[0029] See also Figure 1 as well as Figure 2 The embodiment of the present application provides a heat sink 100, which includes a bracket 10, a heat sink 20, a heating element 40 and at least one elastic member 30. The heating element 40 is located between the bracket 10 and the heat sink 20. The elastic member 30 is used to fix the bracket 10 and the heat sink 20 so that the bracket 10, the heat sink 20, the heating element 40 and the elastic member 30 are connected as a whole. The heat generated by the heating element 40 can be quickly transferred out through the heat sink 20.

[0030] The heating element 40 is an element that generates heat during operation, including but not limited to a hard disk, a chip, etc. In this embodiment, the heating element 40 is a hard disk. The heat sink 100 may also include a first thermally conductive film 50 and / or a second thermally conductive film 55. The first thermally conductive film 50 may be located between the heating element 40 and the heat sink 20, and the second thermally conductive film 55 may be located between the heating element 40 and the bracket 10. The first thermally conductive film 50 and the second thermally conductive film 55 are used to bond elements adjacent to the heating element 40, and can also quickly transfer heat.

[0031] The bracket 10 (i.e., the first element) includes a bottom plate 11 and a plurality of side plates 13, the plurality of side plates 13 are arranged around the bottom plate 11 and on the same surface of the bottom plate 11, and the plurality of side plates 13 can be arranged at intervals. The plurality of side plates 13 and the bottom plate 11 form a receiving space, and the heating element 40, the heat sink 20, the first thermally conductive film 50, and the second thermally conductive film 55 are all received in the receiving space. In this embodiment, the bracket 10 includes four side plates 13, and the four side plates 13 are symmetrically arranged on opposite sides of the bottom plate 11. In other embodiments, the number of the side plates 13 is at least two. A first card slot 132 is provided on each side plate 13.

[0032] For ease of explanation, the plane where the bottom plate 11 is located is defined by the X-axis and the Y-axis, the side plate 13 extends along the Z-axis, the X-axis, the Y-axis, and the Z-axis may be perpendicular to each other, and the four side plates 13 are symmetrically arranged on both sides of the bottom plate 11 along the X-axis. In other embodiments, the X-axis, the Y-axis, and the Z-axis are not limited to being perpendicular.

[0033] The first clamping slot 132 penetrates the side plate 13 along the Y axis. Each first clamping slot 132 includes an opening area 1322 and a clamping area 1324. The opening area 1322 and the clamping area 1324 are connected to each other, and the opening area 1322 and the clamping area 1324 generally form an L shape. The opening area 1322 is located on the side of the side plate 13 away from the bottom plate 11, and the clamping area 1324 is located on the side of the opening area 1322 close to the bottom plate 11.

[0034] The side plate 13 further includes a hook portion 134 , which is disposed toward the opening area 1322 and the holding area 1324 , and can separate the opening area 1322 and the holding area 1324 . The hook portion 134 can be used to limit the elastic member 30 .

[0035] The heat sink 20 (i.e., the second element) includes a main body 21 and a plurality of protrusions 23, the number of which is the same as the number of the side plates 13. The main body 21 is roughly parallel to the bottom plate 11, and the protrusions 23 are protruded from the surface of the main body 21 along the Z axis. A portion of each protrusion 23 is spaced apart from the main body 21 to form a second slot 25, and the second slot 25 passes through the heat sink 20 along the Y axis. In other embodiments, the second slot 25 may not pass through the heat sink 20, but may be recessed along the Y axis. The second slot 25 is in the shape of an elongated strip and may be used as a slide groove. The elastic member 30 may be simultaneously received in the first slot 132 and the second slot 25, thereby fixing the heat sink 20 and the bracket 10 together.

