TURBULISING UNIT FOR HEAT EXCHANGING PIPE Russian patent published in 2009 - IPC F28F13/12 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering, namely to the turbulising unit design and can be used in different heat exchanging pipes of industrial heat exchangers. The turbulising unit for a heat exchanging pipe comprises swirling blades which are streamlined by the heat carrier flow and are rigidly fixed on the axis with the specified interval, the axis is made as two intertwisted rods and the swirling blades are made as rectangular plates mounted between the twisted rods and set along the pipe length with the interval of 0.5-5 inner pipe diametres. The twisting value changes the rotation angle of the plate plane in respect to the heat carrier flow by 1-15 grad and the rotation angle of the swirling blades in respect to each other by 15-90 grad.

EFFECT: optimal intensification of heat exchange in the heat exchanging pipes with different operation modes is achieved during a short period of time and without great expenditures.
