Three or more sheets are welded together to integrally define a storage tank, a plurality of layers of fluid flow channels (e.g. risers), and other desired features within the collector. The storage tank is located at a first end of the collector and a heat exchanger is provided within the storage tank. The heat exchanger is arranged to transfer heat from the storage tank to a target fluid (such as water) that is to be heated or preheated by the collector. The collector is arranged so that when it is installed, the collector may be positioned with the storage tank located generally above the fluid flow channels. The storage tank and the fluid flow channels are arranged such that when the collector is installed and filled with a working fluid, a thermosiphon effect will cause the collection of hot water within the storage tank. | 10-29-2015 |
20160025382 | Pressure Vessel Based Tower Structure - A tower structure with storing capacity for at least one medium is described. The tower structure comprising at least two substantially vertically oriented support structures for forming the tower structure, wherein at least one of the support structures comprises at least one constructive pressure vessel for forming the support structure. A method for building the tower structure also is disclosed. The pressure vessel based tower structure may have applications e.g. in wind mills and solar thermal towers. | 01-28-2016 |
20160033173 | PORTABLE SYSTEM FOR HEATING WATER WITH SOLAR ENERGY - A portable solar energy water heating system is provided. The system can include an inflow line having an inlet, at least a portion of the inflow line positionable in a body of water. The system can also include an outflow line having an outlet, at least a portion of the outflow line positionable in the body of water. The system can also include a conduit portion housed in a container housing and a magnifying glass or lens positioned over the conduit portion and configured to direct solar energy onto the conduit portion for heating water flowing therethrough between the inlet and the outlet, thereby providing heated water to the body of water. Optionally, the container portion can be at least partially filled with a substance that retains heat, such that the conduit portion is at least partially submerged in the substance. | 02-04-2016 |
