Abstract
UN PROCESO PARA PRODUCIR UN TUBO DE INTERCAMBIO DE CALOR PLANO (A) QUE TIENE UNOS PASOS DE REFRIGERANTES PLANOS (6) EN SU INTERIOR Y COMPRENDE UNAS PAREDES INFERIOR Y SUPERIOR PLANAS (1, 2), UNAS PAREDES LATERALES OPUESTAS (3, 4) Y UNA PLURALIDAD DE PAREDES DE REFUERZO (5) CONECTADAS ENTRE LAS PAREDES SUPERIOR E INFERIOR (1, 2), DE FORMA QUE SE EXTIENDEN LONGITUDINALMENTE CON RESPECTO AL TUBO (A) Y ESTAN COLOCADAS SEPARADAS ENTRE SI POR UNA DISTANCIA DETERMINADA, Y UTILIZAN UN LAMINADOR (33) QUE COMPRENDE UN RODILLO ACTIVO CENTRAL (35) Y UNA PLURALIDAD DE RODILLOS ACTIVOS PLANETARIOS (36) COLOCADOS ALREDEDOR DE UNA PORCION DE LA PERIFERIA DE UN RODILLO ACTIVO CENTRAL (35) Y DISPUESTOS SEPARADOS CIRCUNFERENCIALMENTE DEL MISMO, ESTANDO EL RODILLO ACTIVO CENTRAL (35) FORMADO CON UNAS RANURAS ANULARES PARALELAS (39, 40) EN SU PERIFERIA. UN MATERIAL EN BRUTO DE UNA HOJA DE ALUMINIO (30) QUE COMPRENDE UNA HOJA DE SOLDAR ES LAMINADA POR EL LAMINADOR (33) Y, POR ELLO, ES REDUCIDA HASTA UN GROSOR PREDETERMINADO PARA FORMAR UNA PORCION PLANA QUE SIRVE DE PARED INFERIOR (2), Y HACER QUE LAS RANURAS ANULARES (39) EN LOS EXTREMOS DE LOS RODILLOS OPUESTOS FORMEN UNAS PORCIONES VERTICALES (12) QUE PROPORCIONAN LAS PAREDES LATERALES RESPECTIVAS (3, 4) Y HACER QUE EL RESTO DE RANURAS ANULARES (40) FORMEN UNOS REBORDES VERTICALES QUE PROPORCIONAN LAS PAREDES DE REFUERZO (5), PROYECTANDOSE LAS PORCIONES VERTICALES Y LOS REBORDES VERTICALES DESDE LA PORCION PLANA DE MANERA INTEGRAL CON LA MISMA. UNA HOJA DE ALUMINIO (20) QUE COMPRENDE UNA HOJA DE SOLDAR ESTA COLOCADA POR ENCIMA DE LOS TRES REBORDES PARA PROPORCIONAR LA PARED SUPERIOR (1) Y SE UNE A LAS PORCIONES VERTICALES PARA HACER QUE LAS PORCIONES VERTICALES ACTUEN COMO LAS PAREDES LATERALES OPUESTAS (3, 4) Y LOS REBORDES DE LA PARED INFERIOR ESTAN UNIDOS CON LA PARED PARA FORMAR LAS PAREDES DE REFUERZO (5).
