The method comprises stacking essentially identical corrugated heat transfer plates 1 so they cover one another, and connecting the interspaces between the plates at their edges to inlet and outlet lines 5, 6, 7, 8 for the media which are involved in the heat transfer so that a flow of a heat-emitting medium is guided through every other interspace between the plates and a flow of a heat-absorbing medium is guided through every other interspace between the plates. It is essential that the flow pressure losses and heat transfer coefficient in the heat exchanger are determined by stacking the heat transfer plates on one another in such a manner that the grooves 11, 12 in different plates are arranged at a selected angle to one another. To make this possible, use is made of essentially circular heat transfer plates 1 or regular polygonal heat transfer plates, in which the direction of the grooves is such that the grooves in plates stacked on one another can intersect selectively at at least two different angles to one another. <IMAGE>
