Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a heat sink for connector heat dissipation. Background Technology
[0002] The demand for higher-performance communication networks is increasing dramatically, and electronic devices generate more and more heat during operation. Various heat dissipation structures are widely used for cooling electronic connectors. However, when applying heat-dissipating connectors to communication equipment, the most common problems with existing heat sink mounting structures are: inconvenient connection between the connector and the heat sink; insufficient fixation between the connector and the panel, leading to loosening; and difficulty in disassembling the connector when needed. Furthermore, existing heat sinks have low heat dissipation efficiency. This invention aims to solve these problems. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a heat sink.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: it includes a rectangular heat sink, the heat sink has a top surface and a bottom surface, a first side surface and a second side surface that are perpendicular to both the bottom surface and the top surface, the top surface has heat dissipation teeth, the bottom surface of the heat sink is fixedly connected to a heat-conducting block, a base plate that covers the heat-conducting block and is fixedly connected to the bottom surface of the heat sink, the bottom surface of the heat sink has a constant air groove surrounding the outside of the heat-conducting block, the base plate covers the constant air groove, the heat-conducting block protrudes from the bottom surface, and there are several heat-conducting blocks.
[0005] In a further technical solution, the constant air channel is configured as a closed channel with two ends connected and connected to form a quadrilateral. One end of the substrate is flush with the first side of the heat sink, and the other end of the substrate has a gap with the second side of the heat sink. The end of the substrate that is flush with the heat sink has a chamfer.
[0006] In a further technical solution, the substrate has a blind hole on the side facing the heat sink, and the heat-conducting block is confined within the blind hole.
[0007] In a further technical solution, the heat-conducting block is square, and each of the four corners of the square heat-conducting block is chamfered. A gap is provided between two adjacent heat-conducting blocks.
[0008] A further technical solution involves providing two identical heat dissipation tooth blocks, with a gap three between them. The two heat dissipation tooth blocks are symmetrical with respect to the gap three, and each of the two heat dissipation tooth blocks has a spring-loaded blank area symmetrical with respect to the gap three.
[0009] The beneficial effect of this utility model is to provide a heat sink in which the base plate is inserted into the connector. In application, the spring-loaded tab is installed from one side of the top surface of the heat sink and extends to the side of the heat sink facing the base plate, where it is fastened to the external connector, thus assembling the heat sink, base plate, and heat-conducting block together with the external connector. Heat generated during signal transmission by the external connector is transferred through the base plate, then through the heat-conducting block into the heat sink, where it is dissipated to the outside through the heat dissipation teeth, achieving efficient heat dissipation. The constant airflow groove creates a flowing hot airflow channel during heat transfer, accelerating heat transfer efficiency. The chamfer allows the spring-loaded tab to be fastened to the chamfer over a relatively large distance. During installation, the spring-loaded clip is installed into the gap three from the top side of the heat sink and extends to the side of the heat sink facing the substrate. One end of the spring-loaded clip is fastened to the external connector, and the other end of the spring-loaded clip extends to a chamfer at the base and is spring-loaded and fastened to the chamfer. The spring-loaded clip is provided with a spring tab, which provides a buffer space for the fastening and installation of the spring-loaded clip in the spring-loaded blank area. This facilitates the installation of the spring-loaded clip and the heat sink of this utility model, and also makes it convenient to disassemble the spring-loaded clip and the heat sink of this utility model.
[0010] This utility model has a simple structure, high heat dissipation efficiency, and is easy to install and disassemble. Attached Figure Description

[0017] Reference Figures 1 to 4 The present invention is implemented as follows: A heat sink includes a rectangular heat sink 1, the heat sink 1 having a top surface 11 and a bottom surface 12, a first side surface 13 and a second side surface 14 perpendicular to both the bottom surface 12 and the top surface 11, the top surface 11 having heat dissipation teeth 5, the bottom surface 12 of the heat sink 1 having a heat-conducting block 2 fixedly connected to it, a base plate 3 covering the heat-conducting block 2 and fixedly connected to the bottom surface 12 of the heat sink 1, the bottom surface 12 of the heat sink 1 having a constant air groove 4 surrounding the outside of the heat-conducting block 2, the base plate 3 covering the constant air groove 4, the heat-conducting block 2 protruding from the bottom surface 12, and having a plurality of heat-conducting blocks 2.
[0018] The substrate 3 covers and fixes the heat-conducting block 2 to the bottom of the heat sink 1. When this invention is used in assembly with an external connector, the substrate 3 is inserted into the connector, and then the spring clip 8 is installed. The spring clip 8 is installed from one side of the top surface 11 of the heat sink 1 and extends to the side of the heat sink 1 facing the substrate 3, and is fastened to the external connector, thereby assembling the heat sink 1, substrate 3, and heat-conducting block 2 together with the external connector. The heat generated during signal transmission by the external connector is conducted through the substrate 3, and the heat is conducted through the heat-conducting block 2 into the heat sink 1. The heat is then dissipated to the outside through the heat dissipation teeth 5, achieving efficient heat dissipation. The constant airflow channel 4 can form a flowing hot airflow channel during heat transfer, accelerating the heat transfer efficiency.
[0019] Based on the above embodiments, as a further preferred embodiment, the constant air channel 4 is configured as a closed channel 41 with the two ends connected and connected to form a quadrilateral. When the substrate 3 transfers heat to the heat sink 1, the heat forms a hot airflow channel in the constant air channel 4 that can circulate in the closed channel 41, thereby accelerating the heat transfer.

After the substrate 3 and the bottom of the heat sink 1 are fixedly connected by laser welding, the spring clip 8 is installed from one side of the top surface 11 of the heat sink 1 and extends to the side of the heat sink 1 facing the substrate 3. One end of the spring clip 8 is fastened to an external connector, and the other end of the spring clip 8 extends to the chamfer 31 at the base and is spring-loaded and fastened at the chamfer 31. The chamfer 31 is provided to facilitate the spring clip 8 to be fastened to the chamfer over a relatively large distance range.

The chamfer 21 increases the length of the perimeter of the heat conduction block 2, thereby increasing the heat dissipation length and thus enabling the heat to be dissipated to the heat conduction block 2 more quickly.
[0022] Based on the above embodiments, as a further preferred embodiment, the heat dissipation tooth 5 is provided with two heat dissipation tooth blocks 51 with the same structure, and a gap 3 52 is provided between the two heat dissipation tooth blocks 51. The two heat dissipation tooth blocks 51 are symmetrical with respect to the gap 3 52, and each of the two heat dissipation tooth blocks 51 is provided with a spring-loaded blank area 53 symmetrical with the gap 3 52.
[0023] The heat dissipation teeth 5 can dissipate the heat on the heat sink 1 to the outside. The spring-loaded tab 8 is installed in the gap 3 52 from one side of the top surface 11 of the heat sink 1 and extends to the side of the heat sink 1 facing the substrate 3. One end of the spring-loaded tab 8 is fastened to the external connector, and the other end of the spring-loaded tab 8 extends to the chamfer 31 of the base and is spring-loaded and fastened at the chamfer 31. The spring-loaded tab 8 is provided with a spring piece. The spring piece presses on the spring-loaded blank area 53 to provide a buffer space for the fastening and installation position of the spring-loaded tab 8, which not only facilitates the installation of the spring-loaded tab 8 and the heat sink of this utility model, but also facilitates the disassembly of the spring-loaded tab 8 and the heat sink of this utility model.
[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
