The invention solves the problem of construction of the side walls of the heat exchanger, which is characterised by the fact that the external edges of the lamel plates ( 1 ) are formed as an inseparably overlapping angle, and creates a leaktight external surface for the side walls of the combustion chamber ( 2 ). Inside the side walls of the combustion chamber ( 2 ) there are flow channels ( 3 ) for the heated medium.
