Title (EN) PLIABLE TUBULAR HEAT EXCHANGER
(FR) ÉCHANGEUR THERMIQUE SOUPLE DE FORME TUBULAIRE
Abstract: front page image
(EN)This invention concerns a tubular heat exchanger, comprising and external tube (11 ) in which extends at least one internal corrugated tube (12) and where the heat exchange takes place between a first fluid flowing in a tube and a second fluid flowing in the other tube. Between the external tube (11 ) and the internal corrugated tube (12) is positioned a filiform element (13) with a helicoidal pitch acting as a spacer between said tubes along all their lengths. The external tube and the internal tube are pliable, and the helicoidal filiform element is wrapped around the internal tube and rests against the internal surface of the external tube to form an annular conduit between said tubes.
(FR)La présente invention concerne un échangeur thermique de forme tubulaire, comportant un tube extérieur (11) dans lequel s'étend au moins un tube ondulé intérieur (12) et où l'échange thermique se produit entre un premier fluide circulant dans un tube et un second fluide circulant dans l'autre tube. Entre le tube extérieur (11) et le tube ondulé intérieur (12) est disposé un élément filiforme (13) avec un pas hélicoïdal agissant comme entretoise entre lesdits tubes dans le sens de la longueur. Le tube extérieur et le tube intérieur sont souples, et l'élément filiforme hélicoïdal est enveloppé autour du tube intérieur et est en appui contre la surface interne du tube extérieur pour former un conduit annulaire entre lesdits tubes.
