Description

Technical Field

[0001] The present application relates to the technical field of data center equipment, and in particular to a UPS cabinet. Background Art

[0002] USP cabinets are specially designed for storing and managing IT equipment. They are usually used in data centers, server rooms, and other places where a large number of IT equipment needs to be centrally managed. The USP cabinets have an integrated uninterruptible power supply system to ensure stable power supply during power outages and protect the security of data and equipment. USP cabinets have become indispensable equipment in modern data centers and server rooms due to their flexibility, high-density storage capacity, effective power management, security, and intelligent management functions.

[0003] The power module integrated inside the UPS cabinet will generate a lot of heat when working. If this heat accumulates in the cabinet, it will cause the internal temperature to rise. Excessive temperature will cause the UPS system to not work properly, so it is generally necessary to dissipate heat inside the cabinet. The conventional way to enhance heat dissipation is usually to increase the number of fans, but increasing the number of fans will expand the space occupied inside the cabinet, which will not only affect the placement of other components inside the cabinet, but also will not significantly improve the heat dissipation effect of the cabinet. Summary of the invention

[0004] In order to improve the situation where adding a fan not only affects the placement of other components inside the cabinet but also does not significantly improve the heat dissipation effect of the cabinet, the present application provides a UPS cabinet.

[0005] The present application provides a UPS cabinet, which adopts the following technical solution: A UPS cabinet, comprising: A cabinet body, wherein a porous plate is arranged in the cabinet body, wherein a plurality of through holes are formed through the porous plate, and the space in the cabinet body is divided into a module storage area and an active heat dissipation area, wherein the module storage area is used to place a power module; The cabinet is provided with a partition plate in the active heat dissipation area, and the partition plate divides the active heat dissipation area into a mutually independent air extraction area and an exhaust area, and the air extraction area is located below the exhaust area, and the cabinet is provided with an air inlet at the bottom corresponding to the air extraction area, and an air outlet at the top corresponding to the exhaust area; The cabinet is horizontally slidably connected to an exhaust plate in the exhaust area, and the cabinet is horizontally slidably connected to an exhaust plate in the exhaust area. The exhaust plate and the exhaust plate are both placed vertically and move in opposite directions. A driving component for driving the exhaust plate and the exhaust plate to move is also provided in the cabinet.

[0006] By adopting the above technical solution, the cabinet is provided with an air inlet at the bottom and an air outlet at the top. By utilizing the thermal chimney effect, cold air can enter the cabinet from the bottom air inlet, dissipate the heat to the power module through the perforated porous plate, and finally the cooled hot air is discharged from the top air outlet to complete the air flow circulation. The cabinet is also provided with an air extraction plate and an exhaust plate with opposite movement directions. When the air extraction plate moves away from the module storage area, the space between the air extraction plate and the porous plate gradually increases, so that the external cold air can be actively drawn into the cabinet, thereby speeding up the speed of cold air entering. When the air extraction plate moves away from the module storage area, the exhaust The plate moves toward the direction approaching the porous plate, so that the space between the exhaust plate and the porous plate is gradually reduced, thereby actively discharging hot air from the air outlet, accelerating the rate of hot air discharge. When the air extraction plate moves toward the direction approaching the porous plate, the exhaust plate moves away from the porous plate. At this time, the air extraction plate actively pushes the cold air from bottom to top into the module placement area, accelerating the speed of cold air movement. At the same time, the exhaust plate actively draws the cold air from the lower layer of the module placement area to the upper layer, further accelerating the air flow circulation. The reciprocating motion of the air extraction plate and the exhaust plate in the cabinet can effectively promote the intake of cold air and the discharge of hot air, thereby effectively improving the heat dissipation effect of the cabinet without adding a fan.

[0007] Optionally, the driving assembly includes a driving rack, a driven rack and a linkage gear, the driving rack is horizontally arranged at the lower part of the exhaust plate, the driven rack is horizontally arranged at the upper part of the suction plate, and the linkage gear is rotatably connected between the driving rack and the driven rack, and is meshed with the driving rack and the driven rack at the same time.

[0008] By adopting the above technical solution, the driving rack drives the driven rack to move in the opposite direction through the linkage gear, thereby realizing the reverse movement of the air extraction plate and the exhaust plate.

