Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of computing devices, and in particular to a heat sink and a disassembly and assembly tool for the heat sink. Background Art

[0002] There are a large number of power devices such as chips and memory sticks in computing devices such as servers. These power devices will emit a large amount of heat during use. Therefore, a heat sink needs to be installed inside the computing device.

[0003] In the related art, the radiator is generally assembled by screws, and in order to ensure the reliability of the connection, the number of screws will be large, and each screw is provided with a slot such as a slot or a cross slot. During the specific installation, the on-site staff can use a screwdriver to insert a slot such as a slot or a cross slot to tighten each screw separately, thereby realizing the assembly of the radiator. However, due to factors such as operating errors, the tightening degree of each screw is often not guaranteed to be consistent, which makes the radiator prone to warping and high pressure on one side during use. This will not only affect the installation reliability of the radiator, but also affect the service life of the radiator.

[0004] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] An embodiment of the present application provides a heat sink and a disassembly and assembly tool for the heat sink, wherein the disassembly and assembly tool can realize the synchronous driving rotation of each threaded connector, which can greatly improve the disassembly and assembly efficiency of the heat sink, and is beneficial to ensuring the consistency of the tightening degree of each threaded connector, as well as the reliable installation and service life of the heat sink, and can also reduce the possibility of damage to the components to be cooled.

[0006] In the first aspect, an embodiment of the present application provides a disassembly and assembly tool for a radiator, the radiator comprising a main body and a plurality of threaded connectors arranged on the main body, each of the threaded connectors being provided with a transmission tooth portion; the disassembly and assembly tool comprises: a ring chain, the ring chain being configured to be able to be externally mounted on the radiator and to be able to mesh with each transmission tooth portion; and a power application portion, the power application portion being configured to be able to drive the ring chain to rotate.

[0007] When installing the radiator, the ring chain can rotate under the action of the force applying part, and can drive each threaded connector to rotate synchronously, so that the synchronous tightening of each threaded connector can be achieved, and the consistency of the tightening degree of each threaded connector can be better guaranteed, so that the force of the body at each threaded connector can be relatively uniform, which is conducive to ensuring the reliable connection and service life of the radiator. In addition, since the threaded connectors of the radiator are tightened synchronously, compared with the separate tightening of each threaded connector in the related art, the disassembly and assembly tool provided in the embodiment of the present application can also improve the installation efficiency of the radiator and can greatly save installation time.

[0008] The above disassembly tool can also be used for disassembly of the radiator. When disassembling the radiator, the circular chain drives the threaded connectors to rotate synchronously under the action of the power application part. Therefore, the disassembly efficiency of the radiator can also be improved; in this way, when the radiator is found to be damaged and needs to be replaced, the efficiency of disassembly, assembly and replacement of the entire radiator can be improved.

[0009] The above-mentioned radiator can specifically be a radiator used in a server for dissipating heat for a central processing unit (CPU) and the like. Reliable connection of the radiator can be achieved based on the above-mentioned disassembly and assembly tooling, so the heat dissipation effect of the radiator on the CPU can be guaranteed. The pressure of the radiator on various positions of the CPU is also relatively balanced, which can reduce damage to the CPU, such as damage to the CPU socket pins caused by bent pins, and is also conducive to ensuring the normal operation of the server.

[0010] In some optional implementations, at least one threaded connector is provided with a rotation drive slot, and the power applying portion includes a force applying rod, which is configured to be partially inserted into the rotation drive slot to drive the threaded connector provided with the rotation drive slot to rotate.

[0011] In this implementation method, the power applying part first cooperates with a threaded connection part provided with a rotation drive groove to drive the threaded connection part to rotate, and then indirectly drives the ring chain to rotate, and then the ring chain drives the transmission teeth of the remaining threaded connections to rotate. At this time, the structural form of the power applying part can be relatively simple.

