Abstract
Description
Technical Field
[0001] This invention belongs to the field of chassis technology, specifically a high-efficiency heat dissipation mechanism for information system operation and maintenance chassis. Background Technology
[0002] Information system maintenance chassis are the core physical carriers of modern data centers, integrating key hardware such as servers, network equipment, and power modules. Their design emphasizes high-density layout, heat dissipation, and modular expansion to ensure continuous and stable system operation. Chassis typically integrate intelligent management modules, supporting remote monitoring, fault early warning, and power dispatching. They serve as the foundational hardware platform for automated operation and maintenance and rapid response; their reliability and manageability directly affect the continuity of information system services and operational efficiency.
[0003] Currently, information system maintenance chassis generally adopt a multi-directional collaborative active cooling design. Specifically, air intake grilles are usually installed on both sides of the chassis to draw in cool air from the environment. After passing through heat-generating modules (such as servers and switches) inside the chassis, the heated air is driven by fans inside the chassis and efficiently exhausted from the corresponding exhaust vents, forming a directional airflow that can exchange with the air inside the chassis for active cooling.
[0004] However, current cooling solutions have a significant bottleneck. When high-performance components inside the server enter a high-load state and generate localized peak heat, the limitations of traditional fixed fan layouts become apparent. These fans are installed on specific airflow channels in the chassis, and their position and speed strategies are usually preset based on the overall average cooling demand. Therefore, the system cannot dynamically adjust the physical position of the fans or concentrate the airflow, and cannot "precisely deliver air" to sudden high heat sources. This results in localized overheated areas not receiving the most direct and efficient cooling, and the heat exchange efficiency is not maximized, which may restrict the continuous release of component performance and create potential thermal instability risks.

[0009] The connecting assembly includes a circular groove formed on the top surface of the second lead screw, in which a disk is slidably connected. A third spring is fixedly connected between the bottom surface of the inner wall of the circular groove and the disk, and an electromagnet that repels the disk is provided on the bottom surface of the circular groove. A pair of slots are formed on the bottom surface of the first lead screw, and a pair of levers that engage with the slots are fixedly connected to the top surface of the disk.
[0010] A connecting sleeve is provided on the side of the slider away from the second motor.

[0012] The outer wall of the connecting sleeve is provided with a hollow elastic block that communicates with the second cavity. A conduit connects the second cavity and the first cavity.

[0016] The beneficial effects of this invention are as follows: 1. This invention utilizes a first motor to drive a first lead screw to rotate. The lead screw then controls a guide rail to move, bringing it to a position flush with the high-temperature component. Subsequently, it controls a slider to move to the position of the high-temperature component. Afterward, a second motor is activated, causing the shaft to rotate at high speed. This generates airflow from the fan blades to dissipate heat from the high-temperature component, significantly improving heat dissipation efficiency and allowing the high-temperature component to operate under normal temperature conditions, thus ensuring the stability of the information system.
[0017] 2. This invention allows the coolant inside the connecting sleeve to absorb heat emitted by high-temperature components. Simultaneously, it can inject air into the first cavity. This air pushes the magnetic block, causing it to push the coolant from the first cavity into the second cavity. The elastic block then expands. As the magnetic block moves closer to the first spring, the coolant in the second cavity flows back into the first cavity, thus keeping the coolant in a flowing state and further improving its heat absorption effect on the high-temperature components.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] Example 1: As Figures 1 to 7As shown in the embodiment of the present invention, a high-efficiency heat dissipation mechanism for an information system maintenance chassis includes a chassis 1. A set of air inlets 2 are provided on one side of the chassis 1, and a set of air outlets 3 are provided on the side of the chassis 1 away from the air inlets 2. A first connecting plate 4 is fixedly connected to the inner wall of the chassis 1. A first lead screw 5 is rotatably connected to the bottom surface of the first connecting plate 4, and a first motor for driving the first lead screw 5 to rotate is provided on the top surface of the first connecting plate 4. A guide rail 6 is threadedly connected to the surface of the first lead screw 5, and the side wall of the guide rail 6 is connected to the inner wall of the chassis 1. The guide rail 6 has a sliding connection with the wall. A first groove 7 is provided on one side of the guide rail 6. A slider 8 is slidably connected to the inner wall of the first groove 7. A moving mechanism for controlling the movement of the slider 8 is provided on the guide rail 6. A rotating shaft 9 is rotatably connected inside the slider 8. A set of fan blades 10 is fixedly connected to the surface of the rotating shaft 9. A second groove 20 is provided on the side of the guide rail 6 away from the first groove 7. The second groove 20 communicates with the first groove 7. A second motor for driving the rotating shaft 9 to rotate is fixedly connected to the slider 8 through a bracket. The bracket passes through the second groove 20. The housing 1 of this application houses various components and is equipped with a fan for internal heat dissipation. If some high-performance components enter a high-load state and generate localized peak heat, the first motor drives the first lead screw 5 to rotate. The first lead screw 5 then controls the guide rail 6 to move, so that the guide rail 6 moves to a position flush with the high-temperature component. Subsequently, the sliding block 8 is moved by the moving mechanism, so that the sliding block 8 moves to the position of the high-temperature component. Then, the second motor is started, causing the rotating shaft 9 to rotate at high speed, thereby causing the fan blades 10 to generate airflow to dissipate heat from the high-temperature component, greatly improving the heat dissipation efficiency and allowing the high-temperature component to work in a normal temperature environment, ensuring the stability of the information system operation.
