Description

Technical Field

[0001] This invention relates to the field of 2U storage server technology, specifically to a multi-bay 2U storage server chassis with an optimized compartmentalized structure. Background Technology

[0002] As we all know, with the rapid development of cloud computing, big data and artificial intelligence technologies, the requirements for storage density and computing performance of data centers are increasing day by day. As the mainstream configuration of data centers, the structural design of the hard drive bay of 2U storage servers is directly related to storage capacity, heat dissipation performance and maintenance convenience.

[0003] However, existing 2U server chassis have the following drawbacks in terms of hard drive compartment structure: Currently, most 2U server chassis on the market use a fixed-size hard drive bay design, meaning that each hard drive bay can only install either a 2.5-inch or a 3.5-inch hard drive. If both sizes of hard drives need to be deployed simultaneously, separate bays for each size must be created within the chassis. This design fragments the internal space of the chassis, and the number of hard drives that can be installed is limited by the bay size plan, making it impossible to flexibly respond to dynamic changes in storage needs. On the other hand, as the unit capacity density of hard drives continues to increase, the heat dissipation problem of high-density hard drive bays is becoming increasingly prominent. Traditional high-density bays mostly rely on a single airflow channel with a front intake fan and a rear exhaust fan, which can easily create dead zones between adjacent hard drives, resulting in poor heat dissipation for the middle hard drives. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-bay 2U storage server chassis with an optimized compartmentalized structure, which effectively solves the compatibility problem of mixing hard drives of different sizes, while improving heat dissipation performance under high-density deployment.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a multi-bay 2U storage server chassis with optimized compartment structure, including a chassis body, a panel bolted to the front side of the chassis body, a hard disk storage compartment provided at the front end inside the chassis body, an intake fan assembly provided at the rear side of the hard disk storage compartment, and the intake fan assembly is arranged laterally along the width direction of the chassis body for cooperative use, and the front side of the hard disk storage compartment extends into the interior of the panel; The hard drive storage bay includes a back panel, which is bolted to the inside of the chassis body. A bay frame is bolted to the front of the back panel. The bay frame has several hard drive compartments inside, and each hard drive compartment has several hard drive trays inside. The front end of each hard drive tray is inside the panel, and the hard drive tray has a hard drive mixing mechanism inside.

[0006] By adopting the above technical solution, the fixed top support structure and wedge-shaped fixing structure in the hard drive mixing mechanism enable arbitrary combination and installation of 2.5-inch and 3.5-inch hard drives in the same compartment without the need for a separate dedicated area. This improves the utilization rate of the internal space of the chassis and allows for dynamic adjustment of hard drive configuration according to storage needs, flexibly responding to mixed deployment scenarios with different capacities and performance. The compartment frame adopts a synergistic heat dissipation structure of liquid cooling with copper cold plates and directional air cooling. The internal cooling channels of the copper cold plates directly contact the heat source of the hard drives, and the directional airflow formed by the partition plate air vents and V-shaped air guide plates eliminates the airflow dead zones of traditional single airflow channels. This improves the uniformity of hard drive operating temperature and avoids performance degradation caused by heat accumulation in the middle hard drives, making it suitable for long-term stable operation of high-density storage.

[0007] The present invention is further configured such that: the housing frame includes an installation frame, a copper cold plate is bolted to the interior of the installation frame, a plurality of partition plates are bolted to the top and bottom of the copper cold plate, a hard disk mounting cavity is formed between adjacent partition plates and the installation frame, an air inlet channel is formed between opposite sides of two adjacent partition plates, and an air guide plate is welded between two adjacent partition plates, a plurality of air guide ports are provided inside the partition plates along the length direction, a plurality of cooling channels are provided inside the copper cold plate along the length direction, and a connecting channel is provided at both ends inside the copper cold plate, the connecting channel being connected to the cooling channel.

