- the invention relates to the field of the automobile, and more particularly to the field of air circulation for cooling the engine and its equipment.
- a motor vehicle heat exchanger generally comprises tubes, in which a heat transfer fluid is intended to circulate, in particular a liquid such as water, and heat exchange elements connected to these tubes, often referred to as “ fins "or" spacers ".
- the fins increase the exchange surface between the tubes and the ambient air.
- a ventilation device is used in addition, to generate or increase a flow of air directed to the tubes and the fins.
- Such a ventilation device most often comprises a propeller fan, which has several disadvantages.
- the assembly formed by the propeller fan and its motorization device occupies a large volume.
- the distribution of the air vented by the propeller is not homogeneous over the entire surface of the heat exchanger.