[0009] Optionally, the driving assembly also includes a cam, which is rotatably connected to a side of the exhaust plate away from the module storage area and is parallel to the rotation axis of the linkage gear. The axis of the cam corresponds to the horizontal height of the driving rack, and the side wall of the cam is in sliding contact with one end of the driving rack. A reset elastic member is provided at the end of the driving rack away from the cam, and the reset elastic member is used to restore the position of the driving rack.

[0010] By adopting the above technical solution, the side wall of the cam slides in contact with the driving rack during rotation, thereby causing the driving rack to reciprocate in the horizontal direction. The driving rack compresses the reset elastic part when it moves close to the porous plate. At this time, the reset elastic part is deformed under pressure and stores elastic potential energy. The elastic potential energy stored in the reset elastic part can drive the driving rack to reset, thereby allowing the driving rack to reciprocate in the horizontal direction.

[0011] Optionally, the cabinet is provided with a horizontal isolation plate at a position corresponding to the partition plate in the module placement area, and the isolation plate is provided with ventilation holes in the vertical direction. A stop plate is horizontally slidably connected inside the isolation plate, and the stop plate can open or close the ventilation holes during the sliding process. The driving rack is connected to the stop plate through a connecting rod to drive the stop plate to move synchronously with the driving rack.

[0012] By adopting the above technical solution, the cut-off plate can move synchronously with the driving rack, that is, the cut-off plate can move synchronously with the exhaust plate. When the exhaust plate moves toward the porous plate, the cut-off plate follows the movement and cuts off the ventilation holes, so that the module storage area is divided into two parts separated by an upper and a lower part. Since the cut-off plate cuts off the ventilation holes, the hot air will not move downward, so that the exhaust plate can completely discharge the hot air on the upper layer out of the cabinet, avoiding the hot air from moving downward and prolonging the time it stays inside the cabinet.

[0013] Optionally, the cabinet is provided with multiple layers of placement boards in the vertical direction in the module storage area, and a liquid cooling module is provided in each layer of the placement boards. The liquid cooling module is used to be placed close to the power module to perform liquid cooling on the power module, and a liquid cooling pipe is passed through the liquid cooling module.

[0014] By adopting the above technical solution, when air cooling is not enough to reduce the temperature of the power module, the liquid cooling module is started. Since the power module is in close contact with the liquid cooling module, the liquid cooling module can take away the high temperature on the surface of the power module, thereby further reducing the temperature inside the cabinet.

[0015] Optionally, a liquid cooling circulation box is provided on the top of the cabinet, and independent liquid cooling main inlet pipes and liquid cooling main outlet pipes are respectively provided on both sides of the corresponding liquid cooling modules in the module storage area. The liquid cooling main inlet pipe and the liquid cooling main outlet pipe are both connected to the liquid cooling circulation box, and the inlet end of the liquid cooling pipe in each liquid cooling module is connected to the liquid cooling main inlet pipe, and at the same time, the outlet end of the liquid cooling pipe in each liquid cooling module is connected to the liquid cooling main outlet pipe, and the liquid cooling pipe corresponding to each liquid cooling module is provided with an isolation valve at the inlet end.

[0016] By adopting the above technical solution, each liquid cooling module has an independent liquid cooling pipe to connect the refrigerant, and when some liquid cooling modules are not placed with power modules, the corresponding liquid cooling modules can be shielded by isolation valves, thereby reducing the power consumption of the equipment.

[0017] Optionally, the cabinet is provided with dustproof nets at the air inlet and the air outlet.

[0018] By adopting the above technical solution, dustproof nets are provided at the air inlet and the air outlet of the cabinet, and the dustproof nets can block foreign matter such as dust outside the cabinet, reducing the impact of foreign matter on the internal components of the cabinet.

[0019] Optionally, the cabinet is provided with an air inlet fan at the air inlet, and an air outlet fan at the air outlet.

[0020] By adopting the above technical solution, the cabinet is provided with an air inlet fan at the air inlet, and an air outlet fan at the air outlet, which can further improve the efficiency of cold air intake and hot air discharge.

[0021] Optionally, universal wheels are provided at the bottom of the cabinet.

[0022] By adopting the above technical solution, universal wheels are provided at the bottom of the cabinet, so that the cabinet can be moved to any position, making it convenient for staff to arrange the cabinet.

