Abstract
The invention concerns an engine cooling system that comprises a cooling circuit () and an evaporative cooling arrangement (). The cooling circuit () has a cooling capacity provided by exchanging the heat generated by the engine with ambient air. The evaporative cooling arrangement () has a cooling capacity provided by dissipating the heat generated by the engine, by vaporization of a vaporizing coolant in a boiler. The cooling capacity of the evaporative cooling arrangement () is such that with the cooling capacity of the cooling circuit (), the global capacity of the cooling system can match, at least peak, cooling demands. As the cooling capacity of the cooling system is divided between the capacity of the cooling circuit and the capacity of the evaporative cooling arrangement, the capacity of the cooling circuit can be reduced in comparison to a conventional cooling circuit which has to match alone peak cooling demands.
