    • A heat exchanger having an intermediate heating medium has a shell of the heat exchanger, a plurality of cylindrical partition tubes each of which has an annular space therein and is closed at both end portions thereof with annular walls, the cylindrical partition tubes being arranged concentrically in a mutually spaced manner in the shell, and helical coil-shaped heat exchanger tubes each of which is disposed in the annular space in the cylindrical partition tube. A high-temperature heating medium flows in the shell through clearances among the helically arranged multiple cylindrical partition tubes, a low-temperature heating medium flows in each of the helical coil-shaped heat exchanger tubes, and an intermediate heating medium chemically inactive with respect to both the high-temperature heating medium and the low-temperature heating medium and excellent in the heat transferring performance is passed through each of the annular spaces in the cylindrical partition tubes.
    • 具有中间加热介质的热交换器具有热交换器的外壳,多个圆筒形分隔管,每个分隔管在其中具有环形空间并且在其两个端部处与环形壁封闭,所述圆筒形分隔管同心地布置在 壳体中相互间隔的方式,以及每个都设置在圆筒形分隔管的环形空间中的螺旋形的线圈状的热交换器管。 高温加热介质通过螺旋排列的多个圆柱形分隔管之间的间隙在壳体中流动,低温加热介质流入每个螺旋形卷状热交换器管中,并且相对于 高温加热介质和低温加热介质均具有良好的传热性能,通过圆筒形分隔管中的每个环形空间。
