abstract = {The objective of this paper is to analyze the heat transfer
characteristics of plate-fin radiator for the cold air
heating system of a PEMFC engine and to find the optimal
parameter combination in order to reduce the power
consumption. The effect of the coolant mass flow and
temperature on the heat exchange performance of the radiator
was investigated based on 3D porous medium model. The
results, including the amount of heat transferred and
temperature change and heat exchanger effectivity with the
increasing of the air flow rate at different coolant flow
rate were obtained using CFD method. Good agreement is found
by comparing the simulation values with the test data and
the deviation is less than $7\%$ which indicate simulation
model validation and research method feasibility used in
this study. The simulation results indicate that bigger
coolant flow rate and temperature result in higher outlet
air temperature and the amount of heat transferred. The
variation of the heat exchanger effectivity is predicted for
different working conditions. Based on the Taguchi method,
the influence of structural parameters of the corrugated
fins on the heat transfer and pressure drop of the radiator
is analyzed qualitatively. It is shown that fin length has
the greatest impact on the comprehensive heat transfer
performance of the radiator. This research provides a guide
for optimizing the air preheating system and improving the
amount of heat transferred.},
