Description

Technical Field

[0001] This invention belongs to the field of server rack technology, specifically relating to a computing server rack. Background Technology

[0002] Currently, with the rapid development of computer technology and the establishment of many large-scale Internet data centers, the concentration of electronic devices is becoming increasingly high. Servers are installed on multiple carrier plates inside the rack, and the carrier plates have ventilation slots to facilitate airflow. When the server is working, it generates heat, thus requiring heat dissipation inside the rack. Since hot air rises, existing rack cooling methods typically have air inlets on the bottom and cooling fans on the top. The cooling fans draw air upwards, accelerating airflow inside the rack. This airflow comes into contact with the server and carries away the heat it generates, thereby achieving heat dissipation. In existing technology, when installing the server on the carrier plate 11, a certain space is left between the server and the rack on both sides to facilitate installation and removal by staff. However, when the air flows upward through the sides of the carrier plate, it cannot directly contact the server, thus reducing the heat dissipation efficiency. Therefore, we provide a computing server rack. Summary of the Invention

[0003] The purpose of this invention is to provide a computing server rack that, after the server is installed on the support plate, automatically drives the circular columns on both sides to rotate toward the center. As air flows upward, it is guided by the through-slots and blown directly toward the side of the server, utilizing the air on both sides of the support plate and improving the heat dissipation efficiency of the server. Meanwhile, the through-slots on the support plate where no server is installed are vertically upward, which does not cause turbulence to the upward airflow and improves ventilation efficiency.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A computing server rack includes a rack body, in which several evenly distributed support plates are arranged. Mounting slide rails are fixed on both sides of the upper end of the support plates. A server is installed between two of the mounting slide rails. Several evenly distributed strip-shaped ventilation slots are processed in the middle of the support plates. Air inlets are processed on the left and right walls of the lower side of the rack body. A cooling fan is installed at the upper end of the rack body. The upper left and right sides of the bearing plate are machined with several arc-shaped grooves, which are respectively located on both sides of the two mounting slide rails. The lower end of the arc-shaped groove is provided with a connecting groove that communicates with the outside. A circular column is rotatably assembled in the arc-shaped groove through a rotating shaft. The circular column is provided with a through groove that extends radially to both sides and passes through vertically. The rotating shaft connected to the circular column and the bearing plate are provided with a rotating assembly. The rotating assembly includes a mounting cavity inside the rear end of the support plate. Several rotating shafts extend into the mounting cavity and are connected to gears at their ends. Sliding rods are slidably mounted on both the left and right sides of the mounting cavity. Each sliding rod has a rack machined on its upper side, corresponding to the several gears. The gears mesh with the corresponding racks. A first spring is provided between the two sliding rods at their opposite ends and the sidewall of the mounting cavity. Two left-right sliding grooves are provided on the upper side of the support plate. Push rods are slidably mounted in each of the two sliding grooves.

A horizontal plate is hinged to the upper end of the two first hinge rods. An inclined plate extending into the space between the two mounting rails is fixed to the horizontal plate.

[0005] A telescopic rod is provided between the horizontal plate and the supporting plate.

[0006] The cabinet is equipped with a smoke detector.

[0007] A rectangular groove running vertically through the middle of the rear end of several of the bearing plates is provided. A cylinder is fixed at the upper end of the cabinet. The output shaft of the cylinder extends into the cabinet and is connected to a strip plate that matches the rectangular groove. The strip plate extends into the interior of several of the rectangular grooves. The mounting cavity is equipped with a sealing assembly that matches the plurality of strip-shaped ventilation slots. The sealing assembly includes a movable plate inside the mounting cavity, the movable plate being fixedly connected to the strip-shaped plate, a push plate being fixed to the front end of the movable plate, a bevel being machined on the left end of the push plate, an mounting groove being provided in the middle of the bearing plate, a sealing plate being slidably assembled in the mounting groove, the sealing plate having an air outlet groove corresponding to each of the plurality of strip-shaped ventilation slots, a second spring being provided between the left end of the sealing plate and the side wall of the mounting groove, a slot communicating with the mounting cavity being provided at the rear end of the mounting groove, a pushing block being fixed to the rear end of the sealing plate, the pushing block extending through the slot into the mounting cavity, a vertical groove matching the push plate being provided in the middle of the pushing block, and the bevel of the push plate abutting against the side wall of the vertical groove.

