Abstract

A pulsating multi-pipe heat pipe has its pipe bodies arranged in parallel and bent into a plurality of snake-shaped metal pipes, and an independent chamber is furnished respectively at both ends of the plurality of the snake-shaped metal pipes and connected-and-communicative to both ends of the snake-shaped metal pipes so as to enclose around into an open loop making the working-fluid-flows flowing in the multi-pipe body mutually cross flows to increase the driving force in the multi-pipe body, thereby enhances the heat-dissipating effect as well as successfully overcomes the horizontal, negative angle, and low-temperature unable-to-start problems in the conventional pulsating multi-pipe heat pipe.
