Fluid inlet grille with aerodynamic grille bars

摘要

A fluid inlet grille ( 12 ) with aerodynamic grille bars ( 13 ) formed by leading grille bars ( 46 ) and trailing grille bars ( 47 ) separated by gaps ( 44 ). Each of the novel aerodynamic grille bars of the fluid inlet grille is constructed in such a manner that along a majority of its length its transverse cross section has a maximum width greater than its trailing edge width.
