Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this utility model are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the protection scope of this utility model. The accompanying drawings of the embodiments of this utility model are only for illustrating relative positional relationships and do not represent actual proportions.

[0025] It should be noted that specific details are set forth in the following description to facilitate understanding of this utility model. However, this utility model can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] With the rapid development of cloud computing and artificial intelligence, the research and use of high-performance servers are attracting much attention. However, the more powerful the performance and processing capacity of a server is, the higher the heat generated by the internal components of the server is. To ensure the reliable operation of the server, at present, a fan is mainly arranged inside the case of the server to dissipate heat from the heat-generating components. However, in the prior art, the fan is mostly mounted on a fan bracket and can only dissipate heat from a single heat-generating component. When there are multiple heat-generating components inside the case, the number of fans and fan brackets needs to be additionally increased to meet the heat dissipation requirements of the server, which will additionally occupy the internal space of the server and increase the heat dissipation cost of the server.

[0027] Therefore, the heat dissipation device provided by the utility model can simultaneously install multiple heat-generating components, and the multiple air outlets of the heat dissipation device are arranged in one-to-one correspondence with the multiple heat-generating components, so that the internal space of the server occupied by the heat dissipation device is reduced, and the heat dissipation cost of the server is effectively reduced while meeting the heat dissipation requirements of the server. In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0028] Reference Figure 1 , Figure 1 A structural schematic view of the heat dissipation device provided by the utility model. The heat dissipation device is arranged in the case 01 of the server, and additionally, reference is made to Figure 1 and Figure 2 , Figure 2 A partial structural schematic view of the heat dissipation device provided by the utility model. The heat dissipation device comprises a fan 1, a mounting groove 2 and an air guide structure 3. As shown in Figure 1 , the groove bottom of the mounting groove 2 is provided with an air inlet hole 21, the fan 1 is arranged in the mounting groove 2, the air inlet of the fan 1 is opposite to the air inlet hole 21 of the groove bottom of the mounting groove 2, and the air outlet of the fan 1 is opposite to the slot of the mounting groove 2. In this way, in the working process of the heat dissipation device, the airflow can enter the fan 1 through the air inlet hole 21 of the groove bottom, and then be blown into the case of the server through the slot of the mounting groove 2 by the air outlet of the fan 1.

[0029] As shown in Figure 2 , the air guide structure 3 is located outside the mounting groove 2 and is arranged at the slot of the mounting groove 2. At the same time, the air guide structure 3 is used to separate the slot of the mounting groove 2 into adjacent first and second air outlets 22 and 23. Exemplarily, along the width direction (Y direction as shown in Figure 2 ) of the mounting groove 2, one end of the air guide structure 3 is located at one side of the mounting groove 2, and the other end of the air guide structure 3 is located at the other side of the mounting groove 2.

[0030] In addition, the air guide structure 3 is also used for mounting the first heat generating element 02 and the second heat generating element 03, and the first air outlet 22 is used for being arranged opposite to the first heat generating element 02, and the second air outlet 23 is used for being arranged opposite to the second heat generating element 03. The first heat generating element 02 and the second heat generating element 03 are exemplarily OCP cards (Open Compute Project Card).

[0031] The heat dissipation device provided by the utility model, by the first heat generating element 02 and the second heat generating element 03 are installed in the air guide structure 3, and the first heat generating element 02 is opposite to the first air outlet 22, and the second heat generating element 03 is opposite to the second air outlet 23. In the operation process of the server, the heat dissipation device can directly cool and dissipate heat for at least two heat generating elements, thereby effectively reducing the number of heat dissipation devices and the internal space of the server occupied by the heat dissipation devices, which is beneficial to reducing the heat dissipation cost of the server.

[0032] In the specific setting of the air guide structure 3, in an alternative embodiment, as shown in Figure 3 , Figure 3 The specific structure of the air guide structure 3 is used for showing, the air guide structure 3 includes an air guide part 31, a first mounting part 32 and a second mounting part 33, and reference is made to Figure 2 and Figure 3 , the air guide part 31 is arranged at the slot of the mounting groove 2, so as to separate the slot of the mounting groove 2 into adjacent first air outlet 22 and second air outlet 23. In addition, the air guide part 31 extends along the slot of the mounting groove 2 in a direction away from the groove bottom of the mounting groove 2, and the first mounting part 32 and the second mounting part 33 are located on the side of the air guide part 31 away from the slot of the mounting groove 2, and the first mounting part 32 is opposite to the first air outlet 22, and the first mounting part 32 is used for inserting the first heat generating element 02. While the second mounting part 33 is opposite to the second air outlet 23, and the second mounting part 33 is used for inserting the second heat generating element 03. In this way, according to the number and position of the heat generating element, the cold air blown by the fan 1 can be directly blown to the corresponding heat generating element through the air outlet, which is beneficial to improving the heat dissipation efficiency of the server and reducing the heat dissipation cost of the server.

