Fluid inlet grille with novel aerodynamic grill bars

摘要

A novel fluid inlet grille with novel aerodynamic grille bars is disclosed. 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 cross-section perpendicular to its longitudinal axis has a chord length that is greater than twice its maximum width, a maximum width that is greater than its trailing edge width, and is disposed such that its chord line is disposed at an angle of less than ten degrees to a prevailing direction of inflowing air.