[0008] By adopting the above technical solution, a bay frame is set up, which forms multiple independent hard drive mounting cavities with mounting frames, copper cold plates, and partitions. This facilitates the installation of multiple hard drives to meet different storage needs. The air intake channels between adjacent partitions work in conjunction with the air guide plates to direct the airflow of the intake fan group to the gaps between the hard drives. The air guides on the partitions further disperse the airflow, ensuring sufficient airflow on the surface of each hard drive. At the same time, the cooling channels inside the copper cold plates are connected through connecting channels and external circulating cooling equipment to form a closed liquid cooling loop. This directly absorbs the heat transferred from the hard drives and acts directly on the high-heat areas of the hard drives (such as the main control chip), compensating for the insufficient heat dissipation of air cooling in high-density scenarios. Furthermore, the cooperation between the air guides and the air intake channels ensures that the airflow is evenly distributed on the surface of each hard drive, eliminating the problem of heat accumulation in the middle of traditional bays.

[0009] The invention is further configured such that: two adjacent air guide plates are arranged in a V-shape, and an air guide channel is formed between the two air guide plates, and several cooling channels are arranged in parallel along the length of the copper cold plate.

[0010] By adopting the above technical solution, the airflow speed between hard drives is increased by the acceleration effect of the V-shaped air guide plate, which enhances the convective heat dissipation efficiency, especially for the outer area of ​​high-density hard drives. The parallel cooling channels ensure that the temperature of each area of ​​the copper cold plate is uniform, avoiding local overheating, adapting to the heat dissipation needs of hard drives in different positions, and improving the overall heat dissipation stability.

[0011] The present invention is further configured such that: the hard disk mixing mechanism includes two fixed plates, the fixed plates are bolted to both sides inside the hard disk tray, a top support assembly is inserted between the opposite sides of the two fixed plates, a plug rod is slidably arranged inside the fixed plate, a movable plate is bolted to the side of the plug rod near the inner wall of the hard disk tray, and a positioning spring is provided between the movable plate and the inner wall of the hard disk tray, a driven wedge block is welded to the opposite side of the top and bottom movable plates, and an active wedge block is in contact with the inner side of the driven wedge block, the active wedge block and the driven wedge block are used in cooperation, and a fixed block is slidably in contact with the side of the active wedge block away from the movable plate.

[0012] By adopting the above technical solution and setting up a hard drive mixing mechanism, the fixing plates on both sides of the hard drive tray support the bottom of the top 2.5-inch hard drive through the top support assembly, enhancing the stability of the top hard drive installation. When installing hard drives of different sizes, the 3.5-inch hard drive is placed at the bottom of the top support assembly. When installing the 2.5-inch hard drive, the top active wedge block is pushed, and its inclined surface presses against the driven wedge block, causing the moving plate to compress the positioning spring, causing the two side insertion rods to retract into the fixing plate. After the 2.5-inch hard drive is inserted, the active wedge block is released, the positioning spring returns to its original position, and pushes the moving plate, causing the insertion rod to extend and penetrate into the standard mounting hole on the side of the hard drive, thus completing the fixing of the top hard drive. The fixing method for the bottom 3.5-inch hard drive corresponds to the fixing structure at the bottom. The wedge block transmission structure realizes the synchronous extension and retraction of the insertion rod, ensuring that the force on both sides of the hard drive is even, avoiding poor interface contact caused by installation misalignment. In addition, the positioning spring provides continuous clamping force, adapting to the thickness difference between 2.5-inch and 3.5-inch hard drives. Mixed installation can be completed without replacing the fixing parts. At the same time, the overall structure has a screwless design, realizing tool-free quick installation and removal of hard drives, reducing maintenance difficulty.

[0013] The present invention is further configured such that: the fixed block is bolted to the side of the fixed plate near the fixed plate, and the active wedge block is slidably connected to the fixed block through a slider, and a push rod is bolted to the rear side of the active wedge block.

[0014] By adopting the above technical solution, the sliding cooperation between the slider and the fixed block ensures the stability of the active wedge block's movement trajectory, avoiding transmission failure caused by deviation. The design of the push rod facilitates operation and improves the convenience of hard drive replacement.

