ESS energy storage cooling plate

Product Description
Product Overview

Our water cooling plate (liquid cold plate) is a core thermal management component designed for battery pack and ESS energy‑storage systems. Made of high‑quality aluminum alloy, manufactured by stamping and vacuum brazing process. Optimized internal flow channels deliver excellent heat transfer performance, maintain uniform temperature distribution across battery modules, reduce hot‑spot risk and extend battery service life.

We support full customization: size, flow channel pattern, interface position, surface treatment can be adjusted according to your drawing or thermal simulation requirements. Samples and mass‑production orders are both acceptable.

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.

Application

Trumony customized liquid cold plates serve mainstream high-standard thermal management projects across North America, European Union, Japan, South Korea and Singapore, covering 4 core industries:
  1. New Energy Electric Vehicles: Passenger EVs, electric pickup trucks, commercial buses, mining electric vehicles; cooling for prismatic, 4680 cylindrical and pouch lithium battery packs, bottom & side dual cooling layout matching CTP/CTC integrated battery design.
  2. Energy Storage System (ESS): Grid-scale outdoor BESS power stations, industrial commercial energy storage cabinets, household backup energy storage, solar-wind hybrid microgrid storage equipment.
  3. Data Center & High-Performance Computing: AI GPU servers, supercomputers, liquid cooling retrofitting for cloud data centers, high-density rack CPU cooling microchannel cold plates, helping clients reduce PUE to 1.05–1.2.
  4. Industrial Power & Precision Equipment: PV inverters, wind power converters, SiC/IGBT power modules, high-power laser cutting machines, 5G macro base station power supply cooling.

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 The Right Trumony Liquid Cold Plate

Follow our 4-step professional selection guide to match cost-effective cold plate solutions for your regional projects:
  1. Confirm your core application & battery type
  • Mass-produced passenger EV & low-cost household ESS: Select roll-bond stamped aluminum liquid cold plates, lightweight and high-volume production friendly.
  • 18650/4680 cylindrical battery packs: Adopt embedded serpentine tube cooling plates for tight contact with cylindrical cells.
  • High-heat-flux AI server & high-performance computing: Choose microchannel copper cold plates for ultra-even temperature control.
  • Large grid energy storage & high-pressure industrial inverters: Friction stir welded or vacuum brazed cold plates for maximum sealing and pressure resistance.
  1. Match local regional climate conditions
  • Cold regions (Canada, Northern Europe, North Japan): Support glycol anti-freeze coolant matching design.
  • Humid coastal areas (Southeast Asia, West Europe): Provide extra nickel-plating anti-corrosion surface treatment.
  • Long-term continuous operation projects: Upgrade to 2.0–3.0MPa reinforced welding cold plates.
  1. Confirm installation space customization requirements

    Submit battery pack 3D CAD drawings, reserved cabinet size, inlet/outlet connector position to our engineering team; we optimize flow path layout to lower system pressure drop and save overall equipment space.
  2. Get free thermal simulation if you lack mature design

    If you do not have finalized cold plate parameters, send equipment rated power, maximum heat generation and continuous working temperature range. Our thermal R&D team delivers free heat dissipation simulation analysis and targeted quotation within 24 working hours for all global clients.
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.
