  • Patent number: 4745906
    Abstract: The invention relates to a device for passive heat transfer between a heat source and a condenser (6) by means of a vaporizable liquid and a cycle with two phases controlled by a float valve (2, 4, 11). This device comprises a boiler (1) heated by said source and a liquid tank (9), the boiler furnishing, during a first cycle phase, vapor to the condenser which then supplies the tank with liquid, and receiving, during the second cycle phase, liquid from said tank. According to the invention, a vapor separator (3) is interposed between the boiler and the condenser, and the float valve (2, 4, 11) is disposed inside this separator and makes communicate, during the first cycle phase, the vapor space of the separator with the vapor space of the boiler (1), and, during the second cycle phase, the vapor space of the separator (3) with the vapor space of the tank (9), while cutting off these communications during the respective inverse cycle phase.

  • Patent number: 4467862
    Abstract: A device for passively transporting heat in any direction, particularly downwards, from a heat source to a heat sink, which device comprises a boiler for heating a working fluid, a container for condensing vapor of the heated working fluid, means for transferring the said vapor from the boiler to the condenser, and means for transferring the working fluid from the condenser to the boiler, the said working fluid being compelled from the condenser to the boiler, when the device is in use, by expansion of a compressible medium stored in the condenser, which medium is additionally compressed by the vapor of the working fluid when the device is in use.In one embodiment the heat source for the boiler or the boiler itself is a solar collector.
