3.7.2 Heat Exchanger Library
The new Heat Exchanger Library is targeted to heat exchanger design, dimensioning and
stacking. The library contains flat tube heat exchanger models supporting several flat tube
and louvered fin designs. The models accounts for effects of inhomogeneous air flow and
temperature distribution and it is possible to model heat exchanger stacking along the flow
path.
The library is suitable for studying the effects of heat exchanger dimensioning and
positioning on cooling performance. The library has a native interface to the Liquid Cooling
Library for complete thermal management design. The models can be coupled to
Computational fluid dynamics (CFD)-derived boundary conditions on the air side, bridging
the gap between CFD and system simulations.
The main focus is modeling of radiators and stacks in automotive applications.
Highlight features of the library are:
• Geometry based heat exchanger models for system simulations.
• Friction and heat transfer models for louvered fin designs.
• Captures effects of inhomogeneously distributed inlet air flow.
• Coupling to Computational fluid dynamics (CFD) data.
• Modeling of heat exchanger stacks with different heat exchanger geometries, sizes and
positioning.

3.7.3 Modelica_DeviceDrivers
The Modelica_DeviceDrivers Library allows accessing some external devices in Modelica
models. Such external devices are input devices, communication devices, shared memory,
analog-digital converters and else. This is achieved by using the Modelica external C
interface to call the appropriate C driver functions provided by the underlying operating
system. Currently Microsoft Windows and Linux are supported.
This Modelica package is free software.
