[0020] The utility model provides a technical solution: Figure 1 - Figure 4 As shown, in this embodiment, a heat dissipation device for a computer includes a heat dissipation device body 1, one side of the heat dissipation device body 1 is fixedly connected to a gas steering box 2, a toggle plate 4 is provided inside the gas steering box 2, one side of the outer wall of the toggle plate 4 is fixedly connected to a protrusion 17, a sliding groove 9 is provided on one side of the inner wall of the gas steering box 2, and an L-shaped sliding frame 6 is slidably connected to the inner wall of the sliding groove 9, a toggle rod 5 is fixedly connected to the middle part of the upper end of the L-shaped sliding frame 6, one side of the outer wall of the toggle rod 5 is slidably connected to one side of the outer wall of the protrusion 17, and a return spring 8 is fixedly connected to both ends of the L-shaped sliding frame 6, and a plurality of rotating blades 3 are rotatably connected to the inner wall of the gas steering box 2 near the edge, and a connecting block 7 is fixedly connected to one side of the plurality of rotating blades 3 near the edge, and one side of the plurality of connecting blocks 7 is connected to the L The upper end of the L-shaped sliding frame 6 is rotatably connected. By opening the heat sink body 1, the driving gear 13 drives the driven gear 14 to rotate, and the protrusion 17 pushes the toggle lever 5 to make the L-shaped sliding frame 6 slide in the sliding groove 9. When the protrusion 17 slides away from the toggle lever 5, the reaction force of the return spring 8 pushes the L-shaped sliding frame 6 in the opposite direction, thereby realizing the reciprocating sliding of the L-shaped sliding frame 6 in the sliding groove 9. While sliding, the L-shaped sliding frame 6 pulls the connecting block 7 to rotate the rotating blade 3, changing the direction of the wind blown out of the heat sink body 1, avoiding the heat dissipation dead corner when the heat sink body 1 dissipates heat to the electrical components in the computer, thereby improving the heat dissipation efficiency of the computer. A bidirectional drive device is installed inside the heat sink body 1, and the output ends of the bidirectional drive device are respectively connected to the drive gear 13 and the fan.

[0021] like Figure 3 and Figure 4 As shown, the output end of the heat dissipation device body 1 is connected to the driving gear 13, and one side of the driving gear 13 is engaged with the driven gear 14. One side of the driven gear 14 is fixedly connected to one side of the dial 4. Through the cooperation of the driving gear 13 and the driven gear 14, the rotational force of the heat dissipation device body 1 can be slowed down to prevent the rotating blades 3 from rotating too fast.

[0022] like Figure 3 and Figure 4 As shown, a mounting bracket 15 is fixedly connected to one side of the inner wall of the gas steering box 2, and the middle part of one side of the mounting bracket 15 is rotatably connected to one side of the driven gear 14.

One end of the four disassembly bolts 11 is threadedly connected to one side of the heat sink body 1. The protective cover 12 can protect the heat sink body 1 to prevent external force from hitting the heat sink body 1 and damaging the heat sink body 1.

[0025] like Figure 1 and Figure 2 As shown, the outer wall of the heat sink body 1 is threadedly connected with a plurality of mounting bolts 10 , and the heat sink can be installed in a computer through the mounting bolts 10 to cool the electronic components in the computer.

[0026] The utility model provides a heat dissipation device for a computer, and the specific working principle is as follows:

[0027] When the computer is in use, the heat sink body 1 is turned on, the driving gear 13 drives the driven gear 14 to rotate, and the protrusion 17 pushes the toggle lever 5, causing the L-shaped sliding frame 6 to slide in the sliding groove 9. When the protrusion 17 slides off the toggle lever 5, the reaction force of the return spring 8 pushes the L-shaped sliding frame 6 in the opposite direction, thereby realizing the reciprocating sliding of the L-shaped sliding frame 6 in the sliding groove 9. While the L-shaped sliding frame 6 slides, the connecting block 7 pulls the rotating blades 3 to rotate, thereby changing the direction of the air blown out of the heat sink body 1 and cooling the electronic components in the computer.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
