摘要： A sheet metal fan exhibiting special utility as a radiator fan for an internal combustion engine. A spider carries the blades on its arms, the arms each having a radially extending stiffening rib in opposed relation to a complementary rib in its blade to thereby form a tube where the stiffening ribs are radially coextensive. The stiffening rib on each blade intersects a continuous, blade stiffening channel.
