Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation structures, and in particular to a heat sink. In addition, the present invention also relates to an optical module device including the heat sink, a switch including the optical module device, and a server including the optical module device. Background Art

[0002] As the speed of optical modules increases rapidly, the overall power consumption of optical modules also increases rapidly. The presence of laser components inside optical modules places even more stringent requirements on heat dissipation.

[0003] In the current related technical solutions, the radiator is generally set up independently, and the radiator is pressed onto the surface of the optical module through the opening on the cage surface by a spring sheet, and the optical module contacts the radiator to achieve heat dissipation of the optical module. Since the radiator above each optical cage is independent, the cold plate needs to be set as an independent small cold plate. When the optical module is plugged in and out, the radiator will rise and fall, and the cold plate will rise and fall accordingly. For water-cooled components, more pipelines need to be set up to ensure the independent rise and fall of each independent cold plate, resulting in too many liquid cooling interfaces, which is easy to cause water leakage.

[0004] On the other hand, the air-cooled heat sink of the optical module is connected to the cold plate, and the heat is transferred to the cold plate through the heat pipe, thereby achieving heat dissipation of the optical module. However, during use, when the optical module is inserted and removed, the heat sink of the optical module will fluctuate; due to the presence of the heat pipe, this fluctuation is unevenly stressed, resulting in uneven contact force between the heat sink and the optical module, thus affecting the heat dissipation effect.

[0005] In summary, how to provide a heat sink that can prevent the heat sink from rising and falling as a whole during the plugging and unplugging of an optical module is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

The second heat sink component can remain fixed, effectively avoiding the ups and downs of the heat sink as a whole during the plugging and unplugging of the optical module.

[0097] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0098] The core of the present invention is to provide a heat sink. During actual use, the second heat sink component can be relatively close to or far away from the first heat sink component along the protruding direction of the first heat transfer structure or the second heat transfer structure; during the plugging and unplugging of the heating element, the first heat sink component rises and falls relative to the second heat sink component along the protruding direction of the first heat transfer structure or the second heat transfer structure, and does not affect the second heat sink component. The second heat sink component can remain fixed, effectively avoiding the overall fluctuation of the heat sink during the plugging and unplugging of the optical module.

[0099] Another core of the present invention is to provide an optical module device including the above-mentioned heat sink, a switch including the above-mentioned optical module device, and a server including the above-mentioned optical module device.

[0100] The present specific embodiment discloses a heat sink 01, comprising a first heat sink component 1, a second heat sink component 2 and a first elastic component 3: the first heat sink component 1 is provided with a first heat conducting surface for contacting a heating element and a first heat transfer structure 11; the first heat transfer structure 11 is protrudingly arranged on a side of the first heat sink component 1 facing the second heat sink component 2; the second heat sink component 2 is provided with a second heat conducting surface for contacting a cooling element and a second heat transfer structure 21; the second heat transfer structure 21 is protrudingly arranged on a side of the second heat sink component 2 facing the first heat sink component 1; the first heat sink component 1 and the second heat sink component 2 can be relatively close to or away from each other along the protruding direction of the first heat transfer structure 11 or the second heat transfer structure 21; and the first heat transfer structure 11 and the second heat transfer structure 21 always keep in contact; one end of the first elastic component 3 abuts against the first heat sink component 1, and the other end abuts against the second heat sink component 2; the elastic expansion and contraction direction of the first elastic component 3 is along the protruding direction of the first heat transfer structure 11 or the second heat transfer structure 21.

[0101] It can be seen from the above technical solution that during the actual use of the heat sink 01 provided in this specific embodiment, when the heating element is inserted and installed, pressure will be applied to the first heat-conducting surface during the insertion process of the heating element, so that the first heat dissipation component 1 moves in the direction close to the second heat dissipation component 2 along the protruding direction of the first heat transfer structure 11 or the second heat transfer structure 21, and squeezes the first elastic component 3. Under the elastic force of the first elastic component 3, there is a certain contact pressure between the first heat-conducting surface and the heating element, which can realize heat transfer; the heat of the heating element is transferred to the first heat dissipation component 1 through the first heat transfer surface, and because the side surface of the first heat transfer structure 11 is always in contact with the side surface of the second heat transfer structure 21, therefore, the heat is transferred from the first heat dissipation component 1 through the first heat transfer structure 11 to the second heat transfer structure 21 of the second heat dissipation component 2, and the second heat transfer structure 21 transfers the heat to the second heat-conducting surface, and the cooling element contacts the second heat-conducting surface to realize the heat loss of the second heat-conducting surface, thereby cooling the second heat-conducting surface.

[0102] During actual use of the heat sink 01 provided in this specific embodiment, when plugging and unplugging the heating element, the first heat sink component 1 is relatively close to or away from the second heat sink component 2 along the protruding direction of the first heat transfer structure 11 or the second heat transfer structure 21, and the first heat sink component 1 does not affect the second heat sink component 2. The second heat sink component 2 can remain fixed, effectively avoiding the overall ups and downs of the heat sink 01 during the plugging and unplugging of the optical module, thereby avoiding affecting the setting of the cooling element due to the overall ups and downs of the heat sink 01.

