Cooling apparatus and method of assembling same

摘要

A cooling apparatus includes first and second laminations each having a plurality of openings wherein the openings of the first and second laminations are substantially coincident when the laminations are disposed in identical orientations and the first lamination is aligned with and overlies the second lamination. The first and second laminations are bonded in a stacked and aligned relationship in different orientations such that passages are formed extending through the laminations.
