[0076] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention.

[0077] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0078] Next, a heat dissipation device provided in an embodiment of the present invention will be introduced in detail. The heat dissipation device is used for heat dissipation of a blade server. The heat dissipation device specifically includes a chassis 1, a heat dissipation mechanism 2, a flow guiding component 04, and a water cooling mechanism 3. Please refer to Figure 1 , Figure 4 , Figure 5 .

[0079] The chassis 1 is provided with at least two installation areas 01 for placing the blade mainboards 5 of the blade server. The number and size of the installation areas 01 can be determined according to the design requirements of the actual blade server.

[0080] A first flow gap 02 is formed between the top of the installation area 01 and the inner wall of the chassis 1, and a second flow gap 03 is formed between the bottom of the installation area 01 and the inner wall of the chassis 1. Here, the top and bottom are in terms of the Figure 5 orientation. The top is the upper side direction of Figure 5 , and the bottom is the lower side direction of Figure 5 . Cooling air is introduced into the first flow gap 02 and the second flow gap 03 for cooling the top and bottom of the blade mainboard 5.

[0081] A flow guiding component 04 is arranged between two adjacent installation areas 01 for guiding the cooling air to the circumferential direction of the blade mainboard 5 for heat dissipation. Here, the circumferential direction corresponds to the Figure 1 left and right sides and / or the front and back sides. The first flow gap 02 and the second flow gap 03 are both connected to the spaces corresponding to a plurality of flow guiding components 04, that is, the cooling air flows in the first flow gap 02, the second flow gap 03, and the spaces corresponding to the flow guiding components 04 to dissipate heat from the blade mainboard 5.

[0082] In this embodiment, the flow guiding component 04 is mainly used to smoothly and reliably introduce the cooling air into the circumferential direction of the blade mainboard 5. Through the guiding action of the flow guiding component 04, the flow rate of the cooling air is increased, and the heat dissipation efficiency is improved. Specifically, the flow guiding component 04 may include components such as a flow guiding plate and a flow guiding block that can guide the flow through shapes such as an inclined surface, an arc surface, or a curved surface, and can realize changing the direction of the cooling air and guiding the air flow.

[0083] It should be noted that the first flow gap 02 and the second flow gap 03 correspond to the top and bottom of the blade main board 5, and the flow guiding component 04 corresponds to the left side / right side of the blade main board 5. At least the heat on the left and right sides of the blade main board 5 can be taken away by the flow guiding component 04 for heat dissipation. If there are also gaps between the front and rear sides of the blade main board 5 and the inner wall of the chassis 1, due to the flow of air, the front and rear sides of the blade main board 5 will also pass through the cooling air to achieve the heat dissipation of the front and rear sides of the blade main board 5. Through the circulation of the cooling air in all directions of the blade main board 5, the heat generated by the blade main board 5 can flow fully, ensuring the overall heat dissipation effect of the blade server.

[0084] The heat dissipation mechanism 2 is connected to the first flow gap 02 or the second flow gap 03, and is used to provide cooling air. Through the circulation of the cooling air in the first flow gap 02, the second flow gap 03, and the spaces corresponding to several flow guiding components 04, the top, bottom, and circumferential direction of the blade main board 5 are cooled, ensuring effective heat dissipation in multiple directions of the blade main board 5.

[0085] The water cooling mechanism 3 is located at the end of the flow guiding component 04, and is used to absorb the heat obtained after the heat exchange of the cooling air and send it outside the chassis 1, so that the heat in multiple directions of the blade main board 5 is taken out of the machine, ensuring the reliable heat dissipation of the blade server and the safe and reliable operating performance of the server. The water cooling mechanism 3 can specifically absorb heat through a cooling medium, such as cooling water.

[0086] Taking a specific embodiment as an example, if the heat dissipation mechanism 2 is connected to the first flow gap 02, the flow guiding component 04 is used to guide the cooling air from the first flow gap 02 to the circumferential direction of the blade main board 5, and further guide it to the second flow gap 03. At this time, the end of the flow guiding path of the corresponding flow guiding component 04 is at the position of the second flow gap 03. The water cooling mechanism 3 is used to absorb the heated cooling air in the second flow gap 03 by water cooling and discharge the heat outside the machine. The heat dissipation of the blade server is completed through the cooperation of air cooling and water cooling.

