Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a server cabinet for cloud computing. Background Art

[0002] Cloud computing is a type of distributed computing. It automatically splits huge data computing programs into countless smaller subprograms through the network, and then sends the results back to the user after searching, computing and analyzing by a large system composed of multiple servers. Cloud computing mainly relies on servers to process data, and when the server is working, its internal devices will generate a lot of heat. The rise in server temperature will affect its performance, so the server cabinet needs to have good heat dissipation performance.

[0003] Conventional servers generally use fans to drive the air inside the cabinet and the air outside the cabinet to dissipate heat from the components inside the cabinet. However, the components inside the cabinet are installed relatively tightly, so the gaps between the components are small, resulting in poor air circulation. As a result, the temperature inside the cabinet may be uneven, and the temperature in some areas may be too high. There are also some server cabinets that dissipate heat through water cooling. For example, the Chinese patent with announcement number: CN118382278B discloses a server cabinet and a server that dissipate heat through water cooling. However, when leakage occurs at the connection of the water-cooling pipe, the coolant will corrode the components inside the cabinet, affecting the stability of the server, so further improvements can be made.

DETAILED DESCRIPTION

[0018] In the description of the present application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 3 A server cabinet for cloud computing includes a cabinet shell 100, four groups of columns 200 are fixedly installed inside the cabinet shell 100, a plurality of pallet assemblies 300 are fixedly installed between the four groups of columns 200 by bolts, and components of the server are installed on the pallet assemblies 300. A storage cavity is provided inside each pallet assembly 300, through holes 400 are arranged in an array on the top of the pallet assembly 300, an air inlet groove 500 is provided on the front side of the pallet assembly 300, the through holes 400 and the air inlet groove 500 are both connected to the storage cavity, and the storage cavity is connected to the inside of the cabinet shell 100 through the through holes 400 and the air inlet groove 500. Thus, a channel for air flow is reserved between the components of the server through the storage cavity.

[0021] The storage cavity is provided with a built-in flow guide component 600, both ends of which are passed out from the rear end of the support plate component 300 and penetrate the back of the cabinet shell 100, and the joint inside the built-in flow guide component 600 is located inside the storage cavity, and the leaked coolant is temporarily stored in the storage cavity. An external flow guide component 700 is fixedly installed on the back of the cabinet shell 100, and both ends of the built-in flow guide component 600 are connected to the external flow guide component 700, and coolant circulates inside the external flow guide component 700 and the built-in flow guide component 600. Thus, heat conduction is carried out through the support plate component 300, so that the heat emitted by the device of the server is conducted to the coolant. During the circulation of the coolant inside the built-in flow guide component 600 and the external flow guide component 700, since the external flow guide component 700 is outside the cabinet shell 100, it can be fully in contact with the external air, so that when the coolant flows through the external flow guide component 700, the heat inside the coolant can be conducted to the outside air. In addition, since the external guide assembly 700 is located outside the cabinet housing 100 , the joint between the internal guide assembly 600 and the external guide assembly 700 is also located outside the cabinet housing 100 , thereby preventing the leaking coolant from damaging the components inside the cabinet housing 100 .

[0022] An exhaust assembly 800 is provided at the rear side of the cabinet housing 100, and a pipe is connected between the rear side of each pallet assembly 300 and the exhaust assembly 800, and the storage cavity is connected to the inside of the exhaust assembly 800 through the pipe; a driving assembly 900 is provided at the back of the cabinet housing 100, and the driving assembly 900 is used to drive the exhaust assembly 800 to discharge the air inside the storage cavity to the outside of the cabinet housing 100. In this process, the hot air inside the cabinet housing 100 is sucked into the storage cavity through the through hole 400 and the air inlet groove 500, and then the hot air inside the storage cavity is blown to the surface of the external guide assembly 700 through the pipe and the exhaust assembly 800, which promotes the air flow inside the cabinet housing 100, while accelerating the air flow speed around the external guide assembly 700, and further accelerating the heat dissipation effect of the internal coolant of the external guide assembly 700.

[0023] When the air in the storage chamber flows, the coolant dripped into the storage chamber is discharged along with the air flow.

[0024] In addition, when the exhaust assembly 800 draws air from the storage chamber, the through hole 400 is in a negative pressure state, which adsorbs the components of the server on the upper surface of the pallet assembly 300, ensuring that the components of the server fit tightly with the pallet assembly 300, thereby ensuring the heat conduction effect.

