Product Description

Product Overview

Our stamping and continuous brazing water cooled plate is high‑efficiency aluminum thermal management component engineered for energy storage, electric vehicle and high‑power electronic projects across North America. We adopt precision stamping to form internal cooling channels, followed by continuous brazing to achieve full metallurgical bonding between two aluminum plates. This manufacturing route delivers low thermal resistance, excellent flatness and reliable leak‑tight performance for mass‑volume production. Compared with traditional CNC‑machined cold plates, stamped brazed water cooled plate balances thermal performance, weight and unit cost, supporting large‑scale OEM & ODM customization for North‑American battery system integrators and power equipment manufacturers. Every unit goes through strict leak detection before shipment to meet long‑term outdoor and industrial operating requirements.

Cause – Why Your Battery Pack Needs a Superior Lower Enclosure

Poorly designed or manufactured cold plates introduce significant risks into battery packs:

· Fluid Leaks: Gasketed or traditionally welded plates are susceptible to thermal fatigue and aging, causing dangerous coolant leakage onto high-voltage components.
· Hot Spots: Inconsistent channel depth or flatness creates uneven thermal contact, leading to cell degradation and potential thermal runaway triggers.
· Production Limitations: Many high-precision plates rely on slow CNC machining, limiting throughput and raising costs for large-scale BESS deployments.

Solution – Trumony's Stamped & Sealed Cold Plate
We address these challenges with a design optimized for both performance and production:

· Stamped Precision: Progressive stamping forms channels in seconds, guaranteeing repeatable geometry, excellent surface flatness, and low manufacturing cost at scale.
· Monolithic Sealing: Our solid-state joining technique eliminates gaskets and filler metals, creating a continuous bond that permanently prevents external leaks and internal channel bypass.
· Proven Leak Integrity: 100% helium leak testing verifies that every plate meets or exceeds a leak rate of <1×10⁻⁷ mbar·L/s, ensuring a life cycle of 15+ years without maintenance.

Stamping Continuous Brazing Aluminum Water Cooled Plate for ESS EV Power Electronics

Solution

We form inner coolant channels by high‑precision die stamping, realizing flexible channel layout to match prismatic battery modules, rack‑mount ESS cabinets and power inverters. Continuous brazing technology creates uniform, void‑free metallurgical joints over the whole bonding interface, delivering outstanding anti‑leak performance and high burst pressure capacity. Our aluminum alloy substrate offers good thermal conductivity while keeping light weight. Strict fixture control during brazing minimizes plate warpage, preserving superior flatness for thermal interface contact. All finished parts pass 100% air leak test, optional helium leak inspection and hydrostatic pressure test. We support full customization: dimensions, channel pattern, connector position, surface treatment and insulation coating according to your CAD drawings or thermal simulation data. With IATF16949 and ISO9001 quality management system, we offer prototype sample service and large‑volume mass production capacity for North‑American ESS, EV and industrial power projects, helping you cut total cost without sacrificing thermal reliability

FAQ

Q1: I don’t have a finalized design. Can you help from the concept stage?

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.

Q2: What is the minimum order quantity (MOQ) for custom liquid cooling plates?

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.

Q3: How do you ensure zero leaks in a water-cooled battery pack?

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.

Q4: Do you hold certifications for the North American and Asian markets?

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.

Q5: What kind of warranty and after-sales support do you offer for your cooling plates?

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.
