Recently, environmental issues such as ozone layer destruction, global warming due to CO ₂ emissions, and natural environment destruction due to various environmental pollutants are emerging as global cooperative measures. Accordingly, CO _2, such as a pan-national technology and policy developments correspond to a strengthened environmental regulations, trade barriers due to the regulation of greenhouse gas emissions is being pursued.

As part of this development, the development of technologies for storing, converting, transferring and using thermal energy for efficient use of energy is being actively conducted. Among these technologies, there are chemical storage methods for storing energy as chemicals and methods for storing thermal energy using sensible and latent heat without changing the form of energy.

In order to maximize energy efficiency, studies using a new heat transfer medium having a high heat capacity have been conducted, and in particular, a study on latent heat storage method using a phase change material has been conducted.

Meanwhile, a phase change material (PCM) refers to a material capable of absorbing or dissipating a lot of heat while changing phase from solid to liquid, liquid to gas, or vice versa without changing the temperature at a specific temperature. Panels filled with phase change materials can be applied to building walls, ceilings, floors, etc. to mitigate rapid changes in room temperature by the heat storage function, which absorbs thermal changes in the room by the latent heat of phase change materials. Savings can be achieved.

The latent heat storage method, which is a thermal energy storage method using such latent heat, can store a large amount of heat per unit volume or unit weight.

However, in the heat storage method using latent heat, the phase change material usually has a melting temperature of -10 ° C to 80 ° C, and it is difficult to apply it to real life by forming and processing due to the outflow of the phase change material due to liquefaction due to temperature change. have.

Therefore, shape change should be applied when phase change material is applied to buildings. This is because there is a risk of leakage and deformation in the liquid state due to the phase change of the phase change material. Shape stabilization method to prevent the leakage of phase change material is morphological stability by impregnating, mixing or encapsulating the phase change material in materials such as gypsum board or mixing it with a material such as HDPE (high density poly ethylene). There is a way to make a phase change material

DETAILED DESCRIPTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

As used herein, the terms "about", "substantially", and the like, are used at, or in close proximity to, numerical values as are indicative of preparation and material tolerances inherent in the meanings mentioned, and are intended to be accurate or to facilitate understanding of the invention. Absolute figures are used to prevent unfair use by unscrupulous infringers.

The present invention relates to a method of filling a film with a phase change material, the step of preparing a flat film of a predetermined thickness (S1); Processing the flat film to create an uneven structure characterized by a plurality of hills and valleys (S2); Filling a filler in the uneven structure acid (S3); Bonding the base layer to the lower portion of the bone after filling the filler (S4); Filling the phase change material in the bone of the uneven structure (S5); Comprising the step of solidifying the phase change material in the film of the concave-convex structure filled with the phase change material using a cooling device (S6) and the step of bonding the protective layer on the top of the acid in the solid state of the phase change material (S7) It relates to a film filling method of a phase change material that can be.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

First, in the step (S1) of making a flat film, the film is a thermoplastic resin material that can be fused by applying high frequency or heat. The film layer is at least one of PE, PU, PP, and PS films. It is used or at least any one or more of the film and nylon film is characterized in that formed by two or more laminated.

The characteristics of PP series resin are easy to mold, excellent in strength, chemical resistance, permeability, electrical insulation, etc., and are inexpensive compared to other resins.

Generally, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and high density polyethylene (HDPE) may be classified according to density and molecular structure.

The film composed of only the PE-based resin may be weak in tensile strength, heat resistance, impact strength, and may be used by stacking several layers of nylon resin that can compensate for this.

Second, the flat film 110 is processed to make an uneven structure characterized by a plurality of hills and valleys (S2). The flat film may have a concave-convex structure by using pressure forming molds having a plurality of embossed shapes and applying pressure and heat to the upper and lower surfaces of the film 110. Flat films composed of PP series resins are generally easy to mold.

3A and 3B are perspective views showing examples of processed films. 3A is a perspective view of the concavo-convex shape, and FIG. 3B is close to a square pillar. Concave-convex shape can be in any form and there is no limitation. The filler 150 and the phase change material 120 only need to secure a space that can be contained on the mountain portion 111a and the bone portion 112a of the uneven portion.

The bone depth d of the uneven structure is characterized in that 3 ~ 30mm. The bone depth (d) varies depending on the amount of phase change material 120 filled in the bone.

