Description

Technical Field

[0001] This invention relates to the field of server rack heat dissipation technology, and in particular to a high-efficiency server rack heat dissipation mechanism. Background Technology

[0002] With the rapid development of information technology and power electronics industry, server racks, as the core carriers integrating servers, switches, frequency converters and various control components, have seen their internal power density continuously increase, resulting in huge heat accumulation during equipment operation. Traditional rack cooling methods mainly rely on passive natural cooling or simple axial fan forced air cooling, which has many inherent defects. Conventional fixed cooling fans can usually only cover airflow in one direction, making it difficult to adapt to the non-uniform heat source distribution inside the rack caused by different equipment installation positions. This can easily create heat dissipation dead corners in the corners of the rack or on the leeward side of the equipment, resulting in excessively high local hot spot temperatures, affecting the lifespan and operational stability of electronic components. Therefore, developing a high-efficiency heat dissipation mechanism for server racks that combines height adjustment and multi-directional airflow to solve existing problems such as uneven heat dissipation, poor adjustment flexibility, and high energy consumption has become an urgent need to improve the operational safety and reliability of server rack equipment. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency heat dissipation mechanism for server racks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency heat dissipation mechanism for a server rack includes a rack body. Guide rods are fixed between the inner walls of the top and bottom of the rack body. A lifting plate is movably connected to the outer walls of the two guide rods. A frame is welded to the side of the lifting plate. An air supply duct is movably connected to the inner wall of a through hole on the surface of the frame. A blower mechanism is installed on the top of the air supply duct. A second pulley is movably connected to the surface of the lifting plate. A nut is embedded in the inner surface of the second pulley. The second pulley is driven by a driving component. The nut and the lead screw assembly cooperate with each other. The second pulley and the air supply duct are transmitted through a transmission component.

[0005] As a further embodiment of the present invention: the blower mechanism includes an air plate welded to the top of the air supply pipe, a blower assembly connected to the bottom of the air supply pipe via a connector, a plurality of nozzles II being installed on the outer circumference of the air plate via a connector, and a bent pipe fixed to the top of the air plate via a connector, with a nozzle I welded to one end of the bent pipe.

[0006] As a further embodiment of the present invention: the blower assembly includes a blower fixed to the outer wall of the bottom of the cabinet and a telescopic corrugated pipe fixed to its output end.

[0007] As a further embodiment of the present invention: the connector includes an intermediate tube fixed to the bottom of the frame and a rotary joint connecting the intermediate tube and the air supply pipe, wherein the bottom of the intermediate tube and the top of the telescopic corrugated pipe are fixedly connected.

[0008] As a further embodiment of the present invention: a bracket is fixed to the top outer wall of the frame, and a vertical rod is fixed to the top inner wall of the bracket. An intermediate tube for use with the nozzle is fixed to the outer circumference of the vertical rod through a connecting rod.

[0009] As a further embodiment of the present invention: the lead screw assembly includes a lead screw movably connected between the top and bottom of the cabinet, and a self-locking motor for driving the lead screw is fixed to the outer wall of the top of the cabinet.

[0010] As a further embodiment of the present invention: the driving component includes a self-locking motor II fixed to the bottom outer wall of the lifting plate, and a pulley I is fixed to both the output end of the self-locking motor II and the top of the pulley II, and the two pulleys I are driven by a synchronous belt I.

[0011] As a further embodiment of the present invention: the transmission component includes a pulley three fixed to the outer circumference of the air supply pipe, and the pulley three and the pulley two are driven by a synchronous belt two.

[0012] As a further embodiment of the present invention: an exhaust fan is fixed to one side of the outer wall of the cabinet, and dustproof nets are installed on both sides of the exhaust fan.

[0013] As a further embodiment of the present invention: a temperature sensing probe and a processing component are respectively installed on the inner wall of one side of the cabinet.

[0014] Compared with the prior art, the present invention provides a high-efficiency heat dissipation mechanism for server racks, which has the following beneficial effects: 1. The closed-loop control system, consisting of a temperature sensing probe and a processing component, can monitor the temperature distribution in various areas within the cabinet in real time and accurately. When a temperature rise is detected and heat dissipation is required, the processing component quickly starts the blower, precisely delivering cool air to the air supply duct and air coil, and efficiently spraying it out through nozzles one and two. This effectively avoids equipment performance degradation or damage caused by localized overheating, ensuring the stable operation of electrical equipment within the cabinet.

[0015] 2. By using a self-locking motor to drive the lead screw or by using pulley one and synchronous belt one to drive pulley two and lead screw nut, and combining the transmission control of pulley two and pulley three by self-locking motor two, the lifting plate is raised and lowered along the guide rod and the air supply pipe is rotated. This allows the system to flexibly switch between heat dissipation modes. It can provide uniform airflow over a wide area at different heights and in different directions inside the cabinet to ensure overall temperature balance; it can also provide concentrated and powerful heat dissipation for specific electrical components with high heat generation, meeting the diverse heat dissipation needs of different working conditions and different electrical components.

