Definitions
- the invention relates to an aluminum-based composite material for a heat exchanger with an aluminum alloy base material and with an aluminum material plated on the base material.
- the parts produced from this composite material must be soldered on the side opposite the cladding, either the base material being provided with a brazing layer on the sides opposite the cladding or soldered to a structural part coated with such brazing material.
- This known composite material can be soldered only from one side, resulting in a further increase in strength, a restriction by the fact that the base material must not fall below a certain Dickenver ⁇ ratio to the plated aluminum material.
- the invention is therefore an object of the invention to improve a composite material based on aluminum for a heat exchanger of the type described so that due to an increase in strength, the wall thickness of the manufactured of such a composite components can be reduced.
- the invention solves this problem by the fact that the base material of a hardenable aluminum alloy series 7000 or 2000 and the plated aluminum material made of unalloyed aluminum.
- the base material consists of a hardenable aluminum alloy of the series 7000 or 2000
- the higher strength of this material can be utilized and depending on this, the wall thicknesses of the components of a heat exchanger manufactured therefrom can be reduced.
- the use of a hardenable aluminum alloy of the series 7000 or 2000 despite the inadequate for a brazing temperature resistance possible because on this base material unalloyed aluminum is plated, which has a higher melting point and is suitable for brazing.
- the base material of 7000 or 2000 series aluminum alloy can be used for heat exchangers comparable to known aluminum-based composites, so that the strength advantage of the 7000 or 2000 series aluminum alloys can be fully utilized.
- the brazing material required for brazing can be applied in a manner known per se to the unalloyed aluminum layer or assigned to the component with which a brazed joint is produced. should be. Since opposing sides of the base material can also be clad with unalloyed aluminum, there are no restrictions as regards the solderability of components produced from such composite materials.
- the plated, unalloyed aluminum not only ensures the suitability of the composite material for brazing, but at the same time serves as a diffusion barrier between the base material and the brazing alloy, so that the diffusion effects impairing the solder joint are prevented.
- the layer of unalloyed aluminum prevents premature evaporation of alloying elements, such as zinc, from the base material during soldering, especially in a vacuum, which adversely affects the soldering process and subsequently the solder joint.
- an ingot of an aluminum alloy of the series 7000 or 2000 and on the other hand a rolled, oriented and sawn board of unalloyed aluminum can be used, with respect to the dimensions of the base ingot and the board, the material and process related Width and elongation effects have to be taken into account, in particular with regard to the required platelet layer thickness of the finished composite material.
- brazing By brushing, the later contact surfaces of the basic bar and of the board are cleaned and roughened, before the board aligned with respect to the base bar is in position relative to the basic bar Welding is fixed.
- appropriate aluminum blanks are to be provided on opposite sides of the basic bar. If an additional hard solder layer is to be provided, then a brazing board is to be placed on the aluminum board and likewise fixed by welding. As brazing z. B.
- the weld seams are arranged so that fold formation during plating rolling can be avoided and optionally air can be rolled out between the base bar and the sinker or between the sinkers at locally provided locations.
- the rolled composite prepared in this manner is then heated to hot rolling temperature to subsequently produce the composite by hot rolling in the form of a hot strip.
- the composite material is processed to the desired semifinished product by further processing steps, for example by cold rolling, stretching, degreasing, heat treatment, longitudinal splitting and cutting to length.