[0012] Only some of the threaded connectors may be provided with a rotation drive groove, for example, only one threaded connector may be provided with a rotation drive groove, while the other threaded connectors may not be provided with a rotation drive groove. In this way, the structure of some threaded connectors can be simplified, and the structure of the entire radiator can be simplified. Of course, all of the threaded connectors may also be provided with a rotation drive groove; in this way, even if the rotation drive groove of one threaded connector is damaged, the force rod can still drive the other threaded connectors to drive the ring chain to rotate, and it will not affect the normal disassembly and assembly of the radiator.

[0013] The rotation driving groove can specifically be a groove body with a non-circular cross section, such as a slot, a cross slot, a hexagonal slot, etc., and the structural form of the force applying end only needs to match the rotation driving groove.

[0014] In some optional implementations, the power application unit further includes a driving element, which is connected to the force application rod and is used to drive the force application rod to rotate. The driving element can be, for example, a motor, a pneumatic element, a hydraulic element, etc., which can improve the automation of the equipment and reduce the labor intensity of the staff.

[0015] In some optional implementations, the power applying portion includes a driving tooth portion, the driving tooth portion is meshed with the endless chain, and the driving tooth portion is configured to drive the endless chain to rotate.

[0016] In this implementation, each threaded connector of the radiator does not need to be configured with a structure that matches the power application part, and the structural form of the threaded connector and the radiator can be relatively simple. In addition, there is no need to consider the problem of thread slippage caused by the direct action of the power application part and the threaded connector in the related art. In other words, in this implementation, the power application part and the ring chain are matched with teeth and grooves, the transmission reliability is higher, the driving teeth and the ring chain are not easy to be damaged, and it is more conducive to ensuring the smooth driving of each threaded connector.

[0017] In some optional implementations, a frame is further included, the power applying part is installed on the frame, and the frame is configured with a plurality of positioning parts, and the positioning parts are used to locate the relative positions of the body and the frame.

[0018] The frame can be used to perform integrated assembly of the disassembly tool provided in the embodiment of the present application, thereby improving the integration of the disassembly tool provided in the embodiment of the present application, and facilitating the overall displacement and transportation of the disassembly tool, etc. The positioning portion is used to locate the relative position of the body and the frame, thereby improving the stability of the disassembly tool provided in the embodiment of the present application when disassembling or installing the radiator.

[0019] In some optional implementations, the positioning portion includes a positioning rod and a pressure head configured on the positioning rod, the positioning rod is used to contact the outer peripheral wall of the body, and the pressure head is used to contact the body along the axial direction of the positioning rod. The pressure head and the positioning rod can position the body from two different directions, which is more conducive to improving the reliability of positioning.

[0020] The pressure head and the positioning rod can be an integrally formed one-piece structure; or, the pressure head and the positioning rod can be processed separately and then assembled. The pressure head can be an annular protrusion, in which case, the pressure head can be arranged around the positioning rod; or, the pressure head can be distributed at a local position on the circumference of the positioning rod, for example, the pressure head can be distributed only on one side of the outer peripheral wall of the positioning rod facing the radiator, so as to facilitate the pressure head to press the radiator, and at the same time, it can also reduce the volume of the pressure head and reduce the weight of the positioning part.

[0021] In some optional implementations, at least one control switch is provided on the frame, the control switch is communicatively connected with the power application unit, and the control switch is used to control the start and stop of the power application unit.

[0022] The number of control switches may be two, corresponding to the installation and removal of the radiator respectively. For example, one of the control switches may be an installation start switch, and the other control switch may be a removal start switch. When the installation start switch is pressed, the driving element may drive each threaded connector to rotate in a direction of gradually increasing screw-in depth through an annular chain, thereby achieving installation and fixation of the radiator; when the removal start switch is pressed, the driving element may drive each threaded connector to rotate in a direction of gradually decreasing screw-in depth through an annular chain, thereby achieving removal of the radiator.

[0023] The control switch may not be arranged on the frame, for example, it may be directly arranged on the power applying part or at other positions, as long as it can realize the control of the power applying part.