[0023] In summary, the present application includes at least one of the following beneficial effects: 1. By using the exhaust plate and the exhaust plate to move synchronously and in opposite directions, the intake of cold air can be actively accelerated, and the discharge of hot air can be actively accelerated, effectively improving the heat dissipation effect of the cabinet without increasing the number of fans; 2. By adopting the synchronous movement of the cut-off plate and the driving rack, the cut-off plate can cut off the ventilation holes while the exhaust plate moves toward the porous plate, so that the hot air can be completely discharged from the cabinet, reducing the time the hot air stays in the cabinet; 3. By adding a liquid cooling module in the cabinet, when the air cooling effect of the cabinet is insufficient, liquid cooling can be enabled simultaneously to further improve the cooling effect of the cabinet.

[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] The present application embodiment discloses a UPS cabinet, referring to Figure 1 The UPS cabinet includes a cabinet body 1, a vertically placed porous plate 2 is fixed in the cabinet body 1, and a plurality of through holes are provided on the porous plate 2 at intervals and through the porous plate 2. The porous plate 2 divides the space in the cabinet body 1 into a module storage area 11 and an active heat dissipation area 12. The two cavities of the module storage area 11 and the active heat dissipation area 12 are connected through the through holes on the porous plate 2. A plurality of power modules 111 are placed in layers along the vertical direction in the module storage area 11, and an active heat dissipation structure for dissipating heat from the power modules 111 is provided in the active heat dissipation area 12.

[0028] The cabinet 1 is fixed with a horizontally placed partition plate 13 in the active heat dissipation area 12, and the partition plate 13 divides the active heat dissipation area 12 into an independent air extraction area 121 and an air exhaust area 122, and the air extraction area 121 is located below the air exhaust area 122. The cabinet 1 is provided with an air inlet 14 on the bottom side wall corresponding to the air extraction area 121, and an air inlet fan 141 is fixed at the air inlet 14 of the cabinet 1. At the same time, the cabinet 1 is provided with an air outlet 15 on the top cabinet 1 corresponding to the exhaust area 122, and an air outlet fan 151 is fixed at the air outlet 15, and the air outlet 15 is provided on the side wall and the top wall of the cabinet 1. The cabinet 1 is fixed with dust screens at both the air inlet 14 and the air outlet 15, and the dust screens are fixed to the outside of each fan.

[0029] The cabinet 1 is provided with an air inlet 14 at the bottom and an air outlet 15 at the top. By utilizing the thermal chimney effect, cold air can enter the cabinet 1 from the bottom air inlet 14, dissipate heat from the power module 111 through the perforated porous plate 2, and finally the hot air after cooling is discharged from the top air outlet 15 to complete the air flow cycle. The fans provided at the air inlet 14 and the air outlet 15 can further improve the efficiency of cold air intake and hot air discharge. At the same time, the dustproof net can block foreign matter such as dust outside the cabinet, reducing the impact of foreign matter on the internal components of the cabinet. In addition, universal wheels are fixed at the bottom of the cabinet 1, so that the cabinet can be moved to any position, which is convenient for the staff to arrange the cabinet.

[0030] Reference Figure 2 and Figure 3 The cabinet 1 is horizontally slidably connected with an air extraction plate 16 in the air extraction area 121, and the cabinet 1 is horizontally slidably connected with an exhaust plate 17 in the exhaust area 122. The air extraction plate 16 and the exhaust plate 17 are both placed vertically and move in opposite directions. The side walls of the air extraction plate 16 and the exhaust plate 17 are both close to the inner wall of the cabinet 1. The cabinet 1 is also provided with a driving component for driving the exhaust plate 17 and the air extraction plate 16 to move. The cabinet 1 is fixed with a horizontal guide plate 18 at the bottom of the air extraction plate 16, and a horizontal guide plate 18 is also fixed at the top of the exhaust plate 17. The guide plate 18 can provide stable guidance for the movement of the air extraction plate 16 and the exhaust plate 17, and a through hole is opened through the air guide plate to facilitate airflow.

[0031] Furthermore, the driving assembly includes a driving rack 171, a driven rack 161, a linkage gear 3 and a cam 4. The driving rack 171 is horizontally fixed to the lower part of the exhaust plate 17, and the driven rack 161 is horizontally fixed to the top of the air extraction plate 16. The driving rack 171 and the driven rack 161 correspond to each other in position. The linkage gear 3 is rotatably connected between the driving rack 171 and the driven rack 161, and is meshed with the driving rack 171 and the driven rack 161 at the same time. The upper and lower side walls of the partition plate 13 are provided with clearance grooves corresponding to the positions of the driving rack 171 and the driven rack 161, and the driving rack 171 and the driven rack 161 are horizontally slidably connected in the clearance grooves.