[0025] See also Figure 4The cabinet housing 100 has a cabinet door 101 hinged on the front side, and a rear baffle 102 is provided on the back of the cabinet housing 100. Connecting strips 103 are integrally formed on both sides of the rear baffle 102. The cross section of the connecting strip 103 is L-shaped. Through the setting of the connecting strip 103, an area for installing the external guide assembly 700 is formed on the back of the rear baffle 102. Ventilation slots 104 are arranged in arrays on both sides of the cabinet housing 100. Filter cotton sheets 105 are fixedly installed on both sides of the cabinet housing 100. The filter cotton sheets 105 cover the openings of the ventilation slots 104. When the exhaust assembly 800 draws the air inside the cabinet housing 100 into the external environment, the inside of the cabinet housing 100 is in a negative pressure state, so that the outside air can enter the inside of the cabinet housing 100 through the filter cotton sheets 105 and the ventilation slots 104 under the action of the air pressure difference. The setting of the filter cotton sheets 105 prevents dust, moisture, etc. from entering the inside of the cabinet housing 100.

[0026] See also Figure 5-Figure 7 The support plate assembly 300 includes a liquid storage tank 301, a rubber ring 302 and a sealing cover 303. The sealing cover 303 and the liquid storage tank 301 are clamped on both sides of the rubber ring 302. The liquid storage tank 301, the rubber ring 302 and the sealing cover 303 are fixed by screws, and a countersunk hole is opened on the top of the sealing cover 303 to accommodate the screw head so that the top of the sealing cover 303 remains flat.

[0027] A storage cavity is formed between the liquid reservoir 301 and the sealing cover 303, a through hole 400 is provided through the sealing cover 303, and an air inlet groove 500 is provided in the upper half of the front side of the liquid reservoir 301, so that the air inlet groove 500 is away from the bottom wall of the liquid reservoir 301, and the coolant inside the storage cavity is prevented from overflowing from the air inlet groove 500. Angle brackets are welded at the four corners of the liquid reservoir 301, and mounting holes 201 are provided in an array on the surface of the column 200 along its length direction, and the angle brackets at the corners of the liquid reservoir 301 are mounted on the column 200 by bolts.

[0028] See also Figure 7 The bottom of the sealing cover 303 is integrally formed with a boss 304, and the through hole 400 penetrates the boss 304. A wiring groove 305 is provided at the bottom of the boss 304. The cross section of the wiring groove 305 is semicircular. The wiring groove 305 is composed of a row of linear grooves and a plurality of C-shaped grooves. The leftmost and rightmost linear grooves penetrate to the rear end of the boss 304, and the ends of two adjacent linear grooves are connected through the C-shaped groove. The wiring groove 305 is used to lay the built-in guide component 600, so that the built-in guide component 600 fits tightly with the boss 304 to ensure the heat conduction effect.

[0029] A plurality of support blocks 306 are fixedly mounted on the bottom wall of the liquid storage tank 301, the top of the support block 306 is an arc-shaped surface, the boss 304 and the support block 306 are clamped on the surface of the built-in flow guide component 600, and the two ends of the built-in flow guide component 600 pass through the rear side of the liquid storage tank 301. Thus, the built-in flow guide component 600 is fixed and kept in close contact with the boss 304.

[0030] See also Figure 6-Figure 7 The built-in flow guide component 600 includes a heat-conducting copper tube 601 laid inside the wiring groove 305, and inserting tubes 602 are welded at both ends of the heat-conducting copper tube 601. The inserting tube 602 is located inside the storage cavity, and a connecting hose 603 is sleeved on the outside of the inserting tube 602. A clamp 604 is arranged on the outside of the connecting hose 603. The clamp 604 and the inserting tube 602 are clamped on the inside and outside of the connecting hose 603 respectively, and the connecting hose 603 passes through the rear end of the liquid storage tank 301 and the rear baffle 102. Therefore, the connection between the heat-conducting copper tube 601 and the connecting hose 603 is located inside the storage cavity, and the leaked coolant is stored in the storage cavity.

