Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an air hood for dissipating heat of an electronic component. [0002] 先前 [Prior Art] When an electronic component such as a CPU is operated, a large amount of heat is generated. In order to better dissipate heat, an air hood is generally provided on the electronic component to match the fan. After the cold air blown by the fan enters the air hood, the flow rate is increased by τ, /λ. J, thereby speeding up the heat dissipation rate. 〇 [0003] 导 An air hood that is fixed to a computer case. The air hood includes a top cover and two side covers. The two side covers extend perpendicularly from opposite ends of the top cover toward one side of the cover to form an air inlet and an air outlet opposite the air inlet. When in use, the electronic components are dissipated into the air hood and placed close to the air inlet. Set the fan to the air inlet of the air hood. The fan blows the cooling airflow into the air inlet. The airflow absorbs the demon of the electronic components and flows through the electronic components near the air outlet. However, different types of air ducts are required for the electronic components of different sizes. For example, for single-core CPUs and dual-core CPUs, windshields with different lengths are required.

The limiting hole 132 is disposed adjacent to the receiving groove 135 and is connected to the receiving groove 135. 0 099107723 Form No. A0101 Page 4 / Total 17 Page 0992013893-0 201132921 [0012] [0014] [0015] Ο [0016] Three top boards! 5 is substantially rectangular, and a limiting protrusion 151 is formed on each of the opposite sides. The two limiting protrusions 151 are respectively disposed in the two limiting holes U2 of the second cutting plate 13 so that the third page board 15 slides in the receiving groove 135 of the second top plate 13 without coming out. Referring to FIGS. 5 and 6, each of the side covers 20 includes a substrate 21, a slider 23, and a rotating plate 251. The plate 23 is slidably coupled to the substrate 21. Rotate and slide the slide ^ to rotate. The substrate 21 is substantially rectangular, and the opposite sides thereof are respectively opened with a limiting hole 212, wherein two ends of the one side are respectively provided with a matching_213.

The receiving groove 135 of the top plate slides without being pulled out. Then, the mating portion 213 of the substrate 21 of the side cover 20 is inserted into the fixing portion 112 of the first top plate 11 of the top cover 1 so that the substrate 21 and the first top plate 11 are fixedly coupled. Then, the slide plate 23 is received in the receiving cavity 215 of the substrate 21, and the limiting shaft 231 of the sliding plate 23 passes through the limiting hole 212 of the substrate 21. Finally, the two rotating shafts 251 of the rotating plate 25 are respectively threaded through the shaft holes 235 of the two connecting portions 232 of the sliding plate 23, so that the rotating plate 25 can be rotated relative to the sliding plate 23. Referring to FIG. 7, when the air guiding cover is used, according to the electronic device The length of the electronic component causes the second top plate 13 to slide relative to the first top plate, the third top plate 15 slides relative to the second top plate 13, and the slide plate 23 slides relative to the substrate 21, thereby adjusting the length of the air guiding cover 100, so that the wind guide The cover 1 can be applied to electronic components of different sizes. Further, the rotating plate 25 is rotatable relative to the slider 23 to change the rotation angle of the rotating plate holder, thereby changing the direction of the wind flow of the air outlet 32.
