Abstract

The invention relates to a solar collector (26) including: a confined space (52) defined by an outer tube (54) and an inner tube (56) arranged inside the outer tube (54), the confined space (52) comprising a thermal insulation means suitable for reducing thermal convection and thermal conduction; a layer (58) for absorbing solar radiation (Rs) placed against the inner tube (56); and a thermal conduction means (60) suitable for transferring the heat energy received from the solar radiation (Rs) via the absorption layer (58) to a heat-transport fluid (10). The absorption layer (58) extends over only one portion of the circumference of the inner tube (56).

Description

technical field [0001] The invention relates to a solar thermal collector (capteur solaire), comprising: [0002] - a closed space defined by an inner tube and an outer tube, said inner tube being arranged inside the outer tube, said closed space comprising thermal insulation adapted to reduce heat convection and heat transfer, [0003] - a solar radiation absorbing layer arranged on the inner tube, and [0004] - Heat conduction means capable of transferring heat received from solar radiation through the absorber layer to the heat-carrying fluid. [0005] The invention also relates to a system for generating hot water through solar energy, comprising: [0006] - a plurality of solar collectors suitable for heating heat transfer fluids based on solar energy, and [0007] - Circuits that can transport heat transfer fluid between solar collectors and hot water consumers. Background technique [0008] Currently known evacuated tube solar collectors include an inner tube and...