[0087] Taking another specific embodiment as an example, if the heat dissipation mechanism 2 is connected to the second flow gap 03, the flow guiding component 04 is used to guide the cooling air from the second flow gap 03 to the first flow gap 02 through the flow guiding component 04. Then, the end of the flow guiding path of the corresponding flow guiding component 04 is at the position of the first flow gap 02. The water cooling mechanism 3 is used to absorb the heated cooling air in the first flow gap 02 by water cooling and discharge the heat outside the machine. The heat dissipation of the blade server is completed through the cooperation of air cooling and water cooling.

[0088] The above heat dissipation device enables the circumferential, top, and bottom of the blade main board 5 to have circulating cooling air through the circulation of the first circulation gap 02, the second circulation gap 03, and the space corresponding to the flow guiding component 04. Through the full flow of the cooling air at various positions of the blade server, the blade server is effectively cooled, ensuring the stable and reliable operation performance of the server.

[0089] On the basis of the above embodiment, the flow guiding component 04 includes flow guiding plates 210. A plurality of flow guiding plates 210 are arranged in sequence along the height direction of the installation area 01. Please refer to Figure 2 , Figure 3 . The height direction of the installation area 01 is the Figure 2 up and down direction. The plurality of flow guiding plates 210 can be evenly arranged, or can be flexibly arranged according to the actual situation.

[0090] Taking a specific embodiment as an example, if the heat dissipation mechanism 2 is connected to the first circulation gap 02, the end close to the first circulation gap 02 is the first end of the flow guiding component 04, and the end far from the first circulation gap 02 is the second end of the flow guiding component 04. The slope of the flow guiding plate 210 at the first end of the flow guiding component 04 is greater than the slope of the flow guiding plate 210 at the second end of the flow guiding component 04. The slope here can be regarded as the angle between the flow guiding plate 210 and the horizontal plane. By setting the slope of the flow guiding plate 210 far from the first circulation gap 02 to be smaller, the air flow can have a greater flow velocity when being guided to be close to the second circulation gap 03, enabling the air flow in the space corresponding to the flow guiding component 04 to reliably flow to the second circulation gap 03, and then the heat of the cooling air after heat exchange through the flow guiding component 04 is effectively absorbed by the water cooling of the water cooling mechanism 3 and discharged outside the machine.

[0091] Taking a specific embodiment as an example, if the heat dissipation mechanism 2 is connected to the first circulation gap 02, the end close to the first circulation gap 02 is the first end of the flow guiding component 04, and the end far from the first circulation gap 02 is the second end of the flow guiding component 04. The number of flow guiding plates 210 at the first end of the flow guiding component 04 is less than the number of flow guiding plates 210 at the second end of the flow guiding component 04, so that the guiding effect at the second end of the flow guiding component 04 is stronger than that at the first end of the flow guiding component 04, enabling the cooling air in the space corresponding to the flow guiding component 04 to reliably flow into the second circulation gap 03, and then being water-cooled by the water cooling mechanism 3 to ensure the cooling effect.

[0092] Taking a specific embodiment as an example, if the heat dissipation mechanism 2 is connected to the first circulation gap 02, the end close to the first circulation gap 02 is the first end of the flow guiding component 04, and the end far from the first circulation gap 02 is the second end of the flow guiding component 04. The number and slope of the flow guiding plates 210 corresponding to the first end and the second end of the flow guiding component 04 are both kept consistent, enabling the cooling air to enter the space corresponding to the flow guiding component 04 from the first circulation gap 02 and evenly guiding the cooling air to ensure the cooling effect on the circumference of the blade main board 5.

[0093] The flow deflector 210 is arranged to incline downward, and the extension surfaces of the flow deflector 210 between two adjacent installation areas 01 have intersecting intersection points. Please refer to Figure 4 , Figure 5 , Figure 6 , the flow deflectors 210 are arranged staggeredly between two adjacent installation areas 01. The staggering here does not mean intersection. Specifically, two adjacent flow deflectors 210 have a height difference in height and are relatively inclined, so that the cooling air is guided from top to bottom through the flow deflectors 210 to the right side of a certain blade main board 5 and the left side of another blade main board 5 adjacent to this blade main board 5 at the same time. The cooling effects of the corresponding two sides of two blade main boards 5 are realized simultaneously through multiple flow deflectors 210 in one installation area 01.