Third, the filling space 150 is filled in the empty space inside the valley 112a of the uneven structure (S3). In the case of a film processed with a concave-convex structure, if the acid inside 111a is maintained in an empty space, the film 110 may be vulnerable to external pressure or impact when the film 110 filled with the phase change material 120 is stored or used. . In particular, when the phase change material filled in the bone 112a is in a liquid state, the film layer may be damaged by external impact, and thus, the filler 150 needs to be filled in the acid 111a in order to alleviate the impact. .

As the filler material 150, the characteristics should be impact resistance for maintaining the shape of the uneven structure film, and materials having characteristics such as heat resistance and flame resistance may be used depending on the intended use.

Synthetic resin may be used as the filler material 150 is expanded polystyrene or natural cork material. However, the foamed polypropylene itself is weak to heat and needs flame retardant treatment. Instead, cork material refers to a thick layer of bark between the bark and the bark, and is used as a filler because it is light, elastic, and not easily burned by heat.

Fourth, the base layer 140 is bonded to the bottom of the uneven portion 112 (S4). The base layer is for the purpose of preventing the filler 150 from leaving to the outside, as well as serves as a structural support band of the uneven structure film together with the filler 150. It may be composed of at least one of a synthetic resin film, metal plates, metal alloy plates, stone or wood.

Fifth, the phase change material is filled in the bone portion 112a of the uneven portion (S5).

There is no limitation of the phase change material in the present invention. Therefore, it may be composed of any one of organic compound series, inorganic compound series or eutectic compound series. However, the phase change material 120 should be provided.

That is, thermodynamically ① melting point in the required operating temperature range, ② latent heat of fusion per high volume of unit (i.e. loss of required volume of energy storage), ③ high thermal conductivity in solid and liquid phase, ④ energy in heat storage system Absorption and release, ⑤ small volume change in phase change and small vapor pressure at operating temperature are required. In addition, chemically ① reversible condensation and melting cycles, ② maintaining a certain quality after several condensation and melting cycles, ③ non-corrosive to building materials and ④ non-toxic, non-flammable and non-explosive substances are not limited.

Sixth, the phase change material 120 filled into the bone 112a is solidified using a cooling device (S5). A protective layer is attached to cover the top of the acid 111 of the uneven structure film to fill the inside of the uneven structure with a liquid phase change material and to prevent the phase change material from flowing out of the film valley 112 to the outside. Go through the process. This is because the phase change material 120 may flow out to the outside due to the vibration or impact during the liquid properties.

Various phase change materials 120 may be used depending on the use, and thus, the spilled phase change material 120 may be harmful to the environment or the human body. In order to prevent this, difficulties in cost and time may occur.

Therefore, in the present invention, when the phase change material 120 solidifies the phase change material 120 using a freezing device immediately after filling the phase change material 120 with the concave-convex structure, the fluidity decreases due to the characteristics of the solidified material. The likelihood of a spill is significantly reduced.

Finally, in the state in which the phase change material 120 is solidified, the protective layer 130 is bonded onto the acid 111 (S7). In the protective layer 130 of the present invention, the phase change material includes a protective film layer 131 having an external separation prevention function or a conductive layer 133 composed of a metal material having excellent thermal conductivity on the protective film layer 131. It is characterized by.

It is advantageous to use the same material or the same material for the film 110 and the protective film layer 131 forming the uneven structure. That is, at least one of the PE series, PU series, PP series and PS series films may be used, or one or more films and nylon films of two or more layers thereof may be laminated and used, and a high frequency or It can be adhered using a heat fusion process.

The protective film layer 131 is bonded to the top of the uneven structure film 110 layer acid 111 using a high frequency or heat fusion process. Since the components of the film are thermoplastic components, when heat is applied in a molten state by applying heat in a solid state, the two film layers are easily bonded together, and when solidified at room temperature, they are firmly bonded without the need for a separate adhesive.

In case of using high frequency, it is a method of bonding plastic by using vibration of sound wave. The power of 50 / 60Hz is converted to mechanical vibration energy through converter and booster by supplying electric power of 50 / 60Hz through GEMERATOR. After being converted and transferred to the workpiece through the tool horn, it generates instantaneous frictional heat due to strong vibration, and the bonding surface of the workpiece is melted and bonded to form a molecular bond.

On the other side of the bonded protective film layer 131 may be composed of a conductive layer 133 so that external heat is easily conducted to the phase change material 120. The metal material that may be used for the conductive layer 133 may be composed of any one of an aluminum alloy and a copper alloy. The thermal conductivity (W / m. ° C X 10 ² ) of the metal is about 4.12 silver (C), copper (Cu) 3.17, aluminum (Al) 1.95, chromium (Cr) 0.96, nickel (Ni) 0.84, and iron (Fe) 0.79. .

