Title (EN) HEAT SINK
(FR) DISSIPATEUR THERMIQUE
(JA) ヒートシンク
Abstract:
(EN) The present invention provides a heat sink that suppresses formation of a boundary layer on a surface of a heat dissipation fin, and that has excellent heat radiation performance even in locations other than the windward side of cooling air. The heat sink has: a base plate; at least one first heat dissipation fin that is thermally connected to the base plate; and at least one second heat dissipation fin that is adjacent to a side end part of the first heat dissipation fin, and is thermally connected to the base plate, wherein the surface of the first heat dissipation fin is not parallel to the surface of the second heat dissipation fin, and at least one of the second heat dissipation fins is provided at a position lower than at least one of the first heat dissipation fins in the vertical direction with respect to the base plate surface.
(FR) La présente invention concerne un dissipateur thermique qui supprime la formation d'une couche de délimitation sur une surface d'une ailette de dissipation de chaleur, et qui a une excellente performance de rayonnement thermique même dans des emplacements autres que le côté au vent de l'air de refroidissement. Le dissipateur thermique comprend : une plaque de base ; au moins une première ailette de dissipation de chaleur qui est reliée thermiquement à la plaque de base ; et au moins une seconde ailette de dissipation de chaleur qui est adjacente à une partie d'extrémité latérale de la première ailette de dissipation de chaleur, et est reliée thermiquement à la plaque de base, la surface de la première ailette de dissipation de chaleur n'étant pas parallèle à la surface de la seconde ailette de dissipation de chaleur, et au moins une des secondes ailettes de dissipation de chaleur est disposée à une position inférieure à au moins l'une des premières ailettes de dissipation de chaleur dans la direction verticale par rapport à la surface de plaque de base.
(JA) 放熱フィンの表面における境界層の形成を抑制し、冷却風の風上側以外の部位でも優れた放熱性能を有するヒートシンクを提供する。 ベースプレートと、該ベースプレートと熱的に接続された少なくとも1つの第1の放熱フィンと、該第1の放熱フィンの側端部と隣接し、該ベースプレートと熱的に接続された少なくとも1つの第2の放熱フィンと、を有し、前記第1の放熱フィンの表面が、前記第2の放熱フィンの表面に対して平行ではなく、前記ベースプレート表面に対し鉛直方向において、前記第2の放熱フィンの少なくとも1つが、前記第1の放熱フィンの少なくとも1つよりも低い位置に設けられているヒートシンク。
