Plate-penetrating pipeline structure

The utility model relates to the field of engine unit equipment, in particular to a plate penetrating pipeline structure which comprises a unit shell, an exhaust pipeline and a cooling sleeve. The side wall of the unit shell is provided with a connector, the cooling sleeve is arranged in the connector, and a cooling medium cavity is formed in the cooling sleeve. The cooling sleeve is provided with a mounting hole for communicating the interior and the exterior of the unit shell, and the exhaust pipeline penetrates out of the interior of the unit shell along the mounting hole. The plate-penetrating pipeline structure provided by the utility model can prevent the high-temperature pipeline from generating adverse effects on the installation structure and the sealing performance of the case shell at the plate-penetrating position. 本实用新型涉及发动机组设备领域，尤其涉及一种穿板管路结构，包括机组壳体、排气管道和冷却套筒；所述机组壳体的侧壁设有接口，所述冷却套筒设置在接口内，所述冷却套筒的内部设有冷却介质腔室；所述冷却套筒设有连通机组壳体的内部和外部的安装孔，所述排气管道自机组壳体的内部沿安装孔穿出。本实用新型提供的穿板管路结构可避免高温管道对机箱壳体在穿板位置的安装结构和密封性产生不利影响。