[0103] In addition, during actual use of the heat sink 01 provided in this specific embodiment, the first elastic component 3 can maintain a certain contact pressure between the first heat-conducting surface of the first heat-dissipating component 1 and the heating element, which is beneficial to heat transfer and improves heat dissipation efficiency.

[0104] In addition, during actual use of the radiator 01 provided in this specific embodiment, the second heat dissipation component 2 can remain fixed, and the position of the second heat-conducting surface remains unchanged. Multiple radiators 01 can be in contact with the same cooling element, so that the cooling elements in contact with different radiators 01 can be set as an integrated structure, which can effectively reduce the cost of the cooling element.

[0105] In a specific embodiment, the first heat transfer structure 11 includes a plurality of first protrusions 111 disposed at intervals, and the second heat transfer structure 21 includes a plurality of second protrusions 211 disposed at intervals, and the second protrusions 211 are inserted between adjacent first protrusions 111; or, the first protrusions 111 are inserted between adjacent second protrusions 211; a second protrusion 211 is in contact with at least one first protrusion 111 adjacent to it.

[0106] like Figure 5 , Figure 6 As shown, the second heat transfer structure 21 is provided with a plurality of second protrusions 211, such as Figure 7 As shown, the first heat transfer structure 11 is provided with a plurality of first protrusions 111. In actual use, as shown in FIG. Figure 4 As shown, the second convex portion 211 is inserted between adjacent first convex portions 111 , and at least one side surface of the second convex portion 211 is in contact with the adjacent first convex portion 111 .

[0107] Of course, the first protrusion 111 can be configured as follows Figure 7The long strip-shaped protrusions shown in the figure have multiple first protrusions 111 arranged at intervals along the width direction of the first heat transfer structure 11; the first protrusions 111 may also be arranged as multiple discontinuous protrusions arranged at intervals along the length direction of the first heat transfer structure 11, and multiple first protrusions 111 are arranged at intervals along the width direction of the first heat transfer structure 11. When plugged in, the discontinuities of the first protrusions 111 arranged along the length direction of the first heat transfer structure 11 are inserted with second protrusions 211, and the second protrusions 211 are inserted between the adjacent first protrusions 111 along the width direction of the first heat transfer structure 11. The length direction of the first heat transfer structure 11 mentioned in this specific embodiment is Figure 7 The extension direction of the first convex portion 111 in the first heat transfer structure 11 is the direction perpendicular to the length direction in the first heat conducting surface.

[0108] In addition, the second protrusion 211 can be configured as follows Figure 5 , Figure 6 The long strip-shaped protrusions shown in the figure, a plurality of second protrusions 211 are arranged at intervals along the width direction of the second heat transfer structure 21; the second protrusions 211 can also be arranged as a plurality of discontinuous protrusions arranged at intervals along the length direction of the second heat transfer structure 21, and at the same time, a plurality of second protrusions 211 are arranged at intervals along the width direction of the second heat transfer structure 21. When plugged in, the first protrusions 111 are inserted in the discontinuities of the second protrusions 211 arranged along the length direction of the second heat transfer structure 21, and the first protrusions 111 are inserted between the adjacent second protrusions 211 along the width direction of the second heat transfer structure 21. The length direction of the second heat transfer structure 21 mentioned in this specific embodiment is Figure 5 , Figure 6 The extension direction of the second convex portion 211 in the middle, and the width direction of the second heat transfer structure 21 are the directions perpendicular to the length direction in the second heat conducting surface.

[0109] During actual use, the heat of the heating element is transferred to the first heat transfer structure 11 through the first heat transfer surface, and is transferred to the second heat transfer surface of the second heat transfer structure 21 through the first convex portion 111 of the first heat transfer structure 11 and the second convex portion 211 of the second heat transfer structure 21. The cooling element contacts the second heat transfer surface and takes away the heat from the second heat transfer surface.

[0110] In the present specific embodiment, the first heat transfer structure 11 and the second heat transfer structure 21 transfer heat through the contact between the first convex portion 111 and the second convex portion 211. In actual use, since a plurality of first convex portions 111 and second convex portions 211 are provided, the contact area between the first convex portion 111 and the second convex portion 211 can be effectively increased, thereby improving the heat dissipation efficiency. In addition, at least one side surface of the first convex portion 111 is in contact with the second convex portion 211. In the process of the first heat sink and the second heat sink being relatively close to or away from each other, the surface contact between the first convex portion 111 and the second convex portion 211 can play a guiding role, thereby avoiding relative displacement between the first heat sink and the second heat sink.

[0111] In a specific embodiment, the heat sink 01 also includes a second elastic component 4, which is arranged between the adjacent first protrusion 111 and the second protrusion 211, and one side of the second elastic component 4 abuts against the first protrusion 111, and the other side abuts against the second protrusion 211 adjacent to the first protrusion 111, so that the first protrusion 111 and the second protrusion 211 that are in contact with each other have contact pressure.

[0112] The structure of the second elastic component 4 can be set as follows Fig. 9 , Fig.10 The structure shown in the figure, and the spacing between two adjacent first convex portions 111 in the first heat transfer structure 11 is greater than the spacing between other adjacent first convex portions 111; the spacing between two adjacent second convex portions 211 in the second heat transfer structure 21 is greater than the spacing between other adjacent second convex portions 211; in the process of plugging and matching the first convex portion 111 and the second convex portion 211, the second elastic component 4 is arranged between the first convex portion 111 and the second convex portion 211 with a larger spacing, one side of the second elastic component 4 abuts against the side surface of the first convex portion 111, and the other side of the second elastic component 4 abuts against the side surface of the second convex portion 211, so that the contact surface 23 of the first convex portion 111 and the second convex portion 211 has a certain contact pressure, thereby improving the heat transfer effect.

