Description

Technical Field

[0001] The invention belongs to the technical field of heat dissipation in a data center computer room, and in particular relates to a heat dissipation device in a data center computer room. Background Art

[0002] A data center room is a place dedicated to storing and managing large-scale servers, network equipment, and storage devices. It provides a stable and reliable environment and infrastructure to ensure data security, availability, and efficiency. Since a large number of electronic components are stored in the room, the heat dissipation of electronic components becomes particularly important. Currently, data center rooms are equipped with special heat dissipation devices to dissipate the heat of network equipment.

[0003] For example, the utility model patent with announcement number CN212753074U discloses a heat dissipation device for a data center computer room. The device cools down after passing through a water evaporation curtain, effectively reducing the temperature in the computer room. At the same time, water can evaporate, and the evaporation of water absorbs a large amount of heat, which further cools the computer room. The exhaust system continuously exhausts air to dissipate heat and cool down the computer room, while ensuring that ventilation and humidity are maintained in the computer room. The water cooling system enables the utility model to maintain a certain water circulation and reduce energy consumption.

[0004] However, the above patent still has some problems in heat dissipation: when using a data center room in some hot areas, the network equipment is more likely to generate heat due to the influence of the external environment, and when the network equipment in the data center room is used, the air rises due to the heat, so the air near the network equipment will flow upward due to the heat, which will cause the temperature of the upper part of the network equipment to be higher. Although the heat dissipation device used in the above patent can circulate the heat, it cannot uniformly dissipate the heat of the network equipment as a whole. Therefore, the heat dissipation effect needs to be further improved. In this regard, a heat dissipation device for a data center room is proposed, which can evenly convert the heat generated by the network equipment into cold air, and use the cold air to evenly dissipate the heat of the network equipment from bottom to top. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a heat dissipation device for a data center computer room, which solves the problem that the heat dissipation device in the prior art can circulate heat but cannot uniformly dissipate heat for the entire network equipment.

[0006] The objective of the present invention can be achieved through the following technical solutions: A heat dissipation device for a data center computer room, comprising a box connected to a network device and a gas cooling assembly arranged on the box, wherein the box and the gas cooling assembly together constitute a gas channel for uniformly dissipating heat from the network device; the gas cooling assembly comprises a blower unit arranged on the top of the network device, a gas cooling unit, and a speed reduction unit for multi-stage speed reduction of the gas, wherein the speed reduction unit runs through the gas cooling unit, the gas cooling unit is used to cool the gas in the speed reduction unit, and the two ends of the speed reduction unit are respectively connected to the blower unit and the bottom of the network device, and the gas at the top of the network device enters the speed reduction unit through the blower unit, so that the gas enters the bottom of the network device after being uniformly cooled.

[0007] As a further solution of the present invention, the network device is connected to the box through two supporting heat sinks, which are respectively located at the bottom and top of the network device, and the blower of the blower unit is connected to the supporting heat sink at the top of the network device.

[0008] As a further solution of the present invention, the bottom and top of the box body are provided with gas containing chambers, and the gas containing chambers at the bottom and top of the box body are respectively connected to the supporting heat sink at the bottom of the network device and the blower of the blower part.

[0009] As a further solution of the present invention, the supporting heat sink is a rectangular structure, a plurality of fans are arranged on the side walls of the supporting heat sink, and a plurality of air holes for gas flow are arranged on one of the bottom wall or the top wall.

[0010] As a further solution of the present invention, the gas cooling part includes a cooling box arranged on the side wall of the box body, and an air inlet pipe and an air outlet pipe are respectively provided at both ends of the cooling box, and the air inlet pipe and the air outlet pipe are respectively connected to the gas containing chambers at the top and bottom of the box body.

[0011] As a further solution of the present invention, the number of the air inlet pipes and the air outlet pipes is greater than or equal to three.

[0012] As a further solution of the present invention, the speed reduction portion is a concave-convex tube, and the number of concave and convex portions of the concave-convex tube is greater than or equal to three.

[0013] As a further solution of the present invention, the connection between two adjacent concave-convex tubes is an arc-shaped structure.

[0014] As a further solution of the present invention, a plurality of shock absorbing members for reducing the vibration force transmitted to the network device are arranged inside the supporting heat sink, and the plurality of shock absorbing members are evenly distributed inside the supporting heat sink.

