Description

Technical Field

[0001] This application relates to the field of server heat dissipation technology, and in particular to a heat dissipation system, heat dissipation method, and computer room. Background Technology

[0002] Currently, with the development of internet technology, people have connected network communication and big data through network data. To better store network data, the use of servers is essential. As we all know, servers are generally installed and deployed in data centers. During server operation, servers generate a large amount of heat. Since a data center is a closed space, this heat cannot dissipate naturally and requires auxiliary technologies for heat dissipation.

[0003] Current technology typically employs air conditioning in the server room to blow cool air, which circulates and removes heat generated by the servers, thus cooling the room. However, due to the unprecedented development of big data, the amount of data to be stored and the capacity of servers are increasing, leading to a greater number of servers required. This makes the aforementioned cooling method insufficient to meet the server's cooling requirements, resulting in heat not being dissipated in time, high temperatures within the server room, and impaired server operation, ultimately preventing the servers from operating in a suitable environment.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are presented in the various embodiments of this application to facilitate a better understanding of the application.

The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0045] Reference Figure 1 , Figure 3As shown in the figure, this application embodiment provides a heat dissipation system 2, which includes an underground heat dissipation unit 21; the underground heat dissipation unit 21 includes a basement 211 located below the computer room 1, and a mesh panel 212 is provided between the basement 211 and the computer room 1, the mesh panel 212 being used to connect the basement 211 and the computer room 1; the basement 211 is provided with a condensing component for cooling the air in the basement 211; a first fan box 4 is provided on the side of the horizontal ground at the computer room 1, the first fan box 4 being used to discharge the air cooled by the condensing component into the computer room 1 through the mesh panel 212 to cool the computer room 1.

[0046] like Figure 1 , Figure 3 As shown, in one example, the computer room 1 is rectangular and built on a horizontal surface made of cement. The basement 211 is built at the bottom of the horizontal surface, constructed of reinforced concrete, and is located directly below the computer room 1. A stainless steel mesh panel 212 is bolted to the horizontal surface and is located between the basement 211 and the computer room 1, serving to connect the two spaces.

[0047] A condenser assembly is installed in basement 211 to cool the air in basement 211. Four first fan boxes 4 are installed, each bolted to the four sides of the server room 1 on a horizontal surface. The exhaust vents of the first fan boxes 4 are connected to the air inlets of basement 211, allowing the air cooled by the condenser assembly to be discharged into server room 1 through mesh panels 212 to cool the server room 1. Server room 1 includes, but is not limited to, a server room 1. Besides a rectangular shape, server room 1 can be flexibly configured as needed.

[0048] The above setup, by combining the basement 211 below the computer room 1, the mesh panel 212 between the basement 211 and the computer room 1, the condensation components in the basement 211, and the first fan box 4, cools down the computer room 1. This allows the heat in the computer room 1 to be removed in a timely manner, thereby preventing the temperature inside the computer room 1 from becoming too high and affecting the normal and effective operation of the server.

[0049] Reference Figure 1 As shown, in some embodiments, the condensation assembly includes condenser pipes 213 disposed inside the basement 211 and near its four sides, the condenser pipes 213 containing refrigerant; a condenser 3 is disposed on the horizontal ground at a position on the side of the machine room 1, the condenser 3 being connected to the condenser pipes 213 for cooling the refrigerant in the condenser pipes 213; so that after the first fan box 4 draws outside air into the condenser pipes 213, the air in the basement 211 is cooled through the condenser pipes 213.

[0050] like Figure 1 As shown, in one example, the condensing assembly includes multiple condenser pipes 213, which are evenly laid inside the basement 211 near its four sides, and each condenser pipe 213 is filled with refrigerant. Four condensers 3 are provided, each bolted to the four corners of the machine room 1 on the horizontal ground. A circulation pump is installed on each condenser 3, connected to the condenser pipes 213, to cool the refrigerant inside the condenser pipes 213, so that after the first fan box 4 draws outside air into the condenser pipes 213, the air inside the basement 211 can be cooled through the condenser pipes 213. Besides this, within the aforementioned spirit and principles, other possible methods can be used for the number, installation location, and installation method of the condensers 3.

[0051] The above setup, through the combination of multiple condenser pipes 213, the refrigerant inside the condenser pipes 213, and the condenser 3 located on the side of the machine room 1 on the horizontal ground, achieves the effect of cooling the air in the basement 211, thereby achieving the effect of cooling the air in the machine room 1.

