In the solid ice making method, when ice grows around a coiled thin tube, the ice adhering to this thin tube acts as a heat insulating material, and the refrigerating capacity and efficiency of the refrigerator deteriorate. To do. This causes energy loss. In addition, the supercooled ice making method has been attracting attention in recent years as a system that has less influence on the performance and efficiency of a refrigerator than the solid ice making method.
As an example of this method, a spiral metal pipe is wound inside a shell-shaped hollow body, and a refrigerant supercooled to 0 ° C. or less by a refrigerator or brine is caused to flow through the shell-shaped hollow body, and then the coil tube is covered. The cooling water is passed through the cooling water to flow inside the shell-shaped hollow body, or the cold water of brine is used to bring the water to be cooled into a supercooled state to make ice. Therefore, there is an advantage that the structure does not require precision processing, the coil tube has high strength, and there is little risk of refrigerant leakage. However, the heat transfer efficiency is low, and a large heat transfer area cannot be obtained compared to the external dimensions. Therefore, to obtain a large amount of ice, it is necessary to install a large number of heat exchangers. Furthermore, the supercooling phenomenon is an extremely unstable physical phenomenon, and it always tries to move to a stable ice phase by some kind of destructive action, which causes this subcooling destruction to occur in the circulation system of the supercooled water, especially in the heat exchanger. ,
When ice occurs, the circulation system becomes blocked, making continuous ice making difficult.

A heat pipe and a resin tube are used in the heat exchanger, and a cooling medium is circulated in the jacket attached to the upper part of the heat pipe by about -10 g to cool the heat pipe. Wrap it in a spiral shape so that it closely adheres to the
Since water is circulated at a temperature of 1 to 1 degree, by cooling the upper part of the heat pipe, the water inside the resin tube tightly wound around it is cooled, and it becomes supercooled water of about -2 degrees Celsius and becomes ice. Water is sent to the heat storage tank. The ice heat storage tank and the coil-shaped resin tube constitute a circulation circuit of the water to be cooled, and when the supercooled water returns from the resin tube to the tank, a supercooling destruction plate is provided on the water surface of the tank. The supercooled water is surely destroyed by this supercooled destruction plate to become water at 0 degrees Celsius, and then returns into the tank. At this time, ice can be crystallized in the tank according to the degree of supercooling. Moreover, since a part of the refrigerant sent from the refrigerator to the jacket provided on the heat pipe from the refrigerator to the subcooling destruction plate is circulated and cooled, and ice or frost grows on the surface, This becomes ice-forming nuclei, and supercooling destruction occurs immediately before the supercooled water returns to the inside of the tank, and ice crystallizes. Furthermore, since a heater is provided at the bottom of the heat pipe, when the ice due to supercooled water crystallizes in the coiled resin tube and blockage occurs, the heater is operated to heat the heat pipe. , Melt the ice crystallized in the coiled resin tube,
The blockage can be released early and stable ice production can be performed again.
