[Purpose of invention]

[Technical Field to which the Invention belongs and Prior Art in the Field]

The present invention relates to a method of fixing by ¾ element (La) of the element CI S and refrigerant pipe rule welding.

LA CIator can also be used as a heat exchanger for cooling Hocheongdo IfeQI, OT oil for transformers, air conditioners for automobiles, residential air conditioners, chillers for industrial cold 0H, coolant (or cooling oil) for precision machinery or equipment. In fact, width a has been used in the field.

The structure of the La CJ EI is that the allen 50 is formed at regular intervals between the first refrigerant pipe 60 and the low 12 cold 0H pipe 70 as shown. Conventional Technique: The cold 0H, which is hot as the appliance is cooled, flows from the »M cold pipe 60 to the first 50 refrigerant pipe 70 passing through the ele- ment 50, or the second cold 0H. In the pipe (70) flows to the ¾ first refrigerant pipe (60), the air flows through the element (50) while the temperature is lowered, and then enters the equipment again to perform a cooling action to perform a cooling action It is summer. The element 50, which acts as a heat sink in the la α EK100) is the first refrigerant

Location to the outside)). The welded portion W3 is formed such that the arc-shaped end portion T1 exposed inwardly of the second semicircular pipe 20a is integral with the second semicircular pipe 20a.

≥ step (mo;

The third semi-circular pipe 30 is joined with the second semi-circular pipe 20a to form a welded portion W2, which is completed as a final step for the second semi-circular pipe 20a and the third semi-circular pipe 30 to be integrated. It is characterized by.

Alternative Paper (Article 26) Hereinafter, the operation of the present invention will be described by creating the drawings.

First look at the first embodiment of the present invention. 3, 4, and 3 are spaced portions 54 through which cold 0H can flow from side to side with reference to the central seam (363111) welded portion 53, and seams around the edges of the day are seamed. ) Step (i) is performed to fabricate the element 10 having the arcuate end T formed as shown in Figs. At this time, it should be noted that the conventional expansion pulley part 51 is omitted for welding and fixing the first cold 0H pipe 60 and the second refrigerant pipe 70.

Next, at the same time as the manufacturing step (i) of the element 00, as shown in Fig. 5, an incision S (22) into which the edge (A) of the edge seam welding portion is inserted into the left and right sides is formed in large size. An arcuate end (T) of the Heleent 10 can be inserted into the length 21 at regular intervals, and a third semi-circular pipe ( Step (Π) is performed to fabricate the first semi-circular pipe 20 in which the chamfer portion 23 for welding engagement with 30 is formed.

6, 9, the chamfer portion 31 for welding engagement with the first semicircular pipe 20 is formed at the left and right shaft ends in the longitudinal direction and has the same dimensions and the same length as the ¾11 semicircular pipe 20. Branches are made in the third semicircular pipe 30 step (iii) of manufacturing.

Here, the first semi-circular pipe 20 may be formed in half of the existing circularly produced pipe to form the sphere S (21) and the cut-out S (22). After the ball ¾ (21) and the incision S (22) by pressing

Alternative Paper (Article 26) It can also be used after forming into a semi-circular shape. Meanwhile. Third semicircular pipe

(30) can also be used by cutting the existing circular pipe rule half or by forming a steel plate semi-circle. And it is natural that the mother © base portions 23 and 31 are formed separately. The diameter, thickness, and length of the first semicircular pipe 20 and the third semicircular pipe 30 are determined by design.

9 and 3 show that the first semi-circular pipes 20 are flushed at the upper and lower ends of the element 10, respectively, in the drawing of the present invention at the lower end of the element 10. FIG. Note that the state in which the first semicircular pipe 20 is fitted is not shown. Subsequently, the arc-shaped end T of the element 10 is infiltrated into the lifejacket 21 and works at the same time as poop! The edge A of the edge junction 11 of the 3I cement 10 is to be infiltrated into the incision hum 22 and then arced to be exposed inside the first semicircular pipe 20 as shown in FIGS. 9 and 13. Step (iiii) is performed to form a weld in the ¾11 semicircular pipe 20 so that the end T and the end portion A of the edge seam weld are integral with the first semicircular pipe 20.

In other words, this step corresponds to the most important part of the present invention GI, the inside of the first semi-circular pipe 20, as shown in Figure 9 Alley 2! Since the edge A of the long-terminal junction 11 is exposed by about 2 to 3 mm, the welded portion W1 can be formed in a state in which there is no room 6H, which is the most effective. «It is possible to weld correctly.

Due to this feature, the tongue 21 and incision § (22) of the first semicircular pipe 20

Alternative Paper (Article 26) The welding work can be performed quickly and accurately with all the elements (10) to be welded in place.

Step (iiii) of forming such a weld portion W1 is completed and joined with the third semi-circular pipe 30 cone bottom 11 semi-circular pipe 20 as shown in FIG. 10 to form a weld portion W2. When the last step of forming the first semicircular pipe 20 and the third semicircular pipe 30 is performed, a radiator is manufactured by the new construction method according to the first embodiment of the present invention. In addition, a second embodiment of the present invention is considered.

In the second embodiment of the present invention, the structure of the upper and lower portions of the element 10a is slightly different and the structure of the second semi-circular pipe 20a is slightly different as compared with the first oil. The part is the same as that of 1st implementation oil.

In view of this, a space 54 through which the refrigerant can be called is formed on the left and right of the center seam weld portion 53S, and the seam weld portion 52 is formed on the entire edge. The boiling step of the edge joining end 11a is performed to produce an element 10a in which a cutting surface N is formed and an arcuate end T1 is formed.

On the other hand, in the low 12 semi-circular pipe 20a, there is a difference in which only the sphere S 21a into which the arc-shaped end portion T1 is infiltrated is formed, as shown in FIG. Therefore, as shown in Figs. 11 and 12, only the arc-shaped end portion T1 of the element 10a is infiltrated into the sphere S (21a) of the second semi-circular pipe 20a for welding and fixing, and the edge joint end 11a. Cutting edge (N) of the low 12 semicircular

Alternative Paper (Article 26) It is in a state where only * is in contact with the outer surface of the pipe 20a.

In this second embodiment, as shown in Fig. 11, only the arc-shaped end portion T1 of the element 10a is infiltrated into the life 21a of the low 12 semi-circular pipe 20a, and then the weld portion W3 as in the first embodiment. ), The element 10a and the second semicircular pipe 20a may be united in ratio. Subsequently, as shown in FIG. 12, the third semicircular pipe 30 is combined with the second semicircular pipe 20a in the same manner as in the first embodiment I, and the welded portion W2 is formed to complete the lower edge. The welding work in this second embodiment can also be done very ideally as described in the first embodiment. As a result of fabricating LA I EI through the method of the present invention as described above, it was found that 99.9¾ of the bad wind generation ratio caused by welding failure was extinguished, and the quality of the CH wind was almost perfect. The time required for producing one was reduced by 60% and the weight of the radiator Θ was increased by 5% due to the loss of the expansion flange 51.

Alternative Paper (Article 26) 【Effects of the Invention】

As described above, the novel method of the present invention not only realizes the generation of bad winds due to welding defects, which have been the most frequent in the production of radiators, but also substantially improves and increases productivity and productivity. E. It has a very useful effect of solving problems and assertions at once.
