Description

Wind shield

The invention relates to an air guiding structure, in particular to an air guiding hood for dissipating heat from an electronic device.

With the continuous advancement of technology, various electronic products are increasingly used in daily life. Since electronic devices are usually equipped with highly integrated electronic components, these electronic components emit a large amount of heat during use, so the heat dissipation problem of electronic devices is an important point in electronic design.

Common electronic devices, such as computers, often use air-cooling methods to dissipate heat-generating electronic components. In view of the aesthetic problem, the fan-equipped electronic device housing usually has the air inlet and the air outlet of the fan on the same surface. However, in the trend of miniaturization of the electronic device, the air inlet is usually closer to the air outlet, and the air inlet is in a negative pressure state during the heat dissipation process, so that the hot air discharged from the air outlet is again sucked into the air outlet, resulting in The returning hot air is heated by circulation to affect the heat dissipation effect.

In view of the above, it is necessary to provide an air hood that can effectively avoid the circulating heating phenomenon caused by the return of hot air.

An air deflector capable of effectively avoiding the circulating heating phenomenon caused by the return of hot air will be described below by way of a specific embodiment.

An air hood includes a top plate, a bottom plate opposite to the top plate, a plurality of side plates, a wind shield, an air inlet, and an air outlet. The plurality of side plates are connected end to end and located between the top plate and the bottom plate, and the plurality of side plates are respectively connected to the top plate and the bottom plate to define a receiving cavity. The wind deflector protrudes from an outer surface of one of the plurality of side plates, and the two ends of the wind deflector extend along the outer surface of the first side plate toward the top plate and the bottom plate, respectively. The air inlet and the air outlet are both disposed on the first side plate, and the air inlet is located at one side of the wind shield, and the air outlet is located at the other side of the wind shield away from the air inlet.

The air hood provided by the invention adopts a windshield to separate the air inlet and the air outlet which are opened on the side panel, and can effectively prevent the hot air discharged from the air outlet from being sucked into the air inlet again, and the circulating air is heated and recirculated. In the case where the distance between the air inlet and the air outlet is relatively close in consideration of the aesthetic problem, the heat dissipation effect is still not affected.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

1 and 2, an embodiment of the present invention provides an air hood 10 including a top plate 11, a bottom plate 12, four side plates 13, a wind shield 14, an air inlet 15, and an air outlet 16.

The top plate 11 has a substantially flat shape, and the bottom plate 12 is disposed opposite to the top plate 11. In this embodiment, the top plate 11 and the bottom plate 12 are disposed in parallel with each other.

The four side plates 13 are connected end to end to form an annular shape, and four side plates 13 are disposed between the top plate 11 and the bottom plate 12. The upper and lower edges of the four side plates 13 are respectively respectively connected to the edges of the top plate 11 and the bottom plate 12, so that the top plate 11, the bottom plate 12 and the four side plates 13 together form a receiving cavity 100. The receiving cavity 100 can be used for accommodating the electronic device 20 to protect the electronic device 20 . It should be noted that the number of the side plates 13 is not limited to four, and the number of the side plates may also be three, five, six or more. In the present embodiment, only four side plates 13 will be described as an example.

The wind deflector 14 is protruded from one of the four side panels 13. For convenience of description, the side panel formed with the wind deflector 14 is defined as the first side panel 130. The two end portions of the wind deflector 14 extend along the outer surface of the first side plate 130 in a direction toward the top plate 11 and the bottom plate 12, respectively. The wind deflector 14 may extend linearly or in an arc shape toward the top plate 11 and the bottom plate 12 on the outer surface side of the first side plate 130. In this embodiment, the wind deflector 14 extends linearly in the direction of the top plate 11 and the bottom plate 12. Further, in this embodiment, the wind deflector 14 is perpendicular to the top plate 11 along the extending direction of the outer surface of the first side plate 130. Since the top plate 11 and the bottom plate 12 are disposed in parallel with each other, the wind deflector 14 is also perpendicular to the bottom plate 12 along the extending direction of the outer surface of the first side plate 130.

The air inlet 15 and the air outlet 16 are both formed on the first side plate 130. The air inlet 15 is located on one side of the windshield 14 , and the air outlet 16 is located on the other side of the wind shield 14 away from the air inlet 15 .

The air hood 10 is separated from the air inlet 15 and the air outlet 16 of the first side plate 130 by the windshield 14 , so that the hot air discharged from the air outlet 16 can be effectively prevented from being sucked into the air inlet 15 again, thereby preventing hot air from flowing back. The phenomenon of being heated by the circulation occurs, so that the heat dissipation effect is not affected when the air inlet 15 and the air outlet 16 are disposed at a relatively close distance.

Preferably, the air hood may further include a first air guiding plate 17 and a second air guiding plate 18 protruding from an outer surface of the first side plate 130. The first air deflector 17 is in contact with one end of the wind deflector 14 , and the second air deflector 18 is in contact with the other end of the wind deflector 14 . In this embodiment, the first air deflector 17 is in contact with the end of the wind deflector 14 adjacent to the top plate 11 and extends to both sides of the wind deflector 14; the second air deflector 18 and the wind deflector 14 ends adjacent to one end of the bottom plate 12 and extend toward both sides of the wind deflector 14.

It should be noted that the first air deflector 17 can extend along a straight line, an arc or a wavy line on the outer surface of the first side plate 130, as long as the air inlet 15 and the air outlet 16 are located adjacent to the first air deflector 17. One side of the bottom plate 12 is sufficient, so that the hot air from the air outlet 16 blocked by the wind deflector 14 will be guided by the first air deflector 17 away from the air inlet 15. Of course, the second air deflector 18 can also extend along the straight line, the arc or the wavy line on the outer surface of the first side plate 130, and ensure that the air inlet 15 and the air outlet 16 are located adjacent to the top plate 11 of the first air deflector 17 . One side. In this embodiment, the first air deflector 17 and the second air deflector 18 all extend in a straight line, and the first wind deflector 17 extends on the outer surface of the first side panel 130 in a direction parallel to the top panel 11 . The second air deflector 18 extends in a direction parallel to the bottom plate 12 on the outer surface of the first side plate 130.

Further, the two ends of the wind deflector 14 can be designed to be respectively connected to the top plate 11 and the bottom plate 12. The first air guiding plate 17 is located at the junction of the first side plate 130 and the top plate 11, and the second air guiding plate 18 is located at the junction of the first side panel 130 and the bottom panel 12.

It should be noted that the extending direction of the first air deflector 17 and the second air deflector 18 may be perpendicular or oblique to the extending direction of the wind deflector 14 . In this embodiment, the first guide is aesthetically pleasing. The extending direction of the wind plate 17 and the second air guiding plate 18 is perpendicular to the extending direction of the wind deflector 14.

Preferably, the air hood 10 further includes a partition 19 which is located at a side plate portion between the air inlet 15 and the air outlet 16 and extends from the inner surface of the first side plate 130 into the receiving cavity 100. The end of the partition 19 away from the first side plate 130 is not in contact with the other side plates 13, thereby separating the receiving cavity 100 into two communicating portions, thereby forming a U-shaped air flow path to facilitate air flow. In this embodiment, the partition 19 extends in a direction perpendicular to the first side plate 130.

In addition, those skilled in the art can make other changes in the spirit of the present invention. Of course, the changes made in accordance with the spirit of the present invention should be included in the scope of the present invention.
