Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art, the following examples may be modified in various other forms, the scope of the present invention Is not limited to the following examples.

1 is a perspective view showing a self-heating wiper blade for a vehicle using a heat storage material according to a first embodiment of the present invention, Figure 2 is a self-heating wiper blade for a vehicle using a heat storage material according to a first embodiment of the present invention It is a cross-sectional view. 1 and 2, the self-heating wiper blade 100 for automobiles using the heat storage material according to the first embodiment of the present invention includes a heat storage material 110 to enable heat storage. When the temperature of the material 110 decreases due to heat storage, the material 110 generates heat to maintain the temperature.

The heat storage material 110 may be used as, for example, a phase change material (PCM) or a material causing a chemical thermal reaction, and in addition, it is called or understood as a latent heat material, a heat storage material, a heat storage material, a heat regulating material, and the like. For example, the phase change material may be an inorganic hydrate (Na ₂ SO ₄ H ₂ O, CH ₃ NaCOOH ₃ H ₂ O, etc.), organic matter (paraffins, etc.), fluorine salt, high density polyethylene (HDPE), etc. In addition, materials that accumulate large amounts of thermal energy or release stored thermal energy through phase change can be used.

The heat storage material 110 accumulates heat through a kind of physical change process that changes from one state to another, such as a solid state in a liquid state, a liquid state in a solid state, a liquid state in a gas state, and a gas state in a liquid state. It is a material that releases stored heat and absorbs heat through the phase change process between the solid state and the liquid state to solve the problem caused by the rapid temperature change, and releases the heat when the temperature decreases. All substances change the physical arrangement of molecules rather than chemical reactions such as chemical bonds or formation. In addition, the heat storage material 110 may be largely classified into organic materials and inorganic materials, and are classified into about 4,000 species. Among them, there are about 200 species of applicable materials. Examples of the organic materials include carbon and hydrogen. Examples of the hydrocarbon-based tetradecane, octadecane, nonadecane, and the like, and examples of the inorganic substance include calcium chloride in the form of a hydrate in which six water molecules are bonded.

The heat storage material 110 may be microencapsulated so as not to be eluted to the outside when it is melted by the phase change process and changed into a liquid state. Such heat storage material 110, for example, microencapsulation of the phase change material is difficult to see with the naked eye. By filling the inside of the microcapsules having a fine size of 5 ~ 20㎛ with a phase change material, such a phase conversion material is to be wrapped in a microcapsule.

The heat storage material 110 may have a different melting temperature according to various materials. That is, as water melts or freezes at 0 ° C, the phase change material melts or freezes at the characteristic melting temperature of each material. For example, a hydrocarbon-based phase change material is a material that melts at -4 ° C. While present, some materials melt at 100 ° C.

For example, the temperature maintenance process of the heat storage material 110, when melting the ice to drop the ambient temperature until it completely turns into a liquid, that is, the endothermic phenomenon occurs, the container containing the ice is maintained at 0 ℃ continuously, Even if the outside temperature drops to -10 ~ 20 ℃, the ice container is kept at 0 ℃ during the ice freezing process. That is, exothermic reactions occur to maintain the temperature even when the external temperature decreases. For example, when the material having a melting temperature of 4 ° C. is used as the phase change material, when the external temperature drops to −10 ° C., all of the heat storage materials 110 change phase Since the exothermic reaction occurs to maintain the temperature at 4 ° C to complete the wiper blade 100 can be maintained at about 4 ° C.

The wiper blade 100 may be provided with storage spaces 121 and 131 formed in a hollow so that the heat storage material 110 is filled in order to include the heat storage material 110. Such storage spaces 121 and 131 may include the wiper blade 100. Constituent components, such as wiping rubber 140 or elastic body 150 may be formed directly.

In addition, as in the present embodiment, the storage spaces 121 and 131 formed in the hollow to be filled with the heat storage material 110 may be formed in the mounting members 120 and 130 mounted on the wiper blade 100.

