Abstract
A heat exchanger for a vehicle is mounted in a vehicle having a power train through which an engine coolant, an engine oil and a transmission oil flow and in which a flow rate of the engine oil and a flow rate of the transmission oil are different from each other. A first flow passage for causing the engine coolant to flow, a second flow passage for causing the engine oil to flow, and a third flow passage for causing the transmission oil to flow are formed through lamination of a plurality of plates. The heat exchanger includes a region where the first flow passage is adjacent only to that one of the second flow passage and the third flow passage through which a fluid flows at lower flow rate.