[0023] The moving mechanism includes an air injection component and a moving component. The moving component includes a first cavity 11 formed within the guide rail 6. A magnetic block 12, which is magnetically attracted to the slider 8, is slidably connected within the first cavity 11. A first spring is fixedly connected between the side of the magnetic block 12 near the first lead screw 5 and the inner wall of the first cavity 11. The air injection component is used to inject air into the first cavity 11 to push the magnetic block 12 to move. When it is necessary to control the movement of the slider 8, the air injection component can be used to inject air into the first cavity 11, causing the gas to push the magnetic block 12 to move away from the first lead screw 5. At this time, the magnetic block 12 will drive the slider 8 to move, causing the slider 8 to move the fan blade 10 to the high-temperature component. Then, the air injection is stopped, and the fan blade 10 is allowed to rotate at high speed to efficiently dissipate heat from the high-temperature component.
[0024] The air injection assembly includes a second connecting plate 13 fixed to the inner wall of the housing 1, a fixing block 15 fixedly connected to the second connecting plate 13, an opening at the top of the fixing block 15, a push block 16 slidably connected inside the fixing block 15, a second spring fixedly connected between the bottom surface of the push block 16 and the inner wall of the fixing block 15, a first connecting pipe 18 communicating with the inside of the fixing block 15, a second connecting pipe 19 communicating inside the cavity, and a flexible hose connecting the first connecting pipe 18 and the second connecting pipe 19, a third lead screw rotatably connected to the bottom surface of the inner wall of the housing 1, a pressure plate 17 threadedly connected to the surface of the third lead screw, the side wall of the pressure plate 17 fitting against the inner wall of the housing 1, and a connecting assembly between the first lead screw 5 and the second lead screw 14. In this application, when the slider 8 needs to be controlled, the connecting assembly first connects the second lead screw 14 and the first lead screw 5. Then, the first lead screw 5 rotates, causing the second lead screw 14 to rotate. At this time, the pressure plate 17 moves downward, thereby pushing the push block 16. The push block 16 then pushes the gas in the fixed block 15, allowing the gas to enter the first cavity 11 through the pipe and push the magnetic block 12 to move, thereby controlling the slider 8 to move. After the slider 8 moves to the appropriate position, the connecting assembly is no longer connected between the first lead screw 5 and the second lead screw 14. Then, the guide rail 6 is controlled to move. When the slider 8 needs to be reset, it is only necessary to reverse the first lead screw 5 when it is connected to the second lead screw 14. At this time, the pressure plate 17 moves upward, causing the second spring to push the push block 16 upward. At the same time, the first spring also pulls the magnetic block 12 to reset.
[0025] The connecting assembly includes a circular groove 21 formed on the top surface of the second lead screw 14, in which a disk 24 is slidably connected. A third spring is fixedly connected between the bottom surface of the inner wall of the circular groove 21 and the disk 24. An electromagnet 25 repelling the disk 24 is provided on the bottom surface of the circular groove 21. A pair of slots 23 are formed on the bottom surface of the first lead screw 5, and a pair of locking rods 22 that engage with the slots 23 are fixedly connected to the top surface of the disk 24. When it is necessary to connect the first lead screw 5 and the second lead screw 14, this application can... When the electromagnet 25 is activated, it pushes the disk 24, causing the disk 24 to move the locking lever 22 upward. Then, when the first lead screw 5 rotates, the locking lever 22 aligns with the slot 23 and engages with it. This allows the first lead screw 5 to drive the second lead screw 14 to rotate synchronously. When the electromagnet 25 is deactivated, the third spring pulls the disk 24 to reset, causing the locking lever 22 to disengage from the slot 23. At this point, the first lead screw 5 will not drive the second lead screw 14 to rotate.
