FIELD: power engineering.
SUBSTANCE: heat exchange system includes a heat exchanger comprising a tube, through which the first fluid medium flows, and multiple ribs made of thin plates attached to the tube and ordered in parallel to each other in direction, along which the tube expands, and a fan to input the second fluid medium between ribs. A rib comprises concave parts and convex parts and is continuously and cyclically formed as a zigzag line. Concave and convex parts are ordered to expand in the direction that crosses the direction of movement of the second fluid medium leaking via ribs, and the flow of the second fluid medium leaking between the ribs is cyclically alternating.
EFFECT: development of a heat exchanger that may reduce thickness of the border layer of the flow near the rib surface thus making it possible to improve efficiency of a heat exchanger using this invention.
