HIGH PERFORMANCES VACUUM INSULATING GLAZING UNIT
The present invention concerns a vacuum insulating glazing unit (VIG) (1) comprising a planar area and comprising a first glass pane (1a) and a second glass pane (1b), k discrete spacers (Pi) distributed over the planar area and positioned between the first and second glass panes and maintaining a distance between the first and the second glass panes, wherein k >8; and a peripheral bonding seal (4) hermetically sealing the distance between the first and second glass panes defining an internal volume, V, enclosed between the first and second glass panes and bounded by an inner perimeter of the peripheral bonding seal defining the planar area, the inner perimeter having a substantially rectangular geometry extending over a length, L, along a longitudinal axis, X1, and over a width, W, along a transverse axis, X2, normal to the longitudinal axis, X1, with L>= W, wherein the inner volume is under vacuum. Instead of being arranged according to a regular array, the discrete spacers are arranged according to the stress field lines of the combination of atmospheric pressure stresses, Sigmap, applied by the atmospheric pressure on the surface of the vacuum insulating glazing, and of thermal stresses, Sigmat, resulting from a temperature difference between exterior and interior environments. This novel distribution of discrete spacers confers the VIG a strong mechanical resistance (thanks to their concentrations at strategic regions), with a low thermal conductivity (thanks to the lower number of discrete spacers used).
本发明涉及真空隔热玻璃窗单元(VIG)(1)，所述真空隔热玻璃窗单元包括平面区域并且包括：第一玻璃片(1a)和第二玻璃片(1b)；k个离散间隔件(Pi)，所述离散间隔件分布在所述平面区域之上并且定位于所述第一玻璃片与所述第二玻璃片之间并在所述第一玻璃片与所述第二玻璃片之间保持一定距离，其中并且k>8；以及周边结合密封件(4)，所述周边结合密封件气密密封所述第一玻璃片与所述第二玻璃片之间的所述距离，从而限定内部体积V，所述内部体积包围在所述第一玻璃片与所述第二玻璃片之间并且由所述周边结合密封件的限定所述平面区域的内周边界定，所述内周边具有在长度L上沿纵向轴线X1延伸且在宽度W上沿与所述纵向轴线X1垂直的横向轴线X2延伸的大致矩形几何形状，L≥W，其中所述内部体积处于真空下。代替根据规则阵列进行布置，所述离散间隔件根据由大气压在所述真空隔热玻璃窗的表面上施加的大气压应力σp和由外部环境与内部环境之间的温度差导致的热应力σt的组合的应力场线布置。离散间隔件的此新颖分布赋予所述VIG强的机械抵抗性(由于所述离散间隔件集中于策略性区)、具有低热导率(由于使用了较小数量的离散间隔件)。
