Claim Text:
1. A heat exchanger for a vehicle, comprising: a heat radiating portion provided with first and second connecting lines formed alternately by stacking a plurality of plates, and receiving first and second operating fluids respectively into the first and second connecting lines, the first and second operating fluids heat-exchanging with each other during passing through the first and second connecting lines; and a bifurcating portion connecting an inflow hole for flowing one operating fluid of the first and second operating fluids with an exhaust hole for exhausting the one operating fluid, wherein the bifurcating portion is adapted for the one operating fluid to bypass the heat radiating portion according to a temperature of the one operating fluid, and mounted at an exterior of the heat radiating portion, wherein the first operating fluid flows into the heat radiating portion through a first inflow hole and flows out from the heat radiating portion through a first exhaust hole, and the first inflow hole is connected to the first exhaust hole through the first connecting line, wherein the second operating fluid flows into the heat radiating portion through a second inflow hole and flows out from the heat radiating portion through a second exhaust hole, and the second inflow hole is connected to the second exhaust hole through the second connecting line, wherein the first and second inflow holes are formed at both sides of a surface of the heat radiating portion along a length direction of the heat radiating portion, and the first and second exhaust holes are distanced from the first and second inflow holes and are formed at the both sides of the surface of the heat radiating portion along the length direction of the heat radiating portion, wherein the valve unit comprises