[0113] The second elastic component 4 in this specific embodiment can be configured as follows Fig. 9 , Fig.10 The spring structure shown can also be set to other elastic structures that meet the requirements, which is determined according to actual conditions and will not be described in detail here.

[0114] During actual use of the radiator 01 in this specific embodiment, by providing the second elastic component 4, a certain contact pressure is provided between the first protrusion 111 and the second protrusion 211, which is beneficial to the transfer of heat between the first protrusion 111 and the second protrusion 211, improves the heat transfer efficiency, and further improves the heat dissipation effect.

[0115] On the basis of the above embodiment, the second elastic component 4 can include a first spring sheet 41, a second spring sheet 42 and an adjusting assembly, wherein the first spring sheet 41 abuts against the side of the first protrusion 111; the second spring sheet 42 abuts against the side of the second protrusion 211; the adjusting assembly is used to connect the first spring sheet 41 and the second spring sheet 42, and adjust the distance between the first spring sheet 41 and the second spring sheet 42 to adjust the contact pressure between the first protrusion 111 and the second protrusion 211 that are in contact with each other.

[0116] On the one hand, the radiator 01 may also include a pressure detection component, which is arranged on the side of the first protrusion 111 that contacts the second protrusion 211 or the side of the second protrusion 211 that contacts the first protrusion 111, and is used to detect the contact pressure between the first protrusion 111 and the second protrusion 211.

[0117] The adjustment component can be specifically configured to include a bidirectional screw, a first support plate, and a second support plate, wherein the first support plate is provided with a first threaded hole, the second support plate is provided with a second threaded hole, one end of the bidirectional screw is threadedly connected to the first support plate, the other end of the bidirectional screw is threadedly connected to the second support plate, the first support plate is connected to the first elastic sheet 41, and the second support plate is connected to the second elastic sheet 42. In actual use, by screwing the bidirectional screw, the first support plate and the second support plate can be driven to move relatively close to or away from each other, so that the first elastic sheet 41 and the second elastic sheet 42 are relatively close to or away from each other. In the process of the first elastic sheet 41 and the second elastic sheet 42 moving relatively close to or away from each other, the contact pressure between the side surface of the first protrusion 111 and the side surface of the second protrusion 211 can be adjusted so that the contact pressure between the side surface of the first protrusion 111 and the side surface of the second protrusion 211 meets the requirements.

[0118] In the actual use process of the heat sink 01 provided in this specific embodiment, the contact pressure between the side surface of the first protrusion 111 and the side surface of the second protrusion 211 can be adjusted by adjusting the adjustment component, and the contact pressure between the side surface of the first protrusion 111 and the side surface of the second protrusion 211 can be adjusted according to different use requirements, so that the use range of the heat sink 01 is wider. In addition, in the actual use process, since the contact pressure between the side surface of the first protrusion 111 and the side surface of the second protrusion 211 can be adjusted by the adjustment component, the processing accuracy requirements for the first protrusion 111 and the second protrusion 211 are reduced, which can effectively reduce costs.

[0119] In addition, by providing a pressure detection member, the contact pressure between the first convex portion 111 and the second convex portion 211 can be detected, so that the contact pressure between the first convex portion 111 and the second convex portion 211 can be adjusted more accurately.

[0120] In a specific embodiment, one of the first heat transfer structure 11 and the second heat transfer structure 21 is provided with a limiting protrusion 22, and the other of the first heat transfer structure 11 and the second heat transfer structure 21 is provided with a limiting slide groove 12 for cooperating with the limiting protrusion 22, and the limiting slide groove 12 has an extension along the protruding direction of the first heat transfer structure 11 or the second heat transfer structure 21 to limit the relative distance between the first heat dissipation component 1 and the second heat dissipation component 2.

[0121] Specifically, the limiting protrusion 22 can be arranged on the end surface of the outermost second protrusion 211 facing the first protrusion 111 ; the limiting sliding groove 12 can be arranged on the end surface of the outermost first protrusion 111 facing the second protrusion 211 .

[0122] like Figure 2 , Figure 4 As shown, the number of the second convex parts 211 in the second heat transfer structure 21 is greater than the number of the first convex parts 111 in the first heat transfer structure 11. In the actual plug-in mating process, the first convex parts 111 are inserted between adjacent second convex parts 211, and as shown in FIG. Figure 4 As shown, the second protrusion 211 is located at the outermost side. Figure 5 As shown, a limiting convex portion 22 is provided on the end surface of the outermost second convex portion 211 facing the first convex portion 111, as shown in FIG. Figure 7 As shown, a limiting groove 12 is provided on the end face of the outermost first protrusion 111 facing the outermost second protrusion 211; when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively separated to a maximum distance, the limiting protrusion 22 contacts the side wall of the limiting groove 12, limiting the first heat dissipation component 1 and the second heat dissipation component 2 from further being relatively separated, avoiding the first heat dissipation component 1 and the second heat dissipation component 2 from detaching, and effectively limiting the maximum distance between the first heat dissipation component 1 and the second heat dissipation component 2.

