INDU6 - AddXChange

One challenge of e-mobility is to minimize the charging times of the high-performance batteries used. To achieve this, electric vehicles must be charged at the highest possible charging currents. This charging process generates heat losses that must be efficiently dissipated with the aid of a heat exchanger to prevent temperature-related damage to the battery. For this reason, the performance of existing heat exchangers must be further improved.

Aim and approach

The aim of the AddXChange project is the holistic qualification of copper as a material for the binder jetting process (BJT) using the example of heat exchangers for electromobility. In this additive manufacturing process, liquid binder is selectively applied to a powder bed and solidified to form a workpiece. The research focus is on the holistic consideration of the entire process chain as well as the targeted porosity adjustment and the introduction of flow-conducting structures.

Optimized process strategies are to be developed by means of an iterative procedure, as well as ae, a and consideration of the interactions between the material and the individual process steps. The whole  process chain from powder production, through the binder jetting process, to application is to be considered and the individual steps coordinated.
