“长三角”电池液冷板产业链深度盘点

Core Viewpoint - The article emphasizes the importance of liquid cooling technology in the electric vehicle and energy storage markets, highlighting the emergence of key suppliers in the Yangtze River Delta region that possess core welding and precision processing capabilities [2]. Group 1: Liquid Cooling Plate Technology Routes - The liquid cooling plate technology is categorized into four main types based on manufacturing processes and application scenarios: 1. Roll-bonded: This method involves two layers of aluminum plates, which are combined and inflated to form flow channels. It is cost-effective, has high heat exchange efficiency, and is widely used in cost-sensitive passenger vehicles and small energy storage systems [3]. 2. Stamping & Brazing: This technique involves stamping aluminum plates into flow channel shapes and connecting them with a cover plate through vacuum brazing or continuous brazing. It offers high structural strength and flexible flow channel design, making it suitable for complex thermal management needs, currently the most mainstream solution for power battery packs [4]. 3. Extruded/Harmonica Tube: This method uses molds for direct extrusion, followed by cutting and welding. It has excellent pressure resistance and high standardization, commonly used in commercial vehicle battery packs or standardized energy storage modules [6]. 4. FSW/Diffusion Bonding: This solid-state connection technology achieves sealing through physical pressure or atomic diffusion, providing high weld strength and superior sealing performance, ideal for high-end passenger vehicles, marine applications, military, and high-power heat dissipation fields [9]. Group 2: Key Companies in the Yangtze River Delta - A compilation of over 30 core manufacturers in the Yangtze River Delta region specializing in battery and energy storage liquid cooling plates includes: - Sanhua Holding Group: A global leader in thermal management, providing system-level solutions and control components for automotive, building HVAC, and home appliances [11]. - Zhejiang Yinlun Machinery: A leading listed company in thermal management with four core product platforms, serving commercial vehicles, passenger vehicles, new energy, and industrial sectors [11]. - Jiangsu Jingyan Technology: A leader in MIM technology focusing on edge computing liquid cooling and precision structural components for consumer electronics, automotive, energy storage, and servers [11]. - Kexin New Energy (Ruitai): Offers various types of power/storage liquid cooling plates, including roll-bonded and stamping & brazing types, for power batteries, energy storage, and 5G communication [11]. - Nabichuan New Energy: Provides a full range of cooling plates including harmonica tube, stamping, and extruded types for automotive engines and power battery thermal management [11]. - Suzhou Zhengbei Connection: Focuses on connector and liquid cooling connection solutions with core patented conductive technology for new energy vehicles, energy storage, and data centers [11]. - Changzhou Hengchuang Thermal Management: Engages in automated production across the entire industry chain, including heat dissipation modules, heat exchangers, and components for automotive, energy storage, base stations, and refrigeration [11]. Group 3: Upcoming Industry Events - The FINE 2026 Thermal Management Liquid Cooling Plate Industry Exhibition is scheduled for June 10-12, 2026, at the Shanghai New International Expo Center, featuring a comprehensive coverage of the industry chain and showcasing the latest technologies in roll-bonding, brazing, and friction welding [13][14].
