摘要
The invention relates to a parametric cylindrical collector having an optimised secondary reconcentrator and to a method for designing same, in which the geometry of the primary reflector is a development of the Helmet collector concept with a discontinuous curve, which makes it possible to increase the concentration C/Cmax to more than 0.52 as well as for reducing wind load. The structure is optimised to withstand the various loads to which the collector is subjected. The centre of gravity of the collector is near the axis of rotation of the collector. The geometry of the secondary reconcentrator is optimised and the collection efficiency of the collector is 100%. The secondary reconcentrator is obtained by partially mirror-coating the glass tube that maintains the vacuum in the absorber tube.
