FIELD: heating.
SUBSTANCE: invention concerns thermal engineering and can be applied in heat-structure cooling systems. It can be gas turbine vane or supersonic gas nozzle. It can be applied in heat exchange plants, steam generators, cryogenic equipment and other aggregates. Device for heat exchange between wall and medium flow includes wall and detail of porous permeable material connected to it. The detail features holes directed along the flow, opened at one side and connected to medium supply or drainage elements, and closed at the other end. The detail is made in the form of undular spacer consisting of contact sectors and heat exchange ridges. Holes are formed by spacer ridges and wall and feature figured cross-section. Contact sectors are connected to wall, and spacer pore diametre in vicinity of contact sector is less than in the ridge area.
EFFECT: reduced weight of structure.
