Heat Exchanger Library v2.5 is part of Modelon’s 2020.1 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.


  • Improved Modelica compliance for ph-Diagram scaling.
  • Detailed documentation on the parameterization of heat exchanger geometry has been added as a separate section in user’s guide for both flat tube and plate heat exchangers: Heat Exchanger Geometry Parameterization

Fixed issues

  • Removed the counterFlow parameter from geometry PlateSecondaryFinBase. This should be specified either in template or at example level using relativeFlowDirection parameter. This fixes the compilation issue with TwoPhaseFinLiquidFin HeatExchanger.


  • Heat Exchanger Library 2.5 is based on Modelon Base Library 3.4 and Modelica Standard Library 3.2.3.
