Description

Technical Field

[0001] The present invention relates to the field of heat dissipation device technology, and in particular to a heat sink module. Background Technology

[0002] Heat sinks for control devices such as computer mainframes and control cabinets are typically mounted and secured to the heat-generating element using fasteners. One existing type of heat sink fastener usually uses a one-piece stamped retaining ring, which is connected and secured to the heat sink using a snap-fit ​​method. However, one-piece stamped retaining rings occupy a large amount of space and are easily deformed during production and transportation, rendering them unusable. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide a heat sink module that occupies less space and is easier to transport.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a heat sink module, including a heat sink and a fastener for fixing the heat sink to a corresponding heating element. The outer surfaces of the side walls on opposite sides of the heat sink are symmetrically provided with slots. The fastener is formed by two fastener pieces in a semi-enclosed structure. Each fastener piece includes a main body, a free arm that bends and extends from opposite ends of the main body toward the same side of the main body, and a pressure foot that protrudes outward from the main body or the free arm and is used to fix it to a carrier plate that carries the heating element. The ends of the two free arms of each fastener piece are respectively provided with elastic snap-fit ​​portions. The free arms of different fastener pieces are inserted into the slots from different ends of the slots on opposite sides of the heat sink and elastically press against the lower side wall of the slot. The elastic snap-fit ​​portions at the ends of the free arms of the two fastener pieces located in the slots on the same side are paired and snap-fitted together.

[0005] Furthermore, the elastic snap-fit ​​portions at the ends of the free arms of the two fasteners are offset from each other in the width direction of the free arms.

[0006] Furthermore, the thickness of the fastener is adapted to the width of the slot, and the upper and lower sidewalls of the slot abut against the upper and lower surfaces of the fastener to position the fastener in the thickness direction.

[0007] Furthermore, the elastic locking parts at the ends of the two free arms of one of the fasteners are symmetrically arranged slots, and the elastic locking parts at the ends of the two free arms of the other fastener are barbs. The two fasteners are fixed by the corresponding hooks and hooks engaging with each other through the slots. The corresponding hook part of the barb that engages with the slot is an arc-shaped protrusion.

[0008] Furthermore, the elastic locking parts at the ends of the two free arms of each fastener are respectively a slot and a barb. Each fastener is fixed by hooking the barb into the slot of another fastener. The hook of the barb that is inserted into the slot is an arc-shaped protrusion.

[0009] Furthermore, the outer surface of the sidewalls at opposite ends of the heat sink is also formed with an end groove between the two slots and with both ends connected to the corresponding ends of the two slots, and the main body is inserted into the end groove.

[0010] Furthermore, the slot and the end groove are respectively provided with positioning protrusions that protrude from the bottom wall of the groove towards the opening of the groove, and the inner edge of the fastener is correspondingly recessed to form a positioning groove. When the fastener is inserted into the slot, the positioning protrusions and positioning grooves cooperate to position the fastener in the slot.

[0011] Furthermore, the positioning protrusion in the slot is disposed at the position where the two fasteners engage with each other. At the fastener engagement position in each slot, the elastic engaging portion of one fastener is adjacent to the positioning protrusion, while the elastic engaging portion of the other fastener is adjacent to the slot opening. The inner edge of the elastic engaging portion adjacent to the positioning protrusion is correspondingly recessed to form the positioning groove.

[0012] Furthermore, the presser foot extends outward from the junction of the main body and the free arm, and the presser foot is provided with a strip-shaped hole for the fastener to pass through.

[0013] Furthermore, the fastener also has reinforcing ribs at the joints of the main body, free arm, and presser foot.

[0014] After adopting the above technical solution, the embodiments of the present invention have at least the following beneficial effects: The embodiments of the present invention symmetrically provide slots on the outer surfaces of the side walls on opposite sides of the radiator, and the fastener is formed by two fastening pieces in a semi-enclosed structure. This results in a smaller volume and easier transportation. Moreover, during specific assembly, the free arms of the two fastening pieces are inserted into the slots from different ends of the slots on opposite sides of the radiator, so that the free arms of the fastening pieces elastically press against the lower side wall of the slot. Furthermore, the connection and positioning of the free arms of the two fastening pieces can be achieved by matching and engaging the elastic snap-fit ​​parts at the ends of the free arms of the two fastening pieces in the slot on the same side. This makes assembly and disassembly very convenient. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. Moreover, the embodiments and features in the embodiments of the present application can be combined with each other unless otherwise specified.

