| Number | Title | Issue Date |
| 7318432 | Solar collector plate method for safeguarding the operation of a solar collector and method for manufacturing a solar collector plate A solar collector plate (2) has a solar radiation receiving front absorber plane (3) that is wiped at its rear side by a cooling liquid (4) flowing in channels (5). Cavities (7), preferably behind the channels (5) and integr... | 01/15/2008 |
| 6568386 | Solar heat harnessing system The present invention was achieved in order to provide a solar thermal system, wherein using a small amount of water as a medium, solar thermal energy can be largely and efficiently collected as latent heat of saturated steam or superheated steam with 1 a... | 05/27/2003 |
| 6372978 | Wind/sun solar collection system (HS2) The present invention is a self-contained, solar powered heating and cooling system for a building. The collector has an insulated heating chamber, and a light transmissive cover and a thermostatically controlled vent. The chamber contains absorptive colu... | 04/16/2002 |
| 5113659 | Solar thermal energy receiver A plurality of heat pipes in a shell receive concentrated solar energy and transfer the energy to a heat activated system. To provide for even distribution of the energy despite uneven impingement of solar energy on the heat pipes, absence of solar energy... | 05/19/1992 |
| 4505260 | Radiant energy device Radiant energy such as solar energy is utilized to form a vapor from a liquid state of a material. Concentrated radiant energy is directed through a liquid lens to a target for absorption of the radiation. The target in this way is heated to a high temper... | 03/19/1985 |
| 4440151 | Solar heat collector A solar heat collector comprises an evacuated transparent pipe; a solar heat collection plate disposed in the transparent pipe; a heat pipe, disposed in the transparent pipe so as to contact with the solar heat collection plate, and containing an evaporab... | 04/03/1984 |
| 4437456 | Heat collector A heat collector and method suitable for efficiently and cheaply collecting solar and other thermal energy are provided. The collector employs a heat pipe in a gravity-assist mode and is not evacuated. The collector has many advantages, some of which incl... | 03/20/1984 |
| 4336837 | Entirely passive heat pipe apparatus capable of operating against gravity The disclosure is directed to an entirely passive heat pipe apparatus capable of operating against gravity for vertical distances in the order of 3 to 7 meters and more. A return conduit into which an inert gas is introduced is used to lower the specific ... | 06/29/1982 |
| 4313423 | Solar collector with heat pipe A solar collector is disclosed the constructional structure of which has been simplified in such a way that the condenser system of the collector is inserted in the channel through which the gaseous or liquid heat-transfer medium flows by means of a seali... | 02/02/1982 |
| 4311131 | Evacuated heatpipe solar collector An improved solar collector for the exploitation of the thermal energy of sunlight is disclosed, in which the absorber has a transparent pipe containing an absorbing plate connected with a channel containing a transfer-fluid having a critical temperature ... | 01/19/1982 |
| 4240405 | Solar water heater Solar water heater using the phase-change principle including a collector, a condenser, and an accumulator joined to form a natural circulation system, including a pressure accumulator and a vapor-release drum.... | 12/23/1980 |
| 4052976 | Non-tracking solar concentrator with a high concentration ratio A nontracking solar concentrator with a high concentration ratio is provided. The concentrator includes a plurality of energy absorbers which communicate with a main header by which absorbed heat is removed. Undesired heat flow of those absorbers not bein... | 10/11/1977 |
