<p>A multistage gaseous and liquid phase separation type condenser (30) has a pair of headers (32,34) disposed in parallel with each other, and a plurality of flat tubes (36) each connected to the headers (32,34) at opposite ends thereof and corrugated fins interposed between adjacent flat tubes (36). Each header (32,34) is divided by baffles (42) into four chambers (50,52,54,56,58,60,72,74). The second header (34) has a receiver (40) and chambers of the second header (34) have communication passageways for placing the chambers (56,58,60,74) of the second header (34) in flow communication with the receiver (40). The first header (32) has an inlet pipe connected to a middle chamber (50) thereof so as to form an inlet path and an outlet pipe connected to a lower chamber (54) thereof. While the refrigerant flows through the paths defined by a plurality of flat tubes (36), a first separation of gaseous and liquid phases of the refrigerant occurs within the second header (34) so that the separated gaseous refrigerant is recondensed flowing through an upper path above the inlet path and introduced into the receiver (40) via the communication passageway (44,46,48), whereas the separated liquid refrigerant is introduced into the receiver (40). A second separation of gaseous and liquid phases of the refrigerant occurs within the receiver (40) in connection with a certain amount of the liquid refrigerant stored in the receiver (40). The liquid refrigerant in the receiver (40) is communicated with the lower path via a lower communication passageway formed in the lower chamber (60) of the second header (34). <IMAGE></p> |
