<p>A natural cooling device comprises a heat radiation unit and a cooling unit. The heat radiation unit comes in contact with a heat generation unit to radiate heat generated in the heat generation unit. The cooling unit stores the heat generation unit and cools the heat generation unit by introducing a natural flow of air from a lower part to an upper part. The cooling unit includes a first lateral side part, a slant part, a second lateral side part, the bottom part, and the top part. The first lateral side part comes in contact with the heat generation unit. The slant part faces the bottom of the first lateral side part and is extended to slope toward the first lateral side part. The second lateral side part faces the top of the first lateral side part and is extended to be parallel to the first lateral side part. The bottom part includes a first opening which is connected to the first lateral side part and the bottom of the slant part and through which the air flows inside. The top part includes a second opening which faces the bottom part and is connected the first lateral side part and the top of the second lateral side part, and through which the air is discharged.</p> |
