A disclosed thermal management system includes a radiator for cooling coolant fluid, and a coolant pump for circulating coolant fluid received from the radiator. A set of conduits fluidly connect the coolant pump to an engine block, a cylinder head, and an exhaust manifold. Another set of conduits fluidly connect the engine block, cylinder head, and exhaust manifold to the radiator, coolant pump, and one or more oil heaters. A first valve assembly is operable to regulate coolant flow between the coolant pump and the radiator. A second valve assembly is operable to regulate coolant fluid flow, individually and jointly, between the engine block, cylinder head, exhaust manifold, radiator, coolant pump, and oil heater(s).

A thermal management system includes a transmission, a heat exchanger, and a transmission control unit. The transmission includes: a transmission housing; a transmission pan housed within the transmission housing; transmission fluid contained within the transmission pan; and a transmission fluid conduit configured to circulate the transmission fluid between the transmission pan and within the transmission housing. The heat exchanger is disposed within the transmission housing and has a first surface positioned on the transmission pan and a second surface. The transmission control unit is disposed on and supported by the second surface of the heat exchanger such that the heat exchanger controls the temperature of the transmission control unit.

A charging device module for installation in an electrically driveable vehicle, including a charging device and an internal cooling circuit for cooling the charging device, wherein the internal cooling circuit has connections for connection to a superordinate cooling circuit of the vehicle, wherein the connections comprise at least one inlet and at least one outlet, and a bypass line connects the at least one inlet to the at least one outlet while bypassing the internal cooling circuit, wherein an actuable valve is associated with the at least one inlet, by which valve the flow of coolant through the internal cooling circuit and the bypass line can be controlled.

The liquid cooling circuit is configured such that the movement of the coolant relative to the heat-generating module transfers heat from the heat-generating module to the coolant.

A temperature control apparatus of a vehicle according to the invention stops activating a heat pump and supplies heat exchanging liquid from an engine passage to a battery passage when a warming of the battery is requested and a temperature of the heat exchanging liquid flowing out of the engine passage is equal to or lower than a permitted upper limit temperature. On the other hand, the apparatus activates the heat pump to cool the heat exchanging liquid and supplies the cooled heat exchanging liquid from the engine passage to the battery passage when the warming of the battery is requested and the temperature of the heat exchanging liquid flowing out of the engine passage is higher than the permitted upper limit temperature.
