DETAILED DESCRIPTION

[0044] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0045] like Figure 1 As shown, a schematic diagram of the structural disassembly of a heat sink provided by an embodiment of the present invention is shown, wherein the heat sink comprises: a heat sink base 10, a heat dissipation functional component 20, and a rotating pressing pin 30; the heat dissipation functional component 20 is arranged on one side of the heat sink base, and the other side of the heat sink base is used to contact with a server board 50, a plurality of first mounting holes 11 are provided on the heat sink base 10, and a second mounting hole 51 is provided on the server board 50 corresponding to the position of each first mounting hole 11; further as shown Figure 2 As shown, a schematic diagram of the assembly of a rotary pressing nail of a heat sink provided by an embodiment of the present invention and a heat sink base is shown, wherein the rotary pressing nail 30 comprises: a nail cap 31, a nail rod 32, and a nail head 33; one end of the nail rod 32 is connected to the nail cap, and the other end of the nail rod 32 is connected to the nail head 33; an elastic member 40 is sleeved on the nail rod 32, and the nail head comprises a barb structure 331 extending along a first direction, and the rotary pressing nail 30 is used to penetrate through the corresponding first mounting hole 11 and the corresponding second mounting hole 51, so that the end of the elastic member 40 away from the nail cap 31 contacts the heat sink base 10, and the barb structure 331 is clamped with the back of the server board 50, so as to form a fixed connection between the heat sink base 10 and the server board 50; the first direction X is a direction perpendicular to the nail rod 32.

[0046] As an electronic device that runs for a long time, the server will generate a lot of heat. If it cannot be discharged immediately, it will affect the working efficiency of the server. For this reason, technicians will install a detachable radiator on the server to perform heat dissipation. As the configuration and performance of the server are improved, the demand for radiators is gradually diversified. For servers that need to run uninterruptedly for a long time, customers need radiators that can achieve tool-free quick disassembly and assembly requirements, so as to achieve rapid maintenance and replacement of modules and components inside the server or radiator, and ensure smooth operation of server services. In the related technology, screws are generally used to connect the server and the radiator, but special loading and unloading tools such as screwdrivers are required for installation and disassembly operations, which is not convenient and fast enough. In addition, during the loading and unloading process, the loading and unloading tools are easy to touch the densely arranged components in the server equipment, and the server will be damaged if not handled with care.

[0047] To this end, an embodiment of the present invention provides a radiator. In the embodiment of the present invention, the radiator includes a radiator base 10, a heat dissipation functional component 20 and a rotating pressing pin 30, an elastic member 40 is sleeved on the rotating pressing pin, a first mounting hole 11 is opened on the radiator base 10, and a second mounting hole 51 is opened on the server board 50 at a position corresponding to the first mounting hole.

[0048] During the installation of the radiator, the rotary pressing nail 30 can be directly manually pressed into the first mounting hole 11 of the radiator base 10 to complete the installation of the rotary pressing nail 30 on the radiator; on this basis, the rotary pressing nail 30 can be manually pressed down and rotated to adjust the positional relationship between the hook structure 331 of the rotary pressing nail 30 and the second mounting hole 51 of the server board 50, so that the rotary pressing nail 30 can pass through the second mounting hole 51, and at the same time, the end of the elastic member 40 away from the nail cap 31 abuts against the first mounting hole 11, so that the elastic member 40 is compressed and elastic potential energy is generated. When the rotary pressing nail 30 is pressed down to the first mounting hole 11 of the radiator base 10 and the second mounting hole 51 of the server board 50 at the same time, the rotary pressing nail 30 is rotated again. At this time, the second mounting hole 51 will be stuck with the hook structure 331. The structure 331 is formed by the screw threading device 32, and the screw threading device 33 is pressed against the screw threading device 32 to prevent the rotary pressing nail 30 from withdrawing through the second mounting hole 51. Then, the rotary pressing nail 30 is released, the elastic member 40 is reset, and the elastic potential energy is released, so that the rotary pressing nail 30 is pushed back along the direction from the nail head 33 to the nail cap 31. Through the obstruction of the second mounting hole 51 and the release of the elastic potential energy of the elastic member 40, the barb structure 331 is firmly clamped on the second mounting hole 51, that is, clamped on the back of the server board 50. At this point, the fixed connection between the radiator base 10 and the server board 50 is completed, and the installation of the radiator on the server is also completed. The rotary pressing nail 30 can be installed on the radiator base 10 by manually pressing down. The radiator base 10 and the server board 50 can be fixedly connected by manually pressing down and rotating the rotary pressing nail 30. No additional installation tools are required, which is quick and convenient.

