能が低下するという不具合があった。According to the above-mentioned prior art, in the U portion partitioned by the baffle plate of the U-shaped heat transfer tube, the cross-sectional area of the water flow passage between the inner U-shaped heat transfer tube and the outer U-shaped heat transfer tube is small and the flow resistance is increased. On the other hand, in the portion surrounded by the outer U-shaped heat transfer tube, the shell and the plate, the water flow path cross-sectional area is large and the flow path resistance is small. Therefore, a large amount of water flows through the outer U-shaped heat transfer tube having a small flow path resistance and the portion surrounded by the shell and the plate. Conversely, between the inner U-shaped heat transfer tube and the outer U-shaped heat transfer tube, the flow passage cross-sectional area is small and the flow passage resistance is large, so that it is difficult for water to flow. In this prior art, no consideration is given to the point of uniformly flowing water in the U portion, so that the amount of heat exchange between the refrigerant and water in the inner U-shaped heat transfer tube portion is small, and the heat transfer performance is reduced. Was.

内側と外側の伝熱管に水が均一に流れるようになる。The final baffle plate arranged at the position closest to the U-shape of the U-shaped heat transfer tube is partially cutout-shaped, and a plurality of holes are arranged at the center corresponding to the bent portion of the heat transfer tube. As a result, the water that has flowed to the center of the final baffle plate is divided into a cut-out portion and a plurality of holes, and the respective water amounts are substantially the same. Therefore,
The water flows uniformly through the inner and outer heat transfer tubes.
さらに、最終バッフルプレートの複数の穴の並び方向

にできる。Cold water entering from the water inlet 3 is supplied from the chamber surrounded by the tube plate 13 and the baffle plate 6 to the baffle plate 6.
Then, the water flows through the chamber surrounded by the baffle plate 7 to the center of the water chamber 9 surrounded by the baffle plate 6 and the baffle plate 5. From here, the cold water flowing further downstream passes through the gap between the U-shaped heat transfer tubes 11 and 12, passes through the lower part of the baffle plate 5, passes through the gap 16, and comes out through the water outlet 4. Most of the water passes through the gap 16 because the flow resistance in the gap 16 is low and the resistance between the inner U-shaped heat transfer tube 11 and the outer U-shaped heat transfer tube 12 is large. Water room 9
The cold water that has reached the center of the baffle plate 5 enters the water chamber 8 through a plurality of holes 15 provided in the center of the baffle plate 5. This cold water flows from the gap between the inner U-shaped heat transfer tubes 11 to the outer U-shaped heat transfer tubes 12.
After flowing through the gap, the water flows out from the water outlet 4 to the outside. That is, a part of the cold water flowing into the water chamber 9 is formed between the shell 1 and the baffle plate 5 through the gap between the straight portions of the U-shaped heat transfer tubes 11 and 12 below the center of the shell 1. The water flows into the water chamber 8 through the gap. After that, it turns at the gap 16 formed between the shell 1 and the plate 2 and reaches the water outlet 4. The remainder of the cold water flowing into the water chamber 9 reaches the water chamber 8 from a plurality of holes 15 provided at the center of the baffle plate 5 and reaches the water outlet 4 through the gap between the U-shaped heat transfer tubes 11 and 12. At this time, since the flow resistances of the two chilled water paths can be made substantially the same, the amount of water passing through the hole 15 provided at the center of the baffle plate 5 and the amount of water passing below the baffle plate 5 can be made the same.
従って本発明によればすき間16の部分のほかに内側の
Ｕ形伝熱管11にも充分冷水が流れるので、水室８におけ

熱管の水の流れの均一化が向上する効果がある。According to the present invention, in the chamber surrounded by the baffle plate and the shell plate partitioning the U portion of the U-shaped heat transfer tube, water uniformly flows to the U portion of the inner U-shaped heat transfer tube having a large flow path resistance. The amount of heat exchange between the refrigerant and water in this portion is increased by the amount of water flowing through the inner U-shaped heat transfer tube portion, which has the effect of improving the performance of the water cooler. The U-shaped heat transfer tube
There is an effect that the uniformity of the flow of water between the inner U-shaped heat transfer tube and the outer U-shaped heat transfer tube in one room surrounding the portion is improved.
