Abstract
A heat sink for cooling a heat-generating device includes a base and a cooling section coupled thereto for cooling the device. The cooling section includes a plurality of flow tubes, each flow tube having an inlet, an outlet, and a bounding wall that defines a closed fluid flow path from the inlet to the outlet. Each of the flow tubes includes a central axis that is substantially parallel to a reference plane of the heat-generating device. The flow tubes may be arranged in a layered stack and include a bounding wall that has a thickness that decreases with increasing distance in the layered stack. The flow tubes may also include a cross-sectional area that decreases with increasing distance in the layered stack. Furthermore, the bounding wall of the flow tubes may have a non-planar configuration in a direction generally parallel to the central axis.
