特徴とするオイルクーラ。[Scope of Claim for Utility Model Registration] A bottom flange on the oil supply side, a top flange that also serves as a cooling water intake/discharge and oil outlet, a heat exchange core unit stacked in multiple stages between each flange, and each core unit. A pair of cooling water passages are formed in the top and communicate with each other, and a pair of oil passages are opened in each of the core units and communicated between the core units, and one of the cooling water passages is connected to the top. The other cooling water passage communicates with a cooling water inlet formed in the flange, the other cooling water passage communicates with a cooling water outlet formed in the top flange, and the lowest oil passage communicates with an oil inlet formed in the bottom flange. In addition, in the oil cooler in which the oil passage on the uppermost stage communicates with the oil outlet provided in the top flange: The diameter of each of the cooling water passages is set to the minimum diameter in the core unit on the uppermost stage, and the diameter of the core unit on the lower stage is made larger than the diameter on the upper stage. An oil cooler characterized in that the diameter of the oil passage is set to be the maximum diameter in the lowermost core unit, and the diameter of the upper core unit is smaller than that of the lower core unit.
