Cooling and heat dissipation gravity heat pipe for coal gangue pile

The invention belongs to the technical field of coal gangue pile spontaneous combustion prevention and treatment, and discloses a cooling and heat dissipation gravity heat pipe for a coal gangue pile.The cooling and heat dissipation gravity heat pipe comprises a heat pipe main body, a spiral grooved pipe, a working medium container and a control panel. The heat pipe main body is arranged, the bottom of the heat pipe main body is provided with a working medium, one half of the heat pipe main body is embedded into the coal gangue pile, heat in the coal gangue pile is transferred to the workingmedium, the working medium is evaporated when heat reaches the working medium evaporation temperature till the top of the heat pipe main body is cooled, the working medium slides down along the innerwall of the heat pipe main body, heat transfer circulation is achieved, and the effect of reducing the temperature inside the coal gangue pile is achieved. When the heat in the coal gangue pile cannotreach the working medium ev