[0033] It should be noted that the specific structure of the air guide part 31 can be adjusted according to actual needs, for example, the air guide part 31 can be a plate structure, as shown in Figure 2 , the extension direction of the plate structure is perpendicular to the extension surface of the end face of the slot of the mounting groove 2. Specifically, along the width direction of the slot of the mounting groove 2, one end of the plate structure is located on one side of the mounting groove 2, and the other end of the plate structure is located on the other side of the mounting groove 2. It can be understood that the air guide part 31 can also be a curved surface structure, and the cold air blown by the fan 1 can be blown to the heat generating element at the specified position along the surface of the curved surface. In addition, the number of heat generating elements can be adjusted according to actual use needs.

[0034] When specifically configuring the first mounting part 32 and the second mounting part 33, their structures can be customized according to actual needs. For example, the first mounting part 32 and the second mounting part 33 can be an integrated "I"-shaped structure. The air guide part 31 is located between the top of the integrated "I"-shaped structure and the slot of the mounting groove 2. The grooves on both sides of the integrated "I"-shaped structure are used to insert different heating elements. This simplifies the structure of the heat dissipation device while efficiently dissipating heat from multiple heating elements.

[0035] In one alternative implementation, such as Figure 4 As shown, Figure 4 This is another structural schematic diagram illustrating the heat dissipation device. The heat dissipation device also includes a third mounting part 4, which is mounted on the chassis 01 and extends along the extension direction of the end face of the mounting slot 2 (e.g., ...). Figure 4 (As shown in the X direction), the third mounting part 4 is disposed opposite to the first mounting part 32, and the third mounting part 4 is used to insert the first heating element 02. It can be understood that the first heating element 02 is inserted into both the first mounting part 32 and the third mounting part 4 in order to improve the connection stability between the first heating element 02 and the heat dissipation device.

[0036] It should be noted that the structure of the third mounting part 4 can be configured according to actual needs. For example, the shape of the third mounting part 4 can be C-shaped, and the opening of the C-shape faces the opening direction of the groove 71 of the first mounting part 32, so as to facilitate the simultaneous insertion of the first heating element 02 into the first mounting part 32 and the third mounting part 4. The third mounting part 4 and the first mounting part 32 can be configured as an integral structure or a separate structure according to actual needs.

[0037] In addition, such as Figure 4 As shown, the heat dissipation device can also be provided with a fourth mounting part 5, which is mounted on the chassis 01 and extends along the end face of the mounting slot 2 (e.g., Figure 4 (As shown in the X direction), the fourth mounting part 5 is disposed opposite to the second mounting part 33, and the fourth mounting part 5 is used to insert the second heating element 03. It can be understood that the second heating element 03 is simultaneously inserted into both the second mounting part 33 and the fourth mounting part 5 to improve the connection stability between the second heating element 03 and the heat dissipation device. It should be noted that the structure of the fourth mounting part 5 can refer to the structure of the third mounting part 4, and will not be described again here.

[0038] It is worth mentioning that, such as Figure 5 As shown, Figure 5Another use mode of the heat dissipation device is shown in the figure, the air guide structure 3 is removed, and the heat generating element is simultaneously inserted into the third mounting portion 4 and the fourth mounting portion 5, so that the heat dissipation is performed on the single heat generating element.

[0039] In one specific embodiment, as shown in the figure, Figure 2 The heat dissipation device further comprises a wind blocking portion 6, part of the wind blocking portion 6 is arranged on the end surface of the slot of the mounting groove 2 and extends along the extension direction of the end surface of the slot of the mounting groove 2. The wind blocking portion 6 is exemplarily a plate structure, part of the plate structure is parallel to the end surface of the slot of the mounting groove 2 and surrounds the slot of the mounting groove 2. The air guide structure 3 is arranged on part of the wind blocking portion 6. In this way, the flow direction of the cold air blown by the fan 1 is further limited, so that the cold air blown by the fan 1 only flows in the direction of the air guide structure 3, thereby further improving the heat dissipation efficiency of the heat dissipation device and reducing the heat dissipation cost of the server.

