Solar collector device that operates according to the thermosyphon principle

摘要

Solar collector device (100), which operates according to the thermosiphon principle, with a fluid circuit (k), which comprises: - a solar collector (110) with a flow channel (111), which has an orifice of inlet (112) and an outlet opening (113) that is geodesically higher than the inlet opening (112); - a fluid reservoir (120) with an intake point (121) and a feed point (122) geodetically disposed higher than the intake point (121), wherein the fluid reservoir (120) is arranged at least partially geodesically above the solar collector (110); - a return duct (130), which hydraulically connects the inlet opening (112) of the flow channel (111) with the intake point (121) of the fluid reservoir (120); - a supply conduit (140), which hydraulically connects the outlet orifice (113) of the flow channel (111) with the feed point (122) of the fluid reservoir (120); - a valve (1), where the inlet port (2) of the valve (1) is oriented in the flow direction of the intake point (121), and the outlet port (3) of the valve (1 ) in the flow direction of the feed point (122); characterized in that the valve (1) is provided with a housing (4) that narrows in a longitudinal direction (L) from an inlet port (2) to an outlet port (3); wherein the housing (4) has an elastic material, so that the outlet orifice (3) can be elastically deformed; wherein inside said housing a first flow space (S1) is formed, which extends in a longitudinal direction (L) beyond the inlet opening (2), and outside it a second space is formed flow (S2), which extends in the longitudinal direction (L) beyond the outlet orifice (3); wherein the first flow space (S1) and the second flow space (S2) can have flow connection through the outlet orifice (3) as well as at least through a first branch (10) with a first valve bypass (11); wherein the first bypass valve (11) is temperature controlled.
