Heat Exchanger Calculator
Calculate the right heat exchanger size for your application. Understand how flow rates, temperature differences, and materials affect heat transfer requirements.
Step 1: Hot Side Parameters
Understanding Heat Exchanger Sizing
Proper heat exchanger sizing ensures efficient heat transfer. Undersized exchangers won’t meet thermal requirements, while oversized ones waste material and increase costs. The calculation considers flow rates, temperature differences, and fluid properties.
Step 2: Cold Side Parameters
About Heat Transfer Coefficients
The overall heat transfer coefficient (U) depends on fluid properties, flow rates, and exchanger design. Typical values range from 300-1200 W/m²K for liquid-to-liquid systems and 10-300 W/m²K for gas-to-gas systems.

Heat Transfer Analysis
Heat Exchanger Calculation Formula
Q = m × Cp × ΔT | A = Q / (U × LMTD)
The heat exchanger area is calculated using the heat transfer equation. Q represents heat duty, m is mass flow rate, Cp is specific heat capacity, ΔT is temperature difference, U is overall heat transfer coefficient, and LMTD is log mean temperature difference.