The mounting members 120 and 130 form hollow storage spaces 121 and 131 at the inner side to fill the heat storage material 110, and may be mounted at various positions outside or inside the wiper blade 100, and storage spaces 121 and 131. ) May have a structure for opening and closing. Therefore, by filling the heat storage material 110 in the storage spaces 121 and 131 inside, the heat storage effect is shown by the phase change of the heat storage material 110, and when the external temperature drops, the parts forming the wiper blade 100 by the heat generation effect. Can maintain the temperature.

The hollow structure of the mounting members 120 and 130 may be applied to the flat wiper blade 100 using the elastic body 150 as in the present embodiment, and may be mounted on the upper portion of the elastic body 150 or mounted inside. . On the other hand, the mounting member 120 mounted on the upper portion of the elastic body 150 is a groove or hole for exposing the bracket 160 to avoid interference with the bracket 160 to be connected to the wiper arm (not shown). It may form or have a portion surrounding the bracket 160.

As shown in FIG. 3, the mounting members 120 and 130 may have elasticity when the heat storage material 110, for example, the phase change material freezes, may have elastic wiper blades 100 (shown in FIGS. 1 and 2). In order to prevent loss of elasticity, the plurality of storage parts 122 and 132 in which the storage spaces 121 and 131 are formed may be connected to each other by the joint parts 123 and 133 made of a material that can be bent and arranged along the length direction. Therefore, the mounting members 120 and 130 have elasticity and flexibility by the joining portions 123 and 133 in which the hollow storage spaces 121 and 131 are bent, so that the curvature of the wiper blade 100 (shown in FIGS. 1 and 2) can be adjusted. By doing so, even if the heat storage material 110 is frozen and loses elasticity, the elastic force of the wiper blade 100 (shown in FIGS. 1 and 2) may be maintained.

It may be mounted, and filling the heat storage material 210, for example, a phase change material in the storage space (221,231) formed in a hollow so that the general type wiper blade 200 has a heat storage effect. In addition, it is possible to have a heat storage effect by forming a hollow storage space (not shown) in the wiping rubber 240 to fill the interior with the heat storage material 210.

In this case, the heat storage materials 310 and 410 may have a heat storage effect by coating the microencapsulated phase change material on some or all parts of the wiper blades 300 and 400.

A method of coating the heat storage material (310,410), for example, the microencapsulated phase change material on the wiping rubber (340,440) or other parts of the wiper blades (300,400) to ensure the elongation and adhesion of the parts with a binder of the coating material In order to select and use a part or all from the group consisting of polyol resin, urethane resin, epoxy resin, silicone resin, etc., in order to increase the thermal conductivity, it is possible to mix and coat the graphite fine powder in the coating material, heat storage material (310,410), binder, The solvent mixed in the coating material to store the graphite fine powder in a liquid state may be any one of methyl ethyl ketone, toluene, xylene, isoproalcohol, and butyl acetate or a combination thereof.

Can be.

In the case of using the solar heat collecting unit 670 as in the present embodiment, it can be stored not only when driving a car, but also when parking without additional energy waste, and a portion of a material through which solar heat is transmitted and heat absorbed to collect solar heat. In particular, in order to pass the solar heat well, a transparent material having excellent solar transmittance should be used, and there may be an air or vacuum layer that prevents the reflected heat between the transparent material and the heat absorbing material. Therefore, a black solar heat collecting unit 670 is installed on the surface of the wiper blade 600 so as to absorb solar heat well, and the transparent cover 671 made of a transparent material made of a light transmissive material on the outside of the solar heat collecting unit 670.

That is, a large factor affecting the absorption performance of the solar heat collected in the solar heat collecting unit 670 is the surface area, and as the surface area increases, the absorption performance of the solar heat increases, so in the case of a smooth surface, if the surface area is 100, the surface may be formed with a fine protrusion or In case of using foam rubber, the surface area is more than three times larger. Therefore, it is possible to improve the performance of absorbing solar heat or latent heat of the vehicle engine, and the area enlargement portion 672 that increases the surface area is formed by any one or a combination of protrusion molding, foam molding, and wrinkle molding. Outside irregularities may be formed, foams may be formed by foamed rubber, or the like, or wrinkles may be formed.
