| 摘要 |
The invention relates to a device for generating a second temperature variation DeltaTau2 from a first use temperature variation DeltaTau1, comprising an elastocaloric material layer (30), the internal temperature of which is capable of varying from DeltaTau2 in response to a given variation Deltasigma in a mechanical stress applied onto said elastocaloric material layer, the given variation Deltasigma being induced by the first temperature variation DeltaTau1, and a suspended element (24) in mechanical contact with the elastocaloric material layer such as to apply, onto said layer, a mechanical stress that varies in response to the use temperature variation DeltaTau1. Said suspended element (24) is set up such as to cause variation, from Deltasigma, in the mechanical stress applied onto the elastocaloric material layer in response to the temperature variation DeltaTau1 such as to thereby generate the second temperature variation DeltaTau2. |