[0026] A connecting sleeve 26 is provided on the side of the slider 8 away from the second motor. A set of air inlets 28 is provided on the side of the connecting sleeve 26 closest to the second motor, and a set of air outlets 27 is provided on the side of the connecting sleeve 26 away from the air inlets 28. A second cavity 29 is provided inside the connecting sleeve 26, and coolant is stored in the second cavity 29. When the fan blade 10 is working, gas enters from the air inlets 28 and is then discharged from the air outlets 27 onto the high-temperature components. At the same time, the fan blade 10 contacts the high-temperature components through the connecting sleeve 26. At this time, the coolant in the connecting sleeve 26 can absorb heat, thereby further improving the heat dissipation efficiency of the high-temperature components.
[0027] The slider 8 has a third groove 33, and the rotating shaft 9 is located within the third groove 33. A ring 32 is slidably connected to the inner wall of the third groove 33. A fourth spring is fixedly connected between the side of the ring 32 closest to the second motor and the inner wall of the third groove 33. A pair of connecting rods 34 are fixedly connected between the side of the ring 32 away from the fourth spring and the connecting sleeve 26. The connecting sleeve 26 is made of elastic material. Since different parts have different sizes, the connecting sleeve 26 cannot completely fit with all parts. In this case, the above mechanism can push the ring 32 with the help of the fourth spring, so that the ring 32 drives the connecting rods 34 to move. Then the connecting rods 34 will drive the connecting sleeve 26 to move, so that it can fit with all parts for heat conduction.
[0028] The outer wall of the connecting sleeve 26 is provided with a hollow elastic block 31 that communicates with the second cavity 29. A conduit 30 connects the second cavity 29 and the first cavity 11. The first cavity 11 stores coolant, which is located on the side of the magnetic block 12 away from the first spring. When cooling high-temperature components, the present application allows the gas injection assembly to inject gas into the first cavity 11, and then allows the gas injection assembly to remove the gas from the first cavity 11, allowing the magnetic block 12 to move within a certain range. When the magnetic block 12 moves away from the first spring, it pushes the coolant in the first cavity 11 into the second cavity 29. At this time, the elastic block 31 expands. When the magnetic block 12 moves closer to the first spring, the coolant in the second cavity 29 flows back into the first cavity 11, thereby keeping the coolant in a flowing state to further improve the heat absorption effect of the coolant on the high-temperature components.
[0029] Example 2: Figures 8 to 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a fixed frame 35 is fixedly connected to the inner wall of the air inlet 2, and a filter screen 36 is fixedly connected to the inner wall of the fixed frame 35; in this application, when the fan and the blades 10 of the housing 1 rotate, air will be introduced from the air inlet 2. At this time, the filter screen 36 can be used to filter impurities in the gas to prevent dust from entering the housing 1 and accumulating on the components, which would affect the heat dissipation performance of the components themselves.
[0030] A fixing rod 42 is fixedly connected to the bottom surface of the connecting sleeve 26. A hollow block 37 is fixedly connected to the end of the fixing rod 42 away from the slider 8. A set of brush bristles 39 for cleaning the filter screen 36 is provided on the hollow block 37. In this application, the guide rail 6 can be moved up and down by the first lead screw 5. The slider 8 can be moved by the air injection component. The movement of the slider 8 will drive the connecting sleeve 26 to move, thereby driving the hollow block 37 to move. At this time, the hollow block 37 will drive the brush bristles 39 to move. The brush bristles 39 are fine bristles that can pass through the mesh of the filter screen 36 to clean the dust on the outer and inner sides of the filter screen 36, so as to avoid dust accumulation affecting the air intake efficiency.
