Abstract
Investigations have been carried out as to whether cooling systems with tangential flow fans can be designed with the same noise, efficiency and package size as acoustically optimized cooling systems using axial flow fans.
Previous work had shown that cooling systems with commercially available tangential flow fans could not meet these requirements. In the case of low and wide radiator cores, however, the application of tangential flow fans appeared advantageous since the tangential flow fan is fully adaptable to the width of the radiator core.
For the main part of the development work an experimental tangential flow fan was used which permitted a wide range of modifications to be made and enabled the air flow to be observed.
Extensive development resulted in a compact cooling system with a radiator core located downstream close to the impeller and with characteristics coming up to expectations. The results obtained could also be confirmed on a cooling system designed for a medium class passenger car.
