A heat exchanger has a number of corrugated plates arranged one above the other with spaces between them. The two fluids between which heat is to be exchanged flow in counter-flow relationship in alternate spaces between the plates. The plates are arranged so that the flow passages between them are of constant width across the whole flow-section of the heat exchanger, and spacers are mounted on some of the corrugations to maintain the plates the correct distance apart.
