The device for utilising solar heat has a large number of collectors (2) which are pivotable about their longitudinal axes. Each collector encloses a heat exchanger (3). Each heat exchanger has a cavity surrounded by a casing. The casing is covered by a filter covering, which behaves selectively in relation to the temperature radiation, with a specific surface exposed to the heat radiation. The casing of each heat exchanger ends with pipe pieces (43, 43') which are arranged on its end faces and which serve for supplying and removing a heat-absorbing medium. Also present are supply and removal manifold lines (41, 42) which likewise end with pipe pieces (44, 44'). Opposite each pipe piece (43, 43') of the casing lies in the axial direction a pipe piece (44, 44') of the supply or removal manifold line (41, 42), over which, to make a connection, a pipe collar (45, 45') is put. This device requires no follow-up control. It also has a simple construction, for which reason it works in a practically fault-free manner and can be adjusted effortlessly by hand. <IMAGE> |