[0040] It should be noted that the mounting groove 2 and the wind blocking portion 6 of the heat dissipation device can be an integral structure made of plastic material, so as to improve the structural reliability and processing convenience of the heat dissipation device.

[0041] When the connection form of the air guide structure 3 and the wind blocking portion 6 is specifically arranged, in one optional embodiment, as shown in the figure, Figure 3 The air guide structure 3 further comprises an insertion portion 34, the insertion portion 34 is arranged on the side of the air guide portion 31 away from the first mounting portion 32 and the second mounting portion 33, and as shown in the figure, Figure 4 The insertion portion 34 is inserted into part of the wind blocking portion 6. Specifically, the wind blocking portion 6 is exemplarily a plate structure, and a positioning hole is arranged on the plate surface of the plate structure. The insertion portion 34 is exemplarily a protrusion protruding from the edge of the air guide portion 31, and the protrusion is used for inserting into the positioning hole.

[0042] In addition, along the direction from the groove bottom of the mounting groove 2 to the slot of the mounting groove 2, part of the side of the air guide portion 31 close to the wind blocking portion 6 abuts against the wind blocking portion 6. Specifically, when the insertion portion 34 is inserted into the positioning hole of the wind blocking portion 6, along the direction from the slot of the mounting groove 2 to the groove bottom of the mounting groove 2, the edge of the air guide portion 31 provided with the insertion portion 34 abuts against the wind blocking portion 6. The side of the first mounting portion 32 away from the air guide portion 31 is used for abutting against the case 01, and the side of the second mounting portion 33 away from the air guide portion 31 is used for abutting against the case 01. In this way, the reliable installation of the air guide structure 3 is realized, and the air guide structure 3 is simplified. In addition, the material of the air guide structure 3 can also be plastic material, so as to reduce the manufacturing cost.

[0043] It is worth mentioning that, in an optional embodiment, the air guiding structure 3 can also be provided with a clamping portion, specifically, the clamping portion is provided on the side of the air guiding portion 31 away from the first mounting portion 32 and the second mounting portion 33, and the air guiding structure 3 is clamped with the air blocking portion 6 through the clamping portion. Specifically, the clamping portion is exemplarily an elastic clamping hook protruding from the edge of the air guiding portion 31, the clamping hook is used to pass through the positioning hole of the air blocking portion 6, and the inner side wall of the head of the clamping hook is clamped with the plate surface of the air blocking portion 6 on the side close to the mounting groove 2. It can be understood that, when the air guiding structure 3 is clamped with the air blocking portion 6, the first mounting portion 32 and the second mounting portion 33 of the air guiding structure 3 can be arranged separately from the case 01.

[0044] As shown in Figure 2 , in an optional embodiment, the air blocking portion 6 includes a connecting portion 61, a first bending portion 62 and a second bending portion 63. The connecting portion 61 is arranged on the end surface of the slot of the mounting groove 2 and extends along the extension direction of the end surface of the slot of the mounting groove 2. It should be noted that the connecting portion 61 is exemplarily a plate structure, and the plate structure is parallel to the end surface of the slot of the mounting groove 2, and surrounds the slot of the mounting groove 2.

[0045] Along the extension direction (as shown in Figure 2 X direction) of the end surface of the slot of the mounting groove 2, the first bending portion 62 and the second bending portion 63 are oppositely arranged, and the connecting portion 61 is located between the first bending portion 62 and the second bending portion 63 and connected with the first bending portion 62 and the second bending portion 63. It should be noted that the first bending portion 62 is exemplarily a bending along the edge of the connecting portion 61, that is, the first bending portion 62 is perpendicular to the plate surface of the connecting portion 61 and extends in a direction away from the bottom of the slot of the mounting groove 2. In this way, the strength of the air blocking portion 6 can be improved while the flow direction of the cold air blown out by the fan 1 is further limited, thereby further improving the heat dissipation efficiency of the server. The structure of the second bending portion 63 can be referred to the first bending portion 62, which will not be described here.

[0046] In a specific embodiment, referring to Figure 1 and Figure 6 , Figure 6 , a partial structure of the heat dissipation device is shown, wherein, as shown in Figure 6 , the heat dissipation device further includes a first fixing portion 7, the first fixing portion 7 is arranged on the first bending portion 62 and is used to be clamped with the case 01. In this way, the stable connection between the heat dissipation device and the case 01 can be achieved while the disassembly convenience of the heat dissipation device is improved.

