[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] In order to solve the problem that the structure of the air guide cover of the server in the prior art is relatively simple and cannot meet the effective heat dissipation requirements of heating elements at different positions, resulting in the server being unable to operate normally, the present invention provides an air guide cover for the server.

[0064] Embodiment 1

[0065] like Figures 1 to 4 As shown, the air guide cover for the server includes a cover body 10 and a plurality of guide members 20, wherein the plurality of guide members 20 are arranged at intervals on the same side surface of the cover body 10, and divide the cover body 10 into a plurality of ventilation ducts 30, each ventilation duct 30 has an air duct inlet 31 and an air duct outlet 32; wherein the ventilation duct 30 at least flows through a first heat dissipation area 101 of the server chassis 1, so as to perform heat dissipation treatment for a module to be cooled located in the first heat dissipation area 101; the air duct inlet 31 is used to communicate with at least two adjacent fans 102 on the server chassis 1, and at least part of the air duct outlet 32 ​​is used to communicate with a second heat dissipation area 103 of the server chassis 1 located behind the first heat dissipation area 101, so as to perform heat dissipation treatment for the module to be cooled located in the second heat dissipation area 103.

[0066] By providing a plurality of guide members 20, the cover body 10 is divided into a plurality of ventilation ducts 30, and the ventilation ducts 30 are provided in a structural form that flows through at least the first heat dissipation area 101 of the server chassis 1, thereby achieving the purpose of heat dissipation treatment for the heat dissipation module located in the first heat dissipation area 101; in addition, by using the duct inlet 31 to communicate with at least two adjacent fans 102 on the server chassis 1, each ventilation duct 30 can correspond to at least two fans 102 to provide wind for it, ensuring that each ventilation duct 30 has sufficient air volume, and each ventilation duct 30 It is possible to centrally blow air to dissipate heat for the corresponding areas, thereby achieving the purpose of each ventilation duct 30 performing its respective function; in addition, when a single ventilation duct 30 is provided with air by at least two fans 102, when one of the fans 102 is in a faulty state, the other fan 102 can continue to provide air to the ventilation duct 30 for continuous heat dissipation treatment; further, at least part of the air duct outlet 32 ​​is used to communicate with the second heat dissipation area 103 of the server chassis 1 located behind the first heat dissipation area 101, thereby achieving heat dissipation treatment for the heat dissipation module located in the second heat dissipation area 103.

[0067] The air guide hood provided in the present application can realize different ventilation ducts 30 corresponding to the heat dissipation modules to be cooled in different heat dissipation areas, thereby ensuring the air guiding reliability and accuracy of the air guide hood while ensuring the heat dissipation reliability of the heat dissipation modules to be cooled and ensuring that each heat dissipation module can operate normally.

[0068] like Figure 1 As shown, the cover body 10 is used to cover the area behind the fan 102 wall of the server chassis 1 and in front of the second heat dissipation area 103.

[0069] It should be noted that, in this embodiment, each guide member 20 is integrally formed with the cover body 10. In this way, the connection reliability of each guide member 20 and the cover body 10 is ensured, and it is ensured that there is no air leakage at the connection between each guide member 20 and the cover body 10, so as to ensure that the wind flowing through the ventilation duct 30 can dissipate heat to the modules to be dissipated in the corresponding areas to be dissipated as much as possible.

[0070] like Figures 2 to 4As shown, the air guide 20 includes a plurality of second partition plates 21, which are arranged at intervals on the cover body 10, and a wind duct outlet 32 ​​is formed between the first ends of two adjacent second partition plates 21 among the plurality of second partition plates 21; wherein the air guide 20 has at least one second partition plate 21 of two adjacent second partition plates 21, the length of which is greater than the length of the second second partition plate 21; the air guide 20 also includes an air guide structure 22, the first end of the air guide structure 22 is connected to the second end of the second second partition plate 21, the second end of the air guide structure 22 extends along a side close to the first second partition plate 21 and forms an air guide port 227 between the second end of the first second partition plate 21, and the air guide port 227 is used to guide the wind to the CPU module 105 located in the first heat dissipation area 101. In this way, it is ensured that the wind flowing through the CPU module 105 in the first heat dissipation area 101 can effectively dissipate the heat of the CPU module 105, thereby ensuring that the CPU module 105 can operate normally.

