Abstract: According to an aspect of the present invention, the foregoing needs are addressed by an apparatus for cooling a heat source (10), including a carrier plate (19) having a channel (28, 38) therein. The channel has an inlet end (30) and an outlet end (31). A cooling region (46) is disposed in the carrier plate and is in communication with the channel. The cooling region is sized to be disposed proximate the heat source. A member (40) having an orifice (42) therein is disposed in the cooling region. A ratio between a thickness of the member and a width of the orifice is less than 0.9.
