ABSTRACT:
A heat-pipe system of the two-phase fluid loop type comprising a liquid duct as a main loop for circulating a working fluid in liquid phase by a pump, an evaporator having a first capillary structure to which the working fluid is supplied from high pressure side of the main loop, a condenser having a second capillary structure for returning liquid condensate to the low pressure side of the man loop after radiating heat in the condenser, and a bypass pipe connected between the evaporator and the radiator for transporting vapor evaporated in the evaporator through its capillary structure to the second capillary of the condenser. With this construction, since the working fluid is circulated by the pump while the supply of the liquid corresponding to that evaporated in the capillary structure of the evaporator is carried out by the capillary force in the evaporator, a large amount of heat can be transported over long distances. A method of and apparatus for controlling a flow rate of a working fluid in a liquid duct of the heat-pipe system is also disclosed.
