It consists of a refrigerator comprising a refrigerator, and a pump 7 for supplying liquid to be cooled to a cooling tank 2, which are housed in a case. In FIG. 2, the cooling tank 2 includes a cylindrical heat insulating wall 10, a liquid container 11 provided inside the heat insulating wall 10, a bottom plate 12 of the liquid container, which enters the liquid container from near the outer edge, and has a concentric The inner coil 6a rises while being wound in a shape.
The refrigerant evaporation tube 6 is then concentrically wound around the outside of the inner coil 6a to form an outer coil 6b, which again becomes the refrigerant evaporation tube 6 extending from the bottom plate 12 to the outside of the liquid container 11. In the liquid container 11, an outlet 14 for the liquid to be cooled is opened at the center of the bottom plate 12, and a partition pipe 13 is provided upright to surround the opening of the outlet 14. It reaches into the upper half of the container 11. liquid container 11
An inlet 16 for the liquid to be cooled opens at the lower part of the side wall 15, and a liquid supply pipe 17 is attached to the inlet 16 so as to send out the liquid in a substantially tangential direction to the inner circumferential surface of the side wall of the liquid container 11. ing. 18 is an overflow port, 19 is a return pipe for overflow liquid, 2
