Patent ID: 8829795

Claim:
An axial-flow fan assembly having a turbine type enclosure, comprising: a first heat dissipation structure ( 102 ) positioned at a top of a heat source housing ( 101 ) for receiving external heat energy from the heat source housing ( 101 ); an annular arc-shaped guide plate ( 103 ) extending around a periphery of the heat dissipation structure ( 102 ); an electric axial-flow fan ( 202 ) installed adjacent a top portion ( 104 ) of the heat dissipation structure ( 102 ), said annular arcuate guide plate ( 103 ) extending around a bottom of the electric axial-flow fan ( 202 ), said electric axial-flow fan ( 202 ) including a fastening seat ( 106 ) installed at a top of the axial-flow fan ( 202 ); a fastening core shaft ( 206 ) installed at a center of and extending upwardly from the fastening seat ( 106 ) at the top of the axial-flow fan ( 202 ); radially-arranged exhaust blades ( 207 ) mounted to the fastening core shaft ( 206 ) and rotatable in response to upward flow of a fluid pumped by the axial-flow fan ( 202 ) in an axially upward direction, the rotating exhaust blades ( 207 ) directing the upwardly flowing fluid pumped by the axial-flow fan in a radially outward direction towards an exterior of the turbine type enclosure; a flow guide cone ( 107 ) within the sealed top cover ( 209 ) and combined with tops of the radially-arranged exhaust blades ( 207 ); and an annular axial fluid inlet port ( 208 ) at a bottom of the axial-flow fan ( 202 ) and extending between the heat dissipation structure ( 102 ) and the annular arc-shaped guide plate ( 103 ) to guide the fluid in a radially inward direction from the exterior of the turbine type enclosure past the heat dissipation structure ( 102 ) to the axial-flow fan, said axial-flow fan pumping the fluid in said axially upward direction to the radially-arranged exhaust blades ( 207 ), and the radially-arranged exhaust blades ( 207 ) directing the pumped fluid in said radially outward direction back to the exterior of the turbine type enclosure.
