It is partitioned by (54), and an inlet pipe (55) for the refrigerant inlet and an outlet pipe (56) are connected in communication with each other at a predetermined position of the headers (52) (52) so that the inlet pipe (55 ) Flows through the tubes (51) ... in a meandering manner, and while flowing through the tubes (51) ..., exchanges heat with the air that flows through the condenser in the front-rear direction. It is condensed and liquefied and discharged through the outlet pipe (56).

Although (52) is an indispensable component for forming the refrigerant circuit, it does not contribute to heat exchange, so to speak, it becomes a dead space portion. Therefore, where it is desired to make this as narrow as possible in the area,
The header (52) is joined with the tube (51) by inserting the end of the tube (51) into the tube insertion hole (57) formed in the peripheral side surface of the header (52) as described above. The diameter D of (52) is
It must be designed to have a large size so that the end of 1) can be inserted, and in the configuration where the header (52) has a circular cross-section, the header (52) is inevitably in the longitudinal direction of the tube (51). The maximum width becomes large, so that the dead space portion that does not contribute to heat exchange becomes large. For example, tubes (51)
When the width t is 16 mm, the outer diameter D of the header (52) is, for example, 20 mm. A dead space with a width of 20 mm and a total width of 40 mm is generated. Specifically, in this heat exchanger, the proportion of dead space is 1
It may be 3.3%.

When the one having a diameter of 24 mm is used as the header (52), the outer diameter D is, for example, 24 mm, and therefore, the width of one side by the headers (52) (52) is 24 mm at both ends of the tube (51). A dead space having a width of 48 mm is generated, and in such a heat exchanger, the dead space ratio may reach 16%.

る危険性もある。On the other hand, the tube insertion holes (57) of the header (52) facilitate insertion of the tubes (51), and the brazing area between the header (52) and the tubes (51). Burring processing (59) (59) may be performed on the peripheral portion of the tube insertion hole formed in the arc-shaped side wall portion (for example, for the purpose of increasing the size). Since the punch is forcibly inserted into the hole 57), the burring parts (59) (59) formed by the punch are formed in the width of the tube insertion hole (57) as shown in FIG. Although it is formed large in the central part in the direction, the burring part obtained by forming becomes smaller toward the end side, so that the brazing area between the header (52) and the tube (51) .. Tube (51 Gradually decreases toward the end side of the width direction, the risk of causing leakage by involuntary bonding failure is.

In the heat exchanger of the type in which the burring portion is formed in the peripheral portion of the tube insertion hole of the header, the burring portion can be formed large even toward the tube width direction end side. It is an object of the present invention to provide a condenser having a structure that can be used.

される。Means for Solving the Problems The above-mentioned problems are provided with a plurality of flat tubes for heat exchange and at least one hollow header, and the hollow header is provided on one side in the circumferential direction of a peripheral side wall thereof. A plurality of circumferential slit-shaped tube insertion holes are provided at predetermined intervals along the longitudinal direction, the end of the flat tube is inserted and arranged in the header through the tube insertion holes, and the flat tube and the header are integrally joined. In the condensed condenser, in the hollow header, the peripheral side wall portion on the side opposite to the peripheral side wall portion on the tube connection side in the circumferential direction is formed into an arc-shaped wall portion, and the peripheral side wall portion on the tube connection side is formed. It is formed on a flattened wall portion that is flatter than the arcuate wall portion, and the arcuate wall portion and the flattened wall portion are smoothly continuous in the curved curved connecting wall portion in the circumferential direction. Be connected It is solved by the condenser, wherein the door.

ダーとしての耐圧性能を十分に備えている。That is, the peripheral side wall on the side opposite to the peripheral side wall on the tube connection side is formed into an arcuate wall, and the arcuate wall and the flat wall are bent in the circumferential direction. Smoothly and continuously connected at the connecting wall, and
In the flat wall portion, the flat tube is joined and integrated with the flat wall portion, so that the reinforcing effect is obtained. Therefore, the condenser has sufficient pressure resistance as a header.

積が大きく確保されるようになる。Moreover, in the hollow header, the peripheral side wall portion on the tube connection side is formed as a flattened wall portion which is flatter than the arcuate wall portion, so that the tube can be formed in accordance with the width of the flattened tube. Even if the maximum width of the header in the width direction is increased, the maximum width of the header in the tube insertion direction does not increase to such an extent. Therefore, it is possible to prevent the dead space that does not contribute to heat exchange from becoming large due to the presence of the header, and to secure a large core area effective for heat exchange in the determined space.

定されているのがよい。In this case, the maximum width of the header in the tube width direction is set to be longer than the width of the tube in the range of 1 to 5 mm on the header outer peripheral surface side, and the radius of curvature of the arcuate wall portion is , On the outer peripheral surface side thereof, is set to half the maximum width of the header in the tube width direction, and the flat wall portion has, on the outer peripheral surface side, a radius of curvature in the range of 1 to 3 times the tube width, It is preferable that the curved connecting wall portion is formed in a bulging flat shape and has a radius of curvature of 5 to 7 mm on the outer peripheral surface side.

偏平状壁部の領域範囲が減少してヘッダーの耐圧性能の
低下を招くことにもなる。If the maximum width of the header in the tube width direction is larger than the width of the tube by less than 1 mm, the wall thickness of the header must be made very thin, and pressure resistance cannot be ensured. If the maximum width of the header in the tube width direction is equal to or smaller than the width of the tube, the tube cannot be inserted into the tube insertion hole of the header. Further, if the maximum width of the header in the tube width direction is larger than the width of the tube by more than 5 mm, the arcuate wall portion unnecessarily protrudes greatly in the tube longitudinal direction, and a dead space that does not contribute to heat exchange is created. Not only is the size increased, but the area range of the flat wall portion reinforced by joining with the tube is reduced, and the pressure resistance performance of the header is deteriorated.

の低下を招きやすくなる。If the radius of curvature of the flat wall portion is smaller than 1 times the tube width, the radius of curvature becomes too small, and the meaning of flattening is apt to be lost. If the size is more than twice as large, the pressure resistance performance of the header is likely to be deteriorated although it is reinforced by the joint with the tube.

洩れの発生が確実に防止される。In each of the above constructions, it is preferable that a burring portion is provided at the peripheral edge of the tube insertion hole provided in the hollow header. As a result, the burring process for the tube insertion hole is performed on the flat wall portion that is flatter than the arcuate wall portion.
The burring portion becomes larger not only at the widthwise central portion of the tube insertion hole but also toward the end portion side. Therefore, the brazing area between the header and the tube is reduced in the widthwise direction of the tube. Since it is sufficiently secured toward the end portion side of, the occurrence of leakage due to defective joint can be reliably prevented.
