Device and method for generating a second temperature variation from a first temperature variation

摘要

A device for generating a second temperature variation ΔT₂ from a first use temperature variation ΔT₁, includes an elastocaloric material layer, having an internal temperature which is able to vary by ΔT₂ in response to a given mechanical stress variation Δσ applied to the elastocaloric material layer. The variation Δσ being induced by the first use temperature variation ΔT₁ 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 ΔT₁. The suspended element is arranged so as to make the mechanical stress applied to the elastocaloric material layer vary by Δσ in response to the temperature variation ΔT₁, to generate the second temperature variation ΔT₂.
