Description

Technical Field

[0001] This application relates to the field of immersion liquid-cooled cabinet technology, and in particular to a door structure for use in immersion liquid-cooled cabinets. Background Technology

[0002] As server computing density continues to increase, liquid cooling technology is increasingly being widely used in data centers to improve heat dissipation efficiency and energy efficiency ratio. Among these, immersion liquid-cooled racks, as crucial heat dissipation devices in high-performance computing scenarios, directly impact the rack's mounting density and heat dissipation performance through their internal structural layout and ease of maintenance. In these liquid-cooled racks, to facilitate server insertion, maintenance, and replacement, an opening structure is typically installed at the top of the rack. Common forms include flip-top doors (single flip / double flip type) or sliding doors.

[0003] However, existing flip-door structures flip the entire door upwards when opened. Due to the large length of the flip-door, not only is a large amount of space required at the top of the rack, but if the flip angle is limited to 90°, the large size and thickness of the door itself may obstruct the operator's view or operating path when open, which is not conducive to the placement of servers near the inner end wall or inner side wall of the rack. If the flip-door is designed to have a flip angle greater than 90° in order not to affect the placement of servers near the inner end wall or inner side wall of the rack, the spacing between adjacent racks must be increased appropriately, reducing space utilization.

[0004] Similarly, while sliding door structures can avoid the spatial interference caused by the door flipping upwards, they also require a large lateral space between adjacent cabinets because they need to move a long distance laterally along the upper surface of the cabinet during the sliding opening process.

[0005] Therefore, both single-flip door and sliding door structures in the existing technology have the problem of large door movement range causing interference with space layout, which is not conducive to achieving higher server installation density. Utility Model Content

[0006] To facilitate increasing server installation density, this application provides a door structure for use in immersion liquid-cooled cabinets.

[0007] The door structure for use in immersion liquid-cooled cabinets provided in this application adopts the following technical solution:

[0008] A door structure for use in an immersion liquid-cooled cabinet includes a first flip door and a linear actuator. The first flip door is hinged to the top of the liquid-cooled cabinet, and a second flip door is hinged to the first flip door. The linear actuator is hinged inside the liquid-cooled cabinet and is hinged to the first flip door.

[0009] When the first and second flip doors together close the top opening of the cabinet, the hinge point between the linear actuator and the first flip door is higher than the hinge point between the linear actuator and the cabinet. The hinge point between the linear actuator and the first flip door is closer to the second flip door than the hinge point between the linear actuator and the cabinet. The hinge point between the linear actuator and the cabinet is closer to the second flip door than the hinge point between the first flip door and the cabinet.

[0010] By adopting the above technical solution, the linear actuator drives the first flip door to flip upwards, and the second flip door flips downwards under its own gravity, forming a folding door structure. Furthermore, the flip angle of the first and second flip doors can be greater than 90°, allowing servers within the liquid-cooled rack to be arranged closer to the inner end wall / inner side wall of the rack, thus enabling the rack to accommodate more servers. Additionally, the overall length of the first and second flip doors after opening and folding is less than that of a traditional single-leaf flip door, reducing the spacing between adjacent liquid-cooled racks and further facilitating increased server density.

[0011] Optionally, the first flip door is hinged to the liquid-cooled cabinet via a first hinge joint, the central axis of the rotation axis of the first hinge joint being farther away from the second flip door than the outer side wall of the liquid-cooled cabinet.

[0012] By adopting the above technical solution, it is beneficial to increase the rotation envelope space of the first flip door, which facilitates flipping at a larger angle. It is also beneficial to avoid interference between the door and the server inside the cabinet (especially in application scenarios with a thicker door), and to arrange the server closer to the inner end wall / inner side wall of the liquid-cooled cabinet.

[0013] Optionally, an adjusting block is installed on the inner side wall of the first flip door. The adjusting block has multiple mounting holes. The linear actuator is hinged to a connecting column. The connecting column passes through one of the mounting holes and is fixed to the adjusting block by a nut.

[0014] By adopting the above technical solution, the connection position of the linear actuator can be selected from different mounting holes on the adjustment block, making the length of the force arm when the linear actuator pushes the first tilting door adjustable. Therefore, with a fixed stroke of the linear actuator, different hinge positions between the linear actuator and the first tilting door will cause the first tilting door to tilt at different angles. Thus, during the initial installation stage, appropriate mounting holes can be selected according to actual needs to fine-tune the installation position of the linear actuator, achieving an ideal fit between the linear actuator and the first tilting door, thereby optimizing the tilting effect and movement trajectory.

