Abstract (en)

A particularly compact bi-thermal gas-liquid heat exchanger (1) having a high heat exchange efficiency is described, preferably, but not exclusively used as a bi-thermal gas-water heat exchanger for water heating apparatuses. The heat exchanger (1) comprises at least one tube-in-tube tubular conduit (3) comprising a shaped inner tubular conduit (4) in which an inner liquid flowpath (5) for the circulation of a first heat carrier liquid is defined and an outer tubular conduit (6) mounted around the shaped inner tubular conduit (4) and defining, with the inner tubular conduit (4), at least one gap (7', 7"; 8', 8") in which an outer liquid flowpath for the circulation of a second heat carrier liquid is defmed. According to the invention, the tube-in-tube tubular conduit (3) further comprises at least one flow rate splitting element (27) arranged in the at least one gap (7', 7"; 8', 8") defmed between the shaped inner tubular conduit (4) and the outer tubular conduit (6) for splitting the flow rate of the second heat carrier liquid between a gas inlet side zone and a gas outlet side zone of the at least one gap (7', 7"; 8',8").
