Thermal Management Evolution and Controlled Coolant Flow 2001-01-1732

A tremendous amount of research has been done on the coolant system of engines, however, the configuration remains virtually the same since the early 1900's. Recent testing has shown that by controlling components such as thermostats and water pumps, efficiency and emission improvements can be realized. With the nearing of higher voltage and hybrid systems, along with the availability of high efficiency electric pumps and valves, we are fast approaching the implementation of controlled coolant flow technology. This paper will discuss the problems with the current cooling systems, some of the work that has been done recently and what an ideal controlled coolant system may look like in the future.
