Description

Technical Field

[0001] The utility model relates to the field of heat sinks, in particular to an inter-riveted heat sink. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It's typically made of aluminum alloy, brass, or bronze in the form of plates, sheets, or multiple sheets. For example, the CPU in a computer requires a fairly large heat sink, as do the power and line transistors in a television, and the power amplifier tubes in an amplifier. Heat sinks are typically coated with a layer of thermal grease on the contact surface between the electronic component and the heat sink. This allows the heat generated by the component to be more efficiently transferred to the heat sink, where it is then dissipated into the surrounding air.

[0003] The existing heat sink also has the following defects:

[0004] 1) Different areas of heat sinks are required for electronic components of different devices (such as the computer CPU and power tube mentioned above). When the heat dissipation effect needs to be enhanced, a heat sink with a larger area needs to be replaced. The heat sink is usually a whole structure, which is installed on the circuit board with fasteners such as screws, and then contacts the electronic components through the heat sink to transfer heat and achieve the heat dissipation effect. Therefore, the heat sinks required by the electronic components of different devices are of different lengths and areas. The whole heat sink cannot be spliced together, and heat sinks of multiple sizes are required to meet the needs of electronic components of different devices. This is very troublesome and inconvenient to assemble multiple heat sinks to increase their heat dissipation area. It is also inconvenient to splice multiple heat sinks to meet the needs of electronic components of different devices.

[0005] 2) During the long-term use of the heat sink, dust and other impurities will accumulate between the heat sinks, resulting in reduced heat dissipation effect. If the heat cannot be dissipated, it will cause damage to the electronic components. Therefore, in order to ensure the heat dissipation effect of the heat sink, it is necessary to regularly clean the dust accumulated on the heat sink. Since the space between two adjacent heat sinks is narrow and the heat sinks are fixed with fasteners such as screws, it is not convenient to remove the heat sink, which will make the cleaning of impurity pollution time-consuming and labor-intensive, and will cause damage to the heat sink. It is inconvenient to remove the heat sink to remove dust and it is inconvenient to clean. Utility Model Content

[0006] In order to overcome the deficiencies of the existing technical solutions, the utility model provides an inter-riveted heat sink, which can effectively solve the technical problems that the existing heat sink is inconvenient to assemble, and it is inconvenient to disassemble the heat sink to remove dust and clean.

[0007] The technical solution adopted by the utility model to solve its technical problem is: an inter-riveted heat sink, comprising a fixed plate and a heat plate, the side surfaces of the fixed plate extending outward to form a snap strip, the snap strip extending along the fixed plate, the two sides of the heat plate are recessed to form a snap groove that is mutually adapted to the snap strip, the length of the snap strip is the same as the length of the snap groove, the top surface of the heat plate is provided with a plurality of limiting grooves, the plurality of limiting grooves all extend along the heat plate, the plurality of limiting grooves are equidistantly arranged, the interior of the limiting groove is provided with a slidable fin, the length of the fin is the same as the length of the limiting groove, the bottom of the fin extends outward to form a limiting portion, and the limiting portion is slidably connected to the limiting groove.

[0008] Furthermore, corresponding screw holes are provided on the surfaces of the fixing plate and the heat dissipation plate, long screws are provided on the surfaces of the fixing plate and the heat dissipation plate, and the heat dissipation plate is threadedly connected to the fixing plate via the long screws.

[0009] Furthermore, the fixing plate, the heat dissipation plate and the fins are all made of aluminum-copper alloy.

[0010] Furthermore, two heat dissipation plates are provided, and the two heat dissipation plates are symmetrically distributed around the center line of the fixing plate.

[0011] Furthermore, the fixing plate is in a cross shape and is made of metal.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1) The utility model is a riveted heat sink, in which the snap-fit strips formed by extending from the side of the fixing plate and the recessed slots on both sides of the heat sink are adapted to each other, thereby achieving a stable connection between the heat sink and the fixing plate, and multiple heat sinks can be spliced together to meet the needs of different electronic components.

[0014] 2) The utility model provides an inter-riveted heat sink. When the dust on the fin needs to be cleaned, the fin can be pulled outward to slide out of the limit groove, so that the fin is out of the limit groove, thereby facilitating the removal of the fin and cleaning the dust on its surface, greatly improving the effect of cleaning the dust on the fin.

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 4 The fins 3 are provided with a plurality of grooves 5 on the top of the heat sink 1, and the grooves 5 are arranged at equal intervals to form a plurality of grooves 6 on the bottom of the heat sink 1. The grooves 5 are provided with a plurality of grooves 6 on the top of the heat sink 1, and the grooves 5 are arranged at equal intervals to form a plurality of grooves 6 on the bottom of the heat sink 1. The grooves 5 are provided with a plurality of grooves 5 on the top of the heat sink 1, and the grooves 5 are provided with a plurality of grooves 6 on the bottom of the heat sink 1. The grooves 5 are provided with a plurality of grooves 5 on the top of the heat sink 1, and the grooves 5 are provided with a plurality of grooves 6 on the bottom of the heat sink 1. The fins 3 are connected by threads, and corresponding screw holes 7 are set on the surfaces of the fixing plate 2 and the heat dissipation plate 1, and are threadedly connected by long screws 8, which further enhances the structural stability of the heat sink, especially in a vibration environment, and can effectively prevent the heat dissipation plate 1 from loosening or falling off. The fixing plate 2, the heat dissipation plate 1 and the fins 3 are all made of aluminum-copper alloy. The aluminum-copper alloy is used as the material of the fixing plate 2, the heat dissipation plate 1 and the fins 3, which fully utilizes the light weight and high thermal conductivity of aluminum and the excellent electrical conductivity of copper, so that the heat sink not only has good heat dissipation performance, but also has high strength and corrosion resistance, while reducing the overall weight, which is beneficial to energy saving and cost reduction. The heat dissipation plate 1 is provided with two pieces, and the two heat dissipation plates 1 are symmetrically distributed about the center line of the fixing plate 2. The fixing plate 2 is in a cross shape. The fixing plate 2 is made of metal material. The fixing plate 2 adopts a cross-shaped design, which not only enhances its structural strength, but also better supports and fixes the heat dissipation plate 1.

[0023] The present embodiment is an inter-riveted heat sink, in which the snap-fit strips 6 formed by extending from the side of the fixed plate 2 and the recessed slots 9 on both sides of the heat sink 1 are adapted to each other, thereby achieving a stable connection between the heat sink 1 and the fixed plate 2, and multiple heat sinks can be spliced together to meet the needs of different electronic components. When it is necessary to clean the dust on the fins 3, the fins 3 can be pulled outward to slide out of the limiting slots 5, so that the fins 3 are out of the limiting slots 5, thereby facilitating the disassembly of the fins 3 and cleaning the dust on their surfaces, thereby greatly improving the effect of cleaning the dust on the fins 3.

[0024] When in use, align the card slot 9 of the heat sink 1 with the card slot 6 of the fixed plate 2, connect the heat sink 1 with the fixed plate 2 by sliding it, and pass the long screw 8 through the screw to fix the heat sink 1 and the fixed plate 2 together. By increasing the number of fixed plates 2 and heat sinks 1, multiple heat sinks 1 can be spliced together. After splicing the heat sink 1 and the fixed plate 2, slide the fins 3 into the limiting grooves 5 on the heat sink 1 to fix multiple fins 3, making it convenient to install the fins 3 on the heat sink 1. When dust needs to be cleaned, the fins 3 can be disassembled by directly sliding the fins 3 out of the limiting grooves 5, which is convenient for subsequent cleaning of the fins 3.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
