This paper gives an outline of conceptual design works for prospective development of mechanically/capillary pumped two-phase fluid loops with space radiators. Considered first are two types of capillary pump evaporators configured as a cold plate. They basically consist of porously separated vapor/liquid channels, taking a double pipe array or a tube-included rectangular duct in shape. A newly devised sizing procedure for the two is mathematically described in the table together with empirically-determined practical design formulas. Four types of deployable/retractable rigid/flexible radiators are then considered as variable capacitance heat rejection systems feasible in the existing state of technology. A unified design/performance analysis procedure for the four is also given in the table, arranged in a convenient way for comparison.
