Description

一种静音发电机组的底盘总成结构 技术领域
[0001 ] 本发明涉及一种静音发电机组的底盘总成结构，具体地说是聚 ¾进气式内燃发电 机组的底盘,属于空气循环的通风技术领域。 背景技术
[0002] 传统的封闭式内燃发电机组的底^:通常把进气口分散布置在底盘的各个方位，有 些布置在底盘的底部，有些布置在底盘的周边。这种分散布置，常常会因为进气的方向不同 使气流之间相互千扰甚至对撞，消耗了气流自身的动能，不能充分地对发电机组内部需要 散热的部件进行冷却。对于发热量大的电子元件,采用独立的电子风扇对其进行散热，由于 发电机组内部环境使得电子风扇的寿命不稳定，往往都需要定期检修、更换。 此外,传统的 发电机组大量采用槽钢、角钢等型材,导致底盘过于笨重。 发明内容
[0003] 本发明的目的是克服现有技术中存在的不足，提供一种结构简单、紧凑、合理的静 音发电机组的底盘总成结构。
[0004] 按照本发明提供的技术方案，一种静音发电机组的底盘总成结构， β括底盘、设在 底盘两侧的左侧封板和右侧封板,特征是：在所述底盘一端的两侧设置 ah格栅,从进气格 栅向内是水平布置的两个聚流室，聚流室与进气格栅相对的另一端设有封板；在聚流室的 内侧面设有相向的气流出口，所述气流出口设置在与进气格栅相对的 一端；在聚流室的 上端面开有矩形的开槽，在开槽的下方设有气流导向板。
C0005] 在所述开槽的边缘上设有电子元件固定孔。
[0006] 在所述聚流室中部的上端面设有内燃机固定孔。
[0007] 在内燃机固定孔的正下方设置支撑立柱和加强板。
[0008] 在所述两个聚流室的内侧壁之间形成空腔。
[0009] 本发明结构简单、紧凑、合理；由于底盘采用聚流进气方式，便冷却气流从发电机 组的一端进入底盘，具有较高的流速和动能,气流导向板减小气流通道截面积，使气流流速 加快通过安装在聚流室开槽的电子元件散热器，快速带走电子元件的热量，增大冷却气流 与电子元件的换热率，取得良好的冷却效果，有效地隔断发电机组内部噪音向外辐射的途 径，降低噪音污染；加大内燃机安装孔水平方向间距及减小内燃机安装孔与内燃机重心的 垂直方向距离可以有效减小内燃机振动对发电机组的影响。 附图说明
[0010] 图 1是本发明的底盘结构示意图。
[0011 ] 图 2是本发明的底盘安装电子元件后的结构示意图。
[0012] 图 3是图 2的 A- A剖视图。
[0013] 图 4是本发明的底盘安装发电机、内燃机、电子元件后的分解状态示意图。 [0014] 图 5是本发明的底盘安装发电机、内燃机、电子元件后的结构 意图。
[0015] 图 6是本发明使用在发电机组内部整体冷却结构状态图。 ' 具体实施方式