[0031] A sliding plate 38 is slidably connected inside the hollow block 37. A fifth spring is fixedly connected between the side of the sliding plate 38 away from the filter screen 36 and the inner wall of the hollow block 37. The brush bristles 39 are fixedly connected to the sliding plate 38. A set of circular holes corresponding to the brush bristles 39 are opened on the side of the hollow block 37 near the brush bristles 39. The brush bristles 39 pass through the circular holes. A set of magnetic sheets 40 are fixedly connected to the side of the sliding plate 38 near the brush bristles 39. A set of magnetic strips 41 that are magnetically attracted to the magnetic sheets 40 are fixedly connected to the inner wall of the air inlet 2. When the hollow block 37 moves to the air inlet 2, the magnetic strips 41 will attract the magnetic sheets 40, causing the magnetic sheets 40 to drive the sliding plate 38 to move. At this time, the brush bristles 39 will come into contact with the filter screen 36. At the same time, the sliding plate 38 will push the gas inside the hollow block 37. The gas will be discharged from the circular holes and blown onto the brush bristles 39 and the filter screen 36 to remove dust and impurities on the brush bristles 39 and the filter screen 36.
[0032] Working principle: The first motor drives the first lead screw 5 to rotate, which in turn controls the guide rail 6 to move to a position flush with the high-temperature component. Then, the moving mechanism controls the slider 8 to move to the position of the high-temperature component. After that, the second motor is started, which drives the rotating shaft 9 to rotate at high speed, thereby generating airflow from the fan blades 10 to dissipate heat from the high-temperature component, greatly improving the heat dissipation efficiency and allowing the high-temperature component to operate in a normal temperature environment, ensuring the stability of the information system. When it is necessary to control the slider 8 to move, the first cavity 11 can be injected with air using the air injection component. The gas pushes the magnetic block 12 to move away from the first lead screw 5. At this time, the magnetic block 12 will drive the slider 8 to move, which in turn drives the fan blades 10 to the high-temperature component. Then, the air injection stops, and the fan blades 10 rotate at high speed to efficiently dissipate heat from the high-temperature component. In this application, when controlling the slider 8, the connecting assembly first connects the second lead screw 14 and the first lead screw 5. Then, the first lead screw 5 rotates, causing the second lead screw 14 to rotate. At this time, the pressure plate 17 moves downward, pushing the push block 16. The push block 16 then pushes the gas inside the fixed block 15, allowing the gas to enter the first cavity 11 through a pipe and push the magnetic block 12 to move, thereby controlling the movement of the slider 8. After the slider 8 moves to the appropriate position, the connecting assembly disconnects the first lead screw 5 and the second lead screw 14. Then, the guide rail 6 is moved. When the slider 8 needs to be reset, it is only necessary to reverse the first lead screw 5 when it is connected to the second lead screw 14. When the pressure plate 17 moves upward, the second spring pushes the push block 16 upward, and the first spring pulls the magnetic block 12 to reset. When it is necessary to connect the first lead screw 5 and the second lead screw 14, the electromagnet 25 is activated to push the disk 24, which in turn drives the locking lever 22 upward. Then, when the first lead screw 5 rotates, the locking lever 22 aligns with the slot 23 and engages with it, so that when the first lead screw 5 rotates, it can drive the second lead screw 14 to rotate synchronously. When the electromagnet 25 is turned off, the third spring pulls the disk 24 to reset, so that the locking lever 22 disengages from the slot 23. At this time, when the first lead screw 5 rotates, it will not drive the second lead screw 14 to rotate. When the fan blade 10 is working, gas enters through the air inlet 28 and is then discharged through the air outlet 27 onto the high-temperature components. At the same time, it comes into contact with the high-temperature components through the connecting sleeve 26. At this time, the coolant in the connecting sleeve 26 can absorb heat, thereby further improving the heat dissipation efficiency of the high-temperature components. Since different components have different sizes, the connecting sleeve 26 cannot completely fit with all components. At this time, the above mechanism can push the ring 32 with the fourth spring, so that the ring 32 drives the connecting rod 34 to move. Then the connecting rod 34 will drive the connecting sleeve 26 to move, so that it can fit with all components for heat conduction. When cooling high-temperature components, this application allows the gas injection assembly to inject gas into the first cavity 11, and then the gas injection assembly to remove the gas from the first cavity 11, allowing the magnetic block 12 to move within a certain range. When the magnetic block 12 moves away from the first spring, it pushes the coolant in the first cavity 11 into the second cavity 29. At this time, the elastic block 31 expands. When the magnetic block 12 moves closer to the first spring, the coolant in the second cavity 29 flows back into the first cavity 11, thus keeping the coolant in a flowing state to further improve the heat absorption effect of the coolant on the high-temperature components.
