Title
(EN) HEAT EXCHANGER FOR WATER-HEATING APPARATUSES
(FR) ECHANGEUR THERMIQUE DESTINE A DES APPAREILS CHAUFFE-EAU
Abstract
(EN)
A heat exchanger (1), preferably intended for water-heating apparatuses (101) provided with a combustion chamber (23), which comprises: a finned tube bundle (11), comprising a plurality of tubular ducts (2) for circulating at least one heat carrier liquid and a plurality of fins (10) externally associated to the tubular ducts (2); a first and a second manifolds (4, 5) of the heat carrier liquid, positioned at opposite ends of the tube bundle (11) and associated to the tubular ducts (2). The manifolds (4, 5) are provided with a substantially planar rear wall (19) positioned near to an axially outermost fin of the plurality of fins (10) so as to pack the plurality of fins (10) at axially opposite ends. The manifolds (4, 5) comprise at lest one support surface (16) defined at an axially outer position with respect to the rear wall (19) and adapted to cooperate with a wall (12) of the combustion chamber (23) to support the heat exchanger (1) in the water-heating apparatus (101). It is therefore possible to reduce the size of the structural support elements, thus obtaining, in a simple and cost-effective way, and advantageous reduction of the overall size of the heat exchanger.
(FR)
L'invention concerne un échangeur thermique (1), de préférence destiné à des appareils chauffe-eau (101) équipés d'une chambre à combustion (23), qui comporte: - un faisceau tubulaire empenné (11), comprenant plusieurs conduites tubulaires (2) destinées à faire circuler au moins un liquide caloporteur et plusieurs ailettes (10) associées à l'extérieur des conduites tubulaires (2); - des premier et second collecteurs (4, 5) du liquide caloporteur, placés au niveau des extrémités opposées du faisceau tubulaire (11) et associés aux conduites tubulaires (2). Les collecteurs (4, 5) sont équipés d'une paroi arrière sensiblement planaire (19) placée à proximité d'une ailette la plus à l'extérieur sur le plan axial parmi les ailettes (10) de manière à conditionner les ailettes (10) au niveau des extrémités axiales opposées. Les collecteurs (4, 5) comportent au moins une surface support (16) définie au niveau d'une position axiale externe par rapport à la paroi arrière (19) et conçue de manière à coopérer avec une paroi (12) de la chambre de combustion (23) afin de supporter l'échangeur thermique (1) dans l'appareil chauffe-eau (101). Il est ainsi possible de réduire la taille des éléments de support structurel, en vue d'obtenir, de façon simple et peu coûteuse, une réduction avantageuse de la taille globale de l'échangeur thermique.
