发动机 2下方的底座 8上设置有第三进风口 13。 如图 8所示, 第三进风口 13包括前第三进风口 13A、 中第三进风口 13B及后第三进风口 13C。 前第三进 风口 13A与导风部件 25的位置相对应,中第三进风口 13B与发电机 3的位置相 对应, 后第三进风口 13C与冷却风扇 17的位置相对应。 前第三进风口 13A、 中 第三进风口 13B及后第三进风口 13C分别由呈矩阵排列的开口构成。
发动机 2的右前上方设置有逆变器 4。逆变器 4整流发电机 3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 4配置在箱体 5的右侧面, 即 罩盖 9的右侧板%的前侧附近。 逆变器 4与罩盖 9的右侧板 9b之间设有固定 部件。
如图 3、 图 5、 图 6及图 7所示, 逆变器 4右方的罩盖 9上, 即右侧板 9b 上设置有第一进风口 12A及第二进风口 12B。 第一进风口 12A与逆变器 4的位 置相对应, 配置在右侧板 9b的前上侧, 由呈矩阵排列的开口部 12a构成。 第二 进风口 12B位于第一进风口 12A的下方,配置在右侧板 9b的前下侧, 由呈矩阵 排列的开口部 12b构成。
如图 2、 图 5、 图 6及图 7所示, 逆变器 4的外面设置有密封盒 23, 密封盒 23与空气滤清器 16的进气管相连通。
罩盖 9的内侧与第二进风口 12B相对应处设置有导风部件 25,导风部件 25 的上方设置有通风口, 与箱体 5的内部相连通。 导风部件 25内设置有导风板, 内部呈 S形结构。
导风部件 25 的左右以及上下幅度比第二进风口 12B 的左右以及上下幅度 大, 由导风部件 25从后方覆盖第二进风口 12B。
再参见图 2, 发动机 2的右方设置有蓄电池 24。 蓄电池 24是给用于起动发 动机 2的起动装置、 逆变器 4的控制部及控制面板等供应电力的装置。
以上结构的柴油数码发电机 1, 在其箱体 5的内部形成三个冷却风道。 由第 一进风口 12A和空气滤清器 16、发动机 2、消音器 18之间形成沿前后方向延伸 的冷却风道为第一风道 31 ;在第二进风口 12B和排风口 14之间形成的沿前后方 向延伸的冷却风道为第二风道 32; 由第三进风口 13与排风口 14之间形成的沿 上下方向延伸的冷却风道为第三风道。
本发明在上述冷却风道的前后中途部设置发动机 2。将发动机 1的前方空间 设为冷却风道的上流侧, 发动机 2后方空间设为冷却风道的下流侧。 在冷却风 道上流侧以包围发动机 2的状态配置发电机 3、 逆变器 4以及空气滤清器 16, 在冷却风道的下流侧配置散热器 6及消音器 18。
本发明的冷却过程如下: 见图 2, 当发动机 2驱动冷却风扇 17旋转的时候, 作为冷却风的外部空气从第一进风口 12A和第二进风口 12B以及第三进风口 13 进入箱体 5的内部。
从第一进风口 12A进入的冷却风首先流向位于第一风道 31上流侧的逆变器 4, 然后经过第一风道 31进入空气滤清器 16、 发动机 2、 消音器 18等设备, 如 图 2、 图 6及图 7中箭头所示。
从第二进风口 12B进入的冷却风通过第二风道 32, 冷却风沿着 S型通道向 上方流动, 首先被导向位于冷却风道上流侧的空气滤清器 16和发电机 3, 经由 发动机 1和排气管 21等周边流向位于冷却风道上的散热器 6等, 最后从排风口 14排放到箱体 5的外部, 如图 2、 图 6及图 7中箭头所示。
从第三进风口 13进入的冷却风通过第三风道, 经由发动机 2和排气管 21 等周边流向位于冷却风道上的散热器 6等, 最后从排风口 14排放到箱体 5的外 部。
本发明具有以下优点: ,
1、 本发明根据箱体 5内各装置的冷却需要配置, 在冷却风道的中途设置发 动机 2, 在冷却风道的上流侧配置发电机 3、 逆变器 4以及空气滤清器 16, 在冷 却风道的下流侧配置散热器 6及消音器 18; 特别需要冷却的逆变器 4和空气滤 清器 16可以由温度较低的冷却风进行冷却, 提高了冷却风的冷却效果。 另外, 其他装置以包围发动机 2 的状态配置, 可以紧凑化配置其他装置, 同时还能充 当隔音壁, 降低发动机 2的噪音。
2、 第一进风口 12A内侧设有将逆变器 4密封的密封盒 23, 使第一风道 31 具有管道结构, 可以降低从第一进风口 12A向箱体 5外部泄漏噪音。
3、第二进风口 12B的内侧设置有导风部件 25,可以降低从第二进风口 12B 向箱体 5外部泄漏的噪音。
4、 从第三进风口 13进入第三风道的冷却风与从第二进风口 12B进入的冷 却风可以均衡冷却各装置, 降低冷却风冷却效果的偏差。
