Abstract
A method and a device of controlling the temperature of the coolant in a heat source of variable thermal yield, for example, a water-cooled internal combustion engine (1), in which the cooling circuit comprises a heat exchanger (2) communicating with the heat source through a supply duct (3) and a return duct (4) and a by-pass duct (5) arranged parallel thereto between the supply duct (3) and the return duct (4), wherein depending on the temperature difference of the coolant in the supply duct (3) or by-pass duct (5) and the return duct (4) as well as on the absolute temperature values thereof such a volume of coolant is passed through the heat exchanger (2) that a new state of equilibrium is produced in which the temperature in the supply duct (3) has dropped at an increase in heat production, in order to obtain a temperature decreasing tendency, that is to say, at a low load the coolant temperature in the engine is at a level which is higher than the required at full load.
