As the global automotive and industrial landscape transitions from internal combustion engines to electric propulsion, the Electric Battery System (EBS) has emerged as the most critical technological frontier. At Zhejiang Rock Auto Co., Ltd., we recognize that an efficient battery system is not merely about storage; it is about the harmony of thermal management, structural integrity, and electronic control.
The industry is moving toward Cell-to-Pack (CTP) and Cell-to-Chassis (CTC) architectures, which demand unprecedented precision in manufacturing. Our role as a leading OEM/ODM factory is to provide the cooling plates, high-frequency welded tubes, and structural components that enable these next-generation battery densities. By leveraging 15+ years of experience in heat exchange, we provide the "thermal backbone" that prevents thermal runaway and extends the cycle life of Lithium-ion and Solid-state batteries.
Global enterprises require partners who understand regional compliance. We offer localized documentation, EU/US standard compliance, and logistics optimization to minimize lead times.
From Dual-Material AL6061/C1100 stamping dies to bespoke cooling circuits, our ODM services allow for rapid prototyping and mass scaling of unique battery geometries.
As an ISO/TS 16949 certified factory, we provide rigorous quality audits and risk mitigation strategies to ensure your production line never stops.
The core challenge of modern electric battery systems is the management of heat during fast-charging cycles (3C and above). When a battery discharges or charges at high rates, the internal resistance generates significant joule heating. Without an Innovative Finned Tube or a Liquid Cooling Plate, temperature gradients can lead to "hot spots," drastically reducing the lifespan of the cells.
Our use of Alloy Aluminum 3003, 4343, and 7072 in intercooler pipes and radiator tubes is not accidental. These alloys offer the optimal balance between thermal conductivity, weldability, and corrosion resistance. For hybrid EV applications, our Dual-Material (Aluminum/Copper) stamping solutions provide superior heat extraction at the interface where battery cells meet the cooling circuit.
Structural integrity in a battery pack is paramount. Our High-Frequency Laser Welded Stainless Steel and Aluminum Tubes provide a leak-proof environment for coolants (glycol/water mixtures), ensuring that the electrical components remain dry and safe even under high-pressure scenarios.
Information Gain: Unlike standard radiators, battery cooling plates require 100% flatness tolerance and helium leak testing. Our facility employs Full Automatic Radiator Tank Clinching Machines and robotic assembly to meet these micron-level tolerances.
Focusing on Integrated Thermal Management Systems (ITMS) that combine battery cooling, motor cooling, and cabin HVAC into a single ultra-efficient heat pump loop.
Developing pressure-sensitive cooling plates designed for the high-pressure environment required by Solid-State battery cells to maintain interface contact.
Adopting 100% Recyclable Aluminum Alloys and low-carbon manufacturing processes to meet the EU's Battery Passport requirements and Carbon Border Adjustment Mechanism (CBAM).
Established in 2007, Zhejiang Rock Auto Co., Ltd. has been a leading manufacturer, exporter, and supplier of high-performance auto cooling system components. We specialize in producing a wide range of automotive cooling solutions, including radiator tubes, intercooler tubes, oil cooler tubes, as well as radiators, intercoolers, and oil coolers.
With more than 15 years of industry experience, we have earned a reputation as a pioneer in the design and manufacturing of aluminum-based cooling products. Our R&D unit is the cornerstone of our business, conducting detailed research and surveys to improve the performance and durability of our products. This commitment to innovation allows us to design new products with superior functionality, tailored to the specific needs of our clients.
