Abstract: A heat dissipating system of a personal computer has a heat dissipating unit; the heat dissipating unit including a power supply; the power supply including a housing and a cover; a circuit and a double suction turbine fan being placed in a space formed by the housing and cover; the double suction turbine fan having a casing and a set of blades; an upper and lower surface of the double suction turbine fan having respective air inlets; one lateral side of the double suction turbine fan having an air outlet; one side of the casing of the power supply having air outlets, receptacles, and a power switch; another side of the casing of the power supply having a plurality of holes arranged like a net; a lower side of the cover having a round hole corresponding to the air inlet.

Abstract: A two-suction turbine fan device comprises: a frame being a two-sheet structure; each sheet of the frame having a respective suction opening; one lateral side of the frame having a vent opening; a fan being installed at an interior of the frame; a motor being installed in the rear side of a rotary shaft of the fan; the fan having a plurality of blades; each blade having a long and flat shape. When the two-suction turbine fan device is installed in the computer device, the two-suction turbine fan device will suck hot air from a power supply and a computer mainframe. An outer side of each sheet of the frame is installed with a plurality of ribs which are arranged as a radiated shape for guiding conductive wires. The frame has a plurality of tenons at a periphery thereof.