[0015] The invention is further configured such that: the insertion rod includes a hollow rod body, a sleeve is slidably fitted on the surface of the hollow rod body, a sliding rod is bolted inside the hollow rod body, and a sliding sleeve is slidably fitted on the surface of the sliding rod, a plurality of elastic cards are annularly welded on the surface of the hollow rod body away from the fixed plate, a pull rod is annularly welded on the surface of the sliding sleeve, and the other end of the pull rod is connected to the elastic cards, a connecting rod is provided on the inner side of the sleeve, and the other end of the connecting rod extends into the interior of the hollow rod body and is connected to the sliding sleeve.

[0016] Using the above technical solution, by setting up a plug rod, the hollow rod body is inserted into the standard mounting holes on both sides of the hard drive under the elastic action of the positioning spring. When the elastic clip contacts the inner wall of the mounting hole, it retracts under its own elastic force. After the hollow rod body is fully inserted, the elastic clip clamps the inner wall of the mounting hole under its elastic action, completing precise fixation. When it is necessary to release the fixation, the sleeve slides on the surface of the hollow rod body, and the sleeve drives the sliding sleeve to slide on the surface of the sliding rod through the connecting rod. The connecting rod drives the elastic clip to retract, which can release the clamping between the hollow rod body and the inner wall of the mounting hole, realizing the fixation of the hollow rod body to the hard drive.

[0017] The present invention is further configured such that: the top support assembly includes an upper support plate and a lower pressure plate, the upper support plate is inserted between two fixed plates, a connecting block is welded to the bottom of the upper support plate, and a movable block is slidably arranged inside the connecting block, the bottom of the movable block is welded to the lower pressure plate, and a plurality of compression springs are provided between the movable block and the inner wall of the connecting block, and a plurality of copper heat-conducting sheets are welded along the length direction on the opposite side of the upper support plate and the lower pressure plate.

[0018] By adopting the above technical solution, the upper support plate and the lower pressure plate are connected by a connecting block and a movable block. The pressure spring pushes the lower pressure plate to contact the bottom hard drive, while the upper support plate pushes the bottom of the top hard drive upwards, which can support the top hard drive and improve the installation stability of the top hard drive. In addition, the copper heat-conducting plates on the upper support plate and the lower pressure plate are directly attached to the surface of the hard drive, which can conduct and dissipate heat. Combined with liquid cooling and air cooling, the heat is carried away, forming a multi-level heat dissipation path.

[0019] The present invention is further configured such that: the top of the upper support plate and the top of the inner wall of the hard disk tray are provided with receiving grooves, and the receiving grooves are provided with a plurality of heat conduction holes.

[0020] By adopting the above technical solution, the installation slot facilitates the positioning of the hard drive and ensures the connection between the hard drive and the backplane. The internal heat conduction holes form a vertical heat dissipation channel, which can directly conduct the heat of the hard drive to the airflow path, improving the efficiency of passive heat dissipation, especially for the core heat-generating area of ​​the hard drive.

[0021] The present invention is further configured such that: both sides of the upper support plate are welded with plug-in blocks, and each of the two fixing plates has a plug-in groove on one side opposite to the other. The plug-in blocks are located inside the plug-in grooves, and the top and bottom of the plug-in blocks are welded with arc-shaped elastic sheets, and the other side of the elastic sheets is in close contact with the inner wall of the plug-in groove.

[0022] By adopting the above technical solution, the tool-free installation and removal of the top support assembly is achieved through the cooperation of the plug block and the elastic plate. This makes it convenient to install or not install the top support assembly according to the hard drive installation requirements. The elasticity of the arc-shaped elastic plate can provide continuous pre-tightening force to prevent the top support assembly from loosening due to vibration and ensure the stability of heat dissipation contact.

[0023] The present invention is further configured such that: the bottom and top of the backplate corresponding to the hard drive bay are integrated with SATA and PCIe interface slots, and the interface slots adopt the pin type.

