Through the use of the salt-leaching pore forming method, a series of sintered nickel capillary wicks with variable porosity and pore characteristics were synthesized. The thermal conductivities of these wicks (both dry and wet) were evaluated by the transient plane source (TPS) method. The factors that affect thermal conductivity were found to be the porosity and the pore size distribution....
In this article, the thermal conductivity of porous sintered nickel material, filled with water, ethanediol, and glycerin was measured using a transient plane source method. As a note, the thermal performance of the loop heat pipes, is greatly affected by the effective thermal conductivity of the capillary structures. The results were compared with stated literature results and they indicated that the thermal conductivity of the porous material is heavily dependent ...
