  • Patent number: 9115721
    Abstract: The present invention provides a turbofan and a graphics card with the turbofan. The turbofan comprises: a turbofan assembly which admits air in an axial direction and dispenses air in a radial direction; an inlet fan assembly disposed at an inlet of the turbofan assembly and disposed coaxially with the turbofan assembly; and a driving means for driving the turbofan assembly and the inlet fan assembly to rotate. The turbofan provided by the invention gathers the ambient air to the inlet through the inlet fan assembly disposed at the inlet of the turbofan assembly, so as to change a negative pressure state at the inlet. Consequently, the cooling efficiency of the turbofan is improved effectively and the noise of the turbofan is reduced.
