CONCAVE RECEIVER FOR STIRLING DISH AND MANUFACTURING METHOD THEREFOR

摘要

Concave receiver for a Stirling dish the main components of which are tubes (which form the surface on which the concentrated solar light beam falls), collectors (welded to the tubes and place the fluid that runs through the tubes in communication with the tanks), tanks (the internal areas of the collectors from which the working gas is distributed to each of the tubes) and cupolas (of which there are two types, that for housing the regenerator and the expansion cupola which is the area where the working gas is at a higher temperature) comprising a series of tubes (10, 11) extending from one collector (2), perpendicular thereto, to the other (2), also perpendicular thereto, and having a straight part (12) running from the inside of each collector (2) to the point where the tube starts to curve and a central part (13) in the shape of an arc of a circumference.
