An oil cooler comprises an inner water pipe, an outer oil pipe, a strainer pipe sleeved between oil pipe and water pipe, and a connector mechanism at either end of oil cooler and including a hollow cylindrical connector having a passage coupled to water pipe, a ring groove, a plurality of first O-ring grooves, an abutment groove adjacent ring groove, and an oil channel connected to strainer pipe, a ring fitted in ring groove, and a plurality of first O-rings fitted in O-ring grooves. The invention adopts a snapping mechanism to secure oil pipe to the cylindrical connector, thus eliminating potential crack in welded portion of pipes and end connectors and leakage. Moreover, it is easy to assemble, durable, and high in cooling efficiency.
