    • A heat transfer system in which a fluid of substantial heat absorption qualities is caused to flow in successive heat absorption and heat dissipation phases, a latter having one or more differential modes. In the disclosed embodiment of the system, a cold plate-liquid boiler assembly provides flow paths for the successive phases, the differential heat dissipation modes being provided by the liquid boiler and by external cooling means alternatively included in a heat rejection circuit. Vent control apparatus associated with the liquid boiler tends to maintain a pressure therein conducive of boiling at selected temperature values.
    • 一种传热系统,其中具有相当的吸热性质的流体在连续的吸热和散热相中流动,后者具有一个或多个差分模式。 在所公开的系统的实施例中,冷板 - 液体锅炉组件为连续相提供流动路径,差动散热模式由液体锅炉提供,并且外部冷却装置备选地包括在排热回路中。 与液体锅炉相关联的排气控制装置倾向于在其中保持有利于在选定温度值下沸腾的压力。

    • A heat transfer device, defined here as a heat link, having a capillary vaporizer adjacent a heat source, transfers heat to a heat sink by vaporization and condensation of a heat transfer fluid within the device. A first passage is provided for conveying vapor from the capillary vaporizer to the heat sink. Another passage which is essentially a continuation of the first passage, conveys condensed liquid from the heat sink to the vaporizer, thus allowing the distance that the liquid must flow through capillary material to be quite short. Contact of the returning liquid with the surface of the vaporizer is assured by providing means for maintaining the temperature of the liquid in the return line at a sufficiently low temperature that any vapor will condense; or, alternatively, by having means for extracting any vapor formed in the returning liquid. In this manner, the heat link operates with high heat flux without any substantial resistance to liquid flow through a long capillary flow path. By thus replacing almost all of the liquid return wick, with its high resistance to fluid flow, of heat pipes with a low flow resistance liquid passage or conduit, the heat flux capacity of the heat link is greatly increased over that of the heat pipe while the quantity of porous material used and the heat link weight are considerably reduced so that a heat link typically has 10 to 1,000 times the heat flux capacity of a heat pipe having the same weight. ''''Boosted'''' embodiments of the heat link employing additional means for circulating the fluid, such as vapor jet pumps, powered at least in part by vapor from the capillary vaporizer, are also described. Some ''''boosted'''' heat links are capable of handling heat fluxes in the multi-megawatt range while having no moving parts except for check valves and the fluid itself.
    • 传热装置(这里定义为热连接),具有邻近热源的毛细管蒸发器,通过装置内的传热流体的蒸发和冷凝将热传递到散热器。 第一通道被提供用于将蒸气从毛细管蒸发器输送到散热器。 基本上是第一通道的延续的另一通道将冷凝的液体从散热器传送到蒸发器,从而允许液体必须流过毛细管材料的距离相当短。 返回液体与蒸发器表面的接触通过提供用于将回流管中的液体的温度保持在足够低的温度以使任何蒸气冷凝的方式来确保; 或者,通过具有用于提取形成在返回液体中的蒸气的装置。 以这种方式,热连接器以高热通量运行,而不会对通过长毛细管流动路径的液体流动产生实质的阻力。 通过这样替换几乎所有的具有高阻力流体流动的液体返回灯芯,具有低流阻液体通道或管道的热管,热链的热通量大大高于热管的热通量,而 使用的多孔材料的数量和热连接重量大大减少,使得热连接通常具有具有相同重量的热管的热通量的10至1,000倍。 还描述了使用附加装置循环流体的“增强”实施例,例如蒸气喷射泵,其至少部分地由毛细管蒸发器的蒸气供电。 一些“升压”热连接能够处理多兆瓦范围内的热通量,除了止回阀和流体本身之外没有移动部件。
