Information
This model represents a conventional vehicle cooler or heat exchanger. The model is based on a cross heat exchanger architecture. Two mediums are defined: the inner and the outer medium. As the inner medium it is best to use a medium in liquid state such as water or oil and as the outer medium it is most advantageous to use air. The inner medium doesn't necessarely have to be a liquid. The model basically is physically modelled. Only the pressure losses of the inner and outer medium are implemented with characteristic curves.
