<P>PROBLEM TO BE SOLVED: To provide a member improving heat transfer performance by reducing a circulation region on the downstream side of a rib. <P>SOLUTION: The member having a cooling passage 7c formed therein and having opposed partition walls 6b, 6c between which cooling air is made to flow to cool a base material includes: a first heat transfer promoting rib 25a inclined to the downstream direction of a medium while extending from a portion in the vicinity of the middle between the opposed partition walls 6b, 6c to one partition wall 6c side; and a second heat transfer promoting rib 25b inclined to the downstream direction of the cooling air while extending from a portion in the vicinity of the middle between the opposed partition walls 6b, 6c to the other partition wall 6b side. Slits 70a, 70b penetrating through the upstream side and the downstream side of the cooling passage 7c are formed in the first heat transfer promoting rib 25a and the second heat transfer promoting rib 25b, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
