Title (EN) CORRUGATED INSERT FOR HEAT EXCHANGER
(FR) ELEMENT ONDULE POUR ECHANGEUR DE CHALEUR
Abstract: front page image
(EN)A corrugated insert for a heat exchanger has the form of a plate with corrugations (1), the walls (2) of which form channels (3) for the passage of the heat-carrying medium and are provided, along their length, with protrusions (4) and recesses (5), which are grouped in pairs, are placed opposite to each other on the adjacent walls (2) of the corrugations (1) and are alternating with plain sections so as to ensure periodical throttling of the flow of the heat-carrying medium and thus to intensify the heat exchange process. The length of each plain section (6) does not exceed five hydraulic diameters of the plain section (6) of the channel (3), the internal rounding-off radius of the top of the corrugation (1) does not exceed the difference between a quarter of the pitch of the corrugation (1) and a half of the thickness of the wall (2), whereas the protrusions (4) and recesses (5) on the walls (2) of the corrugations (1) are of a length which ensures the intensification of the heat exchange process.
(FR)Un element ondule pour un echangeur de chaleur possede la forme d"une plaque ayant des ondulations (1), dont les parois (2) forment des canaux (3) pour le passage du milieu calorifere et sont pourvues sur leur longueur de protuberances (4) et d"evidements (5) qui sont groupes par paires, places en opposition les uns par rapport aux autres sur les parois adjacentes (2) des ondulations (1) et alternent avec des sections planes de maniere a assurer un etranglement periodique du flux du milieu calorifere et intensifier ainsi le processus d"echange de chaleur. La longueur de chaque section plane (6) ne depasse pas 5 diametres hydrauliques de la section plane (6) du canal (3), le rayon interne de l"arrondi du sommet de l"ondulation (1) n"est pas superieur a la difference entre un quart de l"amplitude de l"ondulation (1) et la moitie de l"epaisseur de la paroi (2), tandis que les protuberances (4) et les evidements (5) des parois (2) des ondulations (1) ont une longueur qui assure l"intensification du processus d"echange de chaleur.
