Abstract

A receiver used in a solar collection assembly includes a tube adapted to carry a heat transfer medium therethrough. An envelope surrounds the tube and has opposed ends and a diaphragm is interposed between each end and the tube to support the tube from the envelope. The diaphragm comprises radially oriented convolutions which minimizes the axial length of the diaphragm and hence reduces shading of the absorber tube.
