A condenser has an outlet side region close to an outlet for discharging refrigerant from the condenser. The outlet side region does not face auxiliary radiator, which is disposed on a cooling air upstream side of the condenser. Accordingly, low temperature cooling air that does not pass through the auxiliary radiator can flow into the outlet side region of the condenser in which the refrigerant is lowered most. As a result, a difference in temperature between the refrigerant and the cooling air at the outlet side region becomes large. This prevents deterioration of cooling capacity of the condenser.

[ What is claimed is:] [4.] A heat exchanger apparatus comprising:a condenser having a core portion including a tube extending in a refrigerant flow direction in which refrigerant flows, an inlet tank connected to the core portion and having an inlet for conducting the refrigerant into the tube, and an outlet tank connected to the core portion and having an outlet for discharging the refrigerant from the tube, the condenser being for cooling the refrigerant flowing in the tube by heat exchange with cooling air flowing outside of the tube;an auxiliary radiator for cooling an exothermic component, the auxiliary radiator being disposed on a cooling air upstream side of the condenser; anda receiver communicating with the core portion of the condenser for separating the refrigerant cooled in the core portion into gaseous refrigerant and liquid refrigerant; wherein:the core portion of the condenser is divided along the refrigerant flow direction into a first region and a second region closer to the outlet than the first region;only the first region faces the auxiliary radiator;the first region has a width approximately equal to a width of the auxiliary radiator in the refrigerant flow direction;the core portion of the condenser has a condensation part for condensing the refrigerant between the inlet tank and the receiver and a supercooling part for supercooling the liquid refrigerant separated by the receiver between the receiver and the outlet tank; andthe second region is at least part of the supercooling part;the supercooling part has a height B1 in a height direction perpendicular to the refrigerant flow direction;the auxiliary radiator has a part facing the supercooling part with a height A1 in the height direction; anda ratio of the height A1 relative to the height B1 is equal to or less than 0.85.