[0008] The lower sides of both the left and right ends of the movable plate are hinged with second hinge rods. Sliding rods are slidably assembled on both the left and right sides of the mounting cavity. The lower ends of the two second hinge rods are respectively hinged to the two sliding rods. The length of the second hinge rod is greater than the length of the first hinge rod. The other ends of the two sliding rods abut against the two sliding rods respectively.

[0009] Several evenly distributed rotating rods are rotatably mounted inside the two air inlets, and each of the rotating rods is fixed with a sealing plate. A rectangular plate is vertically slidably mounted at the rear end of the air inlet. The rectangular plate has several movable slots corresponding to the sealing plates.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-11 As shown, a computing server 0 rack of the present invention includes a rack body 1, a plurality of evenly distributed support plates 11 are arranged inside the rack body 1, mounting slide rails 111 are fixed on both sides of the upper end of the support plate 11, a server 0 is installed between two mounting slide rails 111, a plurality of evenly distributed strip ventilation slots 12 are processed in the middle of the support plate 11, air inlets 13 are processed on the left and right walls of the lower side of the rack body 1, and a cooling fan 14 is installed at the upper end of the rack body 1. The upper left and right sides of the bearing plate 11 are machined with several arc-shaped grooves 2. The arc-shaped grooves 2 are located on both sides of the two mounting slide rails 111. The lower end of the arc-shaped groove 2 is provided with a connecting groove 21 that communicates with the outside. A circular column 23 is rotatably assembled in the arc-shaped groove 2 through a rotating shaft. The circular column 23 is provided with a through groove 24 that extends radially to both sides and passes through vertically. The rotating shaft connected to the several circular columns 23 and the bearing plate 11 are provided with a rotating assembly. The rotating assembly includes a mounting cavity 3 located inside the rear end of the bearing plate 11. Several rotating shafts extend into the mounting cavity 3 and are connected to gears 31 at their ends. Slide rods 32 are slidably mounted on both the left and right sides of the mounting cavity 31. The upper sides of the two slide rods 32 are machined with racks 33 corresponding to the several gears 31. The gears 31 mesh with the corresponding racks 33. A first spring 34 is provided between the two slide rods 32 and the side wall of the mounting cavity 3 at their ends. The upper side of the bearing plate 11 is provided with two left and right distributed slide grooves 35. Push rods 36 are slidably mounted in the two slide grooves 35. The two push rods 36 extend into the mounting cavity 3 and abut against the ends of the two slide rods 32 respectively. The upper ends of the two push rods 36 are hinged with first hinge rods 37. The upper ends of the two first hinge rods 37 are hinged together with a horizontal plate 38. The horizontal plate 38 is fixed with an inclined plate 39 that extends into the space between the two mounting slide rails 111. When server 0 is installed between two slide rails 111, it can drive the horizontal plate 38 downward by pushing the inclined plate 39.

