Simplified calculation procedure of a latent heat reservoir for stabilizing the temperature of electronic devices
Abstract
A simple mathematical algorithm which facilitates the design of a latent heat reservoir for stabilizing the temperature of an inflight electronic device is developed, and the behavior of paraffin wax in a heat storage capacitor is experimentally studied. The results show that in the solidification stage the heat transfer coefficient h is smaller than 35 W/sq m - C and decreases with time. During the melting process, natural convection could significantly increase h on the internal side and thereby reduce the time required to melt the section compared to the conduction process alone. Values of h up to 60 W/sq m - C can be achieved. The correlation between experimental and theoretical results is good.
