Description

Technical Field [0001] The present invention relates to a cold water generator for cold water,

The present invention relates to a cold water generating apparatus for generating cold water and supplying it to a cold water mat. More particularly, the present invention relates to a cold water generating apparatus for supplying cold water to a cold water mat by applying a hydrophilic substance or superhydrophilic substance to the cooling fin, And cooling the cooling fins formed with the water film through the fan to form a water film, thereby enhancing the efficiency of cold water production.

Generally, an electric mat has been used as a mat for heating a small area with low power. However, the electric mat has a problem that it is exposed to a considerable electromagnetic wave because the heating wire is directly in contact with the human body. A hot water mat was developed that circulates the water after heating it in a circle.

Conventionally, a hot water mat is formed so as to be able to heat a mat by placing a hose pipe through which heating water can flow in a mat instead of a general electric mat heating wire, and circulating water heated by a small electric boiler into a hose pipe (tube). In this case, a hot water mat used only in the winter was provided by providing only hot water, but development of a cold water mat that can be used in the summer was required.

In this case, although a mat has been proposed in which chilled water is driven separately from hot water to drive it according to an arbitrary selection, in the case of heating, the water is heated in an external boiler and supplied to the inside of the mat The water is circulated by a circulating pump, and water is circulated through the circulating pump. After the water circulates through the bed, the water is naturally supplied to the mat by the external control device. The degree of cooling is not only small but also the temperature of the water is increased when there is a heat source in the bed to which the water is supplied.

In order to solve such a problem, there has been an effort to accommodate ice in a certain container and then to heat-exchange it. However, in a summer environment with high humidity, There is a problem that a short circuit occurs due to its characteristics. Also, due to the characteristics of the melted ice water, it was limited to practical use.

Therefore, in order to solve such a problem, in Patent Document 10-2016-0018143, it is possible to prevent electric leakage due to condensation and to prevent contamination due to condensation water caused by condensation when fresh water is thrown away And the cold water supply device is provided with a cold water supply device in which water may not flow down when the cold water supply device is separated from the main body in order to discard water in which ice is melted.

However, since the conventional cold water supply apparatus uses ice as a refrigerant, the cooling effect is lost after a certain period of time, and the initial cold water temperature is too low to cause a disease due to a decrease in body temperature.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method for forming a thin and wide water film so as to maximize a surface area of water flowing on a surface of a cooling fin by applying a hydrophilic substance or super- So that the efficiency of cold water generation is enhanced by cooling the formed cooling fins.

Another object of the present invention is to provide a cold water producing apparatus for a cold water mat which is more economical by cooling water by a simple constitution and action.

In the cold water producing apparatus for a cold water mat according to the present invention, the mat (M) is supplied with cold water by a pump (P), the main water tank is provided with a cooling pin and a fan (F) Wherein a surface of the cooling fin is coated with titanium dioxide (TiO2), and a center portion of the upper side of the cooling fin is coated with a plurality of And a plurality of insertion protrusions formed in a zigzag shape of a straight line or a curved line so as to form an irregular surface of the cooling water. The insertion protrusions are inserted into a plurality of insertion holes of the supply water tank, The cooling fins are formed in a zigzag shape of a straight line or a curved line to form a plurality of uneven surfaces in the lateral direction, The water film forming part is formed so as to maintain vertical water flow characteristics of the water by the capillary force, and water is moved to the left and right ends of the cooling fin by the capillary force at the center of the water film forming part, And a U-shaped lamp is provided to provide a gap between the cooling fin and a photocatalyst for improving water film formation and cooling performance.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a cold water generating apparatus for a cold water mat according to the present invention is provided with a main water tank 10, and a plurality of cooling fins 20 are inserted into the main water tank 10 at left and right intervals , And a supply water tank (30) is coupled to the upper side of the cooling fin (20).

The auxiliary water tank 50 is coupled to the inside of the main water tank 10 and a plurality of left and right aligned cooling A fan (F) connected to the motor and rotating is provided on the rear surface of the fin (20).

The supply water tank 30 is connected to a mat M and an intake hose 11 and a filter 12 is coupled to the water supply hose 11. The main water tank 10 and the mat M, Is connected to the outflow hose (13) by a pump (13), and a pump (P) is installed in the outflow hose (13).

As shown in FIG. 2, the cooling fin 20 is formed of aluminum or copper having a high thermal conductivity. A support 21 is formed on the upper side of the cooling fin 20. The support 21 is formed in a zigzag Thereby forming a coupling protrusion 22 which forms a plurality of uneven surfaces in the longitudinal direction.

On the lower side of the support part 21, there is formed a water film forming part 23 which is bent in a zigzag shape to form a plurality of uneven surfaces in the transverse direction, and the surface of the cooling fin 20 is formed with a water film (Hydrophilic) material or a super-hydrophilic material which lowers the surface tension so that the surface tension is reduced.

Further, since the water on the surface of the cooling fin 20 is vertically slidable due to gravity, even if it is coated with a hydrophilic or superhydrophilic material, there is a limit to spreading of the water, and the water is simply dripped.

In order to solve this problem, the present invention proposes a new structure in which a central portion of a water film forming portion 23 having a plurality of concavities and convexities is formed with a downwardly bent corner portion 23a.

That is, as shown in the enlarged view of FIG. 2, the cold water in the corner portion 23a moves the water to the left and right ends of the cooling fin 20 by capillary force, A thin and broad meniscus is formed.

