Abstract
(EN) A method for manufacturing a refrigerant guide tube of a heat exchanger and a refrigerant guide tube manufactured using the method and a heat exchanger with the refrigerant guide tube are disclosed. The refrigerant guide tube includes tube body (2) and channels (11, 21, 22) extending through a wall of the tube body (2). The tube body (2) is formed by a butt joint of side edges of more than one bar-shaped plate materials along the length direction. The method allows forming the refrigerant channels (11, 21, 22) of the guide tube before or during forming the tube body (2) when the method is used to manufacture the guide tube, so as to avoid directly forming the channels (11, 21, 22) on the tube body (2) and make the process of manufacture the guide tube simpler and more convenient.
(FR) L'invention concerne un procédé pour fabriquer un tube de guidage de réfrigérant d'un échangeur de chaleur, un tube de guidage de réfrigérant fabriqué selon ce procédé et un échangeur de chaleur équipé de ce tube de guidage de réfrigérant. Ledit tube de guidage de réfrigérant comprend un corps de tube (2) et des canaux (11, 21, 22) s'étendant à travers une paroi d'une corps de tube (2). Ledit corps de tube (2) est formé par assemblage bout à bout d'arêtes latérales d'une pluralité de matériaux en plaques en forme de barre dans le sens longitudinal. Lorsqu'il est mis en oeuvre pour la fabrication du tube de guidage, ce procédé permet de former les canaux de réfrigérant (11, 21, 22) du tube de guidage avant ou pendant la formation du corps de tube (2), de façon à éviter de devoir former directement les canaux (11, 21, 22) sur le corps de tube (2). Ce procédé de fabrication de tube de guidage est ainsi plus simple et plus pratique.
