Closure element for e.g. car, has rear part, and front part oriented towards vehicle`s front so that airflow enters in contact with surface, where parts with conical and hemi-spherical shapes are obtained by utilization of design molds

摘要

#CMT# #/CMT# The element has a vane (24) including a curved front part (30) that is oriented towards a front of a motor vehicle e.g. car, such that an airflow (8) initially enters in contact with a curved surface (31) of the front part, where the element is in the from of an air extraction grid. A tapered rear part (40) has a conical shape extending the front part towards the vehicle`s rear such that the vane has water drop shape. The parts are connected to one another, where the parts with conical revolution shape and hemi-spherical revolution shape (33) are obtained by utilization of simple design molds. #CMT#USE : #/CMT# Used for being positioned in front of an opening of an air extraction device that is utilized for being arranged in a rear wheel housing formed in a left front wing of a motor vehicle (claimed) e.g. car (from drawings) to permit a non turbulent passage of air flow from the front to the rear of the vehicle. #CMT#ADVANTAGE : #/CMT# The curved front part and the tapered rear part of the vanes with respective conical and hemi-spherical revolution shapes are obtained by the utilization of simple design molds, thus easily obtaining the aerodynamic and acoustic gain of the device. The element ensures the cooling of an engine and permits to secure the access of an engine compartment from an exterior while permitting the passage of air. The curved front part is oriented towards the front of the motor vehicle such that the airflow initially enters in contact with the curved surface of the front part, thus minimizing the deflection of airflow with respect to its direction. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an air extraction device. 8 : Airflow 24 : Vane 30 : Curved front part 31 : Curved surface 33 : Hemi-spherical revolution shape 40 : Tapered rear part.
