<P>PROBLEM TO BE SOLVED: To provide a heat exchanger for a vehicle having advantages of simultaneously warming up and cooling working fluid, and also having further advantages of improving fuel economy, heating performance and reducing the number of assembling man-hours of the vehicle. <P>SOLUTION: The heat exchanger for the vehicle includes: a heat radiating unit provided with first and second connecting lines formed alternately by stacking a plurality of plates, receiving first and second working fluids into the first and second connecting lines, and performing heat exchange mutually while passing the first and second connecting lines; a bifurcating unit connecting an inflow hole for flowing one working fluid of the first and second working fluids with an exhaust hole for exhausting the one working fluid, and adapted for the one working fluid to bypass the heat radiating unit according to a temperature of the one working fluid; and a valve unit mounted corresponding to the inflow hole and adapted to flow the one working fluid selectively to the heat radiating unit or the bifurcating unit according to the temperature of the one working fluid flowing in the inflow hole. <P>COPYRIGHT: (C)2013,JPO&INPIT |
