Problems solved by technology

However, in the oil cooler including the inner fins having the above-mentioned structure, the oil flow is similar to laminar flow, thus degrading the heat exchange performance due to the reduction of the oil resistance.

Abstract

The present invention relates to an oil cooler, more particularly relates to an oil cooler provided with communicating portions 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 spaced from each other at a predetermined distance; an inlet pipe and an outlet pipe coupled to the inlet / outlet boss portions, respectively; and tubes 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 communicatingportion 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.

Description

technical field [0001] The present invention relates to an oil cooler, and more particularly to an oil cooler provided with communication portions formed therein to allow the oil flowing therein to be evenly distributed and capable of promoting oil turbulence to Improve the heat exchange performance of oil and cooling water. Background technique [0002] A radiator is a device used to prevent the temperature of the engine from rising above a predetermined value. The radiator is a heat exchange device used to circulate the cooling water in the engine while circulating the high-temperature cooling water through the radiator through the water pump to absorb the heat generated by combustion in the engine and transfer the heat contained in the high-temperature cooling water to the outside, thereby preventing the engine from overheating and maintaining optimal driving conditions. [0003] Meanwhile, an oil cooler is provided in an automatic transmission vehicle to cool the engin...
