Investigation of single wire elastocaloric air cooling potential.

Number: pap. 0027

Author(s) : MICHAELIS N., WELSCH F., KIRSCH S. M., et al.

Summary

The following contribution provides analyses of the air cooling potential of elastocaloric shape memory alloys (SMAs) in form of NiTiCo wires. An essential step consists in developing a scientific test setup, which offers the ability to determine the air-cooling potential under varying conditions like wire geometry, material composition, and process parameters.

With the help of this test setup the influence of different airflow rates on the heat transfer from SMA wire to air and the coherent heat transfer coefficients as well as the expectable air temperature ?T values are determined and presented in this contribution. Analysing these parameters will greatly support the simulation, development and construction of elastocaloric air cooling devices to provide environmentally friendly alternatives to the prevalent vapour compression based cooling principles.
