FIG. 4 is a view taken along a line IV-IV in FIG. 2, and FIG. 5 is a view taken along a line VV in FIG.

As shown in FIG.
An upper header 13 and a lower header 14 are provided on the outer peripheral surface of the tank body 12, and a jacket 15 having a number of cooling medium passages (jacket portions) 16 is provided between the upper header 13 and the lower header 14. .
The upper end of the jacket portion 16 communicates with the inside of the upper header 13 through the opening of the upper header 13, and the jacket portion 16
The lower end communicates with the inside of the lower header 14 through the opening 14a of the lower header 14. Cooling medium (for example, brine) in the upper header 13 (or the lower header 14)
Is supplied, and the cooling medium flows through the inside of the jacket portion 16 and is discharged from the lower header 14 (or the upper header 13). The inside of the tank body 12 is cooled by the cooling medium flowing through the inside of the jacket portion 16.

The jacket 15 is formed by joining the corrugated plate member 21 to the outer periphery of the tank body 12. The corrugated plate member 21 is formed with three semi-cylindrical mountain portions 22 extending in the vertical direction of the tank body 12, and the mountain portions 22 form the jacket portion 16. Also,
Band-shaped flat portions 23 are formed at a total of four places between and on both sides of the three chevron portions 22 of the corrugated plate member 21. The four band-shaped flat portions 23 are connected to the tank body 12 by electric resistance welding.
The belt-shaped flat portion 23 and the tank body 12
A weld 24 is formed on the outer peripheral surface of the upper surface of the upper surface. The welds 24 at the upper and lower ends of the band-shaped flat portion 23 are liquid-tight welds so that the cooling medium does not leak.

Upper header 13 Upper and lower headers 1
4 The lower part in contact with the tank body 12 is joined by continuous fillet welding, and the joints between the upper header 13 and the lower header 14 and the jacket 15 are also joined by fillet welding. Further, the lower portion of the upper header 13 and the upper portion of the lower header 14 where there is no jacket 15 are joined to the tank body 12 by fillet welding. That is, the upper header 13 and the lower header 14 of the jacket 15 are fixed not through the tank body 12 but directly through the upper and lower ends of the belt-like flat portion 23.

When the jacket 15 is provided on the tank body 12 when the beer tank 11 is constructed, the corrugated plate member 21
Are joined to the outer peripheral surface of the tank body 12 by electric resistance welding. Thereby, the jacket 15 having three jacket portions 16 is provided on the tank body 12 by four continuous weldings. Therefore, the number of welds 24 for one jacket 16 can be reduced.

That is, in the illustrated jacket 15, three jacket portions 16 are fixed to the tank main body 12 by continuous welding at four locations. On the other hand, in the conventional beer tank shown in FIGS. 10 to 12, three jacket portions 6 are fixed to the tank body 1 in order to have the same passage cross section and the same cooling capacity mechanically. Although it is necessary, in order to fix the three jacket portions 6 to the tank body 1, six continuous welded portions 5 are required.

Therefore, in the beer tank 11 in the illustrated example ,
While maintaining the same cooling capacity as before, the jacket 15
In this case, the number of welding steps can be reduced. In addition, in the beer tank 11 of the present embodiment, a defect occurs in the welded portion 24 between the chevron portions 22 and the jacket portion 6
Even if the spaces are connected, the cooling medium does not leak to the outside.
For this reason, the welding portion 24 between the angled portions 22 does not need to be continuous welding, and the number of welding steps can be further reduced as intermittent welding.

In the illustrated example , three corrugated portions 22 are provided on the corrugated plate member 21 so that the jacket portion 16 is formed at three places. However, the present invention is not limited to this. The tank in the illustrated example can be applied to a tank other than the beer tank 11 as long as the tank has a passage for the cooling medium provided in the tank body.

[0017] The implementation embodiment of the present invention will be described with reference to FIGS. 6-9.

[0023]

According to the present invention, there is provided a tank provided with a jacket provided with a large number of passages for circulating a cooling medium on an outer peripheral portion of a tank body. Since the passage for flowing the cooling medium is formed by the angled portion by joining to the outer peripheral portion of the main body, the number of joints to one angled portion is reduced as compared with the case where the individual passages are joined to the tank body, It is possible to reduce the number of joining steps. Further, even if a defect occurs at the joint between the mountain portions, the cooling medium does not flow into the adjacent mountain portions and leak to the outside. As a result, the number of work steps can be reduced and the reliability can be increased without lowering the cooling capacity.

In the tank according to the present invention, the corrugated plate member has a band-shaped flat portion joined to the outer peripheral portion of the tank body between the plurality of chevron portions, and a notch is formed at a longitudinal end of the band-shaped flat portion. By forming the portion, the periphery of the notch portion is fixed to the outer peripheral portion of the tank body, so that there is no effect even if the joining member protrudes at the end of the band-shaped flat portion, and the corrugated plate member and other members using the notch portion Can be directly joined to the tank body. As a result, workability and strength are improved.