Therefore, considering the cost and conductivity, it is reasonable to use copper and aluminum as the main raw materials and other metals as alloys. The conductive layer 133 may be used or the protective film layer 131 may be used depending on the use of the phase change material 120. For example, when used in building materials, refrigerator panels, refrigeration trucks, etc., the conductive polymer film having a certain strength may be used for external shock protection and may be used for cooling goods. In this case, only a film filled with a phase change material may be used.

Figure 4 shows a cross-sectional view of the film 100 filled with a phase change material completed by the above method. The film is processed into a concave-convex structure and the bone inner portion 112a is filled with the phase change material 120 and the phase change material 120 filled with a protective layer 130 for blocking environmental pollution or harmful to the human body ( 111) Adhesion with parts. The conductive layer 133 may be bonded to the protective film 131 similar to the component of the film 110 by a high frequency or heat fusion method, and may be easily conductive on the outer surface of the protective film depending on the intended use.

In addition, by filling the filler 150 into the acid 111a of the uneven film 110 to mitigate structural weakness due to the external influence of the film filled with the phase change material 120. In addition, the filler 150 has a configuration in which the base material layer is adhered to the bone 112 so that the filler 150 is not in close contact with the acid 111a.

In another aspect, the present invention relates to a PCM filled panel manufacturing method that can be further configured to bond the heat insulating layer on the lower surface of the base layer after the bonding of the protective layer.

Figure 2 shows a flow chart related to the PCM filling panel manufacturing method of the present invention. PCM filling panel manufacturing method may further comprise the step of bonding the heat insulating layer to the lower surface of the base layer in the final step (S8) to the film filling method of the phase change material.

Hereinafter, the final step will be described further. The heat insulating layer 160 may use an air cap, which is a film containing bubbles in consideration of cost. The air cap is a shape of two or more layers of polyethylene (polyethylene) film is nested between the trapped air bubbles therebetween. In addition to being used for buffer packaging, there is also a heat insulating effect.

5 shows a cross-sectional view of a PCM filled panel completed by the above method. The flat film 110 is processed into a concave-convex structure and the bone inner portion 112a is filled with a phase change material 120 and filled with a phase change material 120 to prevent environmental pollution or harmful effects of a human body. A protective layer 130 composed of 131 is bonded to the acid 111 portion of the film processed into the uneven structure.

In addition, by filling the filler 150 into the acid 111a of the uneven film 110 to mitigate structural weakness due to the external influence of the film filled with the phase change material 120. In addition, the filler 150 is adhered to the valley 112 so that the filler 150 is not in close contact with the mountain 111a, and a heat insulating layer is bonded to the lower surface of the base layer to block the flow of heat to the outside. .

6 is composed of a plurality of protective layers 130, that is, a protective film layer 131 and a conductive layer 133 in the PCM filling panel of FIG.

As an example of the use of the PCM filling panel of the present invention, the PCM filling panel may be mainly used as a built-in drying material, the protective layer 130 to the indoor space when used, the heat insulating layer 160 toward the outer wall surface.

The protective layer 130 is made of a material having a good thermal conductivity, so that when the room temperature rises higher than the melting point of the phase change material, the protection layer 130 may prevent the room temperature from increasing further.

That is, when the melting point of the phase change material (PCM) is 25 ~ 27 ℃ when the indoor temperature exceeds the temperature in the summer season, the heat of the room is transferred to the protective layer 130 and heat is transferred to the phase change material (PCM) and absorbed Change from solid to liquid phase. At this time, it is possible to prevent the increase in the room temperature due to the absorbed heat.

The role of the heat insulation layer 160 is to concentrate the heat exchange with the indoor heat energy by passing the heat flow toward the phase change material (PCM) through the protective layer 130. If the insulating layer 160 is absent because the exchange function of the indoor heat energy due to the heat energy exchange with the phase change material (PCM) due to the movement of heat from the outside can be reduced.

In addition, the PCM filling panel of the present invention can use a phase change material (PCM) having a variety of melting point temperature in addition to the building material, and a latent heat such as a panel for a refrigerator, a refrigeration tower insulation filler, a heating panel, a constant temperature container, a cooling product (Cooling goods) Can be used for all products using Therefore, a phase change material having a melting point temperature suitable for the intended use may be selected and used among phase change materials having a melting point of 5 to 70 ° C.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
