Abstract
A heat exchanger comprising a substrate that comprises a bottom side and a top side; a unit for generating a directed fluid stream with a flow direction that is tangential to the bottom side and to the top side of substrate; webs projecting from the top side of substrate and perpendicular to the flow direction, lying one after the other in the flow direction, wherein a height of the webs is less than a spacing of adjacent webs in the flow direction; and a plurality of regularly arranged channels extending through the substrate.

A heat exchanger comprising:
- a substrate that comprises a bottom side and a top side;
- a unit for generating a directed fluid stream with a flow direction that is tangential to the bottom side and to the top side of the substrate;
- webs projecting from the top side of the substrate and perpendicular to the flow direction, lying one after the other in the flow direction, wherein a height of the webs is less than a spacing of adjacent webs in the flow direction;
- and
- a plurality of regularly arranged channels extending through the substrate;
- wherein the substrate is placed via spacers on an object and a height of the spacers is greater than the height of the webs;
- and
- wherein the height of the spacers is less than a length of the channels in the flow direction.
