A multistage gaseous and liquid phase separation type condenser has a pair of headers disposed in parallel with each other, and a plurality of flat tubes each connected to the headers at opposite ends thereof and corrugated fins interposed between adjacent flat tubes. Each header is divided by baffles into four chambers. The second header has a receiver and chambers of the second header have communication passageways for placing the chambers of the second header in flow communication with the receiver. The first header has an inlet pipe connected to a middle chamber thereof so as to form an inlet path and an outlet pipe connected to a lower chamber thereof. While the refrigerant flows through the paths defined by a plurality of flat tubes, a first separation of gaseous and liquid phases of the refrigerant occurs within the second header so that the separated gaseous refrigerant is recondensed flowing through an upper path above the inlet path and introduced into the receiver via the communication passageway, whereas the separated liquid refrigerant is introduced into the receiver. A second separation of gaseous and liquid phases of the refrigerant occurs within the receiver in connection with a certain amount of the liquid refrigerant stored in the receiver. The liquid refrigerant in the receiver is communicated with the lower path via a lower communication passageway formed in the lower chamber of the second header.

[ What is claimed is:] [1.] A multistage gas and liquid phase separation type condenser, comprising:a first header having at least three chambers;a second header having at least two chambers and disposed in parallel with said first header;a plurality of tubes each connected to said headers at opposite ends thereof;a plurality of fins each fin disposed between adjacent tubes;a receiver provided with one of the headers;a refrigerant inlet provided with a middle chamber of said first header;a refrigerant outlet provided with one of said headers or said receiver;the refrigerant being introduced through said inlet and exiting the condenser through said outlet;the refrigerant flowing through a first path defined through a plurality of tubes, a second path located above said first path and defined through a plurality of tubes for recondensing a gaseous refrigerant of the refrigerant passed through said first path, and a third path located below said first path and defined through a plurality of tubes for allowing a liquid refrigerant of the refrigerant passed through said first path to flow therethrough;a first separation of gaseous and liquid phases of the condensation-progressed refrigerant passing through said first path occurring within said second header so that the separated gaseous refrigerant is recondensed flowing through said second path and thereafter introduced into said receiver via an upper communication passageway provided between an upper chamber of the header with said receiver and said receiver, while the separated liquid refrigerant flows through said third path toward said outlet;a fluid communication between said receiver and the header with said receiver being made via a lower communication passageway provided between a lower chamber of the header with said receiver and said receiver; anda second separation of gaseous and liquid phases of the refrigerant introduced into said receiver occurring in connection with a certain amount of the liquid refrigerant existing within said receiver.