The hydrophilic material or the superhydrophilic material applied to the present invention weakens the surface tension of the cooling fin 20 so that the fluid can easily spread without agglomeration, thereby further enhancing the cooling efficiency.

That is, as shown in FIG. 3, on a general surface, water droplets are formed into a circular shape by surface tension, and are formed to be laterally wide in a rectangular shape on the hydrophilic surface and spread more tightly on the bottom surface more closely on the super- The surface area of the cooling water flowing on the surface of the cooling fin 20 is maximized.

In one embodiment of the present invention, titanium dioxide (TiO2) is used as the hydrophilic substance or the superhydrophilic substance. The titanium dioxide is also referred to as titanium dioxide or titanium dioxide, and is a tasteless, odorless white powder. When titanium is exposed to air, it easily reacts with oxygen to form a titanium dioxide film. It is harmless to the environment and human body because it does not react biologically, has a large oxidizing power and is used as a photocatalyst, has a large antimicrobial action, has a malodor removal and sterilizing action.

The cooling fins 20 are connected to the lower side of the supply water tank 30 as shown in FIG. 4. The supply water tank 30 shown in FIG.

The supply water tank 30 is provided with a body 31 capable of storing therein the water transferred from the mat M and a coupling part 32 protruding downward is formed on the lower side of the body 31 And a plurality of insertion holes 33 into which the coupling protrusions 22 of the cooling fins 20 are inserted are formed in the coupling part 32 so as to communicate with the inside of the body 31 and are spaced from each other.

5, the cooling fin 20 and the supply water tank 30 are inserted into the insertion hole 33 of the coupling portion 32 and the bottom surface of the body 31 is inserted into the support portion 21 The zigzag coupling protrusions 22 are provided between the insertion holes 33 and the coupling protrusions 22 so that the front surface of the cooling plate 20 and the front surface of the cooling plate 20 are separated from each other. A plurality of spaces capable of dropping water to the rear surface are formed.

The cold water generating apparatus for a cold water mat according to the present invention configured as described above operates so that the cold water is transferred to the inside of the supply water tank 30 through the intake hose 11 via the inside of the mat M, At this time, the filter 12 filters the foreign substances contained in the water to be transferred.

The water conveyed to the supply water tank 30 flows through the insertion hole 33 to fall on the irregular surface of the coupling protrusion 22 formed vertically and drops into the water film forming portion 23 on the front surface and the rear surface of the cooling fin 20 The water reaching the water film forming part 23 spreads laterally across the uneven surface formed laterally to form a thin water film.

The reason why the water film forming portion 23 is formed as an uneven surface is to smoothly move the water supplied from the upper side to the end of the cooling fin 23, Is made possible by the capillary force generated.

At this time, in order to enhance the capillary force, it is preferable that the concavo-convex structure of the water film forming part 23 is formed to be acute between the adjacent concave and convex surfaces.

In addition, the UV lamp 40 can sterilize bacteria and viruses in the cooling fin 20. The UV lamp 40 and the titanium dioxide react with each other to promote water film formation and maximize cooling performance.

That is, the titanium dioxide is excellent in the capability of absorbing light of the UV lamp 40 to oxidize other materials, and does not dissolve in an aqueous solution, an acid, or a base solution, and performs photo-decomposition of the organic material to serve as a photocatalyst.

The band gap of titanium dioxide is 3.0 ~ 3.2eV, which is relatively large, so it absorbs ultraviolet (UV) light and acts as a photocatalyst. In particular, it can act as a photocatalyst even with light of 385nm wavelength and light of visible light region when it is mixed with organic dye with different dye or color.

On the other hand, when a water film is formed on the water film forming portion 23 of the cooling fin 20, the wind passes through the plurality of cooling fins 20 by the rotation of the fan F. As a result, The temperature of the water and the cooling fin 20 is lowered because the water film and the cooling fin 20 obtain the latent heat of evaporation.

Therefore, when water is continuously supplied to the cooling fin 20 and the wind is passed through the cooling fin 20, cold water can be generated by using latent heat of evaporation of water, which is more environment-friendly.

Since evaporation of water is affected by the wet bulb temperature and the relative humidity of the ambient air, the cold water produced by the present invention maintains a normal wet bulb temperature of about 26 ° C to 28 ° C in summer, C, it can be said that it is the optimum temperature to prevent disease caused by low temperature.

The cooled water is supplied to the mat (M) through the outflow hose (13) by falling to the main water tank (10) and circulating the water. The water that is deficient by the evaporation of water is supplied to the auxiliary water tank .

The auxiliary water tank 50 is configured to be able to supply a predetermined amount of water by sensing the water level of the main water tank 10 and opening the discharge port when the water level is below the reference value. It will be omitted from the following description.

6, a cooling fin 20a may be used. In this case, the cooling fin 20a may be bent in a zigzag shape to form a plurality of uneven surfaces in the longitudinal direction. The size of the insertion hole 33 may be enlarged so that the upper end of the water film forming part 23 can be coupled to the supply water tank 30. [

Therefore, even if the hydrophilic ability is slightly weakened depending on the performance of the coating or the material, water falling from the supply water tank 30 easily forms a water film from the upper side to the whole area so that the contact area between the water and the cooling fin 20a can be maximized have.

The shape of the water film forming portion 23 may be formed not only in a straight zigzag shape as shown in the drawing but also in a zigzag shape in a curved line. The straight line and the curved line may be formed in parallel to maximize the area of the water film.
