Abstract: The disclosure relates to a pulsating heat pipe including channel plate. The channel plate includes first surface, second surface, first channels, second channels, first passages, second passages, at least one chamber, and at least one third passage. The first channels and the chamber are formed on the first surface, the channels are formed on the second surface, and the first passages, the second passages, and the third passage penetrate through the first and second surfaces. The chamber has a closed end located opposite to the third passage and connected to at least one of the second channels via the third passage. The first and second channels are connected via the first and second passages. The chamber has a hydraulic diameter of Dh which satisfies the following condition: D h > 2 ⁢ σ Δρ ⁢ ⁢ g , wherein σ is surface tension, Δρ is difference in density between liquid and vapor, and g is gravitational acceleration.

Abstract: A three-dimensional pulsating heat pipe includes a pipe member and a connecting member. The pipe member is coiled around an axis to form a plurality of circular pipe portions, and the circular pipe portions are arranged in order along the axis so as to form a three-dimensional coiled structure. The three-dimensional coiled structure has a heat receiving section, and the pipe member has different effective pipe cross-sectional areas on two opposite sides adjacent to the heat receiving section. The connecting member is connected to two ends of the pipe member, such that the connecting member and the pipe member together form a closed loop.
