DETAILED DESCRIPTION

[0044] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0045] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0046] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0047] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0048] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0049] There are two types of servers on the market. One is dedicated to storage or simple computing, so the CPU usage requirements are relatively low, and the corresponding CPU operating temperature is also relatively low; the other is to cope with the development of big data and AI applications. Servers need to be equipped with high-performance GPU modules, and the CPU operating temperature will also increase accordingly. However, the heat of the CPU needs to be dissipated through the radiator, and then the heat is drained out through the air duct. There are usually two structural forms of CPU radiators, such as Fig.10 The type I heat sink shown is used for CPUs operating at low temperatures, such as Fig.11The T-type heat sink shown is used for CPUs working at high temperatures, but these two heat sinks need to be matched with different air guides. The air guides currently on the market have poor compatibility and are not compatible with the above two heat sinks. And when the server is equipped with a high-performance GPU module, due to its long structure size and heavy weight, it will vibrate during operation, and its rear end needs to be supported to ensure stable signal transmission of the GPU module.

[0050] Graphics Processing Unit (GPU), also known as display core, visual processor, display chip, is a microprocessor dedicated to image computing on personal computers, workstations, game consoles and some mobile devices (such as tablets, smart phones, etc.).

[0051] The central processing unit (CPU) is one of the main devices of an electronic computer and the core component of a computer. Its main function is to interpret computer instructions and process data in computer software.

[0052] like Figure 1-Figure 6 As shown, according to the first aspect of an embodiment of the present application, there is provided an air guide cover 100, comprising a main body 1 and a plurality of air duct baffles 2; the main body 1 is provided with at least one group of vent groups 11, each group of the vent groups 11 comprising at least one first vent 111 and a plurality of second vents 112; the air duct baffle 2 is detachably connected to the main body 1; the air duct baffle 2 is arranged at the second vent 112 or at one end of the main body 1 away from the second vent 112.

[0053] like Figure 1 and Figure 2 As shown, the air guide cover 100 includes a main body 1 and a plurality of air duct baffles 2, wherein the air duct baffles 2 are detachably connected to the main body 1.

[0054] More specifically, at least one set of vent groups 11 is provided on the body 1 , and one set of vent groups 11 corresponds to one heat sink 201 . Each set of vent groups 11 is provided with at least one first vent 111 and a plurality of second vents 112 .

[0055] To further illustrate, the first ventilation opening 111 and the second ventilation opening 112 are located at different horizontal planes, and the plurality of second ventilation openings 112 are located at the same horizontal plane.

[0056] It can be understood that the vent group 11 is provided with a first vent 111 and a plurality of second vents 112. The I-type radiator 201 has an air outlet, which is arranged corresponding to the first vent 111. The T-type radiator 201 has a plurality of air outlets, which correspond one to one with the first vent 111 and the plurality of second vents 112. Therefore, the main body 1 is provided with a first vent 111 and a plurality of second vents 112, which can adapt to both the I-type radiator 201 and the T-type radiator 201.

[0057] It can also be understood that the vent group 11 has more than two first vents 111 and a plurality of second vents 112. It can be applicable to a radiator 201 having more than two I-type radiators 201 or having two air outlets located on the same horizontal plane.

[0058] More specifically, the air duct baffle 2 is disposed at the second vent 112 or at an end of the body 1 away from the second vent 112 .

[0059] Among them, Figure 2 and Fig.10 As shown, for the I-type radiator 201, the I-type radiator 201 has only one air outlet, so the air outlet of the I-type radiator 201 corresponds to the first vent 111. Therefore, the air duct baffle 2 is arranged at the second vent 112 to block the second vent 112.

[0060] like Figure 1 and Fig.11 As shown, for the T-shaped radiator 201, the T-shaped radiator 201 has a plurality of air outlets, and the sum of the plurality of air outlets and the first vent 111 and the second vent 112 is the same, so the plurality of air outlets correspond to the first vent 111 and the second vent 112 one by one. The air duct baffle 2 is arranged at one end of the body 1 away from the second vent 112 to avoid blocking the second vent 112. In addition, the server 300 equipped with the GPU module 302 usually adopts the T-shaped radiator 201, and the air duct baffle 2 is arranged at one end of the body 1 away from the second vent 112. The support plate 3021 of the GPU module 302 is clamped on the air duct baffle 2, and the air duct baffle 2 can support the GPU module 302 to avoid abnormal contact of the GPU module 302 due to the self-weight problem or the server 300 when performing vibration testing, so as to ensure stable signal transmission.

