Precision Machined Cold Plate
Water Cooled Heat Sink for Power Amplifier
1. Basic Introduction
This is a high‑precision CNC machined liquid cooling cold plate
designed specifically for power amplifiers (RF / microwave / high‑power linear amp).
It uses water or water‑glycol as coolant to take away heat quickly,
far more efficient than air cooling for high heat flux.
2. Structure & Manufacturing
- Material: Aluminum AL6061 / AL5052 / Copper
- Process:
- CNC mill internal cooling channels
- Cover plate welded / brazed / sealed
- Pressure testing, leak testing
- Channels: serpentine, spiral, multi‑pass, or optimized for amplifier layout
3. Key Features for Power Amplifiers
- High heat dissipation: suitable for 100W–several kW amplifiers
- Uniform temperature: keeps RF performance stable
- Low thermal resistance: direct machining → no interface gap
- Compact & flat: easy to mount with PA modules
- Leak‑proof design: pressure tested up to 6–10 bar
- Corrosion resistance: can use deionized water or coolant
4. Why Use It for Power Amplifiers?
Power amplifiers (especially RF & high‑power) are very sensitive to:
- Temperature drift
- Thermal expansion
- Heat concentration
A precision machined water cold plate:
- Stabilizes gain & output power
- Extends amplifier lifetime
- Allows higher power density in smaller space
- Eliminates fan noise & dust issues
5. Typical Applications
- RF power amplifiers
- Microwave transmitters
- Broadcast power amplifiers
- Industrial high‑power amplifiers
- Military & communication amplifier modules
6. Compared to Other Coolers
- Better than air cooling: higher heat load, quieter
- Better than extruded cold plates: complex channels, higher performance
- Better than skiving heatsink: for extreme high power
