Abstract
An invention proposes a solar radiation absorbing panel that serves preferably for air heating, The solar radiation absorbing panel is constructed from two metal sheets. The metal sheets are sealingly joined along their edges. The metal sheets are provided with mechanical or magnetic means; the both metal sheets are interlocked by these means along some lines or at some spots. This ensures diminishment of buckling these sheets under operating pressure and establishing of a certain distance between them with small deviations with respect to its average value. The outer side of one metal sheet is coated with a black or selective paint absorbing solar radiation.

A solar radiation absorbing panel comprising:
- two substantially parallel first and second metal sheets situated at distance of some millimeters relative one another;
- both said metal sheets are fabricated from ferromagnetic metal;
- the outer surface of said first metal sheet is covered with a paint absorbing solar radiation;
- two terminal sections of said second metal sheet are provided with openings;
- said metal sheets are sealingly joined along their edges;
- two headers are fastened on the said terminal sections of said second metal sheet;
- one of said headers is provided with an inlet connection and said other—with an outlet connection;
- there is a set of cylindrical dimples formed on said second longitudinal sheet;
- said cylindrical dimples are directed outward the spacing between said first and second metal sheets;
- permanent cylindrical magnets are placed in said cylindrical dimples;
- the height of said permanent cylindrical magnets is higher than the depth of said cylindrical dimples.