[0024] In a second aspect, an embodiment of the present application also provides a heat sink, comprising a main body and a plurality of threaded connectors arranged on the main body, each threaded connector being provided with a transmission tooth portion, each transmission tooth portion being configured to be able to engage with an annular chain, and each transmission tooth portion being further configured to be able to rotate synchronously driven by the annular chain, so as to be threadably assembled on a main board or removed from the main board.

[0025] The above-mentioned heat sink is configured with transmission teeth on the threaded connectors, so that each threaded connector can rotate synchronously under the drive of the ring chain, so that each threaded connector can be tightened or loosened synchronously, which can greatly improve the efficiency of installation and disassembly, and can ensure the consistency of the tightening degree of each threaded connector, so that the force of the body at each threaded connector can be relatively uniform, which is conducive to ensuring the reliable connection and service life of the heat sink. In addition, when the threaded connectors are tightened synchronously, the locking force applied by each threaded connector is basically consistent, so that the pressure of the heat sink on each position of the components to be cooled (such as the CPU) on the motherboard is relatively balanced, and the damage to the components to be cooled can be reduced, which is more conducive to ensuring the normal operation of the motherboard and the computing device equipped with the motherboard.

[0026] In some optional implementations, the transmission tooth portion is the head of the threaded connector, and the transmission tooth portion of at least one threaded connector is provided with a rotation drive groove. In this way, the transmission tooth portion can be processed using the existing structure of the threaded connector, and the structural form of the threaded connector can be relatively simple, and accordingly, the structural form of the entire radiator can also be relatively simple; by providing a rotation drive groove for the transmission tooth portion of the threaded connector, it is convenient to directly apply a driving force to the threaded connector through the rotation drive groove, and then the threaded connector drives the annular chain to rotate, so as to simplify the structure of the disassembly and assembly tooling of the aforementioned radiator.

[0027] As mentioned above, the threaded connector may not be provided with a rotation drive groove. In this case, the power application part of the disassembly and assembly tooling can directly drive the ring chain by providing a driving tooth part, and then the ring chain can indirectly drive the threaded connectors to rotate. This is also feasible.

[0028] In some optional implementations, the main body is provided with a mounting hole, the threaded connecting member includes a rod portion, the rod portion is provided with a threaded hole, the rod portion is provided with a transmission tooth portion and a baffle portion, the baffle portion and the transmission tooth portion are arranged at intervals along the axial direction of the rod portion, and the transmission tooth portion and the baffle portion are respectively located on both axial sides of the mounting hole; it also includes a gasket and an elastic member, the gasket is located between the baffle portion and the main body, and the elastic member is located between the transmission tooth portion and the main body.

[0029] In the above implementation, the cooperation of the elastic member and the gasket can improve the installation stability of the threaded connector on the main body, and can largely avoid the threaded connector from tipping over and falling over, so that the threaded connector can stably cooperate with the ring chain.

[0043] Please refer to Figure 1-Figure 5 , Figure 1 This is a schematic diagram of the disassembly and assembly tooling of the radiator and the connection structure of the radiator provided in the embodiment of the present application. Figure 2 This is a simplified structural diagram of the radiator provided in the embodiment of the present application. Figure 3 for Figure 2 The connection structure diagram of the radiator, the ring chain and the driving gear. Figure 4 for Figure 2 The connection structure diagram of the radiator and the ring chain. Figure 5 It is a cross-sectional view of the connection between the threaded connector and the body.

[0044] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a disassembly tool 200 for realizing the disassembly and assembly of a heat sink 100 . The heat sink 100 includes a main body 110 and a plurality of threaded connectors 120 disposed on the main body 110 .

[0045] The body 110 is the main part of the radiator 100, which is mainly used to realize the functions of the radiator 100. Its specific structural form is not limited here. In practical applications, those skilled in the art can determine it according to the specific type of the radiator 100. Exemplarily, the radiator 100 can be a radiator used in computing devices such as servers. The radiator can be a metal block radiator, a liquid cooling radiator, etc., which can dissipate heat for the central processing unit (CPU) in the server. Correspondingly, the component that is docked with the radiator is the motherboard, and the radiator can be specifically installed on the motherboard. The threaded connector 120 is used to realize the installation and fixation of the body 110. The threaded connectors 120 are all equipped with a transmission tooth portion 121.

