Claim Text:
1. A cooling device, the cooling device comprising: a thermal diffusion unit, the thermal diffusion unit having a mounting surface for mounting to a heating element, the thermal diffusion unit configured to diffuse heat from the heating element; and a heat transporting unit, the heat transporting unit being laminated in a thickness direction of the thermal diffusion unit and operable to transport the heat diffused by the thermal diffusion unit; wherein: the thermal diffusion unit comprises: a first upper plate; a first lower plate spaced apart from and opposing the first upper plate; a first internal space formed by laminating the first upper plate and the first lower plate together, a first refrigerant disposed therein, the first refrigerant being sealed in the first internal space; a first vapor diffusion path formed in the first internal space, the first refrigerant being vaporized and diffused therein; the first vapor diffusion path extending in a first direction; and a first capillary channel formed in the first internal space, the first refrigerant being condensed and circulated therein; the heat transporting unit comprises: a second upper plate; a second lower plate spaced apart from and opposing the second upper plate; a second internal space formed by laminating the second upper plate and the second lower plate, a second refrigerant disposed therein, the second refrigerant being sealed into the second internal space; a second vapor diffusion path formed in the second internal space, the second refrigerant being vaporized and diffused therein; the second vapor diffusion path extending in a second direction that is different than the first direction; and a second capillary channel formed in the second internal space, the second refrigerant being condensed and circulated therein; and the thermal diffusion unit and the heat transporting unit being disposed adjacent each other and on opposite sides of a common member that separates the first and second internal spaces from each other, and wherein the first upper plate of the thermal diffusion unit and the second lower plate of the heat transporting unit are the same member and define the common member.
