HEAT EXCHANGER FOR A VEHICLE, CAPABLE OF IMPROVING RESPONSIBILITY OF VALVE OPENING OPERATION ACCORDING TO TEMPERATURE OF A WORKING FLUID

摘要

PURPOSE: A heat exchanger for a vehicle is provided to simultaneously perform a warm up function and a cooling function of a working fluid by using temperature of the working fluid flowing according to an initial start condition or a driving state of the vehicle when the working fluid controls the temperature inside through mutual heat exchange.;CONSTITUTION: A heat exchanger comprises a radiation unit(110) and a branch unit(120). The radiation unit alternatively forms different connection fluid paths inside by laminating a plurality of plates(112). Different working fluids individually flow in the radiation unit and passes through the each connection fluid path in order to perform mutual heat exchange. A connection fluid path is divided so that the supplied working fluids are individually circulated. The branch unit mutually connects an inlet hole(116) and a discharge hole(118) in order to discharge or induce the working fluid to the radiation unit. The branch unit is mounted on the outside of the radiation unit so that the working fluid does not pass through the radiation unit according to the temperature of the working fluid.;COPYRIGHT KIPO 2013
