Thermal frame for a refrigerated enclosure
First Claim
1. A thermal frame for an opening in a refrigerated enclosure, the thermal frame comprising:
- a perimeter frame segment configured to be fixed to a refrigerated enclosure along a perimeter of an opening of the refrigerated enclosure, the perimeter frame segment comprising;
a first wall configured to extend rearwardly from a frontal portion of the refrigerated enclosure,a second wall extending in a second direction from a rearward edge of the first wall, anda third wall configured to extend from the second wall toward the frontal portion of the refrigerated enclosure to define a first channel between the first, second, and third walls;
a vacuum panel fixed relative to the perimeter frame segment and comprising;
a first surface disposed rearward of the second wall,a second surface disposed rearward of the first surface and offset from the first surface by a thickness, andan evacuated chamber between the first and second surfaces; and
a mounting bracket configured to secure the perimeter frame segment to the perimeter of the opening and to support the vacuum panel, the mounting bracket comprising;
a fifth wall disposed between the second wall of the perimeter frame segment and the first surface of the vacuum panel,a seventh wall coupled to a first end of the fifth wall and extending rearward of the fifth wall,an eighth wall coupled to a second end of the fifth wall opposite the first end, and extending rearward of the fifth wall, wherein the fifth, seventh, and eighth walls at least partially define a third channel within which the vacuum panel is contained,a sixth wall configured to extend from the second end of the fifth wall toward the frontal portion of the refrigerated enclosure, wherein the eighth wall is offset from the sixth wall in the second direction, anda ninth wall extending between the sixth wall and the eighth wall to define a portion of the third channel between the sixth, eighth, and ninth walls.

Abstract
A thermal frame for an opening in a refrigerated enclosure includes a perimeter frame segment fixed to the refrigerated enclosure along a perimeter of the opening. The thermal frame includes a first vacuum panel fixed relative to the perimeter frame segment and configured to reduce heat transfer through the perimeter frame segment. The thermal frame may include a mullion frame segment fixed to the refrigerated enclosure and dividing the opening into a plurality of smaller openings. The thermal frame may include a second vacuum panel fixed relative to the mullion frame segment and configured to reduce heat transfer through the mullion frame segment.
