Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology, and in particular to a heat dissipation structure and a server device. Background Art

[0002] Edge microservers integrate data processing, network communication, data storage, and application execution capabilities. They receive sensory data and requests transmitted by edge devices, return the results to edge devices after calculation and analysis, and control edge devices. Since edge microservers are usually deployed on the edge side with changing environments, in order to adapt to these complex scenarios, passive heat dissipation of the shell is generally adopted, and they are often placed in a closed or sealed box environment to cope with various harsh external environmental conditions.

[0003] However, this approach makes it difficult for traditional passive cooling solutions to meet the growing cooling needs of edge microservers, thus limiting the full performance of the server. In addition, in the initial design stage of some edge microserver models, the cooling system is configured based on the cooling needs of low-power components; but in subsequent practical applications, these low-power components are often replaced with higher-power components for performance improvement; for example, the power consumption of a hard drive originally designed for the M.2 interface is usually maintained at around 3-4 watts, but if it is replaced with an M.2 accelerator card, its thermal design power consumption (TDP) can jump to 15 watts, which undoubtedly poses a severe challenge to the original internal cooling design.

[0004] In order to effectively improve the heat dissipation efficiency of the edge server, it is particularly necessary to add a heat dissipation module in the sealed box. However, due to the different sizes and shapes of edge microservers and the different sizes of various sealed boxes, it is impossible to ensure the heat dissipation effect while achieving compatibility and adaptation of the heat dissipation module with edge microservers and sealed boxes of different sizes and shapes. Summary of the invention

[0005] In view of this, the present invention provides a heat dissipation structure and a server device to solve the problem that the heat dissipation module cannot achieve compatibility and adaptation with edge microservers and sealed boxes of different sizes and shapes while ensuring the heat dissipation effect.

[0006] In the first aspect, the present invention provides a heat dissipation structure, including a first heat dissipation plate, a second heat dissipation plate, an elastic member and a heat-conductive telescopic structure; the first heat dissipation plate is used to be attached to a heat-generating component; the heat-generating component is arranged in a shell; the second heat dissipation plate is used to be attached to the inner wall of the shell; the second heat dissipation plate has a first position close to the first heat dissipation plate, and a second position away from the first heat dissipation plate; the elastic member is arranged between the first heat dissipation plate and the second heat dissipation plate; the heat-conductive telescopic structure is arranged between the second heat dissipation plate and the first heat dissipation plate, and is suitable for conducting the heat of the first heat dissipation plate to the second heat dissipation plate; when the second heat dissipation plate is in the first position, the elastic member and the heat-conductive telescopic structure are both in a shortened state; when the second heat dissipation plate is in the second position, the elastic member and the heat-conductive telescopic structure are both in an extended state.

[0007] Since the second heat sink has a first position close to the first heat sink, and a second position far from the first heat sink; through the setting of the elastic member, the present application can dynamically adjust the relative distance between the first heat sink and the second heat sink according to the actual spacing between the heat-generating component and the shell, realizing the adaptive adjustment function of the heat dissipation structure, so that it can be widely adapted to heat-generating components and shells of different sizes, effectively avoiding the disadvantages of the traditional heat dissipation scheme that the shell cannot be directly contacted due to the difference in specifications of the heat-generating components, and the shell needs to be frequently replaced, thereby significantly reducing the mold development and manufacturing costs; through the setting of the heat-conducting telescopic structure, the length of the heat sink can be automatically adjusted as the spacing between the first heat sink and the second heat sink changes, and whether the second heat sink is in the first position or the second position, it can ensure that the heat is efficiently transferred from the first heat sink to the second heat sink, thereby realizing the effective transfer of heat from the heat-generating component to the shell. This dynamic adjustment mechanism not only ensures the continuity of the heat dissipation path, promotes the effective transfer of heat, but also optimizes the efficiency of heat transfer, ensures the efficient heat dissipation of the heat-generating component in a closed environment, reduces the dependence on additional heat dissipation equipment, and significantly saves costs.

[0008] In an optional embodiment, the thermally conductive telescopic structure includes a thermally conductive telescopic tube and a liquid storage tube; the two ends of the thermally conductive telescopic tube are respectively connected to the second heat sink and the first heat sink; and a liquid storage cavity is provided in the thermally conductive telescopic tube, and the liquid storage cavity is filled with a conductive medium; and when the thermally conductive telescopic tube is in a shortened state, the volume of the liquid storage cavity becomes smaller; when the thermally conductive telescopic tube is in an extended state, the volume of the liquid storage cavity becomes larger; and the liquid storage tube is connected to the liquid storage cavity.

