Server

Abstract

The invention provides a server. The server comprises a substrate and two first fairing devices. Each first flow guide cover device comprises a first cover body and a first flow baffle. Each first cover body is provided with a first top plate, two first side plates and two first rail units. Each first top plate and the corresponding first side plate define a first air inlet, a first air outlet and a first flow channel area located between the first air inlet and the first air outlet. Each first flow baffle is provided with two first convex column units; by means of the design that the first protruding column unit of each first flow baffle can move relative to the first rail unit, one first flow baffle can be moved to the position where the corresponding first flow channel area is shielded, so that the overall flow resistance of the first cover body without the requirement for heat dissipation inside is increased; therefore, more airflow can enter the first air inlet of the other first cover body with the heat dissipation requirement and flow through the corresponding first flow channel area for heat dissipation, and the good heat dissipation efficiency is effectively ensured.

Description

Technical Field

[0001] The present invention relates to the technical field of electronic systems, and in particular to a server. Background Art

[0002] In recent years, with the rapid development and growth of servers, servers are often equipped with high-heat electronic components such as central processing units (CPUs), graphic display chip cards (GPUs), and riser cards, which can perform large data processing and high-speed data calculations. However, during the high-performance data processing and calculation process, heat energy will be generated inside the server and must be dissipated to avoid the risk of internal overheating leading to system instability, reduced processing speed, or crashes. It is now common to use an air duct to guide the internal heat dissipation airflow by using multiple guide channels of the air duct. However, the placement of heat-generating electronic components inside the server often has different configuration designs. It often happens that at least one guide channel in the air duct does not have a heat-generating electronic component that needs to be dissipated. However, since the flow resistance of the guide channel without heat-generating electronic components is smaller than that of the guide channel with heat-generating electronic components, a large amount of wind flow is easy to flow into the guide channel with smaller flow resistance, resulting in only a small amount of wind flow flowing through the guide channel with heat-generating electronic components and unable to effectively dissipate heat, and even causing the risk of overheating of the heat-generating electronic components. Furthermore, since the placement of heat-generating electronic components inside the server often has different configuration designs, a server system needs to be designed with a variety of different air guide cover styles to meet the needs of different internal configurations. This not only makes it impossible to effectively manage materials but also greatly increases production costs. The above problems deserve further careful study and discussion by practitioners to improve. Summary of the invention

[0003] Therefore, the purpose of the present invention is to provide a server with good heat dissipation efficiency and adjustable air flow.

[0009] Preferably, each second air deflector device also includes a second sealing unit arranged on each second cover body and located in each second flow channel area and adjacent to the second air outlet. Each second cover body also has a second combining frame corresponding to the second air outlet and connecting the second top plate and the second side plate.

Implementation

[0017] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0018] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The server of the present invention comprises a substrate 1 and two first air guide cover devices 2 arranged on the substrate 1.

[0019] Each first air deflector device 2 includes a first cover body 21 disposed on the substrate 1, and a first baffle plate 23 disposed on the first cover body 21. Each first cover body 21 has a first top plate 211, two first side plates 212 extending from two opposite sides of the first top plate 211 toward the substrate 1 and disposed on the substrate 1, and two first track units 22 respectively recessed in the inner sides of the first side plates 212. Each first top plate 211 and the first side plates 212 together define a first air inlet 213, a first air outlet 214, and a first flow channel area 215 located between the first air inlet 213 and the first air outlet 214. Each first baffle plate 23 is close to the first air outlet 214 and can be controlled to move to block the corresponding first flow channel area 215. Each first baffle plate 23 has two first boss units 231 located on two opposite sides and extending into the first track unit 22 respectively, and can move relative to the first track unit 22.

[0020] Each first track unit 22 has a first horizontal track 221 parallel to each first top plate 211, a first vertical track 223 perpendicular to and connected to the first horizontal track 221 and close to the corresponding first air outlet 214, and a first positioning slot module 224 close to the first air outlet 214. Each first horizontal track 221 has a first clamping slot 222 away from the first air outlet 214. Each first positioning slot module 224 has a first upper positioning slot 225 connected to the first horizontal track 221 and extending from the first horizontal track 221 to the direction of the first air outlet 214, and a first lower positioning slot 226 connected to the first vertical track 223 and extending from the first vertical track 223 to the direction of the first air outlet 214.

