    • Heat transfer fins (110), and heat exchangers (100) incorporating such fins (110), enhancing heat transfer with acceptable pressure drop increase. The fins (110) include tabs or secondary fins bent upward and downward from the fin body at a selected bend angle. All or a majority of the tabs are aligned with a simple flow path or with local flow paths for cooling air adjacent the fins (110) to minimize turbulence and pressure drop. The tabs are planar and generally aligned parallel to the simple flow path or local flow paths and are arranged so as to serve as a plurality of sites for starting new boundary layers by offsetting the tabs such that downstream tabs are not shadowed by upstream tabs. The tabs have a height sufficiently large to extend the tabs out into boundary layers on the fin (110). The tabs provide more uniform flow over fins (110) and shrink wake size behind tubes (120).
    • 传热翅片(110)和包含这种翅片(110)的热交换器(100),增强了可接受的压降增加的热传递。 散热片(110)包括以翅片本体以选定的弯曲角度向上和向下弯曲的凸片或二次散热片。 所有或大部分翼片与简单的流动路径对准,或者与用于冷却与翅片(110)相邻的冷却空气的局部流动路线对齐,以最小化湍流和压降。 突片是平面的并且大致对齐于平行于简单流动路径或局部流动路径,并且被布置成用作多个位置,用于通过偏移突起来启动新的边界层,使得下游突出部不被上游突出部遮蔽。 突片具有足够大的高度,以将突出部延伸到翅片(110)上的边界层中。 翼片提供在鳍(110)上更均匀的流动并且在管(120)后面收缩尾巴尺寸。

    • A power generating system (110) comprising a heat source (116) and an incremental vapor generator system (112) operatively associated with the heat source (116). The incremental vapor generator system (112) includes a first heating section (136) and a second heating section (138). The first heating section (136) receives a mixed working fluid (114) and generates a first heated working fluid stream comprising a vapor portion (120) and a liquid portion. The second heating section (138) is operatively associated with the first heating section (136) and receives the liquid portion from the first heated working fluid stream. The second heating section (138) generates a second heated working fluid system stream comprising a vapor portion (122). An energy conversion device (126) operatively associated with the incremental vapor generator system (112) converts into useful work heat energy contained in the vapor portion (120, 122) of the first and second heated working fluid streams.
    • 一种发电系统(110),包括热源(116)和可操作地与热源(116)关联的增量蒸汽发生器系统(112)。 增量式蒸气发生器系统(112)包括第一加热部分(136)和第二加热部分(138)。 第一加热部分(136)接收混合的工作流体(114)并且产生包括蒸气部分(120)和液体部分的第一加热的工作流体流。 第二加热部分(138)与第一加热部分(136)可操作地相关联并从第一加热的工作流体流接收液体部分。 第二加热部分(138)产生包括蒸汽部分(122)的第二加热的工作流体系统流。 与增量式蒸汽发生器系统(112)可操作地相关联的能量转换装置(126)转换成包含在第一和第二加热的工作流体流的蒸汽部分(120,122)中的有用功的热能。