[0094] Furthermore, the extension surfaces of two adjacent flow deflectors 210 between two adjacent installation areas 01 have intersecting intersection points. Among them, the extension surface of the flow deflector 210 closer to the other blade main board 5 extends towards a certain blade main board 5 to guide the cooling air to the right side of a certain blade main board 5; the extension surface of the flow deflector 210 closer to a certain blade main board 5 extends towards the other blade main board 5 to guide the cooling air to the left side of the other blade main board 5. Through this setting method, the cooling air can be evenly and stably guided to the corresponding sides of two adjacent blade main boards 5 to ensure the cooling effect of the blade main board 5.

[0095] On the basis of any of the above embodiments, please refer to Figure 6 , a side plate 209 is fixedly installed in the chassis 1, and an installation area 01 is formed between two adjacent side plates 209. The blade main board 5 is located between two adjacent side plates 209, and the side plate 209 can be arranged on one side or both sides of the chassis 1. One side here refers to the front side or the rear side of the chassis 1, and both sides refer to the front and rear sides of the chassis 1. The front and rear here are in terms of the Figure 6 orientation.

[0096] Multiple flow deflectors 210 are arranged in sequence along the height direction of the side plate 209. The height direction of the side plate 209 is the same as the height direction of the blade main board 5, and each end of each flow deflector 210 is connected to the side plate 209. The side plate 209 provides space for the installation of the flow deflector 210, and the flow deflector 210 is fixed on the side plate 209 to provide a better flow guiding effect during the heat dissipation operation.

[0097] Each flow deflector 210 has two ends, and the two ends can be respectively connected to two side plates 209; or only one end is connected to one side plate 209, and the other end is connected to the chassis 1; or only one end is connected to one side plate 209, and the other end is not connected to a component.

[0098] In this embodiment, the side plate 209 is set to be detachably connected to the chassis 1, and there is no limitation on whether the flow guide plate 210 and the side plate 209 are detachably connected or integrally formed.

[0099] Based on any of the above embodiments, along the height direction of the installation area 01, the angles of a plurality of flow guide plates 210 located between two adjacent installation areas 01 are alternately arranged to form at least one S-shaped flow guide path. Through the S-shaped flow guide path, the cooling air can flow sufficiently between two adjacent blade mainboards 5, ensuring the cooling effect of the blade mainboard 5 and further ensuring the safe and reliable operation of the blade server. When two or more S-shaped flow guide paths are formed, the two or more S-shaped flow guide paths can be arranged continuously or at intervals, without limitation.

[0100] The above-mentioned alternate angle setting specifically means that, for example, if three flow guide plates 210 are arranged in sequence along the height direction of the installation area 01, the inclination angles of the first flow guide plate 210 and the third flow guide plate 210 are the same, and the second flow guide plate 210 is located between the first flow guide plate 210 and the third flow guide plate 210 and forms a different inclination angle. Please refer to Figure 5 The above-mentioned different inclination angles are based on the same reference plane. For example, the included angles formed by the three flow guide plates 210 based on the same horizontal plane are the above-mentioned inclination angles.

[0101] Based on any of the above embodiments, a plurality of flow guide plates 210 located between two adjacent installation areas 01 form at least one Z-shaped flow guide path. Through the Z-shaped flow guide path, the cooling air can flow sufficiently between two adjacent blade mainboards 5, ensuring the cooling effect of the blade mainboard 5 and further ensuring the safe and reliable operation of the blade server. When two or more Z-shaped flow guide paths are formed, the two or more Z-shaped flow guide paths can be arranged continuously or at intervals, without limitation.

[0102] Based on any of the above embodiments, a plurality of flow guide plates 210 located between two adjacent installation areas 01 form at least one Z-shaped flow guide path and at least one S-shaped flow guide path. Through the settings of the Z-shaped flow guide path and the S-shaped flow guide path, the flow effect of the cooling air between two adjacent blade mainboards 5 is ensured, the cooling effect of the blade mainboard 5 is ensured, and the safe and reliable operation of the blade server is further ensured. The at least one Z-shaped flow guide path and the at least one S-shaped flow guide path can be arranged alternately or continuously. The continuous arrangement here is, for example, setting three Z-shaped flow guide paths and then setting three S-shaped flow guide paths. The alternate arrangement here means setting one S-shaped flow guide path and then setting one Z-shaped flow guide path to form an alternation.

[0103] Based on any of the above embodiments, an upper air plate 202 and a lower air plate 203 are arranged in the chassis 1. Please refer to Figure 4 、 Figure 5 、Figure 7 。

[0104] A first flow gap 02 is formed between the upper air plate 202 and the inner wall of the chassis 1, and a second flow gap 03 is formed between the lower air plate 203 and the inner wall of the chassis 1. A plurality of upper air plates 202 and a plurality of lower air plates 203 are arranged oppositely to form at least two corresponding installation areas 01.