[0009] By providing a liquid storage chamber in the thermally conductive telescopic tube and filling the liquid storage chamber with a conductive medium, the high thermal conductivity of the conductive medium is utilized to effectively improve the heat transfer rate in the thermally conductive telescopic tube, thereby enhancing the thermal conduction efficiency of the thermally conductive telescopic tube; and because the volume of the liquid storage chamber changes with the length of the thermally conductive telescopic tube, through the provision of the liquid storage tube, when the thermally conductive telescopic tube is in a shortened state, the volume of the liquid storage chamber will decrease accordingly. At this time, the conductive medium in the liquid storage chamber can smoothly flow into the liquid storage tube, thereby avoiding problems such as increased medium pressure or overflow caused by reduced volume; not only the stability of the thermal conduction performance of the thermally conductive telescopic tube during the length change is ensured, but also the flexibility and reliability of the entire heat dissipation system are further improved.

[0010] In an optional embodiment, a piston is provided in the liquid storage cylinder, and the piston is slidably and sealingly connected in the liquid storage cylinder. When the thermally conductive telescopic cylinder is in a shortened state, the piston slides toward an end away from the thermally conductive telescopic cylinder; when the thermally conductive telescopic cylinder is in an extended state, the piston slides toward an end close to the thermally conductive telescopic cylinder.

[0011] By arranging a piston in the liquid storage cylinder, when the thermally conductive telescopic cylinder is in a shortened state, the piston slides toward the end away from the thermally conductive telescopic cylinder, and the volume of the liquid storage cylinder becomes larger, thereby providing sufficient storage space for the excess conductive medium flowing out of the thermally conductive telescopic cylinder, and the conductive medium can flow from the thermally conductive telescopic cylinder into the liquid storage cylinder, and the liquid storage cylinder stores the excess conductive medium, ensuring that the liquid storage cylinder can effectively absorb and store the conductive medium that is no longer needed due to the shortening of the thermally conductive telescopic cylinder, thereby preventing waste and loss of the conductive medium; when the thermally conductive telescopic cylinder is in an extended state, the piston slides toward the end close to the thermally conductive telescopic cylinder, and the internal volume of the liquid storage cylinder is correspondingly reduced, so that the excess conductive medium previously stored in the liquid storage cylinder flows back into the thermally conductive telescopic cylinder, ensuring that an appropriate amount of conductive medium is always maintained in the liquid storage cavity, thereby maintaining an efficient heat dissipation effect. The arrangement of the piston realizes a dynamic balance of the conductive medium between the thermally conductive telescopic cylinder and the liquid storage cylinder, and also ensures that the heat dissipation system can maintain optimal heat dissipation performance under various working conditions.

[0012] In an optional embodiment, the thermally conductive telescopic cylinder includes a thermally conductive outer cylinder and a thermally conductive inner cylinder; the thermally conductive outer cylinder is fixed on the first heat sink; the liquid storage cavity is arranged in the thermally conductive outer cylinder; one end of the thermally conductive inner cylinder is fixed to the second heat sink, and the other end is extended into the liquid storage cavity and is slidably and sealedly connected to the liquid storage cavity.

[0013] By setting the liquid storage cavity in the heat-conducting outer cylinder, and extending one end of the heat-conducting inner cylinder in the liquid storage cavity, and sliding and sealingly connecting with the liquid storage cavity, when the spacing between the first heat sink and the second heat sink changes, the heat-conducting inner cylinder can adjust its length extending into the liquid storage cavity accordingly, thereby smoothly realizing the telescopic function of the heat-conducting telescopic cylinder. And because the heat-conducting inner cylinder is extended in the liquid storage cavity, direct contact between the conductive medium and the heat-conducting inner cylinder can be achieved, which not only ensures that the heat transfer path is unobstructed, but also significantly improves the heat conduction efficiency, so that heat can be conducted more quickly and efficiently through the heat-conducting inner cylinder.

[0014] In an optional embodiment, the elastic member is sleeved on the outer circumference of the heat-conductive telescopic cylinder, one end of which is fixedly connected to the heat-conductive inner cylinder, and the other end is located above the liquid storage cylinder and fixedly connected to the heat-conductive outer cylinder.

[0015] By sleeved the elastic part on the outer circumference of the heat-conducting telescopic cylinder, with one end connected to the heat-conducting inner cylinder and the other end connected to the heat-conducting outer cylinder, the elastic expansion and contraction of the heat-conducting telescopic cylinder is realized, thereby realizing the elastic connection between the first heat sink and the second heat sink; and the connection between the elastic part and the heat-conducting outer cylinder is located above the liquid storage cylinder, which can avoid interference between the liquid storage cylinder and the elastic part; the connection layout of the internal components of the heat dissipation structure is optimized; not only the flexible and elastic expansion and contraction of the heat-conducting telescopic cylinder is realized, but also the coordinated operation between the internal components of the heat dissipation structure is ensured.

