Description

Technical Field

[0001] The utility model relates to the field of heat sinks, in particular to a riveted integrated heat sink structure. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the form of plates, sheets, or multiple sheets. For example, a computer's CPU central processing unit requires a fairly large heat sink, as do the power tubes and line tubes in televisions, and the power amplifier tubes in amplifiers.

[0003] The installation fit between the heat sink and the main body is one of the key factors for heat conduction efficiency. However, a heat sink of a special shape mainly adopts a side-insertion structure to achieve the installation of multiple heat sinks. The fixing method is generally glue bonding, so the installation is more troublesome. In addition, there is a thermal conductivity difference between the heat sink and the main body, which affects the heat dissipation effect.

[0004] Therefore, in order to ensure the heat dissipation effect, a structure such as Chinese patent CN202321585416.5 is generally adopted to increase the heat dissipation area; of course, there is also an integrated molding structure to improve the heat dissipation effect, but the one-piece molding structure is generally processed by CNC, so its production cost is relatively high. Utility Model Content

[0005] The main purpose of the utility model is to propose a riveted radiator structure, which aims to improve the structure of the heat sink, make the sheet body and the frame body more tightly combined by riveting, and at the same time improve the heat dissipation effect, and compared with the one-piece molded structure, the production cost is lower.

[0006] To achieve the above purpose, the utility model provides a riveted radiator structure, comprising:

[0007] A frame body, wherein support parts are extended downwardly on both sides of the frame body, and the wall surfaces opposite to the two support parts are respectively provided with a plurality of sets of parallel positioning grooves;

[0008] The heat sink body has a width greater than a predetermined width of the positioning groove, and the position where the heat sink body extends into the positioning groove is a wing portion,

[0009] The side wing portion and / or the positioning groove is provided with a deformation portion,

[0010] When the heat sink body is riveted into the positioning groove, the deformation portion is deformed by force and is fixedly attached to the side wing portion of the heat sink body;

[0011] A plurality of heat sink bodies are arranged at intervals.

[0012] In the actual design, the installation of the heat sink is facilitated by the parallel arrangement of the positioning grooves. Specifically, when the heat sink is inserted into the positioning groove, the pressing device drives the heat sink to be riveted into the positioning groove. At the same time, the deformation portion is deformed by the pressure and riveted with the side wings of the heat sink, thereby achieving the installation of multiple heat sinks arranged at intervals on the frame body, effectively improving the problem of the existing radiator structure being affected by the gap in the heat dissipation effect, and multiple heat sinks arranged in parallel effectively improve the heat dissipation effect of the heating element.

[0022] like Figures 1 to 4 As shown, a riveted heat sink structure includes:

[0023] A frame body 1, wherein support portions 11 are extended downwardly from both sides of the frame body 1, and the wall surfaces opposite to the two support portions 11 are respectively provided with a plurality of sets of parallel positioning grooves 12;

[0024] The heat sink body 2 has a width greater than the predetermined width of the positioning groove 12, and the position where the heat sink body 2 extends into the positioning groove 12 is the side wing portion 21.

[0025] The side wing portion 21 and / or the positioning groove 12 is provided with a deformation portion 3.

[0026] When the heat sink body 2 is riveted into the positioning groove 12, the deformation portion 3 is deformed by force and is fixedly attached to the side wing portion 21 of the heat sink body 2;

[0027] A plurality of heat sink bodies 2 are arranged at intervals.

[0028] In the actual design, the installation of the heat sink 2 is facilitated by the parallel arrangement of the positioning grooves 12. Specifically, when the heat sink 2 is inserted into the positioning grooves 12, the heat sink 2 is riveted into the positioning grooves 12 by the driving of the pressing device. At the same time, the deformation portion 3 is deformed by pressure and riveted with the side wings of the heat sink 2, thereby achieving the installation of multiple heat sinks 2 arranged at intervals on the frame body 1, effectively improving the problem of the existing radiator structure being affected by the gap in the heat dissipation effect, and multiple heat sinks 2 arranged in parallel effectively improve the heat dissipation effect of the heating element.

[0029] Specifically, the deformation part 3 is integrally formed with the frame body 1. For example, the frame body 1 is made of aluminum alloy material and is formed by CNC processing or extrusion, so the structure of the heat sink body 2 is simpler to install.

[0030] In the embodiment of the utility model, the deformation part 3 is arranged on the outer peripheral wall of the side wing part 21 or the inner peripheral wall of the deformation part 3 having the positioning groove 12. Through the structure of the width difference, when passing through the riveting device, the deformation part 3 is squeezed and deformed by pressure, thereby realizing the structure of the heat sink body 2 and the frame body 1 being riveted as a whole.

[0031] Of course, the cross section of the side wing portion 21 may also be a trapezoidal shape along the length direction or the width direction, thereby achieving the function of special-shaped snap fit and the corresponding riveting effect.

[0032] Specifically, the lower wall of the frame body 1 is provided with first heat dissipation ridges 41 arranged at intervals.

[0033] In the embodiment of the utility model, the heat sink body 2 is provided with second heat dissipation ridges at intervals along its length direction. The first heat dissipation ridges 41 and the second heat dissipation ridges 42 are provided to increase the heat dissipation area of ​​the heat sink structure, wherein the fluid flows along the length direction of the frame body 1, and the heat can be contacted with the air faster, thereby improving the heat dissipation effect.

[0034] Specifically, the deformation part 3 is made of aluminum alloy material, and the frame body 1 and the heat sink body 2 are made of copper material. This improves the overall heat dissipation effect; of course, the frame body 1 can also be supported by aluminum alloy, or the heat sink body can be supported by aluminum alloy, wherein the ductility of aluminum alloy is good, so that after the frame body 1 and the heat sink body 2 are riveted together, there will be no large deformation error in the appearance.

[0035] In the embodiment of the utility model, the frame body is provided with a flow hole 5 penetrating along its length direction. (The heat dissipation area of ​​the radiator is further increased. Of course, when there is a fan structure, the heat of the radiator can be diffused into the environment more quickly, thereby improving the heat dissipation effect.)

[0036] Specifically, the frame body has a plurality of legs 6 extending downward, and the legs are provided with screw holes 61, thereby facilitating the installation of the heat sink, wherein the heat sink is mainly used for passive heat dissipation of some electronic components, such as capacitors and other products.

[0037] In the embodiment of the utility model, the side wall of the frame body is provided with a positioning hole 7. According to the different shapes of the product, the heating element can also be attached to the frame body 1 through the positioning hole, thereby achieving lateral heat dissipation.

[0038] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