[0123] In this specific embodiment, the limiting protrusion 22 and the limiting slot 12 are provided to limit the relative distance between the first heat dissipation component 1 and the second heat dissipation component 2, and at the same time, prevent the first heat dissipation component 1 from being separated from the second heat dissipation component 2.

[0124] In addition, the limiting protrusion 22 is directly arranged on the second protrusion 211, and the limiting sliding groove 12 is arranged on the side of the first protrusion 111. The structure is reasonably arranged and no additional components are required.

[0125] In a specific embodiment, the first elastic component 3 can be set as a spring sheet, and the number of the first elastic components 3 is two; the first heat dissipation component 1 is provided with a positioning groove 13 for limiting the installation position of the first elastic component 3, the positioning groove 13 is arranged one-to-one with the first elastic component 3, and the two positioning grooves 13 are respectively arranged at both ends of the length direction of the first heat transfer structure 11 in the first heat dissipation component 1; the second heat dissipation component 2 is provided with a contact surface 23 for abutting against the first elastic component 3.

[0126] like Figure 7 As shown, the first heat dissipation component 1 is provided with a positioning groove 13, and the first elastic component 3 is as shown in FIG. Figure 8 As shown, the first elastic component 3 is disposed in the positioning groove 13, and the positioning groove 13 can limit the position of the first elastic component 3 to prevent the first elastic component 3 from moving relative to the first heat dissipation component 1. In addition, as shown in FIG. Figure 5 As shown, the second heat dissipation component 2 is provided with a contact surface 23, the bottom of the first elastic component 3 is located in the positioning groove 13, and the top of the first elastic component 3 abuts against the contact surface 23; in actual use, the second heat dissipation component 2 is generally fixed to the cold plate 7, the position of the first elastic component 3 relative to the first heat dissipation component 1 is fixed, and the first heat dissipation component 1 is fixedly installed, so that the first elastic component 3 can be fixedly set relative to the second heat dissipation component 2.

[0127] The first elastic component 3 may also be configured as other structural forms, which are determined according to actual conditions.

[0128] In this specific embodiment, by providing a positioning groove 13, the installation position of the first elastic component 3 can be fixed, thereby preventing the first elastic component 3 from moving relative to the first heat dissipation component 1 or the second heat dissipation component 2 during use, thereby improving the stability of the first heat dissipation component 1 and the second heat dissipation component 2 in the process of relative approach or distance. In addition, in this specific embodiment, two first elastic components 3 are provided, and the two first elastic components 3 are respectively arranged at both ends of the first heat dissipation component 1, so that the first heat dissipation component 1 and the second heat dissipation component 2 are subjected to uniform force in the process of relative approach or distance.

[0129] In a specific embodiment, at least one of the first protrusion 111 and the second protrusion 211 can be set as an elastic member. When the elastic member is squeezed, the distance between adjacent elastic members increases; when the elastic member is not squeezed, the distance between adjacent elastic members is smaller than the width of the first protrusion 111 or the second protrusion 211 inserted between adjacent elastic members; when the first protrusion 111 and the second protrusion 211 are plugged into each other, the two side surfaces of the first protrusion 111 are respectively in contact with the two adjacent second protrusions 211.

[0130] It should be noted that the elastic member mentioned in this specific embodiment can be set as a spring or a spring, which is determined according to actual conditions and will not be elaborated here.

[0131] In actual use, since the elastic member has a certain elasticity, the two side surfaces of the first protrusion 111 are respectively in contact with the two adjacent second protrusions 211. Compared with the above embodiment, only one side surface of the first protrusion 111 is in contact with the second protrusion 211, which can effectively increase the contact area between the first protrusion 111 and the second protrusion 211, thereby improving the heat transfer efficiency and the heat dissipation effect.

[0132] On the basis of the above embodiment, the elastic member can be an elastic fin 5, in which a bending protrusion 51 is provided; the bending protrusion 51 includes a first bending side wall 511, a second bending side wall 512 and a top end surface connecting the first bending side wall 511 and the second bending side wall 512.

[0133] During actual use, for example, the first protrusion 111 is an elastic fin 5, and the first bent side wall 511 is in contact with a side wall of the adjacent second protrusion 211, and the second bent side wall 512 is in contact with a side wall of the adjacent second protrusion 211. When plugged in, the first bent side wall 511 and the second bent side wall 512 of the bent protrusion 51 are in contact with the second protrusions 211 on both sides respectively, which can effectively increase the contact area between the first protrusion 111 and the second protrusion 211 and improve the heat transfer efficiency. Of course, the second protrusion 211 can also be set as an elastic fin 5, then the first bent side wall 511 is set in contact with a side wall of the adjacent first protrusion 111, and the second bent side wall 512 is set in contact with a side wall of the adjacent first protrusion 111. When plugged in, the first bent side wall 511 and the second bent side wall 512 of the bent protrusion 51 are respectively in contact with the first protrusions 111 on both sides, which can effectively increase the contact area between the first protrusion 111 and the second protrusion 211 and improve the heat transfer efficiency. Of course, the first protrusion 111 and the second protrusion 211 can also be set as elastic fins 5, or part of the multiple first protrusions 111 can be set as elastic fins 5, and part of the multiple second protrusions 211 can be set as elastic fins 5. The specific method is determined according to the actual situation and will not be repeated here.