[0016] In an optional embodiment, the thermally conductive telescopic cylinder further includes a sealing assembly, and one end of the thermally conductive inner cylinder connected to the thermally conductive outer cylinder is a sealing end, and the sealing end is sealedly connected to the thermally conductive outer cylinder through the sealing assembly.

[0017] By setting one end where the heat-conducting inner tube and the heat-conducting outer tube are connected as a sealing end, and connecting the sealing end to the heat-conducting outer tube through a sealing assembly, not only a reliable sealing connection between the heat-conducting inner tube and the heat-conducting outer tube is ensured, effectively preventing the leakage of the conductive medium during operation, but also significantly improving the service life and reliability of the entire heat dissipation structure.

[0018] In an optional embodiment, the end of the elastic member close to the second heat dissipation plate is the first end, and the end close to the first heat dissipation plate is the second end, the first end is fixedly connected to the heat-conducting inner cylinder, and the second end is fixedly connected to the heat-conducting outer cylinder; the distance between the first end and the sealing end is greater than the distance between the first end and the heat-conducting outer cylinder.

[0019] Since the distance between the first end and the sealing end is greater than the distance between the first end and the heat-conducting outer cylinder, when the heat-conducting telescopic cylinder is extended to its maximum length, sufficient space is reserved between the first end and the sealing end, which effectively prevents the heat-conducting inner cylinder from accidentally slipping off or separating from the heat-conducting outer cylinder, ensuring that the heat-conducting inner cylinder can be stably maintained inside the heat-conducting outer cylinder when the heat-conducting telescopic cylinder is in the extended state; not only the integrity and stability of the heat dissipation structure are guaranteed, but also the risk of heat dissipation performance degradation or failure caused by the falling off of the heat-conducting inner cylinder is avoided, ensuring the efficient and stable operation of the heat dissipation structure.

[0020] In an optional embodiment, one or more fixed grooves are provided on the outer periphery of the heat-conducting inner cylinder, and the plurality of fixed grooves are arranged in sequence along the axial direction of the heat-conducting inner cylinder; the sealing assembly includes one or more sealing rings, the sealing rings correspond one-to-one to the fixed grooves, the sealing rings are fixed in the fixed grooves, and the outer wall of the sealing ring abuts against the inner wall of the heat-conducting outer cylinder.

[0021] By setting the fixing groove, not only a precise installation position is provided for the sealing ring, but also it is ensured that when the heat-conducting inner cylinder and the heat-conducting outer cylinder slide relative to each other, the position of the sealing ring can remain stable to prevent it from being offset or misplaced due to sliding; and because the outer wall of the sealing ring abuts against the inner wall of the heat-conducting outer cylinder, the contact area between the sealing ring and the heat-conducting outer cylinder is increased, the sealing efficiency between the two is improved, and the risk of leakage of the conductive medium at the connection between the heat-conducting inner cylinder and the heat-conducting outer cylinder is effectively reduced; and by setting a plurality of sealing rings, not only the sealing effect of the connection between the heat-conducting inner cylinder and the heat-conducting outer cylinder is further improved, but also the risk of a decrease in the overall sealing performance due to the failure of a single sealing ring is significantly reduced.

[0022] In an optional embodiment, the second heat plate and the first heat plate are arranged parallel to each other; the heat conductive telescopic structure is provided with two groups, and the two groups of heat conductive telescopic structures are arranged on both sides of the first heat plate relatively along a first direction; the two heat conductive telescopic cylinders are arranged on both sides of the first heat plate relatively along a second direction, and the two liquid storage cylinders are arranged parallel to the first heat plate; a connecting hole is provided on the side wall of the heat conductive outer cylinder, and the connecting hole is arranged on a side of the heat conductive outer cylinder close to the first heat plate and is spaced apart from the first heat plate; the liquid storage cylinder is spaced apart from the first heat plate, and the liquid storage cylinder is connected to the connecting hole and is detachably connected to the heat conductive outer cylinder; the liquid storage cylinder extends along the second direction, and a piston is sealedly connected to the end of the liquid storage cylinder facing away from the connecting hole, and the piston is slidably arranged in the liquid storage cylinder along the second direction; in the second direction, the length of the liquid storage cylinder is less than the length of the first heat plate; the first direction and the second direction are perpendicular to each other.

[0023] Since the two sets of heat-conducting telescopic structures are arranged relatively on both sides of the first heat sink along the first direction, the stability of the connection between the first heat sink and the second heat sink can be enhanced, and the heat transfer path between the first heat sink and the second heat sink can be optimized, thereby improving the heat dissipation performance; since the liquid storage cylinder and the first heat sink and the second heat sink are arranged parallel to each other, when the second heat sink and the first heat sink are close to each other and are in the first position, interference between the liquid storage cylinder and the second heat sink can be avoided, thereby ensuring the smoothness of the first heat sink and the second heat sink during relative movement. Since the length of the liquid storage cylinder in the second direction is less than the length of the first heat sink in the second direction, not only does it provide additional protection space for the liquid storage cylinder, reducing the risk of collision between the external structure and the liquid storage cylinder, but it also significantly reduces the overall space occupied by the heat dissipation structure, thereby improving the space utilization and durability of the heat dissipation structure.

