<P>PROBLEM TO BE SOLVED: To provide a vehicle heat exchanger capable of simultaneously performing a warming-up function and a cooling function of a working fluid depending on a temperature of an inflow working fluid varying according to a traveling state of a vehicle and initial starting conditions. <P>SOLUTION: A vehicle heat exchanger includes a heat dissipating part formed by laminating a plurality of plates 112 such that first, second and third working fluids flow into first, second and third connecting passages 114 respectively and that the first, second and third working fluids circulate without being mixed with one another; a branch part 120 connecting an inflow hole 116 for allowing one of the first, second and third working fluids to flow in, to a discharge hole 118 for discharging one working fluid, and allowing the one working fluid to bypass the heat dissipating part by the temperature of the one working fluid; and a valve unit 130 mounted into a position corresponding to the inflow hole 116 and allowing the one working fluid to flow selectively into the heat dissipating part 110 or the branch part 120 by the temperature of the one working fluid flowing into the inflow hole. <P>COPYRIGHT: (C)2013,JPO&INPIT |
