Flow diversion devices
View Patent ↗Embodiments of flow diversion devices (FDDs) are disclosed herein. An FDD may include a body formed of a body material and a plurality of thermally deformable fins arranged along the body. Individual fins of the plurality of fins may include first and second materials having different coefficients of thermal expansion (CTEs). Other embodiments may be disclosed and/or claimed.
1. An array including at least first and second flow diversion devices disposed adjacent to each other, wherein each of the first and second flow diversion devices comprises:
a separator having a first face and a second face opposite the first face;
a plurality of thermally deformable fins arranged along the first face and the second face, wherein individual fins of the plurality of fins include a first material and a second material, the first material having a lower coefficient of thermal expansion (CTE) than a CTE of the second material, wherein the individual fins include respective first ends that are secured to the respective first or second face of the separator, and second ends that are free from being secured to the respective first or second face of the separator and extend away from the respective first or second face;
wherein the separator includes: a plurality of apertures arranged corresponding to the individual fins along the first and second faces of the separator, wherein the individual fins of the plurality of fins extend into corresponding apertures of the plurality of apertures; and
wherein the individual fins comprise a substantially curved shape in a first temperature state, and a substantially flat shape in a second temperature state, wherein a temperature associated with the first temperature state is lower than a temperature associated with the second temperature state, wherein an individual fin of the first flow diversion device and an individual fin of the second flow diversion device, the individual fin of the second flow diversion device being adjacent to the individual fin of the first flow diversion device, share an individual aperture.
2. The array of claim 1 , wherein:
the plurality of fins comprise a first fin arranged along the first face and a second fin arranged along the second face of the separator, wherein the separator comprises a body of the first and second flow diversion devices;
the first material of the first fin is of a portion of body and the first material of the second fin is of another portion of the body; and
the second material of the first and second fins extends from the body, respectively.
3. The array of claim 1 , wherein the separator is formed from a dielectric or insulating material.
4. The array of claim 2 , wherein the separator is formed from a dielectric or insulating material.
5. An array including at least first and second flow diversion devices disposed adjacent to each other, wherein each of the first and second flow diversion devices comprises:
a separator having a first face and a second face opposite the first face;
a plurality of thermally deformable fins arranged along the first and second faces, wherein individual fins of the second plurality of fins include a first material and a second material, the first material having a lower coefficient of thermal expansion (CTE) than a CTE of the second material, wherein the individual fins include respective first ends that are secured to the respective first or second face of the separator, and second ends that are free from being secured to the respective first or second face of the separator and extend away from the respective first or second face;
wherein the first face and the second face comprise a plurality of cavities arranged corresponding to the individual fins along the first and second faces of the separator, wherein the individual fins of the plurality of fins extend over corresponding cavities of the plurality of cavities; and
wherein the individual fins comprise a substantially curved shape in a first temperature state, and a substantially flat shape in a second temperature state, wherein a temperature associated with the first temperature state is lower than a temperature associated with the second temperature state,
wherein an individual fin of the first flow diversion device and an individual fin of the second flow diversion device, the individual fin of the second flow diversion device being adjacent to the individual fin of the first flow diversion device, share an individual cavity.
6. The array of claim 5 , wherein the separator is formed from a dielectric material or an insulating material.
7. The array of claim 5 , wherein:
the plurality of fins comprise a first fin arranged along the first face and a second fin arranged along the second face, wherein the first and second flow diversion devices comprise a body that includes the separator; and
the first material of the first fin is of a portion of a body material on the first face and the first material of the second fin is of a portion of the body material on the second face.
