FIELD: power engineering. ^ SUBSTANCE: heat receiving panel of a solar collector comprises at least two similar joined fragments made with a profiled surface having corrugations and connected to each other as capable of coupling and tight rigid connection to each other along the outer perimetre and inside, at the outer side of one of which there is a selective absorbing coating, an inlet and an outlet collector with nozzles. According to the invention, the profiled surface is formed as a result of plastic deformation under action of inner pressure of initially flat sheet fragments, previously tightly connected to each other, at the ends of rigid connections between corrugations there are wide triangular, round or drop-shaped tips, between them and the collectors there are interrupted seams of rigid connection, besides, the distance between the tips and the interrupted perpendicular seam makes at least point zero five and not more than one distance between neighbouring corrugations. ^ EFFECT: reduced cost, energy and material intensity, higher reliability and manufacturability of making a heat-receiving panel of a solar collector. ^ 4 cl, 2 dwg |
