A cooling structure includes a cooling pass meandering around an advance direction of high-temperature combustion gas and formed on a structure body. The cooling pass has a flow-in pass formed inside the structure body for a cooling air, at least one rectilinear pass arranged at an interval with respect to the axial direction, and a fold-back pass communicating end portions of the flow-in pass and the rectilinear pass or alternately communicating the end portions of the rectilinear passes.
L'invention concerne une structure de refroidissement qui comprend un canal de refroidissement serpentant autour du sens de progression d'un gaz de combustion à haute température et formé sur un corps de structure. Le canal de refroidissement comporte un canal d'entrée formé à l'intérieur du corps de structure, pour de l'air de refroidissement, au moins un canal rectiligne disposé à une certaine distance par rapport à la direction axiale et un canal de repli faisant communiquer les parties terminales du canal d'entrée et du canal rectiligne ou en alternance les parties terminales des canaux rectilignes.
