Title:
THERMALLY-ACTUATED ELEMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/003008
Kind Code:
A1
Abstract:
Provided is a thermally-actuated element having a high degree of freedom for setting a differential across a wide temperature band, and with which it is also possible to set a comparatively low differential. This plate-shaped thermally-actuated element 100, which has a shape that changes in conjunction with a change in temperature, has a cross-section at a room temperature that is a composite curve formed by combining a plurality of curves, the cross-section being at different curves at a center portion 121 of the thermally-actuated element and an outer peripheral portion 122 surrounding the center portion. The shape of the thermally-actuated element changes at a prescribed temperature outside the range of room temperature, the cross-section of the thermally-actuated element after the shape change is a composite curve formed by combining a plurality of curves, and the cross-section is at different curves at the center portion of the thermally-actuated element and the outer peripheral portion surrounding the center portion. A boundary 123 between the center portion and the outer peripheral portion is the same before and after the shape change of the thermally-actuated element.