[0024] By adopting the above technical solution, the pin-type interface on the back panel reduces cable tangling, optimizes the internal space of the compartment, and reduces the risk of signal loss caused by cable aging. The multi-interface integrated design supports the mixed insertion of different types of hard drives (such as SATA HDD and PCIe NVMe SSD), and in conjunction with the hard drive mixing mechanism, it further improves the flexibility of storage configuration.

[0025] Compared with existing technologies, the present invention provides a multi-bay 2U storage server chassis with an optimized compartmentalized structure, which has the following advantages: This multi-bay 2U storage server chassis with optimized compartment structure allows for arbitrary combination installation of 2.5-inch and 3.5-inch hard drives within the same compartment through a fixed top support structure and wedge-shaped fixing structure in the hard drive mixing mechanism. This eliminates the need for separate dedicated areas, improving the utilization of the chassis's internal space. Hard drive configuration can be dynamically adjusted according to storage needs, flexibly addressing mixed deployment scenarios with different capacities and performance levels. The chassis frame employs a synergistic heat dissipation structure of liquid cooling with copper cold plates and directional air cooling. The copper cold plates' built-in cooling channels directly contact the hard drive heat sources, and the directional airflow formed by the partition plate air vents and V-shaped air guides eliminates airflow dead zones inherent in traditional single-channel systems. This improves the uniformity of hard drive operating temperatures, preventing performance degradation caused by heat accumulation in the central hard drives, and ensuring long-term stable operation for high-density storage.

[0028] 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.

[0029] Please see Figures 1-7 A multi-bay 2U storage server chassis with optimized compartment structure includes a chassis body 1, a panel 2 bolted to the front of the chassis body 1, a hard disk storage compartment 3 located at the front end inside the chassis body 1, an intake fan assembly 9 located at the rear of the hard disk storage compartment 3, and the intake fan assembly 9 being arranged laterally along the width direction of the chassis body 1, with the front of the hard disk storage compartment 3 extending into the interior of the panel 2. The hard drive storage bay 3 includes a backplate 4, which is bolted to the inside of the chassis body 1. A bay frame 5 is bolted to the front of the backplate 4. The bay frame 5 contains several hard drive compartments 6, and each hard drive compartment 6 contains several hard drive trays 7. The front end of each hard drive tray 7 is located inside the panel 2. The hard drive tray 7 contains a hard drive mixing mechanism 8. Through the fixed top support structure and wedge-shaped fixing structure in the hard drive mixing mechanism 8, 2.5-inch and 3.5-inch hard drives can be installed in any combination within the same compartment without the need for a separate dedicated area. The space utilization rate is improved, and the hard drive configuration can be dynamically adjusted according to storage needs to flexibly cope with mixed deployment scenarios with different capacities and performances. The chassis frame 5 adopts a synergistic heat dissipation structure of liquid cooling and directional air cooling with copper cold plate 52. The copper cold plate 52 has built-in cooling channels 57 that directly contact the heat source of the hard drive. Combined with the directional air duct formed by the partition plate 53 air guide vent 56 and V-shaped air guide plate 55, the airflow dead zone of the traditional single air duct is eliminated, which improves the uniformity of hard drive operating temperature and avoids the performance degradation caused by heat accumulation in the middle hard drive, making it suitable for long-term stable operation of high-density storage.