[0024] In an optional embodiment, a first heat dissipation sticker is further included, one side of which is adhered to a side of the first heat dissipation plate facing away from the second heat dissipation plate, and the other side of which is suitable for being adhered to the heat-generating component.

[0025] By setting the first heat sink, a close fit between the first heat sink and the heat-generating component can be ensured, which not only greatly reduces the thermal resistance in the heat transfer process, but also enhances the thermal conduction efficiency of the contact surface, thereby ensuring that the heat generated by the heat-generating component can be quickly and effectively transferred to the first heat sink, thereby achieving effective heat dissipation through the heat dissipation structure.

[0026] In an optional embodiment, a second heat dissipation sticker is further included, one side of the second heat dissipation sticker is adhered to the side of the second heat dissipation plate facing away from the first heat dissipation plate, and the other side is suitable for being adhered to the housing.

[0027] By setting up the second heat sink, a close fit between the second heat sink and the shell can be ensured, which not only greatly reduces the thermal resistance in the heat transfer process, but also enhances the thermal conduction efficiency of the contact surface, thereby ensuring that the heat transferred to the second heat sink can be quickly and effectively transferred to the shell, thereby achieving effective heat dissipation through the shell.

[0028] In a second aspect, the present invention further provides a server device, comprising a sealed box, a server body and the above-mentioned heat dissipation structure; the server body is arranged in the sealed box; and the above-mentioned heat dissipation structure is arranged between the server body and the sealed box.

[0029] Since the heat dissipation structure is arranged between the sealed box and the server body, the adaptive adjustment function of the heat dissipation structure makes it widely adaptable to server bodies and sealed boxes of different sizes and specifications, effectively avoiding the disadvantage of frequent replacement of the sealed box due to the difference in specifications of the server body and the inability to directly contact the sealed box, thereby significantly reducing the mold development and manufacturing costs; and the heat dissipation structure realizes the effective transfer of heat from the heat-generating components to the shell, ensuring the efficient heat dissipation of the heat-generating components in a closed environment, reducing the dependence on additional heat dissipation equipment, and saving heat dissipation costs.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0038] According to an embodiment of the present invention, on the one hand, a heat dissipation structure is provided, including a first heat dissipation plate 1, a second heat dissipation plate 2, an elastic member 3 and a thermally conductive telescopic structure 4; the first heat dissipation plate 1 is used to be attached to a heat-generating component; the heat-generating component is arranged in a shell; the second heat dissipation plate 2 is used to be attached to the inner wall of the shell; the second heat dissipation plate 2 has a first position close to the first heat dissipation plate 1, and a second position away from the first heat dissipation plate 1; the elastic member 3 is arranged between the first heat dissipation plate 1 and the second heat dissipation plate 2; the thermally conductive telescopic structure 4 is arranged between the second heat dissipation plate 2 and the first heat dissipation plate 1, and is suitable for conducting the heat of the first heat dissipation plate 1 to the second heat dissipation plate 2; when the second heat dissipation plate 2 is in the first position, the elastic member 3 and the thermally conductive telescopic structure 4 are both in a shortened state; when the second heat dissipation plate 2 is in the second position, the elastic member 3 and the thermally conductive telescopic structure 4 are both in an extended state.

[0039] Since the second heat sink 2 has a first position close to the first heat sink 1 and a second position far away from the first heat sink 1; through the setting of the elastic member 3, the present application can dynamically adjust the relative distance between the first heat sink 1 and the second heat sink 2 according to the actual spacing between the heat-generating component and the shell, realizing the adaptive adjustment function of the heat dissipation structure, so that it can be widely adapted to heat-generating components and shells of different sizes, effectively avoiding the disadvantages of the traditional heat dissipation scheme that the shell cannot be directly contacted due to the difference in specifications of the heat-generating components, and the shell needs to be frequently replaced, thereby significantly reducing the cost of mold development and manufacturing; through the setting of the heat-conducting telescopic structure 4, the length of the heat-conducting telescopic structure 4 can be automatically adjusted as the spacing between the first heat sink 1 and the second heat sink 2 changes, and whether the second heat sink 2 is in the first position or the second position, it can ensure that the heat is efficiently transferred from the first heat sink 1 to the second heat sink 2, thereby realizing the effective transfer of heat from the heat-generating component to the shell. This dynamic adjustment mechanism not only ensures the continuity of the heat dissipation path, promotes the effective transfer of heat, but also optimizes the efficiency of heat transfer, ensures the efficient heat dissipation of the heat-generating component in a closed environment, reduces the dependence on additional heat dissipation equipment, and significantly saves costs.

