  • the location of the finning elements on one pipe relative to the heat-absorbing elements on the adjacent pipe with an offset around their longitudinal axis allows even more to minimize shadows from lateral irradiation, makes the heat-exchange surfaces of the finning elements more open for absorbing scattered energy, for accessing air convecting along the ribs, and for transferring infrared radiation.

Abstract

Dans un panneau thermique de l'invention qui se présente comme un ensemble de tubes à nervures, destinés au caloporteur, les éléments nervures (2) sont disposés sur le tube (1) par rapport aux éléments nervures sur les tubes adjacents, avec un décalage dans le sens de l'axe longitudinal du tube. Les extrémités des éléments nervures sont coupées en biais à un angle «alpha » ou « bêta » par rapport à l'axe longitudinal du tube. Les éléments nervures se présentent comme une bride (3) enserrant chaque tube et possédant au moins trois nervures longitudinales (4, 5) disposées à la circonférence de la bride symétriquement au plan qui passe par l'axe longitudinal du tube. L'utilisation d'un panneau thermique dans un collecteur solaire permet d'augmenter la surface absorbant la chaleur qui est ouverte à l'énergie rayonnante et diffuse, notamment lors de l'irradiation latérale, ce qui augmente le rendement. Lorsque le panneau thermique s'utilise dans des équipements de chauffage et de refroidissement des services municipaux ou dans l'industrie, cela permet d'améliorer les conditions d'échange de chaleur par convection et par rayonnement infrarouge. Les éléments nervures peuvent en outre être décalés par rapport à l'axe longitudinal du tube. Les nervures longitudinales sont disposées sur la bride symétriquement aux deux plans qui passent par l'axe longitudinal du tuyau. On augmente encore plus le rendement.