[0105] Specifically, if one upper air plate 202 and one lower air plate 203 are provided, please refer to Figure 4 , both the upper air plate 202 and the lower air plate 203 include a main body. One side of the main body is connected to the inner wall of the chassis 1, and the other side is connected to a plurality of U-shaped support frames. The U-shaped support frames are the components for supporting and installing the blade main board 5. The support frames of the upper air plate 202 and the support frames of the lower air plate 203 correspond to form at least two installation areas 01 to form reliable support for at least two blade main boards 5. A gap is formed between two adjacent U-shaped support frames, and this gap is the opening for the cooling air to enter the flow guiding component 04.

[0106] If there are two or more upper air plates 202 and lower air plates 203, specifically, the upper air plates 202 and the lower air plates 203 are U-shaped support frames arranged at intervals along the length direction of the chassis 1. Then, a plurality of U-shaped support frames are connected and fixed to the inner wall of the chassis 1 to form a fixation. The support frames of the upper air plate 202 and the support frames of the lower air plate 203 correspond to form at least two installation areas 01.

[0107] Further, a plurality of upper air vents 207 are provided on the upper air plate 202, such as Figure 4 , the upper air vents 207 are the gaps formed between two adjacent support frames of the upper air plate 202; a plurality of lower air vents 208 corresponding to the upper air vents 207 are provided on the lower air plate 203, and the lower air vents 208 are the gaps formed between two adjacent support frames of the lower air plate 203.

[0108] The upper air vents 207 and the lower air vents 208 are respectively located at the starting end and the ending end of the flow guiding path of the flow guiding component 04. Taking the heat dissipation mechanism 2 communicating with the first flow gap 02 as an example, the upper air vents 207 are arranged at the upper end of the flow guiding component 04, and the lower air vents 208 are arranged at the lower end of the flow guiding component 04. Here, the upper end and the lower end correspond to the starting end and the ending end of the flow guiding path.

[0109] In this embodiment, the sizes of the upper air vents 207 and the lower air vents 208 can be set to be the same or different. For example, the opening of the lower air vent 208 is set larger so that the cooling air after heat and cold exchange can quickly flow to contact the water cooling mechanism 3 to take the heat out of the machine.

[0110] On the basis of any of the above embodiments, please refer to Figure 4, the heat dissipation mechanism 2 includes a housing 201 located outside the chassis 1. A fan 205 for providing cooling air is provided inside the housing 201. The air flow path of the fan 205 is communicated with the first flow gap 02. Cooling air is sent into the first flow gap 02 through the fan 205, and then the cooling air is guided to the second flow gap 03 through the guiding component 04, and then cooled by the water cooling mechanism 3, so as to realize the heat dissipation at the top, bottom and circumferential direction of the blade main board 5 and ensure the heat dissipation effect of the blade main board 5.

[0111] In this embodiment, the housing 201 is detachably connected to the chassis 1. For example, the housing 201 is arranged to be openable and closable, so as to facilitate the installation and disassembly of the fan 205 inside the housing 201.

[0112] A guiding member 206 is arranged inside the housing 201, or a guiding member 206 is arranged on the outer wall of the chassis 1, or guiding members 206 are arranged both inside the housing 201 and on the outer wall of the chassis 1. In any of the above embodiments, the guiding member 206 can be used to guide the air flow of the fan 205 to the first flow gap 02, ensuring that the cooling air of the fan 205 can flow smoothly and reliably into the first flow gap 02, so as to flow from the top of the blade main board 5, then through the circumferential direction of the blade main board 5 to the bottom, and dissipate heat in all directions.

[0113] The guiding member 206 can specifically be an inclined panel. As Figure 4 shown, when the housing 201 is arranged on the side of the chassis 1, the guiding member 206 can guide the cooling air obliquely upward from the housing 201 to the first connection port 6 inside the chassis 1. After passing through the first connection port 6, the cooling air flows into the first flow gap 02.

[0114] The guiding member 206 can also be set as a plate with an arc. For example, the wall surface of the chassis 1 corresponding to the position of the first connection port 6 is provided with an arc-shaped guiding port, so as to facilitate the smooth entry of the cooling air into the first flow gap 02.

