“…3 However, monoporous structure was a limitation on heat transfer performance since there is a contradiction between capillary performance and gas permeability. 4 It is found that porous structure with different types of pores would improve the heat transfer performance of heat pipes because it could balance the contradiction between high capillary performance and high gas permeability. 5 Small pores maintain sufficient capillary force for mass transfer through porous media while large pores can not reduce the liquid hydraulic resistance, but also help the vaporized working fluid to escape from the wick.…”

Porous copper have been prepared by two-step foaming method using 18%-72 wt% of C 18 H 36 O 2 for the first-step foaming and 1.5 wt% of C 7 H 10 N 2 O 2 S for the second-step foaming. The effects of C 18 H 36 O 2 contents and sintering time on pore structure, capillary performance and gas permeability were studied. The results show that porosity, pumping rate and gas permeability increase with the increase of C 18 H 36 O 2 contents but decrease with the increase of sintering time. Porous copper with high pumping rate and gas permeability has potential as the support for mass and heat transfer in heat pipe.

“…Experiments showed that this design not only reduced the startup time but also reduced the operation temperature of LHP. Chen et al (2012) tested the heat performance of LHP with the double-hole sintered nickel wick. When the heat flux density was 12.8 W/cm 2 , the center temperature of the evaporator was lower than 60 o C, and the minimum thermal resistance was 0.33 K/W.…”

With fast development of electronic devices, novel strategies of thermal management have been received great attention to dissipate high heat fluxes. As an efficient heat transfer device, loop heat pipe (LHP) provides ideal solution for such purpose. Even though LHP was invented nearly half-century ago, challenges still exist on its design, fabrication and operation. The objective of this paper is to present a thorough review on LHPs, paying more attention on the working principle, advantage and configuration. The review is performed in three aspects. First, the macroscopic operation characteristics such as start-up, temperature fluctuations and anti-gravity operation are described. Second, effects of various parameters or factors such as porous wick material, pore size and micro-structure on LHPs are reviewed. Third, new concept LHPs using biporous wick and wettability modification are discussed. Finally, perspective of LHPs is presented, which guides future research and development activities, from both fundamental and application point of view.
