摘要

A hollow conical configuration is proposed for space radiator applications, which gives an improvement in heat loss per unit mass of about 4.8 times greater than that of the corresponding solid pin fin. It is found that there exists an optimum angle, thickness, and emissivity for which improvement in heat loss per unit mass is a maximum. The optimum angle increases with increase in height and emissivity and decreases with increase in thickness. The optimum thickness increases with increase in height and emissivity and decreases with increase in angle. The optimum emissivity increases with increase in angle and thickness and decreases with increase in height. Correlations are presented for optimum angle, thickness, emissivity, and corresponding maximum improvement in heat loss per unit mass.
