Description

Technical Field

[0001] The present invention relates to the technical field of server chassis, and in particular to an anti-slip lock-type server chassis structure. Background Art

[0002] The server is a common communication system equipment, and the anti-slip lock type server chassis is a type of chassis designed specifically for servers. The chassis is equipped with anti-slip locks to simplify the steps of fixing the server in the rack and reduce the tedious operations of traditional screw fixing.

[0003] After searching, Chinese patent publication number CN119536468A discloses a high-efficiency heat dissipation server chassis shell, which relates to the technical field of server chassis. The high-efficiency heat dissipation server chassis shell includes a shell body and a filter screen. The shell body is also provided with a cleaning mechanism, which includes a cleaning frame and a drive assembly. The cleaning frame is provided with a plurality of bristles, which extend into the mesh of the filter screen. The drive assembly is used to drive the cleaning frame to move along the height direction of the filter screen, so that the bristles brush dust out of the mesh of the filter screen. The above solution has the effect of ensuring the heat dissipation effect of the chassis shell. The above patent still has shortcomings in actual use. Specifically, the server chassis proposed in the above solution adopts a fixed-mounted cooling fan. Although this design has a simple structure, it has some obvious disadvantages in actual application. Since the position and direction of the fan are fixed, the cooling airflow path inside the chassis is also relatively fixed, which may lead to insufficient flexibility and efficiency in cooling efficiency. When the internal hardware configuration of the server changes, such as the addition of high-power expansion cards or hard drives, or when the heat generation of certain components is particularly large, the fixed-position fan may not be able to specifically enhance local heat dissipation, resulting in heat accumulation in some areas, affecting the overall cooling effect.

[0004] Based on this, the present invention discloses an anti-slip lock-type server chassis structure. Summary of the Invention

[0008] In order to enable the frame and the plurality of strip baffles to automatically move upward and stagger the plurality of second heat dissipation ports, this solution designs a control component that drives the frame and the plurality of strip baffles to move upward by utilizing the downward movement of the lifting plate; As a further improvement of the present technical solution, a hole adapted to the drawstring is provided on the back of the chassis body for the drawstring to pass through.

[0009] As a further improvement of the present technical solution, the pushing assembly includes a groove, which is opened on the side of the lifting plate. A sliding rod is slidably arranged in the groove, and the sliding rod and the groove are connected by a spring. The end of the sliding rod extends to the outside of the groove and is fixed with a push block. The push block is provided with two inclined surfaces with opposite inclination directions. The push block is arranged opposite to the sliding frame. In the initial state, the push block is located above the sliding frame.

[0010] As a further improvement of the present technical solution, a first linear actuator is installed on the side of the chassis body, a slidable first slide is installed on the first linear actuator, a fixing plate is fixed to the side of the first slide, and the first linear actuator drives the first slide to move along the height direction of the chassis body; The back of the chassis body is provided with an air guide assembly for controlling the exhaust direction. The air guide assembly includes a guide frame, and a rotatable guide plate is provided inside the guide frame; A cooling assembly is provided on a side of the guide frame facing away from the chassis body. The cooling assembly includes a cooling seat, and a cooling module for cooling the gas is provided inside the cooling seat.

[0011] In order to improve the heat dissipation performance of the chassis, this solution designs an air guide component and a cooling component to provide low-temperature air to the interior of the chassis body; As a further improvement of the present technical solution, the guide frame is fixed on the side of the fixed plate, and an air outlet is opened on the side of the guide frame facing the chassis body.

