摘要： A condenser for use in an automotive air conditioning system including inlet and outlet union elements is disclosed. The condenser comprises a plurality of flat pipes for conducting refrigerant and a plurality of corrugated fins fixedly sandwiched between the flat pipes. First and second header pipes are fixedly and hermetically connected to the flat pipes, thereby communicatingly connecting the flat pipes to the interior of the header pipes. Inlet and outlet union elements for connecting the condenser to the other elements of the air conditioning system are formed in one body and connected to one of the first and second header pipes, thereby reducing the fraction of union element/header pipe junctions which are defective by reducing the number of union element/header pipe junctions.

摘要： A heat exchanger, such as a condenser, for use in an automobile air conditioning system comprises a plurality of flat tubes for conducting the refrigerant and a plurality of corrugated outer fins fixedly sandwiched between the flat tubes. First and second header pipes are fixedly and hermetically connected to the flat tubes and thereby communicate with the interior of the tubes. Each of the flat tubes includes a flat tube member and a corrugated inner fin. The corrugated inner fin includes a plurality of ridges which extend along the width of the flat tube member. The adjacent ridges are fixedly connected to upper and lower inner surfaces of the flat tube member so as to define a plurality of lateral hollow regions in an interior hollow portion of the flat tube member. A plurality of openings are formed in each of surfaces of the corrugated inner fin defined between the adjacent ridges so as to laterally disperse the flow of the refrigerant when the refrigerant flows through the interior hollow space of the flat tube. As a result, the heat exchange efficiency of the condenser is sufficiently improved while preventing expansion of the flat tube members.

摘要： A heat exchanger includes a pair of header pipes, tubes disposed between the header pipes, and radiation fins provided along the tubes. Each of the header pipes has a plurality of connection holes for the tubes. Each of the header pipes is formed by bending a longitudinal flat plate in the form of a pipe and connecting the side edge portions of the bent plate to each other. The side edge portions of the bent longitudinal plate have connecting portions which are connected to each other with a junction area larger than the cross-sectional area defined by the thickness and length of each header pipe at a position other than the side edge portions. The connection holes are processed before the longitudinal flat plate is bent, and therefore, can be easily and precisely formed at desired positions. The manufacture of the heat exchanger can be simplified and the cost for the manufacture can be reduced. The connection strength of the side edge portions can be increased by the larger connection area of the connecting portions. The strength of the header pipe can be maintained over a long period of time.

摘要： A condenser, for use in automotive air conditioning systems, including a first header, a second header, a plurality of parallel flat plate pipes arranged between the first and second headers, and corrugated fins between the flat plate pipes for contacting the flat surfaces thereof. A second union joint on the second header introduces refrigerant into the second header. A first union joint on the first header discharges refrigerant to a refrigeration circuit. The first union joint includes a union portion for connecting the first union joint with the refrigeration circuit, a fixed portion with a receiving surface which is fitted on the outer peripheral surface of the first header, and a pipe which is connected to the union portion. The pipe extends downwardly within the first header to the bottom of the first header, and thus, the first union joint discharging liquid refrigerant can be disposed anywhere on the first header.

摘要： A heat exchanger including a first and second header is disclosed. The headers are linked in fluid communication by a plurality of elongated fluid tubes. In a first embodiment, the first and second headers are integrally formed as a single pipe having a partition wall extending radially across. Left and right intermediate headers are disposed laterally of the single pipe. Two groups of fluid tubes link the first header to a lower portion of the intermediate headers, and two additional groups of fluid tubes link the intermediate headers to an upper portion of the second header. In a second embodiment, the first and second headers are disposed in a spaced parallel arrangement and are approximately half the length of the left and right intermediate headers with which they are linked at an upper portion of the intermediate headers by fluid tubes. The lower parts of the intermediate headers are linked directly by a third group of tubes to complete the fluid circuit of the heat exchanger.

摘要： A heat exchanger having a flat tube with a plurality of fluid passageways therein, header pipes connected to opposite ends of the flat tube and inlet and outlet tubes connected to the header pipes, respectively. The inlet and outlet tubes are inserted and fitted into the corresponding ones of the header pipes and formed with axial slits in the inserted end portions. The opposite ends of the flat tube extend into header pipes through axial slits in the outer surfaces thereof and are fitted into the axial slits of the inlet and outlet tubes inserted therein. Thus, the inlet tube and the outlet tube are reliably maintained in their desired orientation. The header pipes are made of aluminum brazing sheet and, therefore, are brazed to the aluminum flat tube and the inlet and outlet aluminum tubes.