[0049] During the disassembly process of the radiator, the rotating pressing pin 30 can be manually pressed down to compress the elastic member 40 and generate elastic potential energy, and then the rotating pressing pin 30 can be manually rotated to adjust the positional relationship between the hook structure 331 of the rotating pressing pin 30 and the second mounting hole 51 of the server board 50, so that the rotating pressing pin 30 can pass through the second mounting hole 51. Finally, the rotating pressing pin 30 is released, the elastic member 40 is reset, and the elastic potential energy is released to push the rotating pressing pin 30 back along the direction from the nail head 33 to the nail cap 31. When the rotating pressing pin 30 is pushed out of the second mounting hole 51 by the elastic member 40, the separation of the radiator base 10 and the server board 50 is completed, and the disassembly of the radiator on the server is also completed. The entire disassembly process only requires manually pressing down and rotating the rotating pressing pin 30.

[0050] In the present invention, an elastic member is provided for the rotary pressing pin, and corresponding first mounting holes and second mounting holes are opened on the heat sink base and the server board; during the installation process, the rotary pressing pin is manually rotated to adjust the positional relationship between the hook structure and the second mounting hole, so that the rotary pressing pin passes through the heat sink base and the server board at the same time, and the hook structure is firmly clamped on the back of the server board through the cooperation of the hook structure of the rotary pressing pin and the elastic member, thereby completing the fixed connection between the heat sink base and the server board; during the disassembly process, the rotary pressing pin is pressed down and rotated, and the elastic member automatically pushes the rotary pressing pin out of the second mounting hole, thereby completing the separation of the heat sink base and the server board; the entire installation and disassembly process only requires manual rotation and pressing of the rotary pressing pin, without the need for additional disassembly tools, which is quick and convenient, the process is fast, the assembly is firm, and the disassembly is simple, which solves the problem of requiring the use of special disassembly tools for loading and unloading the heat sink in the related technology, and meets the demand for tool-free quick disassembly and assembly of the heat sink.

[0051] Optional, such as Figure 2 As shown, the nail head 33 is a deformable nail head, and the extension length of the barb structure 331 along the first direction X is greater than the aperture of the first mounting hole 11. Further, as shown in FIG. Figure 3 As shown, a schematic diagram of the assembly of a rotating pressing pin of a radiator provided by an embodiment of the present invention and a radiator base is shown, wherein the deformable pin head is used to deform to an extended length less than the aperture of the first mounting hole 11, pass through the first mounting hole 11, and after passing through the first mounting hole 11, restore to an extended length greater than the aperture of the first mounting hole 11.

[0052] The nail head of the rotary pressing nail is a deformable nail head, and the barb mechanism of the deformable nail head extends along the first direction, and the extended length is greater than the aperture of the first mounting hole. Through such an arrangement, the deformable nail head can pass through the first mounting hole by deformation, and after passing through the first mounting hole, the deformable nail head is restored. At this time, the extended length of the barb structure is greater than the aperture of the first mounting hole 11, so that the first mounting hole prevents the deformable nail head from retreating and withdrawing from the first mounting hole. In this way, the preliminary installation of the rotary pressing nail on the radiator base can be completed; for the material of the deformable nail head, elastic materials such as silicone or rubber can be selected, and the embodiments of the present invention do not make specific restrictions on this.

[0053] Optional, such as Figure 4 As shown, a schematic diagram of the structure of a rotating pressing pin of a heat sink provided by an embodiment of the present invention is shown, wherein the deformable pin head further includes a through hole 332 and a chamfered structure 333; the through hole 332 is symmetrically arranged at the center of the deformable pin head, and the chamfered structure 333 is arranged at the top of the deformable pin head.

[0054] Symmetrical through holes are arranged in the deformable nail head, and a chamfered structure is arranged at the top of the deformable nail head, so that when the chamfered structure of the deformable nail head abuts against the first mounting hole, the extended part of the barb structure on the deformable nail head is moved along the Figure 2 The middle Y direction is gathered toward the center of the nail rod, and the symmetrically arranged through holes provide deformation space for the barb mechanism, so that the deformable nail head will not deform perpendicularly to the first direction to prevent the deformable nail head from passing through the first mounting hole.