[0046] In the embodiment of the present application, the disassembly and assembly tool 200 includes an annular chain 210 and a power applying part 220. In a specific application, the annular chain 210 can be placed outside the radiator 100 and can be meshed with the transmission tooth parts 121 of each threaded connector 120, and the power applying part 220 is configured to drive the annular chain 210 to rotate.

[0047] When installing the radiator 100, the ring chain 210 can rotate under the action of the force applying part 220, and can drive each threaded connector 120 to rotate synchronously, so that the synchronous tightening of each threaded connector 120 can be achieved, and the consistency of the tightening degree of each threaded connector 120 can be better guaranteed, so that the force of the body 110 at each threaded connector 120 can be relatively uniform, which is conducive to ensuring the reliable connection and service life of the radiator 100. Taking the radiator 100 as an example of a radiator that can dissipate heat for the CPU in an application server, under the condition of ensuring the reliable connection of the radiator, the heat dissipation effect of the radiator 100 on the CPU can also be guaranteed, and the pressure of the radiator on each position of the CPU is relatively balanced, which can reduce damage to the CPU, such as damage to the CPU socket pins, and is also conducive to ensuring the normal operation of the server.

[0048] Furthermore, since the threaded connectors 120 of the heat sink 100 are tightened synchronously, compared with the separate tightening of the threaded connectors in the related art, the disassembly and assembly tool 200 provided in the embodiment of the present application can also improve the installation efficiency of the heat sink 100 and can greatly save installation time.

[0049] It should be understood that the disassembly tool 200 can also be used to disassemble the radiator 100. When the radiator 100 is disassembled, the circular chain 210 drives the threaded connectors 120 to rotate synchronously under the action of the power applying part 220. Therefore, the disassembly efficiency of the radiator 100 can also be improved; in this way, when the radiator 100 is found to be damaged and needs to be replaced, the efficiency of disassembly, assembly and replacement of the entire radiator 100 can be improved.

[0050] In the embodiment of the present application, the annular chain 210 and the power applying part 220 can be reused, and will not lead to an increase in the cost of disassembling and assembling the radiator 100 .

[0051] The “ring” in the ring chain 210 means that the chain is in a ring shape during the process of disassembling and assembling the radiator 100. The specific shape of the ring chain 210 is related to the number and distribution position of the threaded connectors 120. Figure 2 and Figure 4 In the implementation mode, there are four threaded connectors 120, and the four threaded connectors 120 are respectively arranged at the four corners of the body 110. In this case, the ring chain 210 can basically present a rectangular ring. When the number of the threaded connectors 120 is three, the ring chain 210 can basically present a triangular ring.

[0052] In some implementations, the power applying part 220 may directly drive the ring chain 210 to rotate, so that the rotation of the ring chain 210 drives each threaded connector 120 to rotate. Figure 3 At this time, the power applying part 220 may be provided with a driving tooth portion 223, which may mesh with the ring chain 210, and the ring chain 210 may rotate under the action of the driving tooth portion 223. Then, based on the meshing of the ring chain 210 with the transmission tooth portions 121 of each threaded connector 120, the rotation of the ring chain 210 may drive each threaded connector 120 to rotate.

[0053] In this implementation, each threaded connector 120 of the radiator 100 does not need to be configured with a structure that matches the power application part 220, and the structural form of the threaded connector 120 and the radiator 100 can be relatively simple. In addition, there is no need to consider the problem of thread slippage caused by the direct action of the power application part and the threaded connector in the related art. In other words, in this implementation, the power application part 220 and the ring chain 210 are matched with teeth and grooves, the transmission reliability is higher, the driving tooth part 223 and the ring chain 210 are not easy to be damaged, and it is more conducive to ensuring the smooth driving of each threaded connector 120.

