Ultra-Thin Brazed Cold Plate

For Battery Energy Storage System (BESS) Liquid Cooling

Stamped Components + Vacuum Brazing process – The Manufacturing Backbone

Mass 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 & Baseplate

Progressive die stamping ensures consistent channel depth (±0.05 mm) and flatness across high-volume runs

No secondary machining on flow paths – reducing cost and lead time

Material: corrosion-resistant aluminum (3003 or 6061-series) with optional chromate-free conversion coating

Vacuum Brazing – Joint Integrity at 3.0 mm

Brazing filler metal (clad layer) is pre-applied on the baseplate; during brazing, capillary flow creates a continuous, void-free bond

The thin wall withstands brazing thermal cycles without warping, thanks to controlled fixture clamping and ramp-rate profiling

Typical burst pressure > 2.5 MPa, leak rate < 1×10⁻⁶ mbar·L/s (helium) – reliable for long-term ESS operation

Built for High-Volume Production & Rugged Handling

At 3.0 mm, thin plates are prone to denting and warping during transfer. Vansim addresses this with:

Custom stacking trays with edge-support ribs

Automated pick-and-place with vacuum grippers (not mechanical clamps)

100% flatness check after brazing – out-of-tolerance parts are auto-rejected

All 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 Plate

Process maturity: Stamping + brazing line dedicated to thin-walled battery products

Flexible 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 weeks

Full traceability: Each plate laser-marked with batch ID linking to stamping press parameters, brazing furnace curve, and leak test results