[0030] The hopper frame 5 includes a mounting frame 51. A copper cold plate 52 is bolted to the inside of the mounting frame 51. Several partition plates 53 are bolted to the top and bottom of the copper cold plate 52. Adjacent partition plates 53 and the mounting frame 51 form a hard drive mounting cavity. An air inlet channel 54 is formed between opposite sides of two adjacent partition plates 53. Air guide plates 55 are welded between adjacent partition plates 53. Several air guide ports 56 are formed along the length of the interior of each partition plate 53. Several cooling channels 57 are formed along the length of the interior of the copper cold plate 52. Connecting channels 58 are provided at both ends of the interior of the copper cold plate 52, communicating with the cooling channels 57. By setting up the hopper frame 5, multiple independent hard drive mounting cavities are formed by the mounting frame 51, the copper cold plate 52, and the partition plates 53. The hard drive mounting cavity facilitates the installation of multiple hard drives to meet different storage needs. The air intake channel 54 between adjacent partitions 53 works in conjunction with the air guide plate 55 to direct the airflow of the intake fan group 9 to the gap between the hard drives. The air guide vent 56 on the partition 53 further disperses the airflow, ensuring sufficient airflow on the surface of each hard drive. Meanwhile, the cooling channel 57 inside the copper cold plate 52 is connected to the connecting channel 58, and the connecting channel 58 is connected to an external circulating cooling device to form a closed liquid cooling loop. This directly absorbs the heat transferred from the hard drives and acts directly on the high-heat areas of the hard drives (such as the main control chip), compensating for the insufficient heat dissipation of air cooling in high-density scenarios. Furthermore, the cooperation between the air guide vent 56 and the air intake channel 54 ensures that the airflow is evenly distributed on the surface of each hard drive, eliminating the problem of heat accumulation in the middle of traditional compartments.

[0031] The two adjacent air guide plates 55 are arranged in a V-shape, and an air guide channel is formed between the two air guide plates 55. Several cooling channels 57 are arranged parallel to each other along the length of the copper cold plate 52. The airflow speed between the hard drives is increased by the acceleration effect of the V-shaped air guide plates 55, which enhances the convective heat dissipation efficiency, especially for the outer area of ​​the high-density hard drives. The parallel cooling channels 57 make the temperature of each area of ​​the copper cold plate 52 uniform, avoid local overheating, adapt to the heat dissipation needs of hard drives in different positions, and improve the overall heat dissipation stability.

[0032] The hard drive mixing mechanism 8 includes two fixing plates 81, which are bolted to both sides inside the hard drive tray 7. A top support assembly 82 is inserted between the opposite sides of the two fixing plates 81. A plug rod 83 is slidably arranged inside the fixing plates 81. A movable plate 84 is bolted to the side of the plug rod 83 near the inner wall of the hard drive tray 7, and a positioning spring 85 is provided between the movable plate 84 and the inner wall of the hard drive tray 7. A driven wedge block 86 is welded to the opposite side of the two movable plates 84 at the top and bottom, and an active wedge block 87 contacts the inner side of the driven wedge block 86. The active wedge block 87 works in conjunction with the driven wedge block 86. A fixing block 88 slides in contact with the side of the active wedge block 87 away from the movable plate 84. By setting up the hard drive mixing mechanism 8, the fixing plates 81 on both sides of the hard drive tray 7 support the bottom of the top 2.5-inch hard drive through the top support assembly 82, enhancing the stability of the top hard drive installation. When installing hard drives of different sizes, the 3.5-inch hard drive can be mixed with the 2.5-inch hard drive. The 2.5-inch hard drive is placed at the bottom of the top support assembly 82. When installing a 2.5-inch hard drive, the top active wedge block 87 is pushed, and its inclined surface presses against the driven wedge block 86, causing the moving plate 84 to compress the positioning spring 85. This causes the two side insertion rods 83 to retract into the fixing plate 81. After the 2.5-inch hard drive is inserted, the active wedge block 87 is released, the positioning spring 85 returns to its original position, and pushes the moving plate 84. The insertion rods 83 extend and penetrate into the standard mounting holes on the side of the hard drive, thus securing the top hard drive. The bottom 3.5-inch hard drive is secured using the corresponding bottom fixing structure. The wedge block transmission structure enables the synchronous extension and retraction of the insertion rods 83, ensuring even force on both sides of the hard drive and avoiding poor interface contact caused by installation misalignment. The positioning spring 85 provides continuous clamping force, adapting to the thickness difference between 2.5-inch and 3.5-inch hard drives. Mixed installation can be completed without replacing the fixing parts. At the same time, the overall structure has a screwless design, enabling tool-free quick installation and removal of hard drives and reducing maintenance difficulty.

