Patent ID: 8256501

Claim:
A plate-type heat transport device, comprising: a first plate including a first bonding plane and a heat absorbing plane absorbing heat due to evaporation of a working fluid; a second plate including a second bonding plane bonded to the first bonding plane and a heat emission plane opposing the heat absorbing plane and emitting heat due to condensation of the working fluid; and a flow path two-dimensionally arranged between the heat absorbing plane and the heat emission plane to align with the heat absorbing plane and the heat emission plane, the flow path allowing the working fluid to flow therethrough for changing the phase of the working fluid, and the flow path being capable of two-dimensionally diffusing the working fluid by generating a capillary force in the condensed working fluid, wherein the flow path includes a plurality of first regions arranged in the first bonding plane facing a plurality of second regions arranged in the second bonding plane, the first regions two-dimensionally arranged at a position adjacent to the heat absorbing plane, each being a straight shape arranged in parallel with each other, the plurality of second regions two-dimensionally arranged at a position adjacent to the heat emission plane to oppose the heat absorbing plane, each being a straight shape arranged in parallel with each other to be orthogonal to each of the first regions facing the second regions.
