とのできる熱交換器を提供することを目的とする。However, in the heat exchanger having the conventional structure, the partition plate 5 and the inner wall of the header 1 are perpendicular to each other, and when the heat transfer medium collides with the partition plate 5, a turbulent flow is generated. Since the flow resistance is increased due to the state, the fluid does not flow smoothly into the flat tube 2. In addition, the same can be said because the heat transfer medium flowing out of the flat tube 2 into the header 1 also collides with the inner wall of the header 1 and becomes turbulent. As a result, the pressure loss of the heat transfer medium increases and the flow velocity decreases, so that heat exchange between the heat transfer medium and the air passing outside the flat tube 3 cannot be performed efficiently. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a heat exchanger capable of smoothly flowing a heat transfer medium between a tubular member and a flat tube to enhance thermal efficiency.

る。According to the present invention, in order to achieve the above object, notches are formed at predetermined intervals in a longitudinal direction in a pair of cylindrical members arranged side by side at predetermined intervals, while flat tubes and fins are alternately laminated. In the heat exchanger, both ends of each flat tube are inserted into the cutout holes of the tubular member and brazed, and the internal space of the tubular member is divided longitudinally by a partition plate. An insertion hole is formed in the cylindrical member, and the internal space of the cylindrical member is divided in the longitudinal direction by inserting the partition plate through the insertion hole. The flow direction changing wall surfaces facing the respective internal spaces are formed in a curved shape along the flow direction of the heat transfer medium between the tubular member and the flat tube near the partition plate.

FIG. 1 shows a part of a condenser which is a heat exchanger of a vehicle air conditioner. This capacitor is the same as the conventional example except for the shape of the partition plate 10 and the header 1 in the vicinity thereof, and the corresponding parts are denoted by the same reference numerals. That is, the edge of the insertion hole 11 formed in the outer wall surface of the header 1 is press-formed inward, so that the flow direction changing wall surface 12 is formed on the inner surface thereof as shown in FIG. Have been. This flow direction changing wall surface 12
Has a smooth curved surface shape so that the heat transfer medium flowing from above the header 1 smoothly flows into the flat tube 2 and the heat transfer medium flows out from the flat tube 2 into the header 1 smoothly. Further, the partition plate 10 which is inserted into the insertion hole and brazed is obtained by cutting a part of a circular plate-like body, and an arc portion abuts on an inner peripheral surface of the header 1 to divide the internal space, The cut portion fits into the insertion hole and closes it.

る。In the condenser, the heat transfer medium flowing into the header 1 flows along the flow direction changing wall surface 12 near the partition plate 10 and flows into the flat tube 2. The heat transfer medium flowing out of the flat tube 3 into the header 1 also flows along the flow direction changing wall surface 12 and flows out into the header 1. For this reason, the heat transfer medium does not become turbulent and does not easily receive flow resistance. Therefore, pressure loss is reduced, and the heat transfer medium flows smoothly while meandering through the header 1 and the flat tube 2, and flows through the fins 4 with air. Heat exchange is efficiently performed.
