Heat exchanger comprising a plurality of laminates

摘要

A heat exchanger 10 is comprised of a plurality of laminates 11 coupled together to permit first €˜F1 €™ and second €˜F2 €™ fluids to flow in a thermal transfer arrangement. Each of the laminates comprises primary heat transfer walls defining first flow-paths 50 along which the first fluid flows and secondary heat transfer walls 40 defining second flow-paths 60 along which the second fluid flows. In use, the primary walls contact the first and second fluid and the secondary walls contact the second fluid. At least one of the primary walls is corrugated along a length of at least one of the first flow pathways. Preferably, all of the primary walls are corrugated. The corrugation may be smooth or angular. The flow-paths may be oriented such that the first and second fluids flow transversely to one another. The heat exchanger is particularly suited to production by Direct Metal Laser Sintering (DMLS).
