A heat dissipation fan includes a fan module and a flow guide device. The fan module further includes a motor stator set and a fan rotor. The motor stator set provides an axial core and an annular join part. The fan rotor is rotationally joined to the axial core. The flow guide device provides a plurality of flow guide blades. An annular section is provided on the flow guide blades and the flow guide blades is integrally made with the annular join part or the flow guide blades is integrally made with a frame and the frame being attached to the motor stator set. The annular section can reduce an eddy flow area, which is formed due to an electronic component impeding the air flow and creating counter air flow under the flow guide blades, so as to increase flow speed and flow rate of the air flow blown by the fan rotor and approaching an electronic component.
