Device for regulating cooling airflow inside network cabinets

Abstract

This invention discloses a device for regulating cooling airflow within a network cabinet, comprising a cabinet body with door frames and side frames on the sides and front. A support assembly is installed inside the cabinet, and a negative pressure assembly is connected to the support assembly. In this device, the network equipment placed on the grid plate has its bottom in a gap state, increasing the area of ​​the negative pressure at the bottom and maximizing the extraction of heat from the bottom of the network equipment. When the negative pressure pump is working, it can draw gas from the exhaust pipe, thereby drawing airflow from the bottom of the grid plate. The heat generated by the network equipment on the grid plate is extracted, and the airflow is discharged to the outside of the cabinet through a separate channel. This ensures that even when the conductive sheet wears, the two remain in close contact, thus sending electrical energy and signals from the controller to the motor, which in turn drives the fan to rotate for heat dissipation.

Description

Technical Field

[0001] This invention relates to the field of cooling technology for network cabinets, specifically to a device for regulating cooling airflow within a network cabinet. Background Technology

[0002] Network cabinets are generally made of thin steel plates, steel profiles of various cross-sectional shapes, aluminum profiles, and various engineering plastics. In addition to welding and screw connections, the frame of a network cabinet also employs adhesive bonding.

[0003] Network cabinets are critical equipment in communication systems, and most are located directly outdoors. Changes in the external environment can affect the operational quality of network equipment. Current technology uses large temperature control devices to regulate the operating environment of network cabinets, but this method is energy-intensive and costly. Furthermore, remote engineers cannot monitor the operating status, mains power status, and environmental conditions of the network cabinets, resulting in inadequate protection for the communication equipment.

[0004] Server racks typically have two ventilation methods: front-in / rear-out and top-in / bottom-out. However, network equipment often has a left-in / right-out ventilation method, which can easily lead to poor ventilation and cooling, causing the network equipment to overheat. Summary of the Invention

[0005] The purpose of this invention is to provide a device for regulating the cooling airflow inside a network cabinet. When the negative pressure pump is working, it can draw gas from the exhaust pipe, thereby drawing airflow from the bottom of the network panel. Heat generated by the network equipment on the network panel is extracted, and the airflow is discharged to the outside of the cabinet through a separate channel. Even when the conductive sheet wears, the two remain in close contact, thus transmitting the controller's electrical energy and signals to the motor, which in turn drives the fan to rotate for heat dissipation. This invention solves the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for regulating cooling airflow inside a network cabinet, comprising a cabinet body, wherein door frames and side frames are provided on the side and front of the cabinet body, a support assembly is installed inside the cabinet body, and a negative pressure assembly is connected to the support assembly.

[0007] Furthermore, the door frame and side frame are connected to the front door panel and side door panel via hinges, and heat dissipation components are connected to the top of the front door panel and side door panel.

[0008] Furthermore, the support assembly includes a lead screw, a sleeve, an upper limit ring, a lower limit ring, a knob, a transmission rod, a gear ring, a gear, and a horizontal plate. The lead screw is fixed at a corner of the cabinet, and a sleeve is engaged on the lead screw. The upper limit ring and the lower limit ring are fixed side by side on the outer wall of the sleeve. The horizontal plate is inserted into the annular groove formed between the upper limit ring and the lower limit ring. The gear ring is sleeved on the outside of the sleeve.

[0009] One end of the knob is fixed to the transmission rod, the other end of the transmission rod is inserted into the horizontal plate and connected to the gear. The gear meshes with the gear ring, and one end of the horizontal plate is penetrated by the sleeve, while the other two ends of the horizontal plate are fitted onto the slide rod.

[0010] Furthermore, the negative pressure assembly includes a negative pressure plate, a negative pressure pipe, a cylinder, a mesh plate, and an exhaust pipe. The cylinder is located on both sides of the horizontal plate, and the extension rod of the cylinder is connected to both ends of the negative pressure plate. A mesh plate is placed on the negative pressure plate.

[0011] The upper and lower sides of the mesh plate are connected to negative pressure pipes. The inside of the mesh plate is conical, and the negative pressure pipes at the upper and lower positions are connected to the conical holes of the mesh plate.