[0016] 3. The external airflow formed by the exhaust fan and dust filter accelerates the discharge of hot air from the cabinet, enhancing heat exchange efficiency. Cold air enters from the intake end and hot air exits from the exhaust end, creating a continuous airflow circulation. This allows heat inside the cabinet to be quickly dissipated to the external environment. The dust filter effectively blocks external dust from entering the cabinet, preventing dust accumulation on electrical components, reducing equipment malfunctions and performance degradation caused by dust, extending equipment lifespan, and providing a good operating environment for the electrical equipment inside the cabinet.

[0017] 4. The closed-loop control system can precisely control the start-up, shutdown, and operating power of the blower and exhaust fan based on the actual temperature inside the cabinet. The cooling equipment is only activated when the temperature reaches the set threshold, avoiding unnecessary energy waste. By flexibly adjusting the blowing direction and range of the nozzles, effective temperature control inside the cabinet can be achieved with minimal energy consumption, improving energy efficiency, reducing equipment operating costs, and aligning with the development concept of energy conservation and environmental protection.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] A high-efficiency heat dissipation mechanism for server racks, such as Figures 1 to 7 As shown, the system includes a cabinet 1. A guide rod 9 is fixed between the inner top and bottom walls of the cabinet 1 by screws. A lifting plate 27 is slidably connected to the outer walls of the two guide rods 9. A frame 22 is welded to the side of the lifting plate 27. An air supply pipe 24 is rotatably connected to the inner wall of a through hole on the surface of the frame 22. An air plate 15 is welded to the top of the air supply pipe 24. A blower assembly is connected to the bottom of the air supply pipe 24 via a connector. Multiple sets of nozzles 26 are installed on the outer circumference of the air plate 15 via a connector. A bent pipe 28 is fixed to the top of the air plate 15 via a connector, and a nozzle 14 is welded to one end of the bent pipe 28. A bracket 13 is fixed to the outer top wall of the frame 22 by screws, and a vertical rod 29 is fixed to the inner top wall of the bracket 13 by screws. An intermediate pipe 20, which works with the nozzles 26, is fixed to the outer circumference of the vertical rod 29 via a connecting rod 25. The cabinet 1 is equipped with plates for fixing various electrical components. During operation, the electrical components generate heat and need to be dissipated to maintain their normal operation. When heat dissipation is required, the blower assembly can blow air into the air plate 15 through the air supply pipe 24. After the air enters the air plate 15, it is finally split by the second nozzle 26 in the circumferential direction of the air plate 15 and the first nozzle 14 on its top, so that the air can be blown out to different positions inside the cabinet 1. The air can be used to achieve large-scale air blowing and heat dissipation in different directions inside the cabinet 1. At the same time, since the lifting plate 27 can move up or down along the guide rod 9, the second nozzle 26 and the first nozzle 14 can blow air and dissipate heat at different heights inside the cabinet 1, so as to achieve uniform heat dissipation. When it is necessary to concentrate airflow to dissipate heat from electrical components at a certain height inside the cabinet 1, the direction of airflow from nozzle 14 in the circumferential direction can be adjusted. When nozzle 14 is rotated to face the electrical components and the middle tube 20 blocks the air inlet of nozzle 26, the airflow entering the air plate 15 is concentrated and sprayed out through nozzle 14. This increases the airflow while ensuring that the airflow is concentrated on the electrical components that need to be cooled, thus facilitating flexible heat dissipation according to actual operational needs.

[0023] The blower assembly includes a blower 8 fixed to the bottom outer wall of the cabinet 1 and a telescopic corrugated pipe 7 fixed to its output end. The connector includes an intermediate pipe 20 fixed to the bottom of the frame 22 and a rotary joint 21 connecting the intermediate pipe 20 and the air supply pipe 24. The bottom of the intermediate pipe 20 and the top of the telescopic corrugated pipe 7 are fixedly connected. When the blower 8 is started for heat dissipation, the blower 8 inputs air force into the middle pipe 20 through the telescopic corrugated pipe 7. The air force is input into the air supply pipe 24 through the rotary joint 21 and finally enters the air plate 15 to achieve air supply. The rotary joint 21 can ensure that the rotation of the air plate 15 will not affect the normal air supply.

