To improve cooling performance of a power generation unit in a compact layout.SOLUTION: A cooling structure of a power generation unit includes: a radiator 37 connected to a power generator 30 and an inverter 35 through a cooling pipe; electric fans 31, 32 located adjacent to the radiator 37; and an introduction pipe 40 which is disposed between the radiator 37 and a power generation engine 20 and enables air outside the unit to circulate to the power generation engine 20. The introduction pipe 40 is provided with an introduction opening part for introducing air. The radiator 37 is disposed so as to overlap with a part of the introduction opening part and air which has passed through the radiator 37 may flow from the introduction opening part into the introduction pipe 40.SELECTED DRAWING: Figure 5

    【課題】コンパクトなレイアウトで発電ユニットの冷却性能を向上させる。【解決手段】発電ユニットの冷却構造は、冷却配管を介して発電機30及びインバータ35に接続されているラジエータ37と、ラジエータ37に隣接する電動ファン31,32と、ラジエータ37と発電用エンジン20との間に配置され、ユニット外側の空気を発電用エンジン20に向けて流通可能な導入配管40とを備え、導入配管40には、空気を導入する導入開口部が設けられ、ラジエータ37は、導入開口部の一部に重なるように配置され、ラジエータ37を通る抜けた空気は、導入開口部から導入配管40に流入可能に構成されている。【選択図】図5
