XD Thermal Expands Industrial Cooling Solutions for Cylindrical Cell Packs

Introduction

On November 26, 2025, XD Thermal Technology, a leading thermal management manufacturer based in China, announced significant advancements in their lateral cooling solutions designed for cylindrical Cell-to-Pack (C2P) battery configurations. This enhancement aims to tackle the thermal challenges associated with high-speed charging, a crucial aspect as electric vehicles and high-demand applications continue to rise.

The Challenge of Heat Accumulation

In high-performance cylindrical batteries, an essential challenge arises due to the heat produced during rapid charge and discharge cycles. The high current and voltage rates lead to increased temperatures, which can negatively impact battery lifespan. XD Thermal's innovative approach involves lateral liquid cooling, utilizing serpentine tubes that run along the cell walls. This method maximizes the effective contact area compared to traditional cooling plates, addressing heat gradients effectively along the Z-axis. The result is a more balanced temperature distribution, which is critical for extending the operational life of lithium-ion batteries.

Robust Platform Design

XD Thermal has developed a comprehensive range of cooling modules and packs that incorporate lateral cooling designs. The robust structure of these modules ensures reliable quality assurance processes. These cooling tubes are adaptable to various cylindrical cell layouts, allowing for flexible integration with different collectors, supports, and piping systems. Additionally, validated flow structures and internal design rules help predict thermal transfer performance from prototyping to mass production, thereby enhancing efficiency and reliability.

Technical engineer Guo stressed, "The platform design facilitates reduced costs and shortened development timelines, promoting agile development for our clients." Their experience with proven solutions in piping fittings, electrical insulation, and geometric combinations supports numerous clients in successfully developing lateral cooling batteries.

Commitment to Industrialization and Scalability

In 2024, XD Thermal ramped up production capabilities with new serpentine tube lines capable of manufacturing up to 30,000 pieces daily, featuring automated processes for forming, welding, cleaning, and 100% leak testing. Sun, the manufacturing engineer at XD Thermal, commented, "Scaling up production is just as vital as product development. We provide a scalable and reproducible manufacturing system with a confirmed development roadmap and standardized operating procedures, enabling us to effectively meet increasing production demands." The line preparation and tooling setup can typically be completed 6 to 8 weeks before production approval processes.

The company's capabilities have also garnered recognition from system-level clients. In November 2025, OP Mobility, a leading global automotive supplier, officially designated XD Thermal as a thermal management component provider within its supply chain.

Future Demand for Lateral Cooling Solutions

As cylindrical C2P batteries gain traction for use in electric vehicles and other high-demand applications, XD Thermal anticipates a surge in demand for their lateral cooling solutions. The company is well-positioned to meet this rising need, benefiting from significant production capacity, highly automated lines, and established design frameworks.

Conclusion

XD Thermal's advancements in lateral cooling for cylindrical battery packs mark a pivotal shift in addressing thermal management challenges within the rapidly evolving automotive sector. As electric vehicle technology progresses, such innovations in battery cooling will be fundamental to ensuring higher efficiency and longevity of battery systems, ultimately benefiting the industry and consumers alike.