[0021] Each first boss unit 231 of each first baffle 23 has a first clamping boss 232 that can be adjusted to move between the first clamping groove 222, the first horizontal rail 221 and the first upper positioning groove 225, and a first limiting boss 233 that can be adjusted to move between the first vertical rail 223 and the first lower positioning groove 226.

[0022] When the first clamping protrusion 232 of the first protrusion unit 231 of any first baffle 23 is clamped into the first clamping groove 222 of the first track unit 22, at this time, the first baffle 23 does not block the corresponding first flow channel area 215; when the first clamping protrusion 232 of any first baffle 23 is clamped into the first upper positioning groove 225 of the first positioning groove module 224 and the first limiting protrusion 233 is clamped into the first lower positioning groove 226, at this time, the first baffle 23 blocks the corresponding first flow channel area 215. In particular, in this embodiment, one of the first side plates 212 of one of the first cover bodies 21 in the first air guide cover device 2 abuts against one of the first side plates 212 of another first cover body 21 and the first cover body 21 is combined into one body, and the first air inlets 213 are adjacent to each other and the first air outlets 214 are adjacent to each other, and the first cover body 21 is covered on the substrate 1 and located at the front side of the substrate 1. In simple terms, the first covers 21 are connected to each other as follows: Figure 1 In the embodiment shown, one of the first side plates 212 is used to abut against each other and form an integral body, but the present invention is not limited thereto. In addition, in the present embodiment, the first flow channel area 215 of the first cover body 21 of each first air guide cover device 2 can be used to accommodate a first heating element unit 90, and the air entering from the first air inlet 213 of each first cover body 21 flows through the corresponding first flow channel area 215 and flows through the first heating element unit 90 located in the first flow channel area 215 for heat dissipation, and flows out from the corresponding first air outlet 214 and blows to the rear side of the substrate 1, but the present invention is not limited thereto.

[0023] When in use, the first heating element unit 90 may be installed and configured according to the actual situation, for example Figure 1 In the installation state shown in FIG. 1 , since the first heating element unit 90 is not installed in the first flow channel area 215 of one of the first housings 21, the corresponding first baffle plate 23 is moved to a position to cover the corresponding first flow channel area 215 and because the first baffle plate 23 is as shown in FIG. Figure 2 As shown, the corresponding first flow channel area 215 is blocked so that the wind cannot flow out from the corresponding first air outlet 214, and the overall flow resistance of the corresponding first cover body 21 is greatly increased. At this time, most of the airflow inflowing from the front side of the server will automatically flow into the first air inlet 213 of the other first cover body 21 in the direction of small flow resistance, flow through the corresponding first flow channel area 215, flow through the first heating element unit 90 in the first flow channel area 215 for heat dissipation, and then flow out from the corresponding first air outlet 214, effectively ensuring good heat dissipation efficiency.

[0024] In this embodiment, the initial position of each first baffle plate 23 is located at a position that does not block the corresponding first flow channel area 215, and the first clamping protrusion 232 of the first protrusion unit 231 of each first baffle plate 23 is as follows: Figure 5 As shown in FIG. 1 , the first retaining groove 222 of the first track unit 22 is inserted into the first retaining groove 222 and the first limiting protrusion 233 is located above the first vertical track 223, and each first baffle plate 23 is as shown in FIG. Figure 5 Here, it is further described that the assembly action of moving one of the first baffle plates 23 to block the corresponding first flow channel area 215 is to first move the first limiting protrusion 233 downward and simultaneously move the first clamping protrusion 232 out of the first clamping groove 222, and then continue to move the first limiting protrusion 233 downward into the first vertical track 223 (see Figure 6 ), and move the first baffle plate 23 so that Figure 7 The first baffle plate 23 is in an upright state as shown in the figure, and the corresponding flow channel area is blocked. At this time, the first clamping protrusion 232 of the first protrusion unit 231 of the first baffle plate 23 corresponds to the first upper positioning groove 225, and the first limiting protrusion 233 corresponds to the first lower positioning groove 226. Finally, as long as the first baffle plate 23 is moved toward the corresponding first air outlet 214 and the first clamping protrusion 232 is moved into the first upper positioning groove 225 and the first limiting protrusion 233 is moved into the first lower positioning groove 226, the first baffle plate 23 is as shown in the figure. Figure 7 The first baffle plate 23 is shown as blocking the corresponding first flow channel area 215, and the assembly action is completed. Relatively speaking, if the first baffle plate 23 is to be moved back to the initial position where it does not block the corresponding first flow channel area 215, it is only necessary to move the first baffle plate 23 away from the corresponding first air outlet 214 and move the first clamping protrusion 232 away from the first upper positioning groove 225, and simultaneously move the first limiting protrusion 233 away from the first lower positioning groove 226. Then, the first clamping protrusion 232 is moved upward and moved into the first horizontal track 221 (see Figure 6 ), continue to move the first clamping protrusion 232 toward the first clamping groove 222 so that the first clamping protrusion 232 is as shown in Figure 5 The first clamping groove 222 is inserted into the first vertical rail 223, and the first limiting protrusion 233 is located above the first vertical rail 223. At this time, the first baffle 23 is as shown in FIG. Figure 5In short, the first retaining protrusion 232 of each first protrusion unit 231 of each first baffle plate 23 can move between the first retaining groove 222, the first horizontal track 221 and the first upper positioning groove 225, and the first limiting protrusion 233 of each first protrusion unit 231 can move between the first vertical track 223 and the first lower positioning groove 226, so that each first baffle plate 23 can move between the fixed track paths in the track unit and can be moved to the position as required according to actual use. Figure 7 As shown, the position of the corresponding first flow channel area 215 is blocked or moved back to Figure 5 As shown, the position of the corresponding first flow channel area 215 cannot be blocked.