[0040] In one embodiment, the thermally conductive telescopic structure 4 includes a thermally conductive telescopic tube 41 and a liquid storage tube 42; the two ends of the thermally conductive telescopic tube 41 are respectively connected to the second heat sink 2 and the first heat sink 1; and a liquid storage cavity is provided in the thermally conductive telescopic tube 41, and the liquid storage cavity is filled with a conductive medium; and when the thermally conductive telescopic tube 41 is in a shortened state, the volume of the liquid storage cavity becomes smaller; when the thermally conductive telescopic tube 41 is in an extended state, the volume of the liquid storage cavity becomes larger; the liquid storage tube 42 is connected to the liquid storage cavity.

[0041] By providing a liquid storage chamber in the thermally conductive telescopic tube 41 and filling the liquid storage chamber with a conductive medium, the high thermal conductivity of the conductive medium is utilized to effectively improve the heat transfer rate in the thermally conductive telescopic tube 41, thereby enhancing the thermal conduction efficiency of the thermally conductive telescopic tube 41; and because the volume of the liquid storage chamber changes with the length of the thermally conductive telescopic tube 41, through the provision of the liquid storage tube 42, when the thermally conductive telescopic tube 41 is in a shortened state, the volume of the liquid storage chamber will decrease accordingly. At this time, the conductive medium in the liquid storage chamber can flow smoothly into the liquid storage tube 42, thereby avoiding problems such as increased medium pressure or overflow caused by reduced volume; not only ensures the stability of the thermal conduction performance of the thermally conductive telescopic tube 41 during the length change, but also further improves the flexibility and reliability of the entire heat dissipation system.

[0042] In a specific embodiment, the conductive medium is a highly conductive liquid.

[0043] Preferably, a first cooling fin can also be arranged between the thermally conductive telescopic tube 41 and the first heat sink 1, the cold end of the first cooling fin being connected to the first heat sink 1, and the hot end being connected to the thermally conductive telescopic tube 41; it can actively absorb heat from the first heat sink 1, and transfer it to the thermally conductive telescopic tube 41 through the thermoelectric effect, and provide a continuous cold source for the first heat sink 1, effectively reducing its temperature, thereby achieving active cooling of the heat-generating components; a second cooling fin can also be arranged between the thermally conductive telescopic tube 41 and the second heat sink 2, the cold end of the second cooling fin being connected to the thermally conductive telescopic tube 41, and the hot end being connected to the second heat sink 2; it can actively absorb heat from the thermally conductive telescopic tube 41, and transfer it to the second heat sink 2 through the thermoelectric effect, and then the second heat sink 2 transfers the heat to the shell for heat dissipation; the second cooling fin not only provides a stable cold source for the thermally conductive telescopic tube 41, significantly reducing its temperature, but also greatly improves the heat transfer efficiency, ensuring the stability and reliability of the system under high-load operation. Specifically, the power supply of the first refrigeration fin is set on the first heat sink 1, and the power supply of the second refrigeration fin is set on the second heat sink 2, ensuring that no matter whether the second heat sink 2 is in the first position or the second position, the first refrigeration fin and the second refrigeration fin are not affected by the change of their position and can obtain a stable and continuous supply of electricity.

[0044] In one embodiment, a piston 421 is provided in the liquid storage cylinder 42, and the piston 421 is slidably and sealingly connected in the liquid storage cylinder 42. When the thermally conductive telescopic cylinder 41 is in a shortened state, the piston 421 slides toward an end away from the thermally conductive telescopic cylinder 41; when the thermally conductive telescopic cylinder 41 is in an extended state, the piston 421 slides toward an end close to the thermally conductive telescopic cylinder 41.

[0045] By arranging the piston 421 in the liquid storage cylinder 42, when the thermally conductive telescopic cylinder 41 is in a shortened state, the piston 421 slides toward the end away from the thermally conductive telescopic cylinder 41, and the volume of the liquid storage cylinder 42 becomes larger, thereby providing sufficient storage space for the excess conductive medium flowing out of the thermally conductive telescopic cylinder 41. The conductive medium can flow from the thermally conductive telescopic cylinder 41 into the liquid storage cylinder 42, and the liquid storage cylinder 42 stores the excess conductive medium, ensuring that the liquid storage cylinder 42 can effectively absorb and store the conductive medium that is no longer needed due to the shortening of the thermally conductive telescopic cylinder 41, thereby preventing the waste and loss of the conductive medium; when the thermally conductive telescopic cylinder 41 is in an extended state, the piston 421 slides toward the end close to the thermally conductive telescopic cylinder 41, correspondingly reducing the internal volume of the liquid storage cylinder 42, so that the excess conductive medium previously stored in the liquid storage cylinder 42 flows back into the thermally conductive telescopic cylinder 41, ensuring that an appropriate amount of conductive medium is always maintained in the liquid storage cavity, thereby maintaining an efficient heat dissipation effect. The arrangement of the piston 421 achieves a dynamic balance of the conductive medium between the heat-conducting telescopic cylinder 41 and the liquid storage cylinder 42, and also ensures that the heat dissipation system can maintain optimal heat dissipation performance under various working conditions.

