The invention relates to a thermal control system () for a vehicle, the thermal control system () comprising at least one first heat exchanger () and at least one second heat exchanger () that are arranged in series, the first heat exchanger () extending mainly on a first plane (P) intersecting a second plane (P) on which the second heat exchanger () mainly extends such that the first heat exchanger () is closer to the second heat exchanger () at respective first ends () of the two heat exchangers () and the first heat exchanger () is farther away from the second heat exchanger () at respective second ends () of these two heat exchangers ().

Temperature control system for a motor vehicle

The invention relates to a condenser () to be used in an air-conditioning circuit of an automobile, including punched plates () stacked in a longitudinal direction and defining first blades for the circulation of a first fluid as well as second blades for the circulation of a second fluid, said second blades being interleaved with the first blades, said condenser enabling the alternating circulation of the first fluid. According to the invention, said condenser includes inlet tubing () for the first fluid and outlet tubing () for the first fluid provided on a single first end surface () of said stack.

The pumps of the high- and low-temperature circuit form first actuators for running the heat carrier fluid though the circuits and second actuators for flowing the cooling fluids in the high- and low-temperature radiators, and sensors for detecting representative parameters of the cooling requirements of the high- and low-temperature circuits and for transmitting said parameters to a control unit. The transmitted parameters include at least one parameter related to the first actuators and at least one parameter related to the second actuators. The control unit adjusts the first and second actuators according to these parameters.

The device comprises a main loop ( ) for cooling the fuel cell ( ) and a secondary loop ( ) for cooling at least the motor ( ). These two loops ( ) form part of the same circuit which is traversed by a single refrigerant fluid and which comprises a section ( ) common to the two loops on which a common pump ( ) is mounted, and at least one regulation valve ( ) is provided which is suitable for sharing the refrigerant fluid between the loops ( ) according to a chosen law. Application to electric and hybrid vehicles.

Device for cooling a vehicle with an electric motor powered by a fuel cell

The cooling circuit of an internal combustion engine of a vehicle includes a thermally insulated reservoir having an inlet duct and an outlet duct. These ducts are connected to the mass of air in a head space either within the expansion vessel in the cooling circuit or within the reservoir itself, in such a way that the inlet and outlet ducts become filled with air when the motor is stopped. This air then physically separates the liquid in the reservoir from that contained in the rest of the circuit, so reducing heat losses.
