COLLECTOR Russian patent published in 1999 - IPC

FIELD: solar engineering; heat transfer from sun rays to heat storage. SUBSTANCE: collector has housing 1 accommodating heat insulation 2. Transparent insulation 3 and heat absorber 4 in the form of thin heat-transfer sheet such as copper foil are arranged on other side in housing 1. Flexible adsorber that can be prefabricated and delivered in rolls of water-absorbing material abuts against heat absorber 4 in parallel with its inner surface without any barrier placed between them.