[0134] It should be noted that the elastic fin 5 can be provided as an integrated structure, such as Fig.15 As shown, it can also be set as a split structure, and each bending protrusion 51 is an independent individual, which is determined according to actual conditions and will not be described in detail here.

[0135] like Fig.15 As shown, the bending protrusions 51 on both sides of the integrated elastic fin 5 are provided with limited curling portions 53, as shown in FIG. Fig.14As shown, when the first heat dissipation component 1 and the second heat dissipation component 2 are plugged in and matched, when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively far away from each other to the maximum distance, the limiting protrusion 22 of the second heat dissipation component 2 contacts the limiting curling portion 53, which can prevent the first heat dissipation component 1 and the second heat dissipation component 2 from separating.

[0136] In this specific embodiment, by setting the first protrusion 111 and / or the second protrusion 211 as an elastic fin 5, the contact area between the first protrusion 111 and the second protrusion 211 can be effectively guaranteed, and the processing difficulty of the first protrusion 111 and / or the second protrusion 211 can be reduced; in addition, the elastic fin 5 can achieve surface-to-surface contact between the first protrusion 111 and the second protrusion 211 by setting the first bent side wall 511 and the second bent side wall 512, and can play a guiding role in the process of the first heat dissipation component 1 and the second heat dissipation component 2 approaching or moving away from each other; in addition, the first protrusion 111 and the second protrusion 211 achieve surface-to-surface contact through the first bent side wall 511 or the second bent side wall 512, which can ensure that the contact area meets the requirements and improve the heat dissipation efficiency.

[0137] Based on the above embodiments, Figure 7 , Figure 11-Figure 14 As shown, the first heat dissipation component 1 can include a first base 15 and an elastic fin 5, and a positioning boss 14 is provided on the side of the first base 15 facing the second heat dissipation component 2, and the first bent side wall 511 and the second bent side wall 512 of the bent protrusion 51 are in contact with the two sides of the positioning boss 14 respectively; the elastic fin 5 is welded to the first base 15.

[0138] The elastic fin 5 can be configured as follows Fig.15 , Fig.16 In the structure shown, during the actual assembly process, the integrated elastic fin 5 is welded to the first base 15, and the integrated elastic fin 5 is easy to install, which can reduce the assembly cost.

[0139] The protruding height of the positioning boss 14 needs to be smaller than the height of the first bent side wall 511 and the second bent side wall 512. The first bent side wall 511 and the second bent side wall 512 are respectively in contact with the two sides of the positioning boss 14, which can effectively increase the contact area between the elastic fin 5 and the first base 15 and improve the heat dissipation efficiency.

[0140] Of course, the elastic fins 5 can also be configured as a split structure, and the split elastic fins 5 correspond to different positioning bosses 14 respectively, and multiple elastic fins 5 need to be installed separately.

[0141] On the other hand, Fig.15As shown, the elastic fin 5 may further include a connecting portion 52 connecting adjacent bent protrusions 51 , and the connecting portion 52 is provided with a third heat conducting surface, and the third heat conducting surface is in close contact with the base between adjacent positioning bosses 14 .

[0142] During actual use, the first heat-conducting surface of the first heat dissipation component 1 contacts the heating element, and the heat of the heating element is transferred to the first base 15 through the first heat-conducting surface. The heat of the first base 15 is transferred to the connecting part 52 through the surface in contact with the connecting part 52, and is transferred to the first bent side wall 511 through the surface in contact with the first bent side wall 511 in the positioning boss 14; the heat is transferred to the second bent side wall 512 through the surface in contact with the second bent side wall 512 in the positioning boss 14, thereby realizing heat transfer; the heat of the elastic fin 5 is transferred to the second heat dissipation component 2 through the second protrusion 211, and the second heat-conducting surface of the second heat dissipation component 2 contacts the cooling element, thereby realizing heat dissipation of the second heat dissipation component 2.

[0143] In this specific embodiment, by providing the first bent side wall 511, the second bent side wall 512 and the connecting portion 52, and providing the positioning boss 14 on the first base 15, the contact area between the first base 15 and the elastic fin 5 can be effectively increased, thereby improving the heat dissipation efficiency. In addition, the elastic fin 5 is provided as an integrated structure, so that the connection between the elastic fin 5 and the first base 15 is more convenient, and the assembly cost is reduced.

[0144] In addition, by providing the connecting portion 52, the contact area between the elastic fin 5 and the first base 15 is increased. In addition to the positioning boss 14, the portion of the first base 15 located between adjacent positioning bosses 14 transfers heat to the connecting portion 52 through the third heat conducting surface. The connecting portion 52 transfers heat to the second protrusion 211, which can further improve the heat transfer efficiency and the heat dissipation effect.

