METHOD FOR MANUFACTURING TUBE PLATE FIN HEAT EXCHANGERS

摘要

Method for manufacturing tube fin heat exchangers, (TFP), by brazing metal components of mainly aluminium or aluminium alloys including the following steps: - making the components of the TFP heat exchanger including the tubes (2) and plate fins (6) with collars (7), - providing a pre-braze coating with filler material on the tubes (2), or providing a (welded) clad tube (2) with a flux coating, - assembling the components including attaching the fins (6) to the tubes (2), - heating the assembled components forming the brazed connection between the tubes (2) and fins (6).
