Description

Technical Field

[0001] This application relates to the technical field of servers, and particularly to a heat dissipation module and a server. Background Art

[0002] Servers mostly adopt diversified configurations to meet various functional requirements. Among them, from the perspective of the rear window, a 2U (Unit, a unit representing the height dimension of a server) server chassis includes hard disks, GPUs (Graphics Processing Unit), PCIe (Peripheral Component Interconnect Express, network adapters with PCIe interfaces), etc. The hard disks are installed with hard disk trays, and the heat dissipation requirements of the hard disks have been considered in the initial design of the hard disk trays. With the development of GPUs, PCIe, etc., more and more PCIe cards have put forward higher requirements for heat dissipation while improving their performance.

[0003] Currently, some chassis will add a secondary air guide cover at the rear to dissipate heat from the rear window module. Not only does it require reserving a certain structural design space and locking structure for adding the air guide cover on the chassis, which poses a great challenge to the chassis that has been designed, but there are also cases where the heat dissipation test still fails. For example, high-heat dissipation components such as BF3 (i.e., BlueField3 network chip) and DPU (Data Processing Unit) still cannot meet their heat dissipation requirements after adding the air guide cover secondarily. Summary of the Invention

[0004] This application provides a heat dissipation module and a server to at least solve the problem of effectively cooling high-heat dissipation demand modules in different areas of the rear window of the chassis in the related art.

[0006] A telescopic beam, one end of the telescopic beam is fixed on the chassis, and the other end is telescopically arranged along the first direction, and the telescopic beam has telescopic points corresponding to the heat dissipation areas one by one;

[0007] A heat dissipation device, including a bracket and a fan assembly arranged on the bracket. The bracket is installed at the other end of the telescopic beam, and the bracket is configured to move telescopically with the other end of the telescopic beam to the telescopic point, so that the fan assembly dissipates heat from the heat dissipation area corresponding to the telescopic point.

[0008] The present application also provides a server, including a chassis and the heat dissipation module described in any one of the above, wherein an installation space is formed on the chassis extending along the first direction, and the heat dissipation module is disposed in the installation space.

[0009] Through the present application, the telescopic beam is formed into a telescopic structure, one end of which is connected to the chassis, and the other end moves relative to the chassis along the first direction, and the other end can correspond to different heat dissipation areas during the telescopic process, so that the telescopic beam has telescopic points corresponding to the heat dissipation areas. When the heat dissipation device is connected to the other end of the telescopic beam away from the chassis, the heat dissipation device can be driven by the telescopic beam to change positions corresponding to at least two telescopic points, so as to discharge air corresponding to different heat dissipation areas on the chassis. Therefore, the heat dissipation device can achieve directional heat dissipation for the heat dissipation areas with high heat dissipation requirements, solve the problem of poor heat dissipation effect, meet different usage requirements, the fan assembly can output stable wind force and a sufficient size of air flow, realize good heat dissipation inside the entire chassis, ensure the good operation of the entire server, and extend the service life of the server.

[0041] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0042] An embodiment of the present application provides a heat dissipation module, which is installed on a chassis 5 of a server. The heat dissipation module includes a telescopic beam 1 and a heat dissipation device 2.

[0043] Wherein, at least two heat dissipation areas to be dissipated are arranged on the chassis 5 along a first direction. One end of the telescopic beam 1 is fixed to the chassis 5, and the other end is telescopically arranged along the first direction, and the telescopic beam 1 has telescopic points corresponding to the heat dissipation areas one by one. That is to say, during the telescopic process of the telescopic beam 1 along the first direction, it can correspond to the heat dissipation areas on the chassis 5 one by one, so that it itself has a plurality of telescopic points with the same number as the heat dissipation areas.

[0044] The heat dissipation device 2 includes a bracket 21 and a fan assembly disposed on the bracket 21. The bracket 21 is installed at the other end of the telescopic beam 1, and the bracket 21 is configured to move telescopically with the other end of the telescopic beam 1 to a telescopic position point, so that the fan assembly dissipates heat from the heat dissipation area corresponding to the telescopic position point.