[0145] In a specific embodiment, the first heat dissipation component 1 includes a second base, a first heat transfer structure 11 is arranged on the side of the second base facing the second heat dissipation component 2, and a first heat conduction surface is arranged on the side of the second base facing away from the second heat dissipation component 2; a first elastic heat transfer component that can be elastically retracted along the protruding direction of the first protrusion 111 is arranged between adjacent first protrusions 111, and the first elastic heat transfer component that can be elastically retracted along the protruding direction of the first protrusion 111 is arranged between adjacent first protrusions 111. Fig. 20 , Fig.21 As shown, the first elastic heat transfer component 8 includes a first heat transfer top plate 83, a first elastic support member 81 and a first heat transfer bottom plate 82; the first heat transfer bottom plate 82 is arranged in close contact with the second base, one end of the first elastic support member 81 is connected to the first heat transfer top plate 83, and the other end is connected to the first heat transfer bottom plate 82; the first heat transfer top plate 83 abuts against the end surface of the second protrusion 211 facing the first heat dissipation component 1; the first elastic support member 81 is a heat-conducting metal member.

[0146] Specifically, the first elastic support member 81 in this specific embodiment can be configured as a heat-conducting and elastic structure such as a metal spring or a supporting spring.

[0147] During actual use, when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively far away from or relatively close to each other, the first heat transfer top plate 83 and the end surface of the second protrusion 211 facing the first heat dissipation component 1 are always kept in contact, and the first heat transfer bottom plate 82 and the second base are arranged in a close relationship. The first heat conduction surface transfers the heat of the heating element to the second base, and part of the heat of the second base is transferred to the first heat transfer top plate 83 through the first heat transfer bottom plate 82 and the first elastic support member 81, and is transferred to the second protrusion 211 through the first heat transfer top plate 83. The second protrusion 211 transfers the heat to the second heat conduction surface, and the cooling element dissipates heat from the second heat conduction surface.

[0148] In this specific embodiment, by providing the first elastic heat transfer component 8, the end surface of the second protrusion 211 facing the first heat dissipation component 1 is always in contact with the first heat transfer top plate 83 of the first elastic heat transfer component 8, further increasing the contact surface 23 between the second protrusion 211 and the first heat dissipation component 1, thereby improving the heat transfer efficiency and thus improving the heat dissipation effect. In addition, by providing the first elastic support member 81, the first elastic heat transfer component 8 in this specific embodiment has a certain contact pressure between the second protrusion 211 and the first heat transfer top plate 83, which is beneficial to the transfer of heat and further improves the heat transfer efficiency.

Fig. 20 , Fig.21 As shown, the second elastic heat transfer component 9 includes a second heat transfer top plate 93, a second elastic support member 91 and a second heat transfer bottom plate 92; the second heat transfer bottom plate 92 is arranged in close contact with the third base, one end of the second elastic support member 91 is connected to the second heat transfer top plate 93, and the other end is connected to the second heat transfer bottom plate 92; the second heat transfer top plate 93 is in contact with the end surface of the first protrusion 111 facing the second heat dissipation component 2; the second elastic support member 91 is a heat-conducting metal member.

[0150] Specifically, the second elastic support member 91 in this specific embodiment can be configured as a heat-conducting and elastic structure such as a metal spring or a supporting spring.

[0151] In actual use, when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively far away from or relatively close to each other, the second heat transfer top plate and the end surface of the first convex portion 111 facing the second heat dissipation component 2 are always kept in contact, and the second heat transfer bottom plate and the third base are arranged in a close relationship, the first heat conduction surface transfers the heat of the heating element to the second base, and part of the heat of the second base is transferred to the first heat transfer top plate 83 through the first heat transfer bottom plate 82 and the first elastic support member 81, and is transferred to the second convex portion 211 through the first heat transfer top plate 83, and the second convex portion 211 transfers the heat to the second heat conduction surface; another part of the heat in the second base is transferred to the second heat transfer top plate 93 through the first convex portion 111, and the heat of the second heat transfer top plate 93 is transferred to the third base through the second elastic support member 91 and the second heat transfer bottom plate 92, and the heat of the third base is transferred to the second heat conduction surface; in addition, part of the heat in the second base is transferred to the second heat conduction surface through the first convex portion 111 and the second convex portion 211; the cooling element dissipates heat from the second heat conduction surface.

[0152] In this specific embodiment, by providing a second elastic heat transfer component, the end surface of the first protrusion 111 facing the second heat dissipation component 2 is always in contact with the second heat transfer top plate 93 of the second elastic heat transfer component 9, further increasing the contact surface 23 between the first protrusion 111 and the second heat dissipation component 2, thereby improving the heat transfer efficiency and the heat dissipation effect. In addition, by providing a second elastic support member 91, the second elastic heat transfer component 9 in this specific embodiment has a certain contact pressure between the first protrusion 111 and the second heat transfer top plate, which is beneficial to the transfer of heat and further improves the heat transfer efficiency.

[0154] Specifically, a slide rail extending in a length direction perpendicular to the first protrusion 111 can be set on the fourth base 17 of the first heat dissipation component 1, and the first sliding structure 18 is slidably set along the slide rail. The first locking structure 19 can be set as a locking screw. By screwing the locking screw, the first sliding structure 18 can be locked or unlocked relative to the slide rail.

[0155] During actual use, when adjusting the contact pressure between the first protrusion 111 and the second protrusion 211, the contact pressure between the first protrusion 111 and the second protrusion 211 can be adjusted by adjusting the position of the first heat transfer structure 11; when the first sliding structure 18 drives the first heat transfer structure 11 to slide to a position where the contact pressure between the first protrusion 111 and the second protrusion 211 meets the requirements, the first locking structure 19 is controlled to lock the first sliding structure 18 to the fourth base 17, so that the position of the first sliding structure 18 relative to the fourth base 17 is fixed, thereby achieving the fixation of the first heat transfer structure 11.

