinlun. The rapid domestic adoption of EVs and national energy storage targets fuel massive local demand for battery pack cooling plates and cooling plates for power storage.

Europe (The Innovation and Regulation Hub)

Europe is a key market driven by stringent automotive emission regulations and ambitious renewable energy goals. The demand for high-performance liquid cooling plates for EV from European OEMs pushes manufacturers towards advanced brazing and stamped solutions that meet rigorous quality standards like IATF 16949. Germany and France are major centers for both automotive and BESS applications.

North America (The Growth Frontier)

The North American market is experiencing the fastest growth, spurred by federal incentives for EVs and grid modernization. The demand for cooling plates for BESS is particularly strong, supporting the expansion of solar and wind farms. Local manufacturing is increasing, but a significant portion of components is still sourced from established Asian suppliers.

4. Key Market Trends for 2026-2035

1. Dominance of Stamped Solutions: Stamped cooling plates are gaining market share over CNC-machined plates for high-volume applications due to a 60% decrease in production time and 10% lower cost.
2. Material Standardization on Aluminum 3003: Aluminum alloy 3003 has become the industry standard for aluminum cold plates due to its excellent corrosion resistance, formability, and thermal conductivity.
3. Integrated Thermal Management Systems: Cooling plates are increasingly designed as part of a complete module, including serpentine cooling tubes and manifolds, simplifying assembly for OEMs.
4. Rise of Epoxy Coating: To ensure long-term reliability and electrical isolation in lithium ion cooling plate applications, epoxy coating is becoming a common special requirement.
5. Supply Chain Localization: To mitigate logistics risks, major OEMs are fostering regional supply chains for critical components like EV battery cooling plates.
6. Focus on Leakage Prevention: Quality assurance is centering on 100% air tightness and helium leakage tests to eliminate failure risks in the field.
7. Agile Customization: Manufacturers are offering greater flexibility, with minimum order quantities (MOQ) of 1 unit and customization of dimensions, cooling efficiency, and logos to serve diverse project needs.
