  • the cooling element 7 may be a radiator configured according to methods well known in the art, e.g.
  • the bottom side of the cooling member 6 perpendicular to the general air flow direction 17 defines the air intake for the cooling member 6. Exceptions to this definition are found when the cooling member is mounted some distance from the upstream edge 15 of the exterior panel (shown in figure 9) or when the air intake is mounted in a raised roof section 12 extending past the windshield 3 (shown in figure 10).
  • This air intake 8 may be direct access to the air flow or a grille-type structure well- known in the art, which includes holes or slits in a cover plate.

  • Each cooling element 7 is placed at an angle 16 between the general air flow direction 17 and the general surface of the cooling element 7. The angle 16 may range from 1 to 179 degrees where this angle may be increased or decreased from 90 degrees to in- crease the area of the cooling element 7, while still maintaining the dimension perpendicular to the airflow.
  • cooling elements 7 are arranged according to the preferred embodiment to follow one another with respect to the air flow, i.e. the cooling elements 7 are placed in series relative to the general air flow 17. This is done in order to improve the cooling efficiency, by taking advantage of the residual cooling available after air has passed the first (with respect to the general air flow direction) cooling element 7 .
  • the cooling elements have different angles 16 to the general air flow direction to improve the fit behind a conven- tional sun visor design.
  • Another embodiment of the cooling element is shown in figure 5.
  • the cooling elements 7 are placed in parallel relative to the general air flow 17, which may in some instances provide better air flow and/or simpler thermal connectivity to the cooling elements 7.

Abstract

La présente invention concerne un véhicule, tel qu'un poids lourd, par exemple, un camion comportant une cabine (1)comprenant une partie avant (2) comprenant une pare-brise (3) et des zones périphériques (4), un toit (5), et un moyen de commande d'un système de refroidissement, ledit véhicule étant équipé d'au moins un organe de refroidissement auxiliaire (6) comprenant au moins un élément refroidisseur (7), et un orifice d'admission d'air (8), où au moins une partie de l'élément refroidisseur fait saillie depuis la face avant (2) pour utiliser au moins une partie du flux d'air global circulant sensiblement parallèle à la partie avant (2) lorsque le véhicule se déplace vers l'avant. Selon des modes de réalisation préférés, au moins un panneau extérieur (9) est monté pour recouvrir les éléments refroidisseurs (7) de l'organe refroidisseur (6), et il est préférable que ce panneau extérieur (9) soit une visière pare-soleil (10) ou un déflecteur de poussière (11). Ainsi, on obtient un refroidissement supplémentaire important sans modifier l'aspect global et la conception du camion permettant de maintenir les exigences de dimensions du véhicule.
