Receiver and refrigerant cycle system

A refrigerant cycle system comprising:

• a compressor for compressing refrigerant;
• a condenser having a condensing portion for cooling and condensing refrigerant discharged from said compressor, and a super-cooling portion for super-cooling liquid refrigerant;
• and
• a receiver for separating refrigerant from said condensing portion of said condenser into gas refrigerant and liquid refrigerant, and for storing liquid refrigerant, wherein:
• said receiver has
• a first refrigerant inlet from which refrigerant having passed through said condensing portion is introduced into an upper side within said receiver,
• a second refrigerant inlet from which refrigerant having passed through said condensing portion is introduced into a lower side within said receiver, said second. refrigerant inlet being provided at a position lower than said first refrigerant inlet, and
• a refrigerant outlet from which liquid refrigerant stored within said receiver flows toward said super-cooling portion of said condenser.

A receiver-integrated condenser comprising:

• a core portion having a plurality of tubes through which refrigerant flows in a horizontal direction;
• a first header tank extending in a vertical direction perpendicular to the vertical 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 gas refrigerant and liquid refrigerant, and for receiving liquid refrigerant;
• and
• a separator disposed within said second header tank in such a manner that an inner space of said second header tank is partitioned into upper and lower spaces in the vertical direction, wherein:
• said receiving unit is integrated with said second header tank in such a manner that a communication passage extending over both sides of said separator in the vertical direction is defined by said receiving unit and said second header tank;
• said second header tank communicates with said communication passage in such a manner that refrigerant condensed in said core portion flows into said communication passage through said lower space of said second header tank;
• and
• said communication passage communicates with said receiving unit in such a manner that refrigerant in said communication passage flows into said receiving unit from upper and lower sides.

• 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 gas refrigerant and liquid refrigerant, and for receiving liquid refrigerant;
• and
• first and second separators disposed within said second header tank in such a manner that an inner space of said second header tank is partitioned into upper, intermediate and lower spaces in the vertical direction, wherein:
• said receiving unit is integrated with said second header tank in such a manner that a communication passage extending over both upper and intermediate spaces in the vertical direction is defined by said receiving unit and said second header tank;
• said second header tank communicates with said communication passage in such a manner that refrigerant condensed in said core portion flows into said communication passage through said intermediate space of said second header tank between said first and second separators;
• said core portion includes a condensing portion at an upper side for condensing refrigerant, and a super-cooling portion at a lower side for super-cooling refrigerant flowing from said receiving unit;
• and
• said communication passage communicates with said receiving unit in such a manner that refrigerant in said communication passage flows into said receiving unit from upper and lower sides, and refrigerant in said receiving unit flows into said super-cooling portion through said lower space of said second header tank.
