The invention provides an overhead rainproof heat dissipation system suitable for a railway engineering vehicle. The overhead rainproof heat dissipation system comprises a heat dissipation room, an air blowing type heat dissipation device, a mounting base, a shock absorber and a vehicle body assembling rainproof assembly, wherein the heat dissipation room is composed of a partition wall and a heat dissipation room ceiling, the partition wall is used for separating the heat dissipation room from a power room and a hydraulic pressure room of a vehicle, the blowing type radiator is installed at the top in the heat dissipation room through an installation base and a shock absorber, and the radiator is communicated with the power room through an engine intercooling pipeline, rainproof shutters serving as exhaust inlets are arranged on the two sides of the power room and the two sides of the heat dissipation room; a rain-proof shutter capable of being opened and closed is arranged on a ceiling of the heat dissipation room, a rain-proof skirt edge is arranged on the periphery of the lower portion of the heat dissipation room, the rain-proof assembly assembled on the vehicle body comprises a rain-proof turnup edge fixed to the vehicle body, and the rain-proof turnup edge and the rain-proof skirt edge are matched to form a labyrinth type rain-proof structure. According to the rainproof structure, a labyrinth structure is formed by matching the skirt edges and the turnup edges, so that rainwater is blocked and is not easy to flow into the heat dissipation room.
本申请提供了一种适用于铁路工程车辆的顶置式防雨散热系统,包括散热间、吹风式散热器、安装座、减震器以及车体配装防雨组件;其中:散热间由用于将散热间和车辆的动力间及液压间隔开的隔墙和散热间顶棚构成,所述吹风式散热器通过安装座和减震器安装于散热间内位于顶部的位置,散热器与所述动力间通过发动机中冷管路相连通,动力间及散热间两侧设有作为吸风口的防雨百叶窗;所述散热间的顶棚上设有能够开合的防雨百叶窗,所述散热器的下部周边设有防雨裙边,所述车体配装防雨组件包括固定在车体上的防雨翻边,防雨翻边与防雨裙边配合构成迷宫式防雨结构。这种防雨结构利用裙边和翻边配合形成的迷宫结构,使雨水受到阻挡,不易流进散热间。
