Title (EN) TUBULAR-LAMELLAR HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR TUBULAIRE LAMELLAIRE
Abstract: front page image
(EN)A tubular-lamellar heat exchanger comprises tubes (1) for the passage of a heat-carrying medium at a temperature which are fixed in openings (9) pierced in a set of plates (2, 3) so that the adjacent plates (2, 3) form a plurality of channels for the passage of a heat-carrying medium at another temperature. Each of the plates (2, 3) is provided with protrusions (4) and recesses (5) forming in the channels symmetrical diffusing and coverging zones for creating turbulences in the wall layer of the flow of the heat-carrying medium. The plates (2 and 3) are provided with straight parts (8) located between the diffusing and converging zones and placed on the adjacent plates (2 and 3) opposite to each other.
(FR)Un echangeur de chaleur tubulaire lamellaire comprend des tubes (1) pour le passage d"un milieu calorifere a une certaine temperature. Ces tubes sont fixes dans des ouvertures (9) percees dans un ensemble de plaques (2, 3) de maniere que les plaques adjacentes (2, 3) forment une pluralite de canaux pour le passage d"un milieu calorifere a une autre temperature. Chacune des plaques (2, 3) est pourvue d"elements en saillie (4) et d"elements en retrait (5) formant des zones symetriques diffusantes et convergentes a l"interieur des canaux de maniere a creer des turbulences dans la couche peripherique de l"ecoulement du milieu calorifere. Les plaques (2 et 3) sont pourvues de parties droites (8) situees entre les zones diffusantes et convergentes et placees sur les plaques adjacentes (2 et 3) l"une en face de l"autre.
