| Zusammenfassung: | To provide a rib structure capable of reducing noise and vibration while maintaining heat exhausting performance.SOLUTION: A rib structure according to the present invention comprises: a columnar pole rib 11 arranged at each vertex position of a regular hexagon; and an installation rib 12 in an equilateral hexagram-type peripheral shape, for which each vertex engages with respective side faces of all the pole ribs 11 arranged at each vertex position of the regular hexagon. The installation rib 12 is provided with a regular hexagonal prism-shaped hollow part 12a in a center thereof, and the hollow part 12a whose inner wall faces are each oriented facing the nearest pole rib 11 can reduce noise and vibration while maintaining heat exhausting performance.SELECTED DRAWING: Figure 1
【課題】廃熱性能を維持しつつ騒音及び振動を低減することができるリブ構造を提供する。【解決手段】本発明に係るリブ構造は、正六角形の各頂点位置に配列された柱状の支柱リブ１１と、上記正六角形の各頂点位置に配列された全ての支柱リブ１１の側面に対し各頂点が嵌合する、等辺六芒星型の周縁形状である架設リブ１２とを備え、架設リブ１２は、中心に正六角柱状の中空部１２ａが形成され、中空部１２ａは、その各内壁面がそれぞれ最も近い支柱リブ１１に正対する向きとなっていることにより、廃熱性能を維持しつつ騒音及び振動を低減することができる。【選択図】図１ |
