Heat conveying structure for electronic device
Abstract:
A heat conveying structure for an electronic device according to the present invention includes: an evaporating section that has a chamber structure with first fins erected therein, is thermally connected to the electronic device, evaporates a liquid coolant on the surfaces of the first fins to thereby change the liquid coolant to a vapor coolant, and sends 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 has a chamber structure with second fins erected therein, is thermally connected to a radiator provided outside the electronic device, and changes 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.
