Description

Technical Field

[0001] This invention relates to the field of electrical component technology, specifically to a heat dissipation chassis with a temperature warning function. Background Technology

[0002] Printed circuit boards utilize photolithography, where a photographic image is etched onto a copper or zinc plate, which is then used for printing. This represents a significant advancement over traditional circuit boards. During operation, the heat dissipation of components in printed circuit equipment greatly affects the overall stability and lifespan of the equipment; therefore, the heat dissipation enclosure is a crucial component within the device.

[0003] Existing heat dissipation chassis mostly use heat sinks with heat dissipation fins for heat dissipation. During the heat dissipation process, dust easily accumulates on the surface of the fins. If they are not cleaned for a long time, the heat dissipation efficiency will be affected. At the same time, the heat dissipation efficiency is relatively fixed when relying solely on the fins. When operating at high power, it is difficult to significantly improve the heat dissipation efficiency of the equipment through the heat dissipation fins, and the heat dissipation effect is not ideal.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figures 1-8 The diagram shows a heat dissipation chassis with a temperature warning function, comprising a chassis body 1, a heat dissipation mechanism, an auxiliary mechanism, and a drive mechanism. A radiator 2 for conducting and transferring heat is fixedly connected inside the chassis body 1. The radiator 2 has multiple sets of heat dissipation fins 3. A temperature warning controller 37 for sensing temperature and providing warning control is fixedly connected to the radiator 2. A dustproof grille 36 is fixedly connected to the side of the chassis body 1. The heat dissipation mechanism includes multiple sets of fan blades 4 installed between adjacent heat dissipation fins 3. Cleaning cotton 5 is fixedly connected to both sides of each fan blade 4, used to drive the fan blades 4 to rotate during heat dissipation, assisting the airflow inside the chassis body 1 while cleaning the sides of the heat dissipation fins 3. The auxiliary mechanism includes a water tank 6 fixedly installed inside the chassis body 1, used to assist in drawing liquid from the water tank 6 into the fan blades 4 when high-power heat dissipation is required, and then applying it to the surface of the heat dissipation fins 3 through the cleaning cotton 5 to improve the efficiency of evaporative heat dissipation. The drive mechanism is installed inside the chassis body 1 to drive the fan blades 4 to run, performing comprehensive cleaning and auxiliary heat dissipation on the heat dissipation fins 3.

[0029] The heat dissipation mechanism also includes a rotating rod 7 and a reciprocating screw 8 rotatably connected to the water storage tank 6. A drive tube 9 is provided between the rotating rod 7 and the reciprocating screw 8. Multiple sets of fan blades 4 are evenly fixedly installed on the outer wall of the drive tube 9. The two ends of the drive tube 9 are respectively rotatably connected to a first lifting block 10 and a second lifting block 11. The rotating rod 7 passes through the first lifting block 10 and is movably connected to the inner wall of the first lifting block 10. The reciprocating screw 8 passes through the second lifting block 11 and is threadedly connected to the second lifting block 11. The drive mechanism is used to drive the drive tube 9 and the reciprocating screw 8 to rotate.

[0030] The auxiliary mechanism also includes a fixed disk 12 and a device box 13 that are rotatably connected to the inner wall of the second lifting block 11. One end of the drive tube 9 is coaxially fixedly connected to the fixed disk 12, and the device box 13 is coaxially fixedly connected to the fixed disk 12. A connecting pipe 14 connected to one end of the drive tube 9 is provided on the fixed disk 12. A through hole 15 that can be connected to the connecting pipe 14 is provided on the side of the device box 13. A control component is provided inside the device box 13 to control the connection state between the through hole 15 and the connecting pipe 14 according to the rotation speed of the drive tube 9.

[0031] The control components include multiple centrifugal blocks 16 installed in the device box 13. Multiple guide grooves 17 are provided in the device box 13. The connecting pipe 14 and the through hole 15 are connected to the guide grooves 17. The centrifugal blocks 16 are slidably connected to the inner wall of the guide grooves 17. One end of the centrifugal block 16 is fixedly connected to a return spring 18 that is fixedly connected to the guide groove 17. The device box 13 is provided with a conveying component for liquid pumping.

[0032] The conveying component includes a fan wheel 19 fixedly installed on the side of the device box 13, a fixed box 20 fixedly connected inside the second lifting block 11, the outer wall of the fan wheel 19 being rotatably connected to the inner wall of the fixed box 20, multiple sets of first pipes 21 being evenly opened on the outer wall of the drive pipe 9, multiple sets of second pipes 22 being evenly opened inside the fan blade 4 and connected to the first pipes 21, and a connecting pipe 23 connected to the water storage tank 6 being connected to the fixed box 20.

[0033] The conveying component also includes a pulling block 24 that is slidably connected to the inner wall of the water storage 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 storage tank 6 and slides against the water storage tank 6. A third pipe 25 for connecting the connecting pipe 23 and the water storage tank 6 is provided inside the pulling block 24. A tension spring 26 that is fixedly connected to the inner wall of the water storage tank 6 is fixedly connected to the side of the pulling block 24.

