A MULTISTAGE GAS AND LIQUID PHASE SEPARATION TYPE CONDENSER

Abstract

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.

This invention relates to a heat exchanger, and more particularly to a multi separation type condender of the gaseous and liquid phases of the refrigerant. Both the first and second header 13 and 14 are porvided with battles to define a plurality of paths each defined by a plurality of flat tubes 11. Fig. 1 shows four paths formed and the number of paths varies with increase or decrease of the baffles. In the multiflow type condenser, the refrigerant flows in zigzag fashion between the inlet pipe 13 and the outlet pipe 16.. The refrigerant introduced into the condenser 10 provided with the 11 is another object of the present invention to provide a multistage gas and liquid phase separation type condenser in which by providing one of a pair of headers with a receiver and the other with a refrigerant of the refrigerant passed through said first path to flow therethrough ; a first separation of gaseous and liquid phases of the i liquid phase separation type condenser according to further another embodiment of the present invention. introducing the the refrigerant gas from an external compressor into the condenser 30 is connected to the middle chamber 50 of the first header 32, and an outlet header 34, and then, exists the condenser 30 through the outlet pipe 66 toward an external climate control system. Arrows show the direction of flow of the through the paths is not introduced into the receiver 40 as much as possible. Otherwise. each communication passageways may be sized in numeral. For chamber 50 of the second header 34. The gaseous refrigerant is the condenser 30 flows through the inlet path PI, and then, the first receiver 40. An inlet pipe 64 for introducing the refrigerant gas from an external compressor into the condenser 30 is connected to the middle chamber In operation of condenser 30, compressed refrigerant gas from an again, and enough small size of the lower communication passageway 46 by which rapid flow of the refrigerant from the outlet path P4 toward the outlet schematic view illustrating flow of the refrigerant in the condenser of FIG. 11. The outlet path P4 toward the outlet pipe 66 and to prevent the refrigerant of the oulet path P4 from being swept along with the liquid refrigrant exiling through the outlet pipe 6(5. Further the second header may have a desicent/filter disposed in the lower chamber 60 thereof so as to prevent the gaseous refrigerant from exiling the condenser 30 through the outlet pipe 66. FIG. 13 is an entire cross-sectional view showing a desiccant installed in the condenser, wherein this embodiment is based on the embodiment depicted in FIG. 6 except the bypass conduit. Preferably, the desiecant 86 is arranged to cover an inlet port of an outlet pipe 66. Otherwise, the desiccant 86 may be disposed in the lower chamber 60 of the second header 34. Such filtering means removes impurities such as water, dust and gaseous refrigerant contained in the refrigerant, except the liquid refrigerant. We Claim, 1. A multistage gas and liquid phase separation type condenser, comprising • a second separation of gaseous and liquid phases of the r('triH(M"nnt iftlnKluced into said receiver occurring in connection with a certain ninnuut of the licjiiid refriRcranl existing within said receiver. 11. The condenser of claim 1, wherein said lower communication SAID RECEIVER VIW AN UPPER communication passageway provided between an 19. The condensder of claim 14 further comprising filtering means disposed within said receiver for removing impurities from the refrigerant a refrigerant outlet provided with said first header or said !-'8. The condenser of claim 25, wherein said third path is made up of two paths each defined by a plurality of tubes by diving a lower 34. A multistage gas an liquid phase separation type condenser substantially as herein described with reference to the accompanying drawings.
