Cooling structure for urea aqueous solution conduit
In a working vehicle, an exhaust gas aftertreatment device is provided in an engine compartment that is adjacent to a cooling fan through which cooling air is supplied to a heat exchanger. The exhaust gas aftertreatment device includes a selective catalytic reduction device in which ammonia obtained from a urea aqueous solution is used as a reduction-causing agent. A urea aqueous solution pipe through which the urea aqueous solution is supplied is laid to the selective catalytic reduction device through the engine compartment. In the engine compartment, a pipeline-forming member having pipelines in which the urea aqueous solution pipe is installed. The cooling air sucked by a cooling fan flows into the pipelines.
