Description

Technical Field

[0001] The present invention belongs to the technical field of server heat dissipation, and particularly relates to an emergency heat dissipation device for a server. Background Art

[0002] With the development of science and technology, computer equipment and supplies are becoming more and more widespread in daily life, and computer functions are becoming more and more powerful. A computer server is a high-performance computer. As a node of the network, it stores and processes data and information on the network, so it is also called the soul of the network. When a computer server works for a long time, it will generate heat. If heat dissipation is not carried out in time, the working efficiency of the computer server will be reduced.

[0003] Some solutions have also been proposed in the prior art. For example, a patent with the publication number CN111124082A discloses a heat dissipation device for a server, which includes a water tank that contains coolant and bears the server; a first conduit located on one side of the server, and one end of which is fluidly connected to the water tank; the coolant enters the cavity through the first conduit and returns to the water tank through the second conduit, and the coolant drives the impeller in the cavity to rotate, so as to drive the piston cylinder to continuously suck air through the air suction pipe and discharge air through the air discharge pipe, so as to dissipate heat from the server in all directions, making the heat dissipation of the computer server more comprehensive, and at the same time, it can also effectively reduce power consumption.

[0004] The heat dissipation forms of servers are mainly divided into two forms: air cooling and water cooling. Compared with water-cooled radiators, air-cooled radiators have a relatively simple structure and lower manufacturing costs, which is a more economical and practical choice. Since the fan sucks external air into the chassis when it sucks air from the outside, it is also easy to suck dust in the external air into the chassis. The dust will block the gaps between the blades of the heat dissipation fan and the heat sink, resulting in the inability to dissipate heat in time.

[0005] Therefore, the present invention provides an emergency heat dissipation device for a server. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An emergency heat dissipation device for a server according to the present invention includes a housing. A main board unit and a graphics card unit are fixedly installed inside the housing. A first fan unit is arranged below the graphics card unit, and the first fan unit is fixedly installed on the inner wall of the housing. A base is fixedly installed at the bottom of the housing. A filter screen is symmetrically and fixedly connected between the two bases. A cabinet door is arranged on one side of the housing. A collection component is arranged between the two filter screens. The collection component is used to collect the dust intercepted by the filter screen. A vibration component for driving the filter screen to remove dust is arranged outside the filter screen.

[0008] Preferably, the collection component includes a dust inlet chamber, which is fixedly installed above and between two filter screens. A dust inlet bin is fixedly connected to the bottom of the dust inlet chamber, and the dust inlet bin is located below the bottom side of the filter screens.

[0009] Preferably, both of the two filter screens are in an arc shape.

[0010] Preferably, the top of the dust inlet chamber is in a closed state. A dust falling box is fixedly connected to the bottom of the dust inlet chamber. The top and bottom of the dust falling box are both in an open state and the side surface is in a slope state.

[0011] Preferably, a collection box is arranged below the dust falling box, and the width of the collection box is the same as the width of the dust inlet chamber.

[0012] Preferably, two base plates are fixedly connected to the bottom of the housing. Both of the two base plates are fixedly connected between two bases. The two filter screens are located between the two base plates. The vibration component includes a plurality of hinge members. The shaft rods of every two hinge members are respectively fixedly connected to both ends of one side of the two filter screens. A plurality of extrusion blocks are arranged above the other side of each filter screen. A rotating rod is fixedly connected between the plurality of extrusion blocks on each side, and the rotating rods are all rotatably connected to one of the base plates.

[0013] Preferably, one end of one of the rotating rods is fixedly connected to a motor. The motor is fixedly installed on the top of the base plate. One end of each of the two rotating rods is fixedly connected to a transmission ring. A transmission belt is connected in transmission between the two transmission rings. Side connection plates are symmetrically and fixedly connected to the side surface of the dust falling box.

[0014] Preferably, an angle spring is fixedly connected between the bottom of the filter screen and the side connection plate.

[0015] Preferably, heat conduction tubes are fixedly connected to the surfaces of the main board unit and the graphics card unit.

The end of the heat conduction tube close to the main board unit and the graphics card unit is the hot end, and the end close to the endothermic plate is the cold end.

[0016] Preferably, a plurality of heat dissipation holes are formed in the side wall of the housing. A second fan unit is arranged on one side of the plurality of heat dissipation holes. The second fan unit is fixedly installed on the side wall of the housing. A dustproof net is arranged on the top of the housing.

[0017] The beneficial effects of the present invention are as follows: 1. For an emergency heat dissipation device of a server according to the present invention, through the collection component, when air flocs are affected by air flow and receive an upward moving force, they will move upward along the bottom side of the filter screen. Eventually, the air flocs will enter the interior of the dust inlet chamber through the dust inlet bin, thus no longer adhering to the bottom surface of the filter screen, achieving the effect that the bottom of the filter screen always remains unobstructed, reducing the resistance caused by the accumulation of air flocs, and enabling air to enter the interior of the housing more effectively for heat dissipation.

