The invention provides an automatic water-cooled light-weight fireproof partition wall for a railway vehicle. The automatic water-cooled light-weight fireproof partition wall comprises a partition wall body, and a plurality of first heat dissipation pieces are installed in the partition wall body; a trigger device is installed on the partition wall body and used for controlling the first heat dissipation pieces to be started; the trigger device comprises an expansion rubber strip and a switch button; when a fire occurs, the expansion rubber strip is heated to expand and then extrudes the switch button, so that the first heat dissipation pieces are controlled to work to dissipate heat and cool the partition wall body; the partition wall body comprises a fixed partition wall and a movable partition door, and a second heat dissipation piece is installed in the movable partition door; and the trigger device is installed between the fixed partition wall and the movable partition door, the expansion rubber strip is fixed to the side end of the movable partition door, and the switch button is installed on the fixed partition wall and corresponds to the expansion rubber strip. According to the automatic water-cooled light-weight fireproof partition wall for the railway vehicle, the defect that an existing fireproof partition wall cannot meet the requirements for light weight and fire-resistant integrity is overcome.

    本发明提供了一种轨道车辆用自动水冷式轻量化防火隔墙,包括隔墙本体,隔墙本体内安装有多个第一散热件;隔墙本体上安装有触发装置,触发装置用于控制开启第一散热件;触发装置包括膨胀胶条和开关按钮;当发生火情时,膨胀胶条受热膨胀后挤压开关按钮,从而控制第一散热件工作对隔墙本体进行散热降温;隔墙本体包括固定隔墙以及活动隔门,活动隔门内安装有第二散热件;触发装置安装在固定隔墙和活动隔门之间,膨胀胶条固定在活动隔门侧端,开关按钮安装在固定隔墙上并与膨胀胶条对应设置;本发明提供的一种轨道车辆用自动水冷式轻量化防火隔墙,克服了现有防火隔墙不能兼顾轻量化和耐火完整性要求的缺陷。