[0015] The beneficial effects of the present invention are: By installing a blower unit on the top of the network equipment, when the network equipment generates heat, the air near the network equipment will flow upward due to the heat, which will cause the temperature of the upper part of the network equipment to be higher. The hot air on the upper part of the network equipment is discharged to the deceleration unit through the blower unit, and at the same time, the gas in the deceleration unit is cooled by the gas cooling unit. The deceleration unit performs multi-stage deceleration on the gas, so that all the gas flowing through the gas cooling unit can be evenly cooled, and then discharged to the bottom of the network equipment through the gas cooling unit. Since the subsequent cold gas continuously squeezes the gas at the bottom of the network equipment, the cold air can be gradually moved from the bottom of the network equipment to the top. Not only can the heat be dissipated in a targeted manner according to the specific heating situation of the network equipment, but the heat can also be evenly dissipated for the entire network equipment, which solves the problem that the heat dissipation device in the prior art can circulate the heat but cannot evenly dissipate the heat for the entire network equipment.

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-6The present embodiment provides a heat dissipation device for a computer room in a data center, comprising a box body 1 connected to a network device 4 and a gas cooling assembly 2 arranged on the box body 1, wherein the box body 1 and the gas cooling assembly 2 together form a gas channel for uniformly dissipating heat to the network device 4; when the network device 4 is placed in the box body 1, a gap is left between the box body 1 and the side wall, which can better dissipate heat on the one hand and prevent the box body 1 from interfering with the operation of the network device 4 on the other hand, wherein the gas cooling assembly 2 comprises a blower part 21 arranged on the top of the network device 4, a gas cooling part 22, and a speed reduction part 23 for multi-stage speed reduction of the gas, wherein the speed reduction part 23 runs through the gas cooling part 22, and the gas cooling part 22 is used to cool the gas in the speed reduction part 23, and the two ends of the speed reduction part 23 are respectively connected to the blower part 21 and the bottom of the network device 4 The gas at the top of the network device 4 enters the deceleration part 23 through the blower part 21, so that the gas enters the bottom of the network device 4 after being evenly cooled. The blower part 21 here is a blower, but this blower needs to cooperate with the deceleration part 23. The deceleration part 23 performs multi-stage deceleration on the gas blown out by the blower, so that the gas can be evenly cooled when flowing through the gas cooling part 22, thereby improving the subsequent heat dissipation efficiency and making full use of resources at the same time, so as to achieve better circulation heat dissipation effect. Since the hot air at the top of the network device 4 needs to be transferred quickly, a blower is used. However, since the speed at which the blower discharges the gas is also relatively fast, the gas with a relatively fast speed cannot be guaranteed to be well cooled when passing through the gas cooling part 22. Therefore, the deceleration part 23 is used to perform multi-stage deceleration on the gas, so as to facilitate the even cooling of the gas.

[0021] At present, when dissipating heat, data center computer rooms mostly use air cooling or water cooling to achieve circulating heat dissipation and reduce energy consumption. However, there are still some problems when existing data center computer rooms use air cooling or water cooling for circulating heat dissipation. For example, when using a data center computer room in some hot areas, the network equipment 4 is more likely to generate heat due to the influence of the external environment, and when the network equipment 4 in the data center computer room is used, the air rises due to the heat, so the air near the network equipment 4 will flow upward due to the heat, which will cause the temperature of the upper part of the network equipment 4 to be higher. When the heat dissipation device used in the above patent dissipates heat in a circulating manner, the exhaust system draws air to dissipate the heat and cool the computer room, and the water cooling system circulates water to dissipate heat. However, this method belongs to uniform heat dissipation of the outside of the network equipment 4, and cannot dissipate heat in a targeted manner according to the specific heating situation of the network equipment 4. Therefore, the network equipment 4 cannot be evenly cooled as a whole, resulting in poor heat dissipation effect or waste of resources.

[0022] In order to solve this problem, in this embodiment, when used in a data center computer room in some hot areas, the heat dissipation effect needs to be better. For this reason, a blower unit 21 is installed on the top of the network device 4. When the network device 4 generates heat, the air near the network device 4 will flow upward due to the heat, which will cause the temperature of the upper part of the network device 4 to be higher. The hot air on the upper part of the network device 4 is discharged to the deceleration unit 23 through the blower unit 21, and at the same time, the gas in the deceleration unit 23 is cooled by the gas cooling unit 22. The deceleration unit 23 performs multi-stage deceleration on the gas, so that all the gas flowing through the gas cooling unit 22 can be evenly cooled, and then discharged to the bottom of the network device 4 through the gas cooling unit 22. Since the subsequent cold gas continuously squeezes the gas at the bottom of the network device 4, the cold air can be gradually moved from the bottom of the network device 4 to the top. Not only can the heat be dissipated in a targeted manner according to the specific heating situation of the network device 4, but the network device 4 can also be evenly dissipated as a whole, which solves the problem that the heat dissipation device in the prior art can circulate the heat but cannot evenly dissipate the heat of the network device 4 as a whole.

