Title (EN) HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR
Abstract: front page image
(EN)A heat exchanger comprising a tube (2) for subjecting a medium to heat exchange, header pipes (4) for distributing and collecting the medium, and connectors (8) for joining medium supplying or receiving external pipes thereto, all of which being unitarily assembled and brazed together, wherein the connectors (8) are provided with stepped portions (83) for preventing brazing flux and brazing filler metal from infiltrating into joint surfaces (82) with respect to the external pipes, the stepped portions being formed continuously over the whole of outer circumferences of the connectors (8), the joint surfaces (82) being disposed so as to face in the downward direction with respect to a vertical plane when a flux applying operation is carried out.
(FR)L'invention concerne un échangeur de chaleur comportant un tube (2) permettant de soumettre un milieu à un échange de chaleur, des tuyaux d'extrémité (4) permettant de distribuer et de recueillir le milieu, ainsi que des raccordements (8) permettant de raccorder des tuyaux extérieurs servant à amener ou à recevoir le milieu, le tout étant assemblé et brasé de manière à former un tout. Les raccordements (8) sont pourvus de parties échelonnées (83) destinées à éviter que le flux de brasage fort et le métal d'apport de brasage fort ne s'infiltrent dans des surfaces de joint (82) par rapport aux tuyaux extérieurs, les parties échelonnées étant formées de manière continue sur tout le pourtour extérieur des raccordements (8) et les surfaces de joint (82) étant orientées vers le bas par rapport à un plan vertical, lors de l'exécution d'une opération d'application de flux.