[0018] When cooling the server 0 installed in the internal cabinet 1, the cooling fan 14 at the top of the cabinet 1 is turned on. The cooling fan 14 draws outside air into the cabinet 1 through the two air inlets 13. The air flows from bottom to top and is finally discharged from the top of the cabinet 1. During the process of the air flowing from bottom to top, it comes into contact with the server 0 body and takes away the heat on its surface, realizing heat exchange, thereby cooling the server 0 body and preventing the server 0 body from overheating and being damaged. When no server 0 is installed between the two mounting slide rails 111, the through slot 24 of the circular column 23 is vertical, and the two push rods 36 are located at one end of the two slide rails 35 respectively. The vertical position of the through slots 24, in conjunction with the several strip ventilation slots 12, can reduce the obstruction of air. That is, the air slots of the support plate 11 without the server 0 are all vertically upward, which accelerates the upward flow of air and thus improves the heat dissipation efficiency. When a server 0 is installed between two mounting rails 111, the server 0 can be slid backward along the two mounting rails 111 and then fixed to ensure that the server 0 is stably installed on the support plate 11. When the server 0 is installed, its rear end slides into the rear end of the mounting rail 111 and can contact the inclined plate 39. Then, by pushing the inclined plate 39, the horizontal plate 38 moves downward. When the sliding plate 38 moves downward, it can push the two push rods 36 away from each other through the two first hinge rods 37. Since the two push rods 36 abut against the ends of the two slide rods 32 respectively, when the two push rods 36 move away from each other, they can push the two slide rods 32 away from each other. The rack 33 on the slide rod 32 meshes with the gear 31, which can drive the circular column 23 in the arc groove 2 to rotate through the rotating shaft, so that the circular columns on both sides can rotate. All the cylindrical columns 23 rotate towards the center, with a rotation angle between 30 and 60 degrees. This allows the through-slots 24 of the cylindrical columns 23 to face the side of the server 0. When air flows upward from both sides of the support plate 11, it is guided by the through-slots 24 and blown directly towards the side of the server 0, utilizing the air on both sides of the support plate 11 and improving the heat dissipation efficiency of the server 0. The server 0 is mounted on the support plate 11 via mounting rails 111, meaning there is a certain distance between the bottom of the server 0 and the support plate 11. Therefore, as air flows upward, the air in the center is directly blown towards the bottom of the server 0 through several strip ventilation slots 12, dissipating heat from the bottom of the server 0 and improving the heat dissipation effect. After the server 0 is removed from the two mounting rails 111, it can be reset by pushing the slide rod 32 with the first spring 34, which in turn drives the inclined plate 39 to reset. After the server is installed on the support plate, the present invention can automatically drive the circular columns on both sides to rotate toward the center. When the air flows upward, it will be guided by the through slots and blow directly toward the side of the server, making use of the air on both sides of the support plate and improving the heat dissipation efficiency of the server. The through slots on the support plate where no server is installed are vertically upward, so they will not cause turbulence to the upward airflow and improve ventilation efficiency.

[0019] A telescopic rod 381 is provided between the horizontal plate 38 and the bearing plate 11; in this way, the horizontal plate 38 can only move up and down by extending and retracting the telescopic rod 281.

[0020] Cabinet 1 is equipped with a smoke detector; when a fire occurs inside cabinet 1, the smoke detector will detect the smoke and sound an alarm to alert staff that a fire has occurred in cabinet 1 and to take timely action.

