Detailed ways

Please refer to shown in Fig. 1, the air deflector of the radiator of computer motherboard of the present utility model is that a cover body 10 has an upper plate 11, the right side plate 12 and the left side plate 13 to form. The upper plate includes an expansion plate 112 extending from one side of a flat plate 111 . The other side of the expansion board 112 extends from the first top board 113 and the second top board 114 . The end 115 of the second top board 114 is inclined downwards to form a height difference with the end of the first top board 113 . An upper side plate 116 connects adjacent sides of the first top plate 113 and the second top plate 114 with height difference. The other ends of the first top plate 113 and the second top plate 114 respectively extend downward from the right side plate 12 and the left side plate 13 . There are two fasteners 117 on the top of the first top board 113 for combining with other fixing components to fix the cover body 10 . A first ventilation hole 14 is formed under the first top plate 113 , between the inner side of the right side plate 12 and the upper side plate 116 . A second ventilation hole 15 is formed under the second top plate 114 , the inner side of the left side plate 13 and the bottom of the upper side plate 116 .

Please refer to FIG. 2 , the CPU of a general computer mainframe 20 is combined with a radiator 21 to dissipate the heat generated by the CPU. The side of the CPU is provided with electronic parts 22 supporting the CPU to provide the power required by the CPU. Tests have shown that the electronic component 22 supporting the CPU emits about a quarter of the heat generated by the CPU itself during operation. Generally, the existing wind deflector and the wind deflector of the above-mentioned patent are only covered on the periphery of the CPU heat sink 21, and cannot directly dissipate heat to the electronic parts 22 supporting the CPU, so it is still impossible to effectively dissipate heat inside the main computer 20. .

The feature of the present utility model is that the first ventilation hole 14 of the cover body 10 is covered on the periphery of the CPU radiator 21; and the second ventilation hole 15 is covered on the periphery of the electronic parts 22 supporting the CPU.