[0021] like Figures 1-5 As shown, an optional embodiment of the present invention provides a heat sink module, including a heat sink 1 and a fastener 3 for fixing the heat sink 1 to a corresponding heat-generating element. The outer surfaces of the sidewalls on opposite sides of the heat sink 1 are symmetrically provided with slots 10. The fastener 3 is formed by two fastener pieces 30 in a semi-enclosed structure. Each fastener piece 30 includes a main body 301, a free arm 303 extending from opposite ends of the main body 301 toward the same side of the main body 301, and a fastener extending from the main body 301 or the free arm 303. The pressure foot 305 protrudes outward and is used to fix it to the carrier plate that carries the heating element. Each of the two free arms 303 of each fastener 30 is provided with an elastic snap-fit ​​part 307 at its end. The free arms 303 of different fasteners 30 are inserted into the slot 10 from different ends of the slot 10 on opposite sides of the heat sink 1 and elastically press against the slot side wall of the slot 10 located on the lower side. The elastic snap-fit ​​parts 307 at the ends of the free arms 303 of two fasteners 30 located in the slot 10 on the same side are paired and snap-fitted together.

[0022] In this embodiment of the invention, slots 10 are symmetrically provided on the outer surfaces of the side walls on opposite sides of the radiator 1, and the fastener 3 is formed by two fastening pieces 30 in a semi-enclosed structure. This results in a smaller volume and easier transportation. During assembly, the free arms 303 of the two fastening pieces 30 are inserted into the slots 10 from different ends on opposite sides of the radiator 1, so that the free arms 303 of the fastening pieces 30 elastically press against the lower side wall of the slot 10. The elastic locking parts 307 at the ends of the free arms 303 of the two fastening pieces 30 in the slot 10 on the same side are matched and locked together to achieve the connection and positioning of the free arms 303 of the two fastening pieces 30. The assembly and disassembly are very convenient.

[0023] In an optional embodiment of the present invention, such as Figures 3-5 As shown, the elastic engaging portions 307 at the ends of the free arms 303 of the two fasteners 30 are staggered relative to each other in the width direction of the free arms 303. In this embodiment, the elastic engaging portions 307 at the ends of the free arms 303 of the two fasteners 30 are staggered relative to each other in the width direction of the free arms 303. When the two fasteners 30 are connected, the free arms 303 of the two fasteners 30 can laterally cover the engaging portion of the elastic engaging portion 307, thereby protecting the engaging portion.

[0024] In another optional embodiment of the invention, such as Figure 5 As shown, the thickness of the fastener 30 is adapted to the groove width of the slot 10, and the upper and lower sidewalls of the slot 10 abut against the upper and lower surfaces of the fastener 30 respectively, thereby positioning the fastener 30 in the thickness direction. In this embodiment, by setting the thickness of the fastener 30 to be adapted to the groove width of the slot 10, the slot 10 is used to achieve positioning of the fastener 30 in the thickness direction.

[0025] In another optional embodiment of the invention, such as Figure 3 As shown, the elastic engaging portions 307 at the ends of the two free arms 303 of one fastener 30 are symmetrically arranged slots, while the elastic engaging portions 307 at the ends of the two free arms 303 of the other fastener 30 are barbs. The two fasteners 30 are fixed by the corresponding hook-and-loop engagement of the slots and barbs. The corresponding hook portion 307a of the barb that engages in the slot is an arc-shaped protrusion. In this embodiment, the two free arms 303 of one fastener 30 are provided with slots, and the two free arms 303 of the other fastener 30 are provided with barbs. By utilizing the corresponding hook-and-loop engagement of the slots and barbs, the engaging and positioning of the free arms 303 of the two fasteners 30 can be effectively achieved. Moreover, the arc-shaped protrusion of the corresponding hook portion 307a that engages in the slot facilitates the movement of the hook portion 307a into and out of the slot, making assembly easier. Furthermore, the fasteners 30 have the same structure, which facilitates manufacturing.

