Abstract
A vacuum insulating panel may include: 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; an evacuation tube extending at least partly into an aperture in one of the substrates; and an evacuation tube seal at least partially surrounding the tube. Relationship(s) between the tube, and bore(s) in the substrate for mounting the tube, may be designed to reduce tube tilting.

A vacuum insulating panel comprising:
- a first glass substrate;
- a second glass substrate;
- a plurality of spacers provided in a gap between at least the first and second glass substrates, wherein the gap is at pressure less than atmospheric pressure;
- a first bore, a second bore, and a third bore defined in the first glass substrate, the first bore being located further from the second glass substrate than is the third bore, and wherein the second bore is located between at least the first and third bores, wherein the first, second, and third bores have different sizes, wherein at least one diameter and/or width DB1 of the first bore is greater than at least one diameter and/or width DB2 of the second bore, and the diameter and/or width DB2 of the second bore is greater than at least one diameter and/or width DB3 of the third bore, so that as viewed cross sectionally at at least one location DB1>DB2>DB3;
- an evacuation tube, having a tube length TL and an outer size and/or diameter ODT, provided in the first and second bores;
- a tube seal supported on at least a first support surface at a base of the first bore and surrounding at least a periphery of the evacuation tube as viewed from above;
- wherein a second support surface, at a base of the second bore, is configured to support at least the evacuation tube;
- and
- wherein (DB2-ODT)/HB2 is no greater than 0.09, where HB2 is a height of the second bore extending from the second support surface to the first support surface.
