Abstract: front page image
(EN)A heat sink facilitates the flow of surrounding air, and enables improved heat dissipation. The heat sink is provided with: a planar base portion 1; a planar protruding-piece portion 2a protruding with respect to the base portion 1 toward one side in a thickness direction of the base portion 1; and a tubular projection 2d which protrudes with respect to the protruding-piece portion 2a in a thickness direction of the protruding-piece portion 2a, and of which the inside is bored in the protruding direction. A plurality of heat dissipating portions 2a are provided along the surface of the base portion 1, and a plurality of the tubular projections 2d are provided along the surface of each protruding-piece portion 2a.
(FR)Un dissipateur thermique facilite l'écoulement de l'air environnant et permet une meilleure dissipation de la chaleur. Le dissipateur thermique comporte : une portion de base plane 1; une portion en saillie plane 2a faisant saillie par rapport à la portion de base 1 vers un côté dans la direction de l'épaisseur de la portion de base 1; et une projection tubulaire 2d qui fait saillie par rapport à la portion en saillie 2a dans la direction de l'épaisseur de la portion en saillie 2a, et dont l'intérieur est percé dans la direction en saillie. Une pluralité de portions de dissipation de chaleur 2a sont disposées le long de la surface de la portion de base 1, et une pluralité de projection tubulaires sont disposées le long de la surface de chaque portion de pièce en saillie 2a.
(JA)周囲の空気を流動させ易くし放熱性を向上する。板状のベース部1と、該ベース部1に対し該ベース部1の厚み方向の一方へ突出した板状の突片部2aと、該突片部2aに対し該突片部2aの厚み方向へ突出するとともにその突出方向へ内部が貫通した筒状突起2dとを備え、放熱部2aは、ベース部1の面に沿って複数設けられ、筒状突起2dは、各突片部2aの面に沿って複数設けられる。
