Field of the Invention 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 computer's speed has been continuously improved, and the power of the electronic components of the electric station has been continuously rising. In order to prevent the electronic heat inside the computer mainframe from causing temporary or permanent failure of the electronic components, it is necessary to provide sufficient heat dissipation performance to the electronic components inside the computer. Therefore, for high-heat-power electronic components such as a central processing unit, (4) (9), a north-produced chip, a south-bridge chip, and a temporary memory group, a heat sink can be added to reduce the temperature of these electronic components. • δ ′ heat dissipation is mainly composed of a fan, a heat-dissipating block group c=lng fms, and a heat pipe. The heat dissipation tab group = the air outlet σ of the fan, and is connected with the heat pipe, and (4) absorbs the waste heat of the heat pipe. The heat dissipation fin group is composed of a plurality of metal sheets arranged in parallel =, and = adjacent metal sheets There is a certain gap between the two, so that the waste heat can be dissipated into the air by the way. Therefore, when the fan is in operation, the cooling airflow can flow to the scaly group through the air outlet and pass through the gap between the metal sheets to The waste heat is discharged outside the body by convection, thereby reducing the operating temperature of the internal electronic components. The value note is that the dust in the air 200911097 --543twf.doc/n will gradually accumulate after the radiator has been used for a long time. Between the metal sheets of the heat sink fin group. / If too much dust accumulates on the metal sheet, the waste heat transmitted to the metal sheet will be blocked by the dust and cannot be effectively dissipated. In addition, the dust will also block the airflow of the fan, making convection. The effect is worse. Therefore, the dust will cause the problem that the waste heat is not easily removed from the political fin group, and the heat dissipation capability of the heat sink is greatly reduced. The present invention provides a heat sink having a dust removing mechanism for removing dust attached to a heat sink by a dust removing mechanism. The present invention provides a heat sink having a dust removing mechanism including a heat transfer assembly and a dust removing mechanism. The assembly includes a plurality of isotropically arranged metal fins. The dust removing mechanism includes a scrickle sweep and a transmission element. The scraping slide is disposed on one side of the metal fins and is adapted to slide along one side. The path sequentially contacts the metal fins. The transmission element is coupled to the scraper for driving the scraper to slide along the sliding path to scrape dust attached to the metal fins. In one embodiment of the invention, the dust removing mechanism Furthermore, a resetting element may be included. The resetting element is connected to the scraping so that the scraping normal is located at the first position on the sliding path, wherein the reverting element may be a spiml sPring or a helical spring. In an embodiment of the invention, the transmission element may include a wire disposed on the sliding path and adapted to be driven by an external force The scraping is performed from the first position 'monthly to a second position on the sliding path, and the resetting element can be connected to the scraping by the wire 200911097 ~ · - - - · · · · 543twf.doc / n.
