14.Orientation material is a type of material with special structure and properties, characterized by its high thermal conductivity, absorption, and shielding capabilities in a particular direction. The uniqueness of this material lies in the arrangement of its internal molecules or atoms, enabling it to exhibit excellent performance in specific directions.
Phase change conduction represents an efficient and rapid heat transfer method. Its key characteristic lies in leveraging the ultra-low flow resistance of vacuum negative pressure and the physical change of liquid vaporization. This process entails absorbing a substantial amount of heat instantaneously, leading to the rapid dispersion of vapor to fill the entire cavity within the vacuum negative pressure chamber. As a result, this technology achieves high thermal conductivity and nearly superconductive capability. The integration of copper powder capillary sintering technology and aluminum powder capillary sintering technology not only accelerates the rate of liquid vaporization but also enhances the product’s resistance to gravity. By leveraging these technologies, heat pipes, VC (vapor chamber), and modules have been technologically improved and widely used, and even a 3D phase change superconductive radiator has been developed.
Immersion cooling liquid serves as a widely used cooling medium in the industrial field, employed to reduce the temperature of equipment, machinery, or workpieces to maintain them within an appropriate operating temperature range. Immersion cooling liquids are typically used in metal processing, electronic device cooling, chemical reaction control, and other related fields.
Functional powder pretreatment refers to a series of processing steps carried out before preparing functional powder materials. The aim is to enhance their performance, stability, and processability. These pretreatment steps typically involve manipulation of particle size, dispersion, surface properties, and other factors, which profoundly affect the material’s performance across various application fields. Below are several potential research directions related to functional powder pretreatment.