[0026] In another optional embodiment of the invention, such as Figure 4 As shown, the elastic engaging portions 307 at the ends of the two free arms 303 of each fastener 30 are respectively a slot and a barb. Each fastener 30 is fixed by hooking the barb into the slot of the other fastener 30. The hook portion of the barb that engages in the slot is an arc-shaped protrusion. In this embodiment, both free arms 303 of the two fasteners 30 are provided with slots and barbs. Similarly, by using the slot and the barb to engage, the engaging and positioning of the free arms 303 of the two fasteners 30 can be effectively achieved. Moreover, the hook portion 307a of the barb that engages in the slot is an arc-shaped protrusion, which facilitates the movement of the hook portion 307a into and out of the slot, making assembly easier.

[0027] In yet another optional embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the outer surfaces of the sidewalls at opposite ends of the radiator 1 are also formed with end grooves 12, which are located between the two slots 10 and are respectively connected to the corresponding ends of the two slots 10. The main body 30 is inserted into the end grooves 12. In this embodiment, the outer surfaces of the sidewalls at opposite ends of the radiator 1 are also formed with end grooves 12. When assembling the fastener 3, the inner edges of the main bodies 30 of the two fastener pieces 30 are inserted and positioned in the end grooves 12, which can further enhance the connection and positioning effect between the two fastener pieces 30 and the radiator 1.

[0028] In an optional embodiment of the present invention, such as Figure 1 , Figure 3 As shown, the slot 10 and the end groove 12 are respectively provided with positioning protrusions 14 protruding from the bottom wall of the groove towards the opening of the groove. The inner edge of the fastener 30 is correspondingly recessed to form a positioning groove 308. When the fastener 30 is inserted into the slot 10, the positioning protrusions 14 and the positioning grooves 308 cooperate to position the fastener 30 in the slot 10. In this embodiment, the positioning grooves 308 on the fastener 30 are also assembled and cooperated with the positioning protrusions 14 in the slot 10 and the end groove 12 to achieve accurate insertion of the fastener 30 into the corresponding positions of the slot 10 and the end groove 12, further improving the positioning effect.

[0029] In yet another optional embodiment of the present invention, such as Figure 1 and Figure 3As shown, the positioning protrusion 14 within the slot 10 is positioned where the two latching pieces 30 engage with each other. At each latching point of the latching pieces 30 within the slot 10, the elastic latching portion 307 of one latching piece 30 is adjacent to the positioning protrusion 14, while the elastic latching portion 307 of the other latching piece 30 is adjacent to the groove of the slot 10. The inner edge of the elastic latching portion 307 adjacent to the positioning protrusion 14 is correspondingly recessed to form the positioning groove 308. In this embodiment, by adopting the above-described configuration, a positioning groove 308 is formed at the latching point of two adjacent latching pieces 30. The effective positioning of the latching points of the two latching pieces 30 within the slot 10 is enhanced by the assembly and cooperation between the positioning groove 308 and the positioning protrusion 14.

[0030] In another optional embodiment of the invention, such as Figure 1 As shown, the pressure foot 305 extends outward from the connection point between the main body 301 and the free arm 303, and the pressure foot 305 has a strip-shaped hole 305a for the fastener to pass through. In this embodiment, by placing the pressure foot 305 at the connection point between the main body 301 and the free arm 303, the three are interconnected, which can effectively improve the connection strength of the three, and by providing a strip-shaped hole 305a on the pressure foot 305, it is convenient for the fastener to pass through and be fixed to the carrier plate of the heating element.

[0031] In another optional embodiment of the invention, such as Figure 1 As shown, the fastener 30 also has reinforcing ribs 309 formed at the joints of the main body 301, free arm 303, and presser foot 305. In this embodiment, by forming reinforcing ribs 309 at the joints of the main body 301, free arm 303, and presser foot 305, the mechanical strength of the fastener 30 extending from the presser foot 305 can be effectively enhanced, preventing the presser foot 305 from breaking due to insufficient strength.

[0032] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present invention.