[0047] When the first fixing portion 7 is specifically arranged, as shown in Figure 7 , the first fixing portion 7 is arranged on the first bending portion 62 and extends along the extension direction of the first bending portion 62. It should be noted that the first fixing portion 7 is exemplarily a plate structure, and the plate structure is parallel to the first bending portion 62.As shown, the first fixing part 7 includes a groove 71 and a first limiting part 72. Along the direction from the bottom of the mounting groove 2 to the opening of the mounting groove 2, the opening of the groove 71 penetrates the edge of the first bent part 62. Simultaneously, the first limiting part 72 protrudes from the sidewall of the groove 71 and is spaced apart from the bottom of the groove 71. The gap between the bottom of the groove 71 and the first limiting part 72 is used to accommodate at least a portion of the chassis 01 for engaging with the chassis 01, thereby achieving a stable engagement between the first fixing part 7 and the chassis 01 while simplifying the structure of the first fixing part 7. Furthermore, the side of the first limiting part 72 near the bottom of the groove 71 is used to abut against a portion of the chassis 01 to further enhance the connection stability between the first fixing part 7 and the chassis 01.

[0048] It is worth mentioning that the first fixing part 7 can also be connected to the power supply compartment of the server.

[0049] In addition, the heat dissipation device may also include a second fixing part 8, such as Figure 2 As shown, the second fixing part 8 is disposed at the second bending part 63 and is used for detachable connection with the chassis 01, which helps to further improve the connection stability between the heat dissipation device and the chassis 01. The second fixing part 8 can be, for example, a mounting hole and a screw, with the screw passing through the mounting hole to achieve a stable connection with the chassis 01.

[0050] In a specific embodiment, such as Figure 1 As shown, the heat dissipation device also includes a fastener 9, and the mounting slot 2 is used for detachable connection with the fan 1 via the fastener 9. This allows for the replacement of different models of the fan 1 according to different heat dissipation requirements of the server, thereby improving the versatility of the heat dissipation device. The fan 1 can be, for example, a 6015 fan 1.

[0051] When specifically setting fastener 9, such as Figure 2 As shown, the fastener 9 includes a body 91, a second limiting part 92, and a third limiting part 93, along the axial direction of the body 91 (e.g., ...). Figure 2 (As shown in the Z direction), the second limiting part 92 and the third limiting part 93 are spaced apart. Along the circumference of the body 91, the second limiting part 92 and the third limiting part 93 protrude from the side wall of the body 91. It should be noted that the second limiting part 92 can be an annular shape surrounding the body 91, or it can be multiple protrusions spaced apart along the circumference of the body 91. Furthermore, the second limiting part 92 is made of a flexible material.

[0052] The bottom of the installation groove 2 is provided with an installation hole, and the size of the second limiting part 92 is greater than the hole diameter of the installation hole in the radial direction of the body 91. In this way, during the process of the body 91 and the second limiting part 92 penetrating through the installation hole in the bottom of the installation groove 2, the second limiting part 92 is deformed by the extrusion of the hole wall of the installation hole, and then the second limiting part 92 can pass through the installation hole. When the second limiting part 92 passes through the installation hole, the second limiting part 92 restores to the original state, and the side wall of the side of the second limiting part 92 close to the installation groove 2 abuts against the outer side wall of the bottom of the installation groove 2.

[0053] In addition, the body 91 is used to penetrate through the shell of the fan 1, and the shell of the fan 1 is located between the second limiting part 92 and the third limiting part 93, and the side of the third limiting part 93 close to the second limiting part 92 is used for the shell of the fan 1 to abut, so as to improve the connection convenience of the fan 1 and the installation groove 2 while realizing the stable connection of the fan 1 and the installation groove 2.

[0054] In summary, the heat dissipation device provided by the utility model, by the first heating element 02 and the second heating element 03 are installed in the air guide structure 3, and the first heating element 02 is opposite to the first air outlet 22, and the second heating element 03 is opposite to the second air outlet 23. In this way, during the operation of the server, the heat dissipation device can directly cool and dissipate heat for at least two heating elements, thereby effectively reducing the number of heat dissipation devices and the internal space of the server occupied by the heat dissipation devices, which is beneficial to reduce the heat dissipation cost of the server.

[0055] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model belong to the scope of the claims of the utility model and its equivalent technologies, the utility model also intends to include these modifications and variations.