[0052] Reference Figure 2 , Figure 3 As shown, in some embodiments, the heat dissipation system 2 further includes a ground heat dissipation unit 22, which is used to exhaust hot air in the computer room 1 to the outside of the computer room 1 to cool the computer room 1; a server chassis 5 is provided in the computer room 1, and several racks 6 are provided in the server chassis 5, which are all used to store server components 61; an outer shell 7 is provided on the outer periphery of the server chassis 5, and the ground heat dissipation unit 22 includes a second fan box 221 provided in the outer shell 7, which is used to absorb the heat generated by the server components and exhaust it to the outside of the computer room 1 to cool the computer room 1.

[0053] like Figure 2 , Figure 3 As shown, in one example, the heat dissipation system 2 also includes a ground-level heat dissipation unit 22 for exhausting hot air from the computer room 1 to the outside of the computer room 1 to cool the computer room 1. Several server chassis 5 are provided, all of which are installed inside the computer room 1. The server chassis 5 includes a chassis base plate 51 located on the bottom surface of the computer room 1 and a chassis top plate 52 located directly above the chassis base plate 51. Both the chassis base plate 51 and the chassis top plate 52 are rectangular. The upper end surface of the chassis top plate 52 has a cable hole 521 along its length and near the edge. The upper end surface of the chassis top plate 52 has a wiring groove 522 welded along its length. The wiring groove 522 and the cable hole 521 are spaced apart for placing the connection wires of the server components 61.

[0054] Continue to refer to Figure 3, a support rod 53 is arranged between the chassis bottom plate 51 and the chassis top plate 52. There are four support rods 53, and the four support rods 53 are located at the four corners of the chassis bottom plate 51. The lower end of each support rod 53 is welded to the upper surface of the chassis bottom plate 51, and the upper end is welded to the lower surface of the chassis top plate 52. A number of racks 6 are arranged in the server chassis 5 and are fixedly connected to the chassis bottom plate 51 at intervals along the length direction of the server chassis 5 by bolts. A plurality of server components 61 are fixedly connected in the rack 6 by bolts.

[0055] The outer shell sleeve 7 is arranged in a "return" shape and is sleeved on the outer peripheral side of the server chassis 5. The above-ground heat dissipation unit 22 includes a second blower box 221. There are four second blower boxes 221, and the four second blower boxes 221 are respectively fixedly installed on the four side surfaces of the outer shell sleeve 7 by bolts, and are used to suck the heat generated by the server components 61 and discharge it outside the computer room 1 to cool the computer room 1.

[0056] With the above settings, through the arrangement of the second blower boxes 221 installed on the four side surfaces of the outer shell sleeve 7, the effect of sucking the heat generated by the server components 61 and discharging it outside the computer room 1 to cool the computer room 1 is achieved, further ensuring the normal and effective operation of the server.

[0057] Refer to Figure 2 、 Figure 3 As shown in

[0058] In some embodiments, the above-ground heat dissipation unit 22 can also be connected to the underground heat dissipation unit 21 and is used to suck the cold air of the underground heat dissipation unit 21 into the computer room 1 to cool the computer room 1; a lifting groove communicating with the basement 211 is provided at the position of the horizontal ground on the outer peripheral side of the server chassis 5; a hydraulic cylinder 71 that can make the outer shell sleeve 7 lift along the height direction of the rack 6 is provided on the bottom surface of the outer shell sleeve 7; the second blower box 221 can suck the cold air of the basement 211 into the computer room 1 to cool the computer room 1 by lifting and reversing. Figure 2 、 Figure 3As shown, in one example, the above-ground heat dissipation unit 22 can also be connected to the underground heat dissipation unit 21 to draw cold air from the underground heat dissipation unit 21 into the machine room 1 to cool it down. The lifting trough is located between the machine room 1 and the basement 211 at the horizontal ground level, and both the lifting trough and the outer casing 7 are arranged in a "U" shape. Four hydraulic cylinders 71 are provided, each located at one of the four corners of the outer casing 7. The bottom of each hydraulic cylinder 71 is bolted to the bottom of the basement 211, and the top is bolted to the bottom of the outer casing 7. A hydraulic oil pump and a hydraulic oil tank, which work in conjunction with the hydraulic cylinders 71, are installed in the basement 211. The hydraulic oil pump is connected to the hydraulic oil tank and the hydraulic cylinders 71 via hydraulic oil pipes. Because the hydraulic cylinders 71 can raise and lower the outer casing 7 along the height of the frame 6 through the lifting trough, the second fan box 221 can draw cold air from the basement 211 into the machine room 1 to cool it down by reversing its lifting motion.

[0059] The above-mentioned setup combines the above-ground heat dissipation unit 22 and the underground heat dissipation unit 21. Through the cooperation of the hydraulic cylinder 71 and the second fan box 221, the cold air from the basement 211 is drawn into the machine room 1 to cool the machine room 1, thereby further ensuring the cooling effect of the machine room 1.

