The effect of porous-surface defects on the thermophysical characteristics of the wicks of heat pipes
Abstract
An experimental study was carried out to investigate how the defects formed on the porous surface of heat-pipe wicks affect the capillary head. It is found that in the case where the gap between the perforated shield and the heating surface is 0.1-0.2 mm, the defects have practically no effect on the wick characteristics. The effect of the gap size on the limiting density of heat fluxes generated in the heating zone is discussed.