This effectively avoids the "overheating" or "underheating" problems of traditional cooling systems and significantly improves energy efficiency. 2. The heat dissipation vents are opened and closed and the fan is positioned using purely mechanical structures such as the push block bevel, positioning slots, and tension springs. No electronic sensors or complex control systems are required, which not only reduces the failure rate and maintenance costs, but also ensures stable operation in harsh environments such as high temperature and electromagnetic interference. 3. The three-stage heat dissipation adopts the design of cooling module + spoiler blade + hose return, which cools the internal hot air flow and then reintroduces it into the key heating area to form a closed-loop refrigeration system, which is particularly suitable for continuous full-load operation in high-density computing scenarios.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0018] Existing chassis use fixed cooling fans for heat dissipation, but fixed fans have poor cooling flexibility and cannot adapt to hardware changes, which can easily lead to local overheating, low efficiency, inconvenient maintenance, and affect stability and energy efficiency.

[0019] To this end, the present invention provides a non-slip lock-type server chassis structure. Figure 1 As shown, it includes a chassis body 11, and a first exhaust area and a second exhaust area are provided on the back of the chassis body 11. The first exhaust area includes a plurality of first heat dissipation vents 13 distributed in a matrix, and the second exhaust area includes a plurality of second heat dissipation vents 14 distributed in a linear array. A dust screen is installed inside the chassis body 11, and the dust screen is arranged directly opposite the first exhaust area and the second exhaust area. A partition 12 is fixed inside the chassis body 11, and the partition 12 is located near the dust screen. The partition 12 divides the interior of the chassis body 11 into a heat dissipation area and a hard disk placement area. The hard disk placement area is used to place hard disks. The partition 12 is provided with a plurality of ventilation ducts so that hot air in the hard disk placement area can be discharged to the outside of the chassis body 11. See also Figure 1As shown, the chassis body 11 is provided with anti-slip locks for connecting the positioning plates 31, replacing the traditional screw connection to facilitate assembly and disassembly; See also Figure 10 As shown, a shielding assembly is provided on the back of the chassis body 11, and the shielding assembly includes a frame 15. A plurality of strip baffles 16 distributed in a linear array are fixed on the frame 15. In the initial state, the plurality of strip baffles 16 are respectively arranged opposite to the plurality of second heat dissipation openings 14. At this time, the plurality of strip baffles 16 respectively block the plurality of second heat dissipation openings 14. Guide blocks 17 are fixed on both sides of the frame 15. Two guide rods 18 are fixed on the back of the chassis body 11. The two guide blocks 17 are respectively slidably mounted on the two guide rods 18. When the frame 15 moves, the two guide blocks 17 and the two guide rods 18 provide a limit for it. See also Figure 2 As shown, a first linear actuator 19 is installed on the side of the chassis body 11. A slidable first slide is installed on the first linear actuator 19. A fixing plate 110 is fixed to the side of the first slide. The first linear actuator 19 drives the first slide to move along the height direction of the chassis body 11. See also Figure 3 As shown, a heat dissipation component is provided inside the chassis body 11, and the heat dissipation component is arranged in the heat dissipation area. The heat dissipation component includes a second linear actuator 21, and a slidable second slide is installed on the second linear actuator 21. A lifting plate 22 is fixed to the side of the second slide. Two mounting openings are provided on the lifting plate 22, and a heat dissipation fan 23 is installed in each of the two mounting openings. In the initial state, the two heat dissipation fans 23 are both arranged facing the first exhaust area. In this case, the two heat dissipation fans 23 are both located at the inner top position of the chassis body 11. When the two heat dissipation fans 23 are in operation, they can extract the hot air inside the chassis body 11 and discharge the hot air to the outside of the chassis body 11 through the plurality of first heat dissipation openings 13; See also Figure 6-Figure 8As shown, a control component is provided inside the chassis body 11, and the control component is used to control the position of the frame body 15. The control component includes a positioning plate 31, and positioning grooves 34 are provided at the upper and lower ends of the positioning plate 31. A sliding frame 32 is provided on the side of the positioning plate 31 for sliding. A slidable positioning block 33 is provided in the sliding frame 32, and the end position of the positioning block 33 is provided with two inclined surfaces with opposite inclined directions. In the initial state, the positioning block 33 is stuck in the positioning groove 34 at the upper end, and two slide grooves 37 are provided on the side of the sliding frame 32. Two sliders 38 are fixed on the side of the positioning block 33, and the two sliders 38 slide in