For the best use of an air stream, filling on the car during its motion, we should produce ventilation installation with the noncoverage of the heat sink by its shroud. Thus efficiency of installation decreases and we can see some air recirculation from under the bonnet area towards the radiator enclosure and, hence, system effectiveness of cooling decreases too. There are many recommendations on aspect ratio of a free part of the heat sink and enveloped by the shroud, but all of them do not consider aerodynamic resistance of the heat sink and resistance of an air-slaked section of the integral cooling system at all. The new technique that we offered in order to determine optimum order of covering by the radiator shroud is set forth below.
