Heat exchanger, has flow guiding unit with flow guiding structures that divert part of fluid, which is guided by substrate surface, where part of fluid is directed towards substrate surface

摘要

The exchanger has two substrates (11, 12) that are kept at a moderate temperature and are attached to a flow channel (13), where a flow guiding unit (20) is arranged in the flow channel. The flow guiding unit has flow guiding structures that divert a part of fluid, which is guided by a substrate surface. The part of the fluid guided in a distance from the substrate surface is directed towards the substrate surface.
