Line of sight blocking grille assembly

Abstract

A grille assembly having a housing including a corridor between a first end and a second end of the housing. The housing may be fluidly couple with a duct. The grille assembly also includes a core disposed within the corridor and having a plurality of blades that may guide fluid flow through the housing and a first portion of the plurality of blades slanted in a first direction at a first non-perpendicular angle relative to a corridor axis. The first portion of the plurality of blades are spaced relative to one another to form a first plurality of channels that partially pass through the housing. The grille assembly also includes a second portion of the plurality of blades slanted in a second direction that is substantially opposite the first direction at a second non-perpendicular angle relative to the corridor axis. The second portion of the plurality of blades are spaced relative to one another to form a second plurality of channels that partially pass through the housing and the first and second plurality of channels are arranged such that a line of sight from the first end to the second end of the housing is obstructed.