[0071] like Figure 4 As shown, the cross-sectional area of ​​the inlet section of the air guide port 227 is smaller than the cross-sectional area of ​​the outlet section of the air duct outlet 32. In this way, by setting the cross-sectional area of ​​the inlet section of the air guide port 227 to be smaller than the cross-sectional area of ​​the outlet section of the air duct outlet 32, the wind flowing through the ventilation duct 30 can be concentrated as much as possible to perform heat dissipation treatment on the CPU module 105 after entering the first heat dissipation area 101, thereby ensuring the heat dissipation reliability of the CPU module 105.

[0072] like Figures 2 to 4 As shown, the air guide 20 includes two groups of partition plates, each of which includes two second partition plates 21; the air guide 20 includes two air guide structures 22 arranged in pairs, and the two air guide structures 22 correspond to the two groups of partition plates one by one; wherein, an air duct inlet 31 is formed between the second ends of the two air guide structures 22 arranged in pairs, and the air duct inlet 31 is connected to the air guide port 227. In this way, it is ensured that the wind blown out by the fan 102 can enter the ventilation duct 30 through the air duct inlet 31 and the air guide port 227 in sequence and perform heat dissipation for the CPU module 105 located in the first heat dissipation area 101.

[0073] like Figure 3 and Figure 4As shown, in the direction from the guide port 227 to the air duct outlet 32, the guide structure 22 includes a first sub-plate segment 2262 and a second sub-plate segment 2263 connected to each other, and the first sub-plate segment 2262 and the second sub-plate segment 2263 are arranged at an angle; wherein, the first end of the second sub-plate segment 2263 is connected to the second end of the second second partition plate 21, the second end of the second sub-plate segment 2263 is connected to the first end of the first sub-plate segment 2262, the second end of the first sub-plate segment 2262 extends along a side close to the first second partition plate 21 and forms a guide port 227 with the second end of the first second partition plate 21; there is a first angle A between the second sub-plate segment 2263 and the second second partition plate 21, and there is a second angle B between the first sub-plate segment 2262 and the second second partition plate 21; the first angle A and the second angle B satisfy: A>B. In this way, it is beneficial to concentrate the wind on the CPU module 105 located in the first heat dissipation area 101, so as to effectively dissipate the heat of the CPU module 105 located in the first heat dissipation area 101.

[0074] like Figures 1 to 4 As shown, in the direction of wind flow, the two first sub-plate segments 2262 arranged in pairs are arranged in a trumpet shape, and the two second sub-plate segments 2263 arranged in pairs are arranged in a trumpet shape. In this way, the wind entering the same air duct inlet 31 is divided into multiple sub-wind flows and flows to different partitions respectively, so as to perform heat dissipation treatment for the CPU modules 105 on both sides of the middle part of the first heat dissipation area 101 respectively, and at the same time, perform independent heat dissipation for the memory module 104 located between the two CPU modules 105, so as to ensure that different ventilation ducts 30 can perform their respective functions. Figure 2 The arrow C shows the direction of wind flow.

[0075] like Figure 3 and Figure 4 As shown, in the flow direction of the wind, at least the top wall surface 35 of the duct of the ventilation duct 30 flowing through the first heat dissipation area 101 where the memory module 104 is placed is extended in a downwardly inclined shape to direct the wind downward to the location of the memory module 104. In this way, by setting the top wall surface 35 of the duct of the ventilation duct 30 flowing through the first heat dissipation area 101 where the memory module 104 is placed in a downwardly inclined extended structure, the top wall surface 35 of the duct directs the wind downward to the location of the memory module 104, thereby achieving the purpose of heat dissipation for the memory module 104.

