DEVICE AND METHOD OF GENERATING A SECOND VARIATION OF TMPERATURE CAUSED BY A FIRST VARIATION OF TEMPERATURE

摘要

A device for generating a second temperature variation &Dgr;T2 from a first use temperature variation &Dgr;T1, includes an elastocaloric material layer, having an internal temperature which is able to vary by &Dgr;T2 in response to a given mechanical stress variation &Dgr;&sgr; applied to the elastocaloric material layer. The variation &Dgr;&sgr; being induced by the first use temperature variation &Dgr;T1 There is a suspended element in mechanical contact with the elastocaloric material layer so as to apply to this layer a mechanical stress that varies in response to the use temperature variation &Dgr;T1. The suspended element is arranged so as to make the mechanical stress applied to the elastocaloric material layer vary by &Dgr;&sgr; in response to the temperature variation &Dgr;T1 to generate the second temperature variation &Dgr;T2.
