<p>Absorber (2) of solar vacuum tube, inserted into a glass tube (1) all along its length together with not less than one header (3), led through a sealed end of the tube is accomplished as a one-part or multiple element of material with good thermal diffusivity, preferentially of a plate, with a coat of absorptive layer on the surface and it is square or wavy along the length. In the cross section, its each part has a shape of an opened or closed pattern, by which the circuit of cross section of the solar vacuum tube (1), limited by its inner diameter is individually or in connection with another part mostly or entirely filled up. Each part of the absorber (2) is connected by means of one header (3) at least.</p> |
