FIELD: mechanical engineering; heat release and film protection of moving parts. ^ SUBSTANCE: proposed microcontour to provide passing of cooling gas flow through part contains at least one inlet hole to let in cooling gas, channel of contour laid from said inlet hole to provide flowing of cooling gas and at least one outlet hole in end part of said channel of contour to provided coming out of cooling gas from said channel of contour through this hole. Channel of contour is formed by relative putting on and connecting of group of alternating spiral contours. ^ EFFECT: improved efficiency of cooling, decreased possibility of choking of microcontour, improved manufacturability. ^ 6 cl, 9 dwg |