[0045] In specific implementation, the telescopic beam 1 is formed as a telescopic structure, one end of which is connected to the chassis 5, and the other end moves relative to the chassis 5 in the first direction, and the other end can correspond to different heat dissipation areas during the telescopic process, so that the telescopic beam 1 has telescopic position points corresponding to the heat dissipation areas. When the heat dissipation device 2 is connected to the other end of the telescopic beam 1 away from the chassis 5, the telescopic beam 1 can drive the heat dissipation device 2 to change positions corresponding to at least two telescopic position points, so as to blow air to different heat dissipation areas on the chassis 5. Therefore, through the heat dissipation device 2, directional heat dissipation for the heat dissipation area with high heat dissipation requirements can be achieved, the problem of poor heat dissipation effect can be solved, different usage requirements can be met, the fan assembly can output stable wind force and sufficient air flow, good heat dissipation inside the entire chassis 5 can be realized, the good operation of the entire server can be ensured, and the service life of the server can be extended.

[0046] Exemplarily, referring to Figure 1 As shown, the rear window of the 2U-height chassis 5 can accommodate at most 8 full-height PCIe cards, at least two heat dissipation areas are formed in the chassis 5, and the at least two heat dissipation areas include a first area 51, a second area 52 and a third area 53. The first area 51 and the second area 52 can each accommodate 3 full-height PCIe cards, and the third area 53 can accommodate 2 full-height PCIe cards.

[0047] Among them, the 2 full-height PCIe cards in the third area 53 are located above the power supply frame of the chassis 5. Since there is sufficient space and air flow in the third area 53, specific heat dissipation requirements can be achieved by adding a wind guide cover for the second time.

[0048] There are 3 PCIe cards in the first area 51 and the second area 52, and the heat dissipation requirement is higher than that of the third area 53. When the first area 51 is a high heat dissipation requirement area, setting the heat dissipation device 2 at the telescopic position point corresponding to the first area 51 can blow air to the first area 51 directionally through the heat dissipation device 2; when the second area 52 is a high heat dissipation requirement area, setting the heat dissipation device 2 at another telescopic position point corresponding to the second area 52 can blow air to the second area 52 directionally through the heat dissipation device 2. It can be understood that the fan 23 can output stable wind force and sufficient air flow, which can meet the high heat dissipation requirements of the first area 51 and the second area 52.

[0049] Generally speaking, the first region 51 and the second region 52 can define different functional requirements that can be achieved by different PCIe cards at the initial design stage. The heat dissipation requirements of different PCIe cards are also different. Therefore, when installing the heat dissipation device 2, the heat dissipation device 2 can be directly aligned with the region to be cooled with higher heat dissipation requirements in the first region 51 and the second region 52. When the heat dissipation device 2 is aligned with the first region 51, the space of the second region 52 can be arranged with other modules according to other requirements, and a high space utilization rate can be ensured inside the chassis 5.

[0050] Specifically, the telescopic beam 1 is formed into a telescopic structure so that the telescopic beam 1 can have a first telescopic position where it retracts and a second telescopic position where it extends. When the telescopic beam 1 is arranged on the chassis 5 and the bracket 21 is connected to the telescopic beam 1, the bracket 21 has two positions relative to the chassis 5, so that the fan 23 can blow air corresponding to different regions to be cooled of the chassis 5 to achieve the purpose of heat dissipation.

[0051] Specifically, when the telescopic beam 1 is in the first telescopic position, the telescopic beam 1 retracts to correspond to the first region 51 on the chassis 5. At this time, one side of the bracket 21 is connected to the telescopic beam 1, and the other side can be connected to the chassis 5 through the fastener 3. The shape of the bracket 21 can be adapted to the position of the support column 54 reserved on the chassis 5 itself. In this way, the bracket 21 and the fan assembly arranged on the bracket 21 can be fixed inside the chassis 5 to ensure the connection stability.

[0052] When the telescopic beam 1 is in the second telescopic position, the telescopic beam 1 extends to correspond to the second region 52 on the chassis 5. At this time, one side of the bracket 21 is connected to the telescopic beam 1, and the other side can be connected to the chassis 5 through the connecting member 4. In this way, the bracket 21 and the fan assembly arranged on the bracket 21 can be fixed inside the chassis 5. When the telescopic beam 1 and the connecting member 4 can be respectively connected to the opposite side walls of the chassis 5, the support performance of the chassis 5 can also be improved, and the overall structural strength of the chassis 5 can be ensured. Among them, the telescopic beam 1 and the connecting member 4 can be connected through the installation holes of the cross beam reserved on the chassis 5 itself for supporting the GPU, without additional modification of the structure of the chassis 5, and the existing 2U height chassis 5 structure can be directly utilized.

