PHP/OHP Pulsating Heat Pipe Vapor Chamber: The Future of Passive Thermal Management
In the era of miniaturization and high power density, traditional heat pipes/vapor chambers face challenges. We’re highlighting a game-changing passive thermal solution: PHP/OHP (Pulsating/Oscillating Heat Pipe) Vapor Chamber.
Wick-free, it relies on working fluid gas-liquid pulsation for efficient 2D temperature uniformity and heat transfer—outperforming traditional solutions in ultra-thinness, anti-gravity, cost-effectiveness, and high power density.
🔑 Core Advantages
1. Simple Structure, Reliable & Cost-Effective: Microchannel arrays + working fluid (no wicks), easier to manufacture, longer lifespan, and resistant to clogging, aging, and vibration.
2. Exceptional 2D Uniformity: Heat diffuses rapidly, temperature difference ±1–3℃—ideal for CPUs/GPUs and multi-chip modules (local high heat flux).
3. Anti-Gravity & Omnidirectional: Gravity-independent (pressure/surface tension-driven), stable in any orientation (no heat loss like traditional inverted pipes).
4. Ultra-Thin: Thinner than traditional vapor chambers (≥2mm), perfect for thin electronics, AR/VR, and mobile devices.
5. High Heat Flux & Fast Response: Thermal resistance 0.05–0.3℃/W, withstands 100–500W/cm²—suitable for high-power chips and transient heat flux.
6. Flexible Design: Freely arranged channels for irregular heat sources; integrable with liquid cold plates/fins for composite cooling.
💡 Typical Applications
- Data Centers: CPUs/GPUs, edge computing servers (high uniformity, space-saving).
- New Energy: Battery packs, BMS, fast charging (anti-vibration, wide temperature range).
- 5G/6G & Optics: Optical modules, base stations (miniature, high heat flux).
- Industrial/Medical: Industry motherboards, medical imaging (high reliability).
- Aerospace: Satellite payloads, radar (zero/microgravity, long lifespan).
PHP/OHP vapor chambers enable next-gen thermal management for industries pursuing efficiency, miniaturization, and reliability. It delivers the performance and flexibility you need.