the two slide grooves 37 respectively. The positioning block 33 is limited by two slide grooves 37 and two sliders 38 during a certain process. One of the sliders 38 is connected to the sliding frame 32 by a tension spring 39. Under the action of the tension spring 39, the positioning block 33 always has a tendency to move toward the positioning plate 31. A pull rope 36 is connected to the sliding frame 32. The end of the pull rope 36 away from the sliding frame 32 extends to the outside of the chassis body 11 and is connected to the frame 15. A hole adapted to the pull rope 36 is provided on the back of the chassis body 11 for the pull rope 36 to pass through. The upper and lower ends of the positioning plate 31 are fixed with first limit blocks 35. The sliding frame 32 is located between the two first limit blocks 35. See also Figure 9 As shown, a pushing assembly is provided on the side of the lifting plate 22, and the pushing assembly includes a groove 41. The groove 41 is opened on the side of the lifting plate 22. A slide rod 43 is slidably provided in the groove 41, and the slide rod 43 is connected to the groove 41 by a spring 42. The end of the slide rod 43 extends to the outside of the groove 41 and is fixed with a push block 44. The push block 44 is provided with two inclined surfaces with opposite inclined directions. The push block 44 is arranged opposite to the sliding frame 32. In the initial state, the push block 44 is located above the sliding frame 32. The server chassis proposed by the present invention has a three-level heat dissipation form. For the first level of heat dissipation, Figure 3 As shown, the lifting plate 22 is located at the upper limit position. At this time, the two cooling fans 23 are located at the inner top of the chassis body 11. In this case, the two cooling fans 23 can extract the hot air inside the chassis body 11 and discharge the hot air to the outside of the chassis body 11 through the plurality of first heat dissipation ports 13, thereby achieving a heat dissipation effect for the chassis body 11. The first-level heat dissipation is suitable for when the server is dormant or has no business load, the CPU utilization is low, and only basic system processes are running; For secondary heat dissipation, the second linear actuator 21 operates and drives the lifting plate 22 to move up and down inside the chassis body 11 via the second slide, causing the two cooling fans 23 to move up and down accordingly. During this process, the two cooling fans 23 can evenly and comprehensively extract heat from the chassis body 11 and discharge the heat through the plurality of second heat dissipation ports 14. In secondary heat dissipation, the up and down movement of the fans can cover a wider range, reduce heat dissipation blind spots, and improve heat dissipation efficiency. Secondary heat dissipation is suitable for the server's normal daytime business hours, when CPU utilization is moderate and routine tasks such as web page requests and database queries are processed. In the initial state, the server performs the first-level heat dissipation. At this time, the frame 15 is located at the lower limit position under the action of gravity. Figure 10 As shown in the left figure, in this case, a plurality of strip baffles 16 respectively block a plurality of second heat dissipation openings 14. When performing secondary heat dissipation, the lifting plate 22 first moves downward, and the control component controls the frame 15 and the plurality of strip baffles 16 to move upward until a heat dissipation zone is formed. Figure 10 In the state shown in the middle right figure, the plurality of strip baffles 16 are staggered with the plurality of second heat dissipation vents 14, and the heat inside the chassis body 11 can be discharged through the plurality of second heat dissipation vents 14. Through this design, only the first level of heat dissipation is enabled when the load is low or the temperature is low, reducing unnecessary air circulation and external dust intrusion, thereby reducing energy consumption and extending the life of the equipment. When the server performs secondary heat dissipation, the frame 15 and baffles move up to connect the second heat dissipation vents 14, significantly enhancing the heat dissipation capacity to cope with sudden heat. This structure not only optimizes the balance between heat dissipation efficiency and energy consumption, but also reduces dust accumulation during daily operation through physical shielding. For the control component, when the lifting plate 22 moves downward, the lifting plate 22 can drive the push block 44 to move downward through the slide rod 43, as shown in FIG. Figure 6As shown, during the downward movement of the push block 44, the inclined surface on it can push the sliding frame 32 downward. At this time, the elastic force applied by the tension spring 39 to the positioning block 33 cannot overcome the elastic force applied by the spring 42 to the slide rod 43, so that the slide rod 43 will not retract into the groove 41 under the obstruction of the sliding frame 32, and the thrust of the push block 44 can make the sliding frame 32 and the positioning block 33 move downward. The positioning block 33 is provided with two inclined surfaces with opposite inclined directions, and the shape of the positioning block 33 is adapted to the positioning groove 34. Therefore, when the positioning block 33 is subjected to the push block 44, the