Abstract:
A vented cell structure, comprising:a first honeycomb layer comprising a plurality of first cell walls to define a plurality of first cells; a second honeycomb layer adjacent and connected to said first honeycomb layer and comprising a plurality of second cell walls to define a plurality of second cells, wherein said first honeycomb layer and said second honeycomb layer are positioned such that the plurality of first cells and the plurality of second cells are misaligned, wherein said first honeycomb layer is positioned at least partially in a separate plane than said second honeycomb layer, and wherein the first honeycomb layer and second honeycomb layer are connected only at intersections of the plurality of first cell walls and the plurality of second cell walls without other obstruction between said first honeycomb layer and said second honeycomb layer, such that fluid can flow without obstruction between the plurality of first cells and the plurality of second cells; and a structural layer on opposite sides of said first honeycomb layer and said second honeycomb layer, wherein said structural layer defines at least one opening aligned with at least one of the first cells and at least one of the second cells, to thereby create the vented cell structure, wherein the plurality of first cell walls of said first honeycomb layer define the plurality of first cells having a different shape and size than the plurality of second cells defined by the plurality of second cell walls of said second honeycomb layer.
