Engineered by Trumony Aluminum Limited, this Battery Pack Lower Enclosure adopts a multi-process aluminum manufacturing approach that prioritizes production efficiency and consistent quality. Instead of conventional steel welding or expensive full-machining, we utilize high-precision stamping for the main tray structure, followed by a vacuum brazing process to create a leak-proof, integrated liquid cooling plate. Self-piercing riveting (SPR) is employed to assemble multi-layer structural reinforcements without thermal distortion, while a polyurethane (PU) foaming process delivers superior vibration damping and condensation prevention. Finally, an electrostatic powder coating finish delivers excellent insulation and corrosion resistance. This enclosure solution meets the demands of North American commercial and utility-scale energy storage projects, offering an ideal balance of thermal performance, lightweight design, and mass production scalability.
In mission-critical energy storage, common failures often start from the bottom. Inferior lower enclosures lead to three major risks:
· Thermal runaway propagation: Without integrated cooling, heat builds up between cells, accelerating degradation and creating safety hazards.
· Environmental ingress: Dust, salt spray, and standing water corrode steel housings and cause ground faults, especially in coastal or desert utility sites.
· Structural fatigue: Constant vibration during transportation and seismic events can crack conventional welded steel trays, compromising pack integrity.
A standard battery housing simply cannot meet the demanding life cycle of 10+ years expected by North American project developers and asset owners.
· Built-in Liquid Cooling Gallery: Serpentine flow channels are CNC-machined into the thick aluminum baseplate, allowing direct contact with the module thermal interface. This ensures cell temperatures stay within a tight ±2°C band.
· Monolithic Sealing via FSW: Friction stir welding creates a solid-state bond stronger than the parent material itself, with no filler metals or porosity. This enables a true, maintenance-free IP67 seal across the entire tray.
· Lightweighting without Sacrifice: Using 6061-T6 aluminum, we deliver the same mechanical strength as steel at less than half the weight, reducing shipping costs and easing installation.
· Corrosion-Free Lifecycle: With a chromate conversion coating and optional electrophoretic paint finish, the enclosure withstands over 1,000 hours of salt spray testing, perfect for marine and humid continental climates.
· Custom Engineering Support: Send us your module layout, and we will optimize the cooling circuit, mounting bosses, and cable entry positions. Whether you need a prototype or volume supply, Trumony’s aluminum manufacturing ensures a consistent, premium product.

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.
Simply reach out with your requirements. We return a comprehensive proposal including die design feasibility, CFD thermal report, and transparent cost breakdown for prototype, pilot, and mass production phases.
Absolutely. That is the core of our one-stop service. Share your heat load, space envelope, and target thermal performance. Our engineers will propose an initial flow channel design, run CFD simulations for your approval, and then move to prototype. We guide you from idea to serial production.
We have no fixed MOQ for the prototype and NPI (New Product Introduction) stage. For mass production, we work flexibly with your volumes. As a factory serving global clients, we comfortably handle everything from small pilot runs to millions of pieces annually.
Quality is built in from the start. We use vacuum brazing for high-integrity joints and 100% test every single plate with a helium mass spectrometer, achieving leak rates tighter than 1×10⁻⁹ Pa·m³/s. Additionally, we conduct pressure cycling and thermal shock tests on pre-production samples validated according to customer durability requirements.
Yes. Our manufacturing is certified to ISO 9001 and IATF 16949. Our materials and components comply with RoHS, REACH, and UL standards as required by your product. We are also experienced in supporting customers through final system-level UL 9540A or UN 38.3 certification by providing detailed design and material documentation.
We stand behind our workmanship. Our standard product warranty is 5 years when properly operated within specified parameters. In the rare event of an issue, our engineering team provides root cause analysis and works to resolve it immediately. For ongoing production, we maintain complete traceability records tied to each batch.
