• TITLE: EFFICIENCY OF FLAT SOLAR COLLECTOR WITH FINNED HEAT PIPES
• AUTHOR(S): V. M. Petkov
• ABSTRACT: The influence of the fin width, degree of filling in of the heat pipe and the kind of the glass cover on the instant characteristics of the flat solar collector with finned heat pipes has been investigated. The variation of the instant efficiency of the solar collector during the day hours, with solar heat flux and temperature of the intermediate coolant is presented.