[0055] Optionally, the circumscribed shape of the second mounting hole 51 is a rectangle; Figure 2 As shown, the barb structures 331 are symmetrically arranged on both sides of the axis of the nail rod 32. Figure 5 As shown, a schematic diagram of a positional relationship between a barb structure of a rotating pressing pin of a heat sink and a second mounting hole, the extension length of the barb structure 331 along the first direction X is greater than the wide side of the rectangle, such as Figure 6 , which shows another schematic diagram of the positional relationship between the barb structure of the rotary pressing pin of a heat sink and the second mounting hole, wherein the extension length of the barb structure 331 along the first direction X is smaller than the long side of the rectangle;

[0056] like Figure 6 As shown, the second mounting hole 51 is used to allow the nail head 33 to pass through when the extension direction of the barb structure 331 is parallel to the long side of the rectangle; Figure 5 As shown, the second mounting hole is used to prevent the nail head 33 from passing through when the extension direction of the barb structure 331 is not parallel to the long side of the rectangle;

[0057] like Figure 7As shown, a top view of a radiator base of a radiator provided by an embodiment of the present invention is shown, an unlocking identification structure 12 and a locking identification structure 13 are arranged outside a first mounting hole 11; a line connecting the unlocking identification structure 12 and the center of the first mounting hole 11 is perpendicular to a line connecting the locking identification structure 13 and the center of the first mounting hole 11;

[0058] like Figure 2 As shown, the nail cap is provided with a direction indicating structure 311, and the direction indicating structure 311 changes the indicating direction as the rotating pressing nail 30 rotates. When the direction indicating structure 311 points to the unlocking identification structure 12, as shown in FIG. Figure 6 As shown, the extension direction of the barb structure 331 is parallel to the long side of the rectangle; when the direction indicating structure 311 points to the locking identification structure 13, as shown in FIG. Figure 5 As shown, the extending direction of the barb structure 331 is perpendicular to the long side of the rectangle.

[0059] The second mounting hole can be set to an ellipse or a rectangle. For ease of understanding, in the embodiment of the present invention, the relationship between the sides of the second mounting hole is expressed by the external figure of the second mounting hole; the external figure of the second mounting hole is a rectangle with vertical long sides and wide sides; the hook mechanism of the rotary pressing nail is symmetrically arranged on both sides of the nail rod 32, so that from the perspective of the nail head to the nail cap, the nail head is also in the shape of a rectangular external figure. In order to avoid misunderstanding, unless otherwise specified, the rectangle mentioned in the embodiment of the present invention refers to the external figure of the second mounting hole 51; the long side of the rectangle is greater than the extension length of the hook structure along the first direction, and the short side of the rectangle is less than the extension length of the hook structure along the first square. In this way, when the long side of the rectangle is parallel to the extension direction of the hook mechanism, the nail head can pass through the second mounting hole without being blocked. In other cases, because the extension length of the hook mechanism is greater than the wide side of the rectangle, the second mounting hole will block the hook mechanism, thereby preventing the nail head from passing through the second mounting hole.

[0060] After the rotary pressing pin is pressed into the first mounting hole and the first mounting hole is aligned with the second mounting hole, the radiator base will cover the second mounting hole on the server board and the barb structure of the rotary pressing pin. In order to facilitate observation of whether the extension direction of the barb structure is parallel to the long side of the rectangle, an unlocking identification structure and a locking identification structure are set at a convenient observation position outside the first mounting hole of the radiator base, and the two are respectively perpendicular to the line connecting the centers of the first mounting holes; at the same time, a direction indicating structure is set on the nail cap of the rotary pressing pin; through the direction indicating structure pointing to the unlocking identification structure or the locking identification structure, the user can clearly understand the positional relationship between the covered rectangle and the covered barb structure. Specifically, when the direction indicating structure points to the unlocking identification structure, the extension direction of the barb structure is parallel to the long side of the rectangle, and when the direction indicating structure points to the locking identification structure, the extension direction of the barb structure is perpendicular to the long side of the rectangle.

