ABSTRACT:
A centrifugal fan type cooling module includes a centrifugal fan and a radiator. The centrifugal fan provides a fan rotor with fan blades and an axial shaft and a fan stator set with an axial core, an upper cover and a frame. The fan blades extend straight forward radially with the outer end of each fan blade has an enlarged curve end part and the rest part of the respective fan blade has a width shorter than the axial shaft. The frame encloses and fits with the top of the radiator and the axial shaft is rotationally joined to the axial core such that a hollow space is formed between the radiator and the fan rotor. Heat from an electronic component is transmited to the radiator and removed outward quickly in all directions by way of upward suction force of the centrifugal fan instead of contacting other electronic members directly.