positioning block 33 is pushed downward. When the push force is applied, the inclined surface of the positioning block 33 will be squeezed against the groove wall of the positioning groove 34. Under the guiding action of the inclined surface, the positioning block 33 will retract into the sliding frame 32. Further, the pushing block 44 can drive the sliding frame 32 and the positioning block 33 to move downward. When the sliding frame 32 moves to a position where it contacts the first limit block 35 at the lower end, the positioning block 33 just moves to a position facing the positioning groove 34 at the lower end. At this time, the positioning block 33 will pop out under the elastic force of the tension spring 39 and be stuck in the positioning groove 34 at the lower end, thereby pushing the sliding frame 32. The first stop block 35 is used to stop the sliding frame 32 and the second stop block 35 is used to stop the sliding frame 32. The first stop block 35 is used to stop the sliding frame 32 and the second stop block 35 is used to stop the sliding frame 32. The first stop block 35 is used to stop the sliding frame 32 and the second stop block 35 is used to stop the sliding frame 32. The block 44 can drive the sliding frame 32 to move downward and position the sliding frame 32 to the bottom position of the positioning plate 31. When the sliding frame 32 moves downward, the sliding frame 32 can apply tension to the frame 15 through the pull rope 36, so that the frame 15 moves upward until the plurality of strip baffles 16 and the plurality of second heat dissipation openings 14 are in a mutually misaligned state. By setting a control component, the position of the frame 15 can be automatically adjusted, thereby realizing the automatic conduction of the plurality of second heat dissipation openings 14. The entire process is realized by mechanical transmission, and no additional control components are required. It should be noted that when the lifting seat moves up and resets, the push block 44 can also push the sliding frame 32 to move up and reset. The principle of this part is the same as the process of the push block 44 driving the sliding frame 32 to move down, and will not be described in detail here. Furthermore, in the secondary heat dissipation, the present invention also provides a targeted heat dissipation method. If a hard disk in the server is overloaded, that is, the temperature of a hard disk is too high and the heat generated is too large, the second linear actuator 21 can control the lifting plate 22 to move to a position facing the hard disk, thereby providing targeted heat dissipation for the hard disk generating excessive heat. It can be understood that when the lifting plate 22 moves to a position facing the second exhaust area, the push block 44 has moved to the bottom of the sliding frame 32, indicating that the plurality of strip baffles 16 are already in a position staggered with the plurality of second heat dissipation ports 14, thereby ensuring smooth secondary heat dissipation. See also Figure 11 and Figure 12 As shown, the back of the chassis body 11 is provided with an air guide assembly for controlling the exhaust direction. The air guide assembly includes a guide frame 51, which is fixed to the side of the fixing plate 110. A rotatable guide plate 53 is provided inside the guide frame 51. The guide frame 51 is provided with an air outlet 52 on the side facing the chassis body 11. One end of the guide plate 53 extends into the air outlet 52. A second limit block 54 is fixed to the inner surface of the guide frame 51. In the initial state, as shown in FIG. Figure 12 As shown, under the action of gravity, the guide plate 53 naturally falls on the second limit block 54. At this time, the end of the guide plate 53 close to the chassis body 11 is in contact with the top of the air outlet 52. The guide plate 53 controls the air flow to flow obliquely downward. The inner top surface of the guide frame 51 is provided with an electromagnet 55, and the electromagnet 55 is connected to the inner top surface of the guide frame 51 through a connecting piece. The connecting piece allows the electromagnet 55 to swing freely so that the guide plate 53 in the inclined state is adsorbed on the electromagnet 55. The guide plate 53 is made of magnetic material. When the electromagnet 55 is energized and magnetized, the electromagnet 55 provides magnetic attraction to the guide plate 53, causing the guide plate 53 to rotate and be adsorbed on the electromagnet 55, forming a Figure 11 The state shown, in this state, the end of the guide plate 53 close to the chassis body 11 is in contact with the bottom of the air outlet 52, and the guide plate 53 controls the air flow to flow obliquely upward; See also Figure 12 As shown, the connecting member includes two side ears and a vertical plate. The two side ears are fixed to the top surface of the electromagnet 55, and the vertical plate is fixed to the inner top surface of the guide frame 51. The vertical plate is rotatably installed between the two side ears, so that the two side ears and the electromagnet 55 can swing. For the air guide component, in the initial state, the electromagnet 55 is in a power-off state. At this time, the guide plate 53 naturally falls on the second limit block 54 under the action of gravity. The end of the guide plate 53 close to the chassis body 11 is in contact with the top of the air outlet 52. The guide plate 53 controls the air flow to flow obliquely