The present invention relates to a heat pipe for long distance and, in particular, to a heat pipe constituted by an evaporating unit for evaporating working fluid to form vapor, a condensing unit spaced at a long distant from the evaporating unit and discharging heat from a transferred vapor to the outside, and a transferring unit formed as a connecting tube of a general form having a single function connecting the evaporating unit and the condensing unit to transfer only the evaporated fluid vapor, wherein a working fluid supplier is formed in the evaporating unit in order to supplement the evaporated working fluid from the outside and a condensation liquid discharging unit is formed in the condensing unit in order to discharge condensation liquid generated by condensing the vapor to the outside. Accordingly, a recovery pipe formed for a condensation liquid carrying function of a connecting tube in the prior art is removed, making it possible to perform a long distance heat supply irrespectively of a ground landscape feature on which the transferring unit may lie. Also, the pipe connecting tube of a general form having a single function is formed with a heat insulator in order to prevent heat loss during the long distance transfer, whilst making it possible to reduce fabrication and material cost. As such, the heat pipe for long distance of the present invention comprises: an evaporating unit absorbing heat from the outside to evaporate working fluid contained therein; a transferring unit transferring vapor generated from the evaporating unit; and a condensing unit discharging the heat of the vapor transferred through the transferring unit to the outside, wherein the condensation liquid generated from a heat-discharge heat exchanger in the condensing unit is not recovered through a recovery path or a separate recovery pipe.
