Recently, due to the increasing interest in pollution and health due to industrialization, interest in drinking water, which is drinking water, is increasing. In this trend, one of the devices that can easily drink clean drinking water is generally a water purifier. Recently, water purifiers are equipped with cold water supply function through cooling, hot water supply function through heating, and ice making function in addition to water purification function.

On the other hand, another form of drinking water is to electrolyze purified water to provide alkaline reduced water. It is an ionized water group to prepare and provide such alkaline reduced water. The ionizer also has a cold water supply function through cooling.

Such conventional water purifiers and ionizers utilize heat transfer in a refrigerant cycle to make cold water. In particular, due to the small capacity of the water purifier, a coil-type cooler was adopted, and the cold cold water was stored in a separate tank and provided.

However, such a conventional method has a low cooling efficiency and a small capacity, so that water at room temperature comes out after several cups of cold water is discharged. And there is a problem that takes a considerable time until the cold water comes out again.

In addition, when the cold water stored in a separate tank is not drinking for a long time there is a problem that impurities such as scale may occur to impair the health of the drink.

Here, the body portion 110 is integrally extruded to form a hollow portion in the longitudinal direction so that drinking water flows, and then bent gently repeatedly so that the 'U' shape is repeated. Body portion 110 according to the present invention is a simple manufacturing process because it is manufactured by bending integrally by extrusion molding without combining the path of the drinking water in the same manner as the conventional radiator method, such as welding, there is no welding, etc. The heat transfer efficiency is constant.

<Operation of instantaneous cooling device>

Hereinafter, an operation method of the instantaneous cooling device 20 having the above-described configuration and an operation method of the instantaneous cooling device 20 using the cooler unit 10 will be described with reference to the accompanying drawings.

First, the liquid refrigerant generated in the cooling unit 600 flows into the refrigerant inlet pipe 310. Thereafter, the refrigerant is cooled while expanding with gas and passes through the distribution pipe 320, the refrigerant passage 330, and the diesel oil pipe 350. Then, while passing through the refrigerant passage 330 in the diesel pipe 350 is collected in the collection pipe 360 and discharged through the refrigerant discharge pipe 370 is returned to the cooling unit 600.

After the separate water purification process or ionization process, the water is introduced through the inlet pipe of the cooler 100, flows through the cooled cooler 100, and is rapidly cooled before being discharged through the outlet pipe. At this time, the outer surface of the cooler 100 is exposed to the cooling water 520, the inner surface is exposed to drinking water. In order to prevent corrosion in these exposed surfaces, both inside and outside surfaces can be anodized.

If the cooler 300 is excessively operated, ice is generated on the surface of the cooler 300, and the ice gradually grows to contact the cooler 100. At this time, the icing sensor 810 of the cooler 100 detects this and transmits a signal to the control means, and the control means receiving the signal stops the compressor operation of the cooling unit 600 so that no more ice is frozen.
