ている。 A flat liquid passage pipe 20 in which a plurality of refrigerant channels 21 are formed as shown in FIG.
The meandering portion 2 is meandered until it reaches
A corrugated fin 30 is interposed between the liquid passage pipes 20 in 4, and a branch pipe 40 is provided at the inlet portion 22.
In the evaporator 10 in which the outlet portion 23 is provided with a merging pipe 41 in communication with each other, conventionally, as shown in FIG.

を有していた。 However, in such an evaporator 10, even if the condensed water that has condensed on the surface of the corrugated fin 30 or the liquid passage pipe 20 can be discharged through the grooves 25 and 26, the grooves 25 and 26 are connected to the liquid passage pipe 20. Since it is formed by scraping the surface of the outer wall 20a of
Deep grooves could not be formed and condensed water could not be sufficiently discharged. Further, in order to drain water sufficiently, the outer wall 20a must be formed thickly, resulting in a problem of high cost. Further, the grooves 25 and 26 are provided not only in the meandering part 24 of the liquid passage pipe 20 but also in the inlet part 22 and the outlet part 23 (not shown), and communicate with the inlet part 22 and the outlet part 23. The junctions 40a and 40b of the branch pipe 40 and the merging pipe 41 must also have the same complicated shape, which of course causes problems in processing and assembly. 41, the melted brazing filler metal flows down into the liquid passage pipe 20 through the grooves 25 and 26, which tends to result in poor bonding, and the corrosion resistance of the liquid passage pipe 20 also deteriorates due to the flowing brazing filler metal. There was a problem.

である。以下、本考案を図面について説明する。 In view of the above-mentioned problems found in conventional products, the present invention is designed to effectively discharge condensed water that has condensed on the liquid passage pipe or corrugated fin, and to connect the liquid passage pipe, branch pipe, and merging pipe. It is an object of the present invention to provide an evaporator that can easily and reliably perform the following steps. Hereinafter, the present invention will be explained with reference to the drawings.

２３には形成されていない。 3a and 3b show an embodiment of the present invention, and the same components as those of the conventional example are designated by the same reference numerals. That is, 10 is an evaporator, 20 is a flat liquid passage pipe that meanderes (meandering portion 24) from a refrigerant inlet portion 22 at one end to a refrigerant outlet portion 23 at the other end, and 21
30 is a plurality of refrigerant channels formed independently and parallel to each other inside the liquid passage pipe 20; 30 is the liquid passage pipe 20;
Corrugated fins are interposed between the corrugated fins, 40 is a refrigerant branch pipe provided at the refrigerant inlet 22 of the liquid passage pipe 20, and 41 is a refrigerant outlet 2 of the liquid passage pipe 20.
This is a refrigerant merging pipe provided at 3. Reference numeral 50 denotes a plurality of drainage grooves extending in the vertical direction provided in the meandering portion 24 of the liquid passage pipe 20, and
The outer wall 21a of No. 1 is deeply depressed. However, the deep groove 50 is not formed at the inlet section 22 and outlet section 23 of the liquid passage pipe 20.

に行なわれる。 Since the evaporator 10 according to the present invention is configured as described above, the air flowing between the corrugated fins 30 has heat removed by the refrigerant flowing through the refrigerant flow path 21 of the liquid passage pipe 20. Moisture in the air condenses on the surfaces of the liquid passage pipe 20 and the corrugated fin 30, but the condensed water is quickly discharged through the deep groove 50 without staying or scattering. In addition, the inlet portion 22 and the outlet portion 2 of the liquid passage pipe 20
Since the deep groove 50 is not provided in No. 3,
Joint parts 40a and 4 of the branch pipe 40 and the merge pipe 41
1a, it is sufficient to simply provide an elongated rectangular hole similar to the inlet section 22 and outlet section 23;
The brazing work of the 0 and the merging pipe 41 can be easily and reliably performed.

業が確実に行なわれることとなる。 Note that when the inlet portion 22 and outlet portion 23 of the liquid passage pipe 20 are formed to be longer in the vertical direction than the joint parts 40a and 41a of the branch pipe 40 and the merging pipe 41, respectively, the joint parts 40a and 41a are formed in the meandering direction. The brazing work can be performed reliably without joining to the deep groove 50 of the portion 24.

易かつ確実となるという利点をも有する。 As explained above, according to the present invention, a flat liquid passage pipe in which a plurality of refrigerant channels are formed is made to meander from the refrigerant inlet at one end to the refrigerant outlet at the other end, and the liquid passes through the meandering part. In an evaporator in which a corrugated fin is interposed between the pipes, a branch pipe is connected to the inlet part, and a merging pipe is connected to the outlet part, the inlet part and the outlet part of the liquid passage pipe are connected to each other. Since a plurality of drainage grooves formed by sinking the outer wall of the refrigerant flow path are provided in the meandering part except for It has the advantage of preventing an increase in ventilation resistance due to stagnation and improving the heat exchange rate.Also, since the shapes of the inlet and outlet of the liquid passage pipe are not complicated, it is easy to avoid the joints of the branch pipe and the convergence pipe. It also has the advantage that it does not require complicated machining, and furthermore, the work of assembling it to the liquid passage pipe and the work of brazing it are easy and reliable.
