ABSTRACT:
A heat sink having a pressure gradient includes a heat sink base plate. Individual fins extend from the base plate and have variable spacing. First adjacent fins form a high pressure zone at a first end of the heat sink, wherein the first adjacent fins are separated by a first distance therebetween. Second adjacent fins form a low pressure zone at a second end of the heat sink, opposite the first end, wherein the second adjacent fins are separated by a second distance, greater than the first distance.
