[0002] With the rapid development of electronic technology, various electronic devices such as computers, mobile phones, tablet computers, etc. have penetrated into people's daily life and work. These electronic devices will generate a lot of heat when working. If the heat cannot be dissipated in time and effectively, it will have an adverse effect on the performance and service life of the equipment. Therefore, heat dissipation technology has become one of the hot spots in the field of electronic equipment research, and heat dissipation copper sheet is one of the important heat dissipation devices, which is widely used in various electronic devices.

[0003] The basic structure of a heat sink usually includes a copper substrate and multiple heat sink fins. The copper substrate is the main part of the heat sink, which is used to contact the heat source and transfer heat to the heat sink fins. The heat sink fins improve the heat dissipation effect by increasing the heat dissipation area. In order to adapt to electronic devices of different shapes and specifications, existing heat sinks mostly adopt a combined connection method, that is, multiple heat sink fins are connected to the copper substrate by welding, screwing, etc.

[0004] However, the existing combined heat sink copper sheet is usually composed of a number of heat sink fins arranged in parallel with equal intervals to form a heat sink group. When the heat dissipation effect of the heat sink group still cannot meet the actual heat dissipation needs, it is usually necessary to increase the heat dissipation area by adding heat sink fins. The existing copper tubes and heat sink fins are firmly assembled after leaving the factory, which is not conducive to users to disassemble and add heat sink fins according to needs, making it inconvenient for users to use copper sheets in combination, resulting in the need to replace the heat sink copper sheet group as a whole, thereby generating a large use cost and affecting practicality.
