Mass Production Ready High-Performance Stamped Aluminum Liquid Cold Plate for BESS

Application

Commercial & Industrial (C&I) Storage Cabinets: Ideal for 100kW to 1MW systems where quiet, condensed-format enclosures are required indoors and outdoors.
· Utility-Scale Containerized BESS: High-volume, repetitive production for 40ft containers, where stamped+bonded quality ensures field reliability across thousands of packs.
· Cold Climate Microgrids: The PU foam insulation prevents internal condensation, making it suitable for Canadian winters or high-latitude sites with extreme temperature swings.
· High-Vibration Transport: Riveted and foam-bonded structures excel in mobile BESS trailers or marine auxiliary power units, where shock and vibration are constant.

How It Works

The base of the battery module directly rests on the brazed cooling plate. As cells generate heat during operation, energy passes through a thermal interface layer into the coolant flowing inside the brazed aluminum plate, carrying the heat away to the HVAC chiller. Meanwhile, the PU foam bonded beneath the plate creates a thermal barrier to ambient humidity, preventing moisture formation inside the sealed enclosure. Mechanically, road shock or pack movement is absorbed by the foam core and the elastic riveted joints, rather than transmitting stress to the cell terminals. Finally, the powder-coated outer skin isolates the pack’s internal potential from the rack, preventing arc flash risks during installation and maintenance

How To Choose Your Stamped Cooling Plate

1. Heat Load & Flow Rate: Determine total watts to dissipate and available coolant flow (L/min). Our engineers use this to calculate required channel cross-section and plate size.
2. Stamped vs. Machined Design: For high volumes (>5,000 units/year), stamping offers dramatic cost and speed advantages. We help you decide if your geometry is suitable for stamping or requires a hybrid approach.
3. Channel Pattern Selection: Serpentine for simple, low-cost designs; multi-parallel for low pressure drop; dimpled or pin-fin for maximum turbulence and heat transfer. We recommend the pattern based on your thermal simulation inputs.
4. Surface Protection: Choose based on your coolant chemistry and environment. E-coat provides excellent corrosion resistance for water-glycol systems; hard anodizing adds electrical insulation for direct cell contact.
5. Project Timeline & Volume: Share your expected annual quantities and target SOP date. Our stamping die development lead-time is typically 4-6 weeks, with samples following shortly after. We manage everything in-house to keep your program on track.
