Claim:
1. A cooling device for cooling at least two separate heat sources, further comprising: a closed circuit in which a diphasic fluid flows; a single capillary evaporator configured to produce a pumping pressure and in thermal contact with a primary heat source which is one of the heat sources; a heat exchanger in thermal contact with a secondary heat source to be cooled and not producing any pumping pressure; at least one first condenser positioned downstream of the capillary evaporator and upstream of the heat exchanger; at least one last condenser positioned upstream of the capillary evaporator and downstream of the heat exchanger; wherein the heat exchanger and the condensers are dimensioned such that head losses in the circuit are less than a maximum capillary pressure of the capillary evaporator; and wherein a pressure of the diphasic fluid in the closed circuit continuously decreases from a capillary evaporator exit during an operation of the cooling device.
