Due to good energy-efficiency of electrohydraulic compact drives a cooling aggregate often is not installed. The prevailing operating temperature is governed by the complex interaction between dissipative heat input and passive heat output. This paper highlights the simulation of the thermo-energetic behaviour of an electrohydraulic compact drive by means of a lumped parameter model in order to predict the operating temperature. The developed thermo-hydraulic model is validated against measurements utilising thermo-elements and a thermographic camera to capture temperature. It shows that the thermo-energetic behaviour of the demonstrator is predicted sufficiently precise in order to support development, optimisation and examination of possible fields of application of electrohydraulic compact drives.
