In this study an innovative two-phase closed loop concept is proposed. This hybrid system is a combination of one or more local capillary loops with a two-phase ring (TPR). The ring provides the liquid to the capillary structure and each evaporator induces a vapor jet thanks to an injector element. The momentum exchange between the high velocity vapor flow and the low velocity single-phase, or two-phase, flow inside the ring insures the transport function. The paper discusses the governing equations of such a system and the experimental performances of a demonstrator able to transfer 470W from a 40 x 40 mm² footprint heater i.e. 29 W/cm².
