Embedded World: Heatpipe cooling for COM-HPC computer modules

Pushing back against ever hotter computer-on-modules, Congatec is offering heat-pipe based heatsinking, using acetone as a working fluid to accommodate sub-0°C switch-ons – operation is over -40 to +85°C.

“Acetone cooling will become an option for the conga-TC675 and conga-TC675r,” the company told Electronics Weekly. “Most likely, they can be ordered off-the-shelf by Q3 – the acetone coolers themselves are currently in production.”

Heat-pipe coolers are in the pipeline for other modules – the company has mentioned form factors including COM-HPC Mini, COM-HPC Client and COM-HPC Server.


Applications are envisaged in logistics vehicles in ports, airports and cold stores, and in rail transport and aviation.
