Aluminum plate-fin heat exchanger selection method?

Exchange of heat Q (kW); oil inlet temperature T1 (° C); oil outlet temperature T2 (° C);
Volume flow rate W (m3 / h); fluid density ρ (kg/m3); fluid specific heat at constant pressure Cp (KJ / kg of x ° C);
Cold inlet temperature: t
① System Cooling general formula (simplified):
Q = 0.000278 * W * ρ * | T1-T2 | * Cp
② than the heat dissipation
q = Q / (T1-t)
The ③ required heat
Q '= q * 30
The point of intersection where the performance according to the calculated heat dissipation q (or the required heat Q ') as well as the performance curve by cooler oil flow from the Division I introduced the book was found in two parameters, coordinates curve, the curve corresponding to the product model for the divinity of your company the desired product model. The above method for the general selection method. When due to actual conditions on the cooler and have higher expectations, such as lower oil temperature, oil-containing impurities, poor water quality can not be introduction to the book directly from product selection, please contact with us and use the parameter list, the Secretary may provide selection services.
