⚡ Pulsating Heat Pipe (PHP) / Oscillating Heat Pipe (OHP): High-Efficiency Cooling for Advanced Electronics
❓ What is PHP?
PHP is a sealed microchannel system partially filled with working fluid. Heat drives passive oscillation of liquid–vapor slugs via pressure differences from evaporation and condensation, transferring heat rapidly—no pumps, no moving parts.
✨ Key Advantages
1️⃣ High heat flux capability: Up to 100+ W/cm²
2️⃣ Flexible Integration: modules, PCBs, compact assemblies, etc.
3️⃣ Reliable: Long lifespan, passive operation
4️⃣ Lightweight: Lighter than copper, reducing fuel consumption.
🏭 Typical Applications
Aerospace, satellite, defense systems, edge AI hardware, compact GPU/FPGA, VPX, high‑density power modules.
🤝 How We Support You
We offer full‑cycle services: PHP design, thermal simulation, prototyping & volume production to solve your toughest thermal challenges.🔥
