Abstract
A flow control device and a related cooled electronic system are provided. The electronic system comprises a first heat dissipation component and a second heat dissipation component. The flow control device controls an amount of an air flow to the first heat dissipation component and the second heat dissipation component. In one illustrative embodiment, the flow control device comprises: a memory metal component coupled to the first heat dissipation component and the second heat dissipation component and a movable component comprising a first end and a second end. The first end is coupled to a point between two ends of the memory metal component and the second end is movable with respect to the first end. In response to a temperature difference between the first heat dissipation component and the second heat dissipation component, the second end approaches the first heat dissipation component or the second heat dissipation component.
