Summary: | A heat sink is provided to cool uniformly a cooling plate and to obtain excellent cooling efficiency by installing a cooling fan in a cooling space having multiple layers. A heat sink(100) includes a cooling plate(110), a cooling unit(120), and a heat pipe(130). The cooling plate is formed by laminating a plurality of layers. A cooling space(111) is formed between the laminated layers. A penetrating hole(112) is formed at a center of the cooling plate in order to receive external air. The cooling unit includes a plurality of cooling fans(123) which are installed in an outer circumference of a central shaft(122) for receiving driving force of a motor(121) the penetrating hole of the cooling plate. The cooling fans are rotated in a circular direction in the cooling space. The heat pipe penetrates peripheries of the cooling plates in a vertical direction. The heat pipe is connected to a radiating block attached to an electronic component in order to radiate the temperature of the radiating block to the outside by using the internal evaporation heat. |
