[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1 See also Figure 1-Figure 8 , a heat dissipation chassis with a temperature warning function shown in the figure includes a chassis body 1, a heat dissipation mechanism, an auxiliary mechanism and a driving mechanism.

[0021] The auxiliary mechanism also includes a fixed plate 12 and a device box 13 which are rotatably connected to the inner wall of the second lifting block 11. One end of the driving tube 9 is coaxially fixedly connected to the fixed plate 12. The device box 13 is coaxially fixedly connected to the fixed plate 12. A connecting tube 14 which is connected to one end of the driving tube 9 is provided on the fixed plate 12. A through hole 15 which can be connected to the connecting tube 14 is provided on the side of the device box 13. A control component for controlling the connection state between the through hole 15 and the connecting tube 14 according to the rotation speed of the driving tube 9 is provided in the device box 13.

[0022] The control component includes multiple groups of centrifugal blocks 16 installed in the device box 13. Multiple groups of guide grooves 17 are opened in the device box 13. The connecting pipe 14 and the through hole 15 are connected to the guide groove 17. The centrifugal block 16 is slidably connected to the inner wall of the guide groove 17. One end of the centrifugal block 16 is fixedly connected to a return spring 18 fixedly connected to the guide groove 17. A conveying member for liquid pumping is provided in the device box 13.

[0023] The conveying member includes a wind wheel 19 fixedly installed on the side of the device box 13, a fixed box 20 is fixedly connected inside the second lifting block 11, the outer wall of the wind wheel 19 is rotatably connected to the inner wall of the fixed box 20, a plurality of groups of first pipes 21 are evenly arranged on the outer wall of the driving pipe 9, a plurality of groups of second pipes 22 connected to the first pipes 21 are evenly arranged in the fan blades 4, and a connecting pipe 23 connected to the water tank 6 is connected to the fixed box 20.

[0024] The conveying member also includes a pulling block 24 slidably connected to the inner wall of the water tank 6, the bottom end of the connecting pipe 23 is fixedly connected to the side of the pulling block 24, the connecting pipe 23 passes through the upper side of the water tank 6 and slides in fit with the water tank 6, a third pipe 25 for connecting the connecting pipe 23 and the water tank 6 is opened in the pulling block 24, and a tension spring 26 fixedly connected to the inner wall of the water tank 6 is fixedly connected to the side of the pulling block 24.

[0025] In this embodiment, when the printed circuit is running, the heat in the equipment components is conducted to the heat dissipating fins 3 through the radiator 2 inside the chassis body 1, and the temperature of the radiator 2 is monitored and warned by the temperature warning controller 37. When the temperature is greater than the set temperature, the driving mechanism drives the driving tube 9 to rotate, and the driving tube 9 drives the fan blades 4 to rotate. The fan blades 4 are arc-shaped, and during the rotation process, they help accelerate the airflow through the heat dissipating fins 3, thereby improving the heat transfer efficiency and accelerating the heat dissipation. At the same time, during the rotation of the fan blades 4, the cleaning cotton 5 on both sides will be driven to wipe and clean the heat dissipating fins 3 on both sides.

[0026] It is worth noting that the driving mechanism synchronously drives the reciprocating screw 8 to rotate, so that the second lifting block 11 drives the driving tube 9 to reciprocate and lift together with the first lifting block 10, thereby achieving the purpose of comprehensive cleaning and auxiliary heat dissipation of the entire heat dissipation fin plate 3. During the lifting process, the tension spring 26 will continue to pull the pulling block 24, so that the connecting tube 23 is continuously in a straight state.

[0027] When the operating power is low, the operating speed of the driving mechanism is low, and the driving tube 9 rotates slowly. At this time, the fixed disk 12 and the device box 13 rotate slowly, and the centrifugal force on the centrifugal block 16 is small. The centrifugal block 16 will continue to block one end of the through hole 15, so that the through hole 15 is not connected to the connecting tube 14. At this time, the device box 13 drives the wind wheel 19 to rotate and cannot push the liquid in the fixed box 20 into the driving tube 9. The cleaning cotton 5 is in a dry wiping state and is only used to clean the heat dissipating fin plate 3 and assist in accelerating the air flow.