[0031] See also Figure 8-Figure 10 The external flow guide assembly 700 includes a return main pipe 701 and a liquid inlet main pipe 702. The return main pipe 701 and the liquid inlet main pipe 702 are located at the rear side of the cabinet housing 100, and the return main pipe 701 and the liquid inlet main pipe 702 are respectively fixedly installed on the opposite sides of the two groups of connecting strips 103. The connecting hose 603 on the left is connected to the return main pipe 701, and the connecting hose 603 on the right is connected to the liquid inlet main pipe 702. A flow guide copper pipe 703 is connected between the bottom end of the return main pipe 701 and the top end of the liquid inlet main pipe 702. A heat dissipation part 704 is arranged in the middle of the flow guide copper pipe 703. The heat dissipation part 704 has a row of vertical pipes. A suction pump 705 is connected to the flow guide copper pipe 703. By arranging the suction pump 705 outside the cabinet housing 100, the heat generated by the suction pump 705 when working is prevented from affecting the components inside the cabinet housing 100.

[0032] See also Figure 8-Figure 10 The exhaust assembly 800 includes a mounting cover 801 fixedly mounted on the middle of the front side of the rear baffle 102. A blowing port 802 is provided through the rear baffle 102. The mounting cover 801 is connected to the outside air through the blowing port 802. The blowing port 802 is directed toward the vertical pipe of the heat dissipation part 704. A shielding ring 803 is welded to the inner wall of the opening of the mounting cover 801. The inner diameter of the shielding ring 803 gradually decreases from front to back.

[0033] Two groups of air inlet pipes 804 are fixed in an array on the circumferential surface of the mounting cover 801. The air inlet pipes 804 are arranged along the tangent direction of the mounting cover 801. The rear side of each liquid storage tank 301 is connected to an air guide pipe 806, and the other end of the air guide pipe 806 is connected to the air inlet pipe 804. An exhaust fan 805 is rotatably connected at the center of the mounting cover 801, and a shielding ring 803 shields the rear side of the blades of the exhaust fan 805. Therefore, when the exhaust fan 805 rotates, the air inside the storage chamber enters the interior of the mounting cover 801 through the air guide pipe 806 and the air inlet pipe 804, and then passes through the opening of the shielding ring 803 and blows onto the vertical pipe of the heat dissipation part 704. The air flow speed around the vertical pipe of the heat dissipation part 704 is increased.

[0034] See also Figure 2 and Figure 8-Figure 10 The driving assembly 900 includes a motor 901, a rotating shaft 902 is fixedly installed at the output end of the motor 901, the rotating shaft 902 penetrates and is rotatably connected to the rear baffle 102, a driving pulley 903 is fixedly installed at the rear end of the rotating shaft 902, a driven pulley 904 is coaxially fixed to the front side of the exhaust fan 805, the driven pulley 904 is located at the front side of the mounting cover 801, and the driving pulley 903 and the driven pulley 904 are connected by an annular belt 905. Through the transmission effect of the driving pulley 903, the driven pulley 904 and the annular belt 905, when the motor 901 drives the rotating shaft 902 to rotate, the exhaust fan 805 is driven to rotate. The motor 901 is placed outside the cabinet housing 100 to prevent the heat generated by the motor 901 when working from affecting the components inside the cabinet housing 100.

[0035] A rotating disk 906 is fixedly mounted on the rotating shaft 902, so that the rotating disk 906 and the driving pulley 903 rotate synchronously. The rotating disk 906 is located at the rear side of the rear baffle 102, and an annular groove 907 is provided at the rear side of the rotating disk 906. A guide sleeve 908 is fixedly mounted at the rear side of the rear baffle 102, and a sliding arm 909 is slidably connected in the guide sleeve 908. The sliding arm 909 is guided by the guide sleeve 908 so that the sliding arm 909 can only move in the vertical direction. A sliding column 910 is fixedly mounted at the front side of the bottom end of the sliding arm 909, and the sliding column 910 is slidably connected in the annular groove 907. A scraper 911 is fixedly mounted at the front side of the top end of the sliding arm 909, and a socket is provided through the top array of the scraper 911, and the vertical penetration of the heat dissipation part 704 is plugged into the socket.