[0061] Optional, such as Figure 4 As shown, the direction indicating structure 311 is parallel to the first direction X;

[0062] When the first mounting hole 11 is aligned with the second mounting hole 51 , the unlocking identification structure 12 corresponds to the wide side of the rectangle, and the locking identification structure 13 corresponds to the long side of the rectangle.

[0063] As for the specific setting orientations of the direction indicating structure, the unlocking identification structure, and the locking identification structure, in a preferred scheme of an embodiment of the present invention, the direction indicating structure is set to be parallel to the first direction, that is, the extension direction of the barb structure, and correspondingly, the unlocking identification structure and the locking identification structure are set as follows: when the first mounting hole is aligned with the second mounting hole, the unlocking identification structure is placed on the side of the wide side of the rectangle corresponding to the first mounting hole, and the locking identification structure is placed on the side of the long side of the rectangle corresponding to the first mounting hole; preferably, the first mounting hole is an arc square hole, that is, a figure composed of parallel straight edges and relative arc edges. When the first mounting hole is an arc square hole, its straight edges correspond to the long sides of the rectangle, and its arc edges correspond to the wide sides of the rectangle. At this time, the unlocking identification structure is placed on the outside of the arc edges, and the locking identification structure is placed on the outside of the straight edges; through the above setting method, when the direction indicating structure points to the unlocking identification structure, the extension direction of the barb structure is parallel to the long sides of the rectangle, and when the direction indicating structure points to the locking identification structure, the extension direction of the barb structure is perpendicular to the long sides of the rectangle.

[0064] In an embodiment not shown in the present invention, the direction indicating structure can also be set to point perpendicularly to the first direction, that is, parallel to the direction of the perpendicular bisector of the barb structure. Correspondingly, the unlocking identification structure and the locking identification structure are arranged as follows: when the first mounting hole is aligned with the second mounting hole, the unlocking identification structure is placed on the side of the long side of the rectangle corresponding to the first mounting hole, and the locking identification structure is placed on the side of the short side of the rectangle corresponding to the first mounting hole; through the above arrangement, it can also be achieved that when the direction indicating structure points to the unlocking identification structure, the extension direction of the barb structure is parallel to the long side of the rectangle, and when the direction indicating structure points to the locking identification structure, the extension direction of the barb structure is perpendicular to the long side of the rectangle.

[0065] Optional, such as Figure 4 The nail rod includes: a first rod body 321 and a second rod body 322, one end of the first rod body is connected to the nail cap 31, the other end of the first rod body 321 is connected to one end of the second rod body 322, and the other end of the second rod body 322 is connected to the nail head 33; the diameter of the first rod body 321 is greater than the diameter of the second rod body 322, so that the connection position of the first rod body and the second rod body constitutes a cylindrical step structure, and the diameter of the first rod body is greater than the aperture of the first mounting hole.

[0066] The nail rod is set to a first rod body and a second rod body with different diameters, and the diameter of the first rod body near the nail cap is larger, which is not only larger than the diameter of the second rod body, but also larger than the aperture of the first mounting hole. According to this arrangement, in the process of pressing down the rotating pressing nail, only the second rod body and the nail head pass through the first mounting hole and the second mounting hole. The limit state of pressing down the rotating pressing nail is that the cylindrical step structure formed by the connection position of the first rod body and the second rod body abuts against the first mounting hole. Through the above arrangement, the pressing distance of the rotating pressing nail is limited during the installation or removal of the radiator, avoiding the problem of excessive deformation and failure of the elastic part caused by excessive pressure by the user. In addition, when the cylindrical step structure abuts against the first mounting hole, it will limit the nail rod of the rotating pressing nail to be perpendicular to the plane where the radiator base is located, so that the rotating pressing nail can vertically pass through the radiator base and the server board, which is convenient for the subsequent rotation adjustment of the rotating pressing nail.

[0067] Optionally, the length of the elastic member 40 in the unextended state is greater than the axial length of the first rod body 321, and one end of the elastic member 321 abuts against the nail cap 31; the diameter of the elastic member 40 is smaller than the diameter of the nail cap 31, and the diameter of the elastic member 31 is greater than the diameter of the first mounting hole 11.

[0068] The diameter of the elastic member is smaller than the diameter of the nail cap but larger than the aperture of the first mounting hole, so that when the elastic member is sleeved on the nail rod, one end thereof abuts against the nail cap, and the other end abuts against the first mounting hole during the process of pressing down and rotating to press the nail; the length of the elastic member is greater than the axial length of the first rod body, so that when the cylindrical step formed by the connection position of the first rod body and the second rod body abuts against the first mounting hole, the elastic member undergoes elastic deformation to store elastic potential energy.

