Heat Exchanger Stacks
Heat exchanger stacks are a key coupling point between fluid circuits. The Heat Exchanger Library provides detailed, geometry-based models that can be stacked using a stream-tube approach for the airflow. This preserves non-uniform conditions for each heat exchanger in the stack.
Heat exchanger models in the library accept both uniform and non-uniform airflow inputs. This formulation is efficient enough to support drive-cycle work for a reasonable number of stream tubes.
Check out the technical paper Integrated Vehicle Thermal Management in Modelica, where results from heat exchanger stack simulations support cooling pack concept assessment.

Heat exchanger dimensioning and design
The Heat Exchanger Library, including a wide variety of heat exchanger models, is our reference tool for heat exchangers design. Testbenches are readily available, reducing both modelling time and simulation setup time.
Active grill shutters
The Heat Exchanger Library is the right tool for the development of control strategies for active grill shutters.
Heat exchangers are often the physical boundary between a fluid circuit and the ambient air. This implies that their performance affects the underlying system efficiency but also has consequences on the air side. This trade-off is most apparent in the automotive industry where a reduced air intake, by closing grill shutters, reduces the vehicle’s drag coefficient. The Heat Exchanger Library permits the study of this interaction, since the heat exchangers can be coupled to CFD results on one side and a system model on the other.
Intercoolers are a key element to improve the volumetric efficiency of combustion engines. The Heat Exchanger Library contains a wide set of application-specific models, which can be easily parameterized to represent your air-to liquid intercoolers or charge air coolers.
The Heat Exchanger Library is used in all applications that require detailed heat exchanger models.