[0025] By means of the design that the first track unit 22 of each first cover body 21 is recessed inside the first side plate 212 of each first cover body 21 and the first boss unit 231 of each first baffle plate 23 can be moved relative to the first track unit 22, and in conjunction with the application that any first baffle plate 23 can be moved to a position to block the corresponding first flow channel area 215, when no electronic components requiring heat dissipation are arranged in the first flow channel area 215 of one of the first cover bodies 21, by moving the corresponding first baffle plate 23 to a position to block the corresponding first flow channel area 215, the overall flow resistance of the first cover body 21 having no heat dissipation requirement inside can be increased, thereby achieving more airflow entering the first air inlet 213 of the other first cover body 21 having heat dissipation requirement and flowing through the corresponding first flow channel area 215 for heat dissipation, thereby effectively ensuring good heat dissipation efficiency.

[0026] It should be particularly noted that, in this embodiment, each first air deflector device 2 further includes a first sealing unit 24 disposed on each first cover body 21 and located in each first flow channel area 215 and adjacent to the first air outlet 214. Each first cover body 21 also has a first combination frame 216 corresponding to the first air outlet 214 and connecting the first top plate 211 and the first side plate 212. Each first sealing unit 24 is fixedly disposed on each first combination frame 216. When the first clamping protrusion 232 of any first baffle plate 23 is clamped into the first upper positioning groove 225 of the first positioning groove module 224 and the first limiting protrusion 233 is clamped into the first lower positioning groove 226, at this time, the first baffle plate 23 blocks the corresponding first flow channel area 215 and the first baffle plate 23 abuts against the corresponding first sealing unit 24, and the first sealing unit 24 blocks the gap between the first baffle plate 23 and the first top plate 211 and the gap between the first baffle plate 23 and the first side plate 212. That is to say, when each first baffle plate 23 moves to a position that blocks the corresponding first flow channel area 215, each first baffle plate 23 and the corresponding first combining frame 216 have a spacing distance, so that there is a gap between each first baffle plate 23 and the corresponding first air outlet 214. Therefore, the first sealing unit 24 will block the gap between the first baffle plate 23 and the first top plate 211 and the gap between the first baffle plate 23 and the first side plate 212, thereby preventing the wind flow fluid from flowing out from the gap between each first baffle plate 23 and the corresponding first cover body 21. In particular, when the wind flow fluid flows to each first baffle plate 23 and is blocked by the first baffle plate 23, the wind flow fluid is blocked by the corresponding first baffle plate 23, so that the wind flow fluid is converted from dynamic pressure to static pressure and the corresponding first baffle plate 23 is pushed toward the direction of the corresponding first sealing unit 24, and the first baffle plate 23 and the corresponding first sealing unit 24 are more closely fitted to achieve a better sealing effect, but it is not limited to this. In this embodiment, the first sealing unit 24 of each first air guide device 2 is in the form of a first elastic sealing strip adhered to each first combination frame 216, but the present invention is not limited thereto, and other fixing methods may also be used, as long as each first sealing unit 24 can be fixedly combined with each first combination frame 216. Each first elastic sealing strip is made of a soft elastic material, but the present invention is not limited thereto.

