SOLAR CONCENTRATOR MODULE AND METHOD OF ITS MANUFACTURING (VERSIONS) Russian patent published in 2012 - IPC F24J2/00 F24J2/42 F24J2/46 

FIELD: power engineering.

SUBSTANCE: in a solar concentrator module comprising an optically transparent element with inlet and outlet faces of different sizes, reflecting surfaces on side faces and a radiation receiver installed on the outlet face of smaller size, the optical element is made of hardened polysiloxane gel arranged in the cavity between the inlet face comprising a protective transparent barrier, the outlet face comprising the radiation receiver, and the reflecting surfaces, and the reflecting surfaces are made in the form of a sheet thin-walled mirror reflector. In the other version of the module optically transparent elements are made of hardened polysiloxane gel arranged in the cavity between two inlet faces formed by two protective transparent barriers, side reflecting surfaces made of a sheet mirror reflector and each side of the receiver. A solar concentrator module is manufactured by generation of an optical element with inlet and outlet surfaces of different sizes and application of reflecting surfaces onto side faces of the optical element, a closed cavity is formed with side surfaces from the sheet mirror reflector, the radiation receiver on the outlet surface and the transparent protective barrier on the inlet surface, a previously vacuumised mixture of polysiloxane gel components is filled into the cavity, and polysiloxane gel is structured in the range of temperatures and duration of the process from the temperature of 20°C during 24 hours until the temperature of 150°C during 3 minutes under vibration exposure. In the other version of the method two closed cavities are formed with inlet and outlet surfaces of different sizes, the specified cavities are connected along the outlet surface of smaller section with side surfaces from the sheet mirror reflector, two closed cavities are installed with the surface of one of inlets with larger cross section to the transparent protective barrier in the horizontal plane, the surface of contact is sealed between the cavity and the protective transparent barrier, the mixture of polysiloxane gel components is filled into one of two closed cavities arranged on the protective transparent coating, the receiver is installed at the joint of outlet surfaces of smaller section of two cavities, the mixture is filled into the second closed cavity, the second protective transparent barrier is installed on the outlet surface of the second cavity, structuring is carried out in both closed cavities in the range of temperatures and duration of the process from the temperature of 20°C for 24 hours to the temperature of 150°C for 3 minutes under vibration exposure.

EFFECT: higher specific capacity of the optical element, simplified technology of photoelectric module manufacturing and its reduced cost.
