[0023] A plurality of contact blocks 106 are evenly distributed on the surface of the adjustment plate 105 , and one end of the protrusion 104 away from the rotating rod 103 abuts against the contact block 106 .

[0024] The above scheme is adopted: the temperature of the radiator core 203 is monitored by the temperature sensor 109, and then the telescopic length of the telescopic rod 101 is controlled by the controller 108, so that the connecting rod 102 drives the rotating rod 103 to rotate on the surface of the adjustment plate 105, so that the protrusion 104 on the surface of the rotating rod 103 is against the contact block 106 at different positions, so that the servo motor 107 increases or decreases the rotation speed of the fan blade 202, thereby achieving the function of adjusting the heat dissipation efficiency of the device, and can automatically adjust according to the working load conditions to achieve the effect of increasing the heat dissipation capacity under high load and reducing energy consumption under low load.

[0025] like Figures 1 to 4 As shown, the heat dissipation mechanism 2 includes a fan housing 201, the interior of the fan housing 201 is rotatably connected to a fan blade 202, the surface of the fan housing 201 is fixedly connected to a radiator core 203, the side of the radiator core 203 is fixedly connected to a water tank 204, the top of the water tank 204 is fixedly connected to a water inlet pipe 205, the bottom of the water tank 204 is fixedly connected to a water outlet pipe 206, the side of the water tank 204 is fixedly connected to a plurality of fixing plates 207, the water outlet pipe 206 is located below the fan housing 201, and the appearance of the water outlet pipe 206 is in a "C" shape, and the material of the radiator core 203 is graphene heat dissipation material.

[0026] The servo motor 107 is located between the fan housing 201 and the fan blades 202, and the servo motor 107 and the fan housing 201 are fixedly connected. The adjustment plate 105 is located on the side of the servo motor 107 away from the fan blades 202, and the adjustment plate 105 is located inside the fan housing 201. The radiator core 203 is located in front of the fan housing 201. The side of the temperature sensor 109 away from the controller 108 is fixedly connected to the radiator core 203, and the side of the controller 108 is fixedly connected to the fan housing 201.

After the temperature sensor 109 senses the temperature on the surface of the radiator core 203, the controller 108 controls the water pump to start working, so that the liquid inside the water tank 204 flows, and the servo motor 107 is started to drive the fan blades 202 to rotate, so as to cool down the radiator core 203. When the radiator core 203 After the temperature reaches the first gear, the controller 108 controls the telescopic rod 101 to move half the length in the direction close to the controller 108, so that the telescopic rod 101 drives the rotating rod 103 to rotate a quarter of a turn on the surface of the adjustment plate 105 through the connecting rod 102, so that the protrusion 104 on the surface of the rotating rod 103 abuts against the second contact block 106, so that the servo motor 107 increases the rotation speed of the fan blade 202 and speeds up the heat dissipation efficiency. Similarly, when the telescopic rod 101 is completely moved to the inside of the controller 108, the protrusion 104 abuts against the third contact block 106 through transmission. At this time, the rotation speed of the fan blade 202 reaches the maximum value, so that the heat dissipation efficiency of the device is also the highest.