[0023] In order to ensure that there is enough gap between the top and bottom of the network device 4 and the box body 1 to facilitate the circulation of gas, so as to further increase the heat dissipation effect, in one embodiment, the network device 4 is connected to the box body 1 through two supporting heat sinks 3, and the two supporting heat sinks 3 are respectively located at the bottom and top of the network device 4. The blower of the blower unit 21 is communicated with the supporting heat sink 3 on the top of the network device 4. Through the supporting heat sink 3, not only can the network device 4 be supported, and the box body 1 can stably fix the network device 4 in the box body 1, but also a gap can be left between the top and bottom of the network device 4 and the box body 1 to facilitate the circulation of gas, thereby further increasing the heat dissipation effect.

[0024] In addition, when the blower transports the hot air at the top of the network device 4 to the deceleration part 23, in order to achieve a better deceleration effect when the gas flows through the deceleration part 23, it is necessary to reduce the speed of the gas before entering the deceleration part 23 in advance. In this regard, in one embodiment, the bottom and top of the box body 1 are provided with a gas containing chamber, and the gas containing chambers at the bottom and top of the box body 1 are respectively connected to the support heat sink 3 at the bottom of the network device 4 and the blower of the blower part 21. On the one hand, the gas containing chamber can block the speed of the gas transported by the blower. On the other hand, the gas containing chamber can also concentrate the hot air inside to prevent the hot air from reflux due to the mutual squeezing of the hot air when the blower transports the hot air when there is a lot of hot air, thereby improving the efficiency of hot air transportation and further improving the cooling effect.

[0025] Furthermore, since the gas flows slowly, when the gas enters the supporting heat sink 3, it takes a certain amount of time to get out of the supporting heat sink 3. In order to speed up the circulation of the gas in the supporting heat sink 3 and speed up the overall heat dissipation cycle, in one embodiment, the supporting heat sink 3 is a rectangular structure, and a plurality of fans 7 are arranged on the side walls of the supporting heat sink 3, and a plurality of air holes 9 for gas flow are arranged on one of the bottom wall or the top wall. The gas circulation in the supporting heat sink 3 can be accelerated by the plurality of fans 7. Under the action of the fans 7, the gas in the supporting heat sink 3 is driven to be discharged through the air holes 9. The supporting heat sink 3 here is a rectangular box, and a plurality of fans 7 are arranged on the four side walls of the rectangular box, and a plurality of air holes 9 are arranged on one of the top wall or the bottom wall. The supporting heat sink 3 located at the top of the network device 4 has a plurality of air holes 9 on its bottom wall, and a blower is arranged on the top wall, and one end of the blower passes through the top wall of the supporting heat sink 3; the supporting heat sink 3 located at the bottom of the network device 4 has a plurality of air holes 9 on its top wall, such as Figure 4 shown.

[0026] In order to convert the gas output by the blower into cold air and then enter the network device 4 to cool the network device 4, in one embodiment, the gas cooling unit 22 includes a cooling box arranged on the side wall of the box body 1, and an air inlet pipe 24 and an air outlet pipe 25 are respectively provided at both ends of the cooling box. The air inlet pipe 24 and the air outlet pipe 25 are respectively connected to the gas containing chambers at the top and bottom of the box body 1. The number of the air inlet pipe 24 and the air outlet pipe 25 is greater than or equal to three. The purpose of requiring the number of the air inlet pipe 24 and the air outlet pipe 25 to be greater than or equal to three is, on the one hand, to make the gas pass through the gas cooling unit 22 through diversion so that the temperature can be more evenly reduced, and on the other hand, By diverting the flow, the speed of the gas passing through the gas cooling part 22 is slowed down, which can achieve better cooling; therefore, the number of the air inlet pipe 24 and the air outlet pipe 25 here can be three, but if there are three, they need to be located on both sides and the middle of the cooling box respectively, so as to be evenly distributed. If there are four or more, they also need to be evenly distributed, and the heat dissipation effect will be better. The upper part of the rear of the cooling box is fixedly connected with a liquid inlet 5, and the lower part of the rear of the cooling box is fixedly connected with a liquid drain 6; through the action of the liquid inlet 5 and the liquid drain 6, the coolant inside the cooling box can be replaced through the external circulation system, thereby ensuring the heat dissipation of the network device 4 inside the box body 1.

