Abstract
A vacuum oven or vacuum furnace is disclosed having an energy distribution sleeve that conforms to the shape of an interior heating chamber. The energy distribution sleeve may be of generally annular shape, like a ring, and located in a substantially regularly spaced and offset relationship from a heating element located within walls adjacent the interior heating chamber. The energy distribution sleeve includes a thermal conductive material which absorbs and re-radiates heat emitted from the heating element, thereby providing more consistent and regular radiation fields for heat treating a work piece that is loaded on a work holding tray and, upon the vacuum oven being in an operational position, the work piece is located within the furnace chamber.
