[0003] After searching, the Chinese patent with the announcement number CN219266891U discloses a notebook exhaust-type radiator. The notebook exhaust-type radiator includes a computer; a fixed plate, the fixed plate is arranged above the computer; a top plate, the top plate is rotatably mounted on one side of the fixed plate; a mounting box, the mounting box is fixedly mounted on the bottom of the top plate; two mesh plates, the two mesh plates are respectively fixedly mounted on both sides of the mounting box; a rotating shaft, the rotating shaft is rotatably mounted on the mounting box; fan blades, the fan blades are fixedly mounted on the rotating shaft; a connecting plate, the connecting plate is arranged on the side of the mounting box away from the computer; a fastening mechanism, the fastening mechanism is arranged on the fixed plate, the top plate and the connecting plate; a power mechanism, the power mechanism is arranged on the top plate and the rotating shaft.

The groove 13 is opened to place the position of fan blade 2 12 and fan blade 1 9, and the dustproof net 14 is to reduce dust from entering the radiator.

[0034] refer to Figure 2 、 Figure 3 The external teeth of the driving gear 6 are meshed with the external teeth of the driven gear ring 8, and the external teeth of the driving gear 6 are meshed with the external teeth of the driven gear block 11. The external rotation of the cylinder 7 is connected to the middle of the top dustproof net 14, and the external rotation of the connecting shaft 10 is connected to the inner wall of the cylinder 7. The external rotation of the connecting shaft 10 is connected to the inner wall of the driven gear ring 8.

[0035] refer to Figure 4 , the left and right sides of the top of the heat dissipation end 3 are fixedly connected with a sleeve 15, and an adjustment component is provided inside the sleeve 15, which includes a main ventilation disc 16, a circular groove 17, a slave ventilation disc 18, and a through-port 19. The outside of the main ventilation disc 16 is fixedly connected to the top of the inner wall of the sleeve 15, and the main ventilation disc 16 fits the top position of the inner wall of the sleeve 15, and the opening of the alignment groove 13 of the sleeve 15 is fixed. The circular groove 17 is opened in the middle of the interior of the sleeve 15, and the outside of the slave ventilation disc 18 is slidably connected to the inner wall of the circular groove 17. The through-port 19 is opened on the side away from the through hole 2. The opening 19 allows the teeth of the slave ventilation disc 18 to contact external components, thereby being pushed by external components to slide on the inner wall of the circular groove 17 and overlapping with the opening area of ​​the top main ventilation disc 16 to adjust the air volume.

[0036] Two long slots 20 are provided in the middle of the heat dissipation end 3, and the inner wall of the long slot 20 is rotatably connected with a connecting rod 21, and the top end of the connecting rod 21 is fixedly connected to a pushing gear 22, and the external teeth of the pushing gear 22 are meshed with the external teeth of the ventilation disk 18. The upper and lower sides of the pushing gear 22 are slidably connected to the inner wall of the through-port 19, and the bottom end of the connecting rod 21 is fixedly connected with a rotating block 23. The top of the rotating block 23 is in contact with the bottom end of the heat dissipation end 3. By rotating the rotating block 23, the pushing gear 22 is driven to rotate closely against the inner wall of the through-port 19 through the connection with the connecting rod 21 and mesh with the external teeth of the ventilation disk 18.

[0037] Working principle: When in use, the motor 5 fixed in the placement slot 4 is started to drive the driving gear 6 to rotate longitudinally, thereby rotating the driving gear 6 and the driven gear ring 8 and the driven gear block 11 that are laterally meshed with the driving gear 6 on the upper and lower sides. Because the cylinder 7 and the driven gear ring 8 are connected and the diameter of the connecting shaft 10 is equal to the diameter of the inner wall of the middle part of the driven gear ring 8 and the cylinder 7, and because the rotation of the driving gear 6 drives the driven gear ring 8 to rotate forward, and the driving gear 6 drives the driven gear block 11 to rotate in the opposite direction, the fan blade 1 9 and the fan blade 2 12 fixed on the outside of the connecting shaft 10 and the cylinder 7 will rotate in opposite directions, thereby realizing coaxial reversal, so that the diversion generated by the fan allows a more uniform air pressure distribution in the radiator air duct to ensure that heat can be more effectively transferred from the heat dissipation surface to the air, and push the hot air to be quickly discharged from around the notebook.

[0038] When using a lower load or the ambient temperature is low, the rotating block 23 can be rotated through the connection of the connecting rod 21 to drive the push gear 22 to rotate and engage with the external teeth of the secondary ventilation disk 18, so that the secondary ventilation disk 18 rotates on the inner wall of the circular groove 17 and the main ventilation disk 16 with the same air outlet size slot at the top to overlap the opening area. After the main ventilation disk 16 and the secondary ventilation disk 18 overlap, the outlet slot becomes smaller, and the air volume can be adjusted, thereby reducing energy consumption and noise. This not only helps to extend the service life of the fan and radiator, but also, when used at high loads, by rotating the rotating block 23 in the opposite direction to drive the push gear 22 to rotate and engage with the secondary ventilation disk 18 to increase the air volume, it can more effectively discharge heat from the notebook and ensure that the notebook maintains a stable temperature during long-term high-load operation.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
