Abstract

Heat exchanger is widely used in the vehicle cooling system and its performance influences the vehicle dynamic performance significantly. In present paper, an object-oriented louver fin-and-tube heat exchanger model was developed to simulate the dynamic outlet temperature of air and coolant. A two-dimensional discrete strategy, which divided the heat exchanger into macro control volumes on both air and coolant sides, was proposed. The mathematical model of each control volume on the air side, the coolant side and the wall was presented based on some reasonable assumption. The model was developed in the object-oriented language Modelica based on such two-dimensional discretization. The results of simulation were validated using a set of experimental data.