[0053] It should be noted that the regions to be cooled on the chassis 5 can also be four, five or more. The present application does not limit this. As long as the telescopic beam 1 can have multiple telescopic positions corresponding to multiple regions to be cooled, so as to drive the heat dissipation device 2 to blow air to different regions to be cooled corresponding to different telescopic positions, the heat dissipation module has high versatility.

[0054] In some embodiments, the telescopic beam 1 includes an inner rail 11 and an outer shell 12, the inner rail 11 can be slidably inserted in the outer shell 12, and the bracket 21 is installed at one end of the inner rail 11. It can be understood that the interior of the outer shell 12 is formed as a cavity structure, the inner rail 11 is arranged in the cavity structure, and can slide relative to the outer shell 12 to achieve the telescopic function, and then can drive the bracket 21 arranged at one end of the inner rail 11 to move accordingly, so as to face different areas to be cooled for blowing and cooling. Specifically, the outer shell 12 can be screwed to the chassis 5 by screws and bolts, etc., or can be riveted to the chassis 5 by rivets, etc.

[0055] The inner rail 11 is provided with a plug-in portion 111, and the outer shell 12 is provided with at least two plug-in holes 121. The plug-in holes 121 correspond to the telescopic points one by one. When the inner rail 11 drives the bracket 21 to move to the telescopic point, the plug-in portion 111 is plugged into the corresponding plug-in hole 121, that is, the plug-in portion 111 can be plugged into different plug-in holes 121 switchably, so that the inner rail 11 has multiple telescopic points relative to the outer shell 12. In other words, when the plug-in portion 111 is plugged into different plug-in holes 121, the inner rail 11 extends out to different distances relative to the outer shell 12, thereby enabling the bracket 21 on the inner rail 11 to move to different telescopic points accordingly. Further, when the plug-in portion 111 is plugged into the plug-in hole 121, the inner rail 11 and the outer shell 12 can be relatively fixed, so as to ensure that the bracket 21 and the fan assembly are fixed in position in the chassis 5, thereby achieving stable air discharge of the fan 23 and ensuring the heat dissipation effect.

[0056] Exemplarily, the number of the plug-in holes 121 is two, and the inner rail 11 has two telescopic points that are stable relative to the outer shell 12. Correspondingly, when the bracket 21 is arranged on the inner rail 11, it can dissipate heat in a directional manner corresponding to the two areas to be cooled.

[0057] Of course, the number of the plug-in holes 121 on the housing 12 can also be three, four or more, and the present application does not impose any limitation on this. As long as the plug-in portion 111 is plugged into the plug-in hole 121 so that the telescopic beam 1 has multiple telescopic points, the heat dissipation device 2 can be driven to discharge air to different heat dissipation areas corresponding to different telescopic points. The specific settings can be made according to actual needs.

[0058] In some embodiments, reference Figure 8 and Figure 9 As shown, a button 13 and a connecting rod assembly 14 are also provided on the inner rail 11. One end of the connecting rod assembly 14 is connected to the button 13, and the other end is connected to the plug-in portion 111. The button 13 and the plug-in portion 111 are linked and cooperated through the connecting rod assembly 14, so that the plug-in portion 111 can be inserted into the plug-in hole 121 and the plug-in portion 111 can be removed from the plug-in hole 121 by manually operating the button 13.

[0059] The inner rail 11 is provided with a hole for the insertion part 111 to extend and retract. The insertion part 111 is configured to retract into the inner rail 11 from the hole when the button 13 is pressed, so that the insertion part 111 can be disengaged from the insertion hole position 121, thereby realizing the position adjustment of the inner rail 11 relative to the outer shell 12; and when the button 13 is released, it extends out of the inner rail 11 from the hole, so that the insertion part 111 can be inserted into the insertion hole position 121, thus making the position of the inner rail 11 on the outer shell 12 relatively fixed.

