Abstract

Devices that have integrated cooling structures for counterflow, two-phase cooling and systems thereof are provided. In one example, a first structure can comprise a first cooling channel. The first cooling channel can have a first value of width that increases as the first cooling channel extends from a first side of a heat transfer area towards a second side of the heat transfer area. Also, a second structure can comprise a second cooing channel. The second cooling channel can have a second value of width that increases as the second cooling channel extends from the second side of the heat transfer area towards the first side of the heat transfer area.
