firstly onto the right and left edge of the collector arrangement 200 according to the second alternative the reflecting rays will there hi side reflectors 112 114 that divert or reflect them as well onto the first focusing zone 130 1 of the collector arrangement 200 if the collector arrangement is designed circular the two side reflectors 112 114 can be in one piece in form of a circular ring due to the diversion caused by the side reflectors 112 114 the absorber device 120 located in the first focusing zone 130 1 is heated up more strongly fig7 shows the collector arrangement 200 according to the invention mounted into an adequate rack 210 the rack 210 serves to take for example two collectors 100 i and 100 ii which each are designed according to the design example described above referring to fig1 the different components of the collectors 100 i 100 ii i e their respective reflector appliances 110 i 110 ii and their absorber appliances 120 1 3 are each fixed within the rack and are aligned towards each other with regard to an optimal heat absorption it has to be stated especially that two focusing zones of the.
