Determination of rolling forces of corrugated profiles on stainless belt of heat exchanger for wind tunnels
The efficiency of regenerative heat exchangers with heat storage nozzles made of rolled corrugated
tapes depends on the type of their corrugation profile. The most effective form is a triangular one
with sharp peaks and troughs. It is technically advisable to get corrugations of a given shape by rolling
between two rollers. Determining the required contact load and forces is one of the main tasks when
rolling corrugated belts. Insufficient load leads to incomplete formation of the profile, and excessive
load leads to warping of the belt. The article presents the results of an experimental study aimed
at determining the required load when rolling a corrugated heat exchanger belt for wind tunnels.
Experiments and force measurements are carried out on a standard milling machine with a spring
dynamometer. The results of the experiment are applied to stainless steel strips with a thickness of
0,3 to 0,4 mm and triangular flutin
