Description

Wind shield

The invention relates to an air hood.

On the motherboard of an electronic device (such as a server), an air hood is usually installed, and the motherboard is usually provided with electronic components such as an expansion card near the air hood. The expansion card has a large heat dissipation, which makes the ambient temperature high. For this reason, a special fan is sometimes required to dissipate heat, which is a waste of resources.

In view of the above, it is necessary to provide an air hood that can simultaneously dissipate heat from surrounding electronic components.

An air hood includes a side plate provided with an opening and two sliding plates slidably disposed on the side plates and respectively located at opposite ends of the opening. When the two sliding plates slide toward each other, the opening can be gradually blocked by the two sliding plates.

An air hood includes a side plate provided with an opening and a sliding plate slidably mounted on the side plate at one end of the opening, the opening being gradually blocked by the sliding plate when the sliding plate slides toward the opening.

The side panel of the air duct of the present invention is provided with an opening for dissipating heat from the electronic components near the side panel, and the slidable slider adjusts the size of the opening when using electronic components of different specifications.

Figure 2 is an enlarged perspective view of a portion II of Figure 1.

Figure 3 is an enlarged perspective view of the slider of Figure 1 in another direction.

4 is a perspective assembled view of FIG. 1.

5 and 6 are perspective assembled views of the two slide plates of Fig. 4 when they are slid to different positions.

Referring to Figures 1 and 2 together, a preferred embodiment of the air duct 10 of the present invention includes a top panel 13, two side panels 11 and two sliders 20 extending vertically from opposite sides of the top panel 13, respectively.

The lower portion of the one side plate 11 is laterally disposed with a groove 12 communicating with one end of the side plate 11 , and the groove 12 includes a bottom wall 121 and two opposite side walls 122 . Each side wall 122 is provided with an L-shaped slide rail 14 bent toward the opposite side wall 122. An elongated opening 15 is defined in the middle of the bottom wall 121. The bottom wall 121 is respectively provided with an elongated locking portion 16 at each end of the opening 15. Each of the fastening portions 16 includes a plurality of vertical cross sections. A V-shaped card slot 162.

Referring to FIG. 3, each of the slide plates 20 has an elongated shape. The slide plate 20 is provided with a through hole 21 near the first end thereof. The through hole 21 is away from the side of the first end of the slide plate 20 toward the slide plate 20. The first end extends a resilient block 22, and an inner side of the block 22 protrudes from a first end of the sliding plate 20 to form a V-shaped buckle 222. An end opposite the first end of the slider 20 is the second end of the slider 20. The outer side of the slider 20 is provided at an adjacent second end with an operating portion 23 for facilitating operation of the slider 20. In the present embodiment, the operation portion 23 is a boss that protrudes from the slider 20 .

Referring to FIG. 4, during assembly, the two slide plates 20 are sequentially slid into the two slide rails 14 of the groove 12, so that the second ends of the two slide plates 20 are adjacent to each other, and the buckles 222 of the two slide plates 20 are respectively stuck. The card slot 162 of the corresponding fastening portion 16 is inserted into the opening 15 of the recess 12 . The two slide plates 20 can slide laterally along the two slide rails 14.

In use, when the electronic components outside the side panel 11 of the air guiding cover 10 provided with the opening 15 need to dissipate a large amount of heat, the two sliding plates 20 are respectively slid to the sides of the opening 15 until the two sliding plates 20 are completely opposite to the opening 15. turn on. At this time, the heat radiated from the electronic components outside the side plate 11 of the air hood 10 provided with the opening 15 enters the opening 15 of the air hood 10, and then the wind flow in the air hood 10 flows to the air hood 10 together. The tuyere reduces the temperature in the vicinity of the electronic component.

Referring to FIG. 5, when the electronic components outside the side plate 11 of the air hood 10 provided with the opening 15 are small and require a small amount of heat dissipation, the two slide plates 20 are slid toward each other, and the opening 15 is gradually replaced by the second slide plates 20. End occlusion.

Referring to FIG. 6 , when the electronic component is not disposed outside the side plate 11 of the air hood 10 having the opening 15 and the heat dissipation is not required, the two sliding plates 20 are slid to the second end of the two sliding plates 20 to abut. The opening 15 is completely blocked by the two slides 20.

When the slide plate 20 is slid to a predetermined position, the buckle 222 of the slide plate 20 is caught in the corresponding slot 162 of the corresponding fastening portion 16 to fix the slide plate 20 to the air hood 10.

In other embodiments, only one of the slides 20 and one of the hooks 16 on one side of the opening 15 may be provided, and the opening 15 is gradually blocked by the slide 20 as the slide 20 slides toward the opening 15.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. please. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
