Morphological and physical study of Cu-Ni sintered porous wicks used in heat pipes and fuel cells
Recently, the use of renewable energies has increased to environmental pollution, limitation of fossil energy resources and energy security One of the means that enable us to use such energies is fuel cells (FC). However, there are many problems in the commercialization of FC from an economically and operation perspective. One of the most important problems is heat management. New heat pipes...

متن کاملVisualization of vapor formation regimes during capillary-fed boiling in sintered-powder heat pipe wicks
The current study investigates capillary-fed boiling of water from porous sintered powder wicks used in emerging high-effective-conductivity vapor chamber heat spreaders intended for management of hot spots with heat fluxes exceeding 500 W cm . Characterization of 1 mm thick wicks composed of 100 lm sintered copper particles is performed in a test facility which replicates the capillary feeding...
متن کاملEffect of fabrication parameters on thermophysical properties of sintered wicks
Porous wicks for use in a loop heat pipe were sintered from copper and Monel powder. These wicks were characterized in terms of their shrinkage, porosity, thermal conductivity, liquid permeability and maximum capillary pressure. The effect of fabrication parameters (particle size and sintering conditions) on these properties was studied. Shrinkage was found to increase with increasing sintering...
متن کاملMetal functionalization of carbon nanotubes for enhanced sintered powder wicks
Phase change cooling schemes involving passive heat spreading devices, such as heat pipes and vapor chambers, are widely adopted for thermal management of high heat-flux technologies. In this study, carbon nanotubes (CNTs) are fabricated on a 200 lm thick sintered copper powder wick layer using microwave plasma enhanced chemical vapor deposition technique. A physical vapor deposition process is...
