Description of the Invention: [Technical Field] The present invention relates to a heat dissipation module, and more particularly to a heat dissipation module having a dust removal function group. [Prior Art] In recent years, with the rapid advancement of computer technology, the speed of computer operation has been improved, and the heating power of electronic components inside the computer has been continuously rising, in order to prevent overheating of electronic components inside the computer. In order to cause temporary or permanent failure of electronic components, sufficient heat dissipation performance must be provided to the electronic components inside the computer. Generally speaking, the heat dissipation module is mainly composed of a fan, a cooling fins and a heat pipe. The fin assembly is disposed at the air outlet of the hood and is connected to the heat pipe to absorb waste heat conducted by the heat pipe. The heat sink fin group is composed of a plurality of metal sheets arranged in parallel, and a gap is provided between adjacent metal sheets to provide waste heat to escape 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 of the wind hood, and pass through the gap between the metal sheets to discharge the waste heat out of the body by convection, thereby reducing the internal electronic components. Operating temperature. It is worth noting that when the heat sink is used for a long time, the dust in the air will gradually accumulate in the heat sink fin set and the windshield. If it is not cleaned, if too much dust accumulates in the heat sink fin group or the windshield, it is easy to cause airflow to remove the waste heat from the heat sink fin group, resulting in the heat dissipation module.

The heat sink 15 can be directly attached to an electronic component (not shown), such as a central processing unit or a high power chip, and the heat sink can conduct waste heat in the electronic component to the heat sink fin via the heat pipe 140. Group 120. When the fan 11 is driven to be in operation, the cooling airflow f can flow through the air inlet region 1〇2 of the hood 1〇〇 to the heat dissipation fin group 120 located in the air outlet region 1〇4, and passes through the heat dissipation fin group. The gap between the 12 turns is to convect the heat out of the air outlet 22 of the casing 2, thereby reducing the operating temperature of the electronic components inside the residual. ^ The value of the main thinking is that the diversion zone 106 is located between the inlet zone 1〇2 and the outlet zone 104, and the diversion zone I% has a main channel 1, for example, to guide most of the cooling airflow. It is flowed from the inlet zone 102 to the outlet zone 1〇4.

Referring to FIG. 2A, the dust removing device 130a may be disposed outside the deflector 114, such as an electrostatic generating device or a voltage-adjustable static generating device, which can supply power to the deflector 114 to bring the deflector 114. There is static electricity, and depending on the amount of dust in the environment, the voltage of the power supply is adjusted to determine the amount of static electricity on the deflector 114. In addition, referring to FIG. 2B, the dust removing device 13% can also be directly placed in the secondary channel l〇6b to remove the dust D by adsorption. The dust removing device 130b is, for example, a dust removing filter, a dust removing bag, or an electrostatic dust removing brush. In this regard, the invention is not limited. As described above, when the cooling airflow F passes through the diversion zone 1〇6, the entrained dust D is gradually pulled down by gravity, so that part of the dust D is adsorbed on the dust filter through the sub-channel l〇6b. Dust bags or electrostatic dust removers, while dust filters, dust bags or electrostatic dust brushes can be removed manually in a manual manner to keep them clean. Alternatively, the entrained dust D is negatively charged and falls downward by the positive electric charge (electrostatic) on the deflector 114 when passing through the flow guiding area 106 to be adsorbed on the deflector 114. When the static electricity generating means turns off the power supply so that the static electricity on the deflector 114 disappears, the dust on the deflector 114 is no longer attached and can be carried away by the air flow F2 to be discharged outside the hood 1GG. Therefore, the present invention can reduce the accumulation of dust D on the heat dissipation group 120 or the hood (8) to improve the heat dissipation performance of the heat dissipation module 1〇. As described above, the heat dissipation module of the present invention is provided with a secondary passage in the flow guiding area of the hood to collect dust from the cooling airflow that does not reach the heat dissipation fin group.
