Wire heat exchange intensifiers (turbulence stimulators)

Wire heat exchange intensifiers (turbulence stimulators) are inserts placed in the heat exchange pipes of the air cooling unit along the entire length of the pipes. Wire heat exchange intensifiers has a periodic twisted spatial structure of loops made of round or other cross-section wire. The loop structure is held by several central core carrier wires.

The wire heat transfer intensifier is held in the pipe due to the elasticity of the wire loops, as well as a special anchor located at its rear end.

The mechanism of action of the intensifier is based on the turbulence of the fluid flow around the wire loops. Thus, the flow is mixed and the thickness of the near-wall boundary layer, which is the main resistance to heat transfer from the fluid flow to the pipe wall, decreases.

Wire heat transfer intensifiers are characterized by various shapes, sizes, inclination and frequency of loops, and the diameter and material of the wire for the manufacture of intensifiers are also selected for specific operating conditions.

The selection of the type of intensifier for specific operating conditions is carried out according to empirical dependencies obtained on an experimental bench.