[0012] The exhaust pipes are provided in multiple sets and are fixed to the inner wall of the cabinet at equal intervals. The top of the exhaust pipe at the top is sealed, and the exhaust pipe at the bottom extends to the outside of the cabinet and is connected to the negative pressure pump. Adjacent exhaust pipes are inserted by negative pressure pipes at the upper and lower positions, and the negative pressure pipes are equipped with flow regulating components.

[0013] Furthermore, the heat dissipation assembly includes a heat dissipation frame, a heat dissipation mesh, a fan, a rotating shaft, a motor, and a rotating power supply assembly. Circular holes are provided on the front door panel and the side door panel. The heat dissipation frame is installed in the circular holes. The center of the heat dissipation frame is fixed to the motor by bolts. The shaft of the motor is connected to the rotating shaft by a shaft key. A fan is connected to the port of the rotating shaft. The airflow generated by the fan is directed towards the cabinet.

[0014] The rotating power supply assembly is placed on the hinges of the front door panel and the side door panel, and the rotating power supply assembly is connected to the motor.

[0015] Furthermore, the rotating energized assembly includes an upper guide post, a lower guide post, an upper spring, a lower spring, and a conductive plate. The upper and lower guide posts are respectively positioned at the top and bottom of the hinge. The upper and lower guide posts slide relative to each other, and the upper and lower guide posts are respectively connected to the conductive plates through the upper and lower springs. The conductive plates corresponding to the upper and lower springs are in contact with each other, and the conductive plates are electrically connected to the upper and lower guide posts through wires.

[0016] The wires connected to the upper guide column run along the inner wall of the cabinet and are electrically connected to the controller, while the wires connected to the lower guide column run along the surface of the front door panel and the side door panel and are electrically connected to the motor.

[0017] Furthermore, the flow regulation component includes a flow shaft and an adjustment plate. The flow shaft passes through the bearings at both ends of the negative pressure pipe, and the adjustment plate is connected to the outer wall of the flow shaft. The rotation of the adjustment plate changes the flow rate of the airflow through the negative pressure pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This device regulates the cooling airflow inside the network cabinet. The network equipment placed on the grid plate has gaps at the bottom, increasing the area of ​​negative pressure at the bottom and maximizing the extraction of heat from the bottom of the network equipment. When the negative pressure pump is working, it can draw gas from the exhaust pipe, which in turn draws airflow from the bottom of the grid plate. The heat generated by the network equipment on the grid plate is extracted and effectively improved by the horizontal cooling airflow. A separate channel is used to discharge the airflow to the outside of the cabinet.

[0020] This device regulates the cooling airflow within the network cabinet. The upper and lower guide pillars slide relative to each other and are connected to conductive plates via upper and lower springs, respectively. The insulated upper and lower springs allow the two conductive plates to contact each other. The elastic setting ensures that even when the conductive plates wear, they maintain close contact, thereby transmitting the controller's electrical energy and signals to the motor, which in turn drives the fan to rotate for heat dissipation.

[0031] 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.

[0032] Please see Figure 1-3 The device for regulating the cooling airflow inside the network cabinet includes a cabinet 1. The cabinet 1 has a door frame 11 and a side frame 12 on its side and front. The door frame 11 and the side frame 12 are provided to facilitate opening the cabinet 1 from the front and the side. A support component 2 is installed inside the cabinet 1, and a negative pressure component 3 is connected to the support component 2.

[0033] The door frame 11 and the side frame 12 are connected to the front door panel 111 and the side door panel 121 by hinges. The front door panel 111 and the side door panel 121 are connected to a heat dissipation component 4. The front door panel 111 and the side door panel 121 can be rotated by hinges. The heat dissipation component 4 is provided on the front door panel 111 and the side door panel 121 for dissipating heat from the front and the side to the inside of the cabinet 1.

[0034] Please see Figure 4 The support assembly 2 includes a lead screw 21, a sleeve 22, an upper limit ring 23, a lower limit ring 24, a knob 25, a transmission rod 26, a gear ring 27, a gear 28, and a horizontal plate 29. The lead screw 21 is fixed at a corner of the cabinet 1. The sleeve 22 is engaged with the lead screw 21. The upper limit ring 23 and the lower limit ring 24 are fixed side by side on the outer wall of the sleeve 22. The horizontal plate 29 is inserted into the annular groove formed between the upper limit ring 23 and the lower limit ring 24. The upper limit ring 23 and the lower limit ring 24 rotate synchronously with the sleeve 22. When the upper limit ring 23 and the lower limit ring 24 rotate, they restrict the horizontal plate 29. The gear ring 27 is sleeved on the outside of the sleeve 22.