[0076] like Figure 3As shown, the air guide cover also includes a first partition plate 50, which is arranged in the ventilation duct 30 flowing through the first heat dissipation area 101 where the memory module 104 is placed, and divides the ventilation duct 30 into a first sub-duct 33 and a second sub-duct 34 that are connected; wherein, the duct top wall surface 35 of the first sub-duct 33 extends in a downwardly inclined shape, and the channel side wall surface of the second sub-duct 34 away from the first sub-duct 33 is provided with an avoidance gap 341. In this way, when the air guide cover is installed on the server chassis 1, the setting of the avoidance gap 341 facilitates the operator to take and place the air guide cover through the avoidance gap 341, thereby ensuring the convenience of installation of the air guide cover. Furthermore, the setting of the first partition plate 50 plays a role in concentrating the wind in the first sub-duct 33 as much as possible, and the wind is guided to the memory module 104 by the duct top wall surface 35 of the first sub-duct 33 extending in a downwardly inclined shape, so as to effectively dissipate the heat for the memory module 104.

[0077] like Figure 3 As shown, the wind guide cover also includes a wind resistance structure 40, which is arranged at the air duct outlet 32, and there are multiple wind resistance structures 40, and the multiple wind resistance structures 40 correspond to the multiple air duct outlets 32. In this way, the arrangement of the wind resistance structure 40 is conducive to increasing the wind resistance in the ventilation duct 30, avoiding excessive wind flow in a single ventilation duct 30 and seriously affecting other areas with large wind resistance, and excessive wind resistance difference will cause wind to pass through the ventilation duct 30 with smaller wind resistance.

[0078] It should be noted that, in this embodiment, each wind resistance structure 40 is integrally formed with the cover body 10. In this way, the connection reliability of each wind resistance structure 40 and the cover body 10 is ensured, which is conducive to preventing air leakage at the connection between each wind resistance structure 40 and the cover body 10.

[0079] It should be noted that, in the present embodiment, there are multiple wind resistance structures 40, and at least one wind resistance structure 40 among the multiple wind resistance structures 40 is provided with a ventilation hole. Thus, by providing ventilation holes on at least one wind resistance structure 40 among the multiple wind resistance structures 40, it is beneficial to increase the wind resistance in the ventilation duct 30, and avoid excessive wind flow in a single ventilation duct 30 to seriously affect other areas with large wind resistance, and excessive wind resistance difference will cause wind to pass through the ventilation duct 30 with smaller wind resistance.

[0080] like Figure 3 As shown, the same wind resistance structure 40 has multiple ventilation holes 41, and the number of ventilation holes 41 on at least two wind resistance structures 40 among the multiple wind resistance structures 40 is inconsistent. In this way, it is convenient to adapt the corresponding ventilation duct 30 according to the specific layout of the modules to be cooled in the first cooling area 101.

[0081] like Figure 3As shown, the cross-sectional area of ​​the outlet section of at least the first air duct outlet 32 ​​among the multiple air duct outlets 32 is greater than the cross-sectional area of ​​the outlet section of the second air duct outlet 32; wherein, the cross-sectional area S1 of the hole section of a single ventilation hole 41 on the first wind resistance structure 40 located at the first air duct outlet 32 ​​and the cross-sectional area S2 of the hole section of a single ventilation hole 41 on the second wind resistance structure 40 located at the second air duct outlet 32 ​​satisfy: S1≤S2. In this way, after the wind at the memory module 104 in the middle of the first heat dissipation area 101 undergoes heat exchange with the memory module 104, part of the wind can be discharged through the ventilation holes 41 at the second wind resistance structure 40, and another part of the wind can be discharged through the gaps in the memory module 104; after the wind at the two CPU modules 105 in the first heat dissipation area 101 undergoes heat exchange with the CPU module 105, it is discharged through the ventilation holes 41 at the first wind resistance structure 40. According to the different wind resistances generated by the specific structural shape of the CPU module 105, the ventilation holes 41 can be opened at the first wind resistance structure 40 to achieve the purpose of adjusting the second wind resistance structure 40 to achieve the same wind resistance, thereby ensuring that the windflow passes through the CPU module 105 for heat exchange.

