Function of the Q-dot Heatpipe

The thermal energy fed to the one face causes the heat transfer medium to vaporize. This vapor expands in the direction of the cold face where it condenses into a liquid, so producing heat from condensation.

The heat transfer medium which is now again in liquid form is then conveyed back via the capillary structure and / or by the effect of gravity to the starting point.

This cycle of vaporization and condensation is maintained solely by the difference in temperature between the two faces, without any other drive.

Q-dot Heatpipes are made from metal, have an internal capillary structure, are evacuated and filled with special heat transfer medium which is suitable for the relevant temperature range, and are hermetically sealed. The manufacturing processes were protected by numerous foreign and domestic patents till 1992.