[0046] In one embodiment, the thermally conductive telescopic cylinder 41 includes a thermally conductive outer cylinder 411 and a thermally conductive inner cylinder 412; the thermally conductive outer cylinder 411 is fixed on the first heat sink 1; the liquid storage cavity is arranged in the thermally conductive outer cylinder 411; one end of the thermally conductive inner cylinder 412 is fixed to the second heat sink 2, and the other end is extended into the liquid storage cavity and is slidably and sealedly connected to the liquid storage cavity.

[0047] By setting the liquid storage cavity in the heat-conducting outer cylinder 411, and extending one end of the heat-conducting inner cylinder 412 into the liquid storage cavity, and slidingly sealingly connected with the liquid storage cavity, when the distance between the first heat sink 1 and the second heat sink 2 changes, the heat-conducting inner cylinder 412 can adjust its length extending into the liquid storage cavity accordingly, thereby smoothly realizing the telescopic function of the heat-conducting telescopic cylinder 41. And because the heat-conducting inner cylinder 412 is extended into the liquid storage cavity, direct contact between the conductive medium and the heat-conducting inner cylinder 412 can be achieved, which not only ensures that the heat transfer path is unobstructed, but also significantly improves the heat conduction efficiency, so that heat can be conducted more quickly and efficiently through the heat-conducting inner cylinder 412.

[0048] In a specific embodiment, the heat-conducting outer tube 411 is a cylindrical tube, and the interior of the heat-conducting outer tube 411 is a hollow structure to form a liquid storage cavity. The bottom of the hollow structure of the heat-conducting outer tube 411 is directly connected to the first heat sink 1, and is enclosed with the first heat sink 1 to form a liquid storage cavity, thereby ensuring direct contact between the first heat sink 1 and the conductive medium, and ensuring the directness and efficiency of heat transfer.

[0049] In a specific implementation, the heat-conducting inner cylinder 412 is a round copper column, which can achieve heat conduction.

[0050] In a specific implementation, the conductive medium is completely filled in the entire liquid storage cavity, which not only maximizes the use of the volume of the liquid storage cavity, but also ensures sufficient contact between the conductive medium and the first heat sink 1 and the heat-conducting inner cylinder 412 .

[0051] In another implementation of the present embodiment, the heat-conducting inner cylinder 412 may be a cylindrical cylinder, and the interior of the heat-conducting inner cylinder 412 may be a hollow structure, the top of the hollow structure of the heat-conducting inner cylinder 412 may be directly connected to the second heat sink 2, and the bottom of the heat-conducting inner cylinder 412 may be extended inside the hollow structure of the heat-conducting outer cylinder 411, and the hollow structures of the two may be interconnected to form a continuous heat-conducting channel, and the heat-conducting channel may be enclosed with the first heat sink 1 and the second heat sink 2 to form a liquid storage cavity, and the conductive medium in the liquid storage cavity may be in direct contact with the first heat sink 1 and the second heat sink 2, and may exchange heat with the first heat sink 1 and the second heat sink 2.

[0052] In one embodiment, the elastic member 3 is sleeved on the outer circumference of the thermally conductive telescopic cylinder 41 , one end of which is fixedly connected to the thermally conductive inner cylinder 412 , and the other end of which is located above the liquid storage cylinder 42 and fixedly connected to the thermally conductive outer cylinder 411 .

[0053] By sleeved the elastic member 3 on the outer circumference of the heat-conducting telescopic tube 41, with one end connected to the heat-conducting inner tube 412 and the other end connected to the heat-conducting outer tube 411, the elastic expansion and contraction of the heat-conducting telescopic tube 41 is realized, thereby realizing the elastic connection between the first heat sink 1 and the second heat sink 2; and the connection between the elastic member 3 and the heat-conducting outer tube 411 is located above the liquid storage tube 42, which can avoid interference between the liquid storage tube 42 and the elastic member 3; the connection layout of the internal components of the heat dissipation structure is optimized; not only the flexible and elastic expansion and contraction of the heat-conducting telescopic tube 41 is realized, but also the coordinated operation between the internal components of the heat dissipation structure is ensured.

