Embodiment Construction

[0053] The present invention is not limited to the specific description disclosed, and the terminology used herein is for the purpose of specific description only, and is not limiting. The following description of the present invention is provided to disclose the contents of the present invention as currently known embodiments. Those skilled in the relevant art will know and understand that many variations and combinations of the various aspects of the invention can be made while still obtaining the beneficial results of the invention. The following description is provided as an illustration of the principles of the invention and not as a limitation of the invention.

[0054] The selection of the material of the cavity (4) mainly requires as low a permeability coefficient and an outgassing rate as possible so that the vacuum can be maintained for a longer period of time. Glass, ceramics, oxygen-free copper, stainless steel, aluminum, etc. are preferable.

[0055] For a cavi...

Abstract

The invention provides a vacuum glass panel with an external cavity, which is used for well solving the problem of the accommodation of a getter or other devices. The external cavity is only connected with a vacuum layer through a small pore canal or an airtight pipeline prearranged in an edge sealing layer of the vacuum glass panel, so that the influence on the stress of the vacuum glass panel is very small. The size of the internal space of the cavity and accommodating quantity can be determined as required; and meanwhile, material selection of the cavity is wide, so that the requirement of accommodation of various large-sized getters can be met. In the vacuum glass panel provided with a plurality of external cavities, the getters can be activated or deblocked segmentally as required, so that long-term preservation of a vacuum degree is facilitated.

Description

technical field [0001] The invention relates to a vacuum glass panel with an external cavity. Specifically, one or more cavities with a certain space volume are arranged outside the vacuum glass panel, and the cavities are connected with the vacuum layer of the vacuum glass panel. It can also be used in other small volume vacuum systems. Background technique [0002] The vacuum glass panel is mainly composed of a glass panel and a vacuum layer. The vacuum layer is often very thin, only 0.1 to 0.4 mm thick, and the volume is very small. In addition, the inner surface area of ​​the glass panel corresponding to the vacuum layer is large. This causes the outgassing on the inner surface of the glass panel to have a great influence on the vacuum degree of the vacuum layer. Practice and theory have proved that it is difficult for a vacuum glass panel without a getter to maintain a certain degree of vacuum for a long time. Placing the getter also requires a special approach due...
