Abstract: The heat exchanger has a helically bound bundle (2) of tubes fixedly mounted inside a casing fitted with a pipe for evacuating gases generated by a burner (6). The casing (1) is made of a heat-resistant plastic material. A containment mechanism comprising a tie rod (5) and an annular plate (30) ensures mechanical containment of the bundle in an axial direction to absorb thrust loads resulting from fluid internal pressure

Abstract: The invention relates to a deflector for a condensation heat exchanger and to an exchanger provided with such a deflector. Said deflector (2) is characterised in that it includes two front (3) and rear (4) cups of which the inner surface (311, 411) of the bottom is designed in relief so as to have at least one circulation groove (34, 44), the two cups being assembled on either side of a central partition (5) so that each groove forms, with said partition, a channel in which a heat-transfer fluid is intended to circulate, the channels of the front and rear cups being connected via an opening (50) bored into said central partition (5), so that said heat-transfer fluid can circulate from an inlet coupling (40) to an outlet coupling (30) of the deflector, through said channels by flowing on either side of said central partition.

Abstract: The invention relates to a condensation heat exchanger which comprises:—at least two concentric bundles (5, 5′) of tubes made from a material that is a good thermal conductor, inside which tubes a heat-transfer fluid is intended to circulate, each bundle of tubes (5, 5′) comprising a series of tubes (50, 50′) in the form of an arc of a circle, the tubes of each bundle (5, 5′) being arranged in parallel planes with a gap (53, 53′) between two adjacent tubes (50, 50′),—a single collector (6) made of a material that is a good conductor of heat and to which the two ends (51, 51′, 52, 52′) of each tube (50, 50′) of the various bundles (5, 5′) are connected, this collector (6) being equipped with inlet (61) and outlet (62) couplings. This exchanger is notable in that the collector (6) comprises several partitions delimiting various channels, which allow the fluid that is to be warmed up to be made to circulate in the various successive bundles from the outermost bundle to the innermost bundle.

Abstract: A deflector for a condensation heat exchanger and to an exchanger provided with such a deflector. The deflector includes two front and rear cups with inner surfaces at the bottom designed in relief so as to have at least one circulation groove. The two cups are assembled on either side of a central partition so that each groove forms, with the partition, a channel in which a heat-transfer fluid is intended to circulate. The channels of the front and rear cups are connected via an opening bored into the central partition, so that the heat transfer fluid can circulate from an inlet coupling to an outlet coupling of the deflector, through the channels by flowing on either side of the central partition.
