Specifically, the wind scooper 100 includes an air inlet portion 110 and an air outlet portion 120. The air inlet portion 110 allows the heat dissipation gas to enter, and correspondingly, the air inlet portion 110 is surrounded to form an air inlet. The air outlet portion 120 allows the heat dissipation gas to be discharged, correspondingly, the air outlet portion 120 is surrounded to form an air outlet, and the air outlet is communicated with the air inlet through an air guide channel. The air guide cover 100 can guide air from the air inlet into the air guide channel and exhaust the air from the air outlet, so as to effectively guide the flow direction of the heat dissipation air. Meanwhile, the air outlet part 120 is an annular shell, and the air outlet formed by surrounding the air outlet part 120 is also in a closed annular shape, so that the sealing performance of the air guide channel is effectively enhanced, the heat dissipation gas is discharged out of the case according to the set flow direction, and the gap leakage of the heat dissipation gas and the heat crosstalk formed thereby are avoided.

In an embodiment of the present invention, the air outlet portion 120 of the wind scooper 100 is designed as an annular housing, which can effectively enhance the wind guiding capability of the wind scooper 100. Optionally, the air outlet portion 120 of the wind scooper 100 is circular, square or irregular. As shown in fig. 1 to 4, the following embodiments are described only by taking the square annular air outlet part 120 as an example, and in other embodiments, the air outlet part 120 may have other shapes adapted to the heat dissipation module 500. Meanwhile, the wind scooper 100 guides the high-temperature heat dissipation gas exhausted by the heat dissipation module 500 to the outside of the chassis and exhausts the heat dissipation gas during the operation. The heat dissipation module 500 has various structural forms, and the air inlet 110 of the wind scooper 100 is also adapted to the structure of the heat dissipation module 500.

The air guiding cover 100 covers at least a part of the heat dissipation module 500 during use, and other electronic components are also mounted on the board card body 400 toward one surface of the air guiding cover 100, and the air guiding cover 100 needs to avoid the electronic components during mounting. The air outlet portion 120 in this embodiment can avoid the electronic component on the board card body 400 at the first air outlet section 121, and simultaneously, ensures good sealing performance of the air guide channel. It can be understood that the shape of the first air outlet section 121 is adapted to the shape of the electronic device to be avoided, and the height of the first air outlet section 121 is attached to the heat dissipation fan 520.

In an embodiment of the present invention, the diameter of the diameter-expanding section 123 is expanded only to a side close to the U-shaped opening of the air inlet portion 110, and further, the second air outlet section 122 is protruded to a side of the board card body 400 relative to the first air outlet section 121, so as to maintain the flatness of one side surface of the wind scooper 100 away from the board card body 400, and facilitate installation of other structures. In one embodiment, the diameter expanding section 123 and the second air outlet section 122 form a plurality of step-shaped inclined surfaces, the cross section of each inclined surface can be a straight line or a curve, that is, the diameter expanding section 123 can be an arc transition surface; the diameter expanding section 123 can effectively increase the air guiding space of the air duct, and ensure the stable flow of the air flow.
