根据图1和2所示的示例性实施方式，系统10可包括壳体20，其被构造成用于给系统10的不同部件提供保护和/或可运输性。例如壳体20可包括壁，例如，相对的侧壁22、前壁24和一个或多个后门26、底板28和顶壁30，从而限定壳体20的外部空间并且还可能限定内部空间。根据一些实施方式，系统10可包括一个或多个装置32，其被构造成便于系统10在需要提供电能的地点之间的运输。例如，图1中示出的示例性实施方式包括多个车轮，便于系统10通过车辆、例如卡车或牵引车(例如，壳体20为至少类似于拖车的形式，以与牵引车拖车设备的拖车相似的方式被拖动)的牵引。其它形式的本领域已知的装置32(例如，用于沿着铁路轨道、浮桥、和/或滑道行驶的履带、车轮)也是可以想到的。如此处更详细说明的，壳体20的一些实施方式可限定位于壳体20的外部和壳体20的内部之间的一个或多个通路。
根据一些实施方式，系统10可包括位于壳体20内部的存储箱34(例如，油箱)，用于给发动机12供应燃料。存储箱34可通过一条或多条燃料管路(未示出)连接到发动机12上。根据一些实施方式，存储箱34位于壳体20的外部，且/或燃料通过外部源，例如，用于供应如汽油、柴油、天然气、氢气、乙醇、甲醇和/或它们的任何组合的燃料的管道提供。
根据一些实施方式，系统10可包括冷却系统36，其被构造成用于调节发动机12和/或电机14的温度。例如，冷却系统36可包括：一个或多个热交换器38，例如可操作地连接到发动机12的一个或多个空气-空气后冷却器(ATAAC)；和/或一个或多个散热器40，例如，可操作的连接到发动机12上的水套散热器。根据一些实施方式，发动机12可包括一个或多个涡轮增压器(未示出)，热交换器38可操作地连接到一个或多个涡轮增压器，以冷却进入涡轮增压器的空气。系统10可包括一个或多个例如位于发动机12和热交换器38之间的风扇41。风扇41可操作地通过传动带(未示出)连接到发动机12上，和/或通过电动机(未示出)被驱动，并可提供流到和/或穿过热交换器38的空气流，以提供冷却空气给热交换器38。
示例性的散热器40可被构造成接收和冷却冷却剂(例如冷却液)流，该冷却剂可通过冷却管路(未示出)循环进入和/或穿过发动机12，从而冷却发动机12。一个或多个风扇42可与散热器40相连，并被构造成给散热器40提供冷却空气流。风扇42可例如通过电动机(未示出)被驱动，该电动机可通过例如皮带传动装置(未示出)连接到而风扇42。
根据一些实施方式，如图1和2所示，壳体20可包括位于热交换器38和散热器40之间的隔板43。壳体20的一个或多个侧壁22可包括空气通路45(例如放气孔(见图3))，用于允许空气进入和/或流出壳体20。另外，壳体20的顶壁30可限定位于热交换器38和/或散热器40附近(如邻近)的一个或多个开口50。根据一些实施方式，与热交换器38相连的风扇41可用于通过通路45在A处将空气引入壳体20，并在B处穿过热交换器38(参见图2和图3)。在流动穿过热交换器38时空气经隔板43转向，并在C处通过顶壁30中的开口50。
根据一些实施方式，风扇30可被构造成通过壳体20的开放端，例如，通过打开D处的一个或多个后门26(或通过后门26中的开口(未示出))，将空气引入并穿过散热器40，然后空气经隔板43转向并在E处通过顶壁38中的开口50流出。
根据本发明的一些实施方式，发动机12可包括排气系统44(参见图1和2)，用于除去壳体20内的热量和/或燃烧产物。例如，排气系统44可包括在顶壁处安装的消声器46，该消声器46与发动机12流体连通。排气系统44还可包括位于消声器46下游的一个或多个延伸部分48，该延伸部分48用于提供废气从发动机12通过消声器46到壳体20外部的流动通道。例如如图1所示，延伸部分48可在热交换器38上方从消声器46延伸到顶壁30中的一个或多个开口50，使得废气通过开口50排出。
根据一些实施方式，例如如图2所示，系统10可包括接口52，便于控制和/或监测系统10。例如，接口52可包括电子连接器，该电子连接器便于控制器18和位于壳体20外部的系统之间的电连接，这些外部系统利于例如发电系统之间的均分负载、岸电的供应(例如蓄电池充电器和/或与系统10相连的控制系统的电能)、和/或监控系统10的状态。
