A heat exchanger comprises a plurality of plates (7, 9, 11, 13) each having first (15, 19) and second (17, 21) heat transfer surfaces on reverse sides. The plates are arranged in a stack with spacings between mutually facing heat transfer surfaces of adjacent plates. Alternate spacings in the stack providing respectively, a first fluid path (51, 52) for a first fluid and a second fluid path (57, 59) for a second fluid. The plates are arranged in a plurality of groups, each comprising at least two plates. Pin means are provided in the form of a plurality of groups of pins (23).