[0156] In this specific embodiment, the contact pressure between the first protrusion 111 and the second protrusion 211 can be adjusted by adjusting the sliding position of the first sliding structure 18, which can adapt to different contact pressure requirements between the first protrusion 111 and the second protrusion 211 and adapt to more usage scenarios.

[0157] On the basis of the above embodiments, the first heat dissipation component 1 can also include a fifth base and a first heat transfer structure 11; the second heat dissipation component 2 can include a sixth base and a second heat transfer structure 21; at least one of the first protrusion 111 and the second protrusion 211 includes a first monomer 1111, a second monomer 1112 and a distance adjustment component for adjusting the distance between the first monomer 1111 and the second monomer 1112; the distance adjustment component includes a first movable member 110 connected to the first monomer 1111 and a second movable member 120 connected to the second monomer 1112, and the first movable member 110 and the second movable member 120 can be slidably arranged on the fifth base or the sixth base.

[0158] like Fig.23 As shown, when the first convex portion 111 includes a first monomer 1111, a second monomer 1112, and a distance adjustment component for adjusting the distance between the first monomer 1111 and the second monomer 1112, in actual use, by adjusting the relative positions of the first moving member 110 and the second moving member 120, the distance between the first monomer 1111 and the second monomer 1112 can be adjusted, thereby adjusting the contact pressure between the first monomer 1111 and the adjacent second convex portion 211, the contact pressure between the second monomer 1112 and the adjacent second convex portion 211, and the contact pressure between the second monomer 1112 and the adjacent second convex portion 211. force; when the second protrusion 211 includes a first monomer 1111, a second monomer 1112 and a distance adjusting component for adjusting the distance between the first monomer 1111 and the second monomer 1112, in actual use, by adjusting the relative positions of the first movable member 110 and the second movable member 120, the distance between the first monomer 1111 and the second monomer 1112 can be adjusted, thereby adjusting the contact pressure between the first monomer 1111 and the adjacent first protrusion 111, and the contact pressure between the second monomer 1112 and the adjacent first protrusion 111.

[0159] In this specific embodiment, both side surfaces of the same first protrusion 111 can be in contact with the second protrusion 211, thereby increasing the contact area between the first protrusion 111 and the second protrusion 211, and by setting the first protrusion 111 or the second protrusion 211 as a split structure, the contact pressure of different contact surfaces 23 in the first protrusion 111 and the second protrusion 211 can be adjusted separately, further improving the accuracy of contact pressure adjustment, which is beneficial to improving the heat dissipation effect.

[0160] In a specific embodiment, at least one of the first protrusion 111 and the second protrusion 211 can be set as an elastically retractable structure. Specifically, the first heat transfer structure 11 can include a seventh base and the first protrusion 111, and the second heat transfer structure 21 can include an eighth base and the second protrusion 211; the first protrusion 111 and / or the second protrusion 211 can include a third heat transfer top plate, a retractable side wall and a third heat transfer bottom plate.

[0161] When the first convex portion 111 includes a third heat transfer top plate, a telescopic side wall and a third heat transfer bottom plate, the third heat transfer bottom plate contacts the seventh base, the telescopic side wall is perpendicular to the third heat transfer bottom plate, and the telescopic side wall can be elastically telescoped in a direction perpendicular to the third heat transfer bottom plate, one end of the telescopic side wall is connected to the third heat transfer bottom plate, and the other end is connected to the third heat transfer top plate; an elastic telescopic member is arranged between the third heat transfer bottom plate and the third heat transfer top plate, one end of the elastic telescopic member is connected to the third heat transfer bottom plate, and the other end is connected to the third heat transfer top plate; specifically, the telescopic side wall can be arranged as a threaded tube-shaped telescopic structure, and can also be arranged as a slide plate-shaped structure that can slide relatively to achieve telescope, which is determined according to actual conditions.

[0162] During actual use, the third heat transfer top plate always keeps in contact with the eighth base, the telescopic side wall contacts the outer side wall of the second protrusion 211, and the third heat transfer bottom plate contacts the seventh base; when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively close, the elastic telescopic part is compressed, the telescopic side wall is shortened, and the distance between the third heat transfer bottom plate and the third heat transfer top plate is reduced; when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively far away, the elastic telescopic part elastically stretches, the telescopic side wall stretches, and the distance between the third heat transfer bottom plate and the third heat transfer top plate increases.

[0163] When the second convex portion 211 includes a third heat transfer top plate, a telescopic side wall and a third heat transfer bottom plate, the third heat transfer bottom plate contacts the eighth base, the telescopic side wall is perpendicular to the third heat transfer bottom plate, and the telescopic side wall can be elastically telescoped in a direction perpendicular to the third heat transfer bottom plate, one end of the telescopic side wall is connected to the third heat transfer bottom plate, and the other end is connected to the third heat transfer top plate; an elastic telescopic member is arranged between the third heat transfer bottom plate and the third heat transfer top plate, one end of the elastic telescopic member is connected to the third heat transfer bottom plate, and the other end is connected to the third heat transfer top plate; specifically, the telescopic side wall can be arranged as a threaded tube-shaped telescopic structure, and can also be arranged as a slide-shaped structure that can slide relatively to achieve telescope, which is determined according to actual conditions.

