REDUCING AGENT TANK AND WORK VEHICLE

摘要

A reducing agent tank is provided which enables detachment of a top cover and a heat exchanger while maintaining a long path length of a heat exchanger in a reducing agent tank. A first pipeline and a second pipeline respectively have extension portions which extend from lower ends of a suspended portion along a bottom face toward a side face of a container main body, and rising portions which extend from leading ends of the extension portions along the side face toward an upper face of the container main body. A length of the extension portions along the bottom face is larger than a maximum inside length of an opening. The rising portions and a turning portion form a leading end bent portion, and a rising length of the leading end bent portion is smaller than a minimum inside length passing through a center of the opening.

主权项

1. A reducing agent tank, comprising:
a container main body which has an opening formed in an upper face and stores a reducing agent; a heat exchanger which performs heat exchange with said reducing agent; and a top cover which covers said opening and supports said heat exchanger, said heat exchanger including a first pipeline which guides a heat exchange medium into said container main body, a second pipeline which allows a heat exchange medium to flow out from said container main body, and a turning portion, said first pipeline and said second pipeline communicating with each other through said turning portion, each of said first pipeline and said second pipeline having a suspended portion which extends from said top cover toward a bottom face of said container main body, an extension portion which extends from a lower end of said suspended portion along said bottom face toward a side face of said container main body, and a rising portion which extends from a leading end of said extension portion along said side face toward said upper face of said container main body, a length of said extension portion along said bottom face being larger than a maximum inside length of said opening, said rising portion of said first pipeline, said rising portion of said second pipeline, and said turning portion forming a leading end bent portion of said heat exchanger, a rising length of said leading end bent portion along said side face being smaller than a minimum inside length passing through a center of said opening.
