HEAT EXCHANGE APPARATUS WITH IMPROVED HEAT EXCHANGE RATE AND ITS FABRICATION PROCESS

摘要

A heat exchange device including a first surface configured to be in contact with a source of heat to be discharged and a second surface configured to be in contact with a coolant. The device includes a plurality of recesses fluidically insulated from one another, each recess leading onto the second surface via at least one channel, each channel having a length and a transverse size that prevents the coolant from entering the recess. The second surface has better wettability properties with respect to the coolant and the inner surfaces of the channels and the recesses have wettability properties less than or equal to those of the second surface.