[0028] When high-power heat dissipation is required, the driving mechanism drives the driving tube 9 to rotate at high speed, and the fixed disk 12 and the device box 13 rotate at high speed, so that the centrifugal force increases, gradually compressing the reset spring 18, so that the centrifugal block 16 releases the obstruction on one side of the through hole 15. At this time, the wind wheel 19 rotates at high speed to draw the liquid in the water tank 6 into the connecting pipe 23 through the third pipe 25, and then input it into the fixed box 20, and input it into the driving tube 9 through the through hole 15, the guide groove 17 and the connecting pipe 14, and finally output it to the cleaning cotton 5 through the first pipe 21 and the second pipe 22. During the rotation process, the cleaning cotton 5 applies the liquid to the surface of the heat dissipation fin plate 3, and takes away a large amount of heat through the volatilization of the liquid, thereby improving the heat dissipation efficiency. At the same time, the rotation speed of the fan blade 4 increases with the driving tube 9, which also greatly increases the flow rate of the gas entering and exiting the dustproof grille 36, further improving the heat dissipation efficiency.

[0029] Embodiment 2

[0030] See also Figure 2-Figure 7 , this embodiment further illustrates the first embodiment. The driving mechanism shown in the figure includes a driving motor 27 fixedly installed in the chassis body 1. The driving motor 27 is preferably of model YYHS-40. The output end of the driving motor 27 is coaxially fixedly connected with an output shaft 28. The top ends of the rotating rod 7 and the reciprocating screw rod 8 are coaxially fixedly connected with first bevel gears 29 respectively. Two groups of second bevel gears 30 respectively meshing with the first bevel gears 29 on both sides are coaxially fixedly connected to the output shaft 28. The rotating rod 7 is provided with a driving member for driving the driving tube 9 to rotate. The temperature warning controller 37 can control the operating state of the driving motor 27.

[0031] The driving member includes a third bevel gear 31 fixedly connected to one end of the driving tube 9 away from the fixed plate 12, the first lifting block 10 is rotatably connected to a fourth bevel gear 32 meshing with the third bevel gear 31, the rotating rod 7 passes through the fourth bevel gear 32, the outer wall of the rotating rod 7 is provided with a driving groove 33, and the inner wall of the fourth bevel gear 32 is fixedly connected to a driving block 34 slidably connected to the driving groove 33 along the vertical direction.

[0032] In this embodiment, the output shaft 28 is driven to rotate by the driving motor 27, so that the second bevel gear 30 drives the first bevel gears 29 on both sides to rotate, so that the rotating rod 7 and the reciprocating screw 8 can be rotated, and the rotating rod 7 drives the driving block 34 through the driving groove 33 to rotate the fourth bevel gear 32, and the fourth bevel gear 32 drives the third bevel gear 31 to rotate, so that the driving tube 9 can be rotated. The temperature warning controller 37 can synchronously control the operating speed of the driving motor 27 according to the temperature of the radiator 2. The higher the temperature, the faster the speed of the driving motor 27.

[0033] Embodiment 3

[0034] See also Figure 3-Figure 7 This embodiment further illustrates the first embodiment. The outer wall of the driving tube 9 shown in the figure is rotatably connected to multiple groups of cleaning blocks 35 that slide and fit with the outer wall of the heat dissipating fin plate 3 in the vertical direction. The multiple groups of cleaning blocks 35 are evenly distributed between adjacent fan blades 4.

[0035] In this embodiment, when the driving tube 9 is lifted and lowered along with the second lifting block 11 , the cleaning block 35 is driven to be lifted and lowered synchronously, so as to wipe the end surface of the heat dissipating fin plate 3 and reduce dust residue.