[0027] It is worth mentioning that if the gas speed output by the blower is slow, the hot air above the network device 4 cannot be quickly sent out. If the gas speed output is too fast, it cannot be guaranteed that the gas can be evenly cooled when passing through the gas cooling part 22. In this regard, in one embodiment, the speed reduction part 23 is a concave-convex tube, and the structure of the concave-convex tube is as follows: Figure 4As shown, the connection between two adjacent concave-convex tubes is an arc structure, which can facilitate gas circulation and reduce noise during gas circulation. In addition, the number of concave and convex parts of the concave-convex tube is greater than or equal to three. The limit on the number of concave and convex parts of the concave-convex tube here is to reduce the speed of gas circulation better through multiple concave and convex bends. Taking the front, middle and back three as an example, in order to achieve a better effect of reducing the speed of gas circulation, the minimum number is three, and it can also be four or more. In addition, it is particularly important that the number of concave and convex parts of the concave-convex tube here needs to match the power of the blower used. It is necessary to ensure that the gas transported by the blower can still circulate after passing through the concave-convex tube. The gas cannot be unable to circulate in the concave-convex tube due to the low power of the blower. Therefore, the concave-convex tube and the blower need to be designed in coordination with each other.

[0028] In addition, when the network device 4 is cooled, since the fan 7 and the blower will generate certain vibrations, in order to avoid damage to the network device 4 caused by vibration, in one embodiment, a plurality of shock absorbing members 8 for reducing the vibration force transmitted to the network device 4 are provided in the support heat sink 3, and the plurality of shock absorbing members 8 are evenly distributed in the support heat sink 3, and the shock absorbing member 8 includes a connecting column 1 81, the upper surface of the connecting column 1 81 is fixedly connected to the inner cavity of the supporting plate 1, the inner cavity of the connecting column 1 81 is clamped with a limiting block 83, the lower surface of the limiting block 83 is fixedly connected with a connecting column 2 82 and the connecting column 2 82 is located below the connecting column 1 81, and the lower surface of the connecting column 2 82 is fixedly connected to the upper surface of the supporting plate 2. The outer wall of the limiting block 83 is movably sleeved with a sealing rubber pad 842, and the upper and lower sides of the sealing rubber pad 842 are respectively fixedly connected to the opposite surfaces of the connecting column 1 81 and the connecting column 2 82, and the upper surface of the connecting column 2 82 is fixedly connected with two shock absorbers 85, and the two shock absorbers 85 are located at the front and rear sides of the limiting block 83, and the upper and lower sides of the two shock absorbers 85 are respectively fixedly connected to the opposite surfaces of the connecting column 1 81 and the connecting column 2 82, and through the action of the sealing rubber pad 842, the connecting column 1 81 and the connecting column 2 82 can be buffered, so that shock absorption protection is performed under the action of the shock absorber 85, thereby reducing the vibration caused by heat dissipation during use, thereby protecting the supported and fixed network equipment 4.

[0029] The working principle and use process of the present invention: By installing a blower unit 21 on the top of the network device 4, when the network device 4 generates heat, the air near the network device 4 will flow upward due to the heat, which will cause the temperature of the upper part of the network device 4 to be higher. The hot air on the upper part of the network device 4 will be discharged to the deceleration unit 23 through the blower unit 21, and at the same time, the gas in the deceleration unit 23 will be cooled by the gas cooling unit 22. The deceleration unit 23 performs multi-stage deceleration on the gas, so that all the gas flowing through the gas cooling unit 22 can be evenly cooled, and then discharged to the bottom of the network device 4 through the gas cooling unit 22. Since the subsequent cold gas continuously squeezes the gas at the bottom of the network device 4, the cold air can be gradually moved from the bottom of the network device 4 to the top. According to the specific heating situation of the network device 4, targeted heat dissipation can be performed, and the network device 4 as a whole can also be evenly cooled.
