Why Phasurge
Why Phasurge
We turn phase-change direct cooling into a stable, controllable, deliverable system.
01
3× heat-transfer gain
Latent-heat-driven phase change targets cold-plate heat flux above 200 W/cm², 3× heat-transfer gain and cost close to conventional liquid cooling.
02
National-lab backbone
Built with support from a State Key research platform and Xi'an Jiaotong University's Energy & Power and Electronic Information schools.
03
AI+ full-stack control
In-house two-phase simulation platform + hardware-in-the-loop digital twin + multi-timescale AI optimiser — control response reaches the millisecond range.
04
Standardised test & delivery
CNAS-grade calibration, independent T-P-Q control and automated reports turn lab capability into product-grade quality.
