Content
In order to maximize the cooling performance of road vehicles one must be familiar with and understand the behavior and character of the underhood flow system. Critical features, such as bottle necks, must be isolated and modified in order to improve the performance. The underhood flow system can be thought of as a network of subsystems, among which no one can be neglected since they are all, in some way, linked. This paper describes the general character of the cooling airflow on Scania heavy trucks. The variation of installation parameters and studies of different design concepts reveals the sensitivity and complexity of the cooling airflow. The results indicate, among other things, that the depth and also the shape of the fan shroud are of great importance. From the results also the influence from flow uniformity on the pressure loss and cooling capacity is obtained.