[0036] In this embodiment, the protruding portion 23 includes a first blocking section 232, a connecting section 234 and a second blocking section 236. The connecting section 234 connects the first blocking section 232 and the second blocking section 236. The first blocking section 232 and the second blocking section 236 are arranged at both ends of the connecting section 234 along the X axis. The first blocking section 232 and the second blocking section 236 are both connected to the main body 21, and the connecting section 234 is arranged at a distance from the main body 21, thereby forming a second slot 25. The first blocking section 232 is arranged inwardly relative to the second blocking section 236.

[0037] The surface of the main body 21 where the protruding portion 23 is provided is also provided with a plurality of heat dissipation portions 27 , and the heat dissipation portions 27 are used to quickly dissipate heat.

[0038] See also Figure 3 The elastic member 30 can be an integrated structure and can be deformed. On the one hand, it is easy to install. On the other hand, the elastic member 30 can be deformed after being installed in the radiator 100 to fix the heat sink 20 and the bracket 10, and can also provide error space for the components of the radiator 100.

[0039] Each elastic member 30 may include a handle portion 31, two crank portions 33, two connecting portions 35, two plug-in portions 37 and two crimping portions 39. The two crank portions 33 are located at both ends of the handle portion 31. Each connecting portion 35 connects a crank portion 33 and a plug-in portion 37. The crimping portion 39 connects the plug-in portion 37 and extends toward the handle portion 31.

[0040] The handle portion 31 protrudes relative to the crank portion 33 to form a space. The handle portion 31 is roughly C-shaped and is used for users to hold. After the elastic member 30 is assembled in the radiator 100, the handle portion 31 is located between the two side panels 13. The handle portion 31 is spaced apart from the heat sink 20 to facilitate the disassembly and assembly of the elastic member 30.

[0041] The two crank portions 33 are located at two ends of the handle portion 31 and expand outwardly. Each crank portion 33 is used to penetrate a first slot 132 along the Y-axis to be clamped in the first slot 132 .

[0042] Each connecting portion 35 is substantially perpendicular to the crank portion 33 , and each connecting portion 35 is located on a side of the side plate 13 facing away from the heat dissipation plate 20 .

[0043] The plug-in portion 37 and the crank portion 33 connected to the same connecting portion 35 both protrude inwardly relative to the connecting portion 35, and the plug-in portion 37 is used to be received in the second slot 25. That is, each elastic member 30 can be clamped in the two first slots 132 and the two second slots 25. Each plug-in portion 37 is bent, for example, each plug-in portion 37 is roughly U-shaped or V-shaped, so that the plug-in portion 37 can be deformed. When the crank portion 33 is clamped in the first slot 132 and the plug-in portion 37 is received in the second slot 25, the plug-in portion 37 can be pressed against the protruding portion 23, the plug-in portion 37 is in a compressed state, and the two elastic members 30 are in a state of confrontation and tension along the X-axis, so that the bracket 10 and the heat sink 20 are fixed along the X-axis.

[0044] The plug-in portion 37 connects the connecting portion 35 and the crimping portion 39, and the crimping portion 39 extends toward the crank portion 33. The crimping portion 39 is deformed relative to the connecting portion 35 so as to be pressed on the surface of the main body 21. The crank portion 33 and the plug-in portion 37 on the same side of the handle portion 31 can limit the bracket 10 and the heat sink 20 along the X-axis; the crank portion 33 and the plug-in portion 37 on both sides of the handle portion 31 can limit the bracket 10 and the heat sink 20 along the Y-axis; the elastic action between the crimping portion 39 and the connecting portion 35 can limit the bracket 10 and the heat sink 20 along the Z-axis, thereby fixing the bracket 10 and the heat sink 20.

[0045] See also Figure 4Before the elastic member 30 is assembled in the heat sink 100, there is a first angle θ1 between the connecting portion 35 and the crimping portion 39; after the elastic member 30 is assembled in the heat sink 100, there is a second angle θ2 between the connecting portion 35 and the crimping portion 39; the first angle θ1 is greater than the second angle θ2. After the elastic member 30 is assembled in the heat sink 100, the side plate 13 can be located between the crimping portion 39 and the connecting portion 35, and the crimping portion 39 abuts against the main body 21 to limit the bracket 10 and the heat sink 20 along the Z axis. The length of the crimping portion 39 and the size of the first angle θ1 between the crimping portion 39 and the connecting portion 35 can affect the force of the elastic member 30 to fix the bracket 10 and the heat sink 20 along the Z axis.

