Two-layer chamber slab with high requirements regarding volume and pressure, preferably for the heat exchange constructions and systems

摘要

The object of the invention is a two-layer, chamber board with high capacity and pressure requirements especially for the construction and heat exchange systems as one component specially combined by the coils of two sheets with different thicknesses in relation to each other. A two-layer, chamber plate with high capacity and pressure requirements, in particular for the construction and heat exchange systems, having two plates in the form of sheets of different thicknesses, combined with point coils arranged in a linear manner, is characterised by the fact that,the base plate is connected to the top plate by means of the four-stroke welds: circuit (3), cross-section welds (4) and cross-section welds (5) elliptical and characteristic cross-section welds (6) central welds (3, 4, 5),where the ratio of the thickness of the base plate t o the thickness of the surface is the most favourable 3/1, and formed after the dissolution of the channel (8) between the plates and the grooves (3 and 4 and 5) visible in the cross-section has a spatial, closed, spiral with radiant boundaries (10) representing the edges of the grooves (3 and 4 and 5) and has the maximum amplitude equal to 1/5 surface thickness.
