Abstract:
A duct particularity adapted for channeling a flow of cooling air to a heat sink of a processor of a personal computer, said duct comprising:a body having spaced apart sidewalls connected by an inner wall and an outer wall to define an interior passageway forming a S-like shaped flow path through said body, a lower section of said body having an enlarged bottom end formed with an intake opening in said outer wall and a narrow top end formed as said walls of said lower section extend upward while said sidewalls of said lower section converge inward with a cross section of said bottom end being substantially larger than a cross section of said narrow top end, and an upper section of said body having a narrow bottom end connecting with said narrow top end of said lower section with said inner wall of said upper section arching inward and said outer wall of said upper section diverging upward so that inner end edges of said walls of said upper section define an outlet opening having a cross section about twice as large as a cross section of said upper section narrow bottom end, wherein for use, said duct is placed inside an enclosure of said personal computer so that said intake opening of said duct is positioned adjacent to vent openings in a side panel of said enclosure and said outlet opening of said duct is positioned adjacent to said processor heat sink, and air being drawn into said enclosure through said vent openings flows directly through said duct interior passageway to said processor heat sink.
