    • A packaging and cooling system for one or more semi-conductor devices provides a casement defining a die chamber carrying a peripherally positioned power board with pre-attached multi-functional power pins communicating to medially positioned dies. The power pins provide not only improved power supply but also provide heat transfer from and mechanical support for the die. The die with an attached power supply plane and heat spreader is flip mounted on the power pins. The casement defines channels for coolant between the power board and dies and outwardly of the heat spreader. A closed cooling system provides a fluidic coolant to an input plenum from which it is sprayed into the die chamber channels for evaporative cooling therein on both sides of contained dies and about the power pins with subsequent recovery and recycling. The asymmetrical architecture within the die chamber allows less restricted thermal expansion of the various components than would result from common symmetrical architecture.
    • 用于一个或多个半导体器件的封装和冷却系统提供了一个定型模具腔室的平台,该模具室具有外围定位的电源板,其具有与内部定位的模具通信的预先连接的多功能电源插针。 电源引脚不仅提供改进的电源,还提供对模具的热传递和机械支撑。 具有附接电源平面和散热器的模具被翻转安装在电源引脚上。 隔板定义了电源板和模具之间的冷却剂通道,以及散热器外部的通道。 封闭的冷却系统向输入压力室提供流体冷却剂,从而将其喷射到模腔通道中,以便在容纳模具的两侧进行蒸发冷却,并且随后进行回收和再循环。 模具室内的不对称结构允许各种部件的热膨胀比普通对称结构产生的热膨胀较少。

    • A liquid fuel injection device for internal combustion engines provides an elongate peripheral injector housing defining a cylindrical medial chamber with a fluid plenum having a fluid inlet at a first end and plural fluid exit ports at a second end that is carried within a combustion chamber of an engine cylinder. The plural exit ports are spacedly arrayed in both circumferential and axial directions and may be angularly oriented in the injector housing. The medial chamber of the injector housing rotatably carries an atomizer casement defining an internal chamber with plural circumferentially spaced inlet orifices at a first end which communicates with the fluid plenum of the first end of the injector housing and plural spray orifices at the second end. Each spray orifice of the atomizer casement carries a pressure swirl atomizer with output orifice arrayed to communicate with at least one of the exit ports defined in the second end of the injector housing at at least one rotary position of the atomizer casement relative to the injector housing. A first species of injection device provides electrically powered mechanism for rotating the atomizer casement relative to the injector housing and a second species provides pressurized fuel powered mechanism for such rotation. Both species allow adjustment of fuel injection timing and flow rate independently of each other.

    • An EMI shielding fluid control shroud is adapted for use in spray cooling EMI producing or EMI sensitive components. The EMI shielding shroud, carried between a printed circuit board and a spray plate, defines an interior spray cavity which prevents interference with coolant spray directed at one or more heat-generating, EMI producing or sensitive components, such as integrated circuits. The size and shape of the shroud provide control over the flow and direction of the coolant spray and result in better cooling of the components carried on the printed circuit board and partially enclosed by the shroud. The shroud provides an EMI shield which prevents passage by EMI in either direction, while allowing coolant fluid to exit through the EMI shielding material.
    • EMI屏蔽液体控制罩适用于喷雾冷却EMI产生或EMI敏感元件。 携带在印刷电路板和喷射板之间的EMI屏蔽罩限定了内部喷射腔,其防止干扰针对一个或多个发热,EMI产生或敏感部件(例如集成电路)的冷却剂喷射。 护罩的尺寸和形状可以控制冷却剂喷射的流动和方向,并且可以更好地冷却承载在印刷电路板上并部分地被护罩封闭的部件。 护罩提供EMI屏蔽,防止EMI在任一方向上通过,同时允许冷却剂流体通过EMI屏蔽材料排出。
