Solar collector with heat exchanger and absorption vacuum tubes

Abstract

An absorption vacuum tube ( 2 ) with heat pipe ( 3 ), a condenser ( 4 ) of which is placed in a plugged stub pipe ( 5 ) of a dry type heat exchanger ( 1 ) of a solar collector, is characterised in that it comprises more than one heat pipe ( 3 ), preferably two to six. The plugged stub pipes ( 5 ) are located in walls of the heat exchanger ( 1 ) in groups, creating stub pipe sets, in which the condensers ( 4 ) of the heat pipes ( 3 ), situated in one absorption vacuum tube ( 2 ), are located. Thanks to the better use of a heat absorbed, the solar collector, in which the absorption heat pipes ( 3 ) and the heat exchanger ( 1 ) are used, has a better efficiency.
