Heat pipe device for deep heat transfer of coal gangue dump

The invention discloses a heat pipe device for deep heat transfer of a coal gangue dump. The heat pipe device for deep heat transfer of the coal gangue dump is applied to the technical field of coal gangue dump spontaneous combustion prevention. The heat pipe device for deep heat transfer of the coal gangue dump comprises a pipe body closed at both ends, wherein the upper end of the pipe body is closed by a coupling device; the lower end of the pipe body is closely connected to a drill bit; the inside of the pipe body is sequentially provided with an evaporation section, an adiabatic section and a condensation section from bottom to top; an absorption medium is arranged in the evaporation section of the pipe body; the capacity of the absorption medium is 35-40% of the whole pipe volume; and the outer wall of the evaporation section is provided with spiral ribs. The heat pipe device for deep heat transfer of the coal gangue dump has the advantages of simple structure, novel design and high practical value; and
