    • A heat exchanger element comprises an outer tube (11), an inner tube (12) within the outer tube and a first fluid flow path for a first heat exchange fluid formed between the inner and outer tubes. A second heat exchange fluid is in heat transfer relation to the outer surface of the outer tube and/or the inner surface of the inner tube. A sleeve (13) is provided within the first fluid flow path between the inner and outer tubes. The sleeve defines an outer interface (16) with the inner surface of the outer tube and an inner interface (14) with the outer surface of the inner tube. Generally longitudinal grooves (16, 17) are provided at each interface to provide together the first fluid flow path.
    • 热交换器元件包括外管(11),外管内的内管(12)和形成在内管和外管之间的第一热交换流体的第一流体流路。 第二热交换流体与外管的外表面和/或内管的内表面传热关系。 套筒(13)设置在内管和外管之间的第一流体流动路径内。 套管限定了外部接口(16)与外管的内表面和内接口(14)与内管的外表面。 通常在每个界面处设置纵向凹槽(16,17)以将第一流体流动路径提供在一起。
