Abstract:
1. A heat conveying structure for an electronic device, the heat conveying structure comprising: an evaporating section that is provided inside the electronic device, the evaporating section having a chamber structure with first fins erected therein, the evaporating section being thermally connected to the electronic device, the evaporating section evaporating a liquid coolant on the surfaces of the first fins to thereby change the liquid coolant to a vapor coolant, and the evaporating section sending out liquid coolant present near the first fins along with the vapor coolant as a gas-liquid two-phase flow coolant; a condensing section that is provided outside the electronic device, the condensing section having a chamber structure with second fins erected therein, the condensing section being thermally connected to a radiator provided outside the electronic device, and the condensing section changing the gas-liquid two-phase flow coolant in contact with the second fins to a liquid coolant; a vapor pipe that connects the evaporating section and the condensing section, and moves the gas-liquid two-phase flow coolant sent out from the evaporating section to the condensing section; and a liquid pipe that connects the evaporating section and the condensing section, and moves the liquid coolant from the condensing section to the evaporating section, wherein the electronic device includes an opening section, and wherein the vapor pipe and the liquid pipe are connected to the evaporating section and the condensing section through the opening section.
