Mobile phones, especially smartphones, which are widely used by users, perform various tasks in the central processing unit (CPU) and because of the high processing speed, a lot of heat is generated in the central processing unit and the battery. In addition, the smart phone does not have a cooler function using a fan, unlike a computer (PC), the heat generation may become more severe as the use time is longer. Excessive heat generated by the mobile phone may slow down the operation of the mobile phone, cause program malfunctions, or cause discomfort to the user.

In addition, users use a protective case made of ordinary silicone, leather, or plastic to protect the smartphone from shocks and to design it to their taste. Cooling off the heat generated by the smartphone can be more difficult because heat is blocked through.

In order to effectively remove heat of the smart phone, a heat dissipation pad made of graphene (Graphene) is used. Since the graphene is free to move more than 100 times compared to silicon and has a honeycomb shape, it is resistant to external shocks and does not disappear due to its electrical conductivity. Therefore, the heat dissipation pad is a battery insertion part of a smartphone or a general mobile phone. It can be attached to and reduce the heat of the battery to reduce the temperature of the battery.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

1 is a view showing a cross-section of a mobile phone heat dissipation case according to an embodiment of the present invention. Referring to FIG. 1, the mobile phone heat dissipation case 100 may include a case outer surface part 120, a case heat dissipation part 130, a coating part 140, and a heat insulating part 150. As shown in FIG. 1, the mobile phone heat dissipation case 100 may be coupled to the mobile phone 110.

The case outer surface part 120 may be formed in a form surrounding the side part and the rear part of the mobile phone 110. In addition, as shown in FIG. 1, the case outer surface part 120 may be formed to surround a part of the front part of the mobile phone 120 in order to be in close contact with the mobile phone 110. The case outer surface part 120 may be formed of urethane rubber or silicone to facilitate the detachment of the mobile phone 110. As shown in FIG. 1, the outer side surface of the case outer surface part 120 is formed in an air cap shape. It can be manufactured in a convex shape, and the protection function of the mobile phone 110 can be enhanced due to the air cap shape. However, the shape of such a case outer surface portion 120 is illustrative, the case outer surface portion 120 of the mobile phone heat dissipation case 100 according to an embodiment of the present invention is formed in a honeycomb shape or a repetitive circle shape It can be modified in various forms.

The case heat dissipation unit 130 may be formed in the case outer surface part 120 and may be formed of a phase change material (PCM). That is, the case heat dissipation part 130 formed of the phase change material may fill the inside of the case outer surface part 120.

Here, the phase change material (PCM) is a material used for the purpose of storing energy or automatically maintaining a constant temperature by using the heat absorption / release effect of latent heat, also called latent heat storage material or phase transition material. Latent heat refers to the heat that is absorbed or released when a substance becomes phase change, that is, when it is changed from solid to liquid (or liquid to solid) and liquid to gas (or gas to liquid). This latent heat is much larger than the heat absorbed (or released) with temperature change without phase transition.

When the phase change material is above a certain temperature, the phase change material may cause a phase transition and rapidly absorb heat to cool the surroundings. For example, Thermostech, an energy-saving latent heat material, can be instantaneously cooled at a temperature of about 29 ° C to absorb ambient heat. This phase change material has been used as an advanced aerospace material applied to protect astronauts in extreme space environments as a temperature control material.

Phase change material constituting the case heat dissipation unit 130 according to an embodiment of the present invention, the phase change may occur when the temperature of the battery (not shown) provided in the mobile phone 110 is out of an appropriate temperature range. That is, since the appropriate temperature range of the mobile phone battery is known to be 30 to 35 ° C, when the temperature of the battery (not shown) included in the mobile phone 120 becomes 35 ° C or more, the phase change material constituting the case heat dissipation unit 130 is formed. Phase changes (e.g. from liquid to solid) can absorb ambient heat. That is, the phase change material constituting the case heat dissipation unit 130 according to an embodiment of the present invention may be instantaneously cooled at a temperature of about 35 ° C.

On the other hand, the phase change material constituting the case heat dissipation unit 130 according to an embodiment of the present invention, because in the liquid state can be directed to either side of the mobile phone heat dissipation case 100 in accordance with the user's movement, A fine blocking film may be formed inside the case heat dissipation unit 130 according to an embodiment of the present invention to prevent the phase change material from being pulled out.

As shown in FIG. 1, the coating part 140 may be formed between the case heat dissipation part 130 and the heat insulating part 150, and may be made of charcoal-added vinyl. The coating part 140 may serve to block the phase change material constituting the case heat dissipation part 130 and the airgel constituting the heat insulating part 150 from being mixed with each other. Charcoal absorbs electromagnetic waves generated by various electronic devices due to the electricity (electricity) of carbonization, and also has strong adsorption and dehumidification properties. Accordingly, the mobile phone heat dissipation case 100 according to an embodiment of the present invention has an effect of absorbing the electromagnetic waves generated from the mobile phone 110 in the coating unit 140 made of charcoal-added vinyl.

The heat insulating part 150 may be formed inside the coating part 140 and may be made of an ultra-insulating material. The ultra-insulating material may be an airgel. Airgel is a new material that has been attracting attention as a thermal insulation, shock absorber, and soundproof material since it was first discovered in the 1930s and is strong in heat, electricity, sound, impact, and weighs only three times as much as air of the same volume. Silicon oxide (SiO ₂ ). One thousandth of a thousand hairs of SiO ₂ yarns are very sparsely intertwined, and there are air molecules between the yarns and the yarns. The holes containing the air are too small to move even the air. The airgel occupies 95 to 99% of the total volume, and has properties such as ultra-thermal insulation (0.015 W / mK), transparency (transparent 90%), and ultra-lightness (0.003 to 0.35 g / cc). Aerogels can be modified to prevent them from breaking easily by adding special fibers.

As shown in FIG. 1, the heat insulating part 150 may be formed in the form of a surface parallel to the rear part of the mobile phone 110. Referring to FIG. 1, the heat insulating part 150 is shown to cover the entire rear part of the mobile phone 110, but this is illustrative and the heat insulating part 150 according to an embodiment of the present invention is a mobile phone 110 rear part. It may be formed to cover only a part of the cover portion of the battery of the mobile phone 110.