[0054] In other implementations, the power applying part 220 may drive one of the threaded connectors 120 to rotate, and then the transmission tooth portion 121 of the threaded connector 120 indirectly drives the annular chain 210 to rotate, and then the annular chain 210 drives the transmission tooth portions 121 of the remaining threaded connectors 120 to rotate.

[0055] In a specific example, Figure 1 and Figure 2 As shown, the threaded connector 120 may be provided with a rotation driving groove 121a. The power applying portion 220 may include a force applying rod 221. The force applying rod 221 has a force applying end ( Figure 1 The force-applying end can be inserted into the rotation driving groove 121a. When the force-applying rod 221 rotates, the threaded connector 120 equipped with the rotation driving groove 121a can be driven to rotate through the cooperation between the force-applying end and the rotation driving groove 121a.

[0056] The aforementioned threaded connectors 120 may only partially be provided with the rotation drive groove 121a, for example, only one threaded connector 120 may be provided with the rotation drive groove 121a, while the remaining threaded connectors 120 may not be provided with the rotation drive groove 121a, so that the structure of some threaded connectors 120 can be simplified, and then the structure of the entire radiator 100 can be simplified. Of course, the aforementioned threaded connectors 120 may also all be provided with the rotation drive groove 121a; in this way, even if the rotation drive groove 121a of one threaded connector 120 is damaged, the force rod 221 can still drive the other threaded connectors 120 to drive the ring chain 210 to rotate, and it will not affect the normal disassembly and assembly of the radiator 100.

[0057] Here, the embodiment of the present application does not limit the structural form of the rotation drive slot 121a. In practical applications, those skilled in the art can determine it according to actual needs, as long as it can meet the requirements of use. For example, the rotation drive slot 121a can be a slot body with a non-circular cross-section such as a straight slot, a cross slot, a hexagonal slot, etc., and the structural form of the force-applying end only needs to match the rotation drive slot 121a, which will not be described in detail here.

[0058] The power applying unit 220 may be an automatic component to reduce the labor intensity of the staff. Figure 1 The power applying part 220 may further include a driving element 222 , which may be, for example, a motor, a pneumatic element, a hydraulic element, etc., which may be connected to the force applying rod 221 to drive the force applying rod 221 to rotate.

[0059] In some optional implementations, the disassembly and assembly tool 200 provided in the embodiment of the present application may further include a frame 230, and the power application unit 220 may be specifically installed on the frame 230, so as to realize the integrated assembly of the disassembly and assembly tool 200 through the frame 230. The specific structural form of the frame 230 is not limited here. In actual applications, those skilled in the art may determine it according to specific needs, as long as it can meet the requirements of use. For example, Figure 1 As shown, the rack 230 may be a panel rack.

[0060] The disassembly and assembly tool 200 may further include a control switch 231 disposed on the frame 230 for controlling the driving element 222. The control switch 231 and the power applying part 220 may be connected in communication, and the control switch 231 may be used to control the start and stop of the power applying part 220. Corresponding to the installation and removal of the radiator 100, the number of the control switches 231 may be two, one of which is an installation start switch, and the other of which is a removal start switch. Taking the driving element 222 as an example, when the installation start switch is pressed, the motor may rotate forward to drive each threaded connector 120 to rotate in a direction of gradually increasing screw-in depth through the ring chain 210, thereby realizing the installation and fixation of the radiator 100; when the removal start switch is pressed, the motor may rotate in reverse to drive each threaded connector 120 to rotate in a direction of gradually decreasing screw-in depth through the ring chain 210, thereby realizing the removal of the radiator 100.

[0061] The rack 230 may also be configured with a plurality of positioning portions 240 , each positioning portion 240 being used to position the relative position of the body 110 and the rack 230 , thereby improving the stability of the disassembly and assembly tool 200 provided in the embodiment of the present application when disassembling or installing the radiator 100 .

