Definitions
- the subject of the invention is a ventilation device for a motor vehicle.
- the invention relates to the automotive field, 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 designated by the term “ fins "or” dividers ".
- 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 towards the tubes and the fins.
- a ventilation device comprises a propeller fan.
- the air flow generated by the blades of such a fan is turbulent, in particular due to the circular geometry of the propeller, and generally only reaches part of the surface of the heat exchanger ( circular area of the exchanger facing the fan propeller).
- the heat exchange therefore does not take place uniformly over the entire surface of the tubes and fins.
- the blades when switching on the fan is not necessary (typically when exchanging heat with ambient air not accelerated is sufficient to cool the heat transfer fluid circulating in the exchanger), the blades partially obstruct the flow of ambient air towards the tubes and the fins, which hinders the air circulation towards the exchanger and thus limits heat exchange with the heat transfer fluid.
