Abstract

The invention relates to the technical field of heat dissipation materials, and discloses a heat dissipation material and its processing technology. The processing technology includes the following steps: raw material selection, compounding, polishing treatment, and annealing treatment; by rolling and compounding pure nickel strips and pure copper strips, Making full use of the principle of plastic deformation of metal and atomic diffusion between metals, the pure nickel strip and pure copper strip are combined through a certain positive pressure and mechanical occlusion. The products produced by this processing technology not only have high heat dissipation performance, but also It has strong strength and toughness, which can fully meet the heat dissipation requirements; the heat dissipation and thermal conductivity can be adjusted by adjusting the thickness ratio of pure copper and pure nickel, and the process can be adjusted flexibly. It only needs to change the thickness of the metal before compounding, and the melting The content and influence of trace elements need to be continuously adjusted, which is cumbersome and high in development costs; at the same time, the nickel surface of the compounded product will not rust even in an environment where the temperature rises, and there is no phenomenon that affects the heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of heat dissipation materials, in particular to a heat dissipation material and its processing technology. Background technique [0002] With the intelligent application of mobile phone functions, the quality of life has been greatly improved, and the functional requirements of mobile phones are constantly pursuing more intelligent, which requires mobile phone chips to provide excellent computing power. Of course, high-speed computing and processing will generate heat. The faster the computing speed and the longer the running time, the calorific value will increase accordingly. If the heat is not dissipated in time, the temperature of the mobile phone will gradually rise. It will endanger the safety of the battery and the damage of the chip, so the heat dissipation function of the mobile phone cannot be ignored. [0003] At present, the best heat dissipation materials in mobile phones are mainly copper allo...
