A cooling system for a motor vehicle, has a first cooling circuit arrangement with a first coolant cooler and a second coolant circuit arrangement with a second coolant cooler. A cooling air supply to the first coolant cooler can be varied by means of a first cover device, and a cooling air supply to the second coolant cooler can be varied by means of a second cover device. The first cover device and the second cover device can be moved by means of an interposed gear of a shared drive, whereby the gear is configured such that, when the drive is being operated for opening purposes, the second cover device is moved earlier and/or faster than the first cover device out of a closed position in the direction of an open position. This makes it possible to supply cooling air to meet an already existent cooling demand of the second coolant cooler, whereas such a cooling demand does not yet exist for the first coolant cooler, so that the latter can still remain covered—in terms of a flow of cooling air—by means of the associated (first) cover device. This can have a positive effect on the flow resistance for the cooling air and thus on the aerodynamics of the motor vehicle.

The thermal management system includes a cooling circuit in which cooling water circulates, a heat exchange circuit in which cooling water performing heat exchange with a battery flows, a flow rate control valve which adjusts a flow rate of cooling water flowing from the cooling circuit to the heat exchange circuit, a shutter which adjusts an introduction amount of outside air into an engine room, and an ECU which controls an opening degree of the flow rate control valve and an opening degree of the shutter. The ECU controls the shutter and the flow rate control valve to be in a fully closed state when a cooling water temperature is less than a valve opening temperature of a thermostat valve and controls the shutter and the flow rate control valve to be in an open state when the cooling water temperature is greater than the valve opening temperature.

A coolant thermoelectric generation system may include a thermoelectric module 20 connected to a high temperature line 13 through which engine coolant flows and a low temperature line 24 through which coolant having a temperature lower than a temperature of the engine coolant flows, and configured to perform thermoelectric generation with a heat exchange effect based on a coolant temperature difference between the engine coolant and the coolant having a temperature lower than a temperature of the engine coolant with a thermoelectric element 21 interposed therebetween; a heat exchange line 16, in which the heat exchange effect occurs, and a bypass line 17, in which no heat exchange effect occurs, the heat exchange line and the bypass line connected to the high temperature line to form two paths, respectively 13; and built-in valves 14, 14-1, 14-2 located in the internal space of the thermoelectric module, and configured to adjust flow rates of the coolant in the heat exchange line and the bypass line.

In a heat exchange unit, a shutter device is disposed on a vehicle front side with respect to a coolant heat exchanger to open and close a passage for traveling air directed toward the coolant heat exchanger. A blower is switchable between a first blowing state in which air flows from the vehicle front side to the vehicle rear side and a second blowing state in which air flows from the vehicle rear side to the vehicle front side. In a case where a switch that makes a vehicle travelable is in an on state, a control unit switches the blower to the second blowing state, while an open degree of the shutter device is set at a closing side from a maximum open degree of the shutter device when a temperature of the engine coolant is equal to or lower than a predetermined temperature determination value.
