Title (EN) THERMALLY CONDUCTIVE MOLDED RESIN ARTICLE
(FR) ARTICLE EN RÉSINE MOULÉ THERMIQUEMENT CONDUCTEUR
(JA) 熱伝導性樹脂成型品
Abstract:
(EN) Provided is a thermally conductive molded resin article that can be inexpensively mass-produced and that exhibits a low thermal resistance value as a result of reducing internal thermal resistance by high filling and reducing interfacial thermal resistance by improving cutting precision. The thermally conductive molded resin article is characterized by comprising a resin and thermally conductive fillers including a first thermally conductive filler and a second thermally conductive filler having a smaller particle size than the first thermally conductive filler. The thermally conductive molded resin article is also characterized in that: the first thermally conductive filler has an aspect ratio of 10 or more and is oriented approximately in the thickness direction of the thermally conductive molded resin article; the resin is a silicone resin, an acrylic rubber, or a fluororubber; and the second thermally conductive filler has a thermal conductivity surpassing 5W/mK.
(FR) La présente invention concerne un article en résine moulé thermiquement conducteur qui peut être produit en masse de manière bon marché et qui fait preuve d’une faible valeur de résistance thermique en résultat de la réduction de la résistance thermique interne par charge élevée et réduction de la résistance thermique interfaciale en améliorant la précision de découpe. L’article en résine moulé thermiquement conducteur est caractérisé en ce qu’il comprend une résine et des charges thermiquement conductrices comprenant une première charge thermiquement conductrice et un seconde charge thermiquement conductrice ayant une taille de particule plus petite que la première charge thermiquement conductrice. L’article en résine moulé thermiquement conducteur est également caractérisé en ce que : la première charge thermiquement conductrice présente un rapport d’aspect de 10 ou plus et est orientée approximativement dans le sens de l’épaisseur de l’article en résine moulé thermiquement conducteur ; la résine est une résine de silicone, un caoutchouc acrylique, ou un caoutchouc fluoré ; et la seconde charge thermiquement conductrice présente une conductivité thermique excédant 5 W/mK.
(JA) 安価に大量生産が可能な、高充填による内部熱抵抗の低減と、カット精度向上による界面熱抵抗の低減と、によって、低い熱抵抗値を発揮する熱伝導性樹脂成形品を提供する。樹脂と、第一熱伝導性フィラー及び前記第一熱伝導性フィラーより小さい粒径を有する第二熱伝導性フィラーを含む熱伝導性フィラーと、を含み、前記第一熱伝導性フィラーが10以上のアスペクト比を有するとともに前記熱伝導性樹脂成形品の略厚み方向に配向しており、前記樹脂がシリコーン樹脂、アクリルゴム又はフッ素ゴムであり、前記第二熱伝導性フィラーが5W/mK超の熱伝導率を有すること、を特徴とする熱伝導性樹脂成形品。
