PROBLEM TO BE SOLVED: To prevent overheat of an engine by improving the cooling effect of a radiator in a working machine.SOLUTION: The engine cooling device for working machine stands a radiator (91) circulating a cooling water outside an engine (9). In the device, a cooling fan (90) between the engine (9) and the radiator (91), and a cooler such as an intercooler (93) connected to a supercharger (30) along the outside of the radiator (91) are installed. The device is configured so that the outdoor air sucked while detouring the periphery of a cooler disposed apart from a first outdoor air passage face (91a) is introduced into the passage face (91a) by inclining a second outdoor air passage face (93a) prepared for the cooler to a first outdoor air passage face (91a) prepared for the radiator (91). Besides, the device is configured to blow out an inside air by inverse rotation of the cooling fan (90), and the outside face of the second outdoor air passage face (93a) is inclined to be located inside the cooler body as becoming the lower side of the outside face.SELECTED DRAWING: Figure 10

    【課題】ラジエータの冷却効果を向上させて、エンジンのオーバーヒートを防止する。【解決手段】エンジン(9)の外側に冷却水を循環するラジエータ(91)を立設し、エンジン(9)とラジエータ(91)の間に冷却ファン(90)を設け、ラジエータ(91)の外側に沿って過給器(30)に接続されるインタークーラ(93)等の冷却器を設けた作業機のエンジン冷却装置において、ラジエータ(91)に備えた第1外気通過面(91a)に対して冷却器に備えた第2外気通過面(93a)を傾け、第1外気通過面(91a)から離間して配置された冷却器の周囲を迂回して吸入される外気が第1外気通過面(91a)へ導入される構成とする。また、冷却ファン(90)を逆回転することで内気を吹出す構成とし、第2外気通過面(93a)の外側面を下部側ほど機体内側に位置するように傾斜させる。【選択図】図10
