This invention concerns a device for connecting contiguous profiled elements each having at least grooves or longitudinal housings along two opposite sides. The device comprises at least two connection angular brackets (21, 22) to be associated and fixed to elements to be connected by using screws accessible from the outside so as to determine the play between the adjacent ends, the precision adjustment of the position of the frontal surfaces and longitudinal sides of said elements, and the final blocking of the connection in the acquired position. The device is usable in particular for connecting in line, miter square or at an angle the modular panels for the composition of fluid circulation systems for the cooling or heating of locations.
The invention concerns a modular panel for the construction of fluid circulation systems for ambient cooling or heating. It comprises a metal body (11 ) with a length by choice and having a basically flat front surface (13) defined in width by two opposite longitudinal sides (12), at least one rear conduit (14) in an intermediate portion between said opposite sides and parallel to them, a thickness which decreases towards the two opposite longitudinal sides starting from said intermediate conduit, and along the two longitudinal sides, two lateral tabs (15, 16) protruding at least towards the rear and equipped for joining the identical contiguous panels side by side for the construction of a thermal radiating system.
This invention concerns a solar collector module for the formation of a thermic or photovoltaic roof, comprising a collector/thermal exchanger (11 ) between a supporting structure (12, 20, 26) and a possible sheet of transparent covering (35). The collector/exchanger is made up of an aluminium or similar solar picking up plate (14) forming one or more longitudinal ducts (16) for the circulation of a thermovector fluid. The supporting structure comprises at least two parallel supporting wood beams (12), each one fitted with a rigid metal profile (20) extending along the top side of the beam and anti-flexion lateral tie rods (26). The plate (14) rests and is fixed above the metal profiles (20) along the beams (12) and on at least a layer of thermo isolating and transparent material (13', 13') positioned between and to the sides of said beams.
This invention concerns a tubular heat exchanger, comprising and external tube (11 ) in which extends at least one internal corrugated tube (12) and where the heat exchange takes place between a first fluid flowing in a tube and a second fluid flowing in the other tube. Between the external tube (11 ) and the internal corrugated tube (12) is positioned a filiform element (13) with a helicoidal pitch acting as a spacer between said tubes along all their lengths. The external tube and the internal tube are pliable, and the helicoidal filiform element is wrapped around the internal tube and rests against the internal surface of the external tube to form an annular conduit between said tubes.

F28F 1/36 - Éléments tubulaires ou leurs ensembles avec moyens pour augmenter la surface de transfert de chaleur, p. ex. avec des ailettes, avec des saillies, avec des évidements ces moyens étant uniquement à l'extérieur de l'élément tubulaire et s'étendant obliquement les moyens étant des ailettes enroulées en hélice ou des spirales de fils
F28F 1/08 - Éléments tubulaires gaufrés ou ondulés longitudinalement
The present invention concerns a ball valve for fluids comprising essentially: a valve body (10) with a first inlet way (14) and a plurality of second outlet ways (15) - or vice versa a plurality of inlet ways and a single outlet way -, a swivel ball shutter (11 ), placed between said ways and having a passage to place in communication the first way with at least one of the second ways, selectively, a control system (13) to cause the rotation of the ball shutter as a result of at least one signal coming from outside and indicating the ways to be placed in communication from time to time.
