At Embedded World 2025, Congatec unveiled an acetone-based heat pipe cooling solution explicitly engineered for sub-zero operating environments. The system addresses thermal management challenges in extreme cold conditions where traditional cooling mechanisms risk freezing and component damage. Yes, even at sub-zero environments the CPU still needs a dissipation medium as its heat density is still a problem. Operating reliably at temperatures as low as -40°C, the technology utilizes acetone's -95°C freezing point to maintain thermal transfer functionality in arctic environments. The solution resolves a fundamental limitation of water-based systems, which become inoperable at their 0°C freezing threshold. Despite water's superior latent heat of vaporization (2,260 J/g), its physical properties render it unsuitable for extreme cold applications.
Acetone's thermal properties prevent ice formation and reduce condensation risks, creating a stable heat transfer mechanism for polar research, high-altitude infrastructure, cold storage, and industrial automation in harsh climates. Imagine an edge server operating in the North Pole, needing to collect and process data locally before getting it to the research/scientist team. The solution integrates directly with Congatec's Computer-on-Module (COM) portfolio, including COMe, COM-HPC, and COM-HPC mini designs, eliminating the need for custom cooling system development. An optional heat pipe adapter will be available for specialized implementations. The company clarified that acetone-based cooling is purpose-built exclusively for extreme cold environments rather than general applications, as water remains superior for conventional temperature ranges due to its greater heat dissipation capacity, lower cost, and widespread availability.