[0082] It should be noted that, in the present application, the cross-section of the ventilation hole 41 is at least one of a circular shape, an elliptical shape, and a polygonal shape.

[0083] Embodiment 2

[0084] like Figures 5 to 10 As shown, the difference between this embodiment and the first embodiment is that the wind guide cover further includes a wind resistance structure 40, which is arranged at the air duct outlet 32, and there are multiple wind resistance structures 40, and the multiple wind resistance structures 40 correspond to the multiple air duct outlets 32 one by one; wherein, at least one wind resistance structure 40 among the multiple wind resistance structures 40 is detachably connected to the cover body 10 located at the air duct outlet 32. At least one wind resistance structure 40 among the multiple wind resistance structures 40 is provided with a ventilation hole 41, and each wind resistance structure 40 is detachably connected to the cover body 10 located at the air duct outlet 32; wherein, the number N1 of the wind resistance structures 40 and the number N2 of the air duct outlets 32 satisfy: N1≥N2, so that different wind resistance structures 40 can be selectively adapted at the same air duct outlet 32. The same wind resistance structure 40 has multiple ventilation holes 41, and the number of ventilation holes 41 on at least two wind resistance structures 40 among the multiple wind resistance structures 40 is inconsistent.

[0085] By applying the specific scheme of this embodiment, the wind resistance generated by the specific appearance shape of the module to be cooled in the first area 101 to be cooled can be adjusted by replacing the wind resistance structure 40 with ventilation holes 41, or replacing the wind resistance structure 40 with a specific number of ventilation holes 41 that can meet the wind resistance requirements, or replacing the wind resistance structure 40 without ventilation holes 41, thereby achieving the wind resistance conditions of different modules to be cooled in the first area 101 to be cooled. This ensures that the wind can blow to the designated module to be cooled as much as possible for effective heat dissipation.

[0086] like Figures 5 to 10 As shown, a wind resistance structure 40 is movably provided at least at the air duct outlet 32 ​​for communicating with the second area to be dissipated heat 103 .

[0087] like Figure 8 As shown, the cover body 10 at the air duct outlet 32 ​​is provided with a pair of guide grooves 11, and the groove wall of the guide groove 11 is provided with a first clamping groove 111; the wind resistance structure 40 is slidably matched with the guide groove 11, and both sides of the wind resistance structure 40 have a first buckle 42 for clamping with the first clamping groove 111. In this way, the wind resistance structure 40 is ensured to be detachably connected to the cover body 10 in a sliding manner, and the reliability and stability of the connection between the two are ensured, while ensuring the convenience of installation and disassembly between the two.

[0088] like Figure 8 As shown, a limiting groove 12 may be further provided on the cover body 10 at the air duct outlet 32, and the two ends of the limiting groove 12 are respectively used to communicate with the two guide grooves 11; a limiting protrusion 121 is protruding from the bottom surface of the limiting groove 12, and a limiting notch 43 is provided at the position of the wind resistance structure 40 opposite to the limiting protrusion 121, so that the wind resistance structure 40 is limited on the cover body 10 through the cooperation of the limiting notch 43 and the limiting protrusion 121. In this way, the setting of the limiting groove 12 plays a role in positioning the wind resistance structure 40, and the limiting protrusion 121 in the limiting groove 12 cooperates with the limiting notch 43 on the wind resistance structure 40, thereby achieving the guiding and limiting effect on the wind resistance structure 40, and further ensuring the installation stability of the wind resistance structure 40.

