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.]
