20120090599 | SOLAR WINDOW HEATER - A solar heating system for heating air beside a window is disclosed. The solar heating system effectively heats air beside a window in a room of a structure through use of one or more solar panels positioned to be heated by the sun and to transfer that heat to surrounding air via convection in moving air. In at least one embodiment, the solar panel may be a corrugated panel having at least one channel. The solar panel may be positioned such that as the solar panel is heated by the sun, heat is transferred from the solar panel to surrounding air via convection. The solar panel may be configured such that an upward flow of air forms when the air is heated, thereby creating a natural, warm air flow without need of a fan or other such device. | 04-19-2012 |
20120247455 | SOLAR COLLECTOR WITH EXPANDABLE FLUID MASS MANAGEMENT SYSTEM - Solar energy conversion systems and methods use solar collectors and working fluid management systems to provide both efficient and safe operation under a wide range of operating conditions. In one embodiment, a solar collector and at least one fluid accumulator preferably with an integral heat exchanger, and at least two mass flow regulator valves enable working fluid flow into and out of the fluid accumulator. | 10-04-2012 |
20140283816 | NATURAL CIRCULATION SOLAR SYSTEM WITH VACUUM TUBES WITH AN ACCUMULATION TANK CAVITY - Natural circulation solar system for the production of sanitary hot water having a double circuit (solar and user ones) and provided with an air gap storage tank, realized so that the connection of vacuum pipes is allowed. | 09-25-2014 |

20110030676 | DEVICE FOR A WATER TANK WITH INTEGRATED SOLAR COLLECTOR - A tank for holding water and incorporated into the tank, in at least one wall of the tank, are a plurality of undulating ridges that act as a solar collector. The tank/collector combination is housed in an insulated container with a glass top double glazed for insulation to prevent heat loss from the tank/collector at night, while not interfering with the radiated solar energy reaching the solar collector of the tank/collector. The material of the tank/collector could be a metal, glass, a type of plastic, transparent material or a combination of more than one material. Option to have a plurality of semi-spherical transparent bodies instead of undulating ridges. Option to have more than one tank/collector connected by a metal pipe that is a good heat conductor. | 02-10-2011 |
20110162640 | SOLAR COLLECTOR - A solar collector, comprising: (a) a plurality of thermosiphon tubes in which water flows, each tube having a top opening and a bottom opening; (b) a top manifold having a water inlet and water outlet and disposed at the top opening of the tubes, providing both a water feed into at least one of the plurality of tubes and a water exit from the rest of the tubes; and (c) a bottom basin connecting the bottom openings of the tubes. In some embodiments the plurality of tubes are divided into at least one inlet tube and the rest as outlet tubes by a stopper disposed in the top manifold. | 07-07-2011 |
20110259321 | HEAT DRIVEN LIQUID SELF-CIRCULATING DEVICES AND THE SYSTEM EMPLOY SAME - This application discloses a heat driven liquid self-circulating device, system and method, means the liquid system formed by said devices according to said method can be circulated automatically to transfer the heat without external pump power. In one aspect, a heat driven self-circulating device for heated liquid which used with a liquid heat collector is disclosed. The heat driven self-circulating device for heated liquid which used with a liquid heat collector, comprises an airtight container for containing heated liquid, having a wall to separate its outer and inner spaces; said inner space is filled with heated liquid partially and having a upper air/vapor space above liquid level surface and lower liquid space under liquid level surface; an inlet and a outlet arranged on said wall of the container that both are under the liquid level surface in said container, and said inlet not lower than said outlet | 10-27-2011 |
20120080027 | SOLAR RECEIVER WITH NATURAL CIRCULATION FOR GENERATING SATURATED STEAM - The invention relates to a solar receiver with natural circulation for generating saturated steam, which uses water/steam as a heat-transfer fluid and includes a combined circuit for fluid recirculation (forced circulation and natural circulation). The system comprises: water-walls which receive the radiation on the surface thereof and inside which the working fluid changes phase; riser pipes through which the water/steam mix exiting the pipes of the receiver rises towards the boiler; downpipes through which the recirculation water descends from the boiler to the receiver; and a support pump in order to increase the incident power in the receiver and start up the plant when necessary. | 04-05-2012 |
20120180781 | SOLAR HEATER SYSTEM FOR DOMESTICS WATERS - A solar heater with a primary circuit course in a panel for heating two separate inter connected storage reservoirs. | 07-19-2012 |
