ABSTRACT:
Walk-in coolers for maintaining a chamber at a temperature are assembled from sandwich panels, which are welded together in end-to-end abutting relationship. Each panel generally has an inner metallic facing and a spaced opposed metallic facing with the space between the facings filled with a thermal insulating organic material having a coefficient of thermal conductivity of less than 0.3 Btu/hr,ft.sup.2,.degree.F./ft. The abutting ends of the inner facings are welded together to cover the crevices between the inner facings and to fill the corners between mutually perpendicular facings. A heat conducting member having a coefficient of thermal conductivity greater than about 0.3 Btu/hr,ft.sup.2,.degree.F./ft is disposed in the insulating material in contact with the inner facing adjacent the welded abutting end. The head conducting member transfers heat from the weld zone during welding to limit the temperature of the facing and retransfers the heat back to the weld zone at a lower temperature as the weld cools to ambient temperatures and simultaneously protects against the delamination of the facing from the insulating material also the burning of the insulating material. Where the heat conducting members are fixed to the inner facing, the inner facing is protected from warping by the heat conducting members.