[0060] Of course, the extension and retraction of the insertion part 111 can also be realized by relying on other structures, and the present application does not limit this. As long as the insertion part 111 can protrude from the outer contour surface of the inner rail 11 so that the insertion part 111 can be inserted into the insertion hole position 121, and the insertion part 111 can retract into the outer contour surface of the inner rail 11 so that the insertion part 111 can be disengaged from the insertion hole position 121, it can be specifically set according to actual needs.

[0061] It should be noted that, referring to Figure 2 and Figure 4 As shown, when the insertion part 111 is inserted into different insertion hole positions 121, the button 13 can be exposed outside the outer shell 12, thereby leaving an operation space for the human hand and facilitating the control of the extension and retraction of the inner rail 11 corresponding to different expansion and contraction points.

[0062] In some embodiments, still referring to Figure 8 and Figure 9 As shown, the link assembly 14 includes a first rotating member 141, a connecting line 142 and a second rotating member 143. One end of the connecting line 142 is connected to the first rotating member 141, and the other end is connected to the second rotating member 143. The first rotating member 141 and the second rotating member 143 are both rotatably connected to the inner rail 11. The button 13 is arranged on the first rotating member 141, and the insertion part 111 is arranged on the second rotating member 143. When the button 13 is pressed, the first rotating member 141 can rotate, so as to drive the second rotating member 143 to rotate through the connecting member 4, and further drive the insertion part 111 on the second rotating member 143 to extend out of the inner rail 11 or retract into the inner rail 11. In this way, the linkage cooperation between the button 13 and the insertion part 111 can be realized.

[0063] The first rotating member 141 is connected to the inner rail 11 through the first elastic member 144 at a position away from the rotation center. When the first rotating member 141 rotates, it can drive the first elastic member 144 to deform. The button 13 is arranged at one end of the first rotating member 141 away from the connecting line 142, so that when the button 13 moves, the other end of the first rotating member 141 connected to the connecting line 142 can be driven to move through the lever principle. The second rotating member 143 is connected to the inner rail 11 through the second elastic member 145 at a position away from the rotation center. When the second rotating member 143 moves through the connecting line 142, it can drive the second elastic member 145 to deform. The plug-in portion 111 is arranged on one end of the second rotating member 143 away from the connecting line 142, so that when the second rotating member 143 moves, the plug-in portion 111 and the other end thereof can be driven to move through the lever principle.

[0064] In specific implementation, a first rotating shaft is provided on the inner rail 11, and the first rotating member 141 is sleeved on the first rotating shaft, and the first rotating shaft serves as the rotation center of the first rotating member 141. A second rotating shaft is provided on the inner rail 11, and the second rotating member 143 is sleeved on the second rotating shaft, and the second rotating shaft serves as the rotation center of the second rotating member 143. Specifically, the first rotating member 141 and the second rotating member 143 are fixed to the inner rail 11 through step studs, and the step portions of the step studs can be formed as the first rotating shaft and the second rotating shaft, respectively, to realize the rotation connection of the first rotating member 141 and the second rotating member 143 on the inner rail 11.

[0065] For example, refer to Figure 8 and Figure 9 As shown, the first rotating member 141 and the second rotating member 143 form an L-shaped structure, the first rotating member 141 includes a first transverse arm and a first longitudinal arm set at an acute angle, and the connection between the first transverse arm and the first longitudinal arm forms a rotation center, the second rotating member 143 includes a second transverse arm and a second longitudinal arm set at an acute angle, and the connection between the second transverse arm and the second longitudinal arm forms a rotation center, the acute angle openings of the first rotating member 141 and the second rotating member 143 are in the same direction, the button 13 is set on the first transverse arm, the first elastic member 144 is connected to the inner rail 11 and the first longitudinal arm, the plug-in portion 111 is set on the second transverse arm, and the second elastic member 145 is connected to the inner rail 11 and the second transverse arm, that is, the plug-in portion 111 is located between the rotation center of the second rotating member 143 and the second elastic member 145.

[0066] Of course, it should be noted that the first rotating member 141 and the second rotating member 143 can also be structural members of other shapes, or be arranged in other ways. The present application does not limit this, as long as the linkage cooperation between the button 13 and the plug-in portion 111 can be achieved, so that the plug-in portion 111 can be driven by the button 13 to be inserted into the plug-in hole 121, and the plug-in portion 111 can be driven to be removed from the plug-in hole 121.

