摘要：
A heat exchanger (100, Fig.1) comprising a plurality of first fluid channels (10, 30, 50, 70) a plurality of conduits (8) for interconnecting the first fluid channels, a plurality of second fluid channels (20, 40, 60) and a plurality of conduits (9) for interconnecting the second fluid channels. The heat exchanger is configured as a plurality of repeating units R, each repeating unit comprising a base plate 216 having a first opening 218a, and a first conduit 208a of the conduits extending from the plate, the shape of the opening corresponding to the shape of the conduit. The repeating units may be arranged as a matrix, where units repeat in first and second mutually orthogonal directions X, Z, and each repeating unit is contiguous with neighbouring units in the plane defined by the first and second mutually orthogonal directions, such that base plates are coplanar. The units may also repeat in a third direction Y mutually orthogonal to the first and second directions, where each repeating unit is contiguous with neighbouring units such that the conduit from a first neighbouring unit connects to the first opening and the conduit connects to an opening of a second neighbouring unit.
