(The Thermal Crisis)
Fast chargers generate up to 85°C surface temperatures—enough to fry eggs. Traditional cooling fans add bulk, noise, and dust vulnerability. Our breakthrough: Piezoelectric Micro-Pump (PMP) cooling systems dissipate 30W heat in near silence (<20dB), shrinking thermal solutions by 70%.
(How PMP Works)
Core Innovations:
- Piezoelectric Actuation: Lead zirconate titanate (PZT) ceramic expands/contracts under AC current to drive diaphragm
- Micro-Jet Cooling: 0.1ml coolant per cycle targeted at chip hotspots
- Phase Change Heat Absorption: Coolant vaporizes at 60°C (latent heat = 4000× air specific heat)
(Performance Comparison)
| Traditional Fan Cooling | Piezoelectric Micro-Pump |
| Noise: 35-45dB (Vacuum cleaner level) | Operation: 19dB (Library ambient) |
| Size: 30×30×10mm fan + heatsink | Dimensions: 15×15×3mm micro-pump |
| Dust Resistance: Fails after 6mo (Clogged blades) | Sealing: IP68 liquid-tight loop |
| Response Time: 3-5 sec activation | Reaction: 0.2s thermal response |
