<p>Quartz glass tubes (11) are arranged between a device (15, 16) used for bringing a translucid gaseous medium and and an evacuation device (17, 18) of the heated medium. Parallel glass strips are placed inside each tube (11). Spaces cross-pieces maintain the neighbouring glass strips at a distance which corresponds to thickness thereof. The glass strips are slightly tinted so that they absorb only in part the radiation received. The absorption coefficient of the glass strips is about 0.1 allowing about 90% of the received radiation to come out of the glass strips and enter other glass strips. Hence, all of the received energy is distributed among the totality of the glass strips so that the glass strips are uniformly heated and there is no overheated spot on the glass strips. Heat of the glass strips is transmitted to the gaseous medium circulating between the glass strips inside the tube for evacuating the heat. This device is particularly appropriate for use in a tower of an helioelectric power-station wherein a multitude of minors arranged on the ground direct the solar radiation against the top of the tower. </p> |
