FIELD: power engineering.SUBSTANCE: claimed heat exchanger (12) comprises pairs of plates (29) laid one above the other to make the pile. Note here that the first flow space for first fluid flow passage and second flow space (21) for second fluid flow passage are composed between both plates (30, 31) of one pair of plates (29). Note here that said second flow space (21) for second fluid flow passage is composed between two adjacent pairs of plates (29). Besides, there are the first fluid flow inlet (32) and first fluid flow discharge outlet (33). Plates (30, 31) have at least one long hole, particularly, one long slit hole to reduce strains in said plates (30, 31).EFFECT: higher resistance to high thermal and mechanical loads, longer life.6 cl, 6 dwg |
