The invention relates to a system () for cooling at least one motor vehicle battery (), this system including:

System for cooling at least one motor vehicle battery

The invention concerns a device () for controlling an air flow (F) circulating in a first heat exchanger () for a motor vehicle comprising at least two screens (), the control device () being configured to go from a closed configuration in which the screens () obstruct the passage of the air flow (F) completely to an open configuration in which the screens () are positioned in such a manner as to allow the air flow (F) to pass with a maximum flow rate, and any intermediate configuration. According to the invention, the two screens () are adapted to be moved away from one another when the control device () goes from the closed configuration to the open configuration and to be moved toward one another when the control device () goes from the open configuration to the closed configuration.

Device for controlling an air flow

The invention relates to a heat exchanger (), especially an exchanger for the air-conditioning system of a vehicle, allowing heat exchange between first (F) and second (F) fluids, said exchanger () comprising a plurality of tubes () for the circulation of the first fluid (F), which are stacked one on top of the other, and at least one collector () comprising a collector plate (), said collector plate () comprising openings () for inserting the ends () of tubes (), characterized in that said ends () of said () are assembled at least two by two in the insertion openings of the collector plate ().

Heat exchanger for motor vehicle

A heat exchanger () comprises an alternating stacking of first plates () and second plates () provided respectively with first corrugations () separated by a first pitch (P) and second corrugations () separated by a second pitch (P), which is different from the first pitch (P). Between the plates, first flow channels are defined having a first cross sectional area adapted to a first fluid (F) which alternate with second flow channels having a second cross sectional area adapted to a second fluid (F). The invention applies in particular to heat exchangers for motor vehicles.

Plate-type heat exchanger, particularly for motor vehicles

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.

Automobile condenser having enhanced integration

A control valve for a cooling circuit of an automobile engine comprises a valve body () provided with an input () and a number of outputs () for a coolant, an adjustment member () designed to rotate about a rotation axis (XX), an electric motor () coupled to the adjustment member () to bring it into chosen angular positions to control the distribution of the coolant between the outputs (), and an absolute position sensor () coupled in rotation to the adjustment member () to deliver an output signal (S) representative of the angular position of the adjustment member (), wherein the motor is able to be driven by a position controller (CP) which is designed to receive the output signal (S) and which is used to adjust the angular position of the adjustment member ().
