A vehicle and method for cleaning parabolic trough solar collectors () by means of a motorized vehicle () which includes a water tank (); front () and rear () cleaning arms, with a telescopic part having several sections, coupled at one end to a pivoting head () which supports a rotary cleaning brush () and comprises spray nozzles (), as well as proximity sensors () for the brushes (). It comprises the same number of front and rear transverse guide rails () which include a linear movement means () coupled, by means of a pivot (), to the cleaning arms (). The brushes () are movable in relation to the head () by means of a shaft () actuated by a retraction actuator () for overcoming obstacles ().

Cleaning vehicle and method for parabolic trough solar collectors

The present invention relates to a heat exchanger configured to capture energy by radiation, comprising at least one flag-shaped basic exchanger (), including: a) an input collector () and an output collector (); b) a plurality of exchange tubes () connected to the input collector () and to the output collector (), respectively, and stacked so as to halt the incident radiation, each tube () being provided in the form of a hairpin with one curved part at the head of the pin () and two arms () adjoining essentially vertically and on the largest part of the length thereof, the end of the tubes () at the pin head () being free and the tubes () being self-supported at the ends thereof connected to said collectors ().