[0062] like Figure 1 As shown, the positioning portion 240 may include a positioning rod 241 and a pressing head 242 disposed on the positioning rod 241. The positioning rod 241 is used to contact the outer peripheral wall of the body 110. In this way, through the cooperation of multiple positioning rods 241 and the body 110, the body 110 can be clamped and fixed between the positioning rods 241 to reduce the possibility of the body 110 moving relative to the disassembly and assembly tool 200 in a plane perpendicular to the axial direction of the positioning rod 241. The pressing head 242 is used to contact the body 110 along the axial direction of the positioning rod 241 to locate the axial installation position of the body 110 relative to the positioning rod 241.

[0063] The pressure head 242 and the positioning rod 241 may be an integral structure formed in one piece. Alternatively, the pressure head 242 and the positioning rod 241 may be processed separately and then assembled, and the specific assembly method includes but is not limited to welding, interference fit, bonding, threaded connection, etc., as long as the reliability of the connection can be guaranteed.

[0064] The pressure head 242 may be an annular protrusion. In this case, the pressure head 242 may be arranged around the positioning rod 241. Alternatively, the pressure head 242 may also be distributed at a local position on the circumference of the positioning rod 241, such as Figure 1As shown, at this time, the pressure head 242 can be distributed at least on one side (also called the inner side) of the outer peripheral wall of the positioning rod 241 facing the radiator 100, so as to facilitate the pressure head 242 to press the radiator 100, and reduce the volume of the pressure head 242, so as to achieve lightweight. As for the axial installation position of the pressure head 242 on the positioning rod 241, it can be determined in combination with the axial size of the radiator 100 on the positioning rod 241.

[0065] In some optional implementations, such as Figure 5 As shown, the body 110 may be provided with a mounting hole 111. The threaded connector 120 may include a rod 122, and the rod 122 may be provided with a threaded hole 122a extending along its axial direction, that is, the threaded connector 120 is a nut, and accordingly, a component that needs to be docked with the body 110 (such as a main board) may be installed with a stud. The rod 122 may be provided with a transmission tooth portion 121 and a baffle portion 123, and the baffle portion 123 and the transmission tooth portion 121 may be arranged at intervals along the axial direction of the rod 122.

[0066] Along the axial direction of the mounting hole 111, the projection of the baffle 123 can be located inside the mounting hole 111, and at least part of the projection of the transmission tooth portion 121 can be located outside the mounting hole 111. In this way, the baffle 123 can pass through the mounting hole 111, while the transmission tooth portion 121 cannot pass through the mounting hole 111. After installation, the transmission tooth portion 121 and the baffle portion 123 can be located on both sides of the axial direction of the mounting hole 111, respectively.

[0067] The heat sink 100 may further include a gasket 130 and an elastic member 140. Along the axial direction of the mounting hole 111, the projection of the gasket 130 can cover the mounting hole 111. The gasket 130 may be made of a material having certain elastic properties, such as rubber, so that after the threaded connector 120 is installed in place, the inner hole of the gasket 130 may be expanded by applying an external force to the gasket 130, so that the gasket 130 can pass through the baffle 123, and then the external force applied to the gasket 130 is released, and the inner hole of the gasket 130 may be contracted again, so that the gasket 130 may be located between the baffle portion 123 and the body 110 to axially limit the baffle 123. The elastic member 140 may be located between the transmission tooth portion 121 and the body 110, and is used to axially limit the transmission tooth portion 121. The elastic member 140 may be a spring, which has a certain axial dimension and can better adapt to the axial spacing between the transmission tooth portion 121 and the body 110. Of course, the elastic member 140 may also be an elastomer made of a material having certain elastic properties such as rubber, that is, the elastic member 140 may also be replaced by the gasket 130 mentioned above, which is also feasible.

[0068] The cooperation between the elastic member 140 and the gasket 130 can improve the installation stability of the threaded connector 120 on the main body 110, and can largely avoid the threaded connector 120 from tipping over or falling over, so that the threaded connector 120 can stably cooperate with the ring chain 210.

[0069] The baffle plate 123 may be an annular plate. Alternatively, the baffle plate 123 may include a plurality of sub-plates, and each sub-plate may be spaced and distributed around the rod portion 122 .
