Summary

Heat Pipes are among the most effective passive thermal-control technologies, enabling high heat-flux transport with no moving parts and exceptional reliability. With the rapid growth of high-power electronics, electrified transportation, data centers, and aerospace platforms (including small satellites), there is an increasing demand for compact, lightweight, and robust two-phase thermal solutions that can operate over wide temperature ranges and under challenging environments (e.g., microgravity, vibration, long transport distances, and variable heat loads). In this context, Heat Pipes (HPs) and Loop Heat Pipes (LHPs) offer excellent heat transport capability and flexible integration through remote evaporator–condenser architectures, while pulsating/oscillating heat pipes (PHPs/OHPs) provide a mechanically simple and scalable alternative with strong potential for miniaturization.

This Special Issue aims to bring together recent advances in materials, working fluids, design, modeling, testing, and reliability of HPs, LHPs and PHPs/OHPs, bridging fundamental understanding and application-driven development. Contributions are welcome from academia and industry, covering both original research and high-quality reviews.

Suggested themes include:
· Advanced wick structures, porous materials, and manufacturing routes (incl. additive manufacturing)
· Working fluids for high-temperature operation and demanding environments
· Design optimization, scaling laws, and thermal performance characterization
· Experimental diagnostics, metrology, and standardized testing methods
· Start-up behavior, stability, control, and transient performance
· Reliability, degradation mechanisms, contamination, and lifetime prediction
· Aerospace and high-heat-flux applications (spacecraft, avionics, power electronics)
