An apparatus for exchanging heat between at least three fluids includes an elongate sealed chamber having at least two separate plate cores arranged inside the sealed chamber and means for supporting each of the plate cores inside the scaled chamber. Each of the plate cores are provided with circuits for two separate fluids, fluid inlet and outlet means for the respective circuits of the plate cores, and connecting means enabling fluid circulation between the plate cores.
