Aerospace-Grade Thermal Reliability with Two-Phase Cooling

Performance engineered heat pipes and vapor chambers for satellites, avionics, and high-G airborne platforms used in the harshest conditions.

Aerospace Thermal Challenges

Increasing heat flux in compact payloads
Strict SWaP constraints
Launch vibration and shock
Thermal cycling (ground → orbit → eclipse)
Orientation changes and microgravity effects
Long-life reliability with zero maintenance

Why Two-Phase Cooling for Aerospace

Passive heat transport (no moving parts)
Extremely high effective thermal conductivity
Uniform temperature distribution
Reduced hotspot risk
Performance stability across orientation changes

Aerospace Thermal Reliability Considerations

Hermetic sealing and contamination control
Material compatibility and outgassing considerations
Wick structure selection for long-life operation
Working fluid selection for aerospace environments
Repeatable performance over extended mission durations
High-grade, fully traceable materials