[0032] Reference Figure 2 and Figure 3The cam 4 is rotatably connected to the side of the exhaust plate 17 away from the porous plate 2, and the rotation axis is parallel to the rotation axis of the linkage gear 3. A driving member 41 for driving the cam 4 to rotate is fixed on the partition plate 13. The driving member 41 can be a small servo motor. A clearance groove for the cam 4 to rotate is provided at the position corresponding to the cam 4 on the partition plate 13 to avoid the interference of the partition plate 13 on the cam 4 when the cam 4 rotates. The axis of the cam 4 corresponds to the horizontal height of the driving rack 171, and the side wall of the cam 4 is in sliding contact with one end of the driving rack 171. During the rotation of the cam 4, the driving rack 171 can be pushed to slide in the horizontal direction. The driving rack 171 drives the driven gear to slide through the linkage gear 3, thereby realizing the reverse movement between the suction plate 16 and the exhaust plate 17. In other embodiments of the present application, a roller corresponding to the cam 4 can be rotatably connected to the side wall of the driving rack 171, and the side wall of the cam 4 is in direct sliding contact with the side wall of the roller, which can reduce the contact friction between the cam 4 and the driving rack 171.

[0033] The end of the driving rack 171 away from the cam 4 is connected to a reset elastic member 21, which may be a compression spring, and is used to restore the position of the driving rack 171. In other embodiments of the present application, a telescopic rod may be inserted into the reset elastic member 21, and the two ends of the telescopic rod are respectively fixed to the driving rack 171 and the porous plate 2. When the driving rack 171 moves, the telescopic rod will be correspondingly extended and retracted. At the same time, the telescopic rod can provide support for the compression and release of the reset elastic member 21, thereby improving the stability of the retraction of the reset elastic member 21.

[0034] When the cam 4 rotates, it can push the driving rack 171 to slide. When the air extraction plate 16 moves in the direction away from the module storage area 11, the space between the air extraction plate 16 and the porous plate 2 gradually increases, and the external cold air can be actively drawn into the cabinet 1, thereby accelerating the speed of cold air entering. When the air extraction plate 16 moves in the direction away from the module storage area 11, the exhaust plate 17 moves in the direction close to the porous plate 2 through the gear rack structure, so that the space between the exhaust plate 17 and the porous plate 2 gradually decreases, thereby actively discharging hot air from the air outlet 15, thereby accelerating the speed of cold air entering. The rate of hot air discharge is accelerated; when the air extraction plate 16 moves toward the direction close to the porous plate 2, the exhaust plate 17 moves away from the porous plate 2. At this time, the air extraction plate 16 actively pushes the cold air from bottom to top into the module placement area to accelerate the speed of the cold air movement. At the same time, the exhaust plate 17 actively draws the cold air from the lower layer of the module placement area to the upper layer, further accelerating the air flow circulation. The reciprocating movement of the air extraction plate 16 and the exhaust plate 17 in the cabinet 1 can effectively promote the intake of cold air and the discharge of hot air, thereby effectively improving the heat dissipation effect of the cabinet without adding a fan. The driving rack 171 will compress the reset elastic member 21 during the movement close to the porous plate 2. At this time, the reset elastic member 21 is deformed under pressure and stores elastic potential energy. When the cam 4 continues to rotate, the elastic potential energy stored in the reset elastic member 21 can drive the driving rack 171 to move in the opposite direction to achieve reset, so that the driving rack 171 can reciprocate in the horizontal direction.

[0035] Reference Figure 3 and Figure 4 , a horizontal isolation plate 5 is fixed to the cabinet 1 at a position corresponding to the partition plate 13 in the module placement area, and the side walls of the isolation plate 5 are in contact with the inner wall of the cabinet 1. The isolation plate 5 is provided with ventilation holes 51 in the vertical direction, and a stop plate 52 is horizontally slidably connected inside the isolation plate 5. A slide groove 53 for the stop plate 52 to slide is provided inside the isolation plate 5, and the stop plate 52 is inserted into the slide groove 53. In the embodiment of the present application, three rows of ventilation holes 51 are provided, and three are provided in each row. Three spaced blocking strips 521 are integrally formed on the stop plate 52. The three blocking strips 521 correspond to the three rows of ventilation holes 51, and the width of the blocking strips 521 is greater than the aperture of the ventilation holes 51. One end of the driving rack 171 is fixedly connected to the stop plate 52 through a connecting rod 54, so that the stop plate 52 can move synchronously with the driving rack 171.

