The invention relates to a coolant circuit (5, 6, 7, 7a, 8, 8a), preferably for cooling a drive or an engine (2) of a motor vehicle (1), in particular of a passenger car, comprising: a controller (8) which, in order to control the temperature of a cooling fluid (7a), activates an electrically operated fan motor (5). The controller (8) is in thermal contact with the cooling fluid (7a) in order to be cooled and is formed to detect the temperature of the cooling fluid (7a) by way of a temperature sensor (8a) which is preferably provided at the controller (8). A defined temperature of the cooling fluid (7a) can thereby be set without a control signal from a master control or regulating device being required for this purpose.
Coolant circuit (5, 6, 7, 7a, 8, 8a), preferably for cooling a drive or an engine (2) of a motor vehicle (1), in particular of a passenger car, comprising:
Coolant circuit according to any one of the preceding Claims, in which the controller (8) is in thermal contact with a cooler (3) for cooling the cooling fluid (7a).
Motor vehicle (1) with a coolant circuit (5, 6, 7, 7a, 8, 8a) according to any one of the preceding Claims for cooling its internal combustion engine (2).
Coolant conduit (7) for a coolant circuit (5, 6, 7, 7a, 8, 8a) of a motor vehicle (1) which comprises a controller (8), in particular a linear controller, with a temperature sensor (8a) for determining the temperature of a cooling fluid (7a) flowing through the coolant conduit (3) during operation.
Cooler (3) for a coolant circuit (5, 6, 7, 7a, 8, 8a) of a motor vehicle (1) which comprises a controller (8), in particular a linear controller, connected thereto in a detachable manner, with a temperature sensor (8a) for determining the temperature of a cooling fluid (7a) flowing through the cooler (3) during operation.
