Abstract

In this work, after the elevators shaped by NACA 0012 were proposed for the Flat-tube-and-fin heat exchanger (FTFHE) with an experimental validation, a signal-to-noise (SNR) analysis was considered for the contribution rate (CR) of structural parameters. It is found that, for CR, chord length dominates with 43,44 % as the minimum 13,11 % escort orientation point. Besides those, the mounted angle of 0°, the chord length of 6,4 mm, the extruded length of 1 mm or Orientation point 6 might only benefit heat transfer, while 8°, 6 mm or 0,9 mm purely serves pressure loss disregarding orientation point.
