Abstract:
A cooling device comprising;a semiconductor package substrate having a top-side and back-side surface, the top-side surface having a semiconductor chip mounted thereto, and the back-side surface being opposite the top-side surface; and a cooling channel housing, the channel housing in conjunction with at least a portion of the back-side surface defining a right and a left flow channel, the left and right flow channels being substantially parallel to each other and being separated by a dividing wall formed in the channel housing, the left flow channel comprising a left inlet section, a left heat transfer section, and a left outlet section, the left heat transfer section having a cross-sectional area perpendicular to the intended direction of flow smaller than the cross-sectional areas perpendicular to the flow direction of the left inlet and left outlet sections, the right flow channel comprising a right inlet section, a right heat transfer section, and a right outlet section, the right heat transfer section having a cross-sectional area perpendicular to the intended direction of flow smaller than the cross-sectional areas perpendicular to the flow direction of the right inlet and right outlet sections.
