Window mirror device for high-temperature processing environment

Abstract

The invention provides a window mirror device for a high-temperature processing environment, which comprises a front observation panel, a first packaging cover plate, a second packaging cover plate and an external shell, wherein the external shell is of a through hole structure, the front observation panel is arranged on the front side of the external shell, and the first packaging cover plate and the second packaging cover plate are arranged on the upper side and the lower side of the external shell; a window mirror is arranged in the outer shell, the window mirror is a vacuum array layer composed of multiple layers of low-radiation glass, and corrugated thermal compensators with clamping grooves are arranged on the periphery of the window mirror; the side edge of the low-radiation is installed in a clamping groove of the corrugated thermal compensator, and the corrugated thermal compensator and the low-radiation glass are bonded through high-temperature glue. The corrugated thermal compensator balances the thermal stress deformation of the observation mirror glass at high temperature, and prolongs the service life of the observation mirror glass; and comprehensive heat preservation and thermal insulation and visual field observation in a high-temperature processing environment are facilitated, and the application market is great.

Description

technical field [0001] The invention relates to the technical field of observation windows, in particular to a window mirror device used in a high-temperature processing environment. Background technique [0002] In some special processing environments, such as the additive manufacturing technology of powder bed selective laser sintering, or in the application scenarios that have special requirements for thermal insulation during processing, on the one hand, a field of view window is required for observation of the processing process, and on the other hand On the one hand, ordinary glass window mirrors cannot meet the strict requirements for thermal insulation due to a large amount of heat radiation. The "Laser Sintering (SLS) of Polyetheretherketone (PEEK) powder bed" process is used as an example to illustrate. Since the PEEK powder material is a material that is particularly sensitive to temperature, and the laser molding of PEEK powder is carried out in an environment f...
