Engineered Around Your System — Not a Standard Cold Plate
Thermal Performance
We optimize the thermal path from the heat source to the coolant to help reduce peak temperature and improve temperature uniformity.
Flow Distribution
Channel and manifold designs are optimized to distribute coolant where it is needed while avoiding low-flow regions and unnecessary flow resistance.
Pressure Drop
We balance channel geometry, coolant velocity and flow path to achieve the required cooling performance without creating excessive pumping demand.
Mechanical Integration
Mounting locations, flatness, interfaces, fittings and packaging constraints are considered from the beginning of the design.
How We Work
One Cold Plate.Multiple Ways to Build It.
The right manufacturing process depends on thermal performance, pressure requirements, geometry, production volume and cost. We help you select the process that fits the application—not simply the process that is easiest to manufacture.
You can find our working process for different cold plate: Vacuum brazed liquid cold plate, Radiator cold plate, Tig/Atmosphere cold plate, Tube embedded cold plate, Friction Stir Welding (FSW) cold plate & Gun drill cold plate
Cooling Plate Technology Comparison
| Technology | Best For | Key Advantage | Consideration |
|---|---|---|---|
| Vacuum Brazing | Complex internal channels | High design freedom | Requires tight brazing control |
| FSW | High-reliability aluminum plates | Strong solid-state joint | Welding path must be DFM-ready |
| Embedded Tube | Moderate heat loads | Simple, cost-effective construction | Limited channel flexibility |
| Gun Drilled | Straight/high-pressure channels | Robust construction | Limited channel geometry |
| TIG / Welded | Prototypes & special structures | Flexible fabrication | Welding distortion must be controlled |
| Radiator Type | Large-area cooling | High surface area | Application-dependent structure |
