XD Thermal Advances Side-Cooling Solutions for Cylindrical Cell Packs

XD Thermal Technology, a manufacturer specializing in thermal management solutions based in Suzhou, China, has recently announced the expansion of its side-cooling platform specifically designed for cylindrical cell-to-pack (C2P) battery packs. This innovative approach to cooling addresses the significant challenges posed by elevated temperatures during high current charging and discharging, common in fast-charging environments.

The Challenge of Heat Management

As battery performance increases, heat accumulation becomes a critical issue, particularly in cylindrical battery packs that operate with high charge and discharge rates. XD Thermal's side liquid-cooling concept is engineered to efficiently manage this heat by incorporating serpentine tubes along the cell sidewalls. This design enhances the effective contact area for cooling compared to traditional bottom cooling plates, thereby mitigating heat gradients and maintaining a consistent temperature range for each battery cell. Such temperature management is vital for extending the lifecycle of lithium-ion batteries.

Innovative Design and Reliable Quality Assurance

XD Thermal's development of a family of side-cooled modules and packs is geared towards robustness and reliability. Each system is structured to allow flexible combinations of cooling tubes with varying manifolds, brackets, and pipelines. The design incorporates validated flow-path structures that ensure predictable heat transfer performance from the initial prototype phase through to mass production. As emphasized by Guo, a technical engineer at the company, the platform-based approach significantly reduces development costs and times, ultimately facilitating agile product development.

In addition to innovative designs,XD Thermal has implemented rigorous quality assurance methods. By establishing confirmed development roadmaps and standard operating procedures (SOPs), they assure a repeatable and scalable production system capable of efficient ramp-up to meet growing market demands.

High-Volume Production Capabilities

As part of their strategy for meeting increased demand, XD Thermal has commissioned advanced production lines capable of manufacturing 30,000 serpentine tubes daily. This facility integrates advanced automation for forming, welding, and cleaning, as well as comprehensive leak testing protocols to guarantee product quality before delivery. Sun, the Head of Manufacturing Engineering at XD Thermal, underscores the importance of industrialization in keeping pace with product development, stating, "The ability to ramp up production and expand lines is just as crucial as the development of the products themselves."

Recognized Industry Partnerships

XD Thermal's capabilities have drawn attention from significant players in the automotive supply sector. In November 2025, they were officially recognized by OP Mobility, a tier-1 global automotive supplier, as a key supplier of thermal-management components. This acknowledgement marks a pivotal step in XD Thermal's trajectory within the evolving landscape of electric vehicle (EV) batteries where C2P packs are progressively dominating the market.

Future Outlook

Looking ahead, XD Thermal anticipates a surging demand for its side-cooling solutions in light of the rapid adoption of cylindrical C2P packs across various applications. With substantial production capacity and highly automated processes, XD Thermal is well-positioned to leverage this growing market segment while supporting the broader automotive industry's shift towards more efficient and durable battery technologies.

In summary, XD Thermal's commitment to enhancing the thermal management of cylindrical cell packs is set to reshape approaches to battery technology in the automotive sector, driving efficiency and reliability into the future.
