A heat sink for cooling a heated component, the heat sink comprising a base coupled to the component. In addition, the heat sink comprises at least one thin-walled heat transfer member extending from the base. The heat transfer member comprises an upstream end and a downstream end defined by a fluid flow direction, and a convective surface extending between the upstream end and the downstream end. Further, the convective surface includes a recessed oval dimple having a major axis and a minor axis. The oval dimple is oriented such that its major axis is at an angle theta relative to the fluid flow direction, wherein the angle theta is between 75° and less than 115°.