downward. When performing secondary heat dissipation, the first linear actuator 19 and the second linear actuator 21 operate synchronously, so that the guide frame 51 moves synchronously with the lifting plate 22. That is, during the movement of the lifting plate 22 and the guide frame 51, the air outlet 52 is always arranged opposite the two cooling fans 23. Therefore, the gas discharged by the two cooling fans 23 can enter the air outlet 52 and be discharged obliquely downward under the guiding action of the guide plate 53. Figure 4 The status shown; The server chassis proposed in the present invention also has a three-stage heat dissipation function. The three-stage heat dissipation relies on the cooling component set on the fixed plate 110 to cool the air flow and re-discharge the cooled low-temperature gas into the interior of the chassis body 11. The three-stage heat dissipation is suitable for the working condition of the server overload operation. At this time, the CPU utilization rate is close to full load operation (such as scientific computing, stress testing, and high concurrency scenarios). In this case, the simple exhaust action may not be able to cope with the high heat generation phenomenon of the server. It is necessary to introduce low-temperature gas into the server. Specifically, see Figure 13 As shown, the cooling assembly includes a cooling seat 61, which is fixed to the side of the fixing plate 110, and the cooling seat 61 is located on one side of the guide frame 51. The cooling seat 61 is provided with an air duct 62 toward the side of the guide frame 51. When the electromagnet 55 is energized and attracts the guide plate 53 to rotate, the guide plate 53 can guide the airflow through the air duct into the interior of the cooling seat 61. A cooling module for cooling the gas is provided inside the cooling seat 61. The specific structure and working principle of the cooling module are prior art, which are not shown in the figure and will not be described in detail here. In an optional embodiment, the cooling module can use a semiconductor refrigeration plate (TEC) to directly actively cool the airflow through the Peltier effect, or a micro heat pipe array combined with a heat dissipation fin to efficiently conduct heat away using the phase change principle. A micro compressor refrigeration system can also be used. When the gas enters the interior of the cooling seat 61, the cooling module can quickly cool the gas. See also Figure 13 As shown, a spoiler blade 63 is fixed inside the cooling seat 61, and the cross section of the spoiler blade 63 is a spiral structure, as shown in FIG. Figure 13As shown, the end of the spoiler blade 63 is arranged opposite to the air channel 62. When the gas enters the cooling seat 61 through the air channel 62, the gas can flow along the spoiler blade 63 and finally flow into the inside of the spoiler blade 63. Both ends of the spoiler blade 63 are in contact with the inner surface of the cooling seat 61, so as to ensure that the gas can fully and comprehensively flow along the spoiler blade 63. Under the action of the spoiler blade 63, the flow time of the gas in the cooling seat 61 will be prolonged, and the time for the cooling module to act on the gas will be prolonged accordingly, so as to ensure the cooling effect of the cooling module on the gas and enable the gas to obtain sufficient cooling time. See also Figure 1 As shown, both ends of the cooling seat 61 are connected to a return pipe 64, and one end of the two return pipes 64 away from the cooling seat 61 is connected to the interior of the chassis body 11. The two return pipes 64 extend to the interior of the spoiler blade 63. When the gas flows into the interior of the spoiler blade 63, the gas will flow toward the two sides of the spoiler blade 63 and finally return to the interior of the chassis body 11 through the return pipe 64. Figure 13 The arrows in the figure show the direction of gas flow. This design can break through the ambient temperature limit and maintain stable hardware operation under extreme conditions of full-load CPU operation, effectively avoiding the risk of performance reduction or downtime due to overheating. At the same time, the heat dissipation efficiency is significantly improved by recycling the cold air, reducing the energy consumption introduced by the external cold air. It should be noted that the two return pipes 64 are both hoses, which can prevent the two return pipes 64 from hindering the up and down movement of the cooling seat 61; For three-stage heat dissipation, the electromagnet 55 is energized to generate magnetism, and at the same time, the cooling module inside the cooling seat 61 is running. When the electromagnet 55 is magnetized, it can attract the guide plate 53, so that the guide plate 53 guides the airflow to the air duct 62. Further, the gas enters the cooling seat 61, and the cooling module cools the gas. The cooled gas flows back to the interior of the chassis body 11 through the two return pipes 64, thereby providing low-temperature gas to the interior of the chassis body 11. It should be noted that the connection position between the two return pipes 64 and the chassis body 11 is located in the hard disk placement area. The purpose is to avoid the low-temperature gas flowing back into the chassis body 11 from being directly drawn away by the two cooling fans 23, so that the low-temperature gas has enough time to cool down the heat source such as the hard disk.