[0067] Meanwhile, the first rotating member 141 and the second rotating member 143 can also be connected to the inner rail 11 through an elastic section or a flexible section. Specifically, the elastic section or the flexible section can be a rubber section, a silicone section, etc. This application does not limit this, and it can be specifically set according to the actual situation.

[0068] Specifically, the interior of the inner rail 11 is formed as a hollow structure. The first rotating member 141, the connecting line 142, and the second rotating member 143 are all disposed within this hollow structure. The button 13 is provided on the side wall of the hollow structure. By pressing the button 13, the first rotating member 141 can be driven to move. The insertion portion 111 is disposed within a hole opened on the side wall of the hollow structure, so as to drive the insertion portion 111 to extend out of the hole or retract into the hole through the second rotating member 143.

[0069] In some embodiments, referring to Figure 12 and Figure 13 As shown, the bracket 21 includes a frame body 211, a first connecting arm 212 and a second connecting arm 213 respectively disposed on both sides of the frame body 211. The first connecting arm 212 is fixedly connected to the telescopic beam 1. Specifically, the first connecting arm 212 can be fixedly connected to the telescopic beam 1 by riveting, and the connection strength is high.

[0070] The second connecting arm 213 is alternatively connected to one of a plurality of support columns 54 on the bottom wall of the chassis 5 and a connecting member 4 on the side wall of the chassis 5. The support columns 54 and the connecting member 4 are respectively provided corresponding to one telescopic point. That is to say, corresponding to different telescopic points of the telescopic beam 1, it can be connected to different positions on the chassis 5. Specifically, when the bracket 21 corresponds to the first telescopic point of the telescopic beam 1, the second connecting arm 213 is connected to the support column 54 on the bottom wall of the chassis 5. A through hole is provided on the second connecting arm 213, and it is connected to the support column 54 through a fastener 3 passing through the through hole. When the bracket 21 corresponds to the second telescopic point of the telescopic beam 1, the second connecting arm 213 is connected to the connecting member 4 on the side wall of the chassis 5. The connecting member 4 can be fixed to the side wall of the chassis 5 by screwing or riveting, so as to support the telescopic beam 1, the heat dissipation device 2, and the connecting member 4 on opposite side walls of the chassis 5 in sequence.

[0071] Specifically, when implemented, the frame body 211 is in a semi-enclosed structure. The fan assembly is disposed on the frame body 211, which is convenient for installation, and the fan assembly and the frame body 211 can be respectively connected to the chassis 5 through the first connecting arm 212 and the second connecting arm 213.

[0072] Specifically, referring to Figure 6 and Figure 7As shown, a slot 41 is provided inside the connecting member 4, and the second connecting arm 213 can be inserted into the slot 41 and fixed by a fixing member. That is, when the bracket 21 is disposed corresponding to the second area 52 of the chassis 5, the second connecting arm 213 is connected to the chassis 5 through the connecting member 4. Specifically, through holes are provided on the side wall of the slot 41, and through holes are also provided on the second connecting arm 213. After the fixing member passes through the side wall of the slot 41 and the second connecting arm 213, the connection between the second connecting arm 213 and the connecting member 4 can be achieved.

[0073] It should be noted that the shape of the connecting member 4 can be designed according to the internal structure of the chassis 5 itself. When installing the connecting member 4, the existing connection holes of the chassis 5 can be used without modifying the chassis 5. Further, the positions where the heat dissipation device 2 and the telescopic beams 1 and the connecting member 4 on its left and right are located are the installation positions for supporting the GPU cross beam in a 2U-height chassis 5. Therefore, the motherboard restriction area and the GPU cross beam support columns 54 below it can all be used, which can ensure the universality of the heat dissipation module of the present application in a 2U-height chassis 5.

[0074] In some embodiments, referring to Figure 10 and Figure 11 As shown, the fan assembly includes a fan frame 22 and a fan 23 disposed inside the fan frame 22.

At the same time, it can also align the installation direction of the fan frame 22 on the bracket 21, improving the installation efficiency.

[0076] Specifically, the top edges of the opposite side walls of the frame body 211 form two guiding edges 214, and two guiding grooves 221 are correspondingly provided on the fan frame 22. The two guiding edges 214 are respectively installed and matched with the two guiding grooves 221. Further, a second anti-fooling hole 227 is provided on one of the guiding grooves 221, and an anti-fooling protrusion 215 is provided on one of the guiding edges 214.

