  • Steady state investigations of a cooling system including an indirect charge air cooler (CCFC)

  • KULI-System

    Due to constructive and performance reasons, indirect charge air coolers are more frequently used in state of the art cooling systems. Therefore this example demonstrates how a CCFC can easily be included in a steady state simulation model, whereby a low temperature radiator is added in the frontend and the coolant cooled cross-counter flow cooler (CCFC) is mounted next to the engine.

    The KULI file shows the simulation model of a passenger car, including the main cooling circuit with the heat input of the engine, a simplified oil circuit and both sides of the indirect charge air circuit.

    The CCFC is based on measurement values and geometrical input, therefore the data input differs from the traditional charge air cooler. At first, the user has to set up the geometrical properties and the configuration of the layers. In a next step, the measurement data defining the heat transfer and the pressure loss must be entered. The data can be input in a single table (no need for additional cold measurements of the pressure loss). To use this data, a calibration is obligatory. For the best result, the user can choose between different calibration methods like linear, quadratic or cubic.

    The calibrated CCFC is included in the charge air circuit (outer side) and in a low temperature coolant circuit, which is located in front of the main radiator.