[0035] One end of the knob 25 is fixed to the transmission rod 26, and the other end of the transmission rod 26 is inserted into the horizontal plate 29 and connected to the gear 28. Rotating the knob 25 drives the gear 28 to rotate, and the gear 28 meshes with the gear ring 27. When the knob 25 rotates, it drives the gear ring 27 to rotate synchronously. One end of the horizontal plate 29 is penetrated by the sleeve 22, and the other two ends of the horizontal plate 29 are fitted onto the slide rod. When the gear ring 27 rotates, it drives the gear ring 27 to rotate. Since the position of the lead screw 21 is fixed, the rotation of the gear ring 27 causes the sleeve 22 to rotate as well. The rotation of the sleeve 22 will cause it to rise or fall along the lead screw 21, and the slide rod is provided to limit the rise or fall of the horizontal plate 29.

[0036] Please see Figure 3 and Figure 5 The negative pressure assembly 3 includes a negative pressure plate 31, a negative pressure pipe 32, a cylinder 33, a mesh plate 34, and an exhaust pipe 35. The cylinder 33 is located on both sides of the horizontal plate 29, which fixes the position of the cylinder 33. The telescopic rod of the cylinder 33 is connected to both ends of the negative pressure plate 31. The mesh plate 34 is placed on the negative pressure plate 31. The cylinder 33 drives the negative pressure plate 31 to rise or fall. The thickness of the mesh plate 34 is not less than 4cm. The hole pattern of the mesh plate 34 allows the bottom of the network machine equipment placed on the mesh plate 34 to be in a gap state, increasing the area of ​​the bottom negative pressure and maximizing the extraction of heat from the bottom of the network machine equipment.

[0037] The upper and lower sides of the mesh plate 34 are connected to the negative pressure pipe 32. The inside of the mesh plate 34 is conical, and the negative pressure pipes 32 at the upper and lower positions are connected to the conical holes of the mesh plate 34. The conical holes of the mesh plate 34 facilitate the concentration of airflow so that it can be drawn by the negative pressure pipe 32.

[0038] Multiple sets of exhaust pipes 35 are provided and fixed at equal intervals on the inner wall of the cabinet 1. The top of the exhaust pipe 35 is sealed, and the bottom of the exhaust pipe 35 extends to the outside of the cabinet 1 and connects to the negative pressure pump 6. Adjacent exhaust pipes 35 are inserted by negative pressure pipes 32 at the upper and lower positions. The negative pressure pipes 32 are equipped with flow regulating components 5. The negative pressure pipes 32 are driven to move up and down by cylinders 33. During the movement, the negative pressure pipes 32 at the upper and lower positions can always maintain a sealed state with the exhaust pipes 35. When the negative pressure pump 6 is working, it can draw gas from the exhaust pipes 35. Thus, the negative pressure pipes 32 also draw airflow from the bottom of the mesh plate 34. The heat generated by the mesh machine equipment on the mesh plate 34 is drawn off and the airflow is discharged to the outside of the cabinet 1 through a separate channel.

[0039] Please see Figure 6-7The heat dissipation assembly 4 includes a heat dissipation frame 41, a heat dissipation mesh 42, a fan 43, a rotating shaft 44, a motor 45, and a rotating power supply assembly 46. Circular holes are provided on the front door panel 111 and the side door panel 121. The heat dissipation frame 41 is installed in the circular holes. The center of the heat dissipation frame 41 is fixed to the motor 45 by bolts. The shaft of the motor 45 is connected to the rotating shaft 44 by a shaft key. The fan 43 is connected to the port of the rotating shaft 44. The airflow generated by the fan 43 is directed towards the cabinet 1. The motor 45 drives the fan 43 to rotate. After the airflow generated by the fan 43 blows into the cabinet 1, it increases the airflow inside the cabinet 1, so that the airflow around the cabinet 1 can be changed, thereby removing the heat generated by the equipment in all directions.