[0089] like Fig. 9 and Fig.10 As shown, the two figures show two different embodiments thereof, namely, a wind resistance structure 40 with different numbers of ventilation holes 41, and a wind resistance structure 40 without ventilation holes 41; of course, different wind resistance structures 40 in other forms may also be combined and matched to form coordination with different air duct outlets 32, which will not be described in detail here.

[0090] Embodiment 3

[0091] In an embodiment not shown in the figure of the present application, the difference between this embodiment and embodiment one is that the wind guide cover also includes a wind resistance structure 40, and the wind resistance structure 40 is arranged at the air duct outlet 32, and there are multiple wind resistance structures 40, and the multiple wind resistance structures 40 correspond one by one to the multiple air duct outlets 32; wherein, at least one of the multiple guide members 20 is detachably connected to the cover body 10.

[0092] By setting at least one of the multiple guide members 20 to be a structural form that is detachably connected to the cover body 10, it is ensured that by replacing different guide members 20, the opening size of the air duct inlet 31 of a single ventilation duct 30 can be adjusted, thereby achieving adjustment of the number of fans 102 corresponding to the air duct inlet 31 of the single ventilation duct 30, and further achieving adjustment of the air volume and wind force of the single ventilation duct 30.

[0093] Embodiment 4

[0094] like Figures 11 to 18 As shown, the difference between this embodiment and the first embodiment is that the air guide cover also includes a wind resistance structure 40, which is arranged at the air duct outlet 32, and there are multiple wind resistance structures 40, and the multiple wind resistance structures 40 correspond one by one to the multiple air duct outlets 32; wherein, at least one of the multiple wind resistance structures 40 is detachably connected to the cover body 10 located at the air duct outlet 32; and at least one of the multiple guide members 20 is detachably connected to the cover body 10.

[0095] By arranging at least one of the multiple wind resistance structures 40 to be detachably connected to the cover body 10 located at the air duct outlet 32; and arranging at least one of the multiple guide members 20 to be detachably connected to the cover body 10, the wind resistance generated by the specific appearance shape of the module to be cooled in the first heat dissipation area 101 can be adjusted by replacing the wind resistance structure 40 with ventilation holes 41, or replacing the wind resistance structure 40 with a specific number of ventilation holes 41 that can meet the wind resistance requirements, or replacing the wind resistance structure 40 without ventilation holes 41, thereby ensuring that the wind can blow to the designated module to be cooled as much as possible for effective heat dissipation.

[0096] In addition, by setting at least one of the multiple guide members 20 to be detachably connected to the cover body 10, it is ensured that by replacing different guide members 20, the opening size of the air duct inlet 31 of the single ventilation duct 30 can be adjusted, thereby achieving adjustment of the number of fans 102 corresponding to the air duct inlet 31 of the single ventilation duct 30, and further achieving adjustment of the air volume and wind force of the single ventilation duct 30.

[0097] like Fig.11 and Fig.12 As shown, the guide member 20 includes two second partition plates 21 and a guide structure 22, wherein the two second partition plates 21 are spaced apart on the cover body 10, and a duct outlet 32 ​​is formed between the first ends of the two second partition plates 21; the guide structure 22 has a guide channel 221 and a guide inlet 222 and a guide outlet 223 connected to the guide channel 221, the ends of the channel arms on both sides of the guide channel 221 located at the guide outlet 223 are respectively connected to the second ends of the two second partition plates 21, and a guide inlet 222 is formed at one end of the guide channel 221 away from the second partition plate 21; wherein the guide structure 22 is detachably connected to the second partition plate 21; and / or the guide structure 22 is detachably connected to the cover body 10. In this way, the convenience of installation and disassembly of the guide member 20 and the cover body 10 is ensured, and the airflow blown out by the fan 102 can be adaptively adjusted according to the heat dissipation requirements of different CPU modules 105 in the first heat dissipation area 101 and the configuration of the server. For example, when the CPU module 105 is replaced with a higher wattage or a higher air inlet temperature, it is necessary to increase the air duct inlet 31 by replacing the guide member 20, so that the original air duct inlet 31 corresponds to two fans 102 for the original CPU module 105 at that location, and is changed to 3 or 4 fans 102 for the replaced CPU module 105 at that location. This replacement that is only applicable to the CPU module 105 corresponds to adjusting the size of the air duct inlet 31 by replacing the guide member 20, so as to achieve the purpose of adapting the air duct inlet 31 to different numbers of fans 102.

