Abstract (en)

[origin: FR2782810A1] The invention concerns glazing sheets (1) with variable absorbing power. Said glazing (1) comprises two transparent walls (2, 3) providing an inter-wall space (4) containing one of the two following fluids: either a first transparent fluid, such as air; or a second transparent fluid (5), absorbing solar energy over a very large part of the spectrum, in particular liquid water or liquid water with added alcohol. The glazing further comprises a circuit for discharging energy in the form of a bead, located at its periphery, preferably consisting of a heat pipe-exchanger. The glazing (1) also comprises means for filling up or emptying the inter-wall space (4), as well as flexible elements (7, 8) for absorbing the second fluid (5) expansion depending on temperature. The glazing can in particular be used for producing car windows.
