Embodiment Construction

[0009] figure 1 An embodiment of the present invention is given, a tubesheet absorber of welded grooved aluminum strips. figure 1 Among them, a rectangular aluminum plate absorber 2 with a slender convex groove 1 on the back is matched with a grooved aluminum strip 3 with a slender hole matching the aluminum plate absorber convex groove 1, and the two are matched. Welding, and then embed the elastic pipe 5 in the groove to make a tube sheet absorber for welding the grooved aluminum strip. The two flanges 4 of the grooved aluminum bar 3 are respectively provided with two rows of elongated holes arranged at intervals.

[0010] The design of two rows of slender holes arranged at intervals on the two flanges of the grooved aluminum strip 3 can minimize the harmful stress generated by the slender holes and allow the workpiece to slide over the assembly line during welding to keep the welding torch The position does not move.

[0011] Furthermore, ultrasonic welding facilities ca...

Abstract

The invention discloses a tube plate absorber welded with pressure tank aluminum strips, which is manufactured by matching an aluminum plate absorber with a plurality of pressure tank aluminum strips and embedding elastic pipes into the pressure tanks. The tube plate absorber is characterized by comprising the aluminum plate absorber with long and thin grooves pressed on the back, wherein the aluminum plate absorber is matched with the pressure tank aluminum strips provided with long and thin holes matched with the grooves on the aluminum plate absorber, and then the matching portions of the aluminum plate absorber and the pressure tank aluminum strips are welded. The tube plate absorber has the benefits of accurate matching locations of the pressure tank aluminum strips and the aluminum plate absorber, firm connection, low heat transfer resistance, small welding deformation, smooth surface and suitability for large-scale production. An embodiment is given by combining the figures.

Description

Technical field [0001] The invention relates to a tube sheet absorber for welding grooved aluminum strips. Background technique [0002] Solar collectors made of elastic tube-sheet structure absorbers have the advantages of frost resistance, corrosion resistance, and no scaling. However, the combination of elastic tubes and flat absorbers requires the use of metal plates to wrap elastic tubes. There is a technical scheme in which an aluminum strip with a groove is bonded to an aluminum plate absorber with an adhesive and an elastic pipe is placed in the groove. The mold fixing time of the time; there is a technical scheme of riveting aluminum strips with grooves on the flat absorber with rivets, which has the advantage of mechanical shock resistance, but the rivets will destroy the selective absorption film on the flat absorber, and Time-consuming. Contents of the invention [0003] The object of the present invention is to provide a tube sheet absorber for welding groov...