[0020] Working principle: The server chassis proposed in the present invention adopts a three-stage intelligent cooling system, which achieves efficient temperature control through dynamic mechanical structure and airflow management. In the initial first-stage cooling state, the lifting plate 22 is located at the top of the chassis, and the two cooling fans 23 are working directly towards the first cooling port 13, with only the basic exhaust mode turned on, which is suitable for low-load conditions. When the server enters a medium load, secondary cooling is triggered. The second linear actuator 21 drives the lifting plate 22 to move the fan up and down. At the same time, the control component automatically lifts the frame 15 through the mechanical linkage of the push block 44, the sliding frame 32, and the pull rope 36 to open the second heat dissipation port 14, achieving large-scale active heat dissipation. At this time, the deflector 53 guides the airflow downward under the action of gravity. If a local hard drive overheating is detected, the system can precisely position the fan to the heat source for targeted cooling. When the server is under full load, the third-level cooling is activated. The electromagnet 55 attracts the guide plate 53 to change the airflow path, allowing the hot air to enter the cooling seat 61 with integrated semiconductor refrigeration or micro-compressor. After the spiral spoiler blades 63 extend the heat exchange time, the hot air is fully cooled and finally sent back to the hard drive area through the soft return pipe 64 for recycling. The entire system achieves dynamic matching of heat dissipation intensity and load through modular design: first-level heat dissipation reduces standby energy consumption, second-level heat dissipation balances efficiency and coverage, and third-level heat dissipation breaks through ambient temperature limits to cope with extreme working conditions. Mechanical control components can open and close the heat dissipation ports and switch the diversion direction without additional sensors. The combination of cooling modules and return flow design not only avoids cold air short-circuiting but also improves heat exchange efficiency. It is particularly suitable for scenarios with strict requirements on heat dissipation reliability, such as high-density data centers.
