A fluid moving device with a heat radiation, which is mounted to a conductive part to dissipate heat from a heat generation part under the fluid moving device and another heat generation part around the first heat generation part, includes a first frame member, which has an area thereof being equal to that of the conductive part and a base member being movably attached with the fan wheel, and a second frame member, which has a second hollow part with an area thereof being greater than the first frame member and provides a projection section extending beyond four sides of the first frame member. Once the fan wheel rotates, the fluid is dragged to enter the fluid moving device via the second hollow part and to leave via the first hollow part so as to dissipate heat in and around the conductive part.