[0018] 2. For an emergency heat dissipation device of a server according to the present invention, the filter screen is driven to vibrate through the vibration component. During the vibration process of the filter screen, the fine dust in the screen holes will be discharged, thereby processing the filter screen and avoiding the reduction of wind force caused by dust clogging the filter screen, which is the reason for the excessive temperature inside the host.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] As Figures 1 to 8 shown, the present invention provides a technical solution: a server emergency heat dissipation device, including a housing 1, a motherboard unit 2 and a graphics card unit 3 are fixedly installed inside the housing 1, a first fan unit 4 is arranged below the graphics card unit 3, the first fan unit 4 is fixedly installed on the inner wall of the housing 1, a base 5 is fixedly installed at the bottom of the housing 1, a filter screen 6 is symmetrically and fixedly connected between the two bases 5, a cabinet door 24 is arranged on one side of the housing 1, a collection component is arranged between the two filter screens 6, the collection component is used for collecting the dust intercepted by the filter screen 6, and a vibration component for driving the filter screen 6 to remove dust is arranged outside the filter screen 6.

[0024] During operation: The motherboard unit 2 and the graphics card unit 3 are fixedly installed at the set positions inside the housing 1. When the server is operating, since the motherboard unit 2 and the graphics card unit 3 will be driven, their surface temperatures will gradually increase, and at the same time, the overall temperature inside the housing 1 will also increase. And while the server is operating, the blades inside each first fan unit 4 also rotate. When the blades rotate, they will generate an air flow, which can attract the cold air at the bottom of the housing 1 into the interior of the housing 1. The cold air will flow upward inside the housing 1. During the flow of the cold air, it will pass through the surfaces of the graphics card unit 3 and the motherboard unit 2, thereby taking away the heat dissipated from the surfaces of the graphics card unit 3 and the motherboard unit 2 due to driving, so as to achieve the effect of heat dissipation and temperature reduction. And when the cold air enters the interior of the housing 1 from the bottom of the housing 1, it will first pass through the filter screen 6. The filter screen 6 can intercept fine dust and larger flocs in the air, preventing the dust from adhering to the blades of the first fan unit 4 when it enters the interior of the housing 1. If these impurities accumulate on the blades for a long time, it will cause the blades to be blocked, the rotation of the blades to be hindered or stopped, resulting in a reduction in the efficiency of heat dissipation. The fine dust enters the pores of the filter screen 6 for interception, and the larger flocs cannot enter the pores and can be collected by the collection component, preventing the larger flocs from adhering to the bottom of the filter screen 6 under the action of wind for a long time, thereby affecting the flow of wind into the interior of the housing 1. Both the fine dust and the larger flocs are processed, so that the bottom side of the filter screen 6 always remains unobstructed, reducing the resistance caused by dust accumulation, and the air can enter the interior of the housing 1 more effectively, taking away the heat generated by the internal hardware of the server, thereby maintaining the stable operation of the server. The vibration component drives the filter screen 6 to vibrate to process the fine dust in its pores, reducing the problem that the fine dust accumulates too much and blocks the filter screen 6, resulting in wind resistance.

[0025] As Figures 5 to 6As shown in the figure, the dust collection component includes a dust inlet chamber 7, which is fixedly installed above and between two filter screens 6. A dust inlet bin 8 is fixedly connected to the bottom of the dust inlet chamber 7, and the dust inlet bin 8 is located below the bottom side of the filter screen 6. Both of the two filter screens 6 are in an arc shape.

[0026] During operation: When the blades inside the first fan unit 4 rotate, an air flow is generated, causing the cold air at the bottom of the housing 1 to enter the interior of the housing 1 through the filter screen 6. Fine dust and air flocs will be intercepted by the filter screen 6. As the continuous cold air flows from bottom to top, the fine dust will enter the pores of the filter screen 6, while the larger air flocs will be forced to be adsorbed onto the bottom surface of the filter screen 6. At this time, since the filter screen 6 is in an arc shape, the air flocs will be affected by the air flow and receive an upward moving force, and move upward along the bottom side of the filter screen 6. Eventually, the air flocs will enter the interior of the dust inlet chamber 7 through the dust inlet bin 8, so that they are no longer adsorbed onto the bottom surface of the filter screen 6, achieving the effect that the bottom of the filter screen 6 always remains unobstructed, reducing the resistance caused by the accumulation of air flocs, and enabling the air to enter the interior of the housing 1 more effectively for heat dissipation.

[0027] As Figures 5 to 7 shown in the figure, the top of the dust inlet chamber 7 is in a closed state. A dust dropping box 9 is fixedly connected to the bottom of the dust inlet chamber 7. Both the top and the bottom of the dust dropping box 9 are open, and the side is in a slope state. A collection box 10 is arranged below the dust dropping box 9, and the width of the collection box 10 is the same as the width of the dust inlet chamber 7.

