PROBLEM TO BE SOLVED: To improve a cooling aeraulic device for cooling a railway vehicle element.SOLUTION: The aeraulic device 10 includes a conductor 24 designed to be disposed on the roof of a railway vehicle, and the conductor continuously includes a front part 32 substantially extending in a longitudinal direction with respect to the railway vehicle and having a front opening 28 for sucking air, a center part 34 for housing an element 12 to be cooled, and a rear part 36 having a rear opening 30 for discharging exhaust air. The surface 24 of the conductor 24 having a cross section progressively changes so as to cause acceleration of an airflow in the conductor from the front opening 28 to the rear opening 30 by using a venturi effect.SELECTED DRAWING: Figure 3
【課題】鉄道車両の要素を冷却するための冷却エアローリック装置の改良に関する。【解決手段】エアローリック装置10は前記鉄道車両の屋根に配置されるように設計され且つ導管24を備え、前記導管は、鉄道車両に対して実質的に長手方向に延び、且つ、空気の取り入れ用の前方開口部28を備える前方部分32と、冷却すべき前記要素12が収納される中央部分34と、排気の放出用の後方開口部30を備える後方部分36とを連続的に含むエアローリック装置10に関する。導管24の横断面を有する表面24が、前方開口部28から後方開口部30へ、ベンチュリー効果を用いて導管内の空気の流れの加速を引き起こすように漸進的に変化する。【選択図】図3
