Product Description
Product Overview

Our integrated liquid cold plate is an all-in-one thermal management component combining stamping, brazing and integrated flow manifold design. This liquid cold plate integrates inlet/outlet ports, flow channels and heat dissipation substrate into a single sealed unit, eliminating extra connecting pipelines and reducing overall pack assembly complexity.

Compatible with prismatic, pouch, blade and partial large cylindrical cells, this liquid cold plate is widely deployed in grid energy storage systems, commercial EV battery packs and high-power power converter cooling.

All raw materials adopt high thermal conductivity Aluminum 3003 / 6061, balanced thermal conductivity and structural strength for long-cycle battery operation.

Advantages
  •  Excellent Temperature Consistency Optimized integrated manifold balance coolant distribution, max-min temperature difference controlled within ≤2℃, prevents battery local hot spots, extends lithium cell cycle life.
  •  Ultra-Reliable Hermetic Sealing Full vacuum brazed integrated structure, helium leak rate reaches ≤1*10⁻⁷ Pa·m³/s; burst pressure ≥1.5 MPa, stable under long-term hydraulic circulation and frequent cold & heat shock cycles.
  •  Compact Integrated Structure Built-in fluid ports and integrated flow distribution channels, fewer assembly parts, lower overall battery pack weight and smaller installation space. Plate thickness adjustable from 0.8–1.2mm for lightweight demand.
  •  Full Customizable Flow Channel Layout Parallel, series and hybrid flow networks available; we adjust channel width, spacing, manifold position and fin patterns based on customer’s battery module CFD simulation data.
  •  Long-Term Anti-Corrosion Performance Standard chromate-free passivation treatment, compatible with all mainstream water-glycol coolants; optional extra anti-corrosion coating for high-humidity or coastal working environments.
  •   Strict Zero-Defect Quality Control Every liquid cold plate undergoes hydraulic pressure test, helium leak detection and flatness inspection before delivery to avoid coolant leakage risks.

Solution – Trumony's Application-First Approach

We solve these problems by treating every cold plate order as a custom engineering project:

· Tailored to Your Module: Our engineering team works directly with your 3D module layout to optimize channel routing, port placement, and mounting features. No compromises, no wasted space.
· Full Certification Support: Every shipment includes complete material mill certificates, dimensional inspection reports, and individual helium leak test records. This documentation package directly supports your UL 1973 and UL 9540A submission.
· Consistent Manufacturing from Day One: We use the same precision stamping and sealing process for single prototypes as we do for 10,000-unit production runs. The thermal and mechanical performance you validate in the lab is what you get in the container.
· Optional Condensation Management: For installations in high-humidity climates, we offer integrated insulation layers and design features that mitigate cold surface sweating.

Application

· Electric Vehicle (EV) & Energy Storage Systems (ESS): Direct liquid cooling for prismatic/cylindrical battery modules and onboard chargers (OBC), preventing thermal propagation and enabling 4C fast charging.
· Data Center & High-Performance Computing (HPC): Cold plates designed for Intel Xeon, AMD EPYC, and NVIDIA GPU architectures; compatible with direct-to-chip (DTC) and immersion cooling loops.
· Medical & Aesthetic Lasers: High-uniformity cold plates ensuring stable wavelength output from diode laser stacks and IPL systems.
· Renewable Energy & Rail Transit: Thermal management for wind power converters, flexible DC transmission IGBT stacks, and traction inverters operating under harsh shock and vibration loads.

How It Works

Our liquid cooling plate operates on the principle of conjugate heat transfer. Waste heat generated by the active component conducts through the thermal interface material (TIM) into the cold plate's aluminum top plate. Beneath the surface, precisely machined or stamped internal fins — bonded via continuous brazing — interrupt the thermal boundary layer, forcing the coolant into a state of turbulent flow.

1. Heat Absorption: Coolant enters the inlet plenum at a controlled low temperature.
2. Turbulent Exchange: As the fluid navigates the serpentine or pin-fin channel, high-velocity mixing strips heat from the continuous brazed metal walls with maximum efficiency.
3. Efficient Exhaust: The heated fluid exits to a remote heat exchanger or chiller (CDU), dissipating the thermal load away from the sensitive components. This closed-loop circulation ensures zero contaminant leakage into the environment and maintains stable operating temperatures under fluctuating loads.

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.
