ABSTRACT
This thesis documents the testing, design and analysis performed to determine the optimal design for the 2007 cooling system for the University of Toronto Formula SAE race car. The main focus of this project is the physical testing and analysis of the data collected. The cooling system design has been refined as a result of the testing carried out in this project. The test data has been analyzed to identify heat rejection requirements, optimal engine operating temperature, and other important design parameters. It has been found that the cooling system used in the race car must reject 9500 Watts of heat energy, and should aim to maintain an operating temperature of 85°C. The 2007 cooling system promises to be successful and an improvement over last years system. The new system is 10% lighter than the system it replaces, contributing to the overall improvement of vehicle performance of the 2007 University of Toronto FSAE race car.
