SUPPORT STRUCTURE OF HEAT EXCHANGER FOR WORK VEHICLE, AND WORK VEHICLE
To facilitate access to an engine room.SOLUTION: A shroud of a support structure of a heat exchanger includes a base end covering an outer periphery of a first surface of the heat exchanger and a terminal having a substantially circular shape when viewed from a thickness direction. A support frame supports the heat exchanger and the shroud to expose the terminal and a second surface of the heat exchanger. A vehicle body frame has an opening having a support wall as a part of an outer circumference. A cooling fan includes a fan rotating shaft extending along a fan rotation axis passing through the opening and a plurality of blades provided around the fan rotating shaft, and is configured to generate cooling air. When the heat exchanger is in a first position facing the cooling fan, the terminal of the shroud radially surrounds the cooling fan such that the cooling air passes through the first and second surfaces. When the support frame is positioned at a second position where the heat exchanger exposes the opening to an outside of the vehicle body frame, the fan rotating shaft and the plurality of blades are exposed.SELECTED DRAWING: Figure 6
【課題】エンジン室へのアクセスが容易となる。【解決手段】熱交換器の支持構造に係るシュラウドは、熱交換器の第１面の外周を覆う基端部と、厚さ方向から見て略円形の形状を有する末端部とを含む。支持フレームは、末端部と熱交換器の第２面とを露出させるように熱交換器とシュラウドとを支持する。車体フレームは、支持壁を外周の一部とする開口部を有する。冷却ファンは、開口部を通るファン回転軸線に沿って延びるファン回転シャフトと、ファン回転シャフトの周囲に設けられる複数の羽根とを備え、冷却風を起こすように構成される。熱交換器が冷却ファンに対向する第１位置に位置するとき、シュラウドの末端部は、冷却風が第１面と第２面とを通り抜けるように径方向において冷却ファンの周囲を覆う。熱交換器が開口部を車体フレームの外部に露出する第２位置に支持フレームが位置するとき、ファン回転シャフトと複数の羽根とがむき出しになっている。【選択図】図６
