Air Cooler Design Fundamentals: Geometry, Tubing, Fans, and Tradeoffs

By Shi Yintao · Technical Director ·

When you’d use an air cooler

[STUB — when ambient air is the practical heat sink; cost vs water; fouling vs cleaning.]

Bundle geometry: rows, pitch, and length

[STUB — row count vs ΔP; triangular vs square pitch; length aspect ratios.]

Tube selection

[STUB — round vs elliptical; finning options (G, L, KL, embedded); material choices and corrosion classes.]

Fan sizing

[STUB — forced vs induced draft; multi-fan failure planning; noise.]

The practical tradeoffs nobody talks about

[STUB — height vs footprint; fouling factor margins; field maintenance access.]
