摘要:
Device for connection between adjacent solar receiver tubes of the type which are at the end of the solar receiver tube (1) to be joined with another adjacent solar collector tube, comprising: - An expansion compensating element with at least two concentric bellows (7, 8) that are connected to each other and to a rigid ring (9) by means of a welded joint, which keeps them concentric in the expansion and compression process and joined to the glass tube (4) by the cover (12) and glass- metal transition element (21), - A connection flange (5) to connect the solar receiver tube (1) to the one adjacent thereto, the flange (5) being a round metal plate with a hole that houses the absorber tube (3), - Some through bolts (20) passing through the connection flange (5) to attach it with flange of the adjacent receiving tube (1).

The invention relates to a novel arrangement of non-evaporable getters for a tube solar collector, said tube collector being of the type that includes an outer glass tube (2); an inner metal tube (3) through which a heat-transfer fluid flows; a vacuum chamber between both tubes; and, at the ends, non-evaporable getter pellets (1) that absorb gas molecules that could produce a loss of vacuum between the inner tube (3) and the outer tube (2) and the covers (8) at which a bellows-type expansion compensating device (4) is positioned. The inner metal tube (3) and outer glass tube (2) are positioned eccentrically to one another, forming a thicker area and a narrower area in the cover (8), said narrower area being used for the positioning, by means of bonding, of the non-evaporable getter pellets (1).
摘要:
Vacuum enhancing system or non-evaporable getter of the type used en solar-receptor vacuum tubes which comprises a series of non-evaporable getter material pads the geometry of which is that of a prism with rounded corners and said pads are drilled through the centre thereof and linked by means of a cable ending in a quick-fit closure that allows the fitting thereof to be automated. This system is placed downstream of the expansion-compensating device in the form of non-radial bellows in the longitudinal direction and in the void defined by the vessel that is the interface part between the absorber tube and the expansion-compensating device. A getter system is placed in a radial arrangement, at each of the two ends of the receptor tube, resulting in a receptor tube of completely symmetrical geometry.