[0115] Please refer to Figure 4 , a fixed cylinder 204 is fixedly installed inside the housing 201. Both ends of the fixed cylinder 204 are open. One end is used to cooperate with the first dust filter net 211 arranged on the housing 201, and the other end is used to provide a space for the internal circulation of the housing 201, so that the cooling air of the fan 205 can be sent from the housing 201 to the inside of the chassis 1 through the guiding member 206. The fan 205 is fixedly installed inside the fixed cylinder 204. The fixed cylinder 204 can provide a certain protection function to avoid the damage of the fan 205 to the housing 201 and ensure the service life of the housing 201; in addition, through the setting of the fixed cylinder 204, the cooling air of the fan 205 is concentrated in the cylinder body and then guided to the chassis 1, ensuring the conveying effect of the cooling air.

[0116] Based on any of the above embodiments, the water cooling mechanism 3 includes: an outer shell 301, a first circulation pipe 305, a second circulation pipe 307. Please refer toFigure 7 , Figure 8 , Figure 4 。

[0117] The housing 301 is connected to the side of the chassis 1 and is disposed opposite to the heat dissipation mechanism 2. The heat dissipation air sent by the heat dissipation mechanism 2 flows through the chassis 1 and then the heat is exported to the outside of the machine through the water cooling mechanism 3 to realize the heat dissipation process.

[0118] The housing 301 can be set to be detachably connected to the chassis 1, and the detachable connection can be, for example, connected by fasteners, rotatably connected by rotating parts, etc.

[0119] The first flow pipe 305 is disposed in the housing 301 and is communicated with the second flow pipe 307 disposed in the chassis 1. Coolant is introduced into the first flow pipe 305 and the second flow pipe 307, and the heat of the heat dissipation air after heat and cold exchange is taken out of the machine through the flow of the coolant to ensure the effective heat dissipation of the blade main board 5. The coolant here can be in a circulating flow or a one-way flow. The one-way flow is specifically the way of entering through the second flow pipe 307 and flowing out of the machine through the first flow pipe 305; the circulating flow is specifically that after the coolant in the second flow pipe 307 completes heat and cold exchange, it can be reused after passing through the first flow pipe 305.

[0120] In addition, the second flow pipe 307 is disposed in the second flow gap 03, and the second flow gap 03 is substantially the gap inside the lower air plate 203. When the heat dissipation air flows to the surface of the second flow pipe 307, part of the heat of the second flow pipe 307 can also be blown away, further ensuring the water cooling effect of the second flow pipe 307. Through the water cooling and air cooling methods, the reliable heat dissipation effect at the bottom of the blade main board 5 is ensured.

[0121] To improve the heat dissipation efficiency, both the first flow pipe 305 and the second flow pipe 307 can be set to be serpentine, S-shaped, loop-shaped, W-shaped, etc. By increasing the contact area between the first flow pipe 305, the second flow pipe 307 and the bottom of the blade main board 5, the heat of the heat dissipation air after heat and cold exchange can be quickly taken out of the machine to ensure the heat dissipation effect.

[0122] On the basis of any of the above embodiments, the water cooling mechanism 3 further includes a water tank 302 fixed to the housing 301 and a circulation pump 304 fixed to the housing 301. Please refer to Figure 8 。

[0123] The water tank 302 is arranged between the first end of the second circulation pipe 307 and the second end of the first circulation pipe 305; the first end of the circulation pump 304 is connected to the first end of the first circulation pipe 305, and the other end of the circulation pump 304 is connected to the second end of the second circulation pipe 307. Cooling water is stored in the water tank 302. The cooling water in the water tank 302 is pumped by the circulation pump 304 so that the cooling water passes through the first circulation pipe 305 and the second circulation pipe 307. Among them, the cooling air enters the inside of the lower air plate 203 through the lower air inlet 208 and cooperates with the second circulation pipe 307 to dissipate heat from the bottom of the blade main board 5, and the first circulation pipe 305 can dissipate heat from the side wall of the chassis 1. At the same time, when the cooling air passes through the surfaces of the first circulation pipe 305 and the second circulation pipe 307, it can take away a certain amount of heat from the cooling water inside the circulation pipe, making the water-cooling heat dissipation effect better. At the same time, the heat dissipation effect of the blade server is further improved, making the operation of the blade server more stable.

[0124] In this embodiment, the cooling water in the water tank 302 can circulate between the first circulation pipe 305 and the second circulation pipe 307. Water-cooled components can be arranged in the water tank 302 to maintain the coldness of the cooling water and ensure the cooling effect of the cooling water pumped by the circulation pump 304.

