Abstract

An arrangement for a supercharged combustion engine for preventing ice formation in a cooler. A first cooling system with a circulating coolant. A second cooling system with a circulating coolant which during normal operation of the combustion engine is at a lower temperature than the coolant in the first cooling system. The cooler in which a gaseous medium for the engine and which contains water vapor is intended to be cooled by the coolant in the second cooling system. A heat exchanger. A valve which can be placed in a first position wherein coolant from at least one of the cooling systems is prevented from flowing through the heat exchanger and in a second position wherein coolant from both of the cooling systems flows through the heat exchanger so that the coolant in the second cooling system is warmed by the coolant in the first cooling system.