[0028] During operation: Since the top of the dust inlet chamber 7 is in a closed state, there is no air flow generated by the rotation of the blades at this position and the positions in the same vertical direction. When the air flocs enter the interior of the dust inlet chamber 7 through the dust inlet bin 8, since the flocs no longer receive an upward thrust of air here, they will naturally fall into the interior of the dust dropping box 9 and flow out from the bottom opening of the dust dropping box 9 along the bottom surface of the dust dropping box 9. The flocs flowing out enter the interior of the collection box 10 for collection. And since the width of the collection box 10 is the same as the width of the dust inlet chamber 7, the collection box 10 is not affected by the air flow, and the flocs will not be re-adsorbed onto the filter screen 6 along with the air again after entering the interior of the collection box 10.

[0029] As Figures 3 to 4As shown, two base plates 15 are fixedly connected to the bottom of the housing 1, and both of the two base plates 15 are fixedly connected between the two bases 5. Two filter screens 6 are located between the two base plates 15. The vibration assembly includes a plurality of hinge members 19. The shaft rods of every two hinge members 19 are respectively fixedly connected to both ends of one side of the two filter screens 6. A plurality of extrusion blocks 18 are arranged above the other side of each of the filter screens 6. A rotating rod 17 is fixedly connected between the plurality of extrusion blocks 18 on each side. The rotating rods 17 are respectively rotatably connected to one of the base plates 15. One end of one of the rotating rods 17 is fixedly connected to a motor 16, and the motor 16 is fixedly installed on the top of the base plate 15. One end of each of the two rotating rods 17 is fixedly connected to a transmission ring 20, and a transmission belt 21 is drivingly connected between the two transmission rings 20. Side connection plates 23 are symmetrically and fixedly connected to the side surface of the dust collection box 9, and an angle spring 22 is fixedly connected between the bottom of the filter screen 6 and the side connection plates 23.

[0030] During operation: When the host detects that the internal temperature is higher than the threshold value, the motor 16 is started at this time. Its output shaft will drive the rotating rod 17 to rotate. When the rotating rod 17 rotates, it will drive the extrusion block 18 to rotate. When the extrusion block 18 rotates, it will continuously squeeze the other side of the filter screen 6, forcing the filter screen 6 to rotate downward in a hinged manner with the shaft rod of the hinge member 19 as the axis. And while the filter screen 6 rotates in a hinged manner, it will squeeze the angle spring 22 to cause it to deform. And when the extrusion block 18 rotates one circle, under the reaction force of the elastic force of the angle spring 22, the filter screen 6 rotates in a hinged manner and returns to its original position, thereby realizing the effect of making the filter screen 6 vibrate. During the vibration process of the filter screen 6, the fine dust in the sieve holes will be discharged, thereby processing the filter screen 6 and avoiding the reduction of wind force caused by dust clogging the filter screen 6 due to excessive internal temperature of the host.

[0031] As Figure 8 As shown, heat conduction tubes 11 are fixedly connected to the surfaces of the main board unit 2 and the graphics card unit 3. An endothermic plate 12 is fixedly installed on the inner wall of the housing 1. One end of each of the two heat conduction tubes 11 away from the main board unit 2 and the graphics card unit 3 is fixedly connected to one side of the endothermic plate 12. The end of the heat conduction tube 11 close to the main board unit 2 and the graphics card unit 3 is the hot end, and the end close to the endothermic plate 12 is the cold end.

[0032] During operation: When the main board unit 2 and the graphics card unit 3 are driven, the heat generated on the surface will be transferred to the hot end of the heat conduction tube 11 connected thereto. The heat received by the hot end of the heat conduction tube 11 will be transferred along the pipeline to the cold end, and the heat on the cold end will be transferred to the endothermic plate 12, further reducing the temperature on the surfaces of the main board unit 2 and the graphics card unit 3. Through the combined heat dissipation between the heat conduction tube 11 and the endothermic plate 12, the pressure of heat dissipation through the fan unit one 4 is reduced, and the heat dissipation effect is improved.

[0033] AsFigures 1 to 2 As shown, a plurality of heat dissipation holes 13 are provided on the side wall of the housing 1. One side of the plurality of heat dissipation holes 13 is provided with a second fan unit 14. The second fan unit 14 is fixedly installed on the side wall of the housing 1. A dust-proof net 25 is provided on the top of the housing 1.

[0034] During operation: When the server is operating, the respective blades of the second fan unit 14 will also rotate. When the blades rotate, part of the heat inside the housing 1 can be dissipated to the outside of the housing 1 through the heat dissipation holes 13, thereby further improving the overall temperature inside the housing 1 and enhancing the heat dissipation effect. The dust-proof net 25 prevents dust from entering from the top of the housing 1 and also increases the permeability of the entire housing 1.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
