XD THERMAL Expands its Innovative Cooling Solutions

Based in Suzhou, China, XD Thermal Technology (XD THERMAL) has made significant strides in enhancing its cooling solutions specifically designed for cylindrical cell packs, also known as Cell-to-Pack (CTP) batteries. This evolution positions XD THERMAL as a vital player in the thermal management market, especially crucial for the burgeoning electric vehicle sector.

Addressing the Heat Challenge

In high-speed charging scenarios, maintaining optimal thermal conditions within batteries is critical. The unique challenge here is managing heat accumulation during both charging and discharging phases that often involve high currents. XD THERMAL has ingeniously developed a lateral liquid cooling concept, wherein serpentine tubes are integrated along the surfaces of the cylindrical cells. This design markedly increases the effective contact area compared to traditional cooling plates, effectively mitigating thermal gradients along the Z-axis. Each individual cell can thus remain within a balanced temperature range, which is pivotal for extending the lifespan of lithium-ion batteries.

Robust Manufacturing Capabilities

XD THERMAL has invested heavily in creating a family of lateral cooling modules and packs. These are built around solid structures complemented by rigorous quality assurance methods. The serpentine cooling tubes are configured to align seamlessly with the cylindrical cell designs, providing modular flexibility through various combinations of collectors, supports, and conduits. Verified flow structures and internal design rules support precise thermal transfer performance, bridging the gap from initial prototypes to mass production.

Guo, a technical engineer at XD THERMAL, stated, "The platform design helps to reduce costs and development timelines, while also encouraging agile development for our clients." This adaptability has proven beneficial, assisting numerous clients in advancing their own lateral cooling battery development projects.

Scaling Production

In 2024, XD THERMAL commenced high-volume production of serpentine tubes, achieving a daily output capacity of 30,000 units. This capability integrates automated processes such as forming, welding, and cleaning, alongside comprehensive leak testing to ensure quality. The welding quality is maintained through meticulous 360-degree 3D inspections across tubes, collectors, and related components, ensuring complete coverage and integrity of each weld.

M. Sun, XD THERMAL’s manufacturing engineering head, emphasized the importance of production acceleration and industrialization along with product development: "We provide a replicable and scalable production system, supported by a confirmed development roadmap and standardized operational protocols. Preparation for production lines and tools is typically completed six to eight weeks before the Production Part Approval Process (PPAP)."

This commitment to industrialization has led to recognition from key customers within the automotive industry. In November 2025, OP Mobility, a leading global automotive supplier, officially designated XD THERMAL as a thermal management component supplier within its supply chain.

Future Prospects

With the growing adoption of cylindrical C2P batteries in electric vehicles and various applications, the demand for lateral cooling solutions is anticipated to surge. XD THERMAL is poised to capture this demand through its robust capabilities, automated manufacturing lines, and mature design platforms. As the market for battery technology continues to expand, XD THERMAL's innovations will likely play a pivotal role in shaping the future of thermal management in energy storage solutions.