[0015] In addition, the setting of the adjustment block avoids the need to directly open multiple mounting holes on the first tilting door body, which not only improves the flexibility of installation and adjustment, but also effectively avoids the adverse effects of the multi-hole design on the overall strength and sealing performance of the tilting door, thereby improving the reliability and service life of the structure.

[0016] Optionally, the two ends of the first and second flip doors on opposite sides are hinged by a second hinge joint, and the middle of the first and second flip doors on opposite sides is hinged by a third hinge joint, with the end of the pivot of the third hinge joint located near the second hinge joint on the same side.

[0017] By adopting the above technical solution, a multi-axis hinge structure is formed, which can effectively improve the deformation resistance of the door connection, avoid the shaking or loosening caused by single-point connection during long-term use, and help to achieve more stable synchronous movement when the door is flipped, avoiding problems such as jamming and swaying caused by uneven force.

[0018] Optionally, both the first and second flip doors are provided with observation openings, and a viewing window is bolted to the observation opening. The viewing window is located below the observation opening and its size is larger than the observation opening.

[0019] Optionally, a locking device is also included, which can be used to lock the first and second flip doors onto the liquid-cooled cabinet.

[0020] Optionally, the locking component includes a first snap-fit ​​plate, which is rotatably connected to the bottom of the first flip door and the second flip door. The inner side wall of the liquid cooling cabinet is provided with a first snap-fit ​​groove corresponding to the first snap-fit ​​plate, and the first snap-fit ​​plate is connected to a first lock cylinder.

[0021] By adopting the above technical solution, rotating the first lock cylinder causes the first locking plate to rotate and engage with the corresponding first locking groove, thereby locking the first flip door and the second flip door.

[0022] Optionally, the locking component includes a second lock cylinder, which is installed on the second flip door. The second lock cylinder is connected to two adjusting rods, and the second lock cylinder can control the relative movement of the two adjusting rods. The adjusting rods are connected to connecting rods. The second flip door is equipped with a guide sleeve for the connecting rods to pass through. The end of the connecting rod away from the adjusting rod is connected to a second snap-fit ​​plate. The liquid cooling cabinet has a second snap-fit ​​slot that corresponds one-to-one with the second snap-fit ​​plate.

[0023] By adopting the above technical solution, rotating the second lock cylinder causes the two adjusting rods to move in a relatively distant direction, so that the two connecting rods move away from each other synchronously and drive the second locking plate to insert into the second locking groove, thereby locking the first flip door and the second flip door.

[0024] Optionally, the second snap-fit ​​plate is rotatably connected to a roller, and the connecting rod is provided with a plurality of adjustment holes, the adjustment rod being bolted to the connecting rod through at least one of the adjustment holes.

[0025] By adopting the above technical solution, the design of multiple adjustment holes is conducive to adjusting the relative position of the connecting rod and the adjusting rod, thereby facilitating the adjustment of the relative position of the second locking plate and the second locking groove when the second lock cylinder is rotated into place, which facilitates the early installation and debugging and can adapt to liquid-cooled cabinets of different widths / lengths.

[0026] Optionally, the liquid-cooled cabinet is provided with a connector, the connector having a connector slot, the connector being connected to a snap-fit ​​ball, the snap-fit ​​ball being connected to the connector via a spring, and one side of the snap-fit ​​ball extending into the connector slot. The first flip door is connected to a snap-fit ​​post, the insertion end of the snap-fit ​​post having a guide surface, and the snap-fit ​​post having slots on both sides. When the snap-fit ​​post is fully inserted into the connector slot, the snap-fit ​​ball is inserted into the corresponding slot.

[0027] By adopting the above technical solution, the insertion post is inserted into the slot, and with the help of the elastic locking ball, mechanical final positioning can be achieved, ensuring that the door remains fixed in the predetermined position when closed. The insertion post is designed with a guide arc surface, which, together with the elastic locking ball, helps to generate a slight audible feedback when the door closes, indicating to the user that the door has been properly closed.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. A linear actuator drives the first flip door to flip upwards, while the second flip door flips downwards under its own gravity, forming a folding door structure. Furthermore, the flip angle of both the first and second flip doors can be greater than 90°. This allows servers within the liquid-cooled rack to be arranged closer to the inner end wall / inner side wall of the rack, enabling the rack to accommodate more servers. Additionally, the overall length of the first and second flip doors after opening and folding is less than that of a traditional single-leaf flip door, thus reducing the spacing between adjacent liquid-cooled racks and further increasing server density.

