In a receiver-integrated condenser, a super-cooling portion for cooling liquid refrigerant from a receiving unit is disposed between first and second condensing portions in a core portion in a vertical direction. Therefore, in an engine-idling, even when high-temperature air having passed through the receiver-integrated condenser is introduced again toward an upstream air side of the receiver-integrated condenser through a lower side of the receiver-integrated condenser, the high-temperature air is not introduced toward the arrangement position of said super-cooling portion, because the super-cooling portion is positioned at an upper side from the second condensing portion. Thus, super-cooling performance of refrigerant in the super-cooling portion of the core portion is prevented from being decreased even in the engine idling.

1. A receiver-integrated condenser for a refrigerant cycle, comprising:a core portion having a plurality of tubes through which refrigerant flows in a horizontal direction, said core portion being disposed to define a condensing member for condensing super-heating gas refrigerant from a compressor of the refrigerant cycle and a super-cooling member for super-cooling liquid refrigerant; a first header tank extending in a vertical direction perpendicular to the horizontal direction, said first header tank being connected to each one side end of said tubes to communicate with said tubes; a second header tank extending in the vertical direction, said second header tank being connected to each the other side end of said tubes to communicate with said tubes; a receiving unit for separating refrigerant from said condensing member into gas refrigerant and liquid refrigerant and for storing liquid refrigerant therein, said receiving unit being integrated with said second header tank; and a wall member for defining a first communication passage through which refrigerant from said condensing member is introduced toward said receiving unit, and a second communication passage through which liquid refrigerant in said receiving unit is introduced toward said super-cooling member, said first and second communication passages being arranged in parallel to extend in the vertical direction along said second header tank and said receiving unit between said second header tank and said receiving unit, wherein at least a part of said condensing member is disposed at a lower side of said super-cooling member, in said core portion.
