Paper Abstract

This paper introduces a novel concept of using semiconductor heat pumpmodules to heat and cool Nitinol shape memory alloy (SMA) wires in an effort to reducethe response time for complete thermal cycling. An analytical heat transfer model isdeveloped to provide a quantitative comparison between the effectiveness of semiconductormodules and other conventional modes of heating and cooling SMA wires. Results of theheat transfer modeling indicate that semiconductor heat pump modules can reduceheating/cooling cycle time by an order of magnitude compared to free or forced convectionalone.