[0098] like Fig.11 and Fig.12 As shown, the cross-sectional area of ​​the inlet section of the guide inlet 222 is smaller than the cross-sectional area of ​​the outlet section of the guide outlet 223. In this way, it is ensured that the high-temperature wind after the heat exchange operation can be discharged in time to take away the heat generated by the CPU module 105.

[0099] like Fig.11 and Fig.12 As shown, the air guide 20 includes two groups of partition plate groups, each of which includes two second partition plates 21; the air guide 20 includes multiple groups of guide structure groups, and the same group of guide structure groups includes two guide structures 22 arranged in pairs, and the two guide structures 22 in the same group of guide structure groups correspond to the two groups of partition plate groups one by one; wherein, an air duct inlet 31 is formed between the two guide structures 22 arranged in pairs in the same group of guide structure groups, and the air duct inlet 31 is connected to the guide inlet 222. In this way, it is ensured that the wind blown out by the fan 102 passes through the air duct inlet 31 and the guide inlet 222 in sequence and flows through the CPU module 105, and takes away the heat generated by the CPU module 105.

[0100] Furthermore, each group of guide structure groups is detachably connected to the cover body 10 so that the cover body 10 can be selectively adapted to different groups of guide structure groups; wherein, the opening sizes of the air duct inlet 31 formed between the two guide structures 22 arranged in pairs in each group of guide structure groups are inconsistent so as to adapt to different numbers of adjacent fans 102. In this way, the convenience of installation and disassembly of the guide member 20 and the cover body 10 is ensured, and the airflow blown out by the fan 102 can be adaptively adjusted according to the heat dissipation requirements of different CPU modules 105 in the first heat dissipation area 101 and the configuration of the server. For example, when the CPU module 105 is replaced with a higher wattage or a higher air inlet temperature, it is necessary to increase the air duct inlet 31 by replacing the guide member 20, so that the original air duct inlet 31 corresponds to two fans 102 for the original CPU module 105 at that location, and is changed to 3 or 4 fans 102 for the replaced CPU module 105 at that location. This replacement that is only applicable to the CPU module 105 corresponds to adjusting the size of the air duct inlet 31 by replacing the guide member 20, so as to achieve the purpose of adapting the air duct inlet 31 to different numbers of fans 102.

[0101] like Figures 11 to 13 As shown, the guide structure 22 includes a supporting bottom plate 224, a first guide plate 225 and a second guide plate 226, wherein the support bottom plate 224 is provided with a second buckle 2241 protruding from the surface of the side facing the cover body 10, and a second snap-fitting groove 13 is provided at a position of the cover body 10 opposite to the second buckle 2241, so that the support bottom plate 224 is mounted on the cover body 10 through the cooperation and positioning of the second buckle 2241 and the second snap-fitting groove 13; the first guide plate 225 is connected to the support bottom plate 224 and extends in a direction away from the side of the cover body 10, and the outer surface of the first guide plate 225 away from the guide channel 221 is convex. A first guide slider 2251 is provided, and a first guide slot 211 is provided at the end of the second end of the second partition plate 21 corresponding to the same side, and the first guide slider 2251 is slidably matched with the first guide slot 211; the second guide plate 226 is connected to the support bottom plate 224 and extends in a direction away from the side of the cover body 10, and a second guide slider 2261 is protrudingly provided on the outer surface of the second guide plate 226 away from the guide channel 221, and a second guide slot 212 is provided at the end of the second end of the second partition plate 21 corresponding to the same side, and the second guide slider 2261 is slidably matched with the second guide slot 212. In this way, the guide structure 22 and the cover body 10 are matched in a sliding manner, and the sliding direction of the guide structure 22 is consistent with the flow direction of the wind, ensuring the connection reliability and stability between the guide structure 22 and the cover body 10, and ensuring the convenience of installation and disassembly between the guide structure 22 and the cover body 10.