[0036] During the rotation of the turntable 906, the slide post 910 slides inside the annular groove 907. The turntable 906 is located at the inner wall of the annular groove 907 to squeeze the slide post 910 and drive the sliding arm 909 to move up and down along the guide sleeve 908. Thus, the scraper 911 is driven to slide back and forth along the vertical tube of the heat dissipation part 704. Since the air inside the storage chamber and the dripping coolant are blown to the surface of the heat dissipation part 704 through the exhaust assembly 800, the coolant droplets will adhere to the surface of the heat dissipation part 704; and after long-term use, dust will also adhere to the surface of the heat dissipation part 704. Thus, the heat exchange between the heat dissipation part 704 and the air is affected. Thus, the scraper 911 scrapes back and forth on the vertical tube of the heat dissipation part 704, and the water droplets, dust, etc. on the surface of the vertical tube of the heat dissipation part 704 are scraped off, thereby ensuring the heat dissipation effect of the heat dissipation part 704.

[0037] The annular groove 907 includes a small arc groove 9071, a large arc groove 9072 and two groups of inclined grooves 9073. The radius of the small arc groove 9071 is smaller than that of the large arc groove 9072. The ends of the small arc groove 9071 and the large arc groove 9072 are connected through the inclined groove 9073. When the sliding column 910 is in the large arc groove 9072, the distance between the sliding column 910 and the center of the rotating disk 906 is relatively far, and the scraper 911 is at a higher position; when the sliding column 910 is in the annular groove 907, the distance between the sliding column 910 and the center of the rotating disk 906 is relatively close, and the scraper 911 is at a lower position; when the sliding column 910 slides along the inclined groove 9073, the sliding arm 909 slides along the guide sleeve 908.

[0038] When in use, the motor 901 drives the rotating shaft 902 to rotate, driving the driving pulley 903 and the rotating disk 906 to rotate synchronously, and cooperates with the transmission function of the annular belt 905 and the driven pulley 904 to drive the exhaust fan 805 to rotate, so that the air inside the storage chamber enters the interior of the installation cover 801 through the air guide pipe 806 and the air inlet pipe 804, and then blows to the surface of the heat dissipation part 704 through the opening of the shielding ring 803; During this process, the air inside the cabinet housing 100 passes through the through hole 400 and the air inlet slot 500 to enter the storage cavity, and the outside air passes through the filter cotton sheet 105 and the ventilation slot 104 to enter the cabinet housing 100, thereby enhancing the circulation effect of the air inside the cabinet housing 100 and the outside air. The cooling liquid in the return main pipe 701 is driven by the suction pump 705 to pass through the guide copper tube 703 and enter the liquid inlet main pipe 702, and then enters the heat-conducting copper tube 601 through the right row of connecting hoses 603, and then flows back to the return main pipe 701 through the left row of connecting hoses 603, so that the cooling liquid circulates; The heat-conducting copper tube 601 is attached to the bottom of the boss 304, and the sealing cover 303 and the boss 304 cooperate with each other to conduct heat, so that the server components conduct heat to the coolant inside the heat-conducting copper tube 601. When the coolant passes through the heat dissipation part 704, it contacts with the outside air through the heat dissipation part 704, and conducts heat to the outside air. When leakage occurs at the connection between the heat-conducting copper tube 601 and the connecting hose 603, the leaked coolant is temporarily stored in the storage cavity and blown toward the surface of the heat dissipation portion 704 by the airflow inside the storage cavity. The leaked coolant is discharged to the outside of the cabinet housing 100; at the same time, the blown coolant adheres to the surface of the heat dissipation portion 704, which can absorb the heat of the heat dissipation portion 704, further enhancing the heat dissipation effect of the heat dissipation portion 704; During the rotation of the turntable 906, the slide post 910 slides along the annular groove 907. When the slide post 910 slides along the inclined groove 9073, the slide arm 909 slides along the guide sleeve 908, so that the scraper 911 moves along the vertical tube of the heat dissipation part 704 to scrape off the dust, liquid droplets, etc. on the surface of the heat dissipation part 704, thereby ensuring the heat dissipation effect of the heat dissipation part 704. In addition, during the sliding of the scraper 911 along the surface of the heat dissipation part 704, the liquid droplets attached to the heat dissipation part 704 will be transferred to the scraper 911, and as the scraper 911 moves, the liquid droplets are flattened on the surface of the heat dissipation part 704, so that a layer of water film is formed on the surface of the heat dissipation part 704, and the water film absorbs the heat on the surface of the heat dissipation part 704, further enhancing the heat dissipation effect on the surface of the heat dissipation part 704.
