Abstract
The invention concerns glazing sheets with variable absorbing power. The glazing comprises two transparent walls providing an inter-wall space containing one of the two following fluids: either a first transparent fluid, such as air; or a second transparent fluid, absorbing solar energy over a very large part of the spectrum, in particular liquid water or liquid water with added alcohol. The glazing further compromises a circuit for discharging energy in the form of a bead, located at its periphery, preferably consisting of a heat pip-exchanger. The glazing also comprises an apparatus for filling up or emptying the inter-wall space, as well as flexible elements for absorbing the second fluid expansion depending on temperature. The glazing can in particular be used for producing car windows.
