A heat-transporting device includes an evaporating chamber containing a coaxially-arranged evaporator in a capillary material soaked with a heat-transfer agent, said evaporator being in thermal contact with a source of heat and having an axial bore with a transverse partition in the capillary material, a vapor-jet pump serving to transform the dynamic pressure of the heat-transfer agent in the vapor phase into the static pressure of the heat-transfer agent in the liquid phase, and a heat-exchanging chamber. The evaporating chamber is provided with two end face cavities each bounded by the corresponding end face of the evaporator and walls of the chamber. The partition in the capillary material is located contiguously with that end face of the evaporator which faces the heat-exchanging chamber and is provided with through holes placing the end face cavities in communication with one another and is further provided with a diametrical passage, said passage being connected to a nozzle...
