Abstract: 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.

Abstract: Coil solar receiver for a Stirling disk, the main components of which are pipes (where the sun hits), collectors, tanks and cupolas (of which there are two types, one that houses the regenerator, and the expansion cupola that is the area where the working gas is at a higher temperature) that includes a series of pipes (1) that perpendicularly exit from one collector (2) and perpendicularly enter another (2) and where each pipe consists of two semicircumferential curved parts (10) and three straight parts (11) parallel to one another: a center straight part (between curve and curve) and two straight parts on the ends (between the curve and the exit of one collector (2)), the two straight end parts being located on the same plane, while the center straight part is located in a separate plane.
