Summary

Elastocaloric cooling is an environment-friendly technology that could supplant greenhouse-gas refrigerants. The pursuit of compact and efficient elastocaloric devices is the cornerstone of its developmental trajectory. In this study, we propose an alternative actuation method called coil-bending to achieve the elastocaloric cooling in lower driving force. Through the implementation of coil-bending, we have developed a compact elastocaloric air cooler with the large specific heat transfer area (12.6 cm2·g−1) and the constant cold zone of NiTi wires. This innovative design allows continuous cold air output through the constant cold zone. The elastocaloric air cooler outputs a continuous cold airflow with a temperature drop of 10.6 K and achieves a specific cooling power of 2.5 W·g−1, all at a low specific driving force of 26 N·g−1. Notably, the cooler exhibits a system coefficient of performance of 3.7 (ratio of cooling power to rotated mechanical power). The performance of our coil-bending system, with its efficient and compact design, showcases the viability of elastocaloric cooling technology in the field of air conditioning.
