| Abstract: | A numerical model is developed for predicting the heat rejection characteristics of fin-tube radiator arranged with heat rejection by single side. Numerical calculations are performed to quantify the effects of several factors such as working fluid temperature, fin size and effective heat sink temperature on characteristics of heat rejection of radiators. The heat rejection capacity of radiators per unit area, the optimal fin width and the corresponding fin efficiency are achieved under specified radiator parameters. The numerical results arc applicable to practical engineering optimization design of radiators and trade-off analysis of thermal management schemes for space stations. |