[0069] Optional, such as Figure 4 As shown, a fixing post 3311 is provided on one side of the barb structure 331 facing the nail cap. Figure 8 As shown, a top view of a server board connected to a radiator provided in an embodiment of the present invention is shown, a fixing hole 52 corresponding to the fixing pile is opened on the outer side of the long side of the rectangle corresponding to the second mounting hole 51, and the fixing pile 3311 is inserted into the fixing hole 52 when the barb structure 331 is clamped on the back of the server board 50 and the extension direction of the barb structure 331 is perpendicular to the long side of the rectangle.

[0070] A fixing pile is provided on the hook structure, and a fixing hole corresponding to the fixing pile is opened on the outside of the second mounting hole of the server board. The fixing hole is arranged on the outside of the long side of the rectangle, and its specific position is related to the clamping position of the hook structure on the back of the server board. In the preferred scheme of the embodiment of the present invention, the fixing hole is arranged at the center of the outside of the long side of the rectangle, and the extension direction of the corresponding hook mechanism is perpendicular to the long side of the rectangle; after the rotating pressing pin passes through the second mounting hole, when the direction indicating structure points to the locking identification structure and the rotating pressing pin is released, the hook mechanism is clamped at the center of the long side length of the rectangle, and the fixing pile is inserted into the fixing hole. The fixing pile is constrained by the wall of the fixing hole, so that the rotating pressing pin cannot continue to rotate, and the hook structure is locked on the back of the server board, further realizing the fixed connection between the radiator base and the server board.

[0071] Optional, such as Figure 7 As shown, the radiator base 10 is a quadrilateral, and the first mounting holes 11 are arranged at positions on the quadrilateral including: at the four corners of the quadrilateral or at a group of diagonal corners of the quadrilateral.

[0072] The radiator base is set as a quadrilateral, and first mounting holes are opened at the four corners of the quadrilateral or a group of diagonal corners, so that the first mounting holes and the corresponding second mounting holes are easier to align, and the radiator base can fully contact the server board to conduct the heat generated by the operation of the server.

[0073] In the embodiment of the present invention, by rotating the rotary pressing pin, the direction indicating structure of the rotary pressing pin points to the unlocking identification structure or the locking identification structure, and the positional relationship between the hook structure of the rotary pressing pin and the rectangle circumscribed to the second mounting hole is adjusted, so that when the direction indicating structure points to the unlocking identification structure, the nail head can pass through the second mounting hole, and when the direction indicating structure points to the locking identification structure, the nail head cannot pass through the second mounting hole and the hook structure is locked on the back of the server board; by pressing down the rotary pressing pin, the two ends of the elastic member sleeved on the rotary pressing pin are respectively squeezed by the nail cap and the first mounting hole, elastic deformation occurs, and elastic potential energy is generated and stored; after releasing the rotary pressing pin, the elastic member between the nail cap and the first mounting hole is reset, the elastic potential energy is released, and the nail cap is pushed outward, thereby driving the rotary pressing pin Retract in the direction from the second mounting hole to the first mounting hole. If the direction indicating structure points to the unlocking identification structure at this time, the elastic member will push the rotary pressing pin out of the second mounting hole to complete the separation of the radiator base and the server board. If the direction indicating structure does not point to the unlocking identification structure at this time, the elastic member will push the hook structure of the rotary pressing pin to press the back of the server board to complete the fixed connection between the radiator base and the server board. If the direction indicating structure points to the locking identification structure, the elastic member will insert the fixing pile into the fixing hole while pressing the hook structure to press the back of the server board to complete the locking of the rotary pressing pin and strengthen the fixed connection between the radiator base and the server board. Through the above means, the radiator base can be disassembled and assembled on the server board without the assistance of tools, only manual operation is required.

