Patent attributes
A test device for a heat dissipating fan, which is suitable for testing if the fan wheel is secured to the housing firmly, includes a support post, a transverse slide unit, which is disposed at the top of the support post and provides a transverse slide seat, a vertical slide unit, which is disposed at the transverse slide seat and provides a vertical slide seat. Further, the test device provides a clamping unit, a suction unit and a sensing element, which are moved with the vertical slide seat. The clamping unit clamps the housing and the suction unit absorbs the fan wheel. The heat dissipating fan is admitted in case of the sensing unit sensing the fan wheel being incapable of moving upward under the suction force and is carried away by the transverse slide unit in case of the sensing unit sensing the fan wheel being capable of moving upward under the suction force.
