Abstract
A heat exchanger may include a heat radiating portion provided with first, second, and third connecting lines formed in a predetermined sequence by stacking a plurality of plates, and receiving first, second, and third operating fluids respectively into the first, second, and third connecting lines. The first, second, and third operating fluids exchange heat with each other but are not mixed with each other. The heat exchanger may include a bifurcating portion connecting an inflow hole for flowing one operating fluid of the first, second, and third operating fluids with an exhaust hole and adapted for the one operating fluid to bypass the heat radiating portion according to a temperature of the one operating fluid, and a valve unit adapted to flow the one operating fluid selectively into the heat radiating or bifurcating portions according to a temperature of the one operating fluid flowing into the inflow hole.