[0033] The fixed block 88 is bolted to the side of the fixed plate 81, and the active wedge block 87 is slidably connected to the fixed block 88 via a slider. A push rod 10 is bolted to the rear side of the active wedge block 87. The sliding cooperation between the slider and the fixed block 88 ensures the stability of the movement trajectory of the active wedge block 87 and avoids transmission failure caused by deviation. The design of the push rod 10 facilitates operation and improves the convenience of hard drive replacement.

[0034] The insert rod 83 includes a hollow rod body 831, with a sleeve 832 slidably fitted onto the surface of the hollow rod body 831. A sliding rod 833 is bolted inside the hollow rod body 831, and a sliding sleeve 834 is slidably fitted onto the surface of the sliding rod 833. Several elastic clips 835 are annularly welded to the surface of the hollow rod body 831 away from the fixed plate 81. A pull rod 836 is annularly welded to the surface of the sliding sleeve 834, with the other end of the pull rod 836 connected to the elastic clips 835. A connecting rod 837 is provided inside the sleeve 832, with the other end of the connecting rod 837 extending into the interior of the hollow rod body 831 and connecting to the sliding sleeve 834. By providing the insert rod 83, the positioning spring... Under the elastic action of 85, the hollow rod 831 is inserted into the standard mounting holes on both sides of the hard drive. When the elastic card 835 contacts the inner wall of the mounting hole, it contracts under its own elastic force. After the hollow rod 831 is inserted to the outside, the elastic card 835 clamps the inner wall of the mounting hole under the elastic action, completing the precise fixation. When it is necessary to release the fixation, the sleeve 832 slides on the surface of the hollow rod 831, so that the sleeve 832 drives the sliding sleeve 834 to slide on the surface of the sliding rod 833 through the connecting rod 837, and drives the elastic card 835 to contract through the connecting rod 837, which can release the clamping between the hollow rod 831 and the inner wall of the mounting hole, realizing the fixation of the hollow rod 831 to the hard drive.

[0035] The top support assembly 82 includes an upper support plate 821 and a lower pressure plate 822. The upper support plate 821 is inserted between two fixed plates 81. A connecting block 823 is welded to the bottom of the upper support plate 821, and a movable block 824 is slidably disposed inside the connecting block 823. The bottom of the movable block 824 is welded to the lower pressure plate 822. Several compression springs 825 are provided between the movable block 824 and the inner wall of the connecting block 823. Several copper heat-conducting plates 826 are welded along the length of each opposite side of the upper support plate 821 and the lower pressure plate 822. With the top support assembly 82, the upper support plate 821 and the lower pressure plate 822 are connected by the connecting block 823 and the movable block 824. The pressure spring 825 pushes the lower pressure plate 822 to contact the bottom hard drive, while the upper support plate 821 pushes upward to press against the bottom of the top hard drive, which can support the top hard drive and improve the installation stability of the top hard drive. In addition, the copper heat-conducting plates 826 on the upper support plate 821 and the lower pressure plate 822 are directly attached to the surface of the hard drive, which can conduct and dissipate heat. In conjunction with liquid cooling and air cooling, the heat is carried away, forming a multi-level heat dissipation path.

[0036] The top of the upper support plate 821 and the top of the inner wall of the hard drive tray 7 are both provided with receiving slots, and the receiving slots are provided with several heat conduction holes. The receiving slots facilitate the positioning of the hard drive and ensure the connection between the hard drive and the back plate 4. The internal heat conduction holes form a vertical heat dissipation channel, which can directly conduct the heat of the hard drive to the airflow path, improve the passive heat dissipation efficiency, especially for the core heat-generating area of ​​the hard drive.

