摘要
PROBLEM TO BE SOLVED: To provide a grating radiating fin block which can avoid reduction in radiation efficiency caused by the increased thickness of a fin wall, even when the full length of the block in a mold drawing direction is long, and which also can facilitate manufacture of a movable core mold. ;SOLUTION: The radiating fin block includes grating-shaped radiating fins which has a plurality of sheets of straight fins 12 projected outwardly of a heat receiving surface 11, and also has a grating partition wall 13 interconnecting the adjacent straight fins 12. In this case, a comb-shaped radiating fin part 14 having only the straight fins 12 without the partition wall 13 is formed in the middle of the grating radiating fin in a mold drawing direction, and grating radiating fin parts 15 are provided on both sides of the fin part 14.;COPYRIGHT: (C)1999,JPO
