AI Technical Summary

Technical Problem

Existing air inlets in motor vehicle engine compartments have fixed dimensions, leading to uncontrolled cooling airflow rates and temperatures, which can result in excessive cooling of components, increased aerodynamic drag, and potential injury risks during pedestrian collisions due to rigid air guide edges.

Method used

An air guide with a rounded upper front edge and flexible deformation zones, featuring a circular arc profile and elastomeric materials, designed to deform in pedestrian collisions, combined with a controlled regulation module for airflow, reduces injury risks and improves airflow control.

Benefits of technology

The air guide effectively reduces the risk of pedestrian injuries and optimizes cooling airflow by allowing controlled regulation and deformation in collisions, while maintaining aerodynamic efficiency.

Abstract

The invention relates to an air guide (110) for a cooling device (100) intended to be permanently installed in the engine compartment of a motor vehicle between the front bumper and the cooling cassette (10) of that vehicle, said air guide (110) comprising a hollow main body of substantially parallelepiped shape (111) including a front face (112) bordered by a peripheral frame (113) extending behind the latter, said front face (112) having at least one passage window formed in its lower part and intended to be opposite a controlled incoming airflow regulation module (120); characterized in that the upper front edge (117) of said main body (111), connecting the front face (112) to the upper wall of the peripheral frame (113), has a rounded arc-shaped profile in cross-section.
