Heat sinks are devices used to dissipate heat from heat-generating electronic components in electrical appliances. They are often made of aluminum alloy, brass, or bronze in plate, sheet, or multi-sheet forms. For example, a computer's CPU requires a relatively large heat sink, and heat sinks are also used in power tubes, deflection tubes, and amplifiers in televisions. Generally, a layer of thermal grease is applied to the contact surface between the electronic component and the heat sink during use to more effectively conduct the heat generated by the component to the heat sink, which then dissipates it into the surrounding air.
The finned heat sink includes a main board, with heat dissipation fins arranged on the upper outer surface of the main board. The upper outer surface of the heat dissipation fins and the upper outer surface of the main board are both provided with grooves. A connecting block is arranged in front of the heat dissipation fins on the upper outer surface of the main board. The upper end of the connecting block is equipped with a connecting frame, and the rear outer surface of the connecting frame has a welding block. A flow guide plate is arranged at the upper end of the heat dissipation fins at the rear end of the welding block. Both the upper outer surface of the connecting block and that of the main board are provided with fixed screws. One side of the connecting block on the upper outer surface of the main board is equipped with a connecting plate. The finned heat sink described in this utility model can improve its heat dissipation performance and facilitate disassembly, bringing better prospects for use.
Small finned heat sinks (or called heat sinks) are made from aluminum alloy plates through stamping processes and surface treatment, while large finned heat sinks are formed from extruded aluminum alloy profiles, followed by machining and surface treatment. They come in various shapes and sizes for different device installations and power consumption requirements. Heat sinks are generally standard parts but can also provide profiles that users can cut to specific lengths to create non-standard heat sinks based on their requirements. The surface treatment of heat sinks includes electrophoretic painting or black anodizing, aimed at improving heat dissipation efficiency and insulation performance. Natural cooling can improve efficiency by 10-15%, while ventilated cooling can improve it by 3%. Electrophoretic paint can withstand voltages of 500-800V.

The hardware industry is developing very rapidly, with traditional hardware markets mainly concentrated in mechanical hardware.Building hardware, decorative hardware, and daily-use hardware are several major sectors. The trend of industrial concentration in the hardware industry is also very obvious, with China's hardware industry mainly concentrated in economically developed provinces and regions such as Guangdong, Zhejiang, Jiangsu, Shanghai, Hebei, and Shandong. Traditional hardware enterprises have relatively single products; many companies only provide supporting parts for other manufacturing enterprises, showing strong dependence on manufacturing enterprises and slow response to market demand. Traditional hardware enterprises do not focus on new product development and market extension, leading to a lack of sustained competitive ability. Faced with increasingly specialized market demands and intensifying competition, many initially fast-developing hardware enterprises feel powerless in subsequent developments.
