“…An innovative wick design and fabrication technique has been investigated to boost the effective thermal conductivity of the heat pipe relative to the monolithic sub-strate material [25]. This technique created an edge-cooled, multi-source micro-heat pipe using solutions of Laplace's equation to define the primary wick lines.…”

“…Tao et al [2] founded that the heat transfer limit of flat grooved heat pipes decrease with the increasing flattening degree. Rightley et al [3] concluded that the anisotropic wick designs of the flat heat pipe have shown robust performance improvements. Machado [4] presented the 3-D unsteady simulation of a flat heat pipe with microgrooves, and an interface tracking method to investigate the phase change of a heated liquid meniscus in every microgroove.…”

A novel flat heat pipe is put forward. The novel flat heat pipe is characteristic of its integral wick structure of microgrooves, which is made of a series of thin aluminum foils folded side by side. The thermal performance of the novel flat heat pipe under the different heat loads and incline angles has been investigated experimentally. It is found that the equivalent thermal conductivity of the novel flat heat pipe can be 12.3 times higher than that of the heat pipe material. Moreover, the novel flat heat pipe with integral micro-grooved wick has good temperature uniformity. The novel flat heat pipe can play a pronounced role in heat transfer enhancement, and be expected to be good candidates for thermal management of electronic devices.

“…The prediction of the maximum capillary pressure under a given heating load and the capillary dry-out limitations were conducted in their simulations. For additional literature about experimental investigation and numerical simulations in the flat heat pipes, one can refer to [17][18][19][20][21].…”
