XD Thermal Technology has strengthened its side-cooling platform for cylindrical Cell-to-Pack (C2P) battery packs.
In fast-charging cylindrical packs, heat accumulation during high current and voltage cycles remains a challenge. XD Thermal’s side liquid-cooling approach routes serpentine tubes along the cell sidewall, increasing contact area compared with bottom cooling plates. This enlarged vertical surface helps resolve heat gradients in the Z-axial direction, keeping each cell within a more balanced temperature range – a factor that supports longer Li-ion battery life.
The company has built a family of side-cooled modules and packs around robust structures and reliable QA methods. Cooling tubes are pitched to match cylindrical layouts and can be flexibly combined with manifolds, brackets and pipelines. Validated flow-path structures and internal design rules ensure predictable heat-transfer performance from prototype through to mass production.
“Platformised design reduces development cost and time and supports agile development for our customers,” said Guo, technical engineer at XD Thermal. “With proven solutions of pipeline connections, electrical insulation and geometric combinations, we helped many customers complete side-cooled battery development smoothly.”
In 2024, XD Thermal commissioned high-volume serpentine-tube lines with daily capacity of 30,000 pieces, integrating automated forming, welding, cleaning and full leak testing.
In November 2025, OP Mobility, a global tier-1 automotive supplier, nominated XD Thermal for thermal-management components. With cylindrical C2P packs gaining share in EV batteries, demand for side-cooling solutions is expected to rise, favouring suppliers with capacity, automation and mature design platforms.
