PowerCOOL® is used to model heat exchangers such as automotive radiators or charge air coolers. It is invoked by a PowerFLOW® simulation in a coupled mode to predict the heat transferred between the airflow, calculated by PowerFLOW, and a heat exchanger. The result is provided either as the temperature of the coolant at the inlet of the heat exchanger (top tank temperature) or the heat rejection. Users choose between these two options based on design goals and available data. Other results include distribution of air parameters like velocity, temperature and density on the surface of the heat exchanger and coolant temperature distribution within the heat exchanger. These results provide essential information needed for positioning heat exchangers, understanding their operation and optimizing the overall underhood design of the vehicle.
FEATURES / BENEFITS
Accurate calculation of the heat transfer between the heat exchanger and the cooling airflow
Seamless integration into PowerFLOW workflow
HOW DOES IT WORK?
Airflow in the underhood area of a vehicle is the primary source of engine cooling. A quick look at the vehicle underhood reveals exceptionally complex geometry. In addition to the engine, there is a radiator, condenser, one or more fans and other heat exchangers and components. The airflow needs to have adequate access to all relevant parts that require cooling. Due to complex geometry, ensuring sufficient air cooling is not necessarily simple. Air entering from the front grille is affected by many components as it travels through the underhood. Even small geometric details affect the flow direction and can easily cause recirculation regions that reduce the cooling efficiency. Therefore, air cooling flow analysis requires detailed treatment of the underhood geometry, and at the same time, accurate airflow modeling. The figures below show the geometry of two car simulations where PowerCOOL is used to model heat exchangers.
