This mechanical device intended to improve the heat transfer and implementing the fouling of the heat exchangers

摘要

1. A heat exchanger comprising a plurality of tubes (1) in which a fluid circulates and in at least one of which is disposed a movable element formed by a metal coil in the form of a solenoid, at least one end of which is held in position by a coupling system such that said movable element can be caused to rotate by the fluid so as to prevent said tube from becoming clogged and to improve heat transfer, said exchanger being characterised in that said movable element (2) in the form of a solenoid is rigid and non-deformable so that it can be caused to rotate without coming into contact with the inner wall of said tube (1) during its movement, while said coupling system comprises an outer fastening means to said exchanger tube and a mechanical connection (4) enabling said movable element to rotate freely on its own axis, about the axis of said exchanger tube.
