Abstract: PROBLEM TO BE SOLVED: To provide a cooling device and method for a wall for provide a convection cooling inside the wall. SOLUTION: This cooling circuit 22 having one or more inlet openings 40 and one or more outlet openings 44 is arranged between a first wall part and a second wall part. The inlet opening 40 provides a cooling air flow passage led to the cooling circuit 22, while the outlet opening 44 provides a cooling air passage led out of the cooling circuit 22. The cooling circuit 22 includes a plurality of first pedestals 34 extended between the first and second wall parts. The first pedestals are arranged in at least one line 48. In one preferred embodiment, the first pedestals are separated from each other by inner-line spacings 50 in any line 48, while the adjacent pedestals in the adjacent lines are spaced from separated from each other by across-line spacings 52. The inner-line spacing 50 exceeds the across-like spacing 52.

Abstract: A cooling circuit 22 disposed between a first wall portion 36 and a second wall portion 38 of a wall 24 for use in a gas turbine engine, comprises one or more inlet apertures 40, and one or more exit apertures 44. The inlet aperture(s) 40 provides a cooling airflow path into the cooling circuit 22 and the exit aperture(s) 44 provides a cooling airflow path out of the cooling circuit 22. The cooling circuit includes a plurality of first pedestals 34 extending between the first wall portion 36 and the second wall portion 38. The first pedestals 34 arc arranged in one or more rows 48. Preferably the distance between the pedestals 34 in a row 48 is greater than the distance between the rows 48. Also, preferably the passage 57, 90 between the pedestals 34 define a pair of throats 62, 64 with a diffuser 60 in between. The exit apertures 44 are preferably defined between a plurality of second and third pedestals 66, 68 with mating geometries.
