Thermal grease smearing apparatus

A thermal grease smearing apparatus for smearing thermal grease on a bottom surface of a heat sink, the thermal grease smearing apparatus comprising:

• a platform configured to receive a heat sink;
• a supporting post projecting upwardly from the platform;
• a bracket comprising a bottom plate defining with at least one smearing hole, and a top plate defining a through hole;
• a shifting mechanism extending laterally from the bracket, the shifting mechanism adapted to mount the bracket to the supporting post and to adjust a height <I accept.> of the bracket relative to the platform;
• a thermal grease pipe received in the through hole and mounted to the top plate of the bracket, the thermal grease pipe comprising a pipe body comprising an upper opening for introducing thermal grease, a lower opening for applying the thermal grease onto the bottom surface of the heat sink, and a smearing portion adjacent to the lower opening;
• when the bracket is positioned in a working position, a selected one of the at least one smearing hole is aligned with the bottom surface of the heat sink, a lower surface of the bottom plate abuts the bottom surface of the heat sink, and the smearing portion is adapted to rotate about a central axis of the thermal grease pipe and to smear the thermal grease uniformly on the bottom surface of the heat sink.
