Abstract

A thermal management method for operating a thermal management system of an internal combustion engine. The thermal management system comprises at least one fluid chamber which is arranged at least partially around a cylinder head of a cylinder of the internal combustion engine and has at least one inlet line and at least one outlet line, the fluid chamber being connected to at least one coolant pumping device for pumping a coolant, and to at least one heat sink. According to a thermal management method, with increasing temperature of the at least one fluid chamber after a warm-up phase at a constant or decreasing engine speed, the coolant flow rate is temporarily increased through the at least one heat sink. At a constant engine speed or at an engine speed increasing at maximum 100 revolutions per minute and with reducing engine load, the coolant flow rate is maintained or increased through the at least one heat sink after the load change within a temperature range of 60° C. to 100° C. of the at least one fluid chamber
