Seattle is rapidly becoming a focal point for the Electric Vehicle (EV) industry, driven by Washington State's aggressive clean energy mandates and the region's tech-heavy industrial base. As a premier EV Battery Cooling Manufacturer, we understand that the Pacific Northwest’s unique climate and logistics landscape require specialized thermal management. From the hilly terrains of downtown Seattle to the heavy-duty maritime requirements of the Puget Sound, battery cooling is no longer a luxury—it is a critical safety and performance component.
Current trends in Seattle show a massive shift toward electrifying public transit and heavy trucking. With companies like PACCAR (headquartered nearby) and regional transit authorities like Sound Transit leading the way, the demand for High-Voltage Liquid Cooling Systems has skyrocketed. Our factories provide the essential aluminum cooling tubes and radiators that keep these massive battery packs within optimal temperature ranges, ensuring longevity even under high-demand cycles.
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, Zhejiang Rock Auto has earned a reputation as a pioneer in the design and manufacturing of aluminum-based cooling products. We are committed to providing high-quality, cost-effective, and innovative solutions that meet the rigorous demands of our global customers, including those seeking advanced EV Battery Cooling Factories in Seattle and worldwide.
Our products are widely used in automobile, heavy industry, shipbuilding, sugar processing, packaging, navigation, molds, and other specialized applications. Our R&D unit is the cornerstone of our business, conducting detailed research to improve the performance and durability of our products.

Our Mission: To deliver high-quality and cost-effective cooling solutions that not only meet but exceed customer expectations, while fostering a culture of innovation and sustainability.
Our Vision: To be a global leader in the auto parts industry, recognized for our advanced technologies, outstanding customer service, and environmental stewardship.
Modern EV battery packs, especially those with high energy densities like the 100kWh-200kWh packs used in electric buses, generate significant heat during fast charging and high-speed discharge. As a Seattle EV cooling manufacturer, we focus on Liquid Cooling (Water/Glycol) systems over air cooling. Liquid cooling offers a thermal conductivity that is 25 times higher than air, allowing for a more compact pack design and more stable operating temperatures.
Our manufacturing process utilizes vacuum brazing for aluminum components, ensuring leak-free performance and maximum surface area for heat exchange. This is vital for the Seattle climate, where seasonal temperature shifts require a system that can both dissipate heat in the summer and potentially assist in battery warming during the damp, cold winters.
As an ISO/TS 16949 certified facility, Zhejiang Rock Auto leverages state-of-the-art technologies, including Brazing Furnaces, Fin Machines, and Core Assembly Machines. For businesses in Seattle and throughout the Pacific Northwest looking for a reliable EV Battery Cooling Manufacturer, we offer the perfect blend of high-volume manufacturing capability and precision engineering. Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) ensures that every cooling tube and radiator we produce contributes to a safer, more efficient electric future.
