Abstract
A heat exchanger includes a fluid flow passage with a wavy fin turbulizer. The turbulizer includes sidewalls extending lengthwise along a fluid flow direction between its first and second ends, and the sidewalls are spaced apart across the width of the turbulizer. Each flow channel of the turbulizer is defined between two adjacent sidewalls. Each sidewall has a smoothly and continuously curved profile with repeating wave forms being defined along the length of the turbulizer. The continuously curved profile of the sidewalls is defined by a non-circular shape, such as elliptical, sinusoidal, parabolic and hyperbolic shapes. The radius of curvature changes constantly and reaches a maximum at or near the inflection point between adjacent crests and troughs of the profile, to provide improved particle pass-through, lower pressure drop, and enhanced plateability of internal surfaces.