[0036] When the exhaust plate 17 moves toward the porous plate 2, the stop plate 52 follows the movement, and the three blocking strips 521 respectively block the three rows of ventilation holes 51, so that the module storage area 11 is divided into two parts separated from each other. Since the stop plate 52 blocks the ventilation holes 51, the hot air will not move downward, so that the exhaust plate 17 can completely discharge the hot air in the upper layer out of the cabinet, avoiding the hot air from moving downward and prolonging the time it stays inside the cabinet. On the contrary, when the exhaust plate 17 moves away from the porous plate 2, the stop plate 52 follows the movement, and the blocking strips 521 move away from the ventilation holes 51, so that the ventilation holes 51 are connected and the airflow starts to flow in the cabinet body 1 again.

[0037] Reference Figure 5 The cabinet 1 has multiple layers of placement plates 6 fixed in the vertical direction in the module storage area 11, and a liquid cooling module 61 is fixed in each layer of placement plates 6. The upper and lower sides of the power module 111 are placed close to the liquid cooling module 61. A serpentine liquid cooling channel is provided inside the liquid cooling module 61. The inlet and outlet of the liquid cooling channel corresponding to the liquid cooling module 61 are both provided with liquid cooling pipes 62, and the liquid cooling pipes 62 are connected to the liquid cooling channel. A liquid cooling circulation box 7 is fixed on the top of the cabinet 1. A refrigeration component and a circulation component are arranged in the liquid cooling circulation box 7 to circulate the refrigerant in the cabinet 1. Since the refrigeration component and the circulation component are both conventional structures, they will not be described here.

[0038] Independent main liquid cooling inlet pipes 71 and main liquid cooling outlet pipes 72 are fixed to the two sides of the corresponding liquid cooling modules 61 in the module storage area 11, and the tops of the main liquid cooling inlet pipes 71 and the main liquid cooling outlet pipes 72 are connected to the liquid cooling circulation box 7. The inlet end of the liquid cooling pipe 62 corresponding to each liquid cooling module 61 is connected to the main liquid cooling inlet pipe 71, and the outlet end of the liquid cooling pipe 62 corresponding to each liquid cooling module 61 is connected to the main liquid cooling outlet pipe 72, so that the refrigerant can flow from the main liquid cooling pipe into the liquid cooling pipe 62, and then flow from the liquid cooling pipe 62 through the liquid cooling channel in the liquid cooling module 61, and finally flow back from the main liquid cooling outlet pipe 72 to the liquid cooling circulation box 7 to complete the complete cycle. At the same time, the liquid cooling pipe 62 corresponding to each liquid cooling module 61 is fixed with an isolation valve 73 at the inlet end. When the power module 111 is not placed in some liquid cooling modules 61, the corresponding liquid cooling module 61 can be shielded by the isolation valve 73, thereby reducing the power consumption of the equipment. When air cooling is not enough to reduce the temperature of the power module 111, the liquid cooling module 61 is started. Since the power module 111 is in close contact with the liquid cooling module 61, the liquid cooling module 61 can take away the high temperature on the surface of the power module 111, thereby further reducing the temperature inside the cabinet.

[0039] The implementation principle of a UPS cabinet in the embodiment of the present application is as follows: when the air extraction plate 16 moves away from the module storage area 11, the space between the air extraction plate 16 and the porous plate 2 gradually increases, and the external cold air can be actively drawn into the cabinet body 1, thereby accelerating the speed of cold air entering. When the air extraction plate 16 moves away from the module storage area 11, the exhaust plate 17 moves toward the porous plate 2, so that the space between the exhaust plate 17 and the porous plate 2 gradually decreases, thereby actively exhausting the hot air from the air outlet 15, thereby accelerating the rate of hot air exhaust. When moving toward the porous plate 2, the exhaust plate 17 moves away from the porous plate 2. At this time, the air extraction plate 16 actively pushes the cold air into the module placement area from bottom to top, accelerating the speed of the cold air movement. At the same time, the exhaust plate 17 actively draws the cold air from the lower layer of the module placement area to the upper layer, further accelerating the air flow circulation. The reciprocating motion of the air extraction plate 16 and the exhaust plate 17 in the cabinet 1 can effectively promote the intake of cold air and the discharge of hot air. At the same time, when the air cooling method is not sufficient to meet the heat dissipation requirements of the cabinet, the liquid cooling module 61 is started to perform liquid cooling on the power module 111.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
