Abstract
A solar power conversion receiver is described. In one aspect, the solar power conversion receiver includes a circular glass envelope and an absorber tube encapsulated within the circular glass envelope. An annulus, positioned between the circular glass envelope and the outer perimeter of the absorber tube, is bifurcated by first and second fins operatively coupled to the circular glass envelope and the absorber tube. These fins create first and second annulus compartments that are substantially sealed off, or independent, from one another. The first and second fins are ductile and responsive to expansion and contraction of components in the solar power conversion receiver due to temperature effects. In one aspect, gas in the lower annulus compartment stratifies with cooler gas interfacing with the encapsulating glass envelope, and hotter gas interfacing with the hotter absorber tube, resulting reduced natural convection heat loss as compared to conventional glass encapsulated receivers.