如图4和图5所示，根据一些实施方式，系统10可包括一个或多个板54，用于屏蔽与发动机12的运行相关的热能(例如热量)。例如，板54可操作地连接到发动机12的相对侧，用于回转和/或反射发动机12的热量。例如，板54可操作地通过托架或直接连接到发动机12上。例如，板54可操作地连接到发动机12的发动机气缸体55、进气通路57(例如进气口或歧管)和/或排气通路(例如排气歧管，未示出)。
如图6所示，板54具有长度尺寸L和宽度尺寸W。长度尺寸L和宽度尺寸W取决于例如与发动机12相关的长度尺寸和/或高度尺寸。例如板54的长度尺寸L基本上对应于发动机气缸体55的长度尺寸，或发动机12的气缸盖(未显示)的长度尺寸。宽度W基本上对应于发动机12的例如从气缸盖的下边缘直到进气通路57之间的高度尺寸。替代的，长度尺寸L和/或宽度尺寸W可以更长或更短，例如宽度W可选择为板54从发动机气缸体55的下边缘延伸到气缸盖的上边缘，或甚至延伸到进气通路57的下边缘。根据一些实施方式，板54(例如，板54包括位于发动机12相对侧的两块板，如图4所示)可具有不同的尺寸和/或结构。
根据一些实施方式，板54可由钢板或任何其它合适的材料制成。例如板54可由一层厚度范围从约10gage到约20gage、例如约14gage到约16gage的材料制成。根据一些实施方式，板54可包括用于增强其刚度的结构和/或部分，例如用来减少振动和/或噪音。例如，如图6所示，示例性的板54包括沿着板54的上边缘58延伸的凸缘56。板54还可包括沿着板54的下边缘62延伸的凸缘60。凸缘56和/或60可以和板54一体地形成，或单独制成并通过焊接和/或紧固件(例如螺钉、螺栓和/或铆钉)与板54可操作地连接在一起。凸缘56和60可从板54的任一方向延伸出，例如沿相同或相反方向延伸。板54还限定结构64(即相对于板54限定基本为矩形的形状)，例如边缘结构和/或从板54内部切掉的部分。例如如图6所示，板54限定在附图标记64处通过将其一个角去掉而形成的三角形形状的边缘结构。结构64可限定任意直线和/或曲线形状并提供用于系统10的部件，例如与发动机12相连的部件的空隙。
根据一些实施方式(参见图4和5)，热隔离件66可围绕与热交换器38和/或散热器40相连的管件设置。例如，热隔离件66可包括任何隔离衬垫材料，如具有织物和/或非织织物及覆盖层的衬垫(例如，具有硅覆盖层的尼龙衬垫)。示例性的隔离件66用于防止热量在例如与热交换器38和/或散热器40相连的管件和壳体20的内部之间交换。这可使冷却空气例如从示例性的空气通路45流向热交换器38时通过的壳体20的部分中的空气的温度降低。
如图3所示，例如，与热交换器38相连的风扇41可用于使空气经通路45在A处吸入壳体20并进入壳体20内部的区域68。区域68用于包围例如发动机12和/或电机14。风扇41可在B处从区域68抽吸空气通过热交换器38。在流过热交换器38时，空气经隔板43转向并在C处通过顶壁30中的开口50。
工业实用性
示例性的系统10可用于在不能从公共电网获得电力的场合、例如偏远地区和/或正在停电的区域进行发电。示例性的系统10中的一个或多个发动机12可用于输出机械能，并且一个或多个电机14可用来将机械能转化为电能。一个或多个控制面板18被构造成便于控制发动机12和电机14中的至少一个。壳体20可用于容纳发动机12和电机14中的至少一个。
系统10可设有一个或多个板54，其可用于隔离与发动机12的运转相关的热能(例如，热量)。例如，板54可操作地连接到发动机12的相对侧，并用来回转和/或反射发动机12的热量(例如辐射然)。根据一些实施方式，板54可用于在发动机运转过程中隔离发动机12的热量，并且在空气流经热交换器38之前流经区域68时减少这种热量对空气温度增加的影响。这可用于提高了热交换器38冷却进入到与发动机12相连的一个或多个进气通路(或涡轮增压器)内的空气的效率。这又增加了发动机12的效率和/或减少发动机运行时产生的排放。根据一些实施方式，热隔离件66可具有至少类似功能。
对本领域技术人员来说，对公开的发电系统进行修正和改变是可以想到的。对本领域技术人员来说，考虑过对示例性公开的系统和方法的说明和实施之后，其它的实施方式也是可以想到的。这里的说明和实施例仅作示例之用。
