Abstract
A vacuum insulating panel includes first and second substrates (e.g., glass substrates), a hermetic edge seal, a pump-out port, and spacers sandwiched between at least the two substrates. The gap between the substrates may be at a pressure less than atmospheric pressure to provide insulating properties. The panel may include a getter. The getter may be a thin film getter and/or may be elongated in shape. A support surface of a first recess, in which the getter is positioned, may be designed in order to improve sorption of the getter. For example, a second recess may be defined in a base of the first recess, in order to improve sorption of the getter.
Claims31
A vacuum insulating panel comprising:
- a first substrate;
- a second substrate;
- a plurality of spacers provided in a gap between at least the first and second substrates, wherein the gap is at pressure less than atmospheric pressure;
- a seal at least partially located between at least the first and second substrates;
- an elongated getter, wherein the getter as viewed from above is elongated in shape and has a ratio L/W of at least 2:1, where L represents a length of the getter, and W represents a width of the getter as viewed from above;
- wherein the getter is at least partially positioned in a first recess defined in at least one of the substrates, the getter supported by a base of the first recess;
- and
- a second recess defined in the base of the first recess so that a bottom surface of the getter is exposed to air and/or gas in the gap via the second recess, wherein the getter is positioned over so as to cover part, but not all, of the second recess.
