This paper presents
a set of parametric studies of heat dissipation performed on automotive radiators.
The work’s first step consists of designing five radiators with different fin
pitch wave distance (P = 2.5, 2.4, 2.3, 2.2, 2.1 mm). Then, we proceed to the
fabrication of our five samples. The purpose of this work is to determine
through our experiment’s results which one have the best cooling performance.
This numerical tool has been previously verified and validated using a wide
experimental data bank. The analysis focuses on the cooling performance for
automobile radiator by changing several dimensions of the radiator fin phase as
well as the importance of coolant flow lay-out on the radiator global
performance. This experience has been performed at Hubei Radiatech Auto Cooling
System Co., Ltd. For the cooling performance experience, we use JB2293-1978
Wind Tunnel Test Method for Automobile and Tractor Radiators. The test bench
system is a continuous air suction type wind tunnel; collection and control of
operating condition parameters can be done automatically by the computer via
the preset program, and also can be done by the user manually. The results show
that the more we increase the fin phase, the better the cooling performance will
be and we also save material so the product cost will be cheaper.
