PROBLEM TO BE SOLVED: To provide an oriented flexible heat-conducting material.SOLUTION: The oriented flexible heat-conducting material is disclosed. Main ingredients of the oriented flexible heat-conducting material are silicone rubber and anisotropic heat-conducting filler. Multiple continuous heat-conducting paths that are parallel to each other are formed in the oriented flexible heat-conducting material, and the heat-conducting paths are formed by continuously arranging the anisotropic heat-conducting filler, that fill the inside of the silicone rubber, in lines in a heat-conducting path direction. The oriented flexible heat-conducting material has a desirable heat-conducting property in a specific direction and has desirable flexibility, can be in desirable contact with an interface to produce quite low interface thermal resistance, and can greatly improve a heat dissipation effect. Embodiments of the present invention further provide a forming process and an application of the oriented flexible heat-conducting material. 【課題】配向可撓性熱伝導材料を提供する。【解決手段】本発明は、配向可撓性熱伝導材料を提供し、前記配向可撓性熱伝導材料の主成分は、シリコーンゴム及び異方性熱伝導充填剤である。互いに平行である複数の連続した熱伝導パスが前記配向可撓性熱伝導材料内に形成され、且つ、熱伝導パス方向に複数列に、前記シリコーンゴム内に充填された異方性熱伝導充填剤を連続的に配置することにより、熱伝導パスが形成される。配向可撓性熱伝導材料は、望ましい可撓性を有するとともに特定の方向に望ましい熱伝導特性を有し、し、きわめて低い界面熱抵抗を生成するように界面と望ましく接触可能であり、及び放熱効果を大きく改善可能である。本発明の実施形態は、前記配向可撓性熱伝導材料の形成プロセス及び用途をさらに提供する。【選択図】図２
