Title (EN) DOUBLE TUBE FOR HEAT EXCHANGE
(FR) TUBE DOUBLE POUR ÉCHANGE DE CHALEUR
Abstract:
(EN) Disclosed herein is a double tube for heat exchange. The double tube for heat exchange includes: a spiral pipe having ridges and valleys alternately formed on a circumferential surface thereof along a spiral track thereof and guiding a first fluid to flow therethrough; and an outer pipe receiving the spiral pipe axially inserted thereinto and guiding a second fluid to flow along the circumferential surface of the spiral pipe such that the second fluid exchanges heat with the first fluid, wherein the ridges contact with an inner surface of the outer pipe such that no gap is formed between the ridges and the inner surface of the outer pipe.
(FR) L'invention concerne un tube double destiné à un échange de chaleur. Le tube double destiné à un échange de chaleur comprend : un tuyau en spirale comportant des crêtes et des creux formés en alternance sur sa surface circonférentielle le long d'une piste en spirale associée et guidant l'écoulement d'un premier fluide en son sein ; et un tuyau externe recevant le tuyau en spirale inséré axialement en son sein et guidant l'écoulement d'un second fluide le long de la surface circonférentielle du tuyau en spirale de sorte que le second fluide échange de la chaleur avec le premier fluide, les crêtes entrant en contact avec une surface interne du tuyau externe de sorte qu'aucun espace ne soit formé entre les crêtes et la surface interne du tuyau externe.
