| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a heat radiation device that can achieve sufficient heat radiation even at the downwind of a heat sink.SOLUTION: A heat radiation device 1 includes plural fins 3 which are provided to another surface 2c of a base 2b having plural heating bodies secured to one surface 2a thereof so that the tips 6a, 6b of the plural fins 3 are protruded at a predetermined height inside a cylindrical large air duct. The heat radiation device 1 is provided with air blowers 5a, 5b for blowing air in one direction in the large air duct. The plural fins 3 are provided in parallel so as to configure a small air duct along one direction, and notches are provided from the windward side on the tip side facing the windward side of every predetermined number of fins 3a out of the plural fins.SELECTED DRAWING: Figure 1
【課題】ヒートシンクの風下においても充分な放熱が得られる放熱装置を提供するものである。【解決手段】本発明の放熱装置１は、一方の面２ａに複数の発熱体を取り付けた基台２ｂの他方の面２ｃに設けられた複数のフィン３を筒状の大風路の内に先端６ａ、６ｂを所定の高さで突出させた放熱装置に於いて、大風路の内で一方の方向へ送風を行う送風装置５ａ、５ｂを設け、複数のフィン３を一方の方向に沿って小風路を構成するように並行に設けると共に、複数のフィンの内の所定の数毎のフィン３ａの風上側に面する先端の側に風上側から切り欠きを設けるものである。【選択図】図１ |