[0061] Therefore, the air guide cover 100 provided in the present application is applicable to both I-type radiators 201 and T-type radiators 201 , and the air duct baffle 2 can also provide support for the GPU module 302 .

[0062] In an optional implementation, the air duct baffle 2 is provided at the second vent 112 and at an end of the body 1 away from the second vent 112 .

[0063] In this embodiment, the server 300 used by the I-type heat sink 201 is equipped with a GPU module 302. Therefore, an air duct baffle 2 is provided at the second vent 112 to shield the second vent 112, and an air duct baffle 2 is also provided at one end of the body 1 away from the second vent 112 to support the GPU module 302.

[0064] In an optional implementation, there are two second vents 112 , and the first vent 111 is disposed between the two second vents 112 .

[0065] Further, each vent group 11 includes a first vent 111 and two second vents 112, the two second vents 112 are arranged at intervals, and the first vent 111 is located between the two second vents 112. Among them, the air outlet of the I-type heat sink 201 corresponds to the first vent 111, the first vent 111 is located between the two second vents 112, and the air outlet of the I-type heat sink 201 discharges air from the middle position, which can make the CPU heat dissipation more uniform to avoid the situation of high local temperature.

[0066] In an optional embodiment, the body 1 includes a base plate 12 and a plurality of mounting portions 13; the mounting portions 13 are disposed on the base plate 12; and the air duct baffle 2 is detachably connected to the mounting portions 13.

[0067] like Figure 2 As shown, the body 1 includes a bottom plate 12 and a plurality of mounting portions 13 , wherein the mounting portions 13 are disposed on the bottom plate 12 ; the bottom plate 12 includes a first side 123 and a second side 124 , wherein the first side 123 and the second side 124 are disposed opposite to each other.

[0068] More specifically, the first vent 111 and the plurality of second vents 112 are disposed on the bottom plate 12 and bulge in a direction away from the bottom plate 12 , and the first vent 111 is closer to the first side 123 than the second vent 112 .

[0069] Multiple mounting portions 13 are provided on the bottom plate 12. Among them, mounting portions 13 are provided at the second vent 112 and near the first side 123, so that the air duct baffle 2 can be installed at the second vent 112, or installed on the side of the body 1 away from the second vent 112. The mounting portion 13 of the second vent 112 is used to install the air duct baffle 2 that blocks the second vent 112, and the mounting portion 13 near the first side 123 is used to install the air duct baffle 2 that supports the GPU module 302. The air duct baffle 2 installed by the mounting portions 13 at different positions has different functions. Multiple mounting portions 13 are provided on the bottom plate 12 to facilitate the installation of the air duct baffle 2; the air duct baffle 2 is detachably connected to the mounting portion 13, so the air duct baffle 2 can be installed at the second vent 112 and / or near the first side 123 as needed.

[0070] In an optional embodiment, the air duct baffle 2 includes a wind shield portion 21, and a first clamping portion 214 is provided on a side of the wind shield portion 21 close to the base plate 12, and the mounting portion 13 includes a second clamping portion 131, and the wind shield portion 21 and the mounting portion 13 are clamped together via the first clamping portion 214 and the second clamping portion 131.

[0071] like Figure 3 and Figure 4 As shown, the air duct baffle 2 includes a wind shielding portion 21 , wherein the size of the wind shielding portion 21 is slightly larger than the size of the second vent 112 , so that the wind shielding portion 21 can shield the second vent 112 .

[0072] Among them, a first clamping portion 214 is provided on the side of the wind shield 21 close to the base plate 12, and the mounting portion 13 includes a second clamping portion 131. The first clamping portion 214 and the second clamping portion 131 are clamped together, so that the wind shield 21 and the mounting portion 13 are installed; when it is necessary to remove the air duct baffle 2 from the base plate 12, the first clamping portion 214 and the second clamping portion 131 are released from the coupling, so that the air duct baffle 2 can be removed from the base plate 12.