[0034] In this embodiment, during the operation of the printed circuit, the heat from the equipment components is transferred to the heat dissipation fins 3 through the heat sink 2 inside the chassis body 1. The temperature of the heat sink 2 is monitored and warned by the temperature warning controller 37. When the temperature exceeds the set temperature, the drive mechanism drives the drive tube 9 to rotate, and the drive tube 9 drives the fan blade 4 to rotate. The fan blade 4 is arc-shaped. During the rotation, it helps to accelerate the airflow through the heat dissipation fins 3, improve the heat transfer efficiency, and thus accelerate heat dissipation. At the same time, during the rotation of the fan blade 4, the cleaning cotton 5 on both sides will wipe and clean the heat dissipation fins 3 on both sides.

[0035] It is worth noting that the drive mechanism synchronously drives the reciprocating screw 8 to rotate, thereby causing the second lifting block 11 to drive the drive tube 9 and the first lifting block 10 to reciprocate and lift together, so as to achieve the purpose of comprehensive cleaning and auxiliary heat dissipation of the entire heat dissipation fin 3. During the lifting process, the tension spring 26 will continuously pull the pulling block 24, so that the connecting tube 23 will remain in a taut state.

[0036] When the operating power is low, the operating speed of the drive mechanism is low, and the drive tube 9 rotates slowly. At this time, the fixed plate 12 and the device box 13 rotate slowly, and the centrifugal block 16 is subjected to a small centrifugal force. The centrifugal block 16 will continuously block one end of the through hole 15, so that the through hole 15 and the connecting pipe 14 are not connected. At this time, the device box 13 drives the fan wheel 19 to rotate, but cannot push the liquid in the fixed box 20 into the drive tube 9. The cleaning cotton 5 is in a dry wiping state and is only used to clean the heat dissipation fins 3 and assist in accelerating airflow.

[0037] When high-power heat dissipation is required, the drive mechanism drives the drive tube 9 to rotate at high speed. The fixed plate 12 and the device box 13 rotate at high speed, which increases the centrifugal force and gradually compresses the return spring 18, so that the centrifugal block 16 releases the obstruction on one side of the through hole 15. At this time, the fan wheel 19 rotates at high speed and draws the liquid in the water storage tank 6 into the connecting pipe 23 through the third pipe 25, and then into the fixed box 20. It is then input into the drive tube 9 through the through hole 15, the guide groove 17 and the connecting pipe 14, and finally output into the cleaning cotton 5 through the first pipe 21 and the second pipe 22. During the rotation, the cleaning cotton 5 applies the liquid to the surface of the heat dissipation fins 3. The liquid evaporates and carries away a large amount of heat, improving the heat dissipation efficiency. At the same time, as the speed of the fan blade 4 increases with the increase of the drive tube 9, the flow rate of the gas entering and exiting through the dustproof grille 36 also increases significantly, further improving the heat dissipation efficiency.

[0038] Example 2

[0039] Please see Figures 2-7 This embodiment further illustrates Embodiment 1. The drive mechanism shown in the figure includes a drive motor 27 fixedly installed inside the chassis body 1. The drive motor 27 is preferably a YYHS-40. The output end of the drive motor 27 is coaxially fixedly connected to an output shaft 28. The top ends of the rotating rod 7 and the reciprocating lead screw 8 are respectively coaxially fixedly connected to a first bevel gear 29. Two sets of second bevel gears 30 are coaxially fixedly connected to the output shaft 28, respectively meshing with the first bevel gears 29 on both sides. The rotating rod 7 is provided with a drive component for driving the drive tube 9 to rotate. The temperature warning controller 37 can control the operating status of the drive motor 27.

[0040] The driving component includes a third bevel gear 31 fixedly connected to the end of the driving tube 9 away from the fixed disk 12, a fourth bevel gear 32 rotatably connected to the first lifting block 10 and meshing with the third bevel gear 31, a rotating rod 7 passing through the fourth bevel gear 32, a driving groove 33 being provided on the outer wall of the rotating rod 7, and a driving block 34 being fixedly connected to the inner wall of the fourth bevel gear 32 and slidingly connected to the driving groove 33 in the vertical direction.

[0041] In this embodiment, the output shaft 28 is rotated by the drive motor 27, which causes the second bevel gear 30 to drive the first bevel gears 29 on both sides to rotate, thereby causing the rotating rod 7 and the reciprocating screw 8 to rotate. The rotating rod 7 drives the drive block 34 through the drive groove 33, causing the fourth bevel gear 32 to rotate. The fourth bevel gear 32 drives the third bevel gear 31 to rotate, thereby causing the drive tube 9 to rotate. The temperature warning controller 37 can synchronously control the running speed of the drive motor 27 according to the temperature of the radiator 2. The higher the temperature, the faster the speed of the drive motor 27.

[0042] Example 3

[0043] Please see Figures 3-7 This embodiment further illustrates Embodiment 1. In the figure, the outer wall of the drive tube 9 is rotatably connected to multiple sets of cleaning blocks 35 that slide and adhere to the outer wall of the heat dissipation fin 3 in the vertical direction. The multiple sets of cleaning blocks 35 are evenly distributed between adjacent fan blades 4.

[0044] In this embodiment, when the drive tube 9 moves up and down with the second lifting block 11, it will drive the cleaning block 35 to move up and down synchronously, thereby wiping the end face of the heat dissipation fins 3 and reducing dust residue.