[0037] The upper support plate 821 has plug-in blocks 11 welded on both sides, and plug-in slots 12 are opened on the opposite side of the two fixing plates 81. The plug-in blocks 11 are located inside the plug-in slots 12, and the top and bottom of the plug-in blocks 11 are welded with arc-shaped elastic pieces 13. The other side of the elastic pieces 13 is in close contact with the inner wall of the plug-in slots 12. The cooperation between the plug-in blocks 11 and the elastic pieces 13 enables tool-free installation and removal of the top support assembly 82, which is convenient for installing or not installing the top support assembly 82 according to the hard drive installation requirements. The elasticity of the arc-shaped elastic pieces 13 can provide continuous pre-tightening force to prevent the top support assembly 82 from loosening due to vibration and ensure the stability of heat dissipation contact.

[0038] The backplate 4 integrates SATA and PCIe interface slots at the bottom and top of the hard drive bay, and the interface slots adopt the pin type. The pin type interface on the backplate 4 reduces cable tangling, optimizes the internal space of the bay, and reduces the risk of signal loss caused by cable aging. The multi-interface integrated design supports the mixed insertion of different types of hard drives (such as SATA HDD and PCIe NVMe SSD), and works with the hard drive mixing mechanism 8 to further improve the flexibility of storage configuration.

[0039] The working principle of this embodiment is as follows: When installing a 3.5-inch hard drive, the operator first pushes the bottom push rod 10, causing the active wedge block 87 to slide along the fixed block 88. The inclined surface of the active wedge block 87 presses against the driven wedge block 86, causing the moving plate 84 to compress the positioning spring 85, which in turn causes the insertion rod 83 to retract into the fixed plate 81. Then, the 3.5-inch hard drive is smoothly placed into the receiving slot in the hard drive tray 7, ensuring that the hard drive interface is aligned with the pin-type interface on the back panel 4. Then, the push rod 10 is released, the positioning spring 85 releases energy, and the moving plate 84 pushes the insertion rod 83 to extend. The elastic clip 835 at the front end of the hollow rod 831 contacts the hard drive mounting plate. The inner wall of the mounting hole undergoes elastic deformation during insertion, returning to its original shape after full insertion, achieving a secure connection. Based on storage requirements, a hard drive configuration plan is devised, determining the installation positions and quantities of 2.5-inch and 3.5-inch hard drives. If a 2.5-inch hard drive needs to be installed, the insertion blocks 11 on both sides of the upper support plate 821 are aligned with the insertion slots 12 on the fixing plate 81 and inserted. The elastic sheet 13 generates frictional resistance against the inner wall of the insertion slot 12, achieving initial fixation. The 2.5-inch hard drive is then placed in the receiving slot within the upper support plate 821, and the above fixing structure steps are repeated to secure the 2.5-inch hard drive. During server operation, the intake fan assembly 9 is activated, and airflow... Air is drawn in from the front of the hard drive storage compartment 3 and blown into the compartment, entering the air intake channel 54 formed by the adjacent partition 53. After being accelerated by the V-shaped air guide plate 55, the airflow is guided along the air guide channel to the gaps between the hard drives. At the same time, the air guide vents 56 on the partition 53 further disperse the airflow, ensuring that each hard drive (including the middle hard drive) has sufficient airflow. After absorbing the heat from the hard drive surface, the airflow flows to the exhaust system at the rear of the chassis, forming a forward-outward directional airflow channel. Simultaneously, the external circulating cooling equipment is activated, and the coolant enters the cooling channel 57 through the connecting channels 58 at both ends of the copper cold plate 52. The parallel cooling channels 57 cover the entire copper cold plate 52. Along its length, the area of ​​the copper cold plate 52 directly contacts the hard drive mounting cavity. The heat generated by the hard drive during operation is transferred to the copper cold plate 52 through the hard drive bracket 7 and the partition plate 53. The coolant absorbs heat when flowing in the cooling channel 57, and then flows back to the cooling equipment through the connecting channel 58 to cool down, forming a closed liquid cooling circuit. Moreover, the copper heat-conducting plate 826 of the top support assembly 82 transfers the core heat of the hard drive (such as the heat of the main control chip) to the upper support plate 821 and the lower pressure plate 822. Some of the heat is diffused into the air-cooled airflow through the heat-conducting holes, and some of the heat is transferred to the copper cold plate 52, realizing multi-level heat dissipation synergy of liquid cooling, air cooling and passive heat conduction.