[0073] Further explanation, it can be understood that the first clamping portion 214 includes two spaced-apart clamping plates, the second clamping portion 131 includes two spaced-apart limiting plates, and a receiving cavity is formed between the limiting plates and the bottom plate 12. The air duct baffle 2 moves toward the second clamping portion 131 to push the clamping plate into the receiving cavity between the limiting plate and the bottom plate 12 to connect the air duct baffle 2 to the bottom plate 12; when the air duct baffle 2 needs to be removed, it is only necessary to move the air duct baffle 2 away from the second clamping portion 131 to move the clamping plate out of the receiving cavity between the limiting plate and the bottom plate 12, thereby releasing the connection between the air duct baffle 2 and the bottom plate 12.

[0074] It can also be understood as Figure 4As shown, the first engaging portion 214 includes two hooks 215 arranged opposite to each other, and a receiving groove 2151 is formed between the hook 215 and the wind shielding portion 21 ; the second engaging portion 131 includes two connecting plates 1311 arranged opposite to each other, and the connecting plates 1311 are engaged in the receiving groove 2151 .

[0075] More specifically, the first engaging portion 214 includes two hooks 215, the two hooks 215 are arranged at intervals, and a receiving groove 2151 is formed between the hooks 215 and the bottom of the wind shielding portion 21. The second engaging portion 131 includes two connecting plates 1311, the two connecting plates 1311 are arranged at intervals. The air duct baffle 2 moves toward the second engaging portion 131 so that the connecting plates 1311 enter the receiving groove 2151, thereby connecting the air duct baffle 2 to the bottom plate 12; when the air duct baffle 2 needs to be removed, it is only necessary to move the air duct baffle 2 in a direction away from the second engaging portion 131 so that the connecting plates 1311 are separated from the receiving groove 2151, thereby releasing the connection between the air duct baffle 2 and the bottom plate 12.

[0076] In an optional embodiment, the base plate 12 is provided with an avoidance hole 121, the connecting plate 1311 is provided on the side wall of the avoidance hole 121 and extends along the length direction of the air guide cover 100, and the hook 215 is located in the avoidance hole 121 and is engaged with the connecting plate 1311.

[0077] like Figure 5 and Figure 6 As described above, the bottom plate 12 is provided with an avoidance hole 121 , the connecting plate 1311 is arranged on the side wall of the avoidance hole 121 and extends along the length direction of the air guide cover 100 , and the hook 215 is located in the avoidance hole 121 .

[0078] Further, the length of the connecting plate 1311 is less than the length of the avoidance hole 121, and the hook 215 moves toward the connecting plate 1311 along the width direction of the air scoop 100 at the avoidance hole 121, so that the hook 215 is located in the avoidance hole 121, and the connecting plate 1311 can be clamped in the receiving groove 2151. The avoidance hole 121 can provide an avoidance effect for the hook 215.

[0079] To further explain, the connecting plate 1311 does not extend to the other side wall of the avoidance hole 121 to provide an avoidance function for the hook 215 .

[0080] In an optional embodiment, the mounting portion 13 includes a guide column 132; the air duct baffle 2 also includes a connecting portion 22, the connecting portion 22 is connected to the wind shielding portion 21, the connecting portion 22 is provided with a slide groove 221, the length direction of the slide groove 221 is the same as the width direction of the air guide cover 100, and the guide column 132 extends into the slide groove 221 and abuts against the inner wall of the slide groove 221.

[0081] like Figure 6 As shown, the mounting portion 13 includes a guide column 132 , and the guide column 132 extends in a direction away from the base plate 12 .

[0082] The air duct baffle 2 also includes a connecting portion 22 connected to the wind shielding portion 21 . A slide groove 221 is provided on the connecting portion 22 . The length direction of the slide groove 221 is the same as the width direction of the air guide cover 100 , and the height of the guide column 132 is greater than the height of the slide groove 221 .

