Abstract
A turbulence agitator placed, for example, in the tube of a heat exchanger, comprises at least one continuous helical thread. The section through the agitator in any plane passing through the axis of the helix has a central portion and teeth of the same shape and dimensions, spaced along the said axis. Each of these teeth is asymmetrical in relation to a line perpendicular to the axis of the helix.
