Abstract: A method for producing a heat exchanger is disclosed. The method includes a) providing two heat exchanger plates of the heat exchanger that are to be joined to one another; b) wetting at least one common local joining zone of the two heat exchanger plates with solder; c) forming the heat exchanger by brazing the two heat exchanger plates via local heating of the at least one common joining zone.

Abstract: A brazeable metal sheet material for heat exchanger components is used for producing a heat exchanger by a controlled atmosphere brazing process. The metal sheet material is made up of a core material with a brazing layer at least on one side and a corrosion-reducing intermediate layer arranged between the brazing layer and the core material. The core material consists of an Al3000-series alloy or an Al6000-series alloy having a magnesium content of 0.1% to 1.5% by weight. The brazing layer consists of an Al4000-series alloy having a maximum of 0.2% magnesium by weight. The corrosion-reducing intermediate layer consists of an Al1000-series alloy or an Al7000-series alloy having 0.1% to 1.5% magnesium by weight.

Abstract: A brazed heat exchanger, for example a heat exchanger to be used in an air-conditioning system, preferably as a condenser, includes flat tubes extending between a pair of header tubes and fins arranged between the flat tubes. The components are produced from aluminum alloys, and are brazed together using an AlSi braze alloy. The aluminum alloys have a zinc content of no greater than 0.5% before brazing, and zinc from the aluminum alloys diffuses into the braze joints to result in braze joints having an average zinc content of no greater than 0.1%.

Abstract: A number of flat tubes, flat tube heat exchangers, and methods of manufacturing both are described and illustrated. The flat tubes can be constructed of one, two, or more pieces of sheet material. A profiled insert integral with the flat tube or constructed from another sheet of material can be used to define multiple flow channels through the flat tube. The flat tubes can be constructed of relatively thin material, and can be reinforced with folds of the flat tube material and/or of an insert in areas subject to higher pressure and thermal stresses. Also, the relatively thin flat tube material can have a corrosion layer enabling the material to resist failure due to corrosion. Heat exchangers having such flat tubes connected to collection tubes are also disclosed, as are manners in which such tubes can be provided with fins.

Abstract: The invention provides for a manufacturing process of a heat exchanger having a flat tube and fin core. The flat tube and fin core is formed in such a way that free flat tube ends are provided, wherein the flat tube and fin core is brazed in a brazing furnace, and wherein the flat tube ends are received in receptacle openings of a mounting plate and a header forming an enclosed space for receiving a bonding agent for coupling the flat tube ends to the header and mounting plate.
