2020.1 Release Notes – Heat Exchanger Library 2.5

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.
