    Housing can be of different types. Generally, the ducts are fixed at their ends between two support pieces coupled at each end of the housing, both support pieces having a plurality of holes for receiving the ends of the respective tubes.
    In the prior art, heat exchangers for gases comprising gas circulation ducts formed from two open semi-ducts designed to be mounted opposite each other are known so that the sides of a semi-duct overlap portions of the respective sides of the other semi-duct.
    EP2096294 describes a heat exchanger provided with this type of gas ducts formed from two open semi-ducts, which have the advantage, compared to ducts formed in one piece, that facilitate assembly without risk of ruptures of the disturbing elements, which are arranged inside the gas ducts to improve the heat transfer of the gas flow. These disturbing elements are usually configured as fins of thin thickness, which are easily damaged by the effect of pressure when they are introduced laterally into the ducts formed in one piece. On the other hand, the exchangers that include gas circulation ducts formed from two open semi-ducts, such as those described in said patent, facilitate the assembly of the disturbing elements, which allows reducing the thickness of these elements, and with This also reduces the overall costs of the exchanger.
    However, the gas circulation ducts formed from two open semi-ducts have the disadvantage that they do not ensure optimum contact between components (disruptors and semi-ducts). In addition, the cross-section of these ducts results in a geometry that entails the appearance of a joint space (e) in the holes of the support pieces that receive the ends of the same gas circulation ducts. The sealing between the support pieces and the ends of the gas conduits is carried out by welding using a brazing material that is introduced into said joint space (e) for the purpose of ensure an optimum level of sealing between components, however, the joint space (e) in the holes of the support pieces is too wide, so it is necessary to use a lot of welding filler material and, nevertheless, Optimal sealing quality is not ensured.

    Description of a preferred embodiment
    Next, a preferred embodiment of a gas heat exchanger, and a gas circulation conduit, of the present invention is described, referring to Figures 1 to 6.
    The gas exchanger of the present invention comprises;
    - a heat exchange housing 1 that delimits a circuit for the circulation of a cooling fluid,
    - a plurality of gas circulation ducts 2 that are housed inside the housing 1 to exchange heat with the cooling fluid, and
    - two structural parts 3 provided with a plurality of holes 4 for receiving the ends of the gas ducts 2 at the respective ends of the heat exchanger housing 1.
    Figure 1 illustrates a schematic exploded view of the claimed gas exchanger illustrating by way of example, a gas circulation conduit 2 formed by two open semi-conduits 2a, 2b, configured by two "U" shaped plates, which they receive inside a disturbing element 5 to improve the heat transfer of the
    gases The assembly of each of the gas circulation ducts 2 is carried out by mounting both semi-ducts 2a, 2b opposite each other so that the sides of a semi-duct 2b overlap a portion 7 of the respective sides of the other semi-conduit 2a, resulting in the cross-section of the ends of the gas conduits 2 with a geometry leading to the appearance of a joint space (e) in the holes 4 of the structural parts 3 that receive the ends of said conduits 2 gas circulation.
    Figure 6 shows the cross-section of one end of a gas circulation duct 2 of the prior art, formed from two semi-ducts 2a, 2b open in a "U" shape and mounted inside a hole 4 of the structural part 3. which receives the 10 ends of the gas circulation ducts 2. This figure shows the space (e)
    of gasket resulting from the particular geometry of the cross section of the gas conduit 2.
    The claimed exchanger has the advantage that the surface of the ends of the gas circulation ducts 2 includes at least two blocking flanges 6a arranged 15 to seal said joint space (e) and act as a barrier to the material
    of welding filler (see figure 5).
    In the embodiment described and shown in the figures, a plurality of tabs 6 are provided that extend discreetly along the sides of an open half-conduit 2b configured as a "U" shaped plate. , except in a portion (D) of the end of the semi-conduit 2b. These tabs 6 are configured as projections that can be folded and overlapped on portions 7 of the sides of another open plate or semi-conduit 2a, for forming the gas flow duct 2. In the embodiment described the length (L) of the projections is provided of about 15 mm, however this length (L) may vary depending on the design of the exchanger.
    At least a couple of the said projections are positioned at the end of the gas circulation conduit 2 to act as a blocking flange 6a. For example, both locking tabs 6a can be located at a distance (D) of 0.5 mm from the end of the plate or semi-duct 2b and act as a stop to delineate the position of each structural part 3. The width (A) of these projections acting as locking tabs 6a 30 can be, for example, about 0.5 mm to seal, at least partially, the joint space (e) of the holes 4 of the pieces 3 structural and act as a barrier of the welding filler material. The remaining projections that extend along the sides of the plate or semi-conduit 2b are designed to ensure contact between components during the sealing operation.

Optionally, the inner cavity of the gas duct 2 can accommodate a gas disturbing element 5 that is inserted between the open semi-ducts 2a, 2b without risk of being damaged. Thanks to this, the thickness of this component can be reduced, which makes it possible to reduce the final cost of the exchanger.
    In a second stage, the projections or tabs 6 for blocking the ends of each gas duct 2 are folded to overlap two portions 7 of the sides of one of the semi-ducts 2a, thus ensuring contact with the element 5 disturbing during the sealing stage. Then, in a third stage, the ends of each gas circulation duct 2 are inserted into the holes 4 of the respective structural parts 3 that receive the ends of said gas ducts 2, until they meet the projections that act at tab mode 6a lock (see figure 4).
    In a fourth stage, a sealing operation is carried out by filling the sealing space (e) of the holes 4 of the structural parts 3 that receive the ends of the gas conduits 2 with welding material. Then, all components are welded.
    As mentioned in the description of the invention, the claimed manufacturing method ensures a good quality of welding ("brazing or welding"), and thus, obtaining a more robust exchanger and a longer service life. long
