Abstract
Indirect heat exchanger, of the type comprising a series of parallel plates (7) delimiting between themselves passages (8A, 8B; 28, 42, 60) of generally plate form containing undulant spacers (9; 32, 34, 36, 37, 44, 47, 48, 53 to 56). A first assembly (8A; 28, 60) of these passages constitutes thermal exchange passages having structure (3 to 5; 39 to 41, 51) for inlet and outlet of fluids adapted to exchange heat with each other. Over at least a portion of its length and of its width, the exchanger has added passages (8B; 42), in reduced or no heat exchange relation with the thermal exchange passages (8A; 28, 60) and provided to fulfill at least one function in addition to the exchange of heat, namely a function of storing liquid and/or recirculation of liquid and/or liquid-vapor separation.