[0125] On the basis of any of the above embodiments, the heat dissipation device further includes a docking mechanism 4 for detachably connecting the water-cooling mechanism 3 and the chassis 1. The docking mechanism 4 includes a fixing frame 401, a receiving block 404, and a plug-in block 402. Please refer to Figure 1 、 Figure 9 。

[0126] At least one fixing frame 401 is arranged on the side wall of the chassis 1, and at least one receiving block 404 is arranged on the side wall of the chassis 1. The number of the fixing frame 401 and the receiving block 404 here can be set according to the actual installation requirements of the water-cooling mechanism 3.

[0127] For example, one group, two groups, three groups or four groups can be set. If two groups are set, that is, the docking mechanism 4 is symmetrically arranged on both sides of the outer shell 301.

[0128] A plug-in space is formed between a receiving block 404 and its corresponding fixing frame 401. The plug-in space here is formed by the components fixed on the chassis 1. The plug-in block 402 is arranged on the outer shell 301 of the water-cooling mechanism 3, and the installation of the water-cooling mechanism 3 and the chassis 1 is realized through the plug-in block 402.

[0129] Specifically, when the plug-in block 402 extends into the plug-in space, the water-cooling mechanism 3 can be installed on the chassis 1; when the plug-in block 402 is removed from the plug-in space, the water-cooling mechanism 3 can be detached from the chassis 1.

[0130] In this embodiment, the insertion space can have multiple directions, such as horizontal and / or vertical. Through the insertion of the insertion block 402, the portable disassembly and assembly of the water cooling mechanism 3 relative to the chassis 1 can be realized. During transportation and transfer, the water cooling mechanism 3 can be removed for transportation; or when the water cooling mechanism 3 needs to be overhauled, it can be removed from the chassis 1. In either case, the insertion block 402 can facilitate the insertion and extraction with the insertion space, be easy to operate and ensure the stability and reliability during insertion.

[0131] Based on any of the above embodiments, please refer to Figure 4 , Figure 6 , Figure 7 , the position of the second flow gap 03 close to the outer shell 301 is the second connection port 7. The second flow pipe 307 passes through the second connection port 7 and communicates with the first flow pipe 305 inside the outer shell 301. When the water cooling mechanism 3 needs to be disassembled or installed, the second flow pipe 307 can enter or exit the chassis 1 from the second flow gap 03.

[0132] The insertion direction of the insertion block 402 is parallel to the opening direction of the second connection port 7. When the insertion block 402 is removed from the insertion space, the second flow pipe 307 is removed from the second connection port 7. The water cooling mechanism 3 can be manually removed from the chassis 1 without auxiliary tools, which is simple and convenient to operate and improves the applicability of the device.

[0133] It should be noted that the cooling air at the lower air outlet 208 contacts the second flow pipe 307 for water cooling. The second connection port 7 is just an opening on the lower air plate 203 and does not affect the operation of the second flow pipe 307. As long as the opening here can facilitate the movement of the second flow pipe 307 in and out, it is sufficient.

[0134] Based on any of the above embodiments, the docking mechanism 4 further includes: a positioning rod 405, an elastic member 407, and a limiting plate 408. Please refer to Figure 9 .

[0135] One end of the positioning rod 405 is provided with a pulling block 406 located outside the fixing frame 401. The other end of the positioning rod 405 can move to extend into or out of the insertion space; the insertion block 402 is provided with a jack 403. The positioning rod 405 can be inserted into the jack 403 to lock the water cooling mechanism 3. The axial direction of the jack 403 is the same as the moving direction of the positioning rod 405, and the insertion direction of the insertion block 402 is perpendicular to the moving direction of the positioning rod 405.

[0136] The elastic member 407 is sleeved on the positioning rod 405 and is located within the frame of the fixing frame 401.

[0137] The limiting plate 408 is arranged on the positioning rod 405, specifically, it can be arranged on the part of the positioning rod 405 located inside the fixing frame 401. The opening on the fixing frame 401 corresponding to the positioning rod 405 is smaller than the size of the limiting plate 408, and the situation where the positioning rod 405 is directly pulled off from the fixing frame 401 is limited by the limiting plate 408. The two ends of the elastic member 407 respectively correspond to the inner wall of the fixing frame 401 and the limiting plate 408. The so-called "respectively corresponding" here means that they can be respectively connected, or respectively abutted, or respectively connected and abutted. No matter which way, the elastic member 407 can be compressed to contact and limit the plug-in block 402, and the elastic member 407 can be reset to limit the movement effect of the plug-in block 402.