[0024] A lead screw 10 is rotatably connected between the inner top wall and the inner bottom wall of the cabinet 1. A self-locking motor 4 is fixed to the outer top wall of the cabinet 1 by bolts, and the output end of the self-locking motor 4 is connected to the top of the lead screw 10 by a coupling. A pulley 18 is rotatably connected to the inner wall of the through hole on the surface of the lifting plate 27. A nut 12 that works with the lead screw 10 is embedded in the inner surface of the pulley 18. A self-locking motor 17 is fixed to the outer bottom wall of the lifting plate 27 by screws. A pulley 16 is fixed to both the output end of the self-locking motor 17 and the top of the pulley 18. The two pulleys 16 are driven by a synchronous belt 11. When the output of the self-locking motor 17 is in a self-locking state, the pulley 18 is also unable to rotate through the synchronous belt 11 and the pulley 16. Therefore, when the self-locking motor 4 drives the lead screw 10 to rotate, the lifting plate 27 is adjusted vertically under the guidance of the guide rod 9, so that the nozzle 14 moves to the set height after the orientation is adjusted to blow air and dissipate heat from the electrical components at the specific location.

[0025] The outer circumference of the air supply duct 24 is fixed with a pulley 23 by screws, and the pulley 23 and the pulley 18 are driven by a connecting rod 25. The transmission of pulley 218, synchronous belt 219 and pulley 323 causes self-locking motor 217 to indirectly drive air supply pipe 24 to rotate. During the rotation of air supply pipe 24, nozzle 26 located on the outer circumference of air plate 15 makes circular motion, so that nozzle 26 sprays air evenly along the circumference and avoids dead angles in the air outlet direction.

[0026] When the output of the self-locking motor 14 is in the self-locking state, the lead screw 10 is in a state where it cannot rotate. At this time, when the self-locking motor 27 indirectly drives the pulley 28 to rotate through the transmission of the synchronous belt 11 and the pulley 16, the pulley 28 drives the lead screw nut 12 to rotate relative to the lead screw 10 during the rotation process. Therefore, the lifting plate 27 moves vertically under the guidance of the guide rod 9 to achieve the height adjustment of the lifting plate 27. In addition, the self-locking motor 27 indirectly drives the air supply pipe 24 to rotate during this process. When it is necessary to achieve large-scale heat dissipation inside the cabinet 1, the multiple sets of nozzles 26 installed on the outer circumference of the air plate 15 blow air in a circular motion to achieve large-scale heat dissipation inside the cabinet 1. Meanwhile, since the outer diameter of pulley 218 is larger than that of pulley 323, when pulley 218 drives the nut 12 to rotate at a relatively low speed, the air supply pipe 24 can drive the air plate 15 to rotate at a higher speed, so that nozzle 226 and nozzle 14 can deliver air at a higher frequency, thereby improving the uniformity of air blowing.

[0027] An exhaust fan 2 is fixed to one side of the outer wall of the cabinet 1 by screws, and dustproof nets 3 are installed on both sides of the exhaust fan 2; By installing an exhaust fan 2, exhaust can be achieved while the blower 8 is blowing air, thereby ensuring that the air inside the cabinet 1 is in an external circulation state, avoiding heat accumulation inside the cabinet 1 and preventing heat exchange between the inside and outside. The dustproof net 3 can prevent dust and improve protection at the same time.

[0028] Temperature sensing probes 5 and processing components 6 are respectively installed on the inner wall of one side of the cabinet 1; Temperature sensor 5 collects temperature data of various areas inside cabinet 1 in real time and transmits it to processing component 6. Processing component 6 analyzes and judges the temperature signal. When it detects that the local or overall temperature exceeds the preset threshold, it automatically triggers the start of blower 8 and exhaust fan 2. Based on the temperature distribution, it intelligently controls the operation of self-locking motor 1 4 and self-locking motor 2 17, adjusts the height of lifting plate 27 and the orientation and rotation speed of nozzle 1 14 and nozzle 2 26, so as to achieve precise and concentrated heat dissipation of high-heat areas or large-scale uniform cooling of the entire cabinet, thereby completing the closed-loop control from temperature monitoring to dynamic heat dissipation regulation.

[0029] Working principle: The temperature distribution inside the cabinet 1 is monitored and analyzed in real time by the temperature sensing probe 5 and the processing component 6. When heat dissipation is required, the processing component 6 starts the blower 8 to deliver air to the air supply pipe 24 and air plate 15 through the telescopic corrugated pipe 7, the intermediate pipe 20 and the rotary joint 21, and finally sprayed out by the nozzle 14 and the nozzle 26. The self-locking motor 14 drives the lead screw 10 or drives the pulley 28 and the lead screw nut 12 through the pulley 16 and the synchronous belt 11. Combined with the transmission control of the self-locking motor 217 on the pulley 28 and the pulley 3 23, the lifting plate 27 is lifted and lowered along the guide rod 9 and the air supply pipe 24 is rotated. This allows for flexible switching between the nozzles to blow air evenly over a wide range at different heights and directions inside the cabinet 1 or to concentrate and strongly dissipate heat for specific electrical components. At the same time, it works with the exhaust fan 2 and the dust filter 3 to form an external circulation airflow.
