Résumé

As a new and efficient refrigeration technology, elastothermal refrigeration with high refrigeration efficiency and specific refrigeration power is considered to be a promising alternative to traditional vapor compression technology. Compared with shape memory alloys, elastomers require much lower applied stresses to produce elastocaloric effect. In this paper, Elastocaloric effects of cylindrical natural rubber under 4 strains and 4 tensile rates were studied on a self-made experimental bench. The results showed that the elastocaloric effect was almost constant under the periodic strain force of simple harmonic cycle, and the greater the strain, the more obvious the influence of tensile rate on elastocaloric effect. Furthermore, when the strain of cylindrical natural rubber was 250%, the entropy of the stretch-shrink cycle increased with the increase of the tensile rate, but did not change with the ambient temperature.
