  • Publication number: 20150101330
    Abstract: The invention provides a method for a thermally activated closed loop heat transfer system, and requires no other external power source other than the heat which it is transferring. The system is based on a two-phase (liquid/vapor) working fluid, with heat input through an evaporator and heat rejected through a condenser. All of the mechanical power produced by an engine, driven by the high vapor quality fluid leaving the evaporator, is consumed by the pump. The pump drives the low vapor quality fluid leaving the condenser back to the evaporator. Nearly isothermal heat transport can be achieved when using a pure or azeotropic working fluid, since the operation only requires the evaporator pressure to be marginally higher than the condensers pressure.

  • Patent number: 8752616
    Abstract: A system includes a primary evaporator facilitating heat transfer by evaporating liquid to obtain vapor. The primary evaporator receives a liquid from a liquid line and outputs the vapor to a vapor line. The primary evaporator also outputs excess liquid received from the liquid line to an excess fluid line. A condensing system receives the vapor from the vapor line, and outputs the liquid and excess liquid to the liquid line. The excess liquid is obtained at least partially from a reservoir. A primary loop includes the condensing system, the primary evaporator, the liquid line, and the vapor line, and provides a heat transfer path. Similarly, a secondary loop includes the condensing system, the primary evaporator, the liquid line, the vapor line, and the excess fluid line. The secondary loop provides a venting path for removing undesired vapor within the liquid or excess liquid from the primary evaporator.

  • Patent number: 8723205
    Abstract: A thermal conductivity and phase transition heat transfer mechanism has an opto-luminescent phosphor contained within the vapor chamber of the mechanism. The housing includes a section that is thermally conductive and a member that is at least partially optically transmissive, to allow emission of light produced by excitation of the phosphor. A working fluid also is contained within the chamber. The pressure within the chamber configures the working fluid to absorb heat during operation of the lighting device, to vaporize at a relatively hot location at or near at least a portion of the opto-luminescent phosphor as the working fluid absorbs heat, to transfer heat to and condense at a relatively cold location, and to return as a liquid to the relatively hot location. Also, the working fluid is in direct contact with or contains at least a portion of the opto-luminescent phosphor.

    Abstract: A thermal conductivity and phase transition heat transfer mechanism incorporates an active optical element. Examples of active optical elements include various phosphor materials for emitting light, various electrically driven light emitters and various devices that generate electrical current or an electrical signal in response to light. The thermal conductivity and phase transition between evaporation and condensation, of the thermal conductivity and phase transition heat transfer mechanism, cools the active optical element during operation. At least a portion of the active optical element is exposed to a working fluid within a vapor tight chamber of the heat transfer mechanism. The heat transfer mechanism includes a member that is at least partially optically transmissive to allow passage of light to or from the active optical element and to seal the chamber of the heat transfer mechanism with respect to vapor contained within the chamber.

  • Publication number: 20130228309
    Abstract: The invention provides a process and apparatus for the recovery of heat energy from wastewater. Wastewater, for example grey water from a domestic residence, is introduced to a detention chamber, which provides effective decoupling between the introduction of new wastewater and the demand for heat energy from its ultimate application. A heat exchange surface, in contact with the wastewater on one side and a working fluid on the other, extracts heat from the detention chamber through thermal conduction and the working fluid is transferred, via a heat pump, to a second heat exchange surface. The second heat exchange surface, in contact with the working fluid on one side and heat energy storage media on the other, transfers heat energy to the storage media through conduction. Heat energy can then be extracted from the storage media for applications including heating of potable water, or provision of building heating.