[0060] Reference Figure 1 , Figure 3 As shown, in some embodiments, the ground heat dissipation unit 22 further includes a third fan box 222, which is disposed on the top surface of the computer room 1 and is used to draw in hot air from the computer room 1 and exhaust it outside the computer room 1 to cool the computer room 1.

[0061] like Figure 1 , Figure 3 As shown, in one example, the ground-level heat dissipation unit 22 also includes a third fan box 222. The third fan box 222 is bolted to the upper surface of the machine room 1 and is used to draw in hot air from the machine room 1 and exhaust it outside the machine room 1 to cool it down. It should be noted that the first fan box 4, the second fan box 221, and the third fan box 222 are all equipped with dust filters to prevent dust from entering and affecting the working efficiency of the first fan box 4, the second fan box 221, and the third fan box 222.

[0062] The above-mentioned configuration, specifically the third fan box 222, can draw in hot air from the computer room 1 and exhaust it outside the computer room 1 to cool it down, ensuring that the server can always operate in a good environment.

[0063] It should also be noted that the above-mentioned underground heat dissipation unit 21 and above-ground heat dissipation unit 22 are the preferred embodiments provided in this application. In addition to this preferred embodiment, only one of the underground heat dissipation unit 21 and above-ground heat dissipation unit 22 may be used, or heat dissipation units may be used in other locations. This application will not list them all. As long as they are within the spirit and principles of the embodiments of this application, they are all within the protection scope of this application.

[0064] In combination with the above Figure 1-3 as well as Figure 4 As shown in the embodiment of this application, a heat dissipation method is also provided, which can be applied to the heat dissipation system 2 described above; the method includes:

[0065] Step S501: Monitor the temperature value of temperature sensor 62 in real time.

[0066] Here, the aforementioned heat dissipation system 2 also includes a temperature sensor 62 bolted to the rack 6 and a controller 8 located in the server room 1; the temperature sensor 62 is located on the upper surface of the server component 61 and can monitor the temperature value of the server component 61 in real time. The controller 8 is located between two adjacent server chassis 5 and is connected to the temperature sensor 62, the hydraulic oil pump, the condenser 3, the first fan box 4, the second fan box 221, and the third fan box 222, respectively.

[0067] Specifically, temperature sensor 62 senses the temperature value of server component 61 in real time, and controller 8 monitors the temperature value of temperature sensor 62 in real time.

[0068] Step S503: Determine the current temperature level of computer room 1 based on the monitored temperature value, and perform heat dissipation operation on computer room 1 based on the temperature level.

[0069] Specifically, the controller 8 determines the current temperature level of the computer room 1 based on the monitored temperature values, and performs heat dissipation operations on the server components 61 in the computer room 1 based on the temperature level.

[0070] The above method involves real-time monitoring of the temperature value of the temperature sensor 62 to determine the current temperature level of the computer room 1, and then performing heat dissipation operations on the computer room 1 based on the temperature level to ensure the normal and effective operation of the server.

[0071] In one embodiment, the method includes: when the current temperature value of the computer room 1 is detected to be at a first temperature level, controlling the first fan box 4 to operate, drawing cold air from the basement 211 into the computer room 1 through the mesh plate 212; controlling the second fan box 221 to operate, exhausting hot air from the server chassis 5 into the computer room 1; and controlling the third fan box 222 to operate, exhausting hot air from the computer room 1 to the outside of the computer room 1 to cool the computer room 1.

[0072] The temperature levels include the first temperature level.

[0073] Specifically, when the controller 8 detects that the current temperature value of the computer room 1 is at the first temperature level, it controls the first fan box 4 to be powered on, drawing the cold air in the basement 211 onto the mesh plate 212, and discharging it into the computer room 1 through the mesh holes on the mesh plate 212; the controller 8 controls the second fan box 221 to be powered on, drawing the hot air from the server chassis 5 into the computer room 1; the controller 8 controls the third fan box 222 to be powered on, discharging the hot air in the computer room 1 to the outside of the computer room 1 to achieve the effect of cooling the computer room 1.

[0074] The above method, when the current temperature value of the computer room 1 is detected to be at the first temperature level, controls the first fan box 4 and the second fan box 221 to work in order to cool down the computer room 1, thereby achieving the effect of heat dissipation while reducing heat dissipation costs.

[0075] In one embodiment, the method further includes: when the current temperature value of the computer room 1 is detected to be at the second temperature level, controlling the first fan box 4, the second fan box 221 and the third fan box 222 to work while controlling the condenser 3 to work; controlling the condenser 3 to cool the refrigerant in the condenser pipe 213 installed in the basement 211 to cool the air in the basement 211, so as to use the first fan box 4 to draw the cold air in the basement 211 into the computer room 1 through the mesh plate 212 to cool the computer room 1.

[0076] The temperature levels also include a second temperature level, where the temperature is higher than that of the first temperature level.

