PRIMARY CONCENTRATOR WITH ADJUSTED ETENDUE COMBINED WITH SECONDARIES ASSOCIATED TO MULTIPLE RECEIVERS AND WITH CONVECTION REDUCTION

摘要

The present invention relates to primary and secondary concentrators of solar radiation. New primary concentrators of adjusted etendue combined with secondary concentrators are presented, for single of multiple receivers, capable of attaining the maximum possible concentration. The present invention also refers to devices which reduce the thermal losses by convection of the receivers.
