In addition, it is preferable that a flow meter 16 capable of measuring the flow rate of raw water is provided on the connection pipe 13 interconnecting the first and second filters 12 and 14.

Eventually, the raw water supplied through the supply pipe 11 is filtered while passing through the first and second filters 12 and 14 in sequence. The raw water filtered in this way is supplied to the first cooling module 20 side.

The first storage cooling module 20 is

As shown in Figure 1,

It consists of a chamber structure filled with a phase change material (PCM) inside.

First, the cold storage material is a phase change material, accumulating a large amount of thermal energy or releasing stored thermal energy through the phase change process, and a material is in a solid to liquid state, a liquid to a solid state, a liquid to a gas, a gas to a liquid state. It is a substance that accumulates heat or releases stored heat by using a kind of physical change process that changes from one state to another.

These phase change materials can be largely classified into organic and inorganic substances, and about 4,000 species are classified as phase change materials, but there are about 200 types of substances that can be practically applied, and examples of organic substances are hydrocarbon-based substances consisting of carbon and hydrogen. There are substances such as tetradecane, octadecane, and nonadecane, and examples of inorganic substances include calcium chloride in the form of a hydrate in which six water molecules are bound.

To electrolyze raw water cooled while passing through the first storage cooling module 20 into cooling acidic water and cooling alkaline water,

A device that decomposes a compound using electrolysis. A diaphragm is installed between the cathode and the anode, and by passing direct current to electrolyze water, alkaline ions such as calcium ions, magnesium ions, potassium ions, and sodium ions are collected on the cathode side. Alkaline water is formed, and acidic water is formed in which acidic ions such as chloride ions and sulfur ions are collected on the anode side.

In more detail, it refers to water that is ionized by an electrochemical reaction obtained by losing electrons, and is classified into alkaline ionized water and acidic ionized water. When water is electrolyzed, the (-) pole contains a large amount of hydroxyl ions due to hydrogen gas (H₂) generation reaction (pH range 7.5 ~ 11), and alkaline ionized water rich in minerals such as Ca+, Mg+, and K+. On the other hand, in the (+) electrode, a large amount of hydrogen ions are contained by the reaction of generating oxygen gas (O₂) (pH range 3.5 to 6.5), and acidic ionized water rich in ions such as Cl-, S2-, and P3- Is created.

The principle of the electrolyzer 40 is the same as described above, and since it is a general configuration and is not a feature of the present invention, a more detailed description will be omitted.

The thermoelectric element 50

As shown in Figure 1,

It is for absorbing heat around the first cooling module 20 from one side and dissipating heat from the other side,

When an N-type semiconductor and a P-type semiconductor are used and power is supplied, a Peltier effect occurs between the semiconductors, resulting in heat absorption on one side and heat dissipation on the other side.

Eventually, by absorbing heat around the first storage cooling module 20 through the thermoelectric element 50, the cooling material of the first storage cooling module 20 is cooled as the periphery of the first storage cooling module 20 is cooled. It will help you maintain a constant temperature.

The heat dissipation module 60

As shown in Figure 1,

It is disposed on the other side of the thermoelectric element 50,

It consists of a block structure having a plurality of fins, and is disposed on the other side of the thermoelectric element 50.

As a result, heat radiated from the other side of the thermoelectric element 50 is radiated through the heat dissipation module 60, thereby increasing heat dissipation efficiency.

The second storage cooling module 70 is

As shown in Figure 1,

It is disposed on the other side of the heat dissipation module 60 and consists of a chamber structure filled with a storage coolant to cool the heat dissipation module 60.

The other side of the thermoelectric element 50 is in a high-temperature state due to heat dissipation, and if such a high-temperature state is maintained, not only the heat dissipation efficiency decreases, but also the thermoelectric element 50 may be affected. ) By cooling the heat dissipation module 60 through the cooling material, it is possible to increase the heat dissipation efficiency of the heat dissipation module 60.

On the other hand, since the cooling material of the second cooling module 70 gradually increases in temperature in the process of cooling the heat dissipation module 60, the present invention provides an acidic water supply pipe 80 and a relay pipe 90 ).

The acidic water supply pipe 80 is

1 and 2,

In order to supply the cooling acidic water electrolyzed through the electrolyzer 40 to the second storage cooling module 70, one end is connected to the cooling acidic water outlet side of the electrolyzer 40, and the other end is the second storage cooling module. It consists of a tubular structure connected to the inlet side of (70).

In particular, the acidic water supply pipe 80 extends in a state connected to the upper inlet of the second storage cooling module 70 and extends through the inside of the second storage cooling module 70 to the lower exit of the second storage cooling module 70. It is desirable to have a shape. This is to enable the cooling acidic water supplied through the acidic water supply pipe 80 to efficiently cool the storage coolant filled in the second storage cooling module 70 while passing through the interior of the second storage cooling module 70. .

Therefore, by passing the inside of the second storage cooling module 70 through the acidic water supply pipe 80 rather than discharging the cooling acidic water to the outside, the cooling material of the second storage cooling module 70 is cooled. It is possible to compensate for the cold air lost due to the cooling action on the heat dissipation module 60.

