Abstract:
A heat exchanger apparatus comprising:a condenser having:a condensation part for cooling and condensing gaseous refrigerant by heat exchange with cooling air passing through the condenser;a receiver for removing liquid refrigerant from the refrigerant condensed by the condensation part; anda supercooling part for supercooling the liquid refrigerant from the receiver by heat exchange with the cooling air; andan auxiliary radiator for cooling an exothermic component, the auxiliary radiator being disposed on a cooling air upstream side of the condenser and facing the condenser except at least a part of the supercooling part, wherein:the supercooling part has a height B1 in a direction perpendicular to a flowing direction in which the refrigerant flows; andthe auxiliary radiator has a part facing the supercooling part, the part of the auxiliary radiator having a height A1, a ratio of which relative to the height B1 is equal to or less than 0.85.