[0083] When installing the air duct baffle 2, the slide groove 221 is aligned with the guide column 132, so that the guide column 132 extends into the slide groove 221, and the sliding air duct baffle 2 moves toward the direction of the second engaging portion 131. The slide groove 221 moves relative to the guide column 132, and the guide column 132 abuts against the inner wall of one end of the slide groove 221, and the first engaging portion 214 is engaged with the second engaging portion 131. The abutment of the guide column 132 against one end of the slide groove 221 will limit the air duct baffle 2 from moving further, so as to play a role of limiting and improve the installation efficiency.

[0084] In an optional implementation, a first limiting portion is provided on the connecting portion 22 , and a second limiting portion is provided on the bottom plate 12 , and the first limiting portion cooperates with the second limiting portion.

[0085] Further, a first limiting portion is provided on the connecting portion 22, and a second limiting portion is provided on the bottom plate 12. After the first engaging portion 214 is engaged with the second engaging portion 131, the first limiting portion cooperates with the second limiting portion to prevent the first engaging portion 214 from moving in the width direction of the air guide cover 100, thereby improving the connection stability between the air duct baffle 2 and the bottom plate 12.

[0086] Among them, Figure 4 and Figure 6 As shown, the first limiting portion is a limiting protrusion 222, and the second limiting portion is a limiting hole 122. After the air duct baffle 2 and the mounting portion 13 are installed, the limiting protrusion 222 will cooperate with the limiting hole 122, that is, the limiting protrusion 222 is stuck in the limiting hole 122 to limit the movement of the air duct baffle 2 relative to the width direction of the air guide cover 100, thereby improving the connection stability between the air duct baffle 2 and the base plate 12.

[0087] In addition, the first limiting portion can be a limiting hole 122, and the second limiting portion can be a limiting protrusion 222. After the air duct baffle 2 and the mounting portion 13 are installed, the limiting protrusion 222 will cooperate with the limiting hole 122, that is, the limiting protrusion 222 is stuck in the limiting hole 122 to limit the movement of the air duct baffle 2 relative to the width direction of the air guide cover 100, thereby improving the connection stability between the air duct baffle 2 and the base plate 12.

[0088] In an optional implementation, the air duct baffle 2 further includes a lifting portion 23 , which extends in a direction away from the bottom plate 12 and is connected to the connecting portion 22 .

[0089] like Figure 3 and Figure 4 As shown, the air duct baffle 2 further includes a lifting portion 23, which extends in a direction away from the bottom plate 12, and is connected to the connecting portion 22. By lifting the lifting portion 23 in a direction away from the bottom plate 12, the first limiting portion can be separated from the second limiting portion, so as to release the limiting relationship between the first limiting portion and the second limiting portion, that is, the limiting of the air duct baffle 2 and the bottom plate 12 in the width direction of the air guide cover 100 is released, so that the air duct baffle 2 is easily removed from the bottom plate 12.

[0090] In an optional implementation, a first extending portion 211 and a second extending portion 212 are provided on a side of the wind shielding portion 21 away from the connecting portion 22 , and a cavity is formed between the first extending portion 211 and the second extending portion 212 .

[0091] like Figure 3 and Figure 4 As shown, when the air duct baffle 2 is disposed at one end of the body 1 away from the second vent 112, the first extension portion 211 and the second extension portion 212 are located at one side of the air duct baffle 2 away from the second vent 112. A cavity is formed between the first extension portion 211 and the second extension portion 212, and the support plate 3021 of the GPU module 302 is stuck in the cavity to prevent the GPU module 302 from shaking, to prevent the GPU card from contacting abnormally due to its own weight or when the server 300 is subjected to a vibration test, and to ensure stable signal transmission.

[0092] In an optional implementation, a notch 213 is formed on the side wall of the wind shielding portion 21 , and the notch 213 is located between the first extending portion 211 and the second extending portion 212 .

[0093] like Figure 3 As shown, the support plate 3021 of the GPU module 302 is stuck in the notch 213 and inserted into the cavity of the first extension portion 211 and the second extension portion 212. The notch 213, the first extension portion 211 and the second extension portion 212 limit the support plate 3021 of the GPU module 302, thereby limiting the up and down shaking of the GPU module 302.

[0094] In an optional implementation, the vent groups 11 include two groups, and the two groups of vent groups 11 are arranged at intervals. Multiple groups of vent groups 11 can be provided with multiple heat sinks 201 to improve the heat dissipation effect.
