High air flow fan tray bracket

A fan tray bracket comprising:

• a tray bracket inlet, said tray bracket inlet having tray bracket inlet coupling elements;
• a tray bracket outlet coupled to said tray bracket inlet, said tray bracket outlet having a body;
• a plurality of tray bracket outlet passages contiguous with said body, said plurality of tray bracket outlet passages being alienable with fan passages of at least one fan unit, wherein said tray bracket outlet passages and said fan passages provide low impedance to air flow and low noise;
• and attaching means contiguous with said body, said attaching means being manually demountably coupled to said tray bracket inlet coupling elements;
• wherein said body includes, a face, a back opposite thereof, a first end and a second end opposite thereof;
• and
• wherein said attaching means includes tabs defined in said first end and tab slots defined in said second end and at least one coupling element disposed on said back of said body.

A fan unit assembly comprising:

• a tray bracket outlet including tray bracket outlet passages configured to prevent finger sized objects from penetrating said tray bracket outlet passages and attaching means;
• a tray bracket inlet demountably coupled to said tray bracket outlet without the use of tools;
• a first side demountably coupled to said tray bracket outlet without the use of tools;
• a second side contiguous with said tray bracket inlet;
• and
• at least one fan unit enclosed within said tray bracket outlet, said tray bracket, said first side and said second side, said at least one fan unit including fan passages, wherein said tray bracket outlet passages align with said fan passages minimizing air flow impedance;
• wherein said first side is a printed circuit board.