[0054] Specifically, the elastic member 3 is fixedly connected to the heat-conducting inner cylinder 412 through a first anchoring nail; and the elastic member 3 is fixedly connected to the heat-conducting outer cylinder 411 through a second anchoring nail.

[0055] In a specific embodiment, the elastic member 3 is a spring.

[0056] In another implementation of this embodiment, the elastic member 3 and the thermally conductive telescopic cylinder 41 may be spaced apart, and two ends of the elastic member 3 are respectively connected to the first heat sink 1 and the second heat sink 2 .

[0057] In one embodiment, the thermally conductive telescopic cylinder 41 further includes a sealing component 413 , and one end of the thermally conductive inner cylinder 412 connected to the thermally conductive outer cylinder 411 is a sealing end, and the sealing end is sealedly connected to the thermally conductive outer cylinder 411 through the sealing component 413 .

[0058] By setting one end connecting the heat-conducting inner cylinder 412 and the heat-conducting outer cylinder 411 as a sealing end, and connecting the sealing end and the heat-conducting outer cylinder 411 through the sealing assembly 413, not only a reliable sealing connection is ensured between the heat-conducting inner cylinder 412 and the heat-conducting outer cylinder 411, the leakage of the conductive medium during operation is effectively prevented, but also the service life and reliability of the entire heat dissipation structure are significantly improved.

[0059] In one embodiment, the end of the elastic member 3 close to the second heat dissipation plate 2 is the first end, and the end close to the first heat dissipation plate 1 is the second end. The first end is fixedly connected to the heat-conducting inner tube 412, and the second end is fixedly connected to the heat-conducting outer tube 411; the distance between the first end and the sealing end is greater than the distance between the first end and the heat-conducting outer tube 411.

[0060] Since the distance between the first end and the sealing end is greater than the distance between the first end and the heat-conducting outer cylinder 411, when the heat-conducting telescopic cylinder 41 is extended to its maximum length, sufficient space is reserved between the first end and the sealing end, which effectively prevents the heat-conducting inner cylinder 412 from accidentally slipping off or separating from the heat-conducting outer cylinder 411, thereby ensuring that the heat-conducting inner cylinder 412 can be stably maintained inside the heat-conducting outer cylinder 411 when the heat-conducting telescopic cylinder 41 is in the extended state; not only the integrity and stability of the heat dissipation structure are guaranteed, but also the risk of heat dissipation performance degradation or failure caused by the falling off of the heat-conducting inner cylinder 412 is avoided, thereby ensuring the efficient and stable operation of the heat dissipation structure.

[0061] In one embodiment, the outer periphery of the heat-conducting inner cylinder 412 is provided with one or more fixed grooves, and the plurality of fixed grooves are sequentially arranged along the axial direction of the heat-conducting inner cylinder 412; the sealing assembly 413 includes one or more sealing rings, and the sealing rings correspond to the fixed grooves one by one. The sealing rings are fixed in the fixed grooves, and the outer wall of the sealing ring abuts against the inner wall of the heat-conducting outer cylinder 411.

[0062] By setting the fixing groove, not only a precise installation position is provided for the sealing ring, but also it is ensured that when the heat-conducting inner cylinder 412 and the heat-conducting outer cylinder 411 slide relative to each other, the position of the sealing ring can remain stable to prevent it from being offset or misplaced due to sliding; and because the outer wall of the sealing ring abuts against the inner wall of the heat-conducting outer cylinder 411, the contact area between the sealing ring and the heat-conducting outer cylinder 411 is increased, the sealing efficiency between the two is improved, and the leakage risk of the conductive medium at the connection between the heat-conducting inner cylinder 412 and the heat-conducting outer cylinder 411 is effectively reduced; and by setting a plurality of sealing rings, not only the sealing effect of the connection between the heat-conducting inner cylinder 412 and the heat-conducting outer cylinder 411 is further improved, but also the risk of a decrease in the overall sealing performance due to the failure of a single sealing ring is significantly reduced.

[0063] In a specific implementation, the sealing ring is a sealing rubber ring.

[0064] In one embodiment, the second heat sink 2 and the first heat sink 1 are arranged parallel to each other; the heat conductive telescopic structure 4 is provided with two groups, and the two groups of heat conductive telescopic structures 4 are arranged on both sides of the first heat sink 1 in a first direction; the two heat conductive telescopic cylinders 41 are arranged on both sides of the first heat sink 1 in a second direction, and the two liquid storage cylinders 42 are arranged in parallel with the first heat sink 1; a connecting hole is provided on the side wall of the heat conductive outer cylinder 411, and the connecting hole is arranged on the side of the heat conductive outer cylinder 411 close to the first heat sink 1, and is connected to the first The heat sink 1 is arranged at intervals; the liquid storage cylinder 42 is arranged at intervals from the first heat sink 1, and the liquid storage cylinder 42 is connected to the connecting hole and is detachably connected to the heat-conducting outer cylinder 411; the liquid storage cylinder 42 extends along the second direction, and the end of the liquid storage cylinder 42 away from the connecting hole is sealed with a piston 421, and the piston 421 is slidably arranged in the liquid storage cylinder 42 along the second direction; in the second direction, the length of the liquid storage cylinder 42 is less than the length of the first heat sink 1; the first direction and the second direction are perpendicular to each other.

