Description of the Invention: [Technical Field] The present invention relates to a heat sink, and more particularly to a heat sink having a dust removing mechanism. [Prior Art] In recent years, with the rapid advancement of computer technology, the operating speed of computers has been continuously improved, and the heating power of electronic components inside the computer mainframe has been continuously rising, in order to prevent overheating of electronic components inside the computer mainframe. Temporary or permanent failure of electronic components must provide sufficient thermal efficiency to the electronic components inside the computer. In general, the heat sink is mainly composed of a fan, a cooling fins and a heat pipe. The heat sink fin group is disposed at the air outlet ‘ of the fan and connected to the heat pipe for absorbing waste heat conducted by the heat pipe. The heat sink fin group is composed of a plurality of metal sheets arranged in parallel, and the adjacent metal sheets have a predetermined gap therebetween, and the waste heat is dissipated into the air via convection. Therefore, when the fan is in operation, the cooling airflow can flow to the heat dissipation fin group through the air outlet and pass through the gap between the metal sheets to convect the waste heat out of the body, thereby reducing the operating temperature of the internal electronic components. It is worth noting that when the radiator is used for a long time, the dust in the air will gradually _ in the _# _ metal. If it is not cleaned, too much dust will accumulate on the metal sheet, which will easily cause the wind blown by the fan to remove the waste heat from the heat sink fin group, resulting in a significant reduction in the heat dissipation capability of the heat sink. 200823637 1PD060579TW 22296twf.doc/006 SUMMARY OF THE INVENTION The present invention provides a heat sink having a dust removing mechanism that is inserted between heat radiating metal sheets by a dust removing mechanism to remove dust accumulated in the metal.
