DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] The preferred embodiment of the heat dissipation device for a computer CPU provided by the utility model is as follows Figures 1 to 3 As shown: a heat dissipation device for a computer CPU comprises a fin heat sink 1, a support mechanism 2 is installed on the top of the fin heat sink 1, and a heat dissipation mechanism 3 is installed inside the support mechanism 2.

[0027] The support mechanism 2 includes a fixing frame 201 , the inner wall of which is fixedly connected to a supporting frame 202 , the inner wall of which is provided with heat dissipation holes 203 , and the outer wall of which is fixedly connected to a heat sink 204 .

[0028] The heat dissipation mechanism 3 includes a driving motor 301, which is installed on the top of the support frame 202. The output shaft of the driving motor 301 is fixedly connected to the driving shaft 302 through a coupling. The outer wall of the driving shaft 302 is fixedly connected to the active bevel wheel 303 and the first fan blade 304 from bottom to top. The outer wall of the active bevel wheel 303 is movably connected to the driven bevel wheel 305. The outer wall of the driven bevel wheel 305 is fixedly connected to the driven shaft 306. The driven shaft 306 is movably connected to the inner wall of the fixed frame 201. The outer wall of the driven shaft 306 is fixedly connected to the second fan blade 307, which facilitates the four second fan blades 307 to rotate in different directions. Then, when used in combination with the first fan blade 304, the function of multi-angle heat dissipation is realized, thereby improving the heat dissipation efficiency and solving the problem of slow heat dissipation.

[0029] Furthermore, four driven bevel wheels 305 are distributed at equal angles along the axial center line of the driving shaft 302 , and the sizes of the four driven bevel wheels 305 are smaller than the size of the driving bevel wheel 303 , so that every two symmetrical driven bevel wheels 305 rotate in opposite directions.

[0030] Furthermore, the second fan blades 307 are vertically distributed to the first fan blades 304, and the four second fan blades 307 are symmetrically distributed in pairs, so that heat dissipation can be performed at multiple angles.

[0031] Furthermore, there are four groups of heat dissipation holes 203 distributed on four sides of the fixing frame 201 , and each group of heat dissipation holes 203 is distributed in an array with a plurality of heat dissipation holes 203 , which facilitates ventilation and heat dissipation work inside the fixing frame 201 .

[0032] Furthermore, there are four groups of heat sinks 204 distributed on four sides of the fixing frame 201, and each group of heat sinks 204 has a number of heat sinks 204 distributed at equal intervals, and the heat sinks 204 and the heat dissipation holes 203 are staggered, which facilitates the heat sink 204 to quickly dissipate the exhausted hot air.

[0033] Furthermore, the heat sink 204 is made of aluminum, and the fin heat sink 1 is made of copper. The copper material can quickly absorb heat from the CPU, and the aluminum material can quickly dissipate heat. The combination of the two can improve the heat dissipation efficiency.

[0034] Furthermore, the fixing frame 201 is an “X”-shaped structure, and the middle dimension of the fixing frame 201 is larger than the dimension of the driving motor 301 , which facilitates the fixing frame 201 to install and fix the driving motor 301 .

[0035] When in use, first, the fin heat sink 1 quickly absorbs heat from the CPU through the copper material, and then the driving motor 301 is started to drive the driving shaft 302 to rotate, so that the driving shaft 302 drives the active bevel wheel 303 and the first fan blade 304 to rotate, and the active bevel wheel 303 drives the four driven bevel wheels 305 distributed at equal angles to rotate, and at the same time, the symmetrically distributed driven bevel wheels 305 rotate in the opposite direction, and then the hot air inside the fixing frame 201 is driven to be discharged to the top and the surroundings, thereby improving the heat dissipation efficiency, and when the hot air is discharged to the heat sink 204 through the heat dissipation holes 203, the aluminum material of the heat sink 204 can accelerate the dissipation speed of heat energy, further improving the heat dissipation efficiency.