[0030] 2. The design of the adjustment block allows for fine-tuning of the linear actuator's installation position during the initial installation phase by selecting appropriate mounting holes according to actual needs. This ensures an ideal fit between the linear actuator and the first tilting door, thereby optimizing the tilting effect and movement trajectory. Furthermore, it avoids directly creating multiple mounting holes on the first tilting door body, improving installation and adjustment flexibility while effectively preventing adverse effects on the overall strength and sealing performance of the tilting door caused by a multi-hole design, thus enhancing structural reliability and service life.

[0031] 3. The insertion pins into the slots, along with the flexible locking ball, enable mechanical final positioning, ensuring the door remains fixed in the predetermined position when closed. The insertion pins are designed with a guide arc surface, which, together with the flexible locking ball, helps to generate a slight audible feedback when the door closes, indicating to the user that the door has been properly closed.

[0044] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0045] Example 1

[0046] This application discloses a door structure for use in immersion liquid cooling cabinets.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The door structure applied to the immersion liquid-cooled cabinet includes two first flip doors 11 and a locking member 2. Each of the two first flip doors 11 is hinged to one end of the top of the liquid-cooled cabinet via a first hinge joint 13, and the central axis of the rotation shaft of the first hinge joint 13 is farther from the center of the liquid-cooled cabinet than the outer wall of the cabinet. The two first flip doors 11 are arranged opposite each other. A second flip door 12 is hinged to the side of the first flip door 11 away from the first hinge joint 13 via two second hinge joints 14 and a third hinge joint 15. The two second hinge joints 14 are located at one end of the opposite side of the first flip door 11 and the second flip door 12, respectively. The third hinge joint 15 is located in the middle of the opposite side of the first flip door 11 and the second flip door 12, and the end of the rotation shaft of the third hinge joint 15 is located on the same side as the second hinge joint 14. Both the first flip door 11 and the second flip door 12 have observation openings 16, and a viewing window 17 is bolted to the observation opening. The viewing window 17 is located below the observation opening 16 and its size is larger than that of the observation opening 16.

[0048] Locking components 2 are installed at both ends of the first flip door 11 near the second flip door 12 and at both ends of the two second flip doors 12 on opposite sides. The locking components 2 can be used to lock the first flip door 11 and the second flip door 12 onto the liquid cooling cabinet. The locking component 2 includes a first snap-fit ​​plate 21. A first snap-fit ​​plate 21 is rotatably connected to both ends of the first flip door 11 near the second flip door 12 and at both ends of the two second flip doors 12 on opposite sides. The inner side wall of the liquid cooling cabinet has a first snap-fit ​​groove 22 that corresponds one-to-one with the first snap-fit ​​plate 21. The first snap-fit ​​plate 21 is connected to a first lock cylinder 23 for controlling its rotation into the first snap-fit ​​groove 22.

[0049] The first lock cylinder 23 is a conventional lock body. For example, the structure of the first lock cylinder 23 may include a lock shell, a rotating cylinder, and a keyhole. The rotating cylinder is rotatably disposed inside the lock shell, and a driving part is provided on the outer peripheral surface of the rotating cylinder. One end of the first locking plate 21 is connected to the driving part. When the key is inserted and rotated, the rotating cylinder drives the first locking plate 21 to rotate, thereby moving it into or out of the first locking groove 22. The driving part may be an eccentric boss / cam plate / connecting shaft, etc., used to drive the first locking plate 21 to flip when the rotating cylinder rotates.

[0050] like Figure 2 and Figure 5 Four linear actuators 3 are hinged to the side wall of the liquid-cooled cabinet. Each pair of linear actuators 3 forms a group, and each group corresponds one-to-one with the first tilting door 11. The two groups of linear actuators 3 are located at opposite ends of the liquid-cooled cabinet, and the cylinders of the two linear actuators 3 in the same group are hinged to opposite sides of the liquid-cooled cabinet. Adjusting blocks 4 are fixed to the inner side walls of both sides of the first tilting door 11. Each adjusting block 4 has several mounting holes 41 equidistantly spaced along its length. A connecting post 31 is hinged to each linear actuator 3. The connecting post 31 passes through one of the mounting holes 41 and is fixed to the adjusting block 4 with a nut, so that the actuating end of each linear actuator 3 is hinged to the inner side wall of the first tilting door 11 on the same side. The linear actuators 3 can be electric cylinders, pneumatic cylinders, hydraulic cylinders, etc.

[0051] When the first flip door 11 and the second flip door 12 together close the top opening of the liquid-cooled cabinet, the hinge point between the linear actuator 3 and the first flip door 11 is higher than the hinge point between the linear actuator 3 and the liquid-cooled cabinet. The hinge point between the linear actuator 3 and the first flip door 11 is closer to the second flip door 12 than the hinge point between the linear actuator 3 and the liquid-cooled cabinet. The hinge point between the linear actuator 3 and the liquid-cooled cabinet is closer to the second flip door 12 than the hinge point between the first flip door 11 and the liquid-cooled cabinet. The hinge point between the linear actuator 3 and the liquid-cooled cabinet is lower than the hinge point between the first flip door 11 and the liquid-cooled cabinet.

