PROBLEM TO BE SOLVED: To totally improve cooling performance of a heating element.SOLUTION: A duct 10 includes: first projections 20A-20E extending in a flow direction of cooling air and second projections 31-36 extending in a direction intersecting a flow direction of cooling air. The first projections 20A-20E extend so as to enlarge the flow of cooling air in a width direction at the inside of an upstream side passage enlargement section 14, and extend so as to reduce the flow of cooling air in a width direction at a downstream side passage reduction section 15.SELECTED DRAWING: Figure 3
【課題】発熱体の冷却性能を全体的に高める。【解決手段】ダクト10には、冷却風の流れ方向に延びる第1突出部20A〜20Eと、冷却風の流れ方向と交差する方向に延びる第2突出部31〜36とが設けられている。第1突出部20A〜20Eは、上流側通路拡大部14内において冷却風の流れを幅方向に拡大するように延びるとともに、下流側通路縮小部15において冷却風の流れを幅方向に縮小させるように延びている。【選択図】図3
