Description

ABSTRACT:
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 of the vapor-jet pump said nozzle being located in the partition and also to a vapor header which, in its turn, is connected to vapor outlets. Said outlets are provided in the form of longitudinal grooves cut in the outside surface of the evaporator between smooth annular collars which are present on the outside surface of the evaporator at the end faces thereof to prevent vapor leaks into the end face cavities. An outlet of a first conduit is located in the axial bore of the evaporator. A zone of the heat-exchanging chamber containing the heat-transfer agent with a lower heat content is connected to a suction side of the vapor-jet pump by way of the first conduit and another zone of said chamber containing the heat-transfer agent with a higher heat content is connected to a discharge side of said pump through a second conduit.