[0077] Continue to refer to Figure 10 and Figure 11As shown, the fan frame 22 includes an air inlet frame 222 and an air outlet frame 223, the air inlet frame 222 and the air outlet frame 223 are respectively connected to opposite sides of the fan 23, a space for accommodating the fan 23 is formed between the air inlet frame 222 and the air outlet frame 223, and the air inlet frame 222 and the air outlet frame 223 are both formed as hollow structures to facilitate air to enter the space between the air inlet frame 222 and the air outlet frame 223 for circulation. Specifically, the air inlet frame 222 and the air outlet frame 223 are both sheet metal structures with sufficient structural strength.

[0078] The air inlet frame 222 is provided with a first foolproofing column 224, the air outlet frame 223 is provided with a second foolproofing column 225, and the fan 23 is provided with two first foolproofing holes 231, and the first foolproofing column 224 and the second foolproofing column 225 are inserted into the corresponding first foolproofing holes 231. There is one first foolproofing column 224 and one second foolproofing column 225, and the air inlet frame 222 can be installed on the bracket 21 at a fixed angle through the mutual cooperation of the first foolproofing column 224 and one of the first foolproofing holes 231, and the air outlet frame 223 can be installed on the bracket 21 at a fixed angle through the mutual cooperation of the second foolproofing column 225 and another first foolproofing hole 231, thereby achieving the purpose of foolproofing.

[0079] Of course, the first anti-foolproofing column 224 and the second anti-foolproofing column 225 can also be set on the fan 23, and corresponding anti-foolproofing holes can be set on the air inlet frame 222 and the air outlet frame 223. This application does not limit this and can be specifically set according to the actual processing difficulty.

[0080] In some embodiments, the fan frame 22 and the fan 23 are connected by adhesive nails 226 , and the adhesive nails 226 can achieve vibration reduction while achieving fixed connection between the fan frame 22 and the fan 23 .

[0081] A sound-absorbing sponge 26 is provided between the fan frame 22 and the bracket 21, which can reduce noise while achieving secondary vibration reduction of the fan 23. The sound-absorbing sponge 26 can be arranged on the outside of the fan frame 22, or on the inside of the bracket 21, so that the sound-absorbing sponge 26 can be located between the fan frame 22 and the bracket 21, and specifically, the sound-absorbing sponge 26 can be fixed by bonding.

[0082] The fan frame 22 is connected to the bracket 21 by fixing nails 25. In specific implementation, during installation, the fan frame 22 and the bracket 21 can be initially fixed by I-shaped nails 24, and then finally fixed by fixing nails 25.

[0083] Among them, refer to Figures 14 to 16As shown in the figure, the fixing nail 25 includes a first rotating column 251, a second rotating column 253 and a plug pin 255. Both the first rotating column 251 and the second rotating column 253 are sleeved outside the plug pin 255. The first rotating column 251 can rotate relative to the plug pin 255, and the second rotating column 253 can slide relative to the plug pin 255. A first cutting surface 252 is formed on the outer side surface of the first rotating column 251, and a second cutting surface 254 is formed on the outer side surface of the second rotating column 253. A fitting groove adapted to the cross-section of the second rotating column 253 is formed inside the first rotating column 251. When the first cutting surface 252 and the second cutting surface 254 are not parallel, the first rotating column 251 and the second rotating column 253 are in abutting fit with each other along the axial direction of the plug pin 255. When the first cutting surface 252 and the second cutting surface 254 are parallel, the second rotating column 253 can slide along the axial direction of the plug pin 255 to be inserted into the fitting groove. That is to say, after rotating the first rotating column 251, the plug pin 255 can be exposed, and then the fan frame 22 and the bracket 21 can be locked through the plug pin 255, realizing the tool-free installation between the fan frame 22 and the bracket 21. Specifically, an interference fit exists between the plug pin 255 and both the fan frame 22 and the bracket 21, which can ensure the connection strength.

[0084] During specific implementation, a plug hole 216 can be formed on the side wall of the bracket 21. The plug pin 255 can be inserted into the plug hole 216, and then the fixing nail 25 can be locked and fixed on the bracket 21.
