    • The evaporator according to the present invention is equipped with a core (1) including an upper side and lower side heat exchanging tube groups P1 and P2 arranged front and rear and an upper side and lower side header members (10) and (50) disposed at the upper and lower end of the core (1). The inside of the upper header member is divided front and rear to form an inlet-side tank (11) and an outlet-side tank (12). On end of each tube (6) constituting the upstream-side tube group P1 is connected to the inlet-side tank (11), while the other end is connected to the lower header member (50). On end of each tube (7) constituting the downstream-side tube group P2 is connected to the outlet-side tank (12), while the other end is connected to the lower header member (50). The refrigerant flowed into the inlet-side tank (11) is introduced into the outlet-side tank (12) by passing through the upstream-side tube group P1, the lower header member (50) and the downstream-side tube group P2. On the other hand, the refrigerant passing through both the heat exchanging tube groups P1 and P2 evaporates by exchanging heat with ambient air A. accordingly, it becomes possible to improve the heat exchange performance and to decrease the thickness.

    • The invention relates to heat exchangers for use in motor vehicles or for industrial use, for example, to heat exchangers for use as evaporators, condensers, oil coolers, intercoolers, heater cores, etc. The invention provides a heat exchanger comprising pairs of plates with each plate of the pair having formed on one side thereof a peripheral ridge, central ridge and channel dividing U-shaped ridges which are formed by forging or cutting. Each pair of plates are fitted together and joined, with channel recesses thereof opposed to each other to form a flat tube and a plurality of U-shaped divided fluid passageways in a U-shaped fluid channel inside the tube. Each pair of adjacent flat tubes are joined by spectacle-shaped header members interposed between the upper ends of the tubes and each comprising a front and a rear fluid passing tube portion and a connecting portion therebetween to provide a front and a rear header in communication with the upper ends of the flat tubes. The flat tubes have a reduced front-to-rear width, diminished wall thickness (thinner layers) and increased heat transfer efficiency to provide a heat exchanger which achieves a higher heat transfer efficiency and greatly improved heat exchange performance.