[0077] Specifically, when the controller 8 detects that the current temperature of the computer room 1 is at the second temperature level, since the temperature at the second temperature level is higher than that at the first temperature level, the controller 8 can simultaneously control the operation of the first fan box 4, the second fan box 221, and the third fan box 222, and also control the condenser 3 to be powered on. The controller 8 controls the condenser 3 to cool the refrigerant in the condenser pipe 213 located in the basement 211. The fan in the first fan box 4 draws outside air onto the condenser pipe 213, where it is cooled, and then discharged through the through-holes on the mesh plate 212 to cool the computer room 1.

[0078] The above method: When the current temperature value of the computer room 1 is detected to be at the second temperature level, since the temperature of the second temperature level is higher than that of the first temperature level, controlling the first fan box 4 and the second fan box 221 to work alone is not enough to meet the heat dissipation effect. It is also necessary to control the condenser 3 to work at the same time in order to cool down the computer room 1 more quickly.

[0079] In one embodiment, the method further includes: when the current temperature value of the computer room 1 is detected to be at the third temperature level, controlling the first fan box 4, the second fan box 221, the third fan box 222 and the condenser 3 to work, while also controlling the hydraulic cylinder 71 to work; controlling the hydraulic cylinder 71 to drive the outer casing 7 to move up and down between the computer room 1 and the basement 211, and drawing cold air from the basement 211 into the computer room 1 through the second fan box 221 to cool the computer room 1.

[0080] The temperature levels also include a third temperature level, where the temperature is higher than that of the second temperature level.

[0081] Specifically, when the controller 8 detects that the current temperature of the computer room 1 is at the third temperature level, since the temperature of the third temperature level is higher than that of the second temperature level, the controller 8 can simultaneously control the operation of the first fan box 4, the second fan box 221, the third fan box 222, and the condenser 3, and also control the hydraulic cylinder 71 to be energized. The controller 8 controls the hydraulic cylinder 71 to descend slowly, and the outer casing 7 descends slowly accordingly, and the second fan box 221 also descends slowly, so that the second fan box 221 is located in the basement 211. By controlling the second fan box 221 to rise and reverse, the cold air in the basement 211 can be drawn into the computer room 1 through the mesh plate 212 to cool the computer room 1, improve the air circulation in the computer room 1, and achieve a rapid cooling effect.

[0082] The above method: When the current temperature value of the computer room 1 is detected to be at the third temperature level, since the temperature of the third temperature level is higher than that of the second temperature level, controlling only the first fan box 4, the second fan box 221 and the condenser 3 cannot achieve a good cooling effect. Therefore, the third fan box 222 can also be controlled to ensure that the server is always in a good operating environment.

[0083] The heat dissipation system 2 provided in this application embodiment can be applied to various heat dissipation scenarios to prevent excessively high temperatures in enclosed spaces. For example, the heat dissipation system 2 can be installed in: computer rooms containing communication equipment, factories containing medical equipment, and laboratories containing power supply equipment, etc. This application does not list them all. As long as they are within the spirit and principles described above in the embodiments of this application, they all fall within the protection scope of this application.

[0084] Taking a computer room 1 containing communication equipment as an example, this application embodiment also provides a computer room, referring to... Figure 1 , Figure 5The system includes the aforementioned heat dissipation system 2 and an insulation wall 11. The insulation wall 11 is rectangularly arranged on a horizontal surface and is used for heat preservation. An inner cover 12 is provided inside the insulation wall 11. The inner cover 12 is made of stainless steel plate 121 and square tube 122 welded together. A cavity 13 for placing refrigerant is provided between the inner cover 12 and the insulation wall 11. A condenser 3 is installed on the outside of the insulation wall 11 at its four corners. The condenser 3 is connected to the cavity 13 through a connecting pipe 14. After the condenser 3 cools, the refrigerant flows back into the cavity 13 for cooling, so as to facilitate the cooling of the computer room 1 by using the inner cover 12.

[0085] Since the computer room 1 itself can also achieve heat dissipation, when the controller 8 detects that the current temperature value of the computer room 1 is at a certain level, such as the third temperature level, the controller 8 controls the condenser 3 to work. The condenser 3 cools the refrigerant in the cavity 13 between the inner cover 12 and the insulation wall 11, so that the stainless steel plate 121 on the inner wall of the inner cover 12 cools the air in the computer room 1, thereby accelerating the heat dissipation effect.

[0086] The above-mentioned setup, along with the fact that the computer room 1 itself has a heat dissipation function, provides greater assurance for accelerating the heat dissipation of the air inside the computer room 1, thereby preventing the temperature inside the computer room 1 from becoming too high and affecting the normal and effective operation of the server.

[0087] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this application and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this application should be included within the protection scope of this application. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
