20110303216 | SOLAR ENERGY COLLECTION - A solar collector apparatus with Dewar-type evacuated tubes results in the more efficient collection of solar radiation by, for example, maintaining the level of a volatile liquid flowing into the solar collector so that no more than 80% of the volume of an inner cylinder of a collection tube is filled with liquid and a corresponding manifold collects the vapor produced when heat is transferred from the surface of the inner glass cylinder that absorbs solar radiation to the volatile liquid. The aforementioned apparatus may likewise be used to heat a liquid within an absorber tube, the liquid having a volatile and a non-volatile component. As heat is transferred to the liquid, a fraction of the volatile component is converted to vapor, leaving the liquid more concentrated in the non-volatile component. | 12-15-2011 |
20130312735 | OVERHEAT PROTECTION MECHANISM FOR SOLAR THERMAL COLLECTOR - An overheat protection device (OPD) is implemented independently of the circulating system of a solar thermal collector and isolated from the environment. The system facilitates operation of a solar thermal collector at elevated internal temperatures (versus reducing or ceasing operation above a critical temperature). OPD includes a heat pipe filled with at least two fluids. In a non-heat conducting state, a temperature at an evaporator portion of the heat pipe is below a transition temperature and the dual-fluid includes at least one fluid in a liquid state and at least one fluid in a gaseous state. When the temperature at the evaporator is above the pre-defined transition temperature the OPD undergoes an abrupt transition to a heat conducting state, whereby the dual-fluid transfers heat from the evaporator area to the condenser area, thus transitioning from a state of thermal isolation from an environment to one of strong thermal coupling. | 11-28-2013 |