[0074] Second, as Figure 1 As shown, an embodiment of the present invention provides a server, the server includes a server board 50, a device to be cooled 60 and a radiator; the radiator includes: a radiator base 10, a cooling functional component 20, and a rotating pressing pin 30;

[0075] The heat dissipation device 60 is arranged between the server board 60 and the heat sink base 10, the heat dissipation functional component 20 is arranged on one side of the heat sink base 10, and the other side of the heat sink base 10 is used to contact the server board 50; a plurality of first mounting holes 11 are provided on the heat sink base, and a second mounting hole 51 is provided on the server board 60 corresponding to the position of each first mounting hole 11;

[0076] like Figure 2As shown, the rotary pressing nail 30 includes: a nail cap 31, a nail rod 32, and a nail head 33; one end of the nail rod 32 is connected to the nail cap 31, and the other end of the nail rod 32 is connected to the nail head 33; an elastic member 40 is sleeved on the nail rod 32, and the nail head 33 includes a barb structure 331 extending along the first direction X. The rotary pressing nail 30 is used to penetrate through the corresponding first mounting hole 11 and the corresponding second mounting hole 51, so that the end of the elastic member 40 away from the nail cap 31 contacts the radiator base 10, and the barb structure 331 is clamped with the back of the server board 50, forming a fixed connection between the radiator base 10 and the server board 50.

[0077] The device to be cooled 60 may be a device that is mainly responsible for logic operations in the entire server or other components that generate relatively high heat during operation.

[0078] For the specific implementation methods of each device in the radiator and the effect of the positional relationship between each device in the radiator and the server board, please refer to the radiator-related content provided in the first aspect of the specific implementation method of this specification, which will not be repeated here.

[0079] Thirdly, Fig.12 As shown, a flowchart of a method for mounting and disassembling a radiator provided by an embodiment of the present invention is shown. An embodiment of the present invention provides a method for mounting and disassembling a radiator, which is applied to the server described above. The method for mounting and disassembling a radiator includes:

[0080] Step 101: Press the rotary pressing pin into the first mounting hole, and the direction indicating structure of the rotary pressing pin points to the unlocking identification structure, thereby completing the installation of the rotary pressing pin on the heat sink base;

[0081] In step 101, the chamfered structure of the rotary pressing nail is aligned with the first mounting hole, and the rotary pressing nail is pressed down, so that the deformable nail head of the rotary pressing nail will be deformed, that is, the barb structure of the rotary pressing nail is deformed as shown in FIG. Figure 2 The center of the nail rod of the Y-direction rotating pressing nail is folded, and after the deformable nail head is deformed to the point where the extension length of the barb structure along the first direction is smaller than the aperture of the first mounting hole, as shown in FIG. Figure 3 As shown, the rotary pressing pin will be pressed into the first mounting hole, and the deformable pin head will return to its initial state after passing through the first mounting hole. At the same time, the rotary pressing pin can be rotated so that the direction indicating structure of the rotary pressing pin points to the unlocking identification structure, thereby completing the installation of the rotary pressing pin on the radiator base.

[0082] Step 102: aligning the first mounting hole and the corresponding second mounting hole, pressing down the rotating pressing pin so that the barb structure of the rotating pressing pin passes through the second mounting hole, rotating the rotating pressing pin so that the direction indicating structure points to the locking identification structure, and releasing the rotating pressing pin to complete the installation of the heat sink on the server;

[0083] Based on step 101, step 102 may be performed. Step 102 may be divided into the following four sub-steps in chronological order:

[0084] Sub-step 1021, moving the heat sink base, aligning the first mounting hole with the corresponding second mounting hole, and determining a connection position for the rotating pressing pin;

[0085] Sub-step 1022: Fig. 9 FIG. 1 is a schematic diagram of an assembly of a heat sink provided by an embodiment of the present invention in an installation state, wherein Fig. 9 a in the figure represents the top view in this state. Fig. 9 b in the figure represents the side cross-sectional view in this state. Fig. 9 c in the figure represents the top view in this state; the rotary pressing nail is pressed down, because the direction indicating structure 311 of the rotary pressing nail is set to point to the unlocking identification structure 12 in step 101, so at this time, the extension direction X of the barb structure 331 of the rotary pressing nail is parallel to the long side of the rectangle circumscribed on the second mounting hole, so that the barb structure 331 can pass through the second mounting hole 51; while pressing down the rotary pressing nail, the elastic member 40 sleeved on the nail rod will be compressed and deformed along the nail rod because its two ends are squeezed by the nail cap 31 and the outer side of the first mounting hole 11, thereby generating elastic potential energy accumulated on the elastic member, and the limit of pressing down is to make the first column abut against the first mounting hole;