[0040] The rotating power supply assembly 46 is placed on the hinges of the front door panel 111 and the side door panel 121. The rotating power supply assembly 46 is connected to the motor 45. The rotating power supply assembly 46 allows the front door panel 111 and the side door panel 121 to rotate while still being powered.

[0041] Please see Figure 8 The rotating energized assembly 46 includes an upper guide post 461, a lower guide post 462, an upper spring 463, a lower spring 464, and a conductive plate 465. The upper guide post 461 and the lower guide post 462 are respectively positioned at the top and bottom of the hinge. The upper guide post 461 and the lower guide post 462 slide relative to each other. The upper guide post 461 and the lower guide post 462 are respectively connected to the conductive plate 465 through the upper spring 463 and the lower spring 464. The conductive plates 465 corresponding to the upper spring 463 and the lower spring 464 are in contact with each other. The conductive plates 465 are electrically connected to the upper guide post 461 and the lower guide post 462 through wires. The upper guide post 461 and the lower guide post 462 are distributed at different positions on the hinge. One of the upper guide post 461 and the lower guide post 462 is connected to the cabinet body 1, and the other is connected to the front door panel 111 and the side door panel 121. When the front door panel 111 and the side door panel 121 rotate, they drive the lower guide post 462.

[0042] Please see Figure 9 The wires connected to the upper guide post 461 run along the inner wall of the cabinet 1 and are electrically connected to the controller. The wires connected to the lower guide post 462 run along the surface of the front door panel 111 and the side door panel 121 and are electrically connected to the motor 45. Through the insulated upper spring 463 and lower spring 464, the two conductive pieces 465 can contact each other. The elastic setting allows the two to maintain a tight contact even when the conductive pieces 465 are worn, so that the controller's electrical energy and signals are sent to the motor 45, and the motor 45 drives the fan 43 to rotate for heat dissipation.

[0043] The flow regulation component 5 includes a flow shaft 51 and an adjustment plate 52. The flow shaft 51 passes through the bearings at both ends of the negative pressure pipe 32. The adjustment plate 52 is connected to the outer wall of the flow shaft 51. The adjustment plate 52 rotates to change the flow rate of the airflow through the negative pressure pipe 32. By changing the internal diameter of the negative pressure pipe 32, the internal airflow and flow rate are changed. When the temperature inside the cabinet 1 is high, the adjustment plate 52 is rotated to the vertical direction to extract the internal gas at the maximum flow rate for heat dissipation. When the temperature is low, the flow rate of the internal gas is reduced.

[0044] In summary: This device for regulating cooling airflow within the network cabinet features an upper limit ring 23 and a lower limit ring 24 that rotate synchronously with the sleeve 22. During rotation, the upper limit ring 23 and lower limit ring 24 restrict the horizontal plate 29. A gear ring 27 is fitted over the sleeve 22. Rotation of the knob 25 causes the gear ring 27 to rotate synchronously, which in turn causes the sleeve 22 to rotate. The rotation of the sleeve 22 causes it to rise or fall along the lead screw 21. A sliding rod further restricts the rise or fall of the horizontal plate 29. The perforated design of the mesh plate 34 allows for the placement of... The bottom of the network equipment is in a gap state, which increases the area of ​​the negative pressure at the bottom and can maximize the extraction of heat from the bottom of the network equipment. The negative pressure pipe 32 is driven up and down by the cylinder 33. During the movement, the negative pressure pipe 32 in the upper and lower positions can always maintain a sealed state with the exhaust pipe 35. When the negative pressure pump 6 is working, it can extract the gas in the exhaust pipe 35. Thus, the negative pressure pipe 32 also extracts the airflow at the bottom of the mesh plate 34. The heat generated by the network equipment on the mesh plate 34 is extracted and discharged to the outside of the cabinet 1 through a separate channel. The upper guide post 461 and the lower guide post 462 slide relative to each other, and the upper guide post 461 and the lower guide post 462 are connected to the conductive sheet 465 by the upper spring 463 and the lower spring 464 respectively. The two conductive sheets 465 can contact each other through the insulated upper spring 463 and the lower spring 464. The elastic setting allows the two to maintain close contact even when the conductive sheets 465 are worn, so that the electrical energy and signal of the controller can be sent to the motor 45, and the motor 45 drives the fan 43 to rotate for heat dissipation.
