Precision Machined Cold Plate

Water Cooled Heat Sink for Power Amplifier

1. Basic Introduction

2. Structure & Manufacturing

• Material: Aluminum AL6061 / AL5052 / Copper
• Process:
  1. CNC mill internal cooling channels
  2. Cover plate welded / brazed / sealed
  3. 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?

• Temperature drift
• Thermal expansion
• Heat concentration

• 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
