Diphasic cooling loop with satellite evaporators

A heat transfer system comprising:

• a main circuit forming a fluid loop, the main circuit being devoid of mechanical or gravitational or capillary pumping means, with a direction of flow in the fluid loop,
• at least one evaporator unit arranged in bypass to the main circuit, the at least one evaporator unit including
• at least one inlet pipe, arranged to collect liquid fluid from the main circuit,
• an evaporator including a porous member with capillary pumping, coupled to a heat source to be cooled,
• at least one outlet pipe having an ejection nozzle which injects the fluid in primarily vapor phase into the main circuit at least in the loop direction of flow,
• at least one cooling heat exchanger, comprising a portion of the loop main circuit and a heat exchanger coupled to a heat sink, for dissipating thermal energy.