[0164] During actual use, the third heat transfer top plate always keeps in contact with the seventh base, the telescopic side wall contacts the outer side wall of the first protrusion 111, and the third heat transfer bottom plate contacts the eighth base; when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively close, the elastic telescopic part is compressed, the telescopic side wall is shortened, and the distance between the third heat transfer bottom plate and the third heat transfer top plate is reduced; when the first heat dissipation component 1 and the second heat dissipation component 2 are relatively far away, the elastic telescopic part elastically stretches, the telescopic side wall stretches, and the distance between the third heat transfer bottom plate and the third heat transfer top plate increases.

[0165] In this specific embodiment, by setting the first protrusion 111 and / or the second protrusion 211 as an elastically retractable structure, the top end surface of the first protrusion 111 can maintain contact with the eighth base, and / or the top end surface of the second protrusion 211 can maintain contact with the seventh base, thereby effectively increasing the heat transfer area and further improving the heat dissipation effect; in addition, setting the first protrusion 111 and / or the second protrusion 211 as an elastically retractable structure is conducive to resetting the first heat dissipation component 1 when the first heat dissipation component 1 is relatively far away from the second heat dissipation component 2, thereby avoiding the situation where the first elastic component 3 cannot be successfully reset due to insufficient elastic force due to long-term use.

[0166] In addition to the above-mentioned heat sink 01, this specific embodiment further discloses an optical module device, including an optical cage 6, a cold plate 7 and at least one heat sink 01 disclosed in the above-mentioned embodiment; the optical cage 6 is provided with a mounting groove 61 for mounting the optical module and a mounting hole 62 connected to the mounting groove 61; the heat sink 01 is installed at the mounting hole 62, and when the optical module is not installed, at least part of the structure of the heat sink 01 is located in the mounting groove 61; the cold plate 7 is in contact with the second heat conduction surface of the second heat dissipation component 2 in the heat sink 01.

[0167] Specifically, Fig.11 As shown, a chamfer 151 is provided on one side of the first heat-conducting surface of the first heat dissipation component 1 . In actual use, the chamfer 151 is partially located in the mounting groove 61 , which facilitates the optical module to enter the mounting groove 61 when plugging in the optical module.

[0168] In addition, a limiting boss 16 is provided on the outer peripheral edge of the first heat dissipation component 1, and the bottom surface of the limiting boss 16 contacts the surface of the optical cage 6 where the mounting hole 62 is provided; the bottom surface of the limiting boss 16 is higher than the first heat-conducting surface of the first heat dissipation component 1, so that the heat-conducting surface can be located in the mounting groove 61. When the optical module is plugged in, the optical module squeezes the first heat-conducting surface, so that the first heat dissipation component 1 and the second heat dissipation component 2 are relatively close; when the optical module is pulled out, under the elastic force of the first elastic component 3, the first heat-conducting surface of the first heat dissipation component 1 is reset to the position located in the mounting groove 61.

[0169] like Fig.17 , 18 As shown, the optical cage 6 of the optical module device in this specific embodiment is a two-layer structure, such as Fig.17 As shown, the cold plate 7 is arranged on the side of the heat sink 01 away from the mounting hole 62. During the process of plugging in the optical module, since the cold plate 7 does not need to be arranged at the bottom of the mounting groove 61, the cold plate 7 does not interfere with the connector at the rear of the optical module, so the multi-layer optical cage 6 layout plan can be met.

[0170] In the process of plugging and unplugging the optical module, each optical module of the optical module device in this specific embodiment is independently set. When no optical module is inserted in some installation slots 61, the first elastic component 3 in the corresponding heat sink 01 does not deform and is in the original state. When the installation slot 61 of the optical module is inserted, the first elastic component 3 in the heat sink 01 at the corresponding position is compressed, resulting in deformation and elastic force. Since each optical module and the corresponding heat sink 01 are independent of each other, the optical modules are not affected. In addition, in the process of plugging and unplugging the optical module in this specific embodiment, only the position of the first heat sink 1 changes, which will not affect the position of the second heat sink 2. The position of the second heat sink 2 can remain unchanged. Therefore, the cold plates 7 corresponding to the multiple heat sinks 01 can be set as an integrated structure, which is beneficial to reduce processing costs.

[0171] In addition to the above optical module device, the present invention also provides a switch including the optical module device provided by the above embodiment.

[0172] A switch is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch.

[0173] In addition to the above optical module device, the present invention also provides a server including the optical module device provided by the above embodiment.

[0174] On the one hand, the server needs to convert the internal electrical signal into an optical signal through an optical module for high-speed, long-distance transmission in the optical fiber network. The transmission rate of the optical module directly affects the data sending and receiving speed of the server. On the other hand, the optical module is a key device for the server to access the optical fiber network. The network interface card of the server usually reserves an optical module interface. By inserting a suitable optical module, the server can be connected to different network devices, such as switches, routers, etc., thereby building a complex network architecture.

[0175] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0176] The heat sink, optical module device, switch, and server provided by the present invention are described in detail above. The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referred to each other. For the system disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the present invention.
