Abstract: A heat transferring device includes a pumping structure, and more specifically, a heat transferring device having a pumping structure, in which a working fluid of a cooling part is movable in an upward direction without a separate power source, and capable of using gravity while recovering the working fluid, and applying various heat sources to a heating part. To this end, a heat transferring device includes a heating part configured to heat a liquid working fluid and change the liquid working fluid to a gas state, a cooling part configured to cool the gaseous working fluid supplied from the heating part and change the gaseous working fluid to a liquid state, a pressurizing part configured to allow the heating part and the cooling part to communicate with each other so that the gaseous working fluid pressurizes the liquid working fluid, and a recovery part configured to move the liquid working fluid supplied from the cooling part to the heating part.
