Abstract
A trough-shaped collector for solar radiation for steam generation. A trough-shaped mirror extending in a longitudinal direction receives and reflects radiation onto an absorber line enclosing within its interior a steam generator tube. Heat is transferred transversely from the absorber line to the steam generator tube by a heat pipe structure.
Claims11
An elongated collector for collecting solar radiation for steam generation, said collector comprising:
- (a) a trough-shaped mirror extending in a longitudinal direction for reflecting solar radiation into a focus region extending in the longitudinal direction;
- (b) an absorber line comprising:
- (1) a longitudinally extending support having a recess with longitudinally extending edges;
- and
- (2) an absorber surface extending across and along said recess of said support and joining to said longitudinal edges to form an inner surface of said recess, said absorber surface extending in the focus region so as to intercept radiation reflected from said trough-shaped mirror;
- (c) a steam generator tube extending longitudinally within said absorber line for generating steam from water guided therein in said longitudinal direction, and
- (d) a heat pipe structure between said absorber line and said steam generator tube for transferring heat transversely from said absorber surface to said steam generator tube, said absorber surface being the heat source and said steam generator tube being the heat sink of said heat pipe structure.
