Abstract
An ultra-supercritical (USC) tower-type solar heat absorber includes a grille-hot-plate current-sharing screen, a tube row, and a graphite filling layer. The grille-hot-plate current-sharing screen is assembled by a plurality of grille hot plates. Each of the plurality of grille hot plates includes a liquid-absorbing core and a grille, and is filled with a phase-transition working medium (such as sodium, potassium, and lithium) and pumped to a vacuum state. When sunlight is reflected and concentrated on the grille-hot-plate current-sharing screen, the phase-transition working medium absorbs heat and evaporates on an evaporation surface of a grille hot plate, is condensed on a condensation surface of the grille hot plate, and returns to the liquid-absorbing core through a grille to produce a stable two-phase flow, which allows efficient heat transfer, homogenizes a surface heat-flow density, and greatly reduces a temperature difference and a thermal stress on a surface of the grille-hot-plate current-sharing screen.
