Thermal management

Thermal management ensures the targeted utilization of heat generated during motor vehicle operation and the demand-oriented redeployment of this heat thereby associated with it. To make this possible, all heat sources and sinks, as well as their time-dependent cooling/heating requirements must be known. 

 

A main objective of thermal management is ensuring the cooling capacity. This is needed for conducting heat away from the affected components and the passenger area. Another objective is the productive utilization of all available heat sources for energy savings.

 

For example, through targeted thermal management measures as the vehicle warms up, the friction in the power train can be decreased and therefore fuel consumption can be reduced. Especially at low ambient temperatures, the interior comfort of the passengers is an important criterion, since the heat required to heat up the passenger area has to be drawn from the cooling system.

 

The three most important tasks of thermal management are:

 

In thermal management, too, numerical simulation provides important support for the development process. Cooling systems are designed and optimized at FKFS using 1D simulation tools, which were specifically developed for hydraulic and heat transfer applications.
