Air Cooler Fin tubes - Minimum Thickness of fins
Air Cooler Fin tubes - Minimum Thickness of fins
(OP)
We are using CS tubes with extruded type aluminum fins for Air Coolers. Our specifications for tube are:
Tube: OD 1", 14BWG, CS
Fin: OD 2 1/4", Pitch 3.175mm, thickness at crest 0.2-0.3mm, Aluminum B221-6063-0
Some suppliers are quoting for fin thickness of 0.4mm.
May i cross reference the quoted thickness with some material / design standard or should i remain firm with design specifications?

While the OP's fin pitch is seemingly large, relative to the fin thickness, I don't know for certain that increasing the fin thickness won't decrease the overall heat transfer coefficient, since the added thickness is increasing the thermal conductivity of a component that potentially already has a decent thermal conductivity, while the reduced gap might noticeably drive down the convective heat transfer.
