Abstract
A cooler has a plurality of layers arranged in a stack and connected to one another along their surfaces. Each layer has openings allowing for three-dimensional flow of the coolant between an intake and an outlet. The flow resistance or the gradient of flow resistance increases from the intake to the outlet so that the coolant is increasingly forced to concentrate at the cooling surface as coolant flows from the intake to the outlet.
