Abstract
A method and apparatus for heat-dissipation utilizing a fin assembly including one or more fins organized on a wall or base surface. The fins can extend into a flow of fluid passing along the wall or base surface to convectively cool the fins, which can transfer heat from heat-producing components, such as electronics.
Claims16
A fin assembly exposed to a flow of fluid for thermal cooling, comprising:
- a base surface configured to transfer heat from component;
- and
- a set of fins, extending from the base surface into the flow of fluid, each fin defining a respective fin axis parallel to the base surface and spaced from an adjacent fin to form a linear fluid flow path defining a flow axis therethrough parallel to the flow of fluid, with at least one fin of the set of fins including an angled orientation with respect to the flow axis and the at least one fin of the set of fins including a first planar face defining a first side and a second planar face separated from the first planar face by a width of the fin and defining a second side;
- and
- a set of openings extending between the first planar face and the second planar face, each opening including an inlet and an outlet and defining an opening axis therethrough that is at an angle with respect to a wall axis being defined perpendicular to the first planar face, wherein the opening distributes a fluid flow therethrough based upon a pressure differential developed on the first and second sides of the at least one fin, wherein the fluid flow through the openings is entrained by the flow of fluid in the linear fluid flow path to thereby define a non-linear flow path;
- wherein the set of fins is configured to dissipate heat from the component to fluid adjacent the set of fins.

A finned heat exchanger, comprising:
- a wall configured to transfer heat from a component;
- and
- a set of fins extending from the wall into a flow of fluid, each fin defining a respective fin axis parallel to the wall and spaced from an adjacent fin to form a linear fluid flow path defining a flow axis therebetween parallel to the flow of fluid, with at least one fin of the set of fins including a first planar face and a second planar face separated by a width of the fin and a set of openings extending between the first planar face and the second planar face;
- wherein each opening of the set of openings includes an inlet and an outlet defining an opening axis therethrough that is offset from a wall axis being defined perpendicular to the first planar face and the second planar face by an opening angle, wherein the opening distributes a fluid flow based upon a pressure differential developed on the first side and the second side of the at least one fin, wherein the fluid flow through the set of openings is entrained by the flow of fluid in the linear fluid flow path to thereby defines a non-linear flow path;
- and
- wherein at least one fin axis is at an angle relative to the-flow axis to provide increased surface area of one of the first or second planar face confronting the flow of fluid to dissipate heat from the component.