[0027] In addition, in this embodiment, the first baffle plate 23 of the first air guide cover device 2 further has a ventilation hole unit 234, and the ventilation hole unit 234 has a plurality of ventilation holes 235. That is to say, if the actual installation configuration is, for example Fig. 9In the installation state shown in the figure, although the first heating element unit 90 is not installed in the first flow channel area 215 of the first cover body 21, a small third heating element unit 91 is arranged outside the first air outlet 214 of the first cover body 21 to dissipate heat, so the following can be selected: Fig. 9 The first baffle plate 23 shown has the ventilation hole unit 234. When the first baffle plate 23 moves to a position that blocks the corresponding first flow channel area 215, the ventilation hole unit 234 of the first baffle plate 23 is provided with the ventilation hole 235, so that part of the wind can flow through the ventilation hole 235 and flow out from the corresponding first air outlet 214, and flow through the third heating element unit 91 for heat dissipation, thereby achieving effective cooling of the third heating element unit 91, but not limited to this.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9Here, it is further explained that, in this embodiment, two second air deflector devices 3 are also provided on the first air deflector device 2. Each second air deflector device 3 includes a second cover body 31 provided on the first top plate 211 of the first cover body 21 of the corresponding first air deflector device 2, and a second baffle plate 33 provided on the second cover body 31. Each second cover body 31 has a second top plate 311, two second side plates 312 extending from two opposite sides of the second top plate 311 toward the first top plate 211 and provided on the first top plate 211, and two second track units 32 respectively recessed in the inner side of the second side plates 312. Each second top plate 311 and the second side plates 312 jointly define a second air inlet 313, a second air outlet 314, and a second flow channel area 315 located between the second air inlet 313 and the second air outlet 314. Each second baffle plate 33 is close to the second air outlet 314 and can be controlled to move to block the corresponding second flow channel area 315. Each second baffle plate 33 has two second boss units (not numbered in the figure) located on two opposite sides and extending into the second track unit 32 respectively and movable relative to the second track unit 32. Each second track unit 32 has a second horizontal track 321 parallel to each second top plate 311, a second vertical track 323 perpendicular to the second horizontal track 321 and connected to the second horizontal track 321 and close to the corresponding second air outlet 314, and a second positioning slot module 324 close to the second air outlet 314. Each second horizontal track 321 has a second clamping slot 322 away from the second air outlet 314. Each second positioning slot module 324 has a second upper positioning slot 325 connected to the second horizontal track 321 and extending from the second horizontal track 321 to the direction of the second air outlet 314, and a second lower positioning slot 326 connected to the second vertical track 323 and extending from the second vertical track 323 to the direction of the second air outlet 314. Each second boss unit of each second baffle 33 has a second clamping boss (not numbered in the figure) that can be adjusted to move between the second clamping slot 322, the second horizontal track 321 and the second upper positioning slot 325, and a second limiting boss (not numbered in the figure) that can be adjusted to move between the second vertical track 323 and the second lower positioning slot 326. In this embodiment, the structure of each second baffle 33 is substantially the same as that of each first baffle 23, and only the size is different, so each second baffle 33 can refer to Figure 4The structural state of each first baffle 23 is not separately illustrated. When the second clamping boss of the second boss unit of any second baffle 33 is clamped into the second clamping groove 322 of the second track unit 32, at this time, the second baffle 33 does not block the corresponding second flow channel area 315; when the second clamping boss of any second baffle 33 is clamped into the second upper positioning groove 325 of the second positioning groove module 324 and the second limiting boss is clamped into the second lower positioning groove 326, at this time, the second baffle 33 blocks the corresponding second flow channel area 315. In short, the second air guide cover device 3 of this embodiment is as follows: Figure 1 As shown, the stack is disposed on the first top plate 211 of the first cover body 21 of the first air deflector device 2. The initial position of each second baffle plate 33 is not to block the corresponding second flow channel area 315. The assembly action of moving each second baffle plate 33 to block the corresponding second flow channel area 315 is the same as the assembly step of moving each first baffle plate 23 to block the corresponding first flow channel area 215, which is not repeated here, or the assembly action of moving each second baffle plate 33 back to the point where it cannot block the corresponding second flow channel area 315 is the same as the assembly step of moving each first baffle plate 23 back to the point where it cannot block the corresponding first flow channel area 215, which is not repeated here. Furthermore, in this embodiment, the second air outlet 314 of the second cover body 31 of the second air deflector device 3 respectively corresponds to two second heating element units (not shown) located on the rear side of the substrate 1, and the air entering from the second air inlet 313 of each second cover body 31 flows through the corresponding second flow channel area 315 and flows out from the corresponding second air outlet 314 and blows to the corresponding second heating element unit located on the rear side of the substrate 1. In other words, the second air deflector device 3 can be configured to meet the actual requirements of the second heating element unit being arranged on the rear side. By the way, in this embodiment, the height position of the second air deflector device 3 is coordinated with the height position of the second heating element unit arranged on the rear side, so the airflow flowing out from the second air outlet 314 of the second cover body 31 of the second air deflector device 3 will be directly blown to the second heating element unit on the rear side for heat dissipation. Relatively speaking, if the second heating element unit is not arranged on the rear side and there is no need to meet the heat dissipation requirement of the airflow flowing out through the second air outlet 314 of the second cover body 31, it is sufficient to move the second baffle plate 33 to block the corresponding second flow channel area 315 and prevent the airflow from flowing out from the corresponding second air outlet 314.

