A heat transferring device including a heater, a cooler, and a recoverer may be provided. The heater may be configured to heat a first liquid working fluid and change the first liquid working fluid to a gaseous working fluid. The cooler may be configured to cool the gaseous working fluid supplied from the heater and change the gaseous working fluid supplied from the heater to a second liquid working fluid. The recoverer may be configured to enable the second liquid working fluid from the cooler to move to the heater. Accordingly, the second liquid working fluid of the cooler may be movable in an upward direction and then recoverable using gravity, without a separate power source.
