The train head comprises a train head body, at least one top side protruding edge is arranged at the top of the train head body, all the top side protruding edges are distributed at the two ends of a front window of the train head body, and a top flow guide groove used for guiding airflow to flow along the top of the train head body is formed between any two adjacent top side protruding edges; the left side and the right side of the vehicle head body are each symmetrically provided with at least one side edge protruding edge, and a side edge flow guide groove used for guiding airflow to flow along the side edge of the vehicle head body is formed between any two adjacent side edge protruding edges. According to the train head, the air resistance of the high-speed train can be effectively reduced by optimizing the top and side face structures of the train head.

    本发明公开了一种列车及其车头,其中,车头包括车头本体,车头本体的顶部设有至少一条顶侧凸棱,全部顶侧凸棱分布于车头本体的前窗两端,任意相邻两条顶侧凸棱之间形成有用于引导气流沿车头本体的顶部流动的顶部导流槽;车头本体的左右两侧分别对称设有至少一条侧边凸棱,任意相邻两条侧边凸棱之间形成有用于引导气流沿车头本体的侧边流动的侧边导流槽。本发明所提供的列车的车头通过优化其顶部及侧面结构,能有效减小高速列车的空气阻力。
