Abstract

An oil cooler has a tube (103d) disposed in a cooling water passage (103c) and defining an oil passage therein, an oil side inner (102c) fin brazed to an inside wall of the tube (103d) in the oil passage, and a water side inner fin (102d) brazed to an outside wall of the tube (103d) in the cooling water passage. The thickness Tw of the water side inner fin (102d) is thicker than the thickness To of the oil side inner fin (102c). The water side and oil side inner fins (102c, 102d) are corrugated fins.
