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.
· High-rate charging and discharging generate intense, localized heat that passive cooling simply cannot dissipate.
· Uneven temperature distribution across cells or IGBT substrates creates hot spots that accelerate aging and compromise safety.
· In mass production scenarios, inconsistent cooling plate quality — leaks, channel blockage, poor flatness — leads to costly field failures and warranty claims.
· Scaling from prototype to production with traditional machining methods becomes prohibitively expensive and slow.
The market demands a liquid cooling solution that combines high thermal performance with repeatable manufacturing quality and competitive pricing. This is where our stamped and continuous-brazed cold plates outperform alternatives.
Solution: Stamped Cold Plates with Continuous Brazing
Trumony's core manufacturing approach solves these problems through two key technologies:
Precision Stamping forms the coolant channel geometry by pressing aluminum sheet into precisely shaped dies. This method creates smooth, burr-free flow paths with excellent dimensional repeatability — critical for uniform thermal performance across every single plate in a production batch. Stamping also allows complex channel patterns, including multi-parallel and dimpled designs that enhance turbulence and heat transfer, without the cost and time penalties of CNC machining every part.
Continuous Brazing joins the stamped plate to its cover in a controlled-atmosphere furnace that moves parts through on a conveyor. Unlike batch vacuum brazing, continuous brazing delivers higher throughput, uniform joint quality along the entire plate, and consistently low leak rates. The result: a robust, hermetic seal trusted by automotive and energy storage manufacturers worldwide.
Combined, these processes give you a liquid cooling plate that performs flawlessly under pressure and thermal cycling — with the production capacity to support your ramp-up.Specifications

Application
1. Electric Vehicle Traction Battery Packs
Our stamped cold plates are installed between prismatic or pouch cell modules to maintain optimal temperatures during highway driving and DC fast charging. The high flatness ensures maximum contact with cell surfaces, while robust brazed joints withstand years of vibration and thermal cycling.
2. Commercial & Utility-Scale Energy Storage (BESS)
For containerized and cabinet-type storage systems using high-capacity cells. Stamped plates with multi-parallel channels keep dozens of cells within a 2°C temperature band, extending system life beyond 10,000 cycles and meeting UL 9540A safety test requirements.
3. IGBT & SiC Power Module Cooling
Power inverters, motor controllers, and renewable energy converters demand compact cold plates that handle extreme heat flux. Our pin-fin stamped designs maximize surface area directly beneath semiconductor substrates, reducing junction temperatures and preventing thermal throttling.
4. Automotive Ancillary Electronics
On-board chargers, DC-DC converters, and ADAS compute units also benefit from our lightweight stamped plates, which integrate easily into tight vehicle packaging envelopes.
How It Works
Stamped aluminum liquid cooling plates operate on a closed-loop liquid circulation principle. Coolant enters through an inlet fitting, flows through the stamped channel network beneath the heat-generating components, absorbs waste heat, and exits through an outlet to an external heat exchanger. The stamping process forms the intricate channel geometry directly into the aluminum sheet — creating raised features like dimples or chevrons that disturb the fluid boundary layer and enhance convective heat transfer. The cover plate is then joined via continuous brazing, where the assembly passes through a furnace with precisely controlled temperature and inert atmosphere. The brazing filler metal (typically a clad layer on the sheet) melts and forms a metallurgical bond along every contact point, creating a single, leak-proof structure. Because every plate undergoes identical automated processing, thermal performance is exceptionally consistent from the first unit to the millionth.
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.