[0102] like Figures 14 to 16As shown, the first guide plate 225 has a stop surface on its outer surface facing away from the guide channel 221, and the stop surface is arranged toward the second partition plate 21 corresponding to the same side; wherein, the end of the first guide slider 2251 sliding into the first guide slot 211 is connected to the stop surface, so that when the first guide slider 2251 slides into place in the first guide slot 211, the stop surface abuts against the end surface of the second end of the second partition plate 21 corresponding to the same side; and / or, a limit buckle 14 is protrudingly provided on the cover body 10, and the limit buckle 14 has a slot on the side facing the air duct inlet 31; the limit buckle 14 is staggered with the second snap-fitting groove 13, and the second snap-fitting groove 13 is arranged closer to the air duct inlet 31 than the limiting snap-fitting groove 14, so that when the air guide structure 22 is installed in place, at least part of the support bottom plate 224 is snapped into the slot of the limiting snap-fitting groove 14; and / or, a limiting protrusion 15 is protrudingly arranged on the cover body 10, and the limiting protrusion 15 is staggered with the second snap-fitting groove 13, and the second snap-fitting groove 13 is arranged closer to the air duct inlet 31 than the limiting protrusion 15, so that when the air guide structure 22 is installed in place, at least part of the edge of the support bottom plate 224 abuts and cooperates with the limiting protrusion 15. In this way, the installation stability of the air guide structure 22 is ensured.

[0103] like Fig.17 and Fig.18 As shown, in the direction from the guide inlet 222 to the guide outlet 223, the second guide plate 226 includes a first sub-plate segment 2262, a second sub-plate segment 2263, and a third sub-plate segment 2264 connected in sequence, and the first sub-plate segment 2262, the second sub-plate segment 2263, and the third sub-plate segment 2264 are arranged at an angle with each other; wherein the third sub-plate segment 2264 is consistent with the extension direction of the second partition plate 21 corresponding to the same side, the second sub-plate segment 2263 and the third sub-plate segment 2264 have a first angle A, and the first sub-plate segment 2262 and the third sub-plate segment 2264 have a second angle B; the first angle A and the second angle B satisfy: A>B. In this way, it is beneficial to concentrate the wind at the CPU module 105 located in the first heat dissipation area 101, so as to effectively dissipate the heat for the CPU module 105 located in the first heat dissipation area 101.

[0104] like Fig.17 and Fig.18As shown, the guide member 20 includes two groups of guide structure groups, the first angle A between the second sub-plate segment 2263 and the third sub-plate segment 2264 of the guide structure 22 in the first group of guide structure groups is greater than the first angle A between the second sub-plate segment 2263 and the third sub-plate segment 2264 of the guide structure 22 in the second group of guide structure groups; and / or, the second angle B between the first sub-plate segment 2262 and the third sub-plate segment 2264 of the guide structure 22 in the first group of guide structure groups is greater than the second angle B between the first sub-plate segment 2262 and the third sub-plate segment 2264 of the guide structure 22 in the second group of guide structure groups. In this way, according to Fig.17 and Fig.18 It can be seen that Fig.17 is the first group of diversion structures, Fig.18 This is the second group of diversion structures. It is obvious that Fig.18 The opening of the air duct inlet 31 is larger than Fig.17 The air duct inlet 31 in the Fig.18 The air duct inlet 31 of the second group of guide structure groups can be adapted to a larger number of fans 102 .