[0065] Since the two groups of heat-conducting telescopic structures 4 are arranged on both sides of the first heat sink 1 in a relative manner along the first direction, the stability of the connection between the first heat sink 1 and the second heat sink 2 can be enhanced, and the heat transfer path between the first heat sink 1 and the second heat sink 2 can be optimized, thereby achieving an improvement in heat dissipation performance; since the liquid storage cylinder 42 and the first heat sink 1 and the second heat sink 2 are arranged parallel to each other, when the second heat sink 2 and the first heat sink 1 are close to each other and are in the first position, interference between the liquid storage cylinder 42 and the second heat sink 2 can be avoided, thereby ensuring the smoothness of the first heat sink 1 and the second heat sink 2 during relative movement. Since the length of the liquid storage cylinder 42 in the second direction is less than the length of the first heat sink 1 in the second direction, not only does it provide additional protection space for the liquid storage cylinder 42, reducing the risk of collision between the external structure and the liquid storage cylinder 42, but it also significantly reduces the overall space occupied by the heat dissipation structure, thereby improving the space utilization and durability of the heat dissipation structure.

[0066] Specifically, the first heat sink 1 and the second heat sink 2 are both plate-shaped structures, which ensures that the first heat sink 1 can fit tightly with the heat-generating component, and the second heat sink 2 can fit tightly with the housing.

[0067] In a specific implementation, the liquid storage cylinder 42 is connected to the thermally conductive telescopic structure 4 via fasteners such as bolts.

[0068] In one embodiment, a first heat dissipation sticker 5 is further included. One side of the first heat dissipation sticker 5 is adhered to the side of the first heat dissipation plate 1 facing away from the second heat dissipation plate 2, and the other side is suitable for being adhered to the heat-generating component.

[0069] By setting the first heat dissipation sticker 5, a close fit between the first heat sink 1 and the heat-generating component can be ensured, which not only greatly reduces the thermal resistance in the heat transfer process, but also enhances the thermal conduction efficiency of the contact surface, thereby ensuring that the heat generated by the heat-generating component can be quickly and effectively transferred to the first heat sink 1, thereby achieving effective heat dissipation through the heat dissipation structure.

[0070] In one embodiment, a second heat dissipation sticker 6 is further included. One side of the second heat dissipation sticker 6 is adhered to the side of the second heat dissipation plate 2 facing away from the first heat dissipation plate 1, and the other side is suitable for being adhered to the housing.

[0071] By setting the second heat dissipation sticker 6, a close fit between the second heat dissipation plate 2 and the shell can be ensured, which not only greatly reduces the thermal resistance in the heat transfer process, but also enhances the thermal conduction efficiency of the contact surface, thereby ensuring that the heat transferred to the second heat dissipation plate 2 can be quickly and effectively transferred to the shell, thereby achieving effective heat dissipation through the shell.

[0072] According to an embodiment of the present invention, on the other hand, a server device is provided, comprising a sealed box, a server body and the above-mentioned heat dissipation structure; the server body is arranged in the sealed box; and the above-mentioned heat dissipation structure is arranged between the server body and the sealed box.

[0073] Since the heat dissipation structure is arranged between the sealed box and the server body, the adaptive adjustment function of the heat dissipation structure makes it widely adaptable to server bodies and sealed boxes of different sizes and specifications, effectively avoiding the disadvantage of frequent replacement of the sealed box due to the difference in specifications of the server body and the inability to directly contact the sealed box, thereby significantly reducing the mold development and manufacturing costs; and the heat dissipation structure realizes the effective transfer of heat from the heat-generating components to the shell, ensuring the efficient heat dissipation of the heat-generating components in a closed environment, reducing the dependence on additional heat dissipation equipment, and saving heat dissipation costs.

[0074] In a specific implementation, the server body is placed in a sealed box, and then the heat dissipation structure is placed on the server body, and the first heat dissipation plate 1 is fitted with the server body; then the cover of the sealed box is placed on the second heat dissipation plate 2 and fitted with the second heat dissipation plate 2, and the cover is covered on the sealed box. During this process, the spring and the heat-conductive telescopic structure 4 are both contracted and are in a shortened state, and the excess conductive medium in the heat-conductive telescopic structure 4 flows into the liquid storage cylinder 42.

[0075] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