[0138] When the specific docking mechanism 4 is in use and the water cooling mechanism 3 needs to be disassembled and maintained, the operator can pull up the pulling block 406 so that the positioning rod 405 can be extracted from the jack 403 in the plug-in block 402. At this time, the plug-in block 402 loses the limit of the positioning rod 405, and the staff can pull the outer shell 301 to the left, so that the water cooling mechanism 3 is detached from the chassis 1, which is convenient for quickly maintaining the water cooling mechanism 3 and further improves the practicability of the heat dissipation device.

[0139] Based on any of the above embodiments, please refer to Figure 4 , a through hole is provided on the housing 201, and a first dust filter screen 211 is arranged inside the through hole. The first dust filter screen 211 is detachably connected to the housing 201, which can prevent dust from being brought into the inside of the chassis 1 and ensure the safe and reliable operation of the blade server.

[0140] Please refer to Figure 8 , an air outlet 303 is provided on the outer shell 301, and a second dust filter screen 306 is fixedly installed inside the air outlet 303. The outer shell 301 is detachably connected to the second dust filter screen 306 to prevent dust from entering the inside of the outer shell 301.

[0141] Specifically, the detachable operation of the first dust filter screen 211 and the second dust filter screen 306 is realized through the disassembly and assembly mechanism 8.

[0142] The disassembly and assembly mechanism 8 is arranged on the housing 201 and / or the outer shell 301. The disassembly and assembly mechanism 8 is used to connect or disconnect from the first dust filter screen 211 and the second dust filter screen 306 to realize the assembly and disassembly of the first dust filter screen 211 or the second dust filter screen 306.

[0143] For the need to facilitate the disassembly of the first dust filter screen 211 and the second dust filter screen 306, two disassembly and assembly mechanisms 8 can be provided to improve the overall maintainability of the heat dissipation device and its applicability. When the blade server has been used for a long time and it is necessary to disassemble and replace or disassemble and maintain the filter screen, the first dust filter screen 211 and the second dust filter screen 306 can be conveniently disassembled and assembled through the disassembly and assembly mechanism 8.

[0144] Based on any of the above embodiments, the disassembly and assembly mechanism 8 includes a clamping plate 801, a positioning post 802, and a push plate 809. Please refer to Figures 10 - 13 .

[0145] At least one clamping plate 801 is movably arranged in the housing 201, and the clamping plate 801 can be provided with one, two or more. For example, when four clamping plates 801 are provided, the disassembly and assembly mechanism 8 is correspondingly arranged around the first dust filter screen 211 to ensure the reliability of the first dust filter screen 211 when it is not disassembled.

[0146] The positioning post 802 is arranged on the first dust filter screen 211 for clamping the clamping plate 801, and the clamping plate 801 can move to clamp the positioning post 802 or release the clamping with the positioning post 802.

[0147] The push plate 809 is arranged on the clamping plate 801. The push plate 809 is used to drive the clamping plate 801 to move so that the positioning post 802 and the clamping plate 801 are clamped or the clamping is released. When the positioning post 802 and the clamping plate 801 are clamped, the first dust filter screen 211 is correspondingly arranged on the housing 201; when the positioning post 802 and the clamping plate 801 are released from the clamping, the first dust filter screen 211 is removed from the housing 201.

[0148] In this embodiment, two positioning posts 802 can be provided to ensure the reliability of the first dust filter screen 211 in the clamped state.

[0149] Based on any of the above embodiments, please refer to Figures 10 - 13 , an arc-shaped clamping groove 808 is arranged on the clamping plate 801, and the arc-shaped clamping groove 808 is used for clamping the positioning post 802. The push plate 809 driving the clamping plate 801 to move can make the arc-shaped clamping groove 808 clamp or release the clamping of the positioning post 802.

[0150] The clamping plate 801 is provided with a guide hole 806, and a return spring 807 is arranged in the guide hole 806. One end of the return spring 807 is connected with a pushing member, and the pushing member is fixed to the housing 201. The clamping plate 801 can move along the length direction of the guide hole 806 so that the return spring 807 is in a compressed state or a reset state in the guide hole 806.

