ABSTRACT:
The present invention effectively cools members with a small amount of cooling air. Turbulence promotor ribs are formed so that cooling fluid along a wall flows from a center of the wall to both end portions of the wall. A highly enhanced thermal conducting effect, namely high cooling heat transfer coefficient, can be obtained, and it is possible to cool members effectively with the small amount of cooling air.
