Abstract

Grid opposes lateral displacement of solid elements which take part in heat exchange. It is assembled from strip into compartments with parallel axes. A spring plate extends longitudinally in at least one position in each compartment, when uncompressed, it is arcuately curved in its main mid-part to engage with the respective element. The ends of the spring are rigidly connected to fixed points of the compartment's sidewall. Between at least one of the fixed points and the curvative, a small part is cambered in the same direction as the curvature. The spring has at least one passage opening which extends transversely relative to the sidewall's surface.