[0151] The driving member specifically includes a guide block 804 and a limit block 805 fixedly connected to the housing 201, and the guide block 804 and the limit block 805 can be integrally formed. Both the guide block 804 and the limit block 805 are arranged in the guide hole 806 and the limit block 805 extends out of the guide hole 806. By arranging the limit block 805, the clamping plate 801 can be prevented from separating from the guide block 804.

[0152] When the clamping plate 801 moves to compress the return spring 807, the arc-shaped card slot 808 and the positioning post 802 are disengaged, and the first dust filter net 211 can be removed; when the clamping plate 801 moves to make the return spring 807 in a reset state, the arc-shaped card slot 808 and the positioning post 802 are engaged, and the first dust filter net 211 is installed on the housing 201.

[0153] After the blade server is used for a long time, the first dust filter net 211 will be blocked due to intercepting a large amount of dust and fluff. At this time, the staff can push the push plate 809 in the direction away from the first dust filter net 211, so that the push plate 809 moves along the guide block 804, and the positioning post 802 disengages from the inside of the card slot 808. At this time, the staff can directly remove the first dust filter net 211 from the embedding slot 803 of the housing 201 for cleaning, avoiding the influence of dust blockage on the heat dissipation effect of air cooling; after the cleaning is completed, the first dust filter net 211 is placed into the inside of the embedding slot 803 and the push plate 809 is released, so that the clamping plate 801 moves under the action of the return spring 807, and the arc-shaped card slot 808 is docked with the positioning post 802, realizing the rapid installation and fixation of the first dust filter net 211, and enabling rapid cleaning without shutting down the machine.

[0154] In addition to the above heat dissipation device, the present invention also provides a heat dissipation method applied to the heat dissipation device in any of the above embodiments. The heat dissipation method includes:

[0155] Controlling the operation of the heat dissipation mechanism 2 to introduce heat dissipation air into the first flow gap 02 or the second flow gap 03, so that the heat dissipation air circulates between the first flow gap 02, the diversion component 04, and the second flow gap 03, to reliably dissipate heat from the top, bottom, and circumferential direction of the blade main board 5.

[0156] Controlling the operation of the water cooling mechanism 3 to export the heat dissipation air at the end of the diversion path of the diversion component 04 from the chassis 1, that is, sending the heat dissipation air sent into the chassis 1 by the heat dissipation mechanism 2 out of the chassis 1 after completing the heat exchange, completing the heat dissipation process, ensuring the full flow of multi-directional heat of the blade main board 5, ensuring the reliable effectiveness of heat dissipation, and ensuring the operation safety and reliability of the blade server.

[0157] More specifically, the steps of the heat dissipation method are as follows:

[0158] S1. Start the fan 205 to blow air into the first flow gap 02 inside the upper air plate 202. Its cooling air enters between the two blade main boards 5 through the upper air outlet 207. The flow guide plate 210 between the two blade main boards 5 can accelerate the flow rate of the cooling air, prevent the cooling air from staying between the two blade main boards 5 for a long time, and enable its heat to flow away quickly.

[0159] S2. Start the circulation pump 304 to extract the cooling water inside the water tank 302, so that the cooling water passes through the first flow pipe 305 and the second flow pipe 307. When the cooling air enters the second flow gap 03 inside the lower air plate 203 from the lower air outlet 208 and cooperates with the second flow pipe 307 to dissipate heat from the bottom of the blade main board 5, the first flow pipe 305 can dissipate heat from the side wall of the chassis 1. At the same time, when the cooling air passes through the first flow pipe 305 and the second flow pipe 307, it can take away a certain amount of heat from the cooling water inside the flow pipe, making the water-cooled heat dissipation effect better.

[0160] S3. The cooling air passes through the upper air plate 202, between the two blade main boards 5 and the lower air plate 203, which can achieve comprehensive heat dissipation of the blade main board 5 in all directions (up, down, left, and right). At the same time, the cooling air finally discharges from the air outlet 303 of the outer shell 301 and takes away part of the heat of the first flow pipe 305 inside the outer shell 301.

[0161] In addition to the heat dissipation devices and heat dissipation methods provided in the above various embodiments, the present invention also provides a blade server including the heat dissipation device of any one of the above embodiments. The blade server further includes at least a plurality of blade main boards 5, and the plurality of blade main boards 5 are arranged in the corresponding installation area 01 of the heat dissipation device. Other structures of the blade server can refer to the related art and will not be elaborated here.

[0162] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0163] The above has introduced in detail a heat dissipation device, a heat dissipation method and a blade server provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