[0086] Sub-step 1023: Fig.10 FIG. 1 is a schematic diagram of another installation state of a radiator provided by an embodiment of the present invention, wherein Fig.10 The d in the figure represents the top view in this state. Fig.10 The e in the figure represents the oblique downward view in this state. Fig.10 f in the figure represents the bottom view in this state; Fig. 9 The rotating pressing nail is rotated in the Z direction shown in c in the figure, so that the direction indicating structure 311 points to the locking identification structure 13. At this time, the extension direction X of the barb structure 311 is perpendicular to the long side of the rectangle circumscribed with the second mounting hole 51, and the second mounting hole 51 blocks the barb structure from passing through. At the same time, the fixing pile 3311 on the barb structure is aligned with the fixing hole 52 on the server board;

[0087] Sub-step 1024: Fig.11 FIG. 1 is a schematic diagram of another installation state of a radiator provided by an embodiment of the present invention, wherein Fig.11 The g in the figure represents the top view in this state. Fig.11 h in the figure represents the side cross-sectional view in this state. Fig.11The i in the figure represents the top view in this state; release the rotary pressing nail, and the elastic member 40 sleeved on the nail rod will reset after the external force is removed. Since the two ends of the elastic member 40 have respectively abutted against the outer side of the first mounting hole 11 and the nail cap 31, the elastic potential energy accumulated on the elastic member is released, so that the elastic member recovers along the direction of the nail rod, and at the same time pushes the nail cap 31 away from the outer side of the first mounting hole 11. At this time, the entire rotary pressing nail will be pushed by the elastic member 40 in the direction opposite to the downward pressure. Under the premise that the hook structure 331 cannot pass through the second mounting hole 51, the hook structure 331 will press the back of the server board to form a firm clamping connection. At the same time, the fixing column 3311 on the hook structure will be inserted into the fixing hole 52 of the server board to complete the locking of the rotary pressing nail. At this point, the entire process of installing the radiator on the server is completed.

[0088] Step 103: When disassembling the heat sink, press down and rotate the rotary pressing pin so that the direction indicating structure points to the unlocking identification structure; release the rotary pressing pin and withdraw the rotary pressing pin from the second mounting hole to complete the disassembly of the heat sink on the server;

[0089] When the radiator needs to be removed from the server, step 103 may be performed. Step 103 may be divided into the following sub-steps according to the time sequence:

[0090] Sub-step 1031, pressing down the rotary pressing nail; the fixing pile on the barb structure is separated from the fixing hole on the server board, so that the rotary pressing nail can rotate. When the rotary pressing nail is pressed down, the elastic member sleeved on the nail rod will be compressed and deformed along the nail rod because its two ends are squeezed by the nail cap and the outer side of the first mounting hole, thereby generating elastic potential energy accumulated on the elastic member. The limit of pressing down is to make the first column abut against the first mounting hole.

[0091] Sub-step 1032, rotating the rotary pressing pin so that the direction indicating structure points to the unlocking identification structure; at this time, the extension of the barb structure along the first direction is parallel to the long side of the rectangle circumscribed with the second mounting hole, and the second mounting hole allows the barb structure to pass through;

[0092] Sub-step 1033, release the rotary pressing nail; the elastic member sleeved on the nail rod will reset after the external force is removed. Since the two ends of the elastic member have respectively abutted against the outside of the first mounting hole and the nail cap, the elastic potential energy accumulated on the elastic member is released, so that the elastic member recovers along the direction of the nail rod and pushes the nail cap away from the outside of the first mounting hole. At this time, the entire rotary pressing nail will be pushed by the elastic member in the direction opposite to the downward pressure. On the premise that the barb structure can pass through the second mounting hole, the rotary pressing nail will be pushed out of the second mounting hole by the elastic member; the rotary pressing nail exits the second mounting hole, completing the separation of the server board and the radiator base, and the radiator is removed from the server.

[0093] In the radiator mounting and disassembly method, the server and radiator described in the embodiment of the present invention are installed and disassembled by rotating the pressing pin, the first mounting hole, the second mounting hole and the elastic member, and each step can be completed manually without the assistance of mounting and disassembly tools. The steps are simple, saving operation time and occupying less operating space, thus meeting the needs of tool-free quick disassembly and assembly of the radiator.
