Liquid cold plates
Aluminum liquid cold plates move heat through a fluid loop — the solution for high-density power electronics, batteries and EV charging where air cooling isn't enough.
When to choose a cold plate
A liquid cold plate (or aluminum cold plate) transfers heat from a device into coolant circulating through internal channels. We build them by machining flow paths into aluminum plates and closing them with friction stir welding or brazing for a leak-tight seal.
Used for inverters, energy-storage cells, IGBT stacks and battery cooling plates.
Typical specs
- Join: FSW / brazed
- Leak test: helium / pressure
- Flow: per your pump curve
- Finish: anodized or bare
Capability
| Parameter | Capability |
|---|---|
| Construction | milled channels + FSW/braze |
| Leak test | helium / hydrostatic |
| Thermal | flow uniformity ±5% typical |
| Finish | anodized / as-specified |
Design tip
- Share coolant type, flow rate and pressure limits up front.
- FSW gives a strong, clean weld with low distortion.
