Recent advances in the optimization of evaporator wicks of vapor chambers: From mechanism to fabrication technologies

Effect of Copper Content on the Microstructure and Properties of the Sintered Porous Aluminum Wick

“…Vapor chambers, as a promising thermal management device with high heat dissipation efficiency, a controllable shape, and good temperature uniformity, have garnered significant attention in various applications, including aerospace, electronic components, and home appliances [1][2][3][4]. They consist of a container, capillary wick, and working fluid [5]. As the key component of vapor chambers or other heat pipes, the capillary wick, with a porous structure, provides a necessary driving force for the working fluid and plays a crucial role in determining the heat dissipation efficiency [6].…”

Characterisation and modelling of water wicking and evaporation in capillary porous media for passive and energy-efficient applications

“…A common modelling approximation requires to compare the properties of the porous matrix to a bundle of parallel tubes, retrieving a simplified analytical model describing the dynamic wicking [28][29][30] that, however, only allows to investigate 1dimensional (1-D) processes [1]. As several recent studies proposed passive devices with 2-D or 3-D geometries exploiting capillary suction [9,[31][32][33][34][35], the modelling framework should shift to a continuum description, enabling a finite element implementation of the mass transfer phenomena suitable to investigate the combined effects of more complex topologies. Furthermore, this approach becomes crucial when water transport and evaporation are affected by non-negligible heat fluxes due to conduction, convection and radiative heat transfer, e.g.…”