[0040] Regarding the fixation of the top support assembly 82 through the cooperation of the plug block 11 and the elastic sheet 13, its design has fully considered the reliability under long-term vibration environment: Materials and Structural Design: The instruction manual clearly states that the elastic sheet 13 is arc-shaped. This arc-shaped structure itself provides better elastic deformation space and stress distribution, making it more fatigue-resistant than a straight sheet. The description of tight contact implies that effective pre-stress is generated after installation. This pre-tightened state can significantly resist minor displacements caused by vibration and prevent loosening.

[0041] Vibration Environment Analysis: The vibrations during server operation mainly originate from the fan and the hard drive itself. In this application, the hard drive is rigidly fixed directly to the hard drive tray 7 on both sides via the insertion rod 83. The vibration transmission path of this hard drive is not in the main resonance direction of the vertical support direction of the top support assembly 82. The main function of the top support assembly is to provide upward auxiliary support and heat conduction, and the vibration excitation it experiences is much less than that of the main structure that directly fixes the hard drive.

[0042] Redundancy Design Considerations: Even in the extremely rare event of fatigue loosening of the elastic plate, the hard drive's core is secured by the rigid locking of the side mounting holes by the two side inserts 83, and the bottom of the hard drive is continuously supported upwards by the pressure plate 822 via the compression spring 825. Displacement of the top support assembly will not cause the hard drive to detach or the interface to lose connection; it may only slightly affect the optimal contact pressure of the heat sink 826, and the multi-layer heat dissipation design itself has sufficient margin. Therefore, this design is redundant and reliable in terms of functional safety.

[0043] Regarding the reliability of the anti-displacement mechanism of the insert sleeve: The sleeve 832 of the insert 83 is not without a locking mechanism; its screwless sliding design is precisely for ease of operation, and its anti-displacement reliability is achieved through the following methods: Operating Logic and Force Condition: The sliding of the sleeve 832 requires manual intervention, either by pushing forward or pulling backward, to control the opening and closing of the elastic card 835 through the internal linkage of the connecting rod 837. In the fixed state of the hard drive (i.e., normal operating state), the sleeve 832 is not subjected to any axial driving force that would cause it to slide. The elastic force of the positioning spring 85 is ultimately applied to the hard drive through the moving plate 84 and the hollow rod 831. This force is perpendicular to the sliding direction of the sleeve and will not cause the sleeve to shift.

[0044] Friction-retaining design: The sleeve 832 and the hollow rod 831 have a tight sliding fit, resulting in a certain amount of static friction. In a vibration environment, the energy required for accidental sliding is far greater than the energy that environmental vibration may transmit. Furthermore, the sleeve is typically located on the side of the hard drive, and the main airflow and vibration directions inside the server are not aligned with its axis, further reducing the risk of accidental sliding.

[0045] Structural layout guarantee: The insertion rod mechanism is located on both sides inside the hard drive bracket 7. After the hard drive is installed, the side of the hard drive and the inner wall of the bracket together form a relatively restricted space, which objectively creates a physical constraint on the movement of the sleeve 832, preventing it from coming off due to large vibrations.

[0046] Conventional handling of power cables: The routing and securing of remaining necessary power cables (such as power cables from the power module to the backplane) is a fundamental aspect that any server chassis design must include, and is common knowledge to those skilled in the art. This is typically achieved using cable clips, cable management racks, nylon cable ties, Velcro cable ties, or cable clips on the chassis sidewalls. This design is too common and not an innovative aspect of this invention, therefore it need not be elaborated upon in the patent documents.

[0047] Space Guarantee: This solution, through optimized compartmentation and heat dissipation structure (such as V-shaped air ducts and integrated cooling plates), creates a more orderly and unobstructed space at the rear and top of the hard drive bay. This is actually more conducive to the orderly layout and fixation of power cable bundles than the traditional messy compartmentation.
