Previous notebook computers cooling fan configuration devices have the following disadvantages

(1) Vertical Reflux of Cooling Fan

(2) It is easy to generate larger noise-the backflow of the air source interferes with the heat dissipation fan blades, which is easy to cause larger noise.

(3) the service life of the radiating fan is shortened,

The purpose of this assumption is to provide a notebook computer heat dissipation fan configuration device which can reduce backflow generation, reduce noise and prolong the service life of the fan.

The invention relates to a notebook computer heat dissipation fan configuration device, which comprises a computer shell with a first air inlet part, a second air inlet part and an air outlet part, wherein a heat dissipation seat corresponding to the first air inlet part is arranged in the shell to form a heat dissipation chamber with two open ends with the shell; the two ends of the heat dissipation seat respectively correspond to the second air inlet part and the air outlet part to form an air inlet and an air outlet; the second air inlet part has an air inlet direction; and a heat source is tightly pressed against the heat dissipation seat. The heat dissipation chamber is provided with axial flow fans one by one corresponding to the air inlet parts, and the fans deflect-angle along the air inlet direction, so that the air source can enter the air from the first and second air inlet parts, and the heat source in the heat dissipation chamber can be dissipated from the air outlet part.
