Oilcooler

摘要

The present invention relates to an oil cooler, more particularly relates to an oil cooler provided with communicating portions (160) formed therein to allow oil flowed therein to be uniformly distributed and being capable of promoting a generation of turbulent flow of oil to enhance a heat-exchanging performance of oil and cooling water. An oil cooler according to the present invention comprises a pair of inlet/outlet boss portions (110) spaced from each other at a predetermined distance; an inlet pipe (120) and an outlet pipe (130) coupled to the inlet/outlet boss portions, respectively; and tubes (140) coupled to the inlet/outlet boss portions (110) through both ends thereof to form an oil flow passage. Here, wherein the tubes are disposed in parallel and in a multi-stage and the tube is formed with a communicating portion (160) for communicating the tube with the neighboring tube at an area between the inlet pipe and the outlet pipe to allow oil to be flowed therebetween.
