A heat exchanger has a central carrier tube 1 which supports a partially-finned heat exchange tube by means of retaining devices 2 and 3. The heat exchange tube has a plurality of straight tubes 42 provided with axially-extending fins 6, the finned tubes being interconnected by tubular connectors 4. Each tubular connector 4 has a V-shaped portion which extends substantially at right-angles to straight portions 41 which are contiguous with the ends of the V- shaped portion. The straight portions 41 of a given tubular connector 4 are connected to the adjacent ends of a respective pair of finned tubes 42. The V-shaped portions of the tubular connectors are clamped to the retaining devices 2 and 3. The finned tubes 42 are symmetrically disposed about the central carrier tube 1, so that they form together with the tubular connectors 4 a self-supporting tubular cage. <IMAGE> |
