Product Description
Stamped & Brazed Liquid Cold Plate features flow channels formed by aluminum stamping and vacuum brazed into a sealed unit. Coolant circulates through continuous channels for efficient heat transfer. Leak-free and robust, with anti-corrosion coating, it is widely used for thermal control in battery packs and energy storage systems.
Product Features
Stamped Channel + Vacuum Brazed Sealed Structure
Two aluminum sheets are precision stamped with matched flow troughs, vacuum brazed together as one integral body to form smooth, continuous internal cooling passages without leakage gaps.
01
Custom Modular Multi-Zone Flow Channels
Multi-group parallel independent flow paths design evenly distributes coolant flow across the entire plate surface, eliminating local hotspots on large-area battery modules.
02
Uniform Flat Heat Contact Surface
Flat front working surface ensures full close contact with battery cells, maximizing heat exchange efficiency between cooling plate and heat sources.
03
Anti-Corrosion Protective Surface Coating
Uniform protective coating resists oxidation and coolant corrosion, extending service life under long-cycle liquid cooling operation.
04
Integrated Custom Mounting Structure
Perimeter pre-drilled mounting holes; customizable support standoffs, positioning lugs and edge profiles via CNC post machining for direct equipment assembly.

Advantages
Fully Seamless Vacuum Brazed Leakproof Performance
Unlike press-fit copper tube cold plates, vacuum brazing eliminates all hidden assembly gaps, zero risk of long-term coolant leakage under thermal expansion & contraction cycles.
Ultra-Even Heat Dissipation Across Large Panels
Wide multi-parallel stamped channels achieve balanced coolant flow across the full plate, perfect for large-capacity battery pack uniform temperature control.
High Structural Rigidity & Deformation Resistance
Integrated brazed monolithic structure resists bending deformation under heavy battery stack load, stable flatness during long-term operation.
Lightweight Large-Area Cooling Solution
All-aluminum construction lighter than copper tube cold plates of equal size, effectively reducing overall energy storage cabinet weight.
Flexible Full Customization For Battery Projects
Adjust channel layout, plate size, mounting hole distribution and support standoff height according to battery cell arrangement and cabinet internal space.
Extended Service Life With Anti-Corrosion Finish
Protective coating isolates aluminum base from acidic coolant, prevents metal oxidation and channel blockage, lowering post-maintenance costs.
