This present invention describes a novel type of internal exchanger intended to carry out Fischer-Tropsch synthesis. This exchanger has a modular design and comprises a central tube with partitions allowing at the same time the supply of coolant to the hairpins of the module and the recovery of the partially vaporized fluid from these same hairpins.