[0021] A rectangular groove 4 that runs vertically through the middle of the rear end of several bearing plates 11 is provided. A cylinder 41 is fixed at the upper end of the cabinet 1. The output shaft of the cylinder 41 extends into the cabinet 1 and is connected to a strip plate 42 that matches the rectangular groove 4. The strip plate 42 extends into the rectangular groove 4. The mounting cavity 3 is equipped with a sealing assembly that matches several strip ventilation slots 12. The sealing assembly includes a movable plate 5 inside the mounting cavity 3. The movable plate 5 is fixedly connected to the strip plate 42. A push plate 51 is fixed at the front end of the movable plate 5. The left end of the push plate 51 is machined with a bevel. An mounting groove 52 is provided in the middle of the bearing plate 11. A sealing plate 53 is slidably assembled in the mounting groove 52. The sealing plate 53 is provided with an air outlet groove 531 that corresponds one-to-one with several strip ventilation slots 12. A second spring 54 is provided between the left end of the sealing plate 53 and the side wall of the mounting groove 52. The rear end of the mounting groove 52 is provided with a slot that communicates with the mounting cavity 3. A push block 55 is fixed at the rear end of the sealing plate 53. The push block 55 extends into the mounting cavity 3 through the slot. A vertical groove 56 that matches the push plate 51 is provided in the middle of the push block 55. The bevel of the push plate 51 abuts against the side wall of the vertical groove 56. The lower sides of both ends of the movable plate 5 are hinged with second hinge rods 6. Sliding rods 61 are slidably assembled on both sides of the mounting cavity 3. The lower ends of the two second hinge rods 6 are respectively hinged to the two sliding rods 61. The length of the second hinge rods 6 is greater than the length of the first hinge rod 37. The other ends of the two sliding rods 61 abut against the two sliding rods 32 respectively. Several evenly distributed rotating rods 7 are rotatably mounted inside the two air inlets 13. Each rotating rod 7 is fixed with a sealing plate 71. A rectangular plate 72 is vertically slidably mounted at the rear end of the air inlet 13. The rectangular plate 72 has several movable slots 73 corresponding to the sealing plates 71. A guide rod 74 extending into the movable slot 73 is fixed at the rear end of the sealing plate 71. Two connecting plates 75 are fixedly connected to the lower end of the strip plate 42. The two connecting plates 75 are respectively connected to the upper ends of the two rectangular plates 72. In the initial state, the sealing plates 71 inside the air inlet 13 are all in a horizontal state to ensure normal air intake; under the elastic force of the second spring 54, the air outlet grooves 531 on the sealing plate 53 are aligned with the strip ventilation grooves 12 to ensure normal air flow. When a fire occurs inside cabinet 1, the smoke alarm will sound to alert the staff. At the same time, the cooling fan 12 at the top of cabinet 1 will stop working, and the cylinder 41 at the top of cabinet 1 will work, driving the strip plate 42 to move downward. When the strip plate 42 moves downward, it can drive the sealing plate 53 to move to the left, so that several air outlet slots 531 and several strip ventilation slots 12 are staggered. It can also drive the circular column 23 to continue to rotate, so that its through slot 24 abuts against the side wall of the arc slot 2. The side wall of the circular column 23 will block the connecting slot 21, thereby achieving a seal. At the same time, it can drive the rectangular plate 72 to move downward, so that several sealing plates 71 rotate downward. The sealing plates 71 abut against each other, blocking the air inlet 13. In this way, when a fire occurs inside the cabinet 1, the air inlet 13 is blocked to prevent the inside of the cabinet 1 from communicating with the outside air and to prevent the fire from spreading. At the same time, the air ducts on the support plate 11 are blocked to form a sealed space between each support plate 11. When one of the servers 0 catches fire, it can prevent the fire from spreading to other servers 0 and causing unnecessary economic losses. Specifically, the downward movement of the strip plate 42 can drive the moving plate 5 inside the mounting cavity 3 to move downward, causing the push plate 51 located in the vertical groove 56 to move downward. Since the left end of the push plate 51 is machined with a bevel and abuts against the side wall of the vertical groove 56, when the push plate 51 moves downward, it can push the push block 55 to move to the left, thereby driving the sealing plate 53 slidably assembled in the mounting groove 52 to move to the left, so that the several air outlet grooves 531 on the sealing plate 53 are staggered from the strip ventilation grooves 12, which can block the several strip ventilation grooves 12 on the bearing plate 11. Specifically, the circular column 23 of the support plate 11 on which the server 0 is installed has rotated towards the center. The push rod 36 has moved to the end of the slide groove 35 and can no longer push the slide rod 32. That is, at this time, the sliding rod 61 inside the mounting cavity 3 is not in contact with the slide rod 32. When the strip plate 42 moves downward and drives the moving plate 5 inside the mounting cavity 3 to move downward, it will drive the sliding rod 61 to move towards the slide rod 32 through the second hinge rod 6. Since the length of the second hinge rod 6 is greater than the length of the first hinge rod 37, when the moving plate 5 moves downward... The movement can push the sliding rod 61 a longer distance through the second hinge rod 6. That is, after the sliding rod 61 moves towards the sliding rod 32 and abuts against it, it will continue to push the sliding rod 32 to move. Through the meshing of the rack 33 and the gear 31, the circular rod 23 will continue to rotate until the circular rod 23 rotates 90 degrees compared with the initial position. This will make the through groove 24 inside the circular rod 23 horizontal, and its two ends will abut against the side wall of the arc groove 2. The lower end of the circular rod 23 will block the connecting groove 21, thereby sealing it. Specifically, the downward movement of the strip plate 42 will drive the rectangular plate 72 to move downward through the connecting plate 75. Since one end of the sealing plate 71 rotates through the rotating rod 7 and the other end extends into the movable groove 73 of the rectangular plate 72 through the guide rod 74, the movable groove 73 provides the movement stroke for the guide rod 74. Therefore, when the rectangular plate 72 moves downward, it can drive the sealing plate 71 to flip downward around the rotating rod 7 as the center, so that several sealing plates 71 will abut against each other and block the air inlet 13.

[0022] Rubber pads are provided on both the upper and lower sides of several sealing plates 71; by providing rubber pads on both sides of several sealing plates 71, the sealing effect can be improved when several sealing plates 71 abut against each other.

[0023] Both air inlets 13 are detachably connected to dust covers on their outer sides; in this way, the air entering the cabinet 1 can be filtered through the dust covers to prevent external impurities from entering the cabinet 1.

[0024] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
