[0038] 发电机 40的前部下方自左至右并列设置有逆变器 50及蓄电池 20。
[0039] 逆变器 50在整流发电机 40发出的电力之后,转换成规定频率的交流电力后输出。 逆变器 50配置在控制装置 70的下侧，即蓄电池 20的左侧附近。
[0040] 蓄电池 20是给用于起动发动机 30起动装置、逆变器 50的控制部、控制面板 71等 供应电力的装置。 蓄电池 20在箱体 10内部，配置在底座 12的前部、控制装置 70的下方位 置且逆变器 50的右侧。 蓄电池 20从上方用蓄电池固定皮带固定在倒 U形焊接板 12a上。
[0041] 发电机 40的外部设置有导风罩 40a，导风罩 40a的右侧固定有电子调速器 80，电 子调速器 80的上方设置有空气滤清器 31。
[0042] 电子调速器 80是调节控制发电机 40转速的装置。 电子调速器 80配置在上述发 电机 40外部的导风罩 40a右侧的中间部位焊接的一 ±夬焊接板上。
[0043] 本发明中的电子调速器 80配置在发动机 30的前方即发电机 40的外包装部件导 风罩 40a的右侧，扩大了电子调速器 80与高温区域之间的空间，减少了热量的传递。
[0044] 空气滤清器 31是将外部空气净化之后供给发动机 30的装置。 空气滤清器 31配 置在发动机 30的右前方，且位于发电机 40的上方附近，固定于发动机 30上方的缸头导风 板上，并通过进气管与发动机 30连接。
[0045] 发动机 30的后方设置有消音器 32，消音器 32的上方设置有燃油箱 60。
[0046] 消音器 32是消除发动机 30的排气音的装置。消音器 32配置在发动机 30的后方， 并通过排气管与发动机 30连接。 消音器 32外围设有排气风罩 17，使其仅与柴油数码发电 机 1后侧的空间连通。
[0047] 消音器 32的排气尾管 32a朝向后方，并一直延伸到箱体 10的尾部，即罩盖 11的 后侧板 l ie附近，在其延伸端部开口。 发动机 30产生的废气可以通过排气管，经由消音器 32，然后从排气尾管 32a排放到箱体 10的外部。
[0048] 燃油箱 60是储存供给发动机 30的燃油的装置。燃油箱 60配置在发动机 30的后 侧,固定在消音器 32外围的排气风罩 17上方。
[0049] 燃油滤清器 90是通过滤清器清除燃油中异物的装置。燃油滤清器 90设置在排气 风罩 17前侧焊接的一个 L型固定板上。
[0050] 本发明将蓄电池 20、逆变器 50、控制装置 70及其内部的电器元件分布于箱体 10 内部的前侧，被前隔板 16与其他装置隔开，电器元件下方的底座上设有冷却风进风口 13C, 从进风口 13C进入的冷却风进入冷却风道后被分成两部分，一部分冷却风进入位于上述前 隔板 16下部的圆形进风口被导风罩 40a内部的冷却风扇吸入发电机 40内部并冷却其中的 装置；另一部分冷却风通过蓄电池 20、逆变器 50以及控制装置 70等电器元件之间的间隙 后进入上述空气滤清器进气箱 19，并被上述空气滤清器 31吸入后进入发动机 30内部。 上 述冷却风在扫过位于其上方的蓄电池 20、逆变器 50以及控制装置 70等电器元件时带走大 量热量，使其表面温度降低，阻止上述电器元件由于温度过高而引起的非正常工作或寿命 降低等情况。 而且，可以防止上述电器元件因为高温而产生故障，降低了维护频率。
[0051] 另外，蓄电池 20、逆变器 50、以及控制装置 70等电器元件集中配置在箱体 10中前 隔板 16的前侧区域，极大地节省了维修空间,有利于箱体 10的小型化。
