Abstract (en)
[origin: WO2018150005A1] Comprising a heat-exchange housing (1) that delimits a circuit for the circulation of a coolant fluid, a plurality of gas circulation pipes (2) that are arranged inside the housing (1) to exchange heat with said coolant fluid, and at least two structural parts (3) provided with a plurality of orifices (4) for receiving the ends of the gas circulation pipes (2) in the respective ends of the heat exchanger housing (1), in which each pipe (2) has two open half-pipes (2a, 2b) that are designed to be mounted opposite one another, the shape of the cross section of the ends of the pipes (2) leaving a join space (e) in the orifices (4) of the structural parts (3), and characterized in that the ends of each of the gas circulation pipes (2) have at least two locking tabs (6a) arranged to overlap the same number of portions (7) of the sides of one of the half-pipes (2a) to at least partially block the join space (e) in the orifices (4) of the structural parts (3).