[0052] The implementation principle of this application embodiment is as follows: the linear actuator 3 drives the first flip door 11 to flip upward, and the second flip door 12 flips downward under its own gravity, forming a folding door structure. Furthermore, the flip angle of the first flip door 11 and the second flip door 12 can be greater than 90°, which allows the servers inside the liquid-cooled cabinet to be arranged closer to the inner end wall / inner side wall of the liquid-cooled cabinet, thus allowing for the placement of more servers within the liquid-cooled cabinet. Additionally, after the first flip door 11 and the second flip door 12 are opened and folded in half, their overall length is less than that of a traditional single-leaf flip door structure, thereby reducing the spacing between adjacent liquid-cooled cabinets and further improving server installation density.

[0053] Example 2

[0054] Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that a sealing gasket 18 is provided on the opposite side of the first flip door 11 and the second flip door 12. When the first flip door 11 and the second flip door 12 jointly close the top opening of the liquid cooling cabinet, the sealing gasket 18 of the first flip door 11 and the sealing gasket 18 of the second flip door 12 press against each other.

[0055] Reference Figure 8 , Figure 9 , Figure 10 and Figure 11 The locking component 2 includes two second lock cylinders 24, which are respectively installed on opposite sides of the second flip door 12. Each second lock cylinder 24 is connected to two adjusting rods 25, both located below the second flip door 12. The two adjusting rods 25 are parallel to each other and each located on one side of the second lock cylinder 24. The second lock cylinder 24 can control the relative movement of the two adjusting rods 25. Each adjusting rod 25 is bolted to a connecting rod 27. The connecting rod 27 has several adjusting holes 261 equidistantly spaced along its length. The connecting rod 27 is bolted to the adjusting rod 25 through at least one of the adjusting holes 261. A guide sleeve 28 is installed at the bottom of the second flip door 12 for the connecting rod 27 to pass through. A second locking plate 29 is connected to the end of the connecting rod 27 away from the adjusting rod 25. The second locking plate 29 is L-shaped, and a roller 210 is hinged to the end of the second locking plate 29 away from the adjusting rod 25. The liquid cooling cabinet has second locking slots 211 corresponding to the second locking plates 29. Rotating the second lock cylinder 24 causes the two adjusting rods 25 to move in a relatively distant direction, causing the two connecting rods 27 to move away from each other synchronously and drive the second locking plate 29 to insert into the second locking groove 211, thereby locking the first flip door 11 and the second flip door 12.

[0056] In this embodiment, the second lock cylinder 24 is a conventional lock body. For example, the structure of the second lock cylinder 24 may include a lock shell, a rotating core, and a keyhole. The rotating core is rotatably disposed inside the lock shell, and a driving part is provided on the outer peripheral surface of the rotating core. One end of the second locking plate 29 is connected to the driving part. When the key is inserted and rotated, the rotating core drives the second locking plate 29 to rotate, thereby moving it into or out of the second locking groove 211. The driving part may be an outer ring gear or a double rack structure. The two racks are arranged opposite each other and mesh with the outer ring gear. The two racks are respectively connected to an adjusting rod 25, which is used to drive the two first locking plates 21 to move relative to each other when the rotating core rotates.

[0057] like Figure 6 and Figure 7 The liquid-cooled cabinet has four sockets 5 on both sides of its top. Two sockets 5 form a group, and each group corresponds to one of the first flip doors 11. The two sockets 5 in the same group are located on opposite sides of each first flip door 11. A socket slot 51 is formed on the top of each socket 5. Two locking balls 52 are connected to each socket 5 via springs (not shown in the figure). One side of each locking ball 52 extends into the socket slot 51 from one side of the slot. A locking post 6 is connected to the side of the first flip door 11 adjacent to the second flip door 12. The locking post 6 corresponds to one of the sockets 5. The insertion end of the locking post 6 has a guide surface 61, and locking slots 62 are formed on both sides of the locking post 6. When the locking post 6 is fully inserted into the socket slot 51, the locking ball 52 is inserted into the corresponding slot 62.

[0058] The locking post 6 inserts into the insertion slot 51, and together with the elastic locking ball 52, it can achieve mechanical final positioning, ensuring that the door remains fixed in the predetermined position when closed. The locking post 6 is designed with a guide arc surface, which, together with the elastic locking ball 52, helps to generate a slight audible feedback when the door closes, indicating to the user that the door has been closed correctly.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
