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 loop portions, and the loop 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.

Abstract: A loop type heat dissipating apparatus with a sprayer for transferring heat between a heat source and a heat sink includes an evaporator, a condenser, and a working fluid. The evaporator contacts the heat source and includes a first chamber, a second chamber, and a sprayer disposed between therebetween. The condenser contacts the heat sink and includes a third chamber communicating with the second chamber and a wick structure disposed on one side of the third chamber. The working fluid fills the loop type heat dissipating apparatus and is turned into microdroplets via a sprayer. The sprayer impinges the microdroplets into the second chamber where the microdroplets are then evaporated by the heat source before proceeding to the third chamber for condensation, liquefaction and adhering to the wick structure. Eventually, the working fluid flows back to the first chamber under a pumping force actuated by the sprayer and completes the cycle.
