[0029] The interior of the fan bracket 101 is hollow, and the support rod 101a is fixed inside the fan bracket 101. One end of the outer wall of the first motor 102 is fixedly connected to the outer wall of the support rod 101a, and one end of the outer wall of the fan blade 103 is fixedly connected to the rotating shaft of the first motor 102; the fan blade 103 is rotated by the first motor 102, thereby accelerating the air flow speed around the heat collection assembly 200, so that the heat collection assembly 200 can dissipate heat more efficiently. The function of the support rod 101a is to support and fix the first motor 102.

[0030] A heat collecting column 201a is protruded at the center of the top of the outer wall of the heat collecting base 201, and there are several groups of heat dissipating fins 201b, each group of which has no less than one heat dissipating fin 201b; the function of the heat collecting base 201 and the heat collecting column 201a is to absorb the heat dissipated by the CPU and conduct the absorbed heat to several groups of heat dissipating fins 201b, and dissipate the heat through several groups of heat dissipating fins 201b.

[0031] The second motor 301 is arranged on the outer wall of the support rod 101a at one end away from the first motor 102, the outer wall axis of the rotating lever 302 is fixedly connected to the rotating axis of the second motor 301, and a plurality of cleaning rods 303 are arranged at the bottom of one end of the outer wall of the rotating lever 302, and the plurality of cleaning rods 303 are respectively slidably connected at the interlayers of different heat dissipating fins 201b; the second motor 301 is supported and fixed by the support rod 101a, and the function of the second motor 301 is to drive the rotating lever 302 to rotate, and the rotating lever 302 drives the plurality of cleaning rods 303 to rotate with the central axis of the heat collecting column 201a as the center, and through the rotation of the plurality of cleaning rods 303, the dust in the gaps between the plurality of heat dissipating fins 201b is cleaned.

[0032] Air exchange slots 201c are provided between the groups of heat dissipation fins 201b; the function of the air exchange slots 201c is to allow the air outside the heat collection assembly 200 to enter the inside of the heat collection assembly 200 more conveniently.

[0033] A plurality of connecting rods 201d are arranged at the outer periphery of the top of the outer wall of the heat collecting base 201, and connecting plates 201e are arranged at the top and bottom of the connecting rods 201d and the top and bottom of the fan bracket 101; the connecting plates 201e of the outer wall of the fan bracket 101 and the connecting plates 201e at the top and bottom of the connecting rods 201d are connected by bolts, so as to fix the heat collecting assembly 200 and the fan bracket 101.

[0034] The heat collecting assembly 200 is made entirely of copper or aluminum; this configuration makes the heat dissipation and heat collection of the heat collecting assembly 200 more effective.

[0035] The fan bracket 101 and the connecting rod 201d are fixedly connected by bolts.

[0036] Working principle: Bolts are sequentially passed through the connecting plates 201e at the top and bottom of the outer wall of the fan bracket 101 and the connecting plates 201e at the top and bottom of the connecting rod 201d and the computer motherboard, so as to fix and connect the heat dissipation component 100, the heat collection component 200 and the computer motherboard. When fixed, the computer CPU needs to be located directly below the bottom of the outer wall of the heat collection column 201a. Under normal conditions, the heat is absorbed by the computer CPU through the heat collection column 201a, and the heat is conducted to several groups of heat dissipation fins 201b through the heat collection base 201, and the heat is dissipated through the heat dissipation fins 201b. At the same time, the first motor 102 causes the fan blades 103 to rotate. By rotating the fan blades 103, the air flow speed around the heat dissipation fins 201b is accelerated, thereby improving the heat dissipation efficiency of several groups of heat dissipation fins 201b. When a large amount of dust accumulates between several groups of heat dissipation fins 201b, the power supply of the second motor 301 is started, and the second motor 301 rotates the rotating lever 302. The rotating lever 302 drives several groups of cleaning rods 303 to slide in the gaps between several groups of heat dissipation fins 201b. The cleaning rods 303 are used to clean the dust accumulated in the heat dissipation fins 201b, thereby avoiding clogging of the radiator due to a large amount of dust accumulation, thereby affecting the overall heat dissipation efficiency of the heat dissipation device.

[0037] Among them, the second motor 301 and the first motor 102 as well as their power sources are all very mature existing technologies in real life, and therefore will not be described in detail here.
