- the present invention relates, in general, to a solar collector for thermal collection of solar radiation. STATE OF THE TECHNIQUE
- a solar collector comprises a set of conduits through which a fluid circulates that will be a receiver of the solar thermal energy impact on the collector.
- the fluid circulates from an inlet distributor to another outlet distributor.
- the collector also contains other elements that favor the capture of solar thermal energy and the thermal exchange between these surfaces and the fluid.
- the conduits through which the fluid circulates in the collector are normally made of metal, such as copper or similar, good thermal conductor, so that the thermal energy collected in the collection elements can be easily transferred to the circulating fluid on the inside, since in these solar radiation affects surfaces outside the receiving fluid. This makes the panel result in a high weight and, consequently, its handling during assembly is complex.
- the collectors it is normal for the collectors to incorporate a glass cover that allows the passage of solar thermal energy, in addition to protecting against external actions to the set of ducts and the collector system, it also allows reducing the losses of the thermal energy captured .
