Optimization Calculation of Fin Height of Plate Fin Type Heat Transfer Element Used in Air Cooler
To study how heat transfer and pressure drop were affected by fin height of plate fin type heat transfer element,in a specific cooling engineering,plate fin type air cooler and mathematics method were introduced. By computing and comparison we knew that when fin height was 14 mm,product of heat transfer coefficient and area in a single equipment was maximized and initial unit investment was reduced;when 22 mm,heat transfer coefficient per pressure drop in air side in a single equipment was maximized and operation cost was reduced. Fin height selection is related to initial investment and operation cost.
