battery cooling brazed cold plate for energy storage cooling system
Ultra-Thin Brazed Cold PlateFor Battery Energy Storage System (BESS) Liquid CoolingStamped Components + Vacuum Brazing process – The Manufacturing BackboneMass production at this thin geometry cannot rely on traditional CNC-machined channels. We use high-speed stamping for both the cover plate and the baseplate, followed by precision vacuum brazing.Stamped Cover & BaseplateProgressive die stamping ensures consistent channel depth (±0.05 mm) and flatness across high-volume runsNo secondary machining on flow paths – reducing cost and lead timeMaterial: corrosion-resistant aluminum (3003 or 6061-series) with optional chromate-free conversion coatingVacuum Brazing – Joint Integrity at 3.0 mmBrazing filler metal (clad layer) is pre-applied on the baseplate; during brazing, capillary flow creates a continuous, void-free bondThe thin wall withstands brazing thermal cycles without warping, thanks to controlled fixture clamping and ramp-rate profilingTypical burst pressure > 2.5 MPa, leak rate < 1×10⁻⁶ mbar·L/s (helium) – reliable for long-term ESS operationBuilt for High-Volume Production & Rugged HandlingAt 3.0 mm, thin plates are prone to denting and warping during transfer. Vansim addresses this with:Custom stacking trays with edge-support ribsAutomated pick-and-place with vacuum grippers (not mechanical clamps)100% flatness check after brazing – out-of-tolerance parts are auto-rejectedAll parts are delivered with protective film on both sides and edge protectors for shipment.We have to also explain our disadvantages to you: The cost for the prototype will be higher, It's will perform well during mass production for the cost.Why Vansim for Your ESS battery brazed Cold PlateProcess maturity: Stamping + brazing line dedicated to thin-walled battery productsFlexible sizing: From 200×150 mm to 1200×600 mm, all with 3.0 mm baseline (other thicknesses available)Quick NPI: Prototype tooling in 4 weeks, production tooling in 6–8 weeksFull traceability: Each plate laser-marked with batch ID linking to stamping press parameters, brazing furnace curve, and leak test results
Electrical liquid cooling brazed cold plate mass production
Hybrid Welding Process Cold Plates: Brazed and FSW cold plate Our new-generation aluminum cold plates break away from conventional internal channel machining and single welding processes. We have pioneered an integrated manufacturing chain combining Friction Stir Welding (FSW) and vacuum brazing. Based on extruded aluminum profiles, the two welding processes are deployed with well-divided functional roles. Without compromising sealing reliability and thermal performance, this solution delivers high efficiency, low cost and high-volume mass production capacity urgently needed for consumer electronics and energy storage industries. Full Production Workflow: Standardized Assembly Line from Aluminum Extrusion to Finished Products1. Aluminum Extrusion Forming the flow channel as the baseCustom dies extrude hollow flat tubes and profiles with complex internal tooth structures, enabling one-step channel forming. The material utilization rate exceeds 95%. 2. End Sealing via Friction Stir WeldingEnd plugs are pressed in at high rotational speed to form a solid-state joint in an instant, creating hermetic flow channels with pressure resistance above 1.0 MPa.3. Brazed joints for the cold plateCNC-machined inlet and outlet joints are coated with brazing paste and fitted into reserved holes of cold plates, followed by treatment in a continuous brazing furnace. Hundreds of parts can be processed in a single batch, significantly cutting energy and labor costs per unit. 4. Precision Post CNC MachiningMounting surfaces, positioning holes and nozzle end faces undergo precision milling to guarantee flatness within 0.05 mm, meeting the tight mounting requirements of IGBTs and power modules. 5. Leak Testing & Finished Goods Dispatch100% mass leak testing is implemented to ensure zero-defect delivery.
