The shape and structure are determined depending on the header (5) of the receiver body (1) and the receiver (2), and do not particularly depend on the structure on the vehicle body side. Therefore, there is no trouble that many kinds of holding members are manufactured and prepared in relation to the vehicle body as in the related art.

In the manufacturing process of the condenser body (1), the liquid receiver holding member (3) holds the headers (5) (5), the tubes (4)..., The fins (6). When combined with the header (5), it is assembled to the header (5) at the same time, and is integrally joined to the outer periphery of the header (5) by collective brazing.

At this time, as shown in FIG. 4, the liquid receiver holding member (3) and the header (5) are properly positioned and a brazed joint part having no leakage and excellent sealing properties is formed. A short pipe member (31) is passed between the refrigerant inlet (27) of the brazing contact part (23) of the receiver holding member (3) and the refrigerant outlet hole (10) of the header (5). In such an assembled state, they are collectively brazed. The batch brazing of the receiver holding member (3) is performed as follows.
As the hollow header (5), a pipe in which an aluminum brazing sheet is wound in a side-to-side butt shape is used, and a brazing material clad on the outer peripheral surface of the pipe can be used. As described above, the receiver holding member (3)
Since the inner surface of the brazing abutment (23) is formed to conform to the outer shape of the header (5), special troublesome processing such as forming a dent on the outer surface of the header (5) is required. No need to apply. In particular, the receiver holding member (3)
Is made of a sliced product of an extruded aluminum material, so that the brazing contact portion (23) having a shape along the outer peripheral shape of the header (5) can be easily manufactured.

The liquid receiver (2) is combined with the condenser body (1) in the following manner to constitute a liquid receiver integrated condenser. That is, as shown in FIG. 1, the liquid receiver (2) is turned upward, and the flange connection surface (16) of the lower end surface is
The receiver holding member (3) is supported on the flange connecting surface (25) on the flange main body (24). At that time, the circular convex refrigerant outlet (29) on the side of the receiver holding member (3) is nested into the refrigerant inlet (17) formed by the circular hole on the lower surface of the receiver (2). . By this nested fitting, the liquid receiver (2) can be accurately positioned and arranged on the liquid receiver holding member (3). The O-ring (32)
The sealing property between them is ensured. Then, a bolt (33) is screwed from below, and the receiver holder (3) and the receiver (2) are flange-connected. Thereby, the liquid receiver (2) is firmly and firmly held at the lower end side of the condenser body (1). At the same time, the receiver (2) and the condenser body (1) are connected to the internal passage (2) of the receiver holder (3).
6) is connected to the communication state. Therefore, the conventional piping for connecting and connecting the liquid receiver (2) and the condenser body (1) becomes unnecessary. The receiver holder (3) is previously joined to the condenser header (5) by brazing and integrated. When the receiver (2) is attached, the receiver (2) is attached to the condenser header (5). It is only necessary to flange-connect to the receiver holding member (3), and the work of attaching the receiver (2) to the condenser body (1) can be performed efficiently.

The upper end of the liquid receiver (2) is further held by the condenser body (1) as follows. That is, a stay (34) is provided on the header (5) of the condenser body (1) in a laterally protruding state at the upper end of the liquid receiver (2). This stay (34) is manufactured by slicing an aluminum extruded die into predetermined length units, and as shown in FIG. 5, has one end along the outer peripheral portion of the header (5) in the circumferential direction. Abutment portion for brazing (35), which abuts on the outer periphery of the header (5) and is joined to the header (5) by batch brazing It is integrated. Also, stays (3
The other end of 4) is formed with a keyhole-shaped concave portion (36) that is open toward the distal end, as shown in FIG.
A pin (22) erected on the upper surface of the tank cover (14) of the liquid receiver (2) fits into the keyhole-shaped recess (36) via a rubber mount (37) as a vibration isolator. Are held together. The liquid receiver (2) is firmly held on the upper and lower sides of the condenser body (1) as described above.

In the condenser integrated with the liquid receiver, the condenser main body (1) may be simply attached to the vehicle body by using an attachment member such as a bracket when the condenser is mounted on the vehicle body. Thereby, the liquid receiver (2) is also incorporated into the vehicle body. Piping work for connecting the liquid receiver (2) and the condenser body (1) is unnecessary. Therefore, the installation work on the vehicle body side can be performed efficiently.

In the condenser integrated with the receiver, the refrigerant condensed in the condenser body (1) is supplied to the lower end of the header (5) of the condenser body (1) as shown by an arrow in FIG. Through the refrigerant outlet hole (10) of the side container, the internal passage (26) of the receiver holder (3), and the refrigerant inlet (17) of the receiver (2). (12), rises in the inflow pipe (12), passes through the strainer (13) from the upper end of the inflow pipe (12), and is blown out into the tank (11). At the bottom side of the tank (11), the gas refrigerant is gas-liquid separated upward. Then, only the liquid refrigerant is sent out of the tank (11) through the refrigerant outlet union (20) on the side surface of the lower end of the tank (11), and the original function of the liquid receiver is properly exhibited.

The refrigerant outlet (20) of the liquid receiver (2) is provided on the side surface of the lower end of the tank (11), and the liquid refrigerant in the tank (11) is directly supplied to the refrigerant outlet union (20). It is sent out through
The hanging outflow pipe is unnecessary, and the inflow pipe (12) standing upright on the inner bottom surface of the tank allows the refrigerant from the condenser body (1) to pass directly through the refrigerant inlet (17) on the lower surface of the tank. Since the refrigerant is blown up as it is and is not blown up by the pressure in the tank where gas and liquid coexist in a separated state, the blowing height of the refrigerant becomes very high. The height of 12) can be increased, and a slim and smart liquid receiver (2) having a high tank height as shown in the figure can be realized. In particular, since the upper end of the inflow pipe (12) is engaged with and held by the tank upper wall (14), the standing stability of the inflow pipe (12) is improved. The length can be increased, and a slim and smart liquid receiver (2) having a high tank height can be realized. Therefore, by arranging the receiver (2) in parallel along the header (5) of the condenser body (1), the receiver (2) is integrally provided with the condenser body (1). Thus, it is possible to realize a compact integrated structure that does not cause difficulty in the arrangement space.

The tank (11) includes an aluminum forging and a bottomed cylindrical tank body (21) integrally forged including a partition wall (43), and the upper end opening of the tank body (21) is closed with a lid (14). Others are the same as the above embodiment.

FIG. 10 shows another modification of the liquid receiver. It is of the same partition type as in FIG.
In 1), the upper and lower ends of an aluminum cylindrical tank body (21) integrally extruded including the partition wall (43) are closed with lids (14) and (40). Others are the same as the above embodiment.

FIG. 11 shows a modification of the mounting structure of the upper end side of the liquid receiver (2) to the header (5). Reference numeral (50) denotes a clip, which is formed of a synthetic resin integrally molded product of nylon 66 or the like having a U-shape in a plan view and having flexibility. This clip (50) has outwardly projecting claws (51) at both ends.
(51) is integrally formed. On the other hand, the stay (34) is formed with a concave portion (36) opened at the tip end thereof, and inside the concave portion (36), the claw (5) of the clip (50) is formed.
