<p>A heat exchanger comprising heat delivery surfaces (1a) and flow channels (6, 7, 10, 11) with inlets and outlets (8, 9, 12, 13) for the primary and secondary flows. The heat delivery surfaces are formed into at least one heat transfer unit (1) consisting of corrugated plate components (1a) joined together tightly, in which there are connecting orifices (4, 5) for the primary flow, which orifices form two flow channels (6, 7) in the longitudinal direction of the heat exchanger for the primary flow; every second space between plates of the unit (1) comprising transverse flow channels (10) for the primary flow, and on the other hand, open spaces between plates next to said spaces between plates forming transverse flow channels (11) for the secondary flow; the heat transfer unit (1) being further surrounded by a casing (2) with an inlet (12) and an outlet (13) for the secondary flow, the casing being shut at its both ends by end plats (3), at least one of which has an inlet (8) and an outlet (9) for the primary flow.</p> |
