Abstract

Supporting grid for cylindrical elements of a heat exchanger. G6B. built up strip material to form a number of sections having a lateral openings through which are arched flat spring projects. The ends of the spring are rigidly attached to the wall of the strip metal section. Part of the spring is split to form branches.
