Effect 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 …