[0029] It should be further explained that, in this embodiment, each second air deflector device 3 also includes a second sealing unit 34 disposed on each second cover body 31 and located in each second flow channel area 315 and adjacent to the second air outlet 314. Each second cover body 31 also has a second combination frame 316 corresponding to the second air outlet 314 and connecting the second top plate 311 and the second side plate 312. Each second sealing unit 34 is fixed on each second combination frame 316. When the second clamping protrusion of any second baffle plate 33 is clamped into the second upper positioning groove 325 of the second positioning groove module 324 and the second limiting protrusion is clamped into the second lower positioning groove 326, at this time, the second baffle plate 33 blocks the corresponding second flow channel area 315 and the second baffle plate 33 abuts against the corresponding second sealing unit 34, and the second sealing unit 34 blocks the gap between the second baffle plate 33 and the second top plate 311 and the gap between the second baffle plate 33 and the second side plate 312. That is to say, when each second baffle plate 33 moves to a position that blocks the corresponding second flow channel area 315, each second baffle plate 33 and the corresponding second combining frame 316 have a spacing distance, so that there is a gap between each second baffle plate 33 and the corresponding second air outlet 314. Therefore, the second sealing unit 34 will block the gap between the second baffle plate 33 and the second top plate 311 and the gap between the second baffle plate 33 and the second side plate 312, so as to prevent the wind flow fluid from flowing out from the gap between each second baffle plate 33 and the corresponding second cover body 31. In particular, when the wind flow fluid flows to each second baffle plate 33 and is blocked by the second baffle plate 33, the wind flow fluid is blocked by the corresponding second baffle plate 33, so that the wind flow fluid is converted from dynamic pressure to static pressure and the corresponding second baffle plate 33 is pushed toward the direction of the corresponding second sealing unit 34, so that the second baffle plate 33 and the corresponding second sealing unit 34 are more closely fitted to achieve a better sealing effect, but not limited to this. In this embodiment, the second sealing unit 34 of each second air deflector device 3 is in the form of a second elastic sealing strip bonded to each second combination frame 316, but the present invention is not limited thereto, and other fixing methods are also possible, as long as each second sealing unit 34 can be fixedly combined to each second combination frame 316. Each second elastic sealing strip is made of a soft elastic material, but the present invention is not limited thereto.

[0030] In summary, the server of the present invention, by means of the design that the first track unit 22 of each first cover body 21 is recessed inside the first side plate 212 of each first cover body 21 and the first boss unit 231 of each first baffle plate 23 can be moved relative to the first track unit 22, and in conjunction with the application that any first baffle plate 23 can be moved to a position to block the corresponding first flow channel area 215, when no electronic components requiring heat dissipation are arranged in the first flow channel area 215 of one of the first cover bodies 21, by moving the corresponding first baffle plate 23 to a position to block the corresponding first flow channel area 215, the overall flow resistance of the first cover body 21 having no heat dissipation requirement inside can be increased, thereby achieving more airflow entering the first air inlet 213 of another first cover body 21 having heat dissipation requirement and flowing through the corresponding first flow channel area 215 for heat dissipation, thereby effectively ensuring good heat dissipation efficiency.

[0031] However, what is described above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope covered by the patent of the present invention.
