    • PROBLEM TO BE SOLVED: To provide a water supply pipe for a steam generator, capable of suppressing thermal stratification inside a pipe.SOLUTION: A water supply pipe for a steam generator includes: an insertion pipe 21 inserted to a through-hole 112 of an outer shell member; and an in-generator pipe 22 connected to the insertion pipe. The in-generator pipe includes: a duct; and an outflow part 25 for allowing cooling water inside the duct to flow out to a space 40 in the steam generator. The duct includes: a first inclination part 24c where not a side close to the insertion pipe but a side far from the insertion pipe in a flow direction is positioned on an upper side in a vertical direction; and a second inclination part that is positioned to be farther from the insertion pipe than the first inclination part and where not a side close to the insertion pipe but a side farther from the insertion pipe in a flow direction is positioned on a lower side in a vertical direction. In at least a partial section in a flow direction in a duct 234a between the first inclination part and the second inclination part, a lower end 234b of a cross section of the duct is positioned to be upper in a vertical direction than a horizontal surface 30 passing an upper end 21a of an inner wall surface of the insertion pipe in a connection part between the insertion pipe and the in-generator pipe.
    • 要解决的问题:提供一种能够抑制管内热分层的蒸汽发生器供水管。解决方案:一种用于蒸汽发生器的供水管,包括:插入管道21的通孔112, 外壳构件; 以及与插入管连接的发电机管22。 发电机管道包括:管道; 以及用于允许管道内的冷却水流出到蒸汽发生器中的空间40的流出部分25。 导管包括:第一倾斜部分24c,其中不是靠近插入管的一侧,而是在流动方向上远离插入管的一侧位于垂直方向上的上侧; 以及第二倾斜部,其被定位成比所述第一倾斜部更远离所述插入管,并且其中不是靠近所述插入管的一侧,而是沿着流动方向离所述插入管更远的一侧位于所述第一倾斜部的下侧 垂直方向 在第一倾斜部和第二倾斜部之间的管道234a中的流动方向的至少一部分截面中,管道的横截面的下端234b位于比水平面30的垂直方向上方 将插管的内壁面的上端21a通过插入管和发生器管之间的连接部。

    • PROBLEM TO BE SOLVED: To provide a heat exchanger having a plurality of flat tubes connected between two header/collector tubes, in which heat transfer between among flat tubes is suppressed.SOLUTION: An upper heat exchange region 51 is divided into a plurality of principal heat exchange sections 51a to 51c, while a lower heat exchange region 52 is divided into a plurality of auxiliary heat exchange sections 52a to 52c. A first header tube 60 is partitioned correpondingly to the upper heat exchange region 51 and to the lower heat exchange region 52, and a lower space 62 is further partitioned into communication spaces 62a to 62c corresponding to the auxiliary heat exchange sections 52a to 52c. A second header tube 70 is partitioned into: a communication space 71c jointly corresponding to both of the principal heat exchange section 51a in the lowest position in the upper heat exchange region 51 and the auxiliary heat exchange section 52c in the highest position in the lower heat exchange region 52; and communication spaces 71a, 71b, 71d, 71e corresponding to the rest of the principal heat exchange sections 51b, 51c and the auxiliary heat exchange sections 52a, 52b respectively. The communication spaces 71a and 71d are connected by a communication tube 72, while the communication spaces 71b and 71e are connected by a communication tube 73.
    • 要解决的问题:提供一种热交换器,其具有连接在两个集管之间的多个扁平管,其中扁平管之间的热传递被抑制。 解决方案:上部热交换区域51被分成多个主要热交换部分51a至51c,而下部热交换区域52被分成多个辅助热交换部分52a至52c。 第一集管60相应地分隔到上部热交换区域51和下部热交换区域52,并且下部空间62被进一步分隔成与辅助热交换部分52a至52c相对应的通信空间62a至62c。 第二集管70被分割为:与上部热交换区域51中的最低位置的主要热交换部51a和辅助热交换部52c的两者中的低热的最高位置共同对应的连通空间71c 交换区域52; 以及分别对应于其余主要热交换部分51b,51c和辅助热交换部分52a,52b的连通空间71a,71b,71d,71e。 通信空间71a和71d通过连通管72连接,通信空间71b和71e通过连通管73连接。版权所有(C)2012,JPO&INPIT
