On the other hand, a typical car condenser has a traditional fin and tube structure, and has one header tank to which the inlet / outlet pipes are fastened to both sides, and the other header tank to which the receiver dryer tank is connected in parallel.

One header tank and the other header tank are arranged in parallel so that a plurality of slits formed while maintaining a predetermined distance along the axial direction on the circumferential surface of each tank face each other.

As the tubes are inserted into the slits and fixed by solder, one header tank and the other header tank penetrate through the plurality of tubes, and pins, which are zigzag metal thin plates, are disposed between the fixed tubes. .

As shown in FIG. 1, a header tank and a receiver dryer tank for an automobile condenser according to the related art are provided with a plurality of connection portions 3 and a plurality of connection portions 3 to transfer heat exchange fluid between the header tank 1 and the receiver dryer tank 2. The support part 4 is fastened.

The connection part 3 has a tubular shape which is crimped or the intermediate part protrudes and the inside penetrates along the axial direction.

The upper end of the connection part 3 is formed with a contact end 3a on the header tank 1 side, and the contact end part 3b on the receiver dryer tank 2 side is formed at the lower end of the connection part 3.

This connecting portion 3 serves to protect the inner hollow shaft 5 used as a means for flowing the heat exchange fluid in a state supported on the outer circumferential surface of each of the header tank 1 and the receiver dryer tank 2. .

The outer circumferential surfaces at both ends of the inner hollow shaft 5 are inserted into the connection holes formed in the header tank 1 and the receiver dryer tank 2, respectively, and are fixed by the solders 6 and 7 of the manual fixing method.

The connection part 3 according to the prior art is manufactured to have a tubular shape penetrated by sheet metal processing, and then the cutting part 3a and 3b are formed in contact with the header tank 1 and the receiver dryer tank 2. There is a disadvantage in that processing is required, and complicated separate processing such as processing such that wrinkles or intermediate portions are protruded is required.

However, the manufacturing process of the conventional connection part 3 is not only very difficult and complicated, but also the manufacturing cost is high, and in particular, the structural strength which can be relatively connected when supporting and supporting the header tank 1 and the receiver dryer tank 2 is relatively high. There is a weak disadvantage.

Because the connection part 3 itself is formed by sheet metal processing that is not directly fixed to the header tank 1 and the receiver dryer tank 2, it is not directly fused to the header tank 1 and the receiver dryer tank 2. Because.

In addition, when the connecting portion 3 is inserted so as to surround the outer side of the inner hollow shaft 5 by the fastening relationship with the inner hollow shaft 5, other contact portions except for the solders 6 and 7 (for example, It is difficult or impossible to form solder for reinforcement in the places indicated by 8 and 9, and finally, the inner hollow shaft 5 is firmly connected to the connection hole of the header tank 1 and the receiver dryer tank 2. Hard to fix.

As a result, the connection part 3 and the inner hollow shaft 5 according to the prior art are structures that cannot increase rigidity or maintain strong durability in the fastening structure between the header tank 1 and the receiver dryer tank 2. In addition, it is pointed out as a weak spot that can be damaged by the vibration of the car engine, the impact during driving, etc., there is a disadvantage that the assembly process is cumbersome with the complicated manufacturing process.

In order to overcome this problem, the receiver dryer tank 20 for automobile condenser of the prior art is integrally formed with the connection portion 30 or the support portion 40.

In the prior art, in order to integrally form the connecting portion 30 or the supporting portion 40 in the receiver dryer tank 20, an extruded hollow base material formed by integrally projecting the bar-shaped protrusion portion 21 to the outer circumferential surface thereof ( 20 ') was used.

However, the conventional receiver dryer tank 20 for automobile condenser also requires a minimum weight and solid durability due to the characteristics that are mounted on the vehicle.

Therefore, since the bar-shaped protrusion 21 of the extruded hollow base material 20 'is repeatedly machined to form a desired receiver dryer tank shape, the receiver dryer tank 20 itself is difficult and complicated to have a disadvantage. .

That is, when manufacturing the conventional receiver dryer tank 20, the cutting portion 22, 23, 24, 25 having a smooth shape in the portion between the connecting portion 30 or the support portion 40 or both end portions thereof. There are manufacturing difficulties in which corresponding mechanical processing is required.

In addition, the cutting areas 22, 23, 24, 25 are stepped areas 29, which are relatively thicker than the outer circumferential diameter of the tank body 28, even if the cutting areas 22, 23, 24, 25 are cut to have a smooth surface at a complicated machining cost and high cost. Since this is expressed, there is a disadvantage in that it is not beautiful in appearance.

In addition, the thickness of the tank body 28 is thinner than that of the stepped region 29, so that the tank body 28 has a thickness structure which is not uniform as a whole. The heat transfer is unbalanced at least as much as the cutting regions 22, 23, 24, 25. The disadvantage is that the product quality is relatively poor.

Afterwards, the upper surface of the connection portion 30 and the support portion 40 should be formed with a spherical surface corresponding to the outer circumference of the header tank. For this purpose, the tank body 28 is mounted and fixed to a fixed tool (eg, a vise, etc.). Since a mechanical load is applied to form a spherical surface in a state, there is a fear that the surface of the tank body 28 may be scratched or deformed.

Further, thereafter, various mechanical processes such as various holes must be formed in the connection part 30 or the support part 40 through the drilling process, and mechanical and physical loads are required during the manufacture of the receiver dryer tank 20. As it is directly transmitted, quality control of the receiver dryer tank 20 itself is difficult and mass production efficiency is low.