[0046] When the elastic member 30 is assembled in the heat sink 100, the end of the crimping portion 39 that is away from the plug-in portion 37 is tilted toward the direction away from the main body portion 21, so that when the elastic member 30 is installed, the crimping portion 39 is in arc contact with the heat sink 20, reducing the friction resistance during relative sliding and preventing scratches on the heat sink 20.

[0047] See also Figure 5 , Figure 6 as well as Figure 7 In order to more clearly illustrate the connection relationship between the various components of this embodiment, the installation process of the heat sink 100 provided in this embodiment is described in detail below.

[0048] See also Figure 5 , attach the first thermally conductive adhesive sheet 50 to the surface of the heat sink 20. The first thermally conductive adhesive sheet 50 is attached to the surface of the main body 21 away from the heat sink 27. The two connecting portions 35 of the elastic member 30 are opened relative to the handle portion 31, and the two plug-in portions 37 are respectively inserted into the second slots 25 of the heat sink 20 to obtain the first assembly 60.

[0049] See also Figure 6 , attach the second thermally conductive film 55 to the surface of the bracket 10. The second thermally conductive film 55 is attached to the surface of the bottom plate 11 provided with the side plate 13. The heating element 40 is arranged in the bracket 10 and bonded to the second thermally conductive film 55, and the second assembly 70 is obtained.

[0050] See also Figure 7, assemble the first component 60 and the second component 70. The first component 60 is placed on the side of the second component 70 where the heating element 40 is provided, the elastic member 30 is located on the side of the heat sink 20 away from the second component 70, the side plate 13 is located between the connecting portion 35 and the crimping portion 39, the crimping portion 39 is placed on the surface of the main body 21, and the connecting portion 35 and the handle portion 31 are tilted relative to the main body 21. The plug-in portion 37 is pre-held against the second blocking section 236, and the handle portion 31 is pressed down along the Z axis toward the main body 21, and the crank portion 33 passes through the opening area 1322 of the first clamping groove 132 and moves along the X axis to the clamping area 1324, driving the elastic member 30 to move along the X axis as a whole, and the plug-in portion 37 can move toward the first blocking section 232 in the second clamping groove 25. During the movement, the crimping portion 39 always abuts against the surface of the main body 21 and slides on the surface of the main body 21. When the force acting on the elastic member 30 is released, the crank portion 33 moves along the Z axis under the action of its own elastic force and abuts against the side plate 13 , and the hook portion 134 can limit the crank portion 33 from moving along the X axis.

[0051] The radiator 100 provided in the embodiment of the present application has a simple assembly process and can fix multiple components together without a riveting process; the interaction between the elastic member 30, the bracket 10 and the heat sink 20 can be limited in multiple directions, so that the bracket 10, the heat sink 20, the heating element 40 and the elastic member 30 can be connected into a tight whole; the second slot 25 on the heat sink 20 reserves a movable space for the elastic member 30 to move along the Z axis, and the elastic member 30 can move along the Z axis under the action of its own elasticity; the crank portion 33 and the plug-in portion 37 located on both sides of the handle portion 31 can limit the bracket 10 and the heat sink 20 along the Y axis; when the heating element 40 moves along the X axis under the action of an external force, the plug-in portion 37 can slide in the second slot 25 relative to the heat sink 20, and the heat sink 20 can move synchronously along the X axis relative to the heating element 40, so that the bracket 10 and the heat sink 20 can still be tightly connected with the heating element 40, thereby effectively ensuring the structural stability and heat dissipation performance of the radiator 100 during installation, transportation and working conditions.
