It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Example 1

A transition part 30 is arranged between the first diversion part 10 and the second diversion part 20, which plays a role in well connecting the first diversion part 10 and the second diversion part 20, so that the air flow is better diverted; the ribs 40 are vertically disposed in the transition portion 30, i.e. at the joint of the first flow guiding portion 10 and the second flow guiding portion 20, so as to ensure that the ribs 40 have sufficient distances from the openings of the first flow guiding portion 10 and the second flow guiding portion 20, respectively, and are located at the positions to cut and squeeze the air flow well.

The first flow guiding part 10, the transition part 30 and the second flow guiding part 20 are of an integrated structure, and the wall thicknesses of the first flow guiding part 10, the transition part 30 and the second flow guiding part 20 are consistent, so that the better forming flow guiding noise reduction device is convenient; the whole body can adopt a plastic material integrated injection molding process, so that the whole tightness is better.

In this embodiment, the cross section of the first flow guiding portion 10 in the vertical direction is rectangular, and the cross section of the second flow guiding portion 20 in the vertical direction is square, so as to ensure that the width of the first flow guiding portion 10 is greater than that of the second flow guiding portion 20, and the height of the first flow guiding portion is less than that of the second flow guiding portion 20, so that the air flow can be compressed and released in different directions.

The working principle of the flow guiding noise reduction device in this embodiment is as follows:

specifically, the air flow enters from one end of the first guiding part 10, passes through the spindle-shaped rib 40 and is cut into two air flows, the two air flows are compressed in the width direction of the first guiding part 10 (i.e. the horizontal direction of the first guiding part 10) and are released in the height direction of the first guiding part 10 (i.e. the vertical direction of the first guiding part 10) under the extrusion of the rib 40 (because the sharp angle of the rib 40 faces the first guiding part 10) and the side wall of the guiding noise reduction device, the compressed air flow and the released air flow are converged in the second guiding part 20 to form a stream of air flow, and finally the air flow is discharged out of the second guiding part 20.

In summary, the diversion noise reduction device of the utility model is provided with the first diversion part and the second diversion part, because the width of the first diversion part in the horizontal direction is larger than that of the second diversion part, and the height of the first diversion part in the vertical direction is smaller than that of the second diversion part, and the diversion noise reduction device is matched with the spindle-shaped ribs, so that the air flow entering the diversion noise reduction device is cut, extruded, released and converged, and finally the purpose of noise reduction is achieved.

In summary, the air-cooled radiator is connected with the diversion noise reduction device, so that the working noise of the digestion cooling radiator can be effectively absorbed after the airflow passes through the diversion noise reduction device, and the noise can be effectively reduced; meanwhile, after the performance requirement of the fan is properly reduced, the whole heat dissipation noise can be still restrained at a lower level, so that the production cost can be effectively reduced; furthermore, the rotating speed of the cooling fan can be properly adjusted to improve the cooling performance of the radiator, so that better customer experience is achieved, and the product competitiveness is improved.
