As a preferred embodiment of this embodiment, the air guiding groove 43 extends from the side of the second air guiding cavity 42 along the horizontal direction, so that the air guiding groove 43 is relatively easy to manufacture and mold.
Preferably, the wind scooper 4 includes a wind guiding barrel 44 enclosing the first wind guiding cavity 41, a wind guiding seat 45 enclosing the second wind guiding cavity 42, and a wind guiding frame 46 enclosing the wind guiding groove 43. The air duct 44 extends downward from the bottom of the air guide seat 45, and the air guide frame 46 extends laterally from the side of the air guide seat 45.

Preferably, the air duct 44 has a wall thickness of 0.5mm to 5 mm. The wall thickness of the air duct 44 specifically guides the distance between the inner wall of the air duct 44 close to the first air guiding cavity 41 and the outer wall of the air duct 44 far from the first air guiding cavity 41. If the wall thickness of the air duct 44 is designed to be too thin, the air duct 44 is easily deformed and damaged in the using process; if the wall thickness of the air guide duct 44 is too large, the air guide duct 44 will be large, heavy and costly.

The wall thickness of the air guiding seat 45 specifically guides the distance between the inner sidewall of the air guiding seat 45 close to the second air guiding cavity 42 and the outer sidewall of the air guiding seat 45 far away from the second air guiding cavity 42. If the wall thickness of the air guide seat 45 is designed to be too thin, the air guide seat 45 is easily deformed and damaged in the using process; if the wall thickness of the wind guide seat 45 is too large, the wind guide seat 45 will have a large size, a large weight, and a high material cost. Here, the wall thickness of the air guide seat 45 is set to 0.5mm-5mm, which is beneficial to ensuring the strength of the air guide seat 45, and can control the size, weight and material cost of the air guide seat 45 within a reasonable range, and the comprehensive performance is better.

If the distance between the air guide seat 45 and the first cooling fan 3 is designed to be too small, the interference between the air guide seat 45 and the first cooling fan 3 is easily caused; if the distance between the air guiding seat 45 and the first heat dissipating fan 3 is too large, the air guiding seat 45 will have a larger size, a larger weight, and a higher material cost. Here, the distance between the air guiding seat 45 and the first heat dissipating fan 3 is set to be 2mm-50mm, which is beneficial to preventing the interference between the air guiding seat 45 and the first heat dissipating fan 3, and can control the size, weight and material cost of the air guiding seat 45 within a reasonable range, and the comprehensiveness is better.
Preferably, the wall thickness of the air guide frame 46 is 0.5mm-5 mm. The wall thickness of the air-guiding frame 46 specifically guides the distance between the inner wall of the air-guiding frame 46 close to the first air-guiding cavity 41 and the outer wall of the air-guiding frame 46 far from the first air-guiding cavity 41. If the wall thickness of the air guide frame 46 is designed to be too thin, the air guide frame 46 is easily deformed and damaged in the using process; if the wall thickness of the air guide frame 46 is too large, the air guide frame 46 will be large in size, heavy in weight, and high in material cost. Here, the wall thickness of the air guide frame 46 is set to 0.5mm-5mm, which is beneficial to ensuring the strength of the air guide frame 46, and can control the size, weight and material cost of the air guide frame 46 within a reasonable range, and the comprehensive performance is better.
