High thermal conductivity fiber: opening a new era of thermal management

In today’s era of rapid technological development, thermal management issues have become one of the key challenges faced by many fields. From the heat dissipation needs of electronic equipment to the temperature regulation of functional clothing, from thermal protection in aerospace to thermal conduction optimization in the field of new energy, high thermal conductivity fibers have gradually become the focus of research and industry with their unique performance and broad application prospects.

With the rapid development of aerospace, electronic chips, artificial intelligence and other fields, the application needs of high-power heat dissipation and heat dissipation have put forward higher and higher requirements for high thermal conductivity materials. High thermal conductivity fibers, such as mesophase pitch-based carbon fibers, boron nitride fibers, carbon nanotube fibers, graphene fibers, etc., not only show excellent high thermal conductivity, but also have high mechanical strength, directional thermal conductivity, and weavability. They are ideal materials for structural and functional integration of high-power heat dissipation applications.

1. Excellent thermal conductivity: The most notable feature of high thermal conductivity fiber is its excellent thermal conductivity. Compared with traditional fibers, high thermal conductivity fibers can transfer heat more quickly, effectively reduce local temperature, and improve heat conduction efficiency. This feature gives high thermal conductivity fibers unique advantages in heat dissipation and heat conduction.

2. Good mechanical properties: In addition to thermal conductivity, high thermal conductivity fibers usually have good mechanical properties, such as high strength, high toughness, and wear resistance.

3. Lightweight and flexible: High thermal conductivity fibers usually have a lighter weight and good flexibility, and can be woven, woven or composited according to different needs to make materials of various shapes and structures.

4. Chemical stability: High thermal conductivity fibers generally have good chemical stability and can maintain their stable performance under different chemical environments. This allows high thermal conductivity fibers to be used in various harsh working conditions, such as high temperature, high pressure, corrosive environment, etc.

Application areas of high thermal conductivity fibers

1. Heat dissipation of electronic equipment: As the performance of electronic equipment continues to improve, its heat dissipation problem has become increasingly prominent. High thermal conductivity fibers can be used as heat dissipation materials and applied to radiators, heat sinks and other components of electronic equipment to effectively improve the heat dissipation efficiency of electronic equipment, reduce operating temperatures, and extend the service life of equipment.

2. Functional clothing: High thermal conductivity fibers can be used in functional clothing, such as sportswear, outdoor clothing, etc., to achieve the regulation of human body temperature. In a cold environment, high thermal conductivity fibers can quickly transfer the heat generated by the human body, keep the temperature inside the clothing in a relatively stable state, reduce the accumulation of heat inside the clothing, thereby avoiding sweating due to overheating, and then preventing sweat from making the human body feel cold in a low temperature environment; in a hot environment, high thermal conductivity fibers can quickly transfer external heat to the surface of the human body, dissipate heat through sweat evaporation, and keep the body cool.

3. Aerospace: In the field of aerospace, high thermal conductivity fibers can be used as thermal protection materials in the outer shell, engine and other parts of aircraft, effectively reducing the heat generated by aircraft during high-speed flight and improving the safety and reliability of aircraft. In addition, high thermal conductivity fibers can also be used in electronic equipment heat dissipation, satellite thermal control and other aspects in the field of aerospace.

4. New energy field: In the field of new energy, high thermal conductivity fibers can be used as battery separators, electrode materials, etc. to improve the charging and discharging efficiency and safety of batteries. In addition, high thermal conductivity fibers can also be used in the thermal management of new energy equipment such as solar cells and fuel cells to improve the performance and stability of equipment.
