の問題があった。In the prior art, the baffle plate arranged at the position closest to the U-bending side of the U-shaped heat transfer tube must have a notch at the lower end for turning the cooled body. However, since the U-shaped heat transfer tube cannot be fixed due to this notch, the U-shaped part that is disengaged by the notch between this baffle plate and the next baffle plate.
An auxiliary plate for fixing the heat transfer tube is required. By installing this auxiliary plate, the flow velocity of the object to be cooled is increased between the auxiliary plate and the baffle plate arranged at the position closest to the U-bending side, and the U portion of the U-shaped heat transfer tube is formed by the shell and the side plate. The enclosed partition room has a structure in which the fluid to be cooled does not flow inside the U-shaped heat transfer tube and the fluid to be cooled easily flows through the gap between the U-shaped heat transfer tube on the outside and the side plate. There was a problem of abnormal sound generation.

が固定される。To achieve the above object, the present invention provides a mounting hole in which a U-shaped heat transfer tube is arranged by one baffle plate arranged closest to the U-bent portion of the U-shaped heat transfer tube. By shifting the position from the center of the baffle plate by several mm from the positions in the other baffle plates, the pressing force from the baffle plate acts on the heat transfer tube on the U side, and the U-shaped heat transfer tube is fixed.

解消を図ることができる。In the water cooler having n baffle plates, the heat transfer tube mounting hole position of the nth baffle plate closest to the U side is displaced by several mm from the position of the other n-1 baffle plates. . As a result, when the baffle plate is wound around the body plate, the n-th and (n-1) th baffle plates exert a pressing force in a direction in which the heat transfer tubes alternate. Further, since there is no gap between the heat transfer tube and the mounting hole in the baffle plate, the occurrence of abnormal vibration can be eliminated.

The U-shaped heat transfer tube 5 inside the portion surrounded by the first baffle plate 3 and the shell 4 and the straight tube portions 5a, 6a of the outer U-shaped heat transfer tube 6 rise around the first baffle plate 3 and the first sheet at the upper end. The notched portion of the baffle plate 3 is turned, and the space between the first baffle plate 3 and the second baffle plate 7 is lowered again. This is repeated up to the upper end of the (n-1) th baffle plate 8, the (n-1) th upper end is turned down, and the lower end of the nth baffle plate 9 is turned, Finally, it rises around the U-bent portion 6b of the outer U-shaped heat transfer tube 6 surrounded by the n-th baffle plate 9 and the side plate 10 and flows out from the water cooler through the cooled fluid connection pipe 11. . At this time, the distance from the center line of the heat transfer tube mounting hole in the baffle is indicated by d as shown in FIG. According to the present invention, the distance from the first baffle plate 3 to the baffle plate 8 is d
1 and the distance in the nth baffle plate 9 is d
Shift a few millimeters from 1 to obtain d 2 (<d 1 ).

なり、異常振動音を発生することもない。According to the present invention, the position of the mounting hole in which the U-shaped heat transfer tubes of the one baffle plate arranged near the U-side portion of the U-shaped heat transfer tube are arranged is changed to a plurality of other baffles. Since the baffle plate is displaced by several mm from the position of the hole in the plate, when the baffle plate is wound by the body plate, the baffle plate exerts a force to hold down the heat transfer tube, and there is no gap between the heat transfer tube and the baffle plate. For this reason, even if the U-shaped heat transfer tube is not fixed in the turn-out notch at the lower end of the n-th baffle plate, vibration is reduced and abnormal vibration noise is not generated.