The relay pipe 90 is

As shown in Figure 2,

In order to supply the cooling acidic water that has passed through the second cooling module 70 to the radiating module 60, one end is connected to the lower outlet of the second cooling module 70 and the other end is the radiating module 60. It consists of a tubular structure connected to the side.

In particular, the tube body connected to the side of the heat dissipation module 60 may pass through the inside of the heat dissipation module 60 or surround the heat dissipation module 60 from top to bottom.

As cooling acidic water is conveyed through the acidic water supply pipe 80, primary cooling is performed on the cold storage material in the second cooling module 70, and drainage treatment may be performed to the outside, but the heat dissipation temperature of the radiating module 60 In consideration of the lower value, it is transferred through the relay pipe 90 to perform secondary cooling for the heat dissipation module 60, so that the discarded cooling acidic water can be utilized as much as possible. Eventually, the heat dissipation module 60 is cooled using the cooling acidic water supplied through the relay pipe 90.

Meanwhile, as shown in FIGS. 1 to 3, a transfer pipe 100 for interconnecting the outlet of the first storage cooling module 20 and the inlet of the electrolyzer 40 is provided, and branching from the transfer pipe 100 is provided. A final drain pipe 110 is provided, and a drain valve 130 for opening and closing a flow path is provided on the final drain pipe 110.

At this time, as shown in FIG. 1, when the relay pipe 90 is not provided, the drain pipe 120 for external drainage treatment of the cooling acidic water is provided at the lower end of the second storage cooling module 70 and the final drain pipe ( 110) are arranged in the form of interconnecting.

2, when the relay pipe 90 is provided, the drain pipe 120 for external drainage treatment of the cooling acidic water passes through the heat dissipation module 60, the relay pipe 90 and the final drain pipe It is arranged in the form of interconnecting 110.

Eventually, the raw water cooled through the first storage cooling module 20 is drained to the outside through the final drain pipe 110 when the drain valve 130 is opened and closed, and when the drain valve 130 is closed, the electrolyzer 40 Is transferred to the side. In addition, the cooling acidic water passes through the drain pipe 120 and the final drain pipe 110 after performing a primary cooling action through the acid water supply pipe 80 or after performing a secondary cooling action through the relay pipe 90. ) To the outside through the drainage treatment.

On the other hand, the present invention cools the storage cooling material of the second storage cooling module 70 by using the cooling acidic water supplied through the acidic water supply pipe 80, in another embodiment, the second storage cooling module 70 The cooling material of the second cooling module 70 may be cooled by using the cooling sheet 140 disposed on the other side of the unit. To this end, as shown in FIG. 3, the cooling sheet 140 has a sheet structure that can be fixedly attached to the other side of the chamber of the second cooling module 70 by an adhesive or a separate holder.

Although the cooling material of the second storage cooling module 70 may be cooled only with the cooling sheet 140, it is supplied to the acidic water supply pipe 80 as in FIGS. 4 and 5 in consideration of the amount of purified water used or supplied. The cooling acidic water and the cooling sheet 140 may be used together.

Here, the cooling sheet 140 is preferably made of a material having a high heat dissipation effect, and a cooling sheet made of a cooling sheet or aluminum panel manufactured by molding a composition including graphite, graphene, and carbon nanotubes, which are generally carbon materials. Can be used.

In the present invention, a cooling sheet manufactured by applying a mixture _{of expanded graphite and a titanium-based interlayer compound H 2} Ti ₃ O ₇ (HTO) on the surface of an aluminum panel to further improve the heat dissipation effect than the conventional cooling sheet as described above. Use.

The expanded graphite has a heat transfer rate of 800 W/mk, and considering that aluminum generally used as a heat dissipating material is 167 W/mk, the heat transfer and release rate may be increased by about 4 times or more. In addition, the HTO, as a compound having a layered structure, was identified as a material capable of improving heat transfer efficiency together with expanded graphite.

It has been shown that the expanded graphite and HTO are preferably blended in a weight ratio of 1:0.5 to 1:0.8, but if the content of HTO is too small, there is little difference in heat dissipation effect compared to when using only graphite, and the content of HTO It was found that there is a problem in that the durability of the cooling sheet is shortened due to a decrease in durability when this is too large.

A coating agent to be applied to an aluminum panel is prepared with the mixture of the expanded graphite and HTO, applied to the entire surface of the aluminum panel, dried and calcined at 300 to 400° C. for 1 to 5 hours to prepare a cooling sheet. It is preferable to use a slurry prepared by stirring an aqueous solution of aluminum hydroxide, phosphoric acid, and potassium carbonate. At this time, the binder is preferably mixed in a ratio of 40 to 50 parts by weight of phosphoric acid, 5 to 10 parts by weight of potassium carbonate, and 10 to 20 parts by weight of water based on 10 to 20 parts by weight of aluminum hydroxide in consideration of pH to prepare a slurry. . In addition, the binder is used in the range of 5 to 50 parts by weight. If the content of the binder is too small, the coating property is deteriorated, and even if the amount of the binder is too large, agglomeration of particles may occur, thereby reducing durability.

In the above description of the present invention, a "cold storage cold water ionizer" having a specific shape and structure has been mainly described with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art, and such modifications and changes are the present invention. It should be construed as falling within the scope of protection.
