Thermal hydraulic characterization of stainless steel wicks for heat pipe applications.

Author(s) : CANTI G., CELATA G. P., CUMO M., FURRER M.

Summary

Heat pipe design and manufacturing require the knowledge of thermal hydraulic performances of the wicks. The aim of the work is the thermal hydraulic characterization of stainless steel wicks. Commercial sintered porous media and gauzes have been used. Thermal hydraulic characterization of the wicks is obtained through the experimental measurement of: capillary height; liquid hydraulic head; wick permeability is also evaluated; heat flux wick mass flow rate during the evaporation; and wick porosity. Concerning the heat flux, it is found to be dependent on the distance between the liquid level and the evaporating zone, the evaporating zone length, the wall superheat and the water subcooling, the contact between the heater and the wick and the superficial boundary conditions of the wick.
