SOLAR COLLECTOR PLATE, PROCESS FOR PROTECTING THE OPERATION OF A SOLAR COLLECTOR, AND METHOD FOR PRODUCING A SOLAR COLLECTOR PLATE

摘要

A solar collector plate ( 2 ) has a solar radiation receiving front absorber plane ( 3 ) that is wiped at its rear side by a cooling liquid ( 4 ) flowing in channels ( 5 ). Cavities ( 7 ), preferably behind the channels ( 5 ) and integrated in the solar collector plate ( 2 ), and that can be closed off by the very liquid flow ( 4 ), provide a closed air volume that gives a dampening effect regarding kickbacks and pressure transients in the liquid ( 4 ).
