    • PROBLEM TO BE SOLVED: To avoid deterioration of air flows due to collision of exhaust airs through the first and the second exhaust ports and to reduce noise on the side of a construction machine, in a cooling structure including the first exhaust port discharging air that has been cooled in the axial direction of an engine output shaft and the second exhaust port discharging the air upward which are located close to each other.SOLUTION: The first exhaust port 15 formed in a bonnet 11 composing an engine guard 4 and the second exhaust port 16 formed in a fixed hood 13 are located close to each other. An exhaust air guide 19 for changing a flow direction of air discharged in the axial direction of the engine output shaft 6a from the first exhaust port 15 into an obliquely upward direction on the windward side of the second exhaust port 16, is provided at an opening edge on the leeward side of the second exhaust port 16.
    • 要解决的问题:为了避免由于第一排气口和第二排气口的排出气体的碰撞引起的空气流的劣化,并且降低了建筑机械侧的噪音,在包括第一排气口排出空气的冷却结构中, 在发动机输出轴的轴向上被冷却,第二排气口向上排出彼此靠近的空气。解决方案:形成在构成发动机保护罩4的发动机罩11中的第一排气口15和第二排气口 16形成在固定罩13中。 用于将发动机输出轴6a的轴向排出的空气的流动方向从第一排气口15向第二排气口16的迎风侧的倾斜向上改变的排气引导件19设置在开口 边缘在第二排气口16的背风侧。
