Cooling Fan and System Performance and Efficiency Improvements. Reporting Period: June 1, 2002-July 31, 2005

摘要

This report contains six tasks. They are: Develop an axial fan that will provide more airflow, with less input power and less noise; Develop for chine use, an 'aseroshroud' concept developed at Michigan State University; Improve the axial fan system modeling process accuracy to accommodate the numbers of cooling systems to be redesigned to meet lower emissions requirements; Demonstrate the performance and design versatility of a high performance fan; Develop a high efficiency variable speed fan drive to replace existing slipping clutch style fan drives; and Develop a cooling system air filtration device to allow the use of automotive style high performance heat exchangers currently in off road machines.
